People’s Daily Online, Beijing, December 10 (Reporter Qiao Yeqiong) Today, the National Health and Wellness Commission held a press conference to introduce the prevention and treatment of respiratory diseases in winter and answer questions from reporters.

　　At the meeting, a reporter asked whether the flu vaccine should be continued if the flu-like symptoms have already appeared, but they have not been diagnosed and recovered by themselves. When should I be vaccinated?

　　In this regard, Xia Gang, director of the Department of Health and Immunity of the National Bureau for Disease Control and Prevention, said that if flu-like symptoms have already appeared, it is still recommended to continue to vaccinate against influenza after being diagnosed and recovering.

　　Xia Gang explained that, first, the symptoms of respiratory tract infection are not specific, and flu-like symptoms such as fever and headache may occur in various pathogenic infections. However, these symptoms are not necessarily caused by influenza virus, but also by other pathogens, the most common being the common cold. Second, there are many types and subtypes of influenza virus that can cause epidemic. For example, there are both A and B, and in A, there are both H1N1 subtype and H3N2 subtype. After being infected with a certain type or subtype, there may be the risk of being infected with other types or subtypes. Influenza vaccine is a multivalent vaccine covering many different types and subtypes, which are commonly used trivalent and tetravalent vaccines. If you are vaccinated after being infected with a certain type of influenza, which contains other types of influenza components, you can still play a role in preventing this type of influenza.

　　Xia Gang said that in addition, in the same epidemic season, different types and subtypes are usually prevalent together. For example, at present, influenza A (H3N2 subtype) is the main strain, followed by influenza B. In the past, there have been cases in which the dominant strains gradually changed from one type to another in the same epidemic season. Therefore, even if flu-like symptoms have appeared recently, it is recommended to get flu vaccine as soon as possible after recovery, especially for key groups such as the elderly. Vaccination can reduce infection and reduce the risk of severe illness and death.

　　Consumers who are used to scanning the WeChat "face-to-face QR code" collection code now have new choices.

　　On January 13th, Bank of China announced its cooperation with China UnionPay and Tenpay, taking the lead in realizing the payment function of mobile banking scanning WeChat "face-to-face QR code" and becoming the first bank to realize mutual recognition and scanning with WeChat. On the same day, the Bank of Communications also announced that it has achieved interoperability with WeChat QR code payment.

　　In an interview with the Economic Daily, the relevant person of China Bank pointed out that it is a clear requirement of the People’s Bank of China’s financial technology development plan to realize the interconnection of scanning codes. For merchants, it can effectively integrate complicated two-dimensional code table cards to realize one-code communication; For customers, there is no need to identify and distinguish WeChat QR code, Alipay QR code and UnionPay QR code, and you can scan the code payment by opening the APP to achieve a sweeping.

　　With the development of interconnection, more two-dimensional code payment transactions will be settled through UnionPay and Internet Link, which will be more standardized and unified, conducive to risk information sharing and risk identification, and conducive to the overall management and monitoring of regulatory authorities, making the entire payment system more secure.

　　The reporter learned that at present, customers of Bank of China and Bank of Communications can complete the payment by scanning the QR code of WeChat payment using the mobile banking of these two banks in pilot areas such as Fuzhou, Ningbo and Jinan, and it is expected to be fully promoted soon.

　　Since 2019, the regulatory authorities and the industry have been promoting the development of interconnection standards for bar code payment, so that third-party payments such as Alipay and WeChat payment can be interconnected with scanned code payments such as QR codes developed by UnionPay. In September 2019, the People’s Bank of China announced the FinTech Development Plan (2019— In 2021), it is clearly proposed to promote the interconnection of bar code payment, study and formulate the technical standards of bar code payment interconnection, unify the coding rules of bar code payment, build the technical system of bar code payment interconnection, break through the barriers of bar code payment service, and realize mutual recognition and mutual scanning of bar code logos of different apps and merchants.

　　It is worth noting that after interconnection, are banks different from before in controlling payment risks? In this regard, the relevant person of Bank of China said: "This interconnection transaction still follows the UnionPay standard two-dimensional code payment specification and the four-party business model, which is in line with the existing two-dimensional code payment limit and safety risk control requirements, and is basically the same as the original two-dimensional code payment in risk control."

　　In addition, from a technical point of view, the reporter learned that in the process of realizing interconnection, the main problem is how to realize mutual scanning and mutual recognition of two-dimensional codes of different standards and the transaction transfer through clearing organizations. At present, the pilot project of mutual scanning between Bank of China, Bank of Communications and WeChat is only the first step of interconnection, and the follow-up needs the joint efforts of regulators, UnionPay, Internet, banks and payment institutions to further promote the participation of various institutions in interconnection from the payment industry level.

　　[Core Aspect] The report of the 19th National Congress of the Communist Party of China puts forward new requirements for China’s economic development in the future. The main contradiction in our society has been transformed into the contradiction between the people’s growing need for a better life and the unbalanced development. Based on this transformation, we should make clear the development focus and reform orientation of building a socialist modern power. At present, China’s economic development and transformation presents a series of new characteristics. Standing at a new starting point of development, we should adhere to quality first and benefit first, take supply-side structural reform as the main line, promote quality change, efficiency change and power change of economic development, and continuously enhance China’s economic innovation and competitiveness.

　　From high-speed growth to high-quality development stage

　　The report of the 19th National Congress of the Communist Party of China made the judgment that "China’s economy has shifted from a high-speed growth stage to a high-quality development stage", which is a new major judgment in view of the new changes in the international and domestic environment, especially the new changes in development conditions, after the economic development entered a new normal. In the past 40 years since the reform and opening up, China’s economy has maintained a high-speed growth of nearly 10%, accounting for an increasing proportion of the global economy. This is mainly because the reform and opening up has formed an institutional mechanism to effectively encourage market players and make full use of international and domestic market resources, so that the "dividend" of China’s rich labor resources and high savings rate can be fully brought into play through the continuous pull of domestic and foreign demand.

　　With the continuous impact of the international financial crisis, the development environment and conditions at home and abroad have changed, and China’s economic development has entered a new normal. First, the recovery of the world economy is difficult and continues to be sluggish, and the pulling effect of external demand on China’s economy has obviously weakened; Second, the working-age population has continued to decline, and the relationship between labor supply and demand has changed. In the past 10 years, the wage level has been rising, and the cost advantage of manufacturing has rapidly weakened; Third, more emerging economies have accelerated the pace of industrialization, used their labor cost advantages to absorb manufacturing investment and joined the world market competition; Fourth, the upgrading of the domestic market demand structure has accelerated, consumers’ demand for high-quality agricultural products, manufactured goods and high-quality services has become more prominent, and the domestic supply side has not been able to meet the changes in the demand structure well, resulting in more and more high-end demand for high-quality agricultural products, high-end manufactured goods and high-quality services spilling over to overseas markets. More and more consumers in China go abroad to purchase consumer goods and high-quality food, and go abroad to study, travel and seek medical treatment.

　　The above-mentioned changes in development conditions have made China’s original growth model, which mainly relies on factor input, external demand and scale expansion, more and more obviously restricted. We must change the mode of development, optimize the economic structure, change the driving force of growth and change to high-quality development in accordance with the requirements put forward in the report of the 19th National Congress of the Communist Party of China.

　　First, the economic growth rate may gradually drop from the high-speed growth of about 9% in the past to about 6%. Mainstream research at home and abroad shows that the potential growth rate of China’s economy in the future is generally in the range of 6% to 7%. Considering that the proportion of China’s foreign trade in global trade has reached a high level, and the original low-cost competitive advantage is being lost, and considering the conditions such as the strengthening of ecological environment constraints, and the new kinetic energy formed by innovation is difficult to make an explosive breakthrough in a short period of time, it may be difficult for China’s economy to reproduce the high-speed growth in the past. It should be recognized that it is quite good to achieve a potential growth rate of 6% to 7%.

　　The second is to change to a development model that pursues high quality and high efficiency. To realize the sustained and healthy development of China’s economy, the fundamental way out is to promote the quality change, efficiency change and power change of economic development, which needs to continuously improve the quality of products and services of enterprises and improve their operating efficiency from the micro level. It is necessary to take the supply-side structural reform as the main line, accelerate the upgrading of industrial structure and the transformation of traditional industries, accelerate the development of high-quality modern service industries, increase the supply of high-end products and services, and continuously improve added value and competitiveness. Promote the development of new technologies, new products and new formats through innovation, especially by promoting the deep integration of the Internet, big data, artificial intelligence and the real economy, and promote cross-border integration and innovation, so that the potential and new kinetic energy formed by innovation and entrepreneurship will become an inexhaustible driving force for China’s economic growth and continuously enhance the innovation and competitiveness of China’s economy.

　　The third is to accelerate the market-oriented reform that is conducive to the market to play a decisive role in resource allocation. In pursuit of high quality and high efficiency, we must persist in giving full play to the decisive role of the market in resource allocation and reduce the government’s intervention in market resource allocation. It is necessary to further deepen the reform of the economic system, adhere to the orientation of marketization, speed up the construction of a market economic system with effective market mechanism, dynamic micro-subjects and moderate macro-control, give enterprises greater autonomy in investment and management decision-making, give full play to and stimulate the innovation power and creativity of market subjects, improve the efficiency of enterprise resource allocation from a micro perspective, and lay a foundation for improving the efficiency of resource allocation in the whole society from a macro perspective.

　　Building a modern economic system is a strategic goal.

　　According to the report of the 19th National Congress of the Communist Party of China, China’s economy has changed from a high-speed growth stage to a high-quality development stage, and it is in the key period of changing the development mode, optimizing the economic structure and transforming the growth momentum. Building a modern economic system is an urgent requirement for crossing the barrier and a strategic goal for China’s development. Building a modern economic system is a brand-new expression, and its main connotation is:

　　First, adhere to quality first and benefit first, take supply-side structural reform as the main line, vigorously promote quality change, efficiency change and power change of economic development, and strive to improve total factor productivity. After nearly 40 years of reform and opening up, China’s GDP has ranked second in the world, and the production scale of more than 220 major industrial products ranks first in the world. However, the problems of low quality and efficiency and weak growth momentum have become increasingly prominent. To change this situation, we must aim at improving quality and competitiveness, give full play to the decisive role of the market in resource allocation, encourage scientific and technological innovation and entrepreneurial innovation more effectively, accelerate the upgrading and efficiency improvement of traditional industries, improve the quality of products and services on the supply side, better meet the upgrading of domestic consumption structure, and achieve a higher quality and level of dynamic balance between supply and demand.

　　The second is to speed up the construction of an industrial system in which the real economy, scientific and technological innovation, modern finance and human resources develop in coordination. Accelerating the development of the real economy is an important task of building a modern economic system and the focus of economic development. We should focus on the real economy, accelerate the construction of a manufacturing power, and take the road of coordinated development and mutual support among the real economy, scientific and technological innovation, modern finance and human capital. In this process, it is necessary to strengthen the supporting role of scientific and technological innovation in the real economy, especially in advanced manufacturing, and give full play to the role of the state in basic research and applied basic research in technological innovation; Strengthen the service function of finance to the real economy, and provide efficient, convenient, reasonable and diverse financing services for the real economy, especially direct financing services such as venture capital and equity investment; Strengthen the cultivation of human capital and provide more labor with higher professional quality and skills for the upgrading of the real economy.

　　The third is to speed up the construction of a market economic system with effective market mechanism, dynamic micro-subjects and moderate macro-control. Effective market mechanism is to improve the socialist market economic system, focus on improving the property rights protection system and the market-oriented allocation of factors, and achieve effective property rights incentives, free flow of factors, flexible price response, fair and orderly competition, and survival of the fittest. This is the necessary institutional guarantee for achieving high-quality and high-efficiency growth. The vitality of micro-subject means to respect the dominant position of enterprises, continue to deepen the reform of commercial system, fully implement the negative list system of market access, implement the autonomy of enterprise management decision-making, deepen the reform of state-owned enterprises, support the development of private economy, and cultivate more world-class enterprises with global competitiveness. The core of moderate macro-control is to innovate and improve macro-control, give play to the strategic guiding role of national development planning, and improve the coordination mechanism of financial, monetary, industrial and regional economic policies. When implementing macro-control, the government should conform to the laws of the market, grasp the boundaries and relations between the government and the market, and do not be absent or offside, so as to better play the role of the government.

　　Deepening supply-side reform is the fundamental solution.

　　Deepening the structural reform of supply side is the key task of building a modern economic system, which is the fundamental solution to the structural problems existing in the supply side of China’s economy.

　　The contradiction between the irrational supply-side structure of China’s economy and the failure to meet the upgrading of domestic demand structure is more prominent. In recent years, the supply-side structural reform with the emphasis on de-capacity, de-inventory, de-leverage, cost reduction and short-boarding has achieved positive results, but overall, the supply of high-quality products and services in China still does not meet the requirements of demand upgrading and refinement, and the industrial competitiveness needs to be further improved. Therefore, we must focus on the real economy, especially the manufacturing industry, take improving the quality of the supply system as the main direction, continue to deepen the structural reform of the supply side, improve the quality of the stock supply, and expand the high-quality incremental supply.

　　It is necessary to encourage all walks of life to carry out quality improvement actions and continuously enhance the quality advantage of the economy. Accelerate the development of advanced manufacturing and modern service industries, cultivate a number of world-class advanced manufacturing clusters, and promote China’s industries to move towards the middle and high end of the global value chain. Focusing on the middle and high-end consumer demand, we will cultivate new growth points and form new kinetic energy in the fields of innovation-led, green and low-carbon, sharing economy, modern supply chain and human capital services, promote the deep integration of the Internet and the real economy, and give better play to the integration and innovation effects of big data, cloud computing, artificial intelligence and the real economy. Support the optimization and upgrading of traditional industries, aim at international advanced standards to improve product technology, process equipment, energy efficiency and environmental protection, improve product quality and added value of traditional industries, especially strengthen high-end manufacturing capabilities in the fields of basic processes, basic materials and basic components. In addition, we will continue to strengthen the construction of infrastructure networks such as water conservancy, railways, highways, water transport, aviation, pipelines, power grids, information, logistics, etc., strengthen the interconnection and convergence between infrastructure networks, and give full play to the integrated service effect and support for the real economy.

　　We must continue to adhere to de-capacity, de-inventory, de-leverage, reduce costs, make up shortcomings, optimize the allocation of stock resources, and expand high-quality incremental supply. It is necessary to improve the real estate control measures and optimize the supply structure of the real estate market. Further measures should be taken to reduce the overall debt leverage ratio, especially to effectively control the debt risk of local governments. In terms of making up the shortcomings, it is necessary to strengthen the prevention and control of the discharge of important pollutants in key areas and focus on solving outstanding environmental problems. Further improve the long-term mechanism for poverty alleviation, adhere to precise poverty alleviation and precise poverty alleviation, complete the poverty alleviation goals and tasks that have been clearly defined, and achieve poverty alleviation and poverty alleviation. In addition, based on the long-term, we should strengthen the short-board construction, including insufficient innovation ability, inefficient financial services, imperfect social security system, insufficient maintenance of unified market and insufficient accumulation of human capital, invest resources, improve systems and mechanisms, and prevent short-board from becoming a constraint to sustained and healthy economic development.

　　Entrepreneurs are the main force to promote supply-side structural reform, revitalize the real economy, and also promote innovation and development. We should better stimulate and protect entrepreneurship, stabilize entrepreneurs’ long-term expectations, and support entrepreneurs to innovate and start businesses, so that they can be rooted in the long-term development of China’s economy. High-quality development is inseparable from high-quality workers. It is necessary to increase the cultivation of human capital, build an army of knowledge-based, skilled and innovative workers, promote the spirit of model workers and craftsmen in the whole society, form a glorious social fashion of labor and a professional atmosphere of Excellence, and improve the economic and social status of ordinary workers.

At the Chengdu Auto Show, which opened on August 30th, BYD 2025 was officially launched. Four new models were launched, including three two-wheel drive models and one four-wheel drive model. The price range remained the same as that of 2024 models, ranging from 189,800 yuan to 249,800 yuan.

As an annual redesigned model, although the price range of the 2025 model remains unchanged, because the entry version of the 2024 model (beyond model) was cancelled, in fact, the price of the 2025 Song L EV was lowered by 10,000 yuan.

In addition to lowering the price, the 2025 model also added aurora blue paint and Xuan Kong gray interior color. In terms of intelligence, some models are also equipped with the "Eye of God" advanced intelligent driving assistance system -DiPilot 100, which provides more than 30 functions such as driving assistance and parking assistance, including high-speed navigation, lane navigation, lane change, automatic parking, remote parking, 3D panoramic transparent images, side distance reminder, etc., to improve the driving safety and convenience of users in multiple scenarios.

In terms of design, the appearance and interior of the 2025 model remain the same as that of the 2024 model. The appearance of the hunting coupe creates an elegant and dynamic visual effect. The 15.6-inch central control panel, 10.25-inch full LCD instrument, 50-inch AR-HUD head-up display and 5.8-inch rear air conditioning control panel with a large area of suede material in the car have both a sporty atmosphere and a sense of technology.

　　Fifty years back in time, when cars were not yet popular, cars were a luxury and a status symbol for most people. Today, in this era where cars drive people to pursue a quality of life, cars have not only become a part of people’s lives, but also represent their own culture and favorite attitude towards life. Obviously, cars are not just a simple means of transportation, but also the best carrier for people to taste car fashion and enjoy car life.

　　The FAW Toyota Crown Land, while inheriting the excellent genes of the Crown brand’s continuous innovation and internal and external repair, also brings excellent driving quality and all-round safety protection under the TNGA architecture, bringing an ideal choice for those who are rational and sophisticated, pay attention to connotation, and can control changes in the new era. It can be said that the Crown Land is not just a car, but also the best partner to witness them achieve their life goals and lead their families to a better life.

　　The crown is repaired inside and outside, dynamic but noble

　　A person’s success is no accident, and there must be admirable sweat and hard work behind it. Especially in today’s fast-paced society, only those who are decisive, rational, and self-improvement in order to achieve their goals can step by step towards success.

　　Just like the crown land put both inside and outside, it not only has a dynamic and domineering high value, but also has a quiet and luxurious interior space. In terms of appearance, the crown land put inherits the noble and atmospheric design aesthetics of the "crown", and integrates the sports elements of the TNGA family. The hexagonal honeycomb middle net, dynamic and fashionable, and the huge "crown" logo is inlaid in it, showing the innate noble temperament; the large-mouth horizontal bar-like lower grille combined with the penetrating silver decorative strip below, with the tusk-like air inlet holes on both sides and the sharp upward three-eye LED headlights, makes the entire front face look more powerful and domineering, even in a static state, the innate king’s demeanor can be seen at a glance. With the launch of the Crown Land Drop 2.0T, the door welcome light and wheel hub anti-theft nuts with the Crown logo have been added to all series, further demonstrating the noble temperament of the Crown Land Drop.

　　Coming into the car, the crown landing has an innate delicate design and quality style. The instrument panel and interior lining and other details are all wrapped in leather fabrics, so that all the areas that the occupants can reach in the car have soft materials to deal with cushioning, and the sense of high-end is oncoming; the ergonomically designed seat has good comfort and wrapping, and the riding experience lives up to the name of the crown. At the same time, inheriting the classic crown quiet gene, the front windshield and front side rows are made of soundproof glass, and the body is equipped with sound insulation materials and vibration damping materials in a wide range, so that every moment in the car can be enjoyed quietly and comfortably.

　　Unflappable, calm driving, crown land release dual power to meet more needs

　　"Mount Tai collapses in front of you but remains unchanged" is one of the qualities that every person who aspires to success must possess. Because on the road to success, it is inevitable to encounter difficulties or unpredictable changes of one kind or another, and in the face of these difficulties and changes, only by remaining calm can we calmly control them.

　　Just like the Crown Land Discharge, it provides two sets of power systems to meet people’s different driving needs. Among them, the Crown Land Discharge 2.5L HEV is equipped with Toyota’s new generation TNGA 2.5L dual-engine hybrid system. Its 2.5L naturally aspirated engine has 41% thermal efficiency, and the comprehensive power of the system reaches 183KW. The NEDC comprehensive fuel consumption data is only 5.8 L/100Km (four-wheel drive version), which can be said to achieve a perfect balance between power and fuel consumption.

　　Matching it is an E-CVT transmission, which under the blessing of "hybrid black technology" PSD, brings surging power while making the power output more linear and smooth. And it is equipped with E-FOUR electronic four-wheel drive system and has a TRAIL one-click escape mode, which further enhances the vehicle’s passability and gives people a sufficient sense of security.

　　Crown Land 2.0T gasoline power is equipped with the newly developed TNGA 2.0L twin-turbocharged direct injection engine, with a maximum power of 182kW and a peak torque of 380N ? m, reaching the industry leader in power, quietness, economy and reliability. Standard 8-speed automatic (Direct Shift-8AT) gearbox, with multi-gear advantages and ideal gear ratio, has "four major advantages" such as faster start, smoother gear change, smoother acceleration, and more economical high speed, bringing users a smoother and more pleasant driving enjoyment.

　　In terms of four-wheel drive, the Crown Land Range 2.0T is equipped with an excelle****** dynamic torque vector control system and an AIM four-wheel drive integrated management system. AIM can comprehensively control the driving force, four-wheel drive, braking, steering and other functions according to different road surfaces and driving conditions, based on different driving modes, to ensure that the vehicle’s performance is fully exerted under all working conditions. The powerful DTV dynamic torque vector control system can achieve a torque distribution ratio of 100:0-50:50 before and after, and can also independently control the left and right rear wheels to achieve a torque distribution of 100:0-0:100, greatly improving the escape performance.

　　In addition, the Crown Land Release uses a front McPherson + rear double wisharm suspension combination, which makes the vehicle run stably, with light steering and good shock filtration, allowing you to enjoy a hearty driving pleasure whether in the city or outdoors. It can be said that the two sets of power systems of the Crown Land Release, whether dual-engine hybrid or turbocharged, are enough for you to ride calmly in any road conditions.

　　Large space, high safety, and a shared car life

　　A qualified and successful person not only has a strong sense of career, but also has a sense of responsibility to take care of the family. That is to say, while achieving career success, he must also be able to lead the whole family to enjoy a better life.

　　Just like the Crown Land Pad, it has a high value and high performance, but also has a large space. The super 5m heroic body and the long wheelbase of 2850mm make the Crown Land Pad have a wide and comfortable cockpit. In particular, the sliding distance of the second row of seats is 180mm, and the adjustable range is wider, so that the second and third rows can have more abundant adjustment space. With a 520mm deep suitcase, it can meet and expand different riding and loading scenarios.

　　In terms of safety, the Crown Land Displacement uses a TNGA high-rigidity lightweight body and comes standard with 7 airbags, including the main/passenger airbags, front side airbags, front/rear head aircurtains, and knee airbags, which can be described as all-round protection. In terms of active safety, the Crown Land Displacement comes standard with a new generation of Toyota Safety Sense smart safety, providing a mobile safety fortress for the whole family.

　　conclusion

　　As the first flagship seven-seat SUV after the rejuvenation of the Crown brand, the Crown Land Drive is not only repaired inside and outside, but also equipped with a leading dual power system of "turbocharged + dual-engine hybrid", which brings people a better car life with excellent driving performance and safe and comfortable driving experience. It can be said that the Crown Land Drive is not only one car, but also the best partner for the journey of life.

　　Recently, Harbin Housing Provident Fund Management Center officially launched "Harbin Housing Commercial Loan" and "Harbin Industry (provincial, agricultural reclamation, electric power, railway) sub-center housing provident fund loan" to automatically withdraw the provident fund to repay the loan on a monthly basis. At this stage, data docking and system testing are underway. At that time, the employees who pay the housing provident fund in Harbin only need to sign the Agreement on Monthly Withdrawal of Housing Provident Fund, and there will be no need to go to the window to go back and forth to withdraw the provident fund and repay the housing loan.The provident fund center directly transfers the extracted provident fund to the repayment card (discount) of the employee bank on a monthly basis through the business system for repayment of loans.

　　How did the virus originate? What are scientists doing in developing drugs against Covid-19? It is the top priority for Chinese researchers to develop effective clinical drugs for Covid-19, improve the cure rate and reduce the mortality rate. On February 15th, Zhang Xinmin, director of the Biological Center of the Ministry of Science and Technology, introduced that the drug screening and treatment program had made positive progress at the press conference held by the the State Council Joint Prevention and Control Mechanism on the latest progress of drug research and development and scientific research in Covid-19. The Ministry of Science and Technology organized a national excellent scientific research team to screen more than 70,000 drugs or compounds by computer simulation screening and in vitro enzyme activity test. At present, The scientific research team has focused on a few drugs, and a number of drugs, such as chloroquine phosphate, lundixivir, and farpiravir, have successively carried out clinical trials. At present, some drugs have initially shown good clinical efficacy. This issue focuses on the origin of the virus, drug research and development, and psychological anti-epidemic.

　　The structure of most viruses is very simple. Basically, it is a shell made of protein wrapped with some genetic material, which is no different from dead things at ordinary times. Once infected cells, they inject their own genes into the host cells and use the host cells to replicate themselves to produce new viruses. Is the virus a living thing? Where did they come from? Below, let’s take a look at three hypotheses about the origin of the virus.

　　Hypothesis 1 Ancient macromolecules Some macromolecules, such as RNA, DNA and protein, begin to replicate themselves independently or cooperatively, and this stage can be called "molecular life". However, in a peaceful molecular life, there is a different kind, that is, some molecular life, including LUCA, the latest common ancestor of all living things, which has developed a structure that has changed the law of life, that is, cells. Cells with membrane structure can better protect delicate core macromolecules such as RNA and protein, which greatly enhances the adaptability of these organisms, which means that they will rub their original molecular life on the ground. There is a hypothesis (The Virus-First Hypothesis) that the virus is the "adherents" of the primitive molecular life world. This hypothesis was once very popular, after all, the structure of viruses is so simple, even crude, and their differences from cell life are so great.

　　Some viruses can form crystals after purification, which is unimaginable for cell biology. More solid evidence comes from "Virusoid", which is an RNA molecule. Pseudovirus can’t infect cells directly, but it can infect viruses. To be exact, it can copy itself and spread itself by hitchhiking when some viruses infect cells, which can cause some diseases such as human hepatitis D.

　　Hypothesis 2 The gene of "defection" Genes can also defect? Yes, in The Progressive Hypothesis, genes will do anything to keep themselves alive.

　　There is a small circular DNA called "plasmid" widely in bacteria. These genes are basically a group of wage earners and temporary workers. Bacteria can absorb them from the environment for their own use at any time, and they can also drive them away at any time.

　　In many bacteria, in addition to their original DNA, there are often some small fragments of circular DNA, which are called plasmids. So in the long evolution, some plasmids learned one thing: we should not work all our lives! These plasmids changed from wage earners to wage earners, which in turn hijacked their bacterial boss and took away all the nutrients of bacteria to replicate themselves. Over time, some plasmids become viruses.

　　Bacteria often suffer from a kind of virus infection called "phage". Some people think that phage comes from plasmid. The cells and bacteria of human beings and all animals and plants are very different. We all belong to "eukaryotes". There are no plasmids like bacteria in the cells, but there are still some genes waiting to move. They refused to stay on the chromosome, but jumped around in the nucleus, running to this chromosome for a while and running to that chromosome for a while. However, these naughty genes do have a name of sage like type — — Transposon (transposon)

　　According to the detection of molecular biology, many transposons have very similar gene sequences to viruses, and the mechanism of integrating themselves into the chromosomes of host cells is also highly similar. In particular, the "Retrotransposon" among them is almost as similar as some viruses, and the only difference is that these transposons cannot migrate from cell to cell like viruses.

　　However, the origin of viruses is still confusing here, because they don’t follow the evolutionary model of general organisms at all.

　　The general process of virus infection is: inject your own genes into the host cells, then use the host cells to copy your own genes, and make all kinds of materials needed to construct virus particles. Finally, manipulate the cells to package all parts of virus particles together with the virus genes into new virus particles and release them to infect other cells. But in this process, the virus is exchanging genes with various organisms all the time.

　　For example, when a virus directs a host cell to package virus particles, it sometimes packages some host cell DNA, or accidentally leaves a little bit of its own gene in the host cell. There is a gene in mammals to prevent the maternal immune system from attacking the fetus, that is, a virus accidentally landed in our cells more than 100 million years ago. When the virus spreads across species, it often leads to the transfer of genes from one species to another.

　　Hypothesis 3 Decaying cellular organisms. After entering the 21st century, a series of discoveries began to make scientists more aware that there are other possibilities for the origin of the virus.

　　In 2003, scientists discovered a very unreasonable virus — — "Mimivirus", the size of this virus has reached 0.4 to 0.5 microns, which is almost the same as bacteria under the microscope. The coronavirus that caused this epidemic is considered to be a relatively large type of virus, and its size is less than 0.1 micron.

　　In 2008, scientists discovered the second big virus, and named it "Mamavirus". Since then, one kind of "Giant Virus" has appeared in human vision one after another. By the time Pandoravirus was discovered in 2013, the record of the largest virus was even more than 1 micron.

　　Pandora virus, the largest known virus, looks almost the same as a bacterium.

　　Since then, the boundaries between viruses and some single-celled organisms have become blurred. For example, the structure and genes of Bacteroides virus are very similar to those of a single-celled organism called archaea. The only difference is that Bacteroides virus has lost a part of the key genes that independently complete cell division, so it has to parasitize in the cells of other organisms and use the cells of the host to grow and reproduce.

　　So there is the third hypothesis of the origin of the virus (The Regressive Hypothesis), which holds that the virus is essentially a degenerate creature. Some single-celled organisms gradually degenerate most of their cell structures in the long-term parasitic life, and finally become this "living dead" general appearance, and the flow like bacteroides virus is an archaea that has just begun to degenerate.

　　Why do deadly viruses always come from wild animals? Let’s analyze it from the perspective of evolution.

　　The "best" virus does not cause too serious symptoms (otherwise it will kill the host itself), but it should not be too gentle (after all, the host is often infected with other viruses at the same time, so it is still necessary to grab resources). Therefore, in the long evolution, this game will promote the virus to finally reach a certain tacit understanding with the host. For example, human beings and rhinoviruses that may cause the common cold belong to this relationship.

　　However, the virus will mutate, and some mutations will cause the host of the virus to change. Without the tacit understanding of long-term running-in between the virus and the new host, there will be the problem of "not paying attention to it", and some of them will bring fatal diseases to the host.

　　In the long-term evolution, human beings have reached a perfect tacit understanding with the viruses that accompanied them all the way from ancient ancestors, and the viruses from livestock, such as measles and flu, are not perfect, but they are somewhat tacit, so they rarely cause serious epidemics. Only the virus from wild animals has nothing to do with human beings, so almost all the diseases that caused the great plague came from wild animals. Therefore, I hope everyone can stay away from wild animals, including stray animals, and don’t raise or eat wild animals.

　　[Car History] When it comes to its classic models, I’m afraid there is no one who doesn’t know the name except the familiar ones. The Beatles laid a solid foundation for the Volkswagen brand, and Dave became the spiritual and material double pillar of the Volkswagen Group. Just like the popular saying that "with golf (), there will be all models of the public", golf has become synonymous with the public. Since its birth in 1974, after 39 years of development, today’s golf has evolved into the seventh generation. Although most people have already memorized the history of golf, it doesn’t prevent you from revisiting the legendary development history of this Volkswagen classic model again, and maybe you can gain something new.

The background of golf: replacing the exhausted Beetle (Volkswagen EA-276 prototype)

　　Although the Beetle has brought great honor and benefits to the public, it has not changed much since it was officially born in 1938. At the end of 1960s, the sales volume of the Beetle dropped sharply. Volkswagen knew that the exhausted Beetle could not meet the people’s demand for the "national car" in terms of technology and the utilization of the interior space, and the successor to develop the "national car" was officially put on the agenda. In 1969, two prototypes, EA-266 and EA-276, were born one after another. Because EA-266 was placed in the lower rear seat, it was quickly eliminated by the noise and smell from the engine, while EA-276 with layout was successfully promoted. The car was equipped with a 1.5-liter horizontally opposed four-cylinder engine with 44 horsepower, and its square shape was probably not very pleasing. This is the prototype of Volkswagen Golf.

Note: Many people mistakenly think that the name of Golf comes from Golf. In fact, the naming method of Golf follows the consistent style of Volkswagen, that is, many of its models are named after the wind, as we know, Santana and others, and Golf comes from a warm current in the Gulf of Mexico.

The First Generation Golf Mk1(Typ 17)——1974-1983
Classic, the first "hatchback"

　　In May 1974, the first generation of golf officially entered people’s sight. Compared with the slightly rigid shape of EA-276 prototype, the "origami" design concept put forward by Italian car designer Giorgetto endowed the first generation of golf with an indelible classic shape. Maybe you don’t like its square-headed, square-brained shape, but when you look at it again today, you will find that this simple line is so intriguing. The whole plastic air intake grille is inlaid with two round headlights, and the front bumper hanging on the front of the car is shaped like a chopstick. Although it is a new "national car", chrome decoration is still full of air intake grille, bumper edge and body waist line. (Click to enter the biography of Giorgetto, the master of automobile design)

　　The first generation golf adopted the same hatchback shape as the prototype EA-276, and the concept of "hatchback" was first applied by golf and introduced into the field of automobile design. Compared with the prototype, the angle of the trunk cover of golf is more inclined. "Chopsticks" are always a pair, not one. Except for the turn signals on both sides of the front bumper, the front and rear bumpers are strikingly similar in size and shape, and the prominent wheel eyebrows make their simple shape have a sense of hierarchy. The first generation of golf is divided into two types: two-door hatchback and four-door hatchback. Taking the golf hatchback version as an example, its vehicle size is 3705mm long, 1610mm wide, 1395mm high and 2400mm high, and its weight is only 790kg.

　　The interior design of the first generation golf seems a bit too simple as its modeling. The Volkswagen "Wolfsburg" logo was placed in the center of the two-spoke steering wheel. The left side of the double-barrel instrument panel was not a tachometer, but a "disguised" clock. The water temperature and fuel gauge were located at 12 o’clock and 6 o’clock respectively, and the right side was a speedometer. The only thing that can make people shine in the car is the silver plaque on the center console. A large area under the T-shaped area of the center console has been ruthlessly wasted. Interestingly, the gear sign is placed above the cigarette lighter near the co-pilot’s side. For beginners, this design will inevitably make people crazy.

　　The first generation of golf adopts the structure of front and back half. Compared with the previous "national car" Beetle, golf has been greatly improved in maneuverability and practicality. The configuration of the first generation golf can only be considered enough. All you can see in the car are simple and practical configurations such as radio, air conditioner and hand-cranked window. In addition, Volkswagen also equipped the first generation of golf with front wheel disc brake system and rear wheel drum brake system. These configurations may not be worth mentioning at present, but as the successor of the Beatles, the overall quality of golf is still satisfactory.

　　In terms of power, the first-generation golf, which was originally launched, was only equipped with a 1.1-liter inline four-cylinder engine, with a maximum of 50 horsepower and a maximum of 78 N m. Since then, Volkswagen has successively launched golf models with 1.3 liters, 1.5 liters, 1.6 liters, 1.7 liters, 1.5 liters and 1.6 liters. Among them, the 1.6-liter inline four-cylinder gasoline engine has a maximum power of 86 HP (63kW)/5600rpm and a maximum torque of 127 N m/3200 rpm, which is matched with the engine at 4, 5 and 3 speeds.

　　In March, 1975, the first generation of sports golf model-Golf GTI appeared, and it was officially listed in June, 1976. The first generation of GTI also has two models, three-door and five-door hatchback, for consumers to choose from. The original intention of GTI is to let consumers enjoy driving even if they buy economical cars. In order to be different from ordinary golf, GTI, as a sports model, has made some optimization in appearance details, the most obvious of which is a circle of red decorative lines on the periphery of the front air intake grille, with a black Volkswagen logo in the center, the "GTI" on the side is particularly conspicuous, and the front and rear bumpers are also chrome-plated. At the same time, the plastic black spoiler under the front of the car complements the black wheel eyebrows, which further highlights the exclusive sense of GTI.

　　Volkswagen has rendered the sporty atmosphere of the first generation GTI interior to the extreme. The monotonous two-spoke steering wheel on the regular version was replaced by a three-spoke competitive steering wheel with the logo of Wolfsburg. What about the clock on the left side of the original dashboard? For GTI, which pursues sports, the tachometer is more pragmatic. In order not to destroy the overall color of the interior, the silver center console panel has also been changed to black. Before, the sealed part under the center console was changed into a storage space. The oil temperature gauge on the left side below also reminds you at all times that this is a sporty car, and the forgotten clock is placed on the right side of the oil temperature gauge. The most exciting thing for fans is the Golf ball-shaped stopper. Is this to match the name of Golf? Who cares! What fans are after is an excellent feel.

　　A sporty appearance alone is definitely not enough for fans to pay for it willingly. The first generation GTI is equipped with a 1.6-liter inline four-cylinder naturally aspirated fuel injection engine, with a maximum power of 110 HP (81 kW)/6,100 rpm and a maximum torque of 140 N m/5,000 rpm. For a GTI weighing only 810kg, its acceleration time of 0-100km/h is only 9.2. Low vehicle weight, solid chassis and strong power make GTI known as "". With the success of the first generation of golf GTI, other manufacturers have also launched their own "small steel cannon" models, and golf has once again become the leader of the new trend in the industry.

　　The original intention of Volkswagen to launch golf GTI is only to participate in the competition. Volkswagen originally planned to produce 5,000 golf GTIs to meet the qualification of production cars stipulated by the competition. I never thought that the first generation of golf GTI would be sought after by fans as soon as it was launched, so Volkswagen continued to increase production to meet the market demand for this "small steel gun". Since its birth in 1975, the first generation of golf GTI has produced about 530,000 sets, which has since established GTI’s unshakable position.

　　As the sales of the first generation of golf are rising, it has increased the confidence of the public in developing new models. In 1979, the golf convertible version derived from the first generation of golf was officially unveiled. The birth of the golf convertible made people realize that the original economical car can be so romantic. The first-generation golf convertible version uses a soft-top convertible that can be folded manually, and the horizontal position of B-pillar can effectively increase the strength of the whole vehicle. Volkswagen has made some modifications to the front and rear bumpers of the first-generation golf convertible version, and the black plastic decoration added to the rear license plate position makes the rear of the car look less monotonous.

　　In 1975, Volkswagen introduced the first generation of Golf to the North American market and assembled it in the Volkswagen westmorland factory in the United States. The American version was named Rabbit instead of Golf. In order to comply with safety regulations, Rabbit has adopted an "extended" bumper, which is also a major feature of European models entering the North American market. Due to the use of soft suspension and too cheap materials, the quality of Rabbit is extremely unstable, which also makes the German public angry. In 1980, North American Volkswagen introduced a modified model of Rabbit, which changed the original round headlights into a square style, while the convertible version of Rabbit still used round headlights.

　　In 1981, Volkswagen launched the Rabbit version, a derivative model of Rabbit. The car adopts a double-door design, and the wheelbase is lengthened and then equipped with a rear cargo compartment. If you are used to the ordinary version of the car and look at the pickup version, you will find it very different. The dimensions of the Rabbit pickup truck version are 4380mm long, 1640mm wide, 1490mm high and 2625mm wheelbase. In 1983, Volkswagen introduced Rabbit GTI. Unlike Golf GTI, Rabbit GTI equipped with a 1.8-liter inline four-cylinder engine has only 91 horsepower (67kW), which obviously does not meet the definition of "small steel gun". Rabbit GTI exported to Canada is all made in Germany, equipped with a 110 HP (82kW) 1.8-liter inline four-cylinder engine.

　　In 1983, Volkswagen introduced the first generation of small modified golf models. The most striking feature of the modified golf is the "four-eye" headlights, which are more full in taillight style and more in line with the trend at that time. Interestingly, the first generation of golf convertible was not modified until 1988. Except for the four-round headlights, the new bumper with the same color as the car body is more full, and the application of side skirts makes the visual effect of the whole car lower. Many improvements have made the modified golf convertible look energetic.

　　Compared with the North American version of golf, the South African version of golf-Volkswagen Citi is even more "wonderful". The car has three power combinations, namely 86 horsepower 1.4 liters, 102 horsepower 1.6 liters and 124 horsepower 1.8 liters in-line four-cylinder engines. From 1984 to 2009, it was officially discontinued. After repeated "face-lifting" production, although the interior design of Volkswagen Citi keeps pace with the times, its appearance will always maintain the original essence of the first generation of golf, and the Rabbit pickup truck model in North America market was named Caddy for production in South Africa. During the 25-year production cycle, a total of 377,484 Volkswagen Citi rolled off the production line. In Mexico, the first generation of golf was named Caribe for sale. From its birth in 1974 to its discontinuation in 1983 (Citi didn’t discontinue production until 2009), the first generation of golf sold a total of 6,780,050 sets worldwide. Such impressive sales laid a solid foundation for its future development, and the new "national car" also gained a firm foothold.
