　　　　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.

　　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..

　　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.

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.

The financial business has a very high "gold content" among foreign automobile companies. For example, there are only two major business segments: "manufacturing+finance", and the profits from the financial segment also exceed 20% of the total profits of the public. The financial sector made a greater contribution to GM. Before the bankruptcy of GM, the profit from financial business accounted for more than 60%.

Gu Feng was given the "task" by Chen Hong, chairman of SAIC, to increase the profit of SAIC’s financial business from about 8% at present to 15%-20%. In order to achieve the goal smoothly, SAIC Finance Department was established, and Gu Feng was appointed as the general manager. At the same time, Wu Heng, deputy general manager of the Finance Department, and more than a dozen middle and senior cadres of SAIC were appointed.

Now, with Gu Feng’s departure, whether SAIC’s huge plan in financial business can continue to be implemented remains to be further verified.

Following the departure of Zhang Hailiang, former vice-president of SAIC, and joining LeTV in March this year, the senior management team of SAIC changed again.

A few days ago, 21st century business herald reporter learned that Gu Feng, CFO of SAIC (equivalent to vice president of SAIC), has submitted his resignation report, which is currently awaiting the approval of Shanghai SASAC.

Together with Zhang Hailiang, who left in March this year, this is the second vice president-level executive of SAIC in half a year.

Like Zhang Hailiang, Gu Feng was born after 70, and his career was in the prime of his life. People who are familiar with him are very appreciative of his professional ability and personality. In addition, like Zhang Hailiang in charge of SAIC’s service and trade sector, Gu Feng is also responsible for the transformation of SAIC. In the first half of this year, SAIC has established a financial division, with Gu Feng as the general manager.

After the establishment of the financial business department, Chen Hong, chairman of SAIC, hopes that the financial business profit will now account for about 8% of SAIC’s total profit and rise to 15%-20% in the future. This is also an important symbol of SAIC’s transformation from a traditional automobile manufacturing industry to a comprehensive company that provides comprehensive services to consumers, and will directly affect SAIC’s market value promotion plan, which Gu Feng has also made before. With Gu Feng’s "departure", whether Chen Hong’s transformation plan can be smoothly promoted is also facing a test.

Salary limit must be an excuse.

Some people think that Gu Feng’s resignation was due to "salary restriction". SAIC began to implement the salary limit system in the second half of last year, and the annual salary of municipal cadres has been greatly adjusted.

Generally, the level of vice-president is deputy bureau level. According to the standard of city management cadres, the annual salary is only 600,000, and Gu Feng is one of them. There are more than 1,000 people in SAIC with an annual salary of over one million, which also means that as the vice presidents of SAIC, Gu Feng, Zhang Hailiang and others have an annual salary less than that of an engineer. Prior to this, in 2015, the annual salary of the vice presidents of SAIC Group exceeded one million.

Then compare other companies in the automobile industry horizontally. Generally, private enterprises are native to vice-president professional managers with an annual salary of at least one million, and there are not a few imported talents with an annual salary of more than two million. In 2015, President and Executive Director Gui Shengyue had the highest annual salary, reaching 8.646 million; Executive Director Hong Shaolun, with an annual salary of 7.353 million yuan; Wei Jianjun, the chairman, ranked third with a salary of 5,692,400 yuan.

Even so, a person familiar with Gu Feng told reporters: "It must be an excuse to say that Gu Feng left because of salary restrictions."

Gu Feng, born in 1972, graduated from Shanghai University of Finance and Economics with a doctorate in management and a professor-level senior accountant.

As a trained financial man, if he valued his income, he didn’t need to stay in SAIC for a long time. As a traditional manufacturing industry, the annual salary of SAIC executives is only 2 million yuan, which is really insignificant compared with the financial industry.

According to the average wage of urban employees in 2015 released by the National Bureau of Statistics in May this year, the financial industry is still the industry with the highest income, and the annual salary of financial executives is relatively common.

Gu Feng, who could have entered the hottest financial industry naturally, dedicated his career of nearly 20 years after graduation to SAIC.

Gu Feng, who joined SAIC in 1997, participated in the establishment of Shanghai General Financial System. In 2001, after being transferred to SAIC, he led and participated in SAIC’s overall restructuring and listing in three places in 2004 (Shanghai, Hong Kong and new york, but failed to be listed in the end due to various reasons). In 2016, he led SAIC’s whole vehicle business to be injected into the listed company 600104 (the first case in Shanghai and Shenzhen), and led the acquisition of SAIC in 2007. At the same time, using the capital market platform to actively explore the financing channels of SAIC, during his tenure, he raised nearly 40 billion yuan through financial products such as separate transactions and convertible bonds, private placement and medium-term notes, and finally took the lead in setting up the first 20 billion standby syndicated loan in SAIC’s history. The scope of use of syndicated loans has opened up a new direction for standby syndicated loans.

As the chief financial officer in charge of the company’s financial power, Gu Feng also devoted a lot of energy to independent brands, including how to give more support to independent brands from financial resources, how to formulate more reasonable financial processes and systems for independent brands, and how to make independent brands develop more healthily.

At the same time, SAIC has been acquiring and merging its own brands in recent years, and the financial team led by Gu Feng has been actively exploring mergers and acquisitions with the Group, making a strict risk assessment from the financial point of view, and evaluating the long-term value of the acquired fields and whether they meet the company’s future strategic needs and value-added, so as to promote SAIC’s value investment in emerging technology fields.

During his career of nearly 20 years, Gu Feng has served as the deputy manager of the finance department of Shanghai Automotive Industry (Group) Corporation, the deputy manager of the finance department of Shanghai Automotive Group Co., Ltd., the executive director of the capital operation department, the financial controller and the executive director of the capital operation department. Along the way, he is currently CFO of SAIC, general manager of Shanghai Automotive Hong Kong Investment Co., Ltd., general manager of Shanghai Automotive Group Investment Management Co., Ltd. and general manager of SAIC Finance Division.

Elephant turns to PK new platform and goes into battle lightly.

Where to go after SAIC left? Gu Feng himself has not yet announced it. "I want to have a rest first." Gu Feng said.

People who are familiar with Gu Feng speculate that he should enter a new automobile enterprise or a transformation franchise company to engage in his financial "old line".

"With its personal ability and strength, it is possible to make a leap on a new platform and a new starting point." People familiar with Gu Feng think.

In fact, this time coincides with the transformation of SAIC. Under the leadership of Chen Hong, SAIC is actively seeking transformation. Chen Hong integrated SAIC’s business into four sectors: vehicle, parts, automobile service trade and finance.

However, after all, the elephant turns around. For a behemoth like SAIC, any small change means that it may cost a lot. This is also the reason why many large international companies prefer to be conservative rather than innovative.

For SAIC executives, in the traditional manufacturing industry, they will also encounter the ceiling of career development. For example, for Gu Feng, there is almost no room for CFO to move up, unless he leaves SAIC and enters government departments. For example, Ding Lei, the former vice president of SAIC, left the top official of SAIC to be the deputy head of Pudong New Area, but eventually jumped out of the "circle" and joined LeTV with Zhang Hailiang.

On the contrary, the outside world is wonderful. For example, Zhang Hailiang and Ding Lei, who have left SAIC, have successively joined LeTV and become their executives responsible for global business and China business; For Gu Feng, after jumping out of SAIC, it has a wider range of choices. Like Ding Lei, Zhang Hailiang, it can join a new automobile company and enter the financial industry. The financial industry is mostly international, and for Gu Feng, it has more opportunities to display its talents.

Chen Hong’s transformation business faces challenges.

However, Gu Feng’s departure can only be described as "pity" for SAIC.

SAIC is at the critical stage of improving market value management. After taking over from Hu Maoyuan as the chairman of SAIC in August 2014, Chen Hong was questioned by investors at several shareholders’ meetings of SAIC: SAIC’s financial situation is very healthy, and it was called the "most valuable investment" target of A shares by investors, but SAIC’s share price is not high.

Improving market value management has also been written into Chen Hong’s work agenda. In August last year, Chen Hong revealed that SAIC has added the company’s market value management function and investor relations maintenance work in the office of the board of directors.

At the same time, SAIC has implemented SAIC’s transformation strategy through a series of innovative business expansion. According to Chen Hong’s plan, SAIC will accelerate from a traditional enterprise mainly relying on manufacturing to a comprehensive supplier providing consumers with all-round products and services, and strive to become a world-famous automobile company with global layout, transnational operation, international competitiveness and brand influence.

The "task" given by Chen Hong to Gu Feng is to increase the profit of SAIC’s financial business from the current 8% to 15%-20%. In order to achieve the goal smoothly, SAIC Finance Department was established, and Gu Feng was appointed as the general manager. At the same time, Wu Heng, deputy general manager of the Finance Department, and more than a dozen middle and senior cadres of SAIC were appointed.

The financial business has a very high "gold content" among foreign automobile companies. For example, Volkswagen’s business sector has only two large pieces of "manufacturing+finance", and the profit from the financial sector also exceeds 20% of the total profit of Volkswagen. The financial sector made a greater contribution to GM. Before the bankruptcy of GM, the profit from financial business accounted for more than 60%.

After the establishment of the Finance Division, Gu Feng once revealed ambitiously that the future SAIC Finance Division mainly involves four major functions. First, SAIC will integrate and re-plan the businesses of SAIC Finance Company, SAIC General Finance Company, SAIC Equity Investment and Insurance Company under the Finance Division, with the purpose of linking the financial business with SAIC’s industry, so that the financial business can serve the industry, such as launching the business of car owners’ wealth management and car owners’ balance treasure. Even, the financial department may expand SAIC’s financial business by acquiring banks or insurance companies.

Second, after the establishment of the Financial Division, the financial business of SAIC will be centrally managed. Formulate KPI performance appraisal indicators suitable for financial business. Thirdly, SAIC Finance Division will also have the function of investment bank, and make mergers and acquisitions or acquire technologies through the leverage effect of financial business, so as to enlarge and strengthen the business sector. The fourth is to further enhance SAIC’s asset allocation capability.

Now, with Gu Feng’s departure, whether SAIC’s huge plan in financial business can continue to be implemented remains to be further verified.

　　(CCTV reporter Zhang Chunling Cao Yuzheng)

　　Fuzhou News Network July 19 (Fuzhou Daily reporter Mo Siyu Jun Wu) The renovation project of Red Star in Taijiang District and its surrounding old houses ushered in new progress. The reporter learned from Taijiang District on the 19th that at present, more than 3,000 residential houses involved in the project have been completely relocated and demolished, with a total construction area of more than 960,000 square meters, and the collection has entered the final stage.

　　The renovation project of Hongxing and its surrounding old housing areas is the largest old housing area renovation project within the Second Ring Road of our city at present. The total number of households involved in relocation is 7858, and the total area of houses to be expropriated is about 1.003 million square meters. The expropriation was officially started on September 18, 2017.

　　"Finally wait until this day!" Guo Dajie, who originally lived in Hongxing New Village, expressed the voices of many relocated households. Although the plot is located in the central city, it is a mixture of private houses, old prefabricated new villages, industrial warehouses, unit dormitories, etc. The housing density is high and the population is dense, and the public supporting facilities are obviously lagging behind. The voice of the masses for old reform is very strong.

　　Chen Jinhuo’s family of 11 people in Paiwei Community is crowded into an old house of 109 square meters, and Liu Ruihua’s family in Yangzhongli is always on tenterhooks every typhoon day … In the renovation project of old houses in Hongxing and surrounding areas, there are not a few families like them who live in high density and look forward to improving housing conditions.

　　7858 households, such a heavy collection work, how to implement it scientifically and efficiently? The "five in one" harmonious expropriation of "scientific expropriation, joint expropriation, efficient expropriation, sunny expropriation and tender expropriation" is the answer given by Taijiang District.

　　Zhu Teng, deputy head of Taijiang District, told the reporter that the plot was divided into four areas, A, B, C and D, each of which was covered by four teams in the district. Nearly 500 cadres and workers from 10 streets in the whole district have formed more than 20 working groups, all of which have been pressed to the front line, and have gone deep into households and units under their jurisdiction to carry out publicity and mobilization, forming a strong joint force to promote the work.

　　Whether it is the 89-year-old elderly who are hospitalized in Minhou or the property owner who is serving a sentence in Wuyishan, as long as the people need it, the collection staff always overcomes all difficulties to provide them with on-site services. "We hope that through on-site service, those people who have difficulties can understand the policy, dispel their doubts and truly trust us, thus promoting the development of land requisition and relocation." Zhu Teng said.

　　It is precisely under the promotion of the "five in one" collection that up to now, 7,852 households have been relocated in the renovation project of Hongxing and its surrounding old housing areas, with a total of 28,767 people relocated. The houses of the households involved have been completely relocated and demolished, and only the production of the remaining six provincial and municipal units is still being coordinated.

　　According to reports, the renovation project of Hongxing and its surrounding old housing areas involves 321.15 mu of administrative office land, educational and scientific research land, social welfare land, water system land and urban road land, which can be used to build 443.85 mu of resettlement housing land. According to the latest planning of the Municipal Planning Bureau, more than 700,000 square meters of resettlement houses can be built.

　　"The renovation and post-development of the old housing area can not only improve the living conditions of the people in the region, but also further develop the high-end commercial industry and create a new commercial center and emerging urban complex in Taijiang." Zhu Teng said.

Country Garden was petitioned for liquidation and bankruptcy was imminent.

Country Garden objected to the liquidation petition, and the company was finally liquidated.

On February 28, 2024, Country Garden announced that the company was informed that EverLimited filed a liquidation petition against the company in the High Court of the Hong Kong Special Administrative Region on February 27, concerning the unpaid term loan with a principal of about HK$ 1.6 billion and accrued interest between the petitioner and the company.

On October 10, 2023, Jiantao Group announced that Country Garden failed to repay the money according to the financing agreement, and the lender issued a statutory demand for repayment to Country Garden, demanding repayment of some due payables.

　　Diplomacy is no small matter. Some seemingly casual details often reveal meaningful signals.

　　Just now, in the Oval Office, US President Trump met with Liu He, Vice Premier of the People’s Republic of China, the special envoy of the Supreme Leader. The meeting lasted 40 minutes. According to the subsequent release of Xinhua News Agency, Trump also emphasized to Liu He:I highly cherish the good working relationship and personal friendship with the Chairman of the Supreme Leader.

　　Trump, the chief correspondent of Twitter in the White House, also quickly posted relevant information on Twitter, saying that he had talked with Liu He about trade issues. In the photo, Trump with a red tie stood on the right and Liu He with a blue tie stood on the left. They shook hands and smiled.

　　Sino-US trade negotiations are still going on, but during the talks, Trump suddenly met Liu He at the White House, and the information conveyed should be quite rich, at least these three clear signals:

　　1. There have been subtle changes in the attitude of the United States.

　　The last time Liu He visited Washington, not long ago, US Treasury Secretary Mnuchin led a delegation to Beijing for consultations, but the top leaders of the two countries did not come forward to meet. But this time, Trump not only met with Liu He, but also smiled brilliantly.In addition to Mnuchin and other US ministers, accompanied by US Vice President Burns. The President and Vice President of the United States met with Liu He, a vice-national.It can also be seen that the US attaches great importance to the China delegation.

　　In addition, in the Xinhua News Agency report, the first thing Trump said to Liu He was,"It is very important for the United States and China to maintain good cooperative relations in the economic and trade field." Please note that this is "very important".Since it is very important, the United States should also be soberly aware that once it derails, it will shake the earth.

　　Second, China and the United States have differences, but both want to solve them properly.

　　According to Xinhua News Agency, Trump said to Liu He:"I hope that the economic teams of the two countries will work together to actively solve the problems existing in the economic and trade relations between the two sides."Liu Heze said:"China is willing to work with the United States to properly handle and solve economic and trade issues of mutual concern on the basis of equality and mutual benefit, and ensure that economic and trade cooperation will continue to be the ballast stone and propeller of Sino-US relations."

　　There are indeed big differences between the two sides. What should we do? Please note that the Chinese word is "properly handled" and Trump’s word is "actively resolved". There are subtle differences in words, but their attitudes are basically the same. In other words, both sides believe that these differences should not be allowed to affect the relations between the two countries, which creates better conditions for the final success of the negotiations. Of course, China also has principles: on the basis of equality and mutual benefit.

　　Third, there is huge space for future cooperation between China and the United States.

　　During the meeting, Trump also said this to Liu He:The United States and China should focus on strengthening trade and investment cooperation in the fields of energy and manufacturing, expanding agricultural products trade and market access, and strengthening cooperation in intellectual property protection to bring more practical benefits to the two peoples.

　　This should be the key cooperation area listed by the United States.These are all businesses, and China really may not suffer.It must be noted that in these areas, the United States has great advantages, and China’s appropriate increase in some imports is conducive to meeting people’s needs for a better life and is more conducive to the formation of a domestic competitive market. For example, energy is the blood of the economy, and China needs to import a lot of energy to develop; China needs blue sky, and natural gas is in short supply. In this regard, the United States can make more contributions. Of course, China’s energy exploitation technology should also catch up quickly.

　　In the previous article, bullpiano said,The trade war between China and the United States seems to be on the verge of exploding, but from the perspective of the ultimate win-win situation of harmony and wealth, it is just a fierce bargaining before larger-scale cooperation.

　　For the delegation of China, this is really a heavy responsibility. We must defend China’s legitimate rights and core interests, and we must defend the multilateral free trade system and global free trade.

　　Because in the process of consultation, there is no lack of wild speculations. Some western media also broadcast the so-called news that China made substantial concessions and accepted the US deficit reduction of $200 billion.

　　However, people familiar with the matter made it clear that this is false and purely misunderstood.

　　According to the interpretation of relevant people:

　　1. It is absolutely impossible for the Chinese team to negotiate under the conditions set by the US. This point has long been made public in the last round of Beijing consultations.

　　2. Some of China’s concerns, such as the ZTE incident, have been hinted by the relevant US parties in Twitter a few days ago; In addition, both sides have made progress in expanding the export of chips and high-tech products to China in the United States and relaxing energy exports to China. The final result of this transaction is worth looking forward to. Some people worry that China will make unilateral concessions, which is unnecessary.

　　3. The final result of the negotiations will come out after a while, and the so-called rumors of China’s concessions will be broken by then!

　　However, this is still a bitter battle.

　　According to informed sources,Just a few hours before Trump met with Liu He, the two sides still refused to give in to each other on the focus issue, and the negotiations were once deadlocked.Trump’s sudden meeting and the smiling handshake between the two sides undoubtedly put an end to the hard negotiation of this day.

　　Negotiations will continue and the game is still going on. Strive for the best results and prepare for the worst.Tomorrow is a crucial day!(Author Niu Qinqin)
