HiFi has always been a hot topic, and many mobile phones released recently are also focusing on HiFi sound quality: those using ES9318 DAC+ two-in-one audio chip, those using AKM HiFi chip and equipped with HUAWEI histen sound effects, and those supporting Bluetooth aptX & aptX HD HD music transmission, etc., all prove that mobile phone audio has always existed in an important position in the industry. So what is HiFi? What are the technical indicators of HiFi? What are the types of common mobile phone HiFi chips and what are their performances? You will know after reading this article.

Mobile phone HiFi, hi, no, hi. After reading these, you can be considered into the pit.

　　　　The full name of HiFi is High Fidelity, which literally translates as "high fidelity". To put it bluntly, it is a playback sound that is highly similar to the original sound. Spreading digital music on the network often needs to be suppressed, and there will be lossy and lossless compression. What we often see is that MP3 is a kind of lossy compression, which will affect the sound quality. Playing music is to convert digital signals into analog signals, and then amplify the analog signals and transmit them to headphones or speakers. HiFi is to make the final music close to the sound that the producer wants you to hear after production, that is, the sound quality is good.

　　　　Of course, sound quality and sense of hearing are not the same concept. The reason why audio is a metaphysics is that the sense of hearing varies from person to person, so there are "golden ears" and "fungus", and headphones or stereos of audio terminals will have different output performances because of various differences. At the same time, things like dolby pro logic and SRS sound effects all create distortion to improve the sense of hearing. The mobile phone HiFi we are talking about here is more about what kind of audio output the mobile phone as the output front end can have.

What are the common technical indicators of HiFi?

　　　　For audio veterans, mobile phones as the front end are often dismissive, because there is an irreparable hardware gap between mobile phone HiFi and professional audio, which the author will mention later. But for ordinary consumers, a carefully designed mobile phone with audio system is enough as a toy for getting started with audio.

　　　　I believe that there are not a few users who listen to songs on their mobile phones, but not many people know about HiFi. Moreover, when they go to see professional audio evaluation, there are many technical indicators that they can’t understand, but those who know audio are unwilling to explain more. The common technical indicators of sound system are: frequency response, signal-to-noise ratio, dynamic range, distortion, transient, stereo separation, stereo balance, audio sampling and so on. Here the author explains it separately.

　　　　frequency response: The frequency range of audio equipment during playback and the relationship between signal amplitude and frequency (amplitude-frequency characteristics). The unit of amplitude is dB, and the unit of frequency is Hz. The frequency response of the sound system should reach at least 32-18000Hz, and the signal amplitude change should be less than 2dB within this frequency range.

　　　　SNR: Logarithm of the ratio of useful signal to noise at the same reference point. At the input point of the speaker, the signal-to-noise ratio is 70dB, and the noise of one meter away from the speaker is almost inaudible, and the HiFi system generally reaches above 110dB.

　　　　dynamic range: Logarithm of the ratio of the maximum undistorted output power of audio equipment to the static system noise output power. HiFi system generally reaches more than 100dB.

　　　　degree of distortion: The degree of distortion of sound source signal when audio equipment plays back. The distortion of audio power amplifier can be divided into two categories: electrical distortion and acoustic distortion. The electrical distortion is caused by the circuit, and the acoustic distortion is caused by the speaker of the sound reproduction device. The types of electrical distortion are harmonic distortion, intermodulation distortion and transient distortion. Acoustic distortion is mainly AC interface distortion. The harmonic distortion of HiFi system is generally less than 1%.

　　　　stereo isolation: the separation degree of the left and right channels. Reflect the crosstalk degree of the left and right channels.

　　　　Stereo balance: The difference between the signal gains of the left and right channels.

　　　　transient stateRefers to those short and explosive sounds in music (especially percussion), which are usually difficult to reproduce accurately. Represents a physical quantity or phenomenon that changes between two adjacent stable States, and its change time is less than the time scale of concern.

　　　　Audio samplingDigital audio system reproduces the original sound by converting the sound wave into a series of binary data. The equipment used to realize this step is analog/digital (A/D), which samples the sound wave at the rate of tens of thousands of times per second, and each sampling records the state of the original analog sound wave at a certain moment, which is called a sample. A string of samples can be connected to describe a sound wave, and the number of samples per second is called sampling frequency or yield, and the unit is HZ (hertz). The higher the sampling frequency, the higher the acoustic frequency can be described.

Some audio chip parameters (picture quoted from love machine)

　　　　Signal-to-noise ratio, stereo separation and stereo balance can be distinguished by human ears, and other indicators need to be compared by multi-system comparison. Knowing this, it is not so difficult to understand when we look at the technical parameters of those mobile phone audio chips.

What are the common evaluation elements of HiFi we are talking about?

　　　　When watching audio evaluation, it is often confusing for beginners, because they don’t know what those evaluation elements mean. Although it is only a piece of music, there are many doorways. So here, the author selects three common evaluation factors to explain: sound resolution, frequency band and sound stage.

Sound resolving power

　　　　Analytic power intuitively means the clarity of sound and the expressive ability of detailed information. For example, this is like the resolution of a display screen. The higher the resolution, the clearer the picture, and the same is true for audio equipment. However, there is no clear quantitative index to measure it, so we can only rely on the human ear for subjective evaluation.

The higher the resolution, the more details we can "see" (picture from bilibili)

　　　　The analytical power of equipment has a comprehensive influence on human ears, including the cleanliness of the sound floor, the performance of overtones, the saturation of timbre, the clarity of sound image form, the texture of sound, etc. Simply put, it is "the ability to analyze musical details without losing information". HiFi is mostly exposed to the analytical power of earphone units. The resolving power of earphone unit is mainly related to the material, thickness and coil technology of diaphragm, which requires high technology and is a large part of the investment in R&D by manufacturers, thus directly determining the R&D and production cost of the unit.

　　　　In addition to the clarity of sound and the amount of detailed information, the benefits brought by high resolution are obvious separation of human voices and musical instruments. The so-called degree of separation is the layering of music. The better the layering, the easier it is for us to distinguish between human voices and background music, and the voices with low degree of separation will be mixed with instrumental sounds.

　　　　Of course, the degree of separation can be adjusted to a certain extent, such as reducing low frequencies and highlighting middle and high frequencies, so that the details will be clear, but the problem is that the amount of information in low frequencies is reduced, and then the music will appear thin.

　　　　But too high resolution will also bring problems, that is, distortion. Generally, earphones with higher price will have higher resolution, but the resolution will be seriously distorted simply by improving the sensitivity of the unit diaphragm to current, so the resolution of low-resistance earphones will not be set too high, because the front-end (power amplifier circuit) has limited control power, and strong resolution will bring greater dynamic distortion, which is why high-end earphones are mostly high impedance.

Sennheiser HD650 with 300 ohm impedance

　　　　However, the portable mobile phone HiFi has the problem of insufficient thrust. The larger the impedance, the smaller the sensitivity, and the harder it is to push the earphone. Therefore, it is not a wise choice to buy high-impedance high-end headphones only by looking at the price. The most serious consequence of insufficient thrust is that the music is poor in dynamics, and all the detailed sounds heard at the same time will be displayed in one plane, with no ups and downs in sound, no contrast in vocal instruments, lack of emotion, and the image is just like boiled water, which is seriously distorted. In a high resolution system, besides the unit quality, the control ability of the front-end system is particularly important.

frequency band

　　　　The so-called capacity distribution of high, medium and low frequency bands refers to the quantity of each frequency band within the frequency range that the equipment can emit. Some equipment has more high-frequency bands, some have a strong sense of low frequency, and some middle-frequency bands are particularly full of voices, but the amount of high and low segments is not so much.

　　　　The requirements of high frequency for each kind of listening and everyone’s listening habits are different. For music, it is not sharp to go up to the frequency band reached by music itself, that is to say, it can be said to be excellent if it is not stuffy and lubricated; It is very difficult to connect the intermediate frequency with the high frequency and low frequency. Almost all earphones can’t perfectly interpret the thick bass and thin soprano, and at the same time perfectly interpret the characteristics of each musical instrument. Low frequency is the most difficult frequency band to do, and it is not easy to do well in dive, elasticity and overtone during playback, so high-end headphones and earplugs are all working hard in this respect.

　　　　There is no absolute difference between the quantity sense of each frequency band and the quality sense. What is important is to achieve a balance after the overall collocation. The control of each frequency band tests the ability of audio equipment, such as whether the low frequency is loose or tight, whether the high frequency is lubricated or sharp, and so on.

Sound stage

　　　　Sound stage is the range in which the sound emitted by two speakers can be condensed and formed. Usually, if the two speakers are properly positioned (including the distance from the back wall and side wall, the height of the speakers and the angle of tilting inward, etc.), a concrete sound stage will emerge. You can even "see" the positions and distances of various vocal instruments and voices behind the speakers. To put it bluntly, it is an immersive listening experience.

Sound stage’s feelings have a lot to do with the sound layout (picture quoted from Baidu Encyclopedia)

　　　　Theoretically speaking, the reason why human ears can feel the sound field is because of the loudness difference and time difference between the left and right ears. The louder the sound channel is, the closer it is to the human ear. The loudness difference between the left and right ears enables the human ear to identify the sound source. At the same time, the delay of sound (residual sound) further enhances the three-dimensional sense of sound.

　　　　But it is not easy to form a good sound stage. Because the human ear is sensitive to different frequencies, not all frequencies can distinguish the distance and orientation, and about 7kHz is the most sensitive, while the extremely high frequency and extremely low frequency sounds have no directivity or very weak directivity. Relatively speaking, low-frequency directivity is worse, and low-frequency delay is a key quality for field experience.

　　　　In addition to the field sense of sound range (width and depth), the image cohesion is also a major index to evaluate sound stage. The shape, three-dimensional degree and sense of distance of the sound are the concrete manifestations of the cohesive force. The image is to see the performance site through the sense of hearing. Different musical instruments or vocals have different positions, sizes and characteristics. What is included in the fundus is a collection of all musical instruments and vocals, but they exist alone. You can see the individual characteristics of each of them or musical instruments.

Sound stage’s excellent knot is like being at a concert (picture quoted from Southern Metropolis Daily)

　　　　The requirement of image-forming power on audio system is relatively high, which is not only related to the hardware quality and sound quality adjustment of the front end, but also the image-forming power displayed by different headphones is very different. High-performance equipment combined with optimized adjustment can show excellent presence, but for HiFi, which is only an additional function, it is a very severe test, whether from hardware support or adjustment.

　　　　Of course, in addition to these three common evaluation indicators, there are many directions for evaluating audio, such as the proportion of musical instruments and the overall balance, but after understanding the above three evaluation factors, we can understand most of the audio evaluation.

What are the code names of HiFi? What are the reasons that restrict mobile phone HiFi?

HiFi system of Xiaomi Note

　　　　When we look at manufacturers’ promotion of HiFi selling points, there are always words such as DAC, ADC and operational amplifier. But for audio white, it is often confused. Here’s a brief introduction to common terms and expressions: ADC, SRC, DAC, and operational amplifier.

Texas Instruments 51AP8LI ADC3001 audio conversion chip (picture quoted from love machine)

　　　　ADC stands for analog-to-digital signal coding chip.This device is rare in the promotion of mobile phone HiFi, and it is mainly used for audio input.

Independent double clock crystal oscillator

　　　　The sampling rate of CD is 16bit, 44.1K, and there are other sampling rates such as 48k, 96K and 192K. However, in the later processing, only one type can be processed, so a conversion is needed, and this conversion process is called SRC.This process can easily deteriorate the sound quality. Need special attention, this is a key point for smart phones to do HIFI. Such transcoding chips (such as CS8422) are expensive. At this time, an independent dual-clock crystal oscillator appears, which perfectly solves this problem: one corresponds to 44.1K, the other corresponds to 48K and its integer multiples, and what crystal oscillator is used for music in any format, which solves the SRC problem at low cost.

ES9018K2M　DAC

　　　　DAC is a relatively common component, representing a digital-to-analog signal decoding chip, and is a device for converting digital format audio files stored in mobile phones into analog signals.This is the independent audio chip that most mobile phone manufacturers promote, such as ES9018 K2M of Meizu PRO6 Plus. The quality of DAC often represents some quality parameters of the front end, such as dynamic range, signal-to-noise ratio, distortion and so on.

"539Y5P" is the AD45257 operational amplifier chip.

　　　　DAC completes analog signal conversion, but the output analog signal is very weak, and then the operational amplifier starts to operate.The full name of operational amplifier is operational amplifier. In the field of multimedia speakers, the operational amplifier chip is mainly responsible for the adjustment of volume, tone and peripheral effects., for example, integrated operational amplifiers are used in the front stage of audio and headphone amplifiers (amplifiers). For example, the common OPA1612 and OPA2604 are operational amplifier chips, and multiple operational amplifier chips can be integrated in one amp.

　　　　At present, most of the audio chips used in HiFi mobile phones on the market come from AKM and ESS. Here are some typical examples:

AK4490EN chip

　　　　AK4490EN is an ideal audio chip for mobile devices, which supports 32-bit/768 kHz source code output and high-specification 11.2MHz DSD files. Represents action.

ES9018K2M chip

　　　　The ES9018K2M chip has a dynamic range of 127dB, which can fully display the details of music. The ultra-low distortion of -120dB THD+N can better restore the essence of music.

　　　　Equipped with ES9038Q2M and three OPA1622 operational amplifiers, it has a dynamic range of 129dB and a distortion of -120dB, and supports DSD hardware decoding.

ACS43L36 decoding and ear amplifier integrated chip

　　　　Of course, in addition to these two chips, CirrusLogic decoding and amp integrated chip CS43L36 has also appeared on Meizu’s PRO 6, and basically all the audio parts involved in PRO 6 are controlled by it.

　　　　Although HiFi mobile phone is equipped with professional audio chip, it has a certain gap with high-quality walkman in terms of resolution, dynamic response and thrust. The reason is that the power supply scale, decoding chip specifications and the number of operational amplifiers are not as good as the latter. For example, the ES9018K2M mentioned just now is actually a scaled-down version of ES9018, which is a low-power version specially customized for mobile devices. The former is dual-channel and the latter is 8-channel. Whether it is dynamic range or signal-to-noise ratio, ES9018 is far better than ES9018K2M. The main reason why enthusiasts don’t want to use mobile phones to listen to high-quality headphones is because of the thrust of mobile phones on headphones, and they can’t give full play to good headphones.

In which direction will HiFi develop?

　　　　At present, limited by the circuit structure and power supply of mobile phones, there is still a long way to go to equalize the sound quality of professional equipment. Of course, we do not rule out the possibility of improving the battery technology of mobile phones, further optimizing the circuit design, and further controlling the heat and power consumption by high-quality audio chips, but it will be difficult to achieve it for a while.

It is also beneficial to integrate the decoding operational amplifier into the earphone.

　　　　In addition, mobile phones are gradually developing towards thinness, and the contradiction between battery capacity and chip power consumption is increasingly prominent, and there are signs of canceling the 3.5mm headphone jack in a large area. The most typical is the series of mobile phones. The 3.5mm earphone interface is cancelled, and the Lightning data interface can only output digital signals, and the decoding and operational amplifier will be integrated into the earphone. Although the high-end audio circuit can be used without signal interference compared with mobile phones to further reduce the noise floor, the power consumption of headphones is serious, and the high-integration decoding and operational amplifier will damage the sound quality output to some extent, and unreasonable circuit design will also produce certain noise floor.

Active noise reduction principle

　　　　Fortunately, there are still many remedies for mobile phone HiFi. For example, better audio technology is adopted at the earphone end. For example, 1MORE’s Tiinlab A2 exclusive active noise reduction chip can adjust the frequency band for noise reduction with broadband EQ as a supplement, and at the same time, it has a very good adaptability, such as Lightning and USB Type C digital interface. Thanks to the self-planned Tiinlab A2 exclusive active noise reduction chip, 1MORE full-time noise reduction technology achieves a perfect balance between noise reduction effect and sound quality. Tiinlab A2 is in the range of 50-2000Hz, which has covered most business and life frequency bands, which is wider than the frequency band where most noise-reducing headphones are only concentrated within 1000Hz, but at the same time, the noise reduction depth is controlled, and the inhalation feeling will not be too strong.

　Intelligent sonar earphone

　　　　Another interesting thing is HTC’s HTC USonic smart sonar headset. This earphone uses sonar to sense the cochlear structure, feeds back the signal to the mobile phone, makes custom adjustment according to the specific shape of each ear, and then outputs lossless timbre through USB-C interface, providing a good audio experience.

MDR-XB950BT Bluetooth Headset

　　　　At the beginning of this article, we mentioned that one plus five supports aptX & aptX HD HD music transmission. Undoubtedly, wireless Bluetooth will also be one of the solutions for future mobile phone HiFi. At present, the main quality standards of Bluetooth audio coding are SBC, AAC, aptX and LDAC from low to high. SBC has the best compatibility and the worst sound quality. AAC is relatively better. If the mobile phone plays AAC audio files, then using AAC Bluetooth coding transmission can save a coding conversion step, and the sound quality is more fidelity, but the gap is not small. AptX is a higher Bluetooth audio coding, and aptX-HD can achieve near lossless sound quality. LDAC is a Bluetooth audio coding promoted by Sony, which can achieve -Res lossless audio transmission and has the best sound quality. However, apart from Sony’s own equipment, there are not many supporting this coding at present, but it is the future development direction.

Write it at the end

　　　　After reading the above contents, I believe everyone has a certain understanding of audio and mobile phone HiFi. Although these are only nine Niu Yi hairs in the audio industry, after understanding these, we can roughly understand what level of mobile phone HiFi is promoted by mobile phone manufacturers, and we can also have some basic knowledge support when choosing headphones. Of course, it should be kept in mind that even when purchasing headphones for HiFi mobile phones, you can’t just look at the price. After all, the thrust of mobile phones is limited, and different headphones have different styles. The right combination of front and rear ends is the best choice.

People’s Financial News On May 26th, Enterprise Search APP showed that Midea (Foshan Nanhai) E-Commerce Co., Ltd. was recently established with a registered capital of 10 million yuan, and its business scope includes: sales of smart home consumer equipment; Sales of semiconductor lighting devices; Artificial intelligence hardware sales; Household appliances installation services, etc. Enterprise investigation shows that the company is indirectly wholly-owned by Midea Group.

　　Multi-departments jointly issued a document: all localities should implement the "health code" national mutual recognition and one code communication.

　　On December 10th, 2020, National Health Commission, National Medical Insurance Bureau and state administration of traditional chinese medicine jointly issued the Notice on Further Promoting the "Internet+Medical Health" and "Five Ones" Service Action.It is clearly required that all localities implement the national mutual recognition of "health codes" and use one code to communicate..

　　The notice of action requires that all localities should rely on the national integrated government service platform to implement the mutual recognition mechanism and rules of "health code" information, make it clear that the "health code" information of cross-regional migrants is credible and available in all regions, effectively facilitate people’s travel and cross-provincial mobility, and realize unified policies, unified standards, national mutual recognition and one-code communication for epidemic prevention.

　　In low-risk areas, the action notice is clear, except for special places and special personnel, the "health code" should generally not be checked.

　　For the elderly and other groups who don’t use or operate smart phones, the notice of action requires that alternative measures such as reading ID cards, showing paper certificates, handling by relatives and friends, or binding multi-person epidemic prevention "health codes" by one person can be taken. Medical institutions at or above the second level should set up a "no health code" green channel at the entrance, equip personnel to help inquire about the epidemic prevention "health code", assist in filling in the epidemiological history survey by hand, shorten the waiting time, and provide more detailed and appropriate services for the elderly and other groups.

　　In addition, for the standardized use of epidemic prevention "health code" data, the action notice emphasizes the need to strengthen data security management and effectively protect personal privacy.

　　Original attached notice:

　　About further promotionNotice of "Internet+Medical Health" and "Five Ones" Service Action

　　National Health Planning No.22 [2020].

　　All provinces, autonomous regions, municipalities directly under the Central Government and Xinjiang Production and Construction Corps Health and Wellness Committee, Medical Insurance Bureau, Administration of Traditional Chinese Medicine, various departments of the commission (bureau) organs, directly affiliated units and contact units of the commission (bureau), and the commission (bureau) is a (hospital):

　　Since the issuance of the document "Opinions of the General Office of the State Council on Promoting the Development of" Internet+Medical Health "(Guo Ban Fa [2018] No.26), all localities have acted quickly and implemented innovation, which has achieved remarkable results in promoting the development of" Internet+Medical Health "and formed a good trend of departmental coordination and linkage. Especially during the epidemic prevention and control period, innovative online service modes in various places have played an important role in supporting accurate epidemic prevention and control, avoiding cross-infection, promoting the orderly flow of personnel and returning to work and production. In order to summarize the typical practices emerging in the promotion practice, further focus on the "urgent difficulties and worries" of people seeking medical treatment, and continue to promote the in-depth development of the "Internet+medical health" service for the convenience and benefit of the people, the National Health and Wellness Commission, the National Medical Insurance Bureau and the State Administration of Traditional Chinese Medicine decided to deepen the "five ones" service action in the whole industry. The relevant matters are hereby notified as follows:

　　First, promote "integrated" shared services and improve the level of convenient, intelligent and humanized services.

　　1. Adhere to the integration of online and offline. Medical institutions should make full use of information technologies such as the Internet and big data to expand service space and content while continuously improving offline medical services, actively provide patients with convenient and efficient online services, follow-up management and remote guidance, and gradually realize patients’ home rehabilitation. Internet hospitals should realize data sharing and business collaboration with physical medical institutions that rely on offline, and provide continuous services that seamlessly connect online and offline. Encourage all localities to use intelligent IOT terminal equipment to carry out monitoring, tracking and management of characteristic index data of patients with chronic diseases and high-risk groups, and sink health management to community service sites in combination with family doctors’ contract service. Promote Internet diagnosis and treatment services, give full play to the role of Internet hospitals in primary medical services, guide the downward shift of focus and sinking of resources, and promote graded diagnosis and treatment in an orderly manner. In view of the "digital divide" obstacles existing in the elderly, children, disabled people and other groups, all localities should adhere to the practice of walking on two legs and reasonably retain the traditional service methods, so as to realize the convenience of online services and pay attention to the humanization of offline services. On the basis of implementing non-emergency appointment diagnosis and treatment, medical institutions should simplify the online service process, improve various appointment registration methods such as telephone, internet and on-site, unblock the channels for family members, relatives and friends, family doctors, etc., and provide a certain proportion of on-site number sources, keep manual service windows such as registration, payment, printing inspection results, and provide medical guidance services with medical guides, volunteers, social workers and other personnel.Effectively solve the practical difficulties of the elderly and other groups in using intelligent technology.

　　2. Optimize the smart medical service process. All localities should adhere to the patient-centered principle, actively implement the requirements of the Notice of the National Health and Wellness Commission and the State Administration of Traditional Chinese Medicine on Deepening the Activities of "Internet+Medical Health" to Facilitate and Benefit the People (Guo Wei Planning and Development [2018] No.22), and continue to promote 30 measures for 10 services to facilitate and benefit the people. According to the Notice on Further Improving the Appointment Diagnosis and Treatment System and Strengthening the Construction of Smart Hospitals (Guo Wei Ban Yi Han [2020] No.405), hospitals above the second level should accelerate the integration of internal information systems and business collaboration, optimize the medical treatment process and improve service efficiency. Gradually realize online health consultation, follow-up, prescription review, medication guidance, psychological and health status assessment, vaccination appointment and electronic prescription circulation, drug distribution, follow-up, home ECG monitoring, community appointment referral and other contents. Medical associations and medical communities should strengthen the integration of medical and health services, support service communication with information communication, and guide patients to seek medical treatment in an orderly and convenient manner.

　　3. Promote regional information sharing and mutual recognition. All localities should adhere to the problem-oriented and demand-oriented, strengthen the promotion and application of the functional guidelines and data standards of the national health information platform and hospital information platform in the province as a whole, promote the standardized access of health information platforms of medical institutions at all levels and provincial traditional Chinese medicine museums to the province as a whole, and continuously improve the quality of data connectivity with national platforms. Under the premise of medical quality control and informed consent of patients, we will promote the access and sharing of medical health information such as electronic medical records, inspection results and medical imaging materials among medical institutions, and gradually realize mutual recognition of information covering provinces. All localities should speed up the linkage between electronic health records, electronic medical records and public health service information, promote online inquiry and standardized use of electronic health records on the basis of ensuring data security and personal privacy, clarify the open content and unify the open path, and gradually realize residents’ own or authorized convenient access to personal electronic health records, so as to better record and manage the health information of residents throughout their life cycle. The state will launch relevant pilot projects in a timely manner, actively promote the development of regional integrated information connectivity, mutual recognition and sharing services in areas with conditions such as Beijing-Tianjin-Hebei, Yangtze River Delta and Chengdu-Chongqing.

　　Two, promote the integration of "one code" service, and break the information barrier of multi-code coexistence and mutual incompatibility.

　　4. Strengthen the "one code for all" in the industry. All localities should, in accordance with the unified technical standards formulated and promulgated by the state, accelerate the application of residents’ electronic health codes, and focus on solving the problem of "one hospital, one card, and mutual incompatibility" in medical and health services. Encourage all localities to popularize the application of residents’ electronic health codes as a starting point, promote medical treatment in real-name registration system, explore the use of ID numbers as the main index and other ID numbers as a supplement, and strengthen the management of residents’ health identity identification and use. Promote residents’ electronic health codes to replace medical and health institutions’ medical cards, expand their use in the fields of diagnosis and treatment services, public health services, chronic disease management, online information inquiry, health education, blood management, etc., and gradually realize the universal use of one code in the health industry. For the elderly, children and other groups, it is necessary to reasonably retain offline manual services and effectively solve the obstacles of intelligent technology.

　　5. Promote cross-departmental "multi-code integration". All localities should adhere to the people-oriented principle, strengthen the transformation and docking of business information systems of relevant medical institutions, strengthen the coordination among departments, promote the "multi-code integration" application of residents’ electronic health codes, financial payment codes, citizen cards, etc., and strengthen information exchange and business communication on the basis that the "cards" and "codes" of different departments can be switched, so as to facilitate people’s use. Encourage all localities to explore the use of a unified "Internet+medical health" service portal, promote the effective integration and application of residents’ electronic health records and electronic medical records, and provide residents with life-cycle health management services. At the same time, through the retrospective management of "multi-code integration", the effective supervision of medical treatment records, expense lists, electronic prescriptions, electronic medical records and medical expense settlement records will be gradually realized in the "three-medical linkage".

　　6. Realize "one code for all lines" of health codes. All localities should rely on the national integrated government service platform, implement the mutual recognition mechanism and rules of health code information, make clear that the health code information of cross-regional migrant workers is credible and available in all regions, effectively facilitate the travel and cross-provincial mobility of personnel, and realize the unified policy, unified standard, national mutual recognition and one-code communication of epidemic prevention health codes. In low-risk areas, except for special places and special personnel, health codes should generally not be checked. For the elderly and other groups who don’t use or operate smart phones, alternative measures can be taken, such as reading identity cards, showing paper certificates, handling by relatives and friends, or binding multi-person epidemic prevention health codes by one person. Strengthen the standardized use of epidemic prevention health code data, strengthen data security management, and effectively protect personal privacy. Medical institutions at or above the second level should set up a green channel without health code at the entrance, equip personnel to help inquire about epidemic prevention health code, assist in completing epidemiological history investigation by hand, shorten the waiting time, and provide more detailed and appropriate services for the elderly and other groups.

　　Three, promote the "one-stop" settlement service, improve the "internet plus" medical online payment.

　　7. Implement "one-stop" timely settlement. Medical and health institutions should optimize the online and offline payment process, improve the settlement mode and solve the payment blocking problem through self-service machines, online services and mobile terminals. On the premise of ensuring information security, we will strengthen cooperation with medical insurance, commercial insurance, UnionPay and third-party payment institutions to provide patients with a variety of online payment methods. Accelerate the docking of relevant information systems and data sharing, expand online payment functions, promote "one-stop" timely settlement, and provide more convenient services for insured personnel.

　　8. Implement the "internet plus" payment policy. Implement the National Medical Insurance Bureau’s Guiding Opinions on Actively Promoting the Medical Insurance Payment of internet plus Medical Services (No.45 [2020] of Medical Insurance), adhere to the consistency between online and offline, implement a fair medical insurance policy for online and offline medical services, and maintain a balanced level of treatment. The consultation fees and drug fees incurred by the insured in the designated medical institutions for medical services in internet plus as a whole can be paid in accordance with the provisions on medical insurance in the whole area. All localities can gradually expand the scope of medical insurance payment for "internet plus" medical services for common diseases and chronic diseases from outpatient chronic diseases. Support the circulation of "internet plus" medical referral prescriptions, and explore the interconnection of prescription information purchased by designated medical institutions and designated retail pharmacies. Combined with the pilot project of direct settlement of outpatient expenses, we explored the direct settlement of "internet plus" medical services in different places. Implement the medical insurance reimbursement policy of "long-term prescription", and realize online medical insurance settlement for online prescription drug fees of "internet plus" medical services that meet the requirements.

　　Four, to promote the "one network" government services, to resolve the difficult, slow and complicated problems.

　　9. Expand government sharing services. To implement the State Council’s requirement of strengthening the orderly sharing of government information, the health industry has already shared data such as birth medical certificate, death certificate, population information, doctor’s practice registration information, nurse’s practice registration information, medical institution’s practice registration information, etc., and a new batch of data sharing lists, such as nucleic acid detection information, have been formulated and issued at the national level, so as to improve the coordination mechanism of data sharing and support the cross-departmental and cross-level handling of government services. All localities should complete the inter-provincial communication of government services such as "filing of free clinic activities" and "filing of disinfection products health and safety evaluation report". Accelerate the docking of the provincial overall regional national health information platform with the government information service platforms at all levels, and promote the government service matters to the best of their ability. Promote the convenience service mode such as "one thing for birth", and realize "one submission, multi-certificate joint office, one stop delivery" for birth medical certificate, vaccination, household registration, medical insurance participation, social security application and other matters.

　　10. Convenient information inquiry service. All localities should rely on the official website, WeChat official account, regional national health information platform or government service platform, etc., and integrate and publish online mobile service applications related to "Internet+medical health" in the province, so as to facilitate the public to obtain authoritative information such as diagnosis and treatment services and health management services in one channel.

All localities should rely on the national and provincial overall regional national health information platforms to realize cross-level sharing of information such as population death registration data, legal infectious disease report data, public health emergency report data, nucleic acid detection data and antibody detection data between national and provincial platforms. Encourage all localities to apply electronic health records in various assessments and gradually cancel paper files. Encourage the development of a unified data collection information system for primary medical and health institutions based on the province. Grassroots reports should be automatically generated through the information system as far as possible, reducing manual reporting and paper reports, and gradually realizing "recording only once" for primary data collection.

　　Five, promote the "chess game" anti-epidemic service, strengthen the information technology support for the prevention and control of normalized epidemic situation.

Strengthen the construction and application of Internet consulting service platform for overseas Chinese, and better provide health consulting services for overseas Chinese.

　　Departments in charge of health, medical insurance and Chinese medicine at all levels should adhere to the people-centered development idea, strengthen organizational leadership, and refine service measures to ensure that all tasks are put in place. It is necessary to promote the in-depth application and innovation of the new generation of information technology in the medical and health industry, further optimize the allocation of resources, improve service efficiency, strengthen online supervision, and strengthen security. We must adhere to the principle of encouraging innovation, inclusiveness and prudence, support the "Internet+medical health" demonstration provinces (autonomous regions and municipalities) to try first in combination with the actual situation, explore new modes of innovative medical and health services, and enhance the people’s sense of access to medical treatment. At the national level, work guidance and inspection will be strengthened, and a number of typical experiences and practices of the "Five Ones" action will be selected and promoted in a timely manner to continuously promote the effectiveness of the "Internet+medical health" service for the convenience and benefit of the people.

　　As the third Belt and Road International Cooperation Summit Forum was held in Beijing, China officially released the Global Initiative on Artificial Intelligence Governance (hereinafter referred to as the Initiative). The launch of the Initiative fully reflects China’s responsible attitude, leading spirit and mission under the guidance of the concepts of "Community of Human Destiny" and "Community of Cyberspace Destiny" of the Supreme Leader and Chairman, and in the face of a new wave of global scientific and technological revolution symbolized by artificial intelligence and other technologies. It is an important measure for China to conform to the development trend of network and informatization, respond to the demands of developing countries and respond to the calls of the international community for effective governance of new technologies in the process of cyberspace international governance.

　　Cyberspace is not a virtual space, but a projection and manifestation of the real world. Judging from the international situation, the relations between major powers, international order, regional security, social thoughts and global governance are undergoing profound adjustments. Coupled with the impact of a century-old epidemic, the world has entered a "great change that has never happened in a century." From the development process of global informatization, artificial intelligence, quantum technology, blockchain and other technologies have developed rapidly, and the outline of a new round of scientific and technological revolution has gradually become clear. The new technology with the characteristics of intelligence, digitalization, informationization and virtualization not only profoundly affects the domestic industrial form, lifestyle and social form of each country, but also brings about the comparative change of power between countries and intensifies national competition. The security and interests of the country, the operation of enterprises, and the human rights and privacy of citizens are all concentrated in cyberspace as never before, and the data flows endlessly. Multilateral parties in the international community, whether governments, enterprises, communities or people, are looking forward to the gradual establishment of the cyberspace once known as the "wild west", forming a code of conduct and realizing global governance.

　　Artificial intelligence is not a castle in the air, but a simulation and extension of human brain thinking mode. It is regarded as one of the landmark technologies of this round of scientific and technological revolution, and has accelerated its development in recent years, showing new features such as deep learning, cross-border integration, man-machine collaboration, open intelligence and independent control. In daily life, people have applied artificial intelligence technology in all aspects, such as personalized recommendation system for online shopping, face recognition, artificial intelligence medical image recognition, artificial intelligence navigation, intelligent writing assistant and voice assistant, etc., and its various applications are as bright as the sea of stars. However, concerns about its safety and risks are unprecedented. People from all walks of life are generally worried that its risks and threats will not only lead to legal and ethical risks, but also lead to security threats in major fields such as society, economy and military affairs. General Secretary of the Supreme Leader pointed out: "New technologies such as artificial intelligence and virtual reality are changing with each passing day, and the combination of virtual economy and real economy will bring revolutionary changes to people’s production methods and lifestyles. This change will not happen overnight, nor will it be smooth sailing. It needs the joint efforts of all countries to fully amplify and accelerate its positive effects while minimizing possible negative effects. " The Chairman of the Supreme Leader advocates that China supports strengthening dialogue around artificial intelligence, and proposes to hold a special meeting in due course to promote the implementation of the principles of the G-20 artificial intelligence and lead the healthy development of global artificial intelligence. General Secretary of the Supreme Leader further pointed out that,"Technology is a sharp weapon for development, and it may also become the source of risks. It is necessary to look forward to the rule conflicts, social risks and ethical challenges brought about by the development of science and technology." A series of instructions from the Supreme Leader General Secretary pointed out the direction for China to participate in and lead the global artificial intelligence governance process.

　　In recent years, the international community has put forward some important initiatives to promote the healthy development of artificial intelligence. In 2019, UNESCO issued the Proposal on Ethical Issues of Artificial Intelligence, calling on governments, enterprises, social organizations and individuals of all countries to actively consider the ethical issues of artificial intelligence in the research and development, application and governance of artificial intelligence technology, and promote the global dissemination and implementation of ethical principles of artificial intelligence. G20 Group emphasized the ethical and social responsibility of artificial intelligence in the G20 Principles of Artificial Intelligence released in 2019, and encouraged countries to take ethical and responsible measures in the research, development, application and governance of artificial intelligence technology, and strengthen global governance cooperation to jointly promote the healthy development of artificial intelligence. In 2018, the European Commission put forward the Code of Ethics for Artificial Intelligence, which emphasized that the application of artificial intelligence must conform to human values and ethical principles, and suggested taking measures to strengthen the supervision and transparency of artificial intelligence and promote the sustainable development of artificial intelligence technology. Some non-governmental organizations have also put forward ethical norms and norms of artificial intelligence, emphasizing that artificial intelligence technology should serve human welfare rather than replace human beings, and promote the inclusiveness and sustainability of artificial intelligence technology. Generally speaking, the international community has realized the impact and challenges of artificial intelligence technology on society and human beings, so it advocates governments, enterprises and social organizations to actively think about the ethical and social responsibilities of artificial intelligence and take measures that meet ethical requirements to promote the healthy development of artificial intelligence technology.

　　There are similarities, emphases and differences in the artificial intelligence governance concepts of multilateral parties in the international community. China’s mission in this era is how to implement the instructions of the Supreme Leader General Secretary, conform to the development trend of global technology and industrial revolution, give consideration to the two major tasks of safety and development, seek common ground while reserving differences with all parties in the world based on his own governance practice, form an attractive Chinese plan, contribute to the international governance of artificial intelligence, and create a good internal and external environment for international cooperation in the field of artificial intelligence.

　　In September 2021, the National Professional Committee for the Governance of New Generation Artificial Intelligence issued the "Ethical Code of New Generation Artificial Intelligence"; In December 2021, China issued the "Position Paper on Standardizing Military Applications of Artificial Intelligence"; On November 16th, 2022, China submitted China’s Position Paper on Strengthening the Ethical Governance of Artificial Intelligence to the United Nations General Assembly. China put forward the concept of common, comprehensive, cooperative and sustainable global security in regulating artificial intelligence, and advocated all countries to actively seek consensus and practice the concept of building a community of human destiny in the field of artificial intelligence. These concepts, principles, and documents have made an attempt to solve the problem of artificial intelligence governance. The "Initiative" launched by China this time not only embodies these ideas, principles and documents, but also absorbs the outstanding achievements of multilateral parties in the international community, including developing countries, in the field of artificial intelligence governance in recent years.

　　In the introduction at the beginning, the Initiative highly affirmed the rapid development, far-reaching influence and great opportunities brought to the world by artificial intelligence technology. At the same time, it also points out all kinds of risk challenges brought by this technology, and puts the key and significant issue of artificial intelligence governance related to the fate of all mankind in front of the world. The introduction puts forward the security concept, principles and mechanisms that all countries should uphold in the process of artificial intelligence governance, and highlights China’s consistent cooperative position in cyberspace, as well as the idea of promoting artificial intelligence governance together with various actors in cyberspace with an open attitude. Based on the technical attributes of artificial intelligence, China put forward development suggestions to continuously improve the safety, reliability, controllability and fairness of artificial intelligence technology.

　　The contents of the "Initiative" total eleven articles, which comprehensively, systematically and scientifically expounded China’s position and proposition from three levels: security, development and governance. These clauses not only respond to the general concerns and concerns of the international community, especially the developing countries, but also show China’s profound understanding of artificial intelligence governance. The first article of the Initiative puts forward that the development of artificial intelligence should adhere to the concept of "people-oriented", which is intended to warn that the development of technology cannot deviate from the direction of human civilization and progress. Article 2 proposes that when providing artificial intelligence products and services to other countries, we should respect the sovereignty of other countries, strictly abide by the laws of other countries, and oppose the use of artificial intelligence technology to interfere in other countries’ internal affairs, which fully takes into account the demands of developing countries that the development of artificial intelligence technology will pose a threat to their national security and sovereignty. For example, some countries have been worried that artificial intelligence technology will be used for military purposes, thus posing a threat to international peace and stability; In addition, some countries worry that artificial intelligence technology will be used to manipulate elections, disrupt financial markets and create social divisions, which will have a negative impact on social stability. The third article puts forward that the development of artificial intelligence should adhere to the purpose of "intelligence is good", which is not only a supplement to the last article, but also the common wish of many artificial intelligence developers and practitioners. Article 4 puts forward that all countries have the equal right to develop and use artificial intelligence, aiming at avoiding and eliminating the new digital divide caused by artificial intelligence.Oppose countries with corresponding technological advantages to use artificial intelligence to suppress, contain and block the development of artificial intelligence in other countries, and block and interfere with the development of artificial intelligence in the world. In the following items, the Initiative comprehensively shows that China is open and fair with the international community in the field of artificial intelligence governance from the aspects of testing and evaluating the risk level of artificial intelligence, establishing and improving relevant laws and regulations, adhering to the principles of fairness and non-discrimination, putting ethics first, actively developing the development and application of related technologies for artificial intelligence governance, and persisting in dialogue and cooperation, extensive participation, consensus and gradual progress, and promoting multi-stakeholders to form a broad consensus in the field of artificial intelligence governance.

　　At the end, the Initiative specifically calls for enhancing the representation and voice of developing countries in the global governance of artificial intelligence. Seeing this, and then connecting with the third "One Belt, One Road" international cooperation summit forum being held in Beijing, the vast number of developing countries gathered in Beijing, eager to catch the express train developed by China, hoping to hear the voice of China, including the hope that China will speak for the vast number of developing countries on the major issue of artificial intelligence governance in the current international community. China is an active promoter and practitioner of international governance of cyberspace. In 2015, the Chairman of the Supreme Leader put forward the concept of "building a community of destiny in cyberspace" for the first time in the second world internet conference, and deeply explained the "four principles" and "five propositions" of Internet development and governance, which attracted wide attention from the international community. Today, the launch of the Initiative once again reflects China’s determination to implement the concept of "Building a Community of Cyberspace Destiny" by Chairman of the Supreme Leader, its image and mission as a responsible big country in cyberspace, and its unremitting efforts to practice fairness and justice in the process of international governance in cyberspace.

　　At present, there are three key words in the process of international governance of cyberspace, namely peace, security and development. In the field of artificial intelligence governance, the three themes have not changed fundamentally: first, the basic principles of artificial intelligence governance concept are the common values of equality, fairness and justice, sharing and governance, or the jungle law of the jungle; The second is the basic attitude towards artificial intelligence governance, whether it is laissez-faire or legal supervision on the basis of respecting the network sovereignty of various countries; The third is the basic position on artificial intelligence governance, whether it is used as a means to benefit mankind and maintain peace and stability, or as a deterrent, preemptive, or even as a tool to interfere in other countries’ internal affairs, create conflicts or even wage war. The development of artificial intelligence technology has aggravated the complexity of human security. In this new field, competition between countries is intensifying, government governance is being impacted, and social structure has undergone tremendous changes. How to deal with it, the international community needs new wisdom, new thinking and new paths.

　　Let the light of reason and wisdom light up the starry sea of artificial intelligence. It is predicted that in the future, China will continue to unite all multilateral parties in the international community, especially the developing countries, and continue to launch the best practice cases and specific road maps for artificial intelligence governance around the concept of "building a community of cyberspace destiny" with the launch of this Initiative as a new starting point. This is not only the mission of China, but also the demand of developing countries, a concrete action to follow the law of cyberspace development, and an inevitable choice for human beings to meet the era of artificial intelligence.

Original Lu Pengpeng Blue Whale News

Blue whale reporter Lu Pengpeng

On Saturday morning, Lei Jun, a model worker, took a group of senior executives to start the live broadcast in Shanghai. During this period, Lei Jun not only responded to the "Singer" rocking incident, but also encountered a malicious car. The three and a half-hour live broadcast revealed a lot of information.

What happened to Lei Jun’s live test drive for 3 hours?

In this live broadcast, Xiaomi SU7 Pro model was officially unveiled, and Lei Jun drove the vehicle from century avenue to Mengma Town in Hangzhou for the delivery ceremony.

Lei Jun’s live broadcast is mainly to show the NOA (automatic assisted navigation and driving) function of Xiaomi city. With the help of Xiaomi intelligent driving system, how vehicles can intelligently respond to various road conditions. At the same time, it will also test the real battery life and real energy consumption performance of Xiaomi SU7 Pro.

1. The intelligent driving scheme is self-developed by Xiaomi, and the annual cost exceeds 2 billion yuan.

First of all, when talking about the smart driving scheme, Lei Jun said frankly: "The annual cost of developing smart driving by Xiaomi itself is more than 2 billion yuan, and the investment is extremely high. There are few manufacturers in China who have researched it from beginning to end."

When asked, "There have been rumors that Xiaomi’s vision intelligent driving scheme will be carried out by cooperation or third-party bidding in the future", Lei Jun personally blamed: "We set a goal from the beginning, and all the intelligent driving of Xiaomi should be developed by ourselves."

In addition, Lei Jun also shared Xiaomi’s team building in the field of intelligent driving. He mentioned that Xiaomi Auto’s intelligent driving team has more than 1,000 engineers.

Lei Jun said that companies such as Huawei and Weixiaoli are very determined to invest in intelligent driving, especially in Xpeng Motors. Lei Jun himself is closely related to He Xiaopeng and an early investor in Xpeng Motors.

2. Encountered a malicious car at high speed and almost had an accident.

Despite NOA’s blessing, Lei Jun still encountered some uncivilized driving by car owners. The Blue Whale reporter noticed that a white car suddenly accelerated and maliciously changed lanes during high-speed driving, which almost caused an accident and did not turn on the turn signal.

Lei Jun said that this driving style is very dangerous and called "I want to report him".

3. Lei Jun responded to the singer’s shaking: I just want to do my best to make Xiaomi well.

In the live broadcast, Lei Jun also responded to the singer’s rocking incident, saying: "Many colleagues discussed this yesterday, but I haven’t figured out what it is yet. Thank you for your support, and now I still try my best to do a good job in Xiaomi. " Recently, Lei Jun climbed to the top of Singer 2024, beating Han Hong, Phoenix Legend, Jay Chou, Jacky Cheung, etc., and gained the support of a large number of netizens.

Finally, after three hours’ journey, Lei Jun and his entourage arrived in Mengma Automobile Town, Hangzhou, and ended the live broadcast after the car delivery ceremony.

4. Fans are crazy about giving gifts, and they occupy the list in the old age.

It is worth noting that during the last live broadcast, Lei Jun did not turn on the reward function and was squandered by fans. At that time, Lei Jun responded: "I am not rejecting it, but I am worried that everyone will brush too much, and the live broadcast room will be more chaotic. Why don’t I consider opening presents or something next time? In fact, I think it’s good to receive some gifts from everyone. "

Today, Lei Jun fulfilled his promise to open a gift reward, and the whole gift was screened in the live broadcast room. Vanke Eslite CEO Chennian even brushed several carnivals, becoming Lei Jun’s "big brother on the list", and the second user on the list was the official flagship store of Vanke Eslite.

Lei Jun said that when he went back, he would count the amount of gifts received and replace them with millet products as welfare products for fans in the next live broadcast.

According to archaeological data, the cumulative number of viewers of this live broadcast exceeded 27 million, the number of online users at the peak was as high as 4.8 million, and the Lei Jun account added 360,000 powder.

De-intermediation of enterprise communication

Bosses get together to be online celebrity.

Lei Jun’s last live broadcast was in April. The number of viewers exceeded 100,000 in just one minute, and the number of viewers in two minutes was over 10 million.

In the live broadcast, he responded to a series of questions, such as "the cool man, there is no cold 4 billion in Cary, imitating Musk", and related topics once dominated the hot search in Weibo.

As a "model worker in Zhongguancun", Lei Jun has always been active in the front line of new media when the first generation of Internet tycoons gradually retired from the rivers and lakes, and his output of vibrato audio and video is an average of two per day. Lei Jun showed entrepreneurs what is the real "top flow".

Blue Whale reporter found that not only Lei Jun himself, but also many senior executives of Xiaomi Company personally went off to build online celebrity IP.

For example, Lu Weibing, president of Xiaomi Group, settled in Tik Tok in February this year, Xu Fei, CMO of Xiaomi Group, settled in Tik Tok in March this year, and Wang Teng, general manager of Redmi brand, settled in Tik Tok in March this year.

During the period from February to May, Xiaomi executives released as many as 40 or 50 videos, almost maintaining the frequency of the day.

After Lei Jun started the first shot of "de-intermediation" of corporate public relations communication, the trend of learning Lei Jun spread from the automobile circle to the whole Internet circle.

For example, 360 Zhou Hongyi, Weilai Li Bin, Gree Dong Mingzhu, etc. Recently, even Jia Yueting, who is far away from the other side of the ocean, has started to do self-media. He said that he would start the commercialization of personal IP, make some money as soon as possible, partly pay off debts and partly supplement the company to build cars, and strive to support the basic operation of FF.

Can the boss get together and "roll" into the live broadcast room, saving hundreds of millions of advertising fees? This seems to be a very cost-effective deal, but it is not easy to do it. Whether it can create a successful network red IP varies from person to person.

After all, the bosses personally leave the scene, facing the quality inspection of the whole network. The true expression may win the crowd of netizens, but people will always talk too much and lose too much. Once the opinions are controversial, the effect will be counterproductive. As Lei Jun said in the live broadcast today: "I thought the live broadcast was to get a mobile phone to talk to the camera, but it was far from simple."

Original title: "Lei Jun drives 20 million people to watch live: being maliciously driven, responding to" Singer "and shaking people, and rewarding old people with crazy gifts"

　　Cctv news(Reporter Xiong Yunyun) Shuttle through the "First Street of Jiangxi Culture" — — Nanchang Wanshou Palace historical and cultural block, with stone streets criss-crossing, brick by brick, one scene at a time, blue-gray and Jiangxi-style residential antique buildings row upon row, and the small shops in the winding lanes are full of strong humanistic and commercial atmosphere, and a picture of "Old Nanchang" that has passed through the Millennium is slowly unfolding here.

　　Wanshou Palace historical and cultural block is located in the core business district of Nanchang Old Town. At the beginning of the 20th century, Wanshou Palace was the Wangpu block in Nanchang, where porcelain, grass cloth, silk, spices and seafood came in and out, promoting it to become a bustling downtown integrating business culture, Taoist culture and street culture.

　　During the Spring Festival, dragon and lion dances, Spring Festival market, blessing performances, food and new year market and other activities were staged in the historical and cultural block of Wanshou Palace, and the streets were decorated with lights and jubilant, where traditional culture and fashion consumption collided with new sparks.

　　It is understood that from the New Year’s Eve to the fourth day, the total passenger flow in the historical and cultural block of Wanshou Palace in five days exceeded 500,000, an increase of 50% over the same period last year. The strong recovery of the consumer market during the Spring Festival not only makes the "taste of the year" gradually spread, but also makes the power of economic recovery stronger and stronger.

　　At the beginning of the new year, Jiangxi Branch of CCB strives for perfection in the construction of various scenes such as "food, housing, transportation, entertainment, car, shopping, and life service", undertakes the issuance of consumer vouchers by many local governments in Jiangxi Province, gathers strength to "revitalize the city by festivals", and relies on the major business districts in the province such as the historical and cultural block of Wanshou Palace to focus on the two cores of "supply side+consumption side" to drive holiday consumption. The activities focused on sectors such as "Aishang buys Anyi in winter", "Happy Life in Tesco Bay" and "Celebrating the Spring Festival and Buying Qingshan Lake". Relying on the cultural and tourism consumption gathering area, the consumption scenes such as "night shopping", "night entertainment", "night tour" and "night health" were upgraded, further enriching the convenience consumption format, and expanding and upgrading the whole field to stimulate new consumption momentum. In January 2023 alone, Jiangxi Branch of CCB received a total of 100 million yuan of government coupons, which activated the "two-end vitality" of the supply side and the demand side, and promoted the consumption to pick up and run out of acceleration.

　　Recently, it was revealed that the relevant departments issued a new regulation on webcasting dramas: from now until June, all online dramas, TV dramas and online movies with costume themes, including martial arts, fantasy, history, myth, crossing, biography and palace fighting, are not allowed to be broadcast. Remove all the pages that have been broadcast, and arrange all the ones that have not been broadcast another day. Under the new regulations, many costume dramas, such as The Legend of the New White Snake, A Letter from the Pillow of Sansheng Sanshi and Joy of Life, will be affected.

　　However, the reporter found that although many people in the industry affirmed this trend. But up to now, the website of the State Administration of Radio, Film and Television has not issued a notice. Costume dramas such as "East Palace", "Swinging" and "Eternal Dragon Slayer" are still being updated normally on video websites.

　　Yangzi Evening News/Yangyan reporter Zhang Nan

　　"Trilogy": Transfer to Network, Offline and Backlog

　　This year, costume dramas have been broadcast, and many of them occupy the scenery. For example, the big IP adapted the screenplay "East Palace", recently won the championship of the whole network heat week, and became the online drama with the largest barrage, and also made a bunch of fans named "East Palace Girl". However, for the dramas listed in the video websites to be broadcast in 2019, such as The Longest Day In Chang’an Joy of Life’s "A Letter to the Sleeping Lady of Sansheng Sanshi", The Biography of Sun Ruowei, The Mysterious Record of Kyushu, Chang ‘an in the World, The Lonely City is Closed, and The Poems of Dasong Palace will be affected by the "ancient restrictions". Among them, Joy of Life’s six films, Biography of Imperial Concubine Sun Ruowei, Young Tales of the Song Dynasty, Doubtless Pride, Poems of the Palace of the Song Dynasty, and The Mysterious Record of Kyushu, are still costume dramas to be broadcast by five David TV stations.

　　In addition, "The Legend of the New White Snake" recently announced that it would be broadcast alone in iQiyi on March 27, and as a result, it was announced that it would be "suspended due to schedule adjustment", and the launch conference was also cancelled. The "Chang ‘an in the World", which was suspected of touching the red line, was "even worse". In 2018, it suffered two withdrawals, and the series was cut from 68 episodes to 48 episodes. The director once wrote that "I don’t even know if I change it again." With an investment cost of 500 million yuan, it is still a question whether the company can recover its capital.

　　As early as 2018, the industry was rumored that costume dramas were strictly controlled. The two great dramas, Biography of Ba Qing and Ruyi’s Royal Love in the Palace, have a bumpy fate, and the former is still overstocked. "Fire is like a Song", "Lonely World" and "Secrets of the Three Kingdoms" were also webcast. In the beginning of 2019, the online Kung Fu drama was completely banned, and the second round of Ruyi’s Royal Love in the Palace and Story of Yanxi Palace broadcast by Satellite TV was also stopped. Plays such as "Shake Up" and "My Little Girl Never Abandons" only landed in the Weekly Theater of Satellite TV.

　　Today, the "ancient order" has been upgraded again. The story of Xi Fei, which invested 60 million yuan to build a shed, was notified to stop working. Chen Qiaoen was originally invited to star in Tencent’s self-made TV series "Yanyuntai", and the contract was also cancelled.

　　The popular costume dramas "East Palace", "Swing" and "Eternal Dragon Slayer" recommended by the three major video websites have disappeared. In addition, Weibo, the original producer of "The Queen of Dugu" @ Mr. Beixi, said that "The Queen of Dugu" will be permanently offline after the finale, and then said that it will disappear completely on the 25th, which may be related to the new regulations.

　　Content and business orientation have been "severely cracked down"

　　In fact, costume dramas have many fans. What is the problem? In April 2018, Nie Chenxi, director of the State Administration of Radio and Television, clearly pointed out at the national TV drama creation planning meeting: resolutely oppose historical nihilism, arbitrarily misinterpret history, derogate and blaspheme classic traditions, and tamper with important historical events and historical figures that have reached consensus and conclusion. Fantasy, Xianxia and overhead interpretation of costume dramas can’t be made up to increase entertainment and attract attention.

　　On January 25th, the official blog of Beijing Daily published a document listing the "five sins" of Gongdou Opera, which was regarded by the industry as the clue of this wave of "ancient restrictions".

　　Specifically, the drama of the heroine, such as Biography of Sun Ruowei, the Imperial Concubine of Daming, and Old Friends of Jiangshan, which involves the struggle between the court and the court, may face deletion. However, many film and television companies have turned to the machiavellian machiavellian dramas after the heroine’s drama encountered a bottleneck in the market. However, at present, Joy of Life’s machiavellian dramas such as He Lai Hua Ting, Sword Dynasty and Your Highness the Wolf are also quite dangerous. As for the direction of historical dramas such as Chang ‘an in the World, Lonely City Closed, and Poems of the Song Dynasty Palace, it still depends on whether the plot deviates too much from history and whether the value orientation is correct. In addition, according to the analysis of the insiders, the rising copyright fees for the single episode of Gongdou drama have also led to excessive pursuit of commercial interests.

In recent years, more and more new energy vehicles have entered our sight. Whether it is the improvement of travel awareness or the helplessness of being forced to shake the number, in short, some consumers have already started to buy. Of course, one of the important reasons why new energy vehicles can enter people’s homes is the dual action of national and local subsidy policies, but in the face of these complicated policies, do you really understand them? Which "black boxes" are mixed with them, and you haven’t noticed them? Below, let’s talk together.

● "Double-decker" subsidy for new energy vehicles

If we talk about subsidies for new energy vehicles, perhaps most people know that "national+local" will give subsidies to consumers, but how much will the specific national and local governments make up? How to subsidize? Which new energy vehicles can enjoy? Maybe not many people fully understand it.

The first level: state subsidy policy.

In order to accelerate the development of the new energy vehicle industry, in September 2013, the relevant state departments issued the Notice on Continuing to Promote the Application of New Energy Vehicles, which made it clear that in 2013 -2015, consumers will continue to be subsidized to buy new energy vehicles.

First of all, the scope of subsidies is new energy vehicles that are included in the scope of central financial subsidies, and the vehicles meet the requirements (what are the requirements? The third page details) pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Secondly, the state has made it clear that the new energy subsidies given are not for car companies and dealers, but directly for consumers. When buying new energy vehicles, consumers pay after deducting subsidies from the sales price.

Finally, it should be noted that the subsidy standard is decreasing year by year. This mainly takes into account the scale effect, technological progress and other factors. According to the notice issued by the state in February 2014, the subsidy standard was reduced by 5% in 2014 and by 10% in 2015.

The second level: local government subsidies

The country takes the lead in promoting new energy vehicles, and local governments naturally need to implement them. What’s more, in the Notice on Continuing the Promotion and Application of New Energy Vehicles issued in September 2013, it has clearly pointed out the demonstration areas that hope to "respond to the call" immediately, that is, Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and other areas with heavy fine particle control tasks.

I have to say that the response of local governments is indeed fast enough. In November 2013, the first batch of new energy vehicles were promoted and applied in the list of cities or regions (what does it mean to enter the list? The third page has been released, which covers the regional cities that were previously "named" by the state. Next, the editor will take four first-tier cities in North, Shanghai, Guangzhou and Shenzhen as examples to talk about the local subsidy policy for new energy vehicles.

Beijing:

In January, 2014, the Beijing Municipal Government issued the Administrative Measures for Demonstration and Application of New Energy Passenger Cars in Beijing. The policy shows that the subsidy for purchasing new energy vehicles in Beijing is consistent with that of the state, that is, the subsidy standard is determined according to the ratio of 1:1 between the state and Beijing. However, it should be noted that the total financial subsidies of the state and Beijing do not exceed 60% of the vehicle sales price at the highest.

In addition, Beijing only subsidizes small and micro pure electric vehicles and fuel cell vehicles, and plug-in hybrid vehicles in the state subsidy policy are not among them. At the same time, only the new energy vehicles listed in the Catalogue of Recommended Vehicles for Demonstration and Application of Energy-saving and New Energy Vehicles and those listed in the Catalogue of Production Enterprises and Products of Beijing Demonstration and Application of New Energy Passenger Cars can enjoy subsidies. At present, the catalogue has not been published. Therefore, it is uncertain which new energy vehicles can be shortlisted.

In addition to price subsidies, you can buy new energy vehicles that meet the "conditions" in Beijing, and you can also shake the number in the configuration indicators of special new energy passenger cars. The results of the first lottery will be announced on February 26th, 2014. According to the data released by the Passenger Car Indicators Office, more than 1,700 applications and confirmations for extension of individual demonstration application of new energy passenger car allocation indicators have been received. According to the rough calculation of the quota and allocation ratio of passenger cars in this city this year, there will be 1,666 new energy vehicle indicators distributed to individuals in each period. Although the number of applicants in the first batch is slightly higher than the quota and needs to be shaken, compared with ordinary cars, the 98% chance of winning the bid for new energy vehicles is already much higher.

Shanghai:

In 2012, Shanghai promulgated the Interim Measures for the Pilot Implementation of Encouraging Private People to Buy and Use New Energy Vehicles in Shanghai, in which plug-in hybrid passenger cars will receive a subsidy of 30,000 yuan each, and pure electric passenger cars will receive a subsidy of 40,000 yuan each, and special license plates can also be obtained free of charge (at present, the auction price of Shanghai automobile license plates is around 70,000 yuan-100,000 yuan). Of course, subsidized vehicles should also enter the Information Form of Pilot Vehicles for Private Purchase of New Energy Vehicles in Shanghai issued by the Shanghai Economic and Information Committee.

It is worth noting that the above policies expired at the end of 2012, and the new subsidy standards in Shanghai have not yet been introduced. However, the editor learned from the dealers in Shanghai that the purchase of new energy vehicles can still be implemented according to the old policy, and the new policy will be introduced in the near future, and the subsidy may be reduced.

Guangzhou:

In 2012, Guangzhou issued the Trial Measures for Purchasing Subsidies for Energy-saving and New-energy minibuses in Guangzhou, which showed that after vehicle registration, new-energy minibuses and hybrid vehicles with a fuel saving rate of more than 20% were given a subsidy of 10,000 yuan per vehicle. Although the amount of subsidy is small, and the subsidized models also need to enter the Catalogue of Recommended Models for Demonstration and Application of Energy-saving and New Energy Vehicles of the Ministry of Industry and Information Technology, the models include non-plug-in hybrid models, and in theory, more models will be subsidized.

In addition, according to the "Trial Measures for the Regulation and Management of the Total Number of Small and Medium-sized Passenger Cars in Guangzhou", all new energy vehicles that meet the "conditions" can also be shaken in the incremental indicators of 12,000 new energy vehicles in Guangzhou. Compared with ordinary cars, the chances of winning the lottery are higher.

It is understood that the "Trial Measures for Purchasing Subsidies for Energy-saving and New Energy minibuses in Guangzhou" will expire on March 31, 2014, and there is no continuous policy yet. Not long ago, Pan Jianguo, director of the Guangzhou Municipal Development and Reform Commission, revealed that in the future, Guangzhou citizens will be subsidized to buy new energy vehicles according to the ratio of 1: 1 between the central and local governments. In addition, citizens who buy new energy vehicles can also apply for a lottery directly. From this point of view, Guangzhou will soon adjust the existing subsidy and lottery policy for purchasing new energy vehicles to adapt to the national subsidy policy in the next few years.

Shenzhen:

In 2010, Shenzhen’s "Subsidy Policy for Private Purchase of New Energy Vehicles" was first introduced. At present, Shenzhen can enjoy the national and local 1:1 subsidy policy for purchasing electric vehicles and plug-in hybrid vehicles. It is also known that in the face of the new energy subsidy continuation policy issued by the state, Shenzhen is working on the relevant detailed rules for local new energy vehicle subsidies. The proposed plan may not be "decreasing year by year" like the central financial subsidy, but continue to adopt the original subsidy standards, namely, the maximum subsidy for pure electric vehicles is 60,000 yuan/vehicle, and the maximum subsidy for plug-in hybrid vehicles is 35,000 yuan/vehicle.

● Those "black boxes" mixed in the new energy vehicle policy.

After a general understanding of the national subsidy and local subsidy policies for new energy vehicles, most consumers will think that these policies are perfect. However, after editing and investigation, it is found that some key issues are very obscure, and they are like "black boxes". If we don’t open them one by one, we will inevitably have misunderstandings in the purchase of new energy vehicles.

It is not possible to buy new energy vehicles in any area.

It has been clearly pointed out in the notice on continuing to promote and apply new energy vehicles issued by the state that it will continue to promote and apply new energy vehicles relying on cities, especially megacities. If the conditions of demonstration cities or regions are met, an implementation plan for the promotion and application of new energy vehicles can be compiled and submitted to the four ministries and commissions, and the list of demonstration cities can be determined on the basis of merit.

In other words, only cities that enter the demonstration list can promote new energy vehicles, and local consumers can buy new energy vehicles locally and enjoy subsidies. At present, the four ministries and commissions have published two lists of cities or regions for the promotion and application of new energy vehicles, including first-tier cities in North, Shanghai, Guangzhou and Shenzhen, as well as urban agglomerations such as Hebei Province and Zhejiang Province. According to statistics, the two lists include 40 pilot cities or regions. If you want to know whether your place is a new energy demonstration city, you can click here to see [1] [2].

Not all new energy vehicles can enjoy state subsidies.

When understanding the national subsidy policy, we must carefully read the scope of subsidized vehicles, because not all new energy vehicles can get subsidies.

According to the Notice on Continuing the Promotion and Application of New Energy Vehicles, the new energy vehicles included in the scope of central financial subsidies should meet the requirements of pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Among them, the words "meet the requirements" mean that vehicles need to enter the Catalogue of Recommended Vehicles for Demonstration and Application of Energy-saving and New Energy Vehicles, and the vehicles that enter this catalogue are selected from the Announcement of Vehicle Manufacturers and Products of the Ministry of Industry and Information Technology, and only domestic vehicles such as independent and joint ventures will be included in this announcement.

After going around for so long, it’s actually a sentence—Imported new energy vehicles cannot enjoy state subsidies.

. Having said that, I believe many friends will question, isn’t the preferential policy given by the state to new energy vehicles just to promote energy conservation and emission reduction and promote air pollution control? So why is there a "nationality" when facing new energy vehicles?

In my opinion, the national new energy subsidy policy will shut out imported cars, so the scope of consumers will be reduced when buying cars; However, on the other hand, if subsidies are given to imported new energy vehicles, it is likely to increase their sales, which will certainly have an impact on self-owned brand vehicles and will not help China’s new energy vehicle industry to substantially improve. However, the subsidy policy is not to save the poor. Without core technology, it is impossible to speed up the industry by relying on policy subsidies blindly. Because the national policy has also given multinational car companies a new export-domestic.

Reading the Notice on Continuing to Promote and Apply New Energy Vehicles carefully, it is not difficult to find that the relevant policies issued by the state are first to accelerate the development of new energy vehicle industry. Although the subsidy policy refuses to import new energy vehicles, joint ventures can make imported new energy vehicles domestically or build joint-venture independent products to obtain subsidies. In this way, we can still leave some technology behind. At present, in fact, many joint ventures have set foot on the road of joint ventures and independent brands, and in order to comply with national policies, their first products have been designated as new energy vehicles, such as Dongfeng Nissan Qichen Chenfeng e30, FAW-Volkswagen Carrier Electric Vehicle, BMW Brilliance and so on.

Enjoy the "state" subsidy models, may not be able to get subsidies in the "local".

In theory, new energy vehicles that can receive state subsidies will naturally receive subsidies from local governments. But after investigation, it is found that this theory may not work everywhere.

For example, the new energy vehicles that enjoy local subsidies in Beijing do not include plug-in hybrid vehicles, and only pure electric vehicles and fuel cell vehicles that enter the Catalogue of Beijing Demonstration and Application of New Energy Passenger Cars, which is formulated by Beijing itself, can enjoy government subsidies.

When communicating with some dealers, the attitudes of dealers of different brands are also obviously different. A BYD salesman said, "Now you can’t get subsidies for buying e6 electric cars in Beijing, and it’s uncertain whether you will enter the subsidy catalogue in Beijing in the future.". In contrast, the dealers of Beijing Automobile are very confident, and the sales said, "Beiqi electric vehicles have entered the Beijing subsidy catalogue, and now they can enjoy a 1:1 subsidy when buying a car."

Not only in Beijing, but also in Shanghai, the sales staff of Roewe 4S store said that "E50 electric vehicles can enjoy subsidies". Another dealer said, "You can’t get subsidies for buying BYD e6 here". It is understood that only vehicles that enter the Shanghai new energy vehicle subsidy catalogue can enjoy local subsidies. At present, the Shanghai Economic and Information Committee has announced four batches, among which the local brand models Shanghai GM Sail SPRINGO electric vehicle and SAIC Roewe E50 were the first to be approved.

What causes the local subsidy policy to take more care of "local electric vehicles"? Some insiders said that this is the same as the state subsidy refusing to import cars, and it is "local protection". We won’t discuss this too much for the time being. After all, the first batch of subsidies in Beijing has not yet been issued, and the relevant rules for new energy vehicles in other regions have not yet landed. At present, the state has made it clear that the number of foreign brands in vehicles promoted and applied in demonstration cities or regions shall not be less than 30%. Do not set up or set up obstacles in disguise to restrict the purchase of foreign brand vehicles. Literally, the state’s attitude towards "local protection" is very firm, and we hope that this requirement will not become a dead letter when it is implemented and supervised.

New energy vehicles are not sold in all 4S stores.

In addition to policy-related matters, at present, some automobile manufacturers are not in place in the pre-sales service of new energy vehicles. Not long ago, the editor, as a potential consumer of new energy vehicles, tried to consult some information about new energy vehicles through the internet and telephone. From the result, the experience is not ideal.

On the official websites of some car companies, there is no detailed introduction to their electric vehicles. On some websites, even the place of sale is not publicized. The editor continuously called a brand’s 4S stores in three different regions to consult new energy vehicles, but they were all told not to sell them here, and a 4S store selling electric vehicles also introduced the local electric vehicle subsidy policy vaguely.

Here, I hope that manufacturers can quickly establish a set of perfect pre-sales and after-sales systems for new energy vehicles. At the same time, it is also suggested that potential users of new energy vehicles can consult the official 400 first to find out where the vehicles are sold, which can reduce useless work to some extent.

● Summary:

The subsidy policy itself is a catalyst for the development of new energy vehicles. The state and local governments go into battle together, so that consumers can get double benefits when buying new energy vehicles, which can effectively increase the sales of new energy vehicles. In addition, if we can make no distinction between "nationality" and "household registration", or at least get through the latter, so that new energy vehicles can be subsidized in more cities, perhaps new energy vehicles can develop faster in China.

Of course, it is far from enough to rely on policy support to promote new energy vehicles, and it is particularly important to rapidly develop the construction of related supporting facilities. At present, the state has made it clear that if applying for a demonstration city or region, it is necessary to formulate plans for the cumulative promotion of new energy vehicles and the construction of supporting facilities. Whether these military orders can be realized in future demonstration cities is worthy of attention. (Text/car home Qi Tianxiang)

　　Shortly after the bell rang on the first day of the promotion at 20:00 on May 13, 2025, the mobile phone that Ms. Fu of Dongguan City, Guangdong Province just placed in Tmall was delivered to her home by SF Brother. This is the first express delivery of Tmall 618 3C in 2025. This single delivery not only opened a new curtain for upgrading the logistics service industry under the dual-drive background of "national subsidy +618 promotion" in 2025, but also reflected the industry benchmark strength of SF as the head of the industry in terms of policy response speed, delivery stability and terminal execution ability.

　　Make up for the country and promote the rejuvenation of categories:

　　SF category expansion+intelligent collection to create a dual engine of state-funded logistics

　　In 2025, with the continuous promotion of the national subsidy policy, the national subsidy will expand its consumption in multiple categories at the 520 and upcoming 618 consumption promotion nodes. SF actively responded to the policy call, and comprehensively upgraded the full-link "rejuvenation delivery" solution for the "state subsidy" scenario, with multi-category expansion and AI testing technology capability guarantee.

　　First of all, in terms of service categories, SF has further expanded its support for "personalized rejuvenation" categories such as early education machines, electronic dictionaries and girlfriends machines on the basis of conventional high-frequency 3C categories such as mobile phones, smart wear, tablets and notebooks, and the service scenarios are closer to the needs of family users, parents and children and social gifts.

　　Secondly, in terms of terminal information collection capability, SF Express relies on mature terminal delivery system and intelligent terminal equipment to provide "one-stop collection of national compensation information" service to meet the requirements of product delivery startup/activation picture collection and serial code picture collection. Face-to-face on-site closed loop, and support the differentiated demands of different customers.

　　It is worth mentioning that in the face of massive subsidy delivery orders and the diversified implementation needs of customers such as e-commerce platforms and brand manufacturers in the subsidy scenario. For example, in the face of the difference of policies in different places and the different information collected by distributors of various platforms and sub-categories, SF Express can adjust effectively and quickly, support diversified verification methods, flexibly combine modules and go online quickly to meet the standards of subsidy rules in different categories and different places.

　　On the whole, SF has built its unique advantage in the state-funded delivery scenario: one-stop collection. The information collection process is embedded in the logistics node, and when the goods are delivered, the on-site collection of national compensation information is directly carried out to improve the overall service efficiency; Full link security. Ensure the safety of goods and accurate subsidies through multiple verification by means of serial code verification, AI detection and other technical means; Customized service. Support special customers’ demands for diversity collection of national compensation tasks.

　　Festivals are polite and rejuvenated quickly.

　　Shunfeng leads the national logistics track with professionalism.

　　This year, Tmall 618 countries made up for the first purchase, focusing on "spot, cheap and simple". Consumers can not only buy spot state-subsidized goods in advance, but also enjoy the state subsidy preferential treatment by superimposing the rights and interests such as promoting official reduction, large consumption coupons, interest-free installment and trade-in subsidies. Among them, the discounts for mobile phones, computers, flat-panel watches, digital products and other categories are as low as 50%. Among popular brands and single products, Apple dropped by 2,000 yuan, and iPhone16 Pro also entered the national subsidy for the first time, and the hand price was only 5,499 yuan. Chinese tonic goods can be delivered in time through SF Logistics, so that consumers can experience the happiness of promoting consumption in the first time.

　　The national subsidy policy has temperature, holiday gifts have attitude, and SF service has speed. The state subsidy policy is not only a key lever to boost the economy, but also a powerful path to improve people’s livelihood, optimize the structure and promote consumption. When the national subsidy policy overlaps with the "520" and "618" promotion nodes, SF Express, as a positive responder of the policy and a deep builder of scientific and technological logistics services, builds a solid delivery pillar for the temperature of the national subsidy policy with reliable professional guarantee, stable performance delivery and exclusive national subsidy service, providing consumers with a reliable path of trust and truly benefiting the people.

On May 19th, Huawei held a new product launch conference for nova14 series and HarmonyOS computers in Chengdu, and released two extraordinary masters of HarmonyOS computers, HUAWEI MateBook Pro and HUAWEI MateBook Fold.
