　　On April 20th, in state administration of traditional chinese medicine, Wei Chunyu, deputy director of the Department of International Cooperation of state administration of traditional chinese medicine, said that state administration of traditional chinese medicine has been stepping up its efforts in recent years, strengthening the top-level design and overall planning of cultural promotion, and promoting the "going out" of Chinese medicine culture.

　　As the original medical science of the Chinese nation, TCM is rooted in the philosophical wisdom of the Chinese nation and the excellent traditional culture soil, and has integrated the essence of natural science and humanities in China. At present, Chinese medicine has spread to 196 countries and regions. In December 2021, state administration of traditional chinese medicine and the Office of the Leading Group for Promoting the Construction of the Belt and Road jointly issued the Development Plan for Promoting the High-quality Integration of Chinese Medicine and Building the Belt and Road (2021-2025). One of the key tasks is to deepen cultural exchanges and cooperation and strive to enhance the influence of Chinese medicine. In February, 2023, the State Council issued the Implementation Plan of Major Projects for the Revitalization and Development of Traditional Chinese Medicine, which clearly formulated the plan to enhance the international influence of traditional Chinese medicine.

　　Wei Chunyu said that, with the development plan of "Promoting the high-quality integration of Chinese medicine and building the" Belt and Road "(2021-2025) as the starting point, relying on carriers such as overseas Chinese medicine centers, overseas China cultural centers and overseas high-level medical institutions, various forms of Chinese medicine cultural publicity activities will be held to promote high-quality Chinese medicine resources and services to the whole world, strengthen international communication and create quality projects. Strengthen cooperation with mainstream media at home and abroad, support the shooting of Chinese medicine film and television products, use short videos, cartoons, books and other ways to strengthen the popularization of Chinese medicine knowledge for different groups in the international community, and create Chinese medicine publicity products with spread and reputation. In-depth development of Chinese medicine overseas trips, "One Belt, One Road" acupuncture and other activities, through health consultation, exhibitions, experience tasting and other bright brands, continue to enhance overseas people’s understanding and recognition of excellent Chinese culture, including Chinese medicine.

A few days ago, Mr. Ma of Shijiazhuang Private Home Economics Service Co., Ltd. came to the Tax Service Hall of the Taxation Bureau of Chang ‘an District, Shijiazhuang City to apply for invoicing. Under the recommendation of tax officials, Mr. Ma used his mobile phone to log on to the mobile tax terminal of Hebei Online Taxation Bureau and entered the electronic invoice system. In one minute, an electronic invoice with an amount of 2,500 yuan was sent to the mailbox of the payee. "Very convenient! Usually, I don’t use many tickets, but it takes one hour to invoice from the company to the tax bureau, and I can invoice at any time no matter where I am! " Mr. Ma said happily.

On October 1st, Hebei Provincial Taxation Bureau began to implement the online tax-free electronic invoicing system for small and micro enterprises (hereinafter referred to as the "electronic invoicing system"). Taxpayers can APPly to the tax authorities for issuing VAT electronic ordinary invoices through the mobile phone app of Hebei Online Taxation Bureau.

The staff of the Goods and Services Tax Department of the Provincial Taxation Bureau introduced that the monthly sales are less than 30,000 yuan; VAT taxes have been approved but invoice types have not been approved; Taxpayers who meet the three conditions of unit taxpayer or individual industrial and commercial households with fixed personal income tax can use the electronic invoicing system to invoice customers 24 hours a day without leaving home.

It is understood that users who issue invoices need to pass real-name authentication to register the mobile APP account of "Hebei Online Taxation Bureau Mobile Tax Terminal" to ensure their identity is credible. All invoice data will be transmitted to the anti-counterfeiting tax control system in real time after being generated to ensure real-time correctness and effectiveness. The payee can also receive the electronic invoice immediately and check it on the mobile phone at any time. When taxpayers use the electronic invoicing system for the first time, they must first bind the billing QR code, and the billing code is one for each household. By scanning the billing code with Alipay, the payee can directly push the billing header information to the billing party, which not only saves the trouble of manual input by the billing party, but also is less prone to errors. After invoicing, the payee can view the invoice at any time in the "Invoice Management" interface of Alipay.

On October 25th, Ms. Su of Haixing County successfully issued her first electronic invoice through the mobile phone APP of Hebei Online Taxation Bureau. She used "three unexpected things" to express her inner joy: I didn’t expect it to be so simple that a mobile phone could do it! I didn’t expect it to be so intimate that I could do it without leaving home! I didn’t expect it to be so easy to use, and I can log in 24 hours!

According to statistics, by the end of October, 780 taxpayers in our province had used the electronic invoice issuing system and issued 1,203 electronic ordinary VAT invoices, amounting to more than 360,000 yuan. "The electronic invoicing system has not been put into use for a long time. We need to further strengthen the training and publicity for grassroots tax personnel and taxpayers, so that taxpayers can understand the system as soon as possible and fully enjoy the convenient invoicing service." Dong Xijuan, director of the Goods and Services Tax Division of the Provincial Taxation Bureau, said.

　WeChat official account News of CBN WeChat, the critical moment of COVID-19 epidemic prevention and control, a paper published in the New England Journal of Medicine, pushed the China Center for Disease Control and Prevention (hereinafter referred to as "China CDC") to the forefront.

The reason is that, according to this paper, research shows that interpersonal communication has occurred between close contacts since mid-December 2019. In addition, from January 1 to January 11, a total of 7 medical staff were infected. But at this time, the public knew nothing about it.

Should scientists publish papers first or prevent them first? The focus of controversy comes from this. On the morning of January 31st, CBN reporter interviewed Gao Fu, a member of the National Health Commission high-level expert group and director of China CDC. He is the co-author of the above paper.

"This is a retrospective analysis! In mid-December, I still don’t know what the disease is, and the pathogen is unclear. It is the inference of investigating more than 400 cases of epidemiology! Onset’s days are all speculation, which everyone didn’t understand! Mix epidemiological investigation with clinical diagnosis. " Gao Fu told CBN.

Gao Fu also said that retrospective investigation is one of the responsibilities of CDC, to find the culprit, retrospective investigation, and guide future prevention and control. "Our prevention and control has never stopped, and everyone has not slept for a month."

This is a retrospective analysis.

This paper, published on January 29th, US time, was led by China CDC, including professionals from Hubei CDC and Hong Kong University. Correspondents of the study include Feng Zijian, deputy director of China CDC, and Yang Bo, director of Hubei CDC. Co-authors also include Gao Fu.

In this paper, the investigation team analyzed the reported 425 laboratory-confirmed cases as of January 22, 2020. Analysis shows that among the first 425 confirmed patients, the median age is 59 years old and the male is 56%. Most cases (55%) occurred before January 1, 2020 were related to the seafood wholesale market in South China, and the subsequent cases were 8.6%. The average incubation period was 5.2 days, and the 95th percentile of the distribution was 12.5 days. In the early stage, the scale of epidemic cases doubled every 7.4 days, the average continuous interval of infection was 7.5 days, and the number of basic infections (R0) was estimated to be 2.2.

According to this information, the paper said that there is evidence that interpersonal communication has occurred between close contacts since mid-December 2019.

This paper reveals more information about the epidemic situation in COVID-19, which has aroused widespread doubts.

On January 31st, China CDC published an article entitled "Notes of China Center for Disease Control and Prevention on Publishing Articles in the New England Journal of Medicine". The article stated that the paper was based on a retrospective analysis of 425 confirmed cases (including 15 medical staff) reported as of January 23rd, 2020, and all cases were published to the public before the paper was written. The 15 cases of medical staff infection mentioned in the paper were announced to the public by Academician Zhong Nanshan, the leader of the high-level expert group in National Health Commission, on the evening of January 20th and the Wuhan Health and Health Commission in the early morning of January 21st.

The viewpoint that "interpersonal communication occurred among close contacts in December 2019" put forward in this paper is a retrospective inference based on the epidemiological investigation data of 425 cases.

The article also said that publishing the survey results in academic journals in time will help professional colleagues at home and abroad to understand the characteristics of the disease in time, jointly evaluate and judge the epidemic situation, and improve the prevention and control strategies.

However, this article did not respond, when did China CDC come to the judgment that "interpersonal communication occurred among close contacts in December 2019".

For infectious epidemiology, retrospective study is indeed extremely important. Without retrospective study, it is impossible to understand the incidence of infectious diseases more clearly and then formulate prevention and control strategies for infectious diseases. Therefore, after the outbreak of an infectious disease and case diagnosis, epidemiological investigators will appear first.

An expert in epidemic virology also told reporters that retrospective research is the basic work of infectious diseases and must be carried out according to existing cases. Without cases, no one can observe what the development path of this virus is.

"In fact, the data of 425 cases is not enough to show the characteristics of the new virus. It can only explain the situation in the past and (425 cases) at that time. How to develop in the future needs to continue to be observed." The above-mentioned experts in epidemic virology said.

For example, China CDC stated that these cases were previously confirmed cases, and the research team used these public data to start a retrospective analysis.

How to carry out retrospective analysis?

According to this paper, the earliest cases in COVID-19 were identified through the surveillance mechanism of pneumonia with unknown etiology.

In order to identify pneumonia cases and strive to improve the sensitivity of early detection, the research team developed a tailor-made monitoring program to identify potential cases on January 3, 2020.

The initial working case definition for suspicious COVID-19 is based on the case definition of SARS and Middle East Respiratory Syndrome (MERS). After obtaining new information about confirmed cases, the epidemiological criteria for defining suspicious cases were updated on January 18, 2020.

Once suspicious cases are found, a joint team composed of China CDC, provincial CDC, local CDC and county CDC will be notified to carry out detailed on-site investigation and collect respiratory tract samples, which will be tested in the Center for Viral Disease Prevention and Control of China CDC.

A joint team composed of staff from China CDC and local CDC also conducted detailed field investigations on all suspected and confirmed cases. They collected epidemiological data through interviews with infected people, relatives, close contacts and medical staff, so as to determine the contact history of patients two weeks before onset, including the date, frequency, frequency and mode of contact with wild animals, especially the wild animals available in the South China Seafood Market in Wuhan. In addition, the researchers also collected information about exposure to any relevant environment and contact with others with similar symptoms.

All the epidemiological information collected in the survey, including contact history, timetable and the identity of close contacts, were cross-checked.

Through this path, the research team obtained the epidemiological information of 425 cases.

The basic infection number is about 2.2.

The importance of retrospective analysis of infectious diseases lies in seeing clearly the laws of infectious diseases, and only by seeing clearly the enemy can we make better prevention and control.

In addition to the above-mentioned questioned contents, what other noteworthy information does this paper reveal?

In this paper, the researchers estimate the growth rate of the epidemic by analyzing the data of cases between December 10, 2019 and January 4, 2020.

According to the paper, limited to the data before January 4th, it is estimated that the basic number of infections in COVID-19 is about 2.2, which means that each patient spreads the infection to 2.2 other people on average. As far as COVID-19 is concerned, the paper said that the control challenges include the obvious existence of many mild infections and the limited resources to isolate cases and close contacts.

However, due to the increased awareness of the epidemic situation and the increased availability and utilization rate of inspections in recent weeks, the confirmed infection rate will increase.

A chart used in this article shows that after January 11th, the number of cases decreased. However, the paper also said that it is probably due to the uncertainty of recent cases and the delay in identification and reporting, rather than the real turning point of incidence.

Considering that the availability and usage of test kits will increase with the passage of time, the paper said that extra care should be taken in explaining the growth rate of cases in January.

In short, the research results also show that in the early stage, the case size doubled every 7.4 days. The average continuous interval is 7.5 days.

The paper also reminds that the urgent next step includes determining the most effective control measures to reduce the spread within the community. With a better understanding of epidemiological characteristics and the dynamic mechanism of cases, it is also necessary to improve the definition of work cases. At the same time, it is also necessary to continue to monitor cases to find any changes in epidemiology, such as infections among young people or medical workers.

Original title: Gao Fu responded to the paper’s query: everyone didn’t understand, confusing the paper with clinical diagnosis.

Coronavirus particle structure

　　Life is not easy, but health is the most expensive. A recent hot topic — — Novel Coronavirus, disturbing the biosphere. Today, I’ll pick up bats, civets and camels … … And novel coronavirus’s "Love and Kill".

　　Two "Black History" of Coronavirus

　　Coronavirus is a kind of pathogen that mainly causes respiratory and intestinal diseases. Laboratory experts have studied the morphology of viruses, and electron microscope observation shows that these viruses have spinous processes like corona on their envelopes, which looks like a crown, so it is proposed to name these viruses coronavirus.

　　Coronavirus was first isolated from chickens in 1937. There are two genera of human coronavirus (HCoV): α Coronavirus and β Coronavirus. Middle East Respiratory Syndrome Coronavirus (MERS-CoV) and Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) belong to β Coronavirus.

　　In 1965, Tyrrell et al. isolated a virus named B814 from nasal lavage fluid of common cold patients by human embryo trachea culture. Hamer et al. isolated a similar virus from human embryonic kidney cells, and the representative strain was named 229E virus. In 1967, Mclntosh et al. isolated a batch of viruses from cold patients by embryonic trachea culture, and its representative strain was OC43 strain.

　　We are no strangers to SARS and MERS. SARS spreads quickly, its condition is dangerous and its mortality rate is high. Since the outbreak in 2002, in a short period of two years, it has infected 30 countries in five continents, with more than 8,000 people infected and 774 people killed, with a fatality rate close to 10%.

　　In 2012, the first human case of MERS-CoV infection occurred in Saudi Arabia. The virus is a novel coronavirus with high mortality, and it can also cause severe acute respiratory infection. The source of the virus is not completely clear at present. However, according to the genome analysis of different viruses, it is believed that MERS-CoV may come from bats and spread to camels, and camels may be the main storage hosts and animal sources of human infection. However, MERS-CoV has been popular in camels for decades, and it was not until 2012 that it first infected humans. The reason is still unclear.

　　Coronavirus and its natural reservoir

Chinese chrysanthemum-headed bat

　　Coronavirus exists widely in nature, and its natural hosts include human, cattle, pigs, birds, dogs, cats, rats and bats. As the second largest mammal in the world after rodents, bats are distributed in all parts of the world except the poles, and their habitats are diverse. As a member of the biosphere, bats play an important role in maintaining ecological balance. At the same time, it is also an important virus host, carrying more than 130 kinds of viruses, including Ebola virus, Nipah virus and other virulent pathogens.

　　When it comes to SARS, people will think of civets. In fact, civet cats are just "intermediaries" rather than the source of the virus. According to the data, in 2003, a research group of Hong Kong University detected SARS-CoV in civet cats and raccoons in Shenzhen animal market, Guangdong province, and the civet coronavirus was nearly 100% homologous to the coronavirus that caused SARS in humans. In the subsequent investigation, it was found that the positive rate of civet cats in the live poultry market was very high, but the civet cats in the farm were almost not positive for SARS-CoV, which indicated that the civet cats were infected with SARS-CoV only on the way to the market or in the market, but the farm was not infected. Animal experiments have proved that SARS-CoV is pathogenic to civet cats, which also supports that civet cats are not the natural hosts of SARS-CoV. Therefore, civet cats are only susceptible animals to SARS virus.

　　For a new animal-derived virus, we must find its source, so what is its source? Shi Zhengli, a researcher from Wuhan Institute of Virology, Chinese Academy of Sciences, led the team to confirm that bats are the natural hosts of SARS-like coronavirus, and through genetic information analysis and functional testing of the virus, it was further confirmed that bats in China are the natural hosts of SARS-like virus, which provided important evidence for the animal traceability of SARS-like coronavirus. Therefore, researchers believe that bats may be the natural hosts of SARS coronavirus, and civet cats are only intermediate hosts, but the current research has not revealed the relationship between civet cats and bat infection.

　　Disinfection may not be "everyone is good at it"

　　Boil a pot, rinse with water, spray enough disinfectant and wear N95 protective mask … … Is there a scientific basis for the disinfection and anti-virus methods commonly used by ordinary people? Coronavirus is sensitive to heat. Experiments show that SARS-CoV can be inactivated by heating at 56℃ for 90 minutes or 75℃ for 30 minutes.

　　In addition, the virus is sensitive to ultraviolet rays and commonly used chemical disinfectants, such as 75% alcohol, iodophor, compound quaternary ammonium salt, chlorine-containing disinfectant, phenol disinfectant, aldehyde disinfectant, peroxide disinfectant, etc., which can inactivate the virus in a short time at the specified concentration. The virus is not resistant to acid and alkali, and is also sensitive to organic solvents such as ether and chloroform.

　　Coronavirus usually causes people’s common cold, and can cause lower respiratory symptoms in adults and infants. The main clinical manifestations are fever, cough and runny nose. In severe cases, it shows acute respiratory symptoms such as laryngitis, bronchitis, bronchiolitis and pneumonia, and there are also reports that lead to gastrointestinal and nervous system symptoms. In addition, it can also cause severe acute respiratory infection in special populations such as the elderly, children and people with immunodeficiency.

　　Previous research data show that patients infected with coronavirus are the main source of infection. The management of infected patients should be early detection, early reporting, early isolation and early treatment. At present, there is no specific vaccine or drug prevention method for coronavirus, and there is no approved antiviral drug for coronavirus. Patients are still mainly treated with symptomatic support.

At present, in the mainstream automobile market, in addition to the traditional fuel vehicles, there are also MHEV(48V light hybrid), HEV (oil-electric hybrid), PHEV (plug-in hybrid), REEV (extended range), BEV (pure electric) and FCV (fuel cell). In this field, consumers especially like to use oil-electric hybrid and plug-in hybrid as the first choice for car purchase, so what is the difference between oil-electric hybrid and plug-in hybrid, and which power system is more suitable for the current car environment?

　　The power system of hybrid electric vehicle is mainly composed of control system, drive system, auxiliary power system and battery pack. This hybrid system does not need to charge the battery. We only need to rely on the waste energy recovery of cars to store the electric energy. As we all know, under the condition of low-speed traffic jam and start-stop in the city, due to the influence of vehicle weight and load, it is often the most fuel-consuming stage of the engine. The advantage of the motor is that the torque at low speed is stronger and the dynamic response is more sensitive. Therefore, the combination of hybrid technology of oil and electricity can greatly reduce fuel consumption while ensuring power performance compared with traditional fuel vehicles.

　　Taking Toyota THS-II hybrid power system as an example, the power of engine, generator and driving motor is mechanically coupled by planetary gear mechanism. When starting and driving at low speed, only the motor is used to drive, achieving zero fuel consumption; During normal driving, the engine is used as the main power to drive the wheels, and at the same time, it drives the generator to charge and convert energy into electric energy; When fully accelerating, the engine and motor are driven at the same time, and the dynamic response is stronger; When slowing down or braking, the engine stops running, and the still rotating wheels drive the generator to recover energy, thus charging the battery.

　　Another Honda, which is a hybrid electric vehicle, adopts the dual-motor hybrid system i-MMD, which is suitable for being mounted on a medium-sized vehicle (such as the Accord). Different from Toyota’s THS system, Honda’s i-MMD system has a simpler structure, which is combined by the clutch between the engine and the motor.

　　Honda’s i-MMD hybrid system also uses dual motors, and compared with Camry, the motors on the Accord are more powerful. And the whole hybrid system is more inclined to be driven by motor. Under high-speed working conditions, the engine directly drives the car. In hybrid mode, the engine intervenes to charge the motor, and then the motor drives the car. Therefore, the hot hybrid electric vehicles in the market can be roughly divided into THS system of Toyota and i-MMD system of Honda Accord.

　　The hybrid Accord is because the engine only directly drives the wheels when cruising at high speed, which is equivalent to working only in the highest gear. The driving problems at low speed are all done by high-power motors, which simplifies the driving structure. The hybrid Camry uses planetary gear mechanism to realize the distribution of engine/motor power output. Although they have different working principles, they can have good fuel economy.

　　I have also tested the eighth generation Camry hybrid and the tenth generation Accord hybrid. When driving in the city, the Accord hybrid is stronger than the Camry hybrid in terms of dynamic response and vibration when the engine is involved.

　　In a macro sense, plug-in hybrid is also an oil-electric hybrid system, but according to the dependence of vehicles on electric energy, hybrid can be divided into weak hybrid (also known as MILD HYBRID, soft hybrid, micro hybrid, etc.), moderate hybrid, heavy hybrid FULL HYBRID (also known as full hybrid, strong hybrid, etc.) and plug-in hybrid. The Toyota Camry hybrid and Accord hybrid just cited belong to the category of strong mixing.

　　Compared with the hybrid version, the plug-in hybrid vehicle has a larger battery capacity (generally, it can travel more than 50Km on pure electricity), and provides a better fuel-saving ratio. It belongs to the hybrid vehicle with external power supply, and the main power output lies in the motor. Only after the electric output of the motor is exhausted can the traditional engine be used to travel, and the battery can be charged in time.

　　Take BYD Qin Pro DM version as an example. The DM dual-mode plug-in hybrid version will be equipped with a plug-in hybrid system with a 1.5T+ motor, with a maximum power of 113kW(154PS) and a permanent magnet synchronous motor with a maximum power of 110KW and a torque of 250 Nm. The pure battery life of MIIT is 80km. The transmission is matched with a 6-speed dual-clutch gearbox. The official 0-100Km/h acceleration time is 5.9s.

　　Advantages: Compared with the fuel version, it has higher fuel economy and driving texture.

　　The main power source of the hybrid electric vehicle is still the engine, but with the assistance of the motor, it can replace the most oil-consuming working condition of the engine. That is to say, when the city is driving at low speed and in congested conditions, the engine rarely intervenes. In most cases, the vehicle is driven by the motor, which avoids the waste of oil consumption when the engine is driving at low speed and the load is high, thus improving fuel economy.

　　Moreover, compared with the traditional fuel version with the same displacement, with the assistance of the motor, its dynamic performance is more excellent, and the dynamic response is more direct because it depends on the motor at low speed. In addition, at low speed or idle speed, the engine is stopped. Compared with the fuel version, the car is quieter and the driving quality is better.

　　Take the tenth generation Accord Sharp Hybrid as an example, it is equipped with the third generation i-MMD hybrid power system and a brand-new IPU (Intelligent Power Unit). The power system consists of a 2.0L naturally aspirated engine, dual motors, an e-CVT gearbox, a power control unit and a lithium battery. Among them, the 2.0L engine has a maximum power of 107 kW and a peak torque of 175 Nm. The maximum power of the motor is 135 kW, the peak torque is 315 Nm, the comprehensive output power is 158 kW, the acceleration of 100 km is only about 8 seconds, and the official comprehensive fuel consumption is 4.0L/100km.

　　At low speed and idle speed, vehicles and air conditioners and other electronic equipment are driven by motors, and they start quickly. However, in the case of rapid acceleration, the engine and the motor work together, and the engine intervenes smoothly with little vibration. Compared with the fuel version, it has a better and quieter driving texture, and at the same time, the fuel economy advantage is more obvious.

　　We also take the sales of Camry and Accord as examples. After the 10th Accord went on the market, by the end of the 18th century, the cumulative number of car owners had exceeded 120,000. In the fourth quarter, the average monthly sales of nearly 20,000 vehicles won the overall B-class car market sales champion, while the average monthly sales of Camry, the largest competing product in the same class, was 13,000 vehicles in the fourth quarter.

　　In addition, in January 2019, the sales volume of the 10th generation Accord terminal was 23,649 vehicles, up 24.9% year-on-year, of which 2,524 vehicles were sharp and hybrid, up 31.3% year-on-year, while Camry sold 19,720 vehicles. It can be seen that the Accord with lower pricing is more favored by consumers, and at the same time, more and more consumers are more willing to buy a more balanced hybrid model of oil and electricity.

　　Disadvantages: compared with the fuel version, the price is too high, there is no new energy subsidy, and there is no advantage in high-speed fuel consumption.

　　Compared with the fuel version of the same model, the hybrid version of oil and electricity has a more complicated structure due to the addition of a battery pack, so the cost is higher. Moreover, the hybrid model of oil and electricity will not enter the catalogue of new energy vehicles. To put it simply, the hybrid model is the same as the traditional fuel model and will not enjoy the national new energy subsidy.

　　For this reason, we specially selected several models that are popular in the market, namely Corolla, Camry, Accord and Sonata IX. As can be seen from their guide prices, the starting price of the fuel version and the price of the top model are lower than those of the hybrid version, and the price difference of the same configuration model is generally around 30,000 yuan, which makes consumers reluctant to buy more expensive hybrid models.

　　In addition, the hybrid gasoline-electric vehicle starts running under the condition of continuous and uniform high-speed driving. At this time, because the power of the motor is small, it can’t give full play to its advantages, so the fuel consumption when running at high speed is higher than that in urban areas. However, this is limited to the hybrid version itself, which is still more fuel-efficient than the fuel version at high speed.

　　Advantages: Zero emission in urban transportation, stronger motivation, license policy in some areas, and national and local new energy subsidies.

　　Plug-in hybrid models are equipped with larger battery packs. At present, the pure battery life of plug-in hybrid models sold in the market generally exceeds 50Km, which can basically meet the daily commute in urban areas. If you use pure electric mode to commute to work, you can achieve zero emission in urban commuting.

　　In addition, in recent years, China’s relevant policies have subsidized, encouraged and supported new energy vehicles, and there are new energy vehicle policies in Shanghai and Guangzhou. Plug-in hybrid vehicles can be licensed and enjoy national energy-saving subsidies, and these points have also become the most advantageous parts of plug-in hybrid vehicles.

　　Disadvantages: charging piles are needed. Fuel consumption is higher when the battery is dead.

　　The picture comes from the Internet.

　　When the battery is fully charged, you can commute as a pure electric vehicle. But when the battery has no battery, it needs a charging pile to charge it. Although there are many charging piles in first-tier cities, the growth rate of these infrastructures is relatively slow. In addition, the proportion of consumers who own private charging piles is still too small, and charging has become a problem for many new energy owners.

　　For this reason, many owners of plug-in hybrid vehicles only run it as a traditional fuel vehicle. However, because plug-in hybrid vehicles are loaded with large-capacity battery packs, they weigh hundreds of kilograms compared with traditional fuel vehicles, so under the same engine displacement, the acceleration time is slower and the fuel consumption is higher.

　　The schematic diagram shows BYD Qin Pro fuel version.

　　Let’s take BYD Qin Pro fuel version and Qin Pro DM dual-template models as examples. The kerb quality of Qin Pro fuel version 1.5TI dual clutch version is 1360Kg；; The kerb mass of Qin Pro DM double-template model is 1690Kg, and the difference between the two cars is 330Kg, which is equivalent to the weight of four adult males. It can be seen that when the battery is dead, it is equivalent to driving with full load, and the power performance and fuel economy will inevitably decline.

　　In the current form, the biggest drawback of new energy vehicles lies in the charging speed and cruising range. When the battery capacity reserve and charging technology can not reach the convenience of traditional fuel vehicles, it is wiser to choose hybrid models of oil and electricity and plug-in hybrid models.

　　Then, if you want to make a choice between hybrid electric vehicles and plug-in hybrid electric vehicles, I personally recommend hybrid electric vehicles besides the policy of sending licenses to local plug-in hybrid electric vehicles. Because this kind of vehicle has the same convenience as the transmission fuel vehicle (just refuel), and it has a great improvement in fuel economy and driving quality compared with the traditional fuel vehicle, so at present, the hybrid version of the vehicle has more advantages.

　　In order to thoroughly implement the decision-making arrangements of the CPC Central Committee and the State Council, conscientiously implement the notice requirements of the General Office of the Beijing Municipal Government on Several Measures to Continue to Increase the Assistance of Small and Medium-sized Enterprises and Accelerate the Recovery and Development of Difficult Enterprises (No.14 [2022] of Beijing Municipal Government), make overall plans for epidemic prevention and control and economic and social development, effectively reduce the impact of epidemic prevention and control on the production and operation of small and medium-sized enterprises in our region, and actively help difficult enterprises in the service sector to tide over difficulties and resume development, the implementation guidelines are specially formulated and issued.

　　First, reduce the burden on small and medium-sized enterprises

　　(a) the implementation of value-added tax refund at the end of the period.

　　1. Extend the policy scope of full monthly refund of incremental VAT tax allowance for advanced manufacturing industries to qualified small and micro enterprises (including individual industrial and commercial households). The stock tax allowance for qualified micro enterprises will be refunded in full from April 2022, and the stock tax allowance for qualified small enterprises will be refunded in full from May 2022, and the incremental tax allowance will be refunded in full from April 1, 2022.

□ Liu Weijun

Since December 1st, the Measures for Joint Punishment of Telecommunication Network Fraud and Related Crimes (hereinafter referred to as the Measures) issued by the Ministry of Public Security in conjunction with the National Development and Reform Commission, the Ministry of Industry and Information Technology and the People’s Bank of China have been implemented. The Measures make specific provisions on the disciplinary principles, disciplinary objects, disciplinary measures, disciplinary procedures and complaint verification of telecommunication network fraud and its related illegal crimes.

In recent years, telecommunication network fraud has become one of the main types of crimes faced by China and many countries. In this regard, China has continuously intensified its efforts to crack down on telecommunication network fraud and related crimes. Especially after the promulgation of the anti-telecommunication network fraud law, relevant functional departments have taken various comprehensive measures to actively carry out anti-fraud in the whole society, all employees and the whole process, and achieved outstanding results. The number of cases has been declining, and the number of interceptions and the detection rate have been rising. Not long ago, the Supreme People’s Procuratorate and the Ministry of Public Security launched the fourth batch of eight mega-cross-border telecommunication network fraud cases for joint supervision.

However, due to the cross-border nature of telecommunication network fraud and related crimes, and the support of huge black and gray industries at home and abroad, related crimes are always in a high-level operation state. Therefore, to eradicate telecommunication network fraud and its related illegal crimes, we should not only attack head-on, put out open flames and reduce the stock of crimes, but also take drastic measures to further increase punishment to reduce the increase of crimes.

The promulgation of the "Measures" has provided important support for multi-department collaborative governance of telecommunication network fraud and related illegal crimes. Synergy, first of all, is manifested in the diversification of governance subjects, which requires all departments and institutions responsible for the governance of telecommunication network fraud to do their part to ensure that telecommunication network fraud and its related illegal crimes are intervened, intervened or blocked by corresponding public power at all stages of occurrence, development and fission. Because the crime governance itself is extremely complex, it requires that the supervision should not be absent, but also requires all subjects to strengthen the cohesion and cooperation to ensure that the governance measures support each other and form gains, instead of going their own way, so that the implementation effect will be derogated from each other. Joint punishment is undoubtedly a good solution to the problem of convergence and cooperation.

According to the "Measures", joint punishment first needs to be determined by a criminal referee or by a public security organ at or above the municipal level, and then by sharing information about the joint punishment object, other regulatory authorities will implement financial punishment, telecommunication network punishment and credit punishment respectively according to their functions and powers. These three disciplinary measures work closely together to form a closed-loop supervision and are committed to eliminating the ability and opportunities for recidivism. This kind of "combination boxing" based on information sharing and collaborative supervision of various departments is more effective and lasting in restricting and punishing dishonesty than a single disciplinary measure implemented by a single department.

The "Measures" is an important symbol of the legalization and standardization of disciplinary actions. Supervision cannot be absent, but it cannot be offside. According to media reports, in the practice of anti-fraud, there have been some "extraordinary governance measures" in some places. For example, some provincial and municipal operators once turned off answering overseas calls and receiving overseas SMS services by default; "Threaten" to cancel the household registration of telecom network fraud suspects who are persuaded not to return, and impose restrictions on enrollment and suspension of social security on their families; Small remittances between relatives of residents need to be certified by the police station, and so on. Although some of these measures are not intended to punish, their effects are the same as punishment, and the identification of disciplinary objects is random and disorderly. After such measures were reported by the media, they aroused strong public concern and caused adverse social impact.

The "Measures" clearly define the recognition according to law and excessive punishment as the implementation principles of joint punishment, strictly control the scope of disciplinary objects, and give the final recognition right of atypical disciplinary objects to public security organs at or above the provincial level, which restricts the disciplinary behavior of governance subjects from both substantive and procedural levels. The "Measures" also expressed respect and concern for the basic needs of people’s livelihood, such as allowing disciplinary objects to apply for retaining a phone card that is not involved in the case, and establishing the maximum continuous execution period and the automatic termination system when the punishment expires.

Overall, joint punishment is an integral part of the comprehensive management system of telecommunication network fraud crimes, and the introduction of relevant joint punishment measures will help to fill the gaps in the governance ecology of telecommunication network fraud crimes. Sun Simiao Ceng Yun, the "King of Medicine": "Eliminate the disease that has not started, treat the disease that has not been cured, and treat it before nothing happens." The same is true for the management of telecommunication network fraud and illegal crimes, which should not only cure the disease, but also prevent the disease. Joint punishment of offenders will undoubtedly help to deter potential offenders and make them "afraid to commit" and "unable to commit". Considering that the disciplinary measures stipulated in the Measures will have a great impact on the lives of the parties concerned, it is necessary to be cautious in application and guard against abuse. Therefore, it is necessary to improve relevant relief measures as soon as possible and clarify how to pursue responsibility for wrong disciplinary actions. In other words, the supervision of the joint disciplinary measures itself is also an unavoidable responsibility for the management of telecommunication network fraud and its related illegal crimes.

　　Wuzhen was born of water, and lived by water. After autumn, it was fascinating to walk in the southern water town of Jiangnan, with the bluestone slabs, black tiles and white walls and rippling rivers in the ancient town. Nowadays, this Millennium-old town has been injected with the genes of the Internet and transformed into a world-famous Internet town. The rapid development of Wuzhen is also a microcosm of the development and progress of China’s communication technology and Internet industry.

　　On October 18th, the 6th world internet conference "Light of the Internet" Expo opened as scheduled. At the exhibition, China Mobile’s exhibition area with the theme of "5G+, unlimited possibilities in the future" became the biggest attraction of this conference. China Mobile Zhejiang Company has integrated and displayed more than 100 innovative and practical projects in the past one year, which not only shows how 5G can promote industrial digitalization, but also shows how 5G can meet the needs of a better digital life for all walks of life.

　　The reporter went to the "5G+ Ecology" section of China Mobile Exhibition Area, where the highlights include 5G+8K live broadcast, 5G+ remote driving, 5G+ smart fishing, 5G+ intelligent manufacturing, 5G+ smart medical care, 5G+ police investigation and so on. Here, you can see how 5G smart fisheries can intelligently monitor water quality and automatically feed fish. You can also see how mobile 5G can empower intelligent manufacturing and reduce costs and increase efficiency for enterprises. On the smart road of Wuzhen, long-distance driving has become a reality, and unmanned vehicles have shuttled back and forth on the road. A picture full of science and technology constitutes a new picture of smart Wuzhen.

　　"The above projects have achieved application results in related industries. For example, in the radio and television media industry, Zhejiang Mobile has jointly launched dozens of 5G live broadcasts with Zhejiang Radio and Television and Hangzhou Radio and Television; In the field of transportation, China Automotive Research Institute and Geely Automobile have actually deployed autonomous driving application scenarios based on 5G networks in Wuzhen; In terms of intelligent manufacturing, we will see the practical application results of 5G+ industrial manufacturing solutions in Jiaxing Xinfengming, Hangzhou Turbine, Shaoxing Jinggong Technology and other enterprises. " The on-site staff said.

　　5G+ fishery, creating a modern and intelligent fishery farming model

　　The underwater high-definition camera sends back high-definition pictures of underwater terrain and fish schools in real time through the 5G network, and the smart fishery cloud platform can diagnose the health status of fish schools in real time according to the pictures, and give an alarm for unexpected situations; The water quality can be monitored through the intelligent cage and various sensors in the cage, and the data such as pH value, dissolved oxygen and water temperature in the growth environment of fish can be adjusted in real time. With the low delay of 5G, the intelligent fish detector can control the start and stop of the fish detector in real time during the automatic cruise, and the bait feeding equipment can also be controlled in real time during the intelligent feeding process.

　　This is the development scene of 5G smart fishery. It is reported that in Huzhou, Zhejiang, China Mobile, together with Zhejiang Qingyutang Agricultural Technology Co., Ltd., Zhonglian Zhike and other partners, is carrying out the pilot work of smart fishery. Based on the characteristics of large bandwidth, low delay and wide coverage of 5G network, the functions of underwater survey, line setting, fish monitoring, water quality detection and intelligent feeding of offshore/pond farms are realized through intelligent terminals such as fish detectors, high-definition cameras, various sensors and intelligent cages, which are effective.

　　5G smart police investigation, science and technology to strengthen police for the benefit of the people

　　In the exhibition area, the application of this 5G smart police investigation attracted the attention of reporters. Only the interpreter said: Once a criminal case occurs, we can use the module of "5G Assisting Contact Police in Site Disposal and Site Protection" to provide scientific assistance to the victims under the remote guidance of remote professionals, and do site protection according to the background command center to ensure the integrity of the case site. The module of "Indoor and Outdoor Synchronous 3D Modeling Based on 5G Transmission" is used to synchronously scan the UAV’s peripheral environment and indoor accurate 3D scanning, and the modeling data can be returned in a few minutes through the 5G network, so that the key information of trace material evidence can be marked in the 3D space scene, and the indoor and outdoor 3D rapid modeling of the crime scene can be realized, and the real scene can be restored to the greatest extent.

　　According to reports, in 2019, the "5G-based Public Security Online Survey" project jointly created by Zhejiang Mobile and Lishui Public Security Bureau was officially launched and quickly applied. Industry-leading 5G technology and three-dimensional modeling technology realize all-time and all-factor online exploration of the case site.

　　Praise this application, and 5G technology will surely become a sharp weapon in the construction of "Safe China and Safe Zhejiang" to ensure long-term social stability.

　　Through the on-site display, we saw a brand-new scene of 5G smart education: through a private network, a large basic platform and N-type core applications, we presented a lifelong education system covering the whole life cycle of children, K12, universities and vocational education.

　　For example, Zhiyun Lab of Zhejiang University cooperated in Xixi, Yuquan, Zijin Port and other campuses, and 5G wisdom education realized interactive classroom, VR teaching live broadcast and AR-assisted teaching; In Cai He Experimental School, one-to-many virtual reality teaching can be realized, and the "immersive experience" allows students to deepen their understanding of the course; In the VR classroom of Times Primary School, students carry out scientific experiments, celestial science and scene experience education, so that teachers and students from different spaces can gather together in the virtual space to experience knowledge tour, artistic creation and game adventure together. "5G+VR Art Maker" allows students to create tools through VR painting, carry out bold 3D space graffiti, and convert works into objects through 3D printers. In addition, NB direct drinking water system, VR garbage sorting education game, 5G remote calligraphy, AR fitting mirror and other 5G educational applications can be described as eye-opening. Through the characteristics of low latency and large bandwidth of 5G, an immersive VR teaching resource platform is built to make children learn easily and happily. 5G smart education is becoming the direction of quality education in the future.

　　It is understood that through 5G technology, the smart medical system represented by "remote B-ultrasound" and "remote first aid" is becoming a reality. At present, Zhejiang Mobile and the Second Affiliated Hospital of Zhejiang University School of Medicine have built the first 5G remote first aid command center in China, which integrates remote B-ultrasound, VR diagnosis and treatment, remote video interaction, remote first aid platform, drone logistics and other systems based on 5G network, winning valuable rescue time for patients and creating a green channel for first aid.

　　Through the intelligent monitoring of 5G intelligent three-dimensional emergency network and AI technology, doctors can identify sudden illness and allocate emergency resources. The 5G ambulance sends the patient’s vital sign data back to the hospital in real time, and the hospital team monitors and guides them in real time, so as to prepare for rescuing patients in hospital in advance. At the same time, the vehicle-mounted drone can quickly transfer emergency drugs, blood and samples under the precise navigation of 5G. By using VR technology and remote B-ultrasound technology, experts can realize real-time remote guidance no matter where they are, and the emergency team can immediately put into rescue after the patient arrives at the hospital. After the patient is discharged from the hospital through the diagnosis and treatment of the specialist team, he can make online follow-up and consultation through the Internet hospital.

　　On the 5G ambulance, the doctor of the Second Affiliated Hospital of Zhejiang University School of Medicine told reporters: "With 5G technology, medical staff can send the patient’s B-ultrasound, electrocardiogram and other information back to the hospital in the ambulance, and can also pass the blood samples transported by drones in advance to judge whether the patient needs surgery. This gives us a weapon to take back the patient’s life from the hand of death. "

　　The Model 21 0 is a pure all-terrain off-road vehicle with an iconic three-ribbed chrome grille and a retro design that has become a symbol of its era. The G500 maintains its unpretentious retro style, interspersed with classics. But the more prominent front bumper, new side mirrors and wheel hub styling make it more dynamic and aggressive.

　　The 21 Mercedes-Benz G500 has a square body, a non-load-bearing body with a trapezoidal architecture, three 100% differential locks, and a low-speed off-road drive mode. These classic off-road elements will never fade. At the same time, the designer hopes to further improve the off-road performance in terms of data indicators. To this end, the new one has a higher ground clearance (the minimum ground clearance is increased by 6mm, reaching 241mm.), a larger wading depth (the wading depth reaches 700mm, an increase of 100mm than in the past.), a larger approach angle and departure angle. Approach angle 31 °, departure angle 30, both increased by 1 °

　　Many people can’t help but give a thumbs up to the 21 Mercedes-Benz G500. It is a classic legend in the history of off-road vehicles. It has maintained the same face for more than 30 years and is known as the master of the off-road field. That square design style gives it a very obvious character in the entire SUV market. Mercedes-Benz G500 has improved some details. The most obvious change is to add the popular LED daytime running light design. At the same time, it adopts a new mirror shape, while the tail is basically unchanged, retaining the simple and atmospheric style of the old model. Retain retro elements while adding fashionable and popular colors.

　　The 21 Mercedes-Benz G500 has been newly remodeled with a double 12.3-inch giant screen full of technology. The trend of air conditioning has also been changed to a redesigned barrel, which greatly enhances the sense of luxury and technology. The body size is 4764 * 1867 * 1954, the front and rear wheelbase is 2850mm, the minimum ground clearance is 205mm, the fuel tank volume is 96L, the fuel consumption is about 14.5L in the urban area of 100 kilometers, and the high speed is about 11L. The strong wedge-shaped feature and the eye-catching Mercedes-Benz logo make it feel his unrestrained gas when it is still.

　　The 21 Mercedes-Benz G500 is equipped with a 4.0L dual-supercharged V8 engine, with a 7-speed automatic gearbox, with a maximum horsepower of 422 horsepower and a maximum torque of 610N/m. The body size is 4764 * 1867 * 1954, the front and rear wheelbase is 2850mm, the minimum ground clearance is 205mm, the fuel tank volume is 96L, the fuel consumption is about 14.5L in the urban area of 100 kilometers, and the high speed is about 11L. The strong wedge-shaped features and the eye-catching Mercedes-Benz logo make it feel his unrestrained breath when stationary. However, these do not mean the loss of the Mercedes-Benz G500’s road performance. When driving the nearly three-ton body, it still has a good result of 0-100km/h acceleration of 10.2 seconds.
