Today, Huawei will hold the largest global developer conference in history. The HarmonyOS operating system developed by Huawei itself has become the most noticeable hot spot of this conference. Previously, Huawei registered the trademark of HarmonyOS operating system, which attracted worldwide attention. Ren Zhengfei, chairman of Huawei, said that the HarmonyOS system was not specially used for mobile phones. But for the internet of things. HarmonyOS system can control the time delay to 5 milliseconds or even milliseconds or sub-milliseconds. This operating system can be compatible with such things as autonomous driving, industrial automation, printed circuit boards, switches, smart phones and data centers.

In the 5G era, the ecological war of HarmonyOS system.

The HarmonyOS system does exist. And it is very powerful. Ren Zhengfei also admitted that HarmonyOS’s shortcoming is that its ecological environment is not as good as that of Android. Huawei’s mobile phones have a large share of overseas sales. But Google’s Android system is the mainstream in overseas markets, and it will take time for HarmonyOS to replace it overseas. But from Ren Zhengfei’s words, we can analyze that although HarmonyOS system is not specially used for mobile phones, it does not mean that it cannot be used for mobile phones.

Huawei Developers Conference

Since the registration of HarmonyOS operating system, there has been a saying that it is a branch of Android system. This is a misunderstanding. Dr Zhang Rujing, the founder of SMIC, analyzed that HarmonyOS was not a branch or modification of Android. It is a brand-new and independent operating system. It is developed for the future 5G Internet of Things.

Google also has a Fuchsia system for the 5G Internet of Things. However, the optimized version of HarmonyOS’s Ark compiler based on EMUI version 9.1 is much faster than the Android native compiler in performance. Then, Google’s Fuchsia and Huawei’s HarmonyOS system are at the same level, while the Android operating system is at a lower level.

Whether Google’s Fuchsia or Huawei’s HarmonyOS system, their ultimate goal is to replace the 4G Android system. At present, the development progress of HarmonyOS system far exceeds that of Google’s Fuchsia system. And HarmonyOS system will definitely be released before Fuchsia.

Ark compiler+HarmonyOS system, let Android experience surpass Apple.

Smartphones are a very important aspect of Huawei’s 5G business. So how can Huawei’s smartphones establish their own ecological environment as soon as possible? This problem should be discussed in two aspects.

First of all, utilitarianism: This is the most fundamental condition and opportunity for HarmonyOS system to quickly open its own ecological environment. The code of APP is not machine code but byte code. If someone develops a system, as long as the virtual machine and compilation module are compatible with the bytecode of Android APP, then the system can directly use the Android APP ecosystem.

Secondly, it is openness: Huawei opens its own Ark compiler. Let more technicians who support Huawei participate.

In this way, I believe that Huawei’s ecological environment will be established soon. Yu Chengdong announced at the Weibo that the open source Ark compiler would be released at the Huawei Global Developers Conference on August 9th.

Huawei Developers Conference

Android system is written in Java language, which is easy to learn. But it has a disadvantage, that is, it can’t communicate directly with the bottom of the system. Can only run on so-called virtual machines. To put it bluntly, the virtual machine is equivalent to a setter. First, the Android application is installed on the virtual machine, and then it is passed to the bottom of the machine.

Then the problem comes. What if the setter has a problem? The performance in Android system is the mobile phone software Caton. So, can you communicate directly with the bottom of the machine without this setter? Ark compiler solves this problem. All software of Android system can communicate directly with the bottom of the system through the compilation of Ark compiler.

Then HarmonyOS system plus Ark compiler will replace the setter of virtual machine. Why doesn’t Apple’s mobile phone get stuck in use? It just doesn’t have the setter and writes code directly for the bottom of the machine. The software of Apple’s mobile phone runs much smoother than that of Android.

Another issue worthy of attention is that Huawei’s HarmonyOS system is a microkernel. In fact, the kernel of the operating system can be a macro kernel or a micro kernel. The system development of macro kernel is difficult, and many functions with extremely high authority can be realized in it. After all, most of the functions of the operating system are in it, and solving the problem is the most direct. The Android system belongs to the macro kernel.

Because these modules have the highest authority, as long as one module goes wrong, the whole system will collapse. Microkernel, on the other hand, has few modules with the highest authority, such as task management of operating system and memory allocation and recycling management. Other modules do not have the highest authority, so even if there is an error, the system will not crash. Similarly, the development of microkernel is difficult, but the system stability is high.

At present, Huawei has officially announced the installation details and download address of the Ark compiler in the official community. In the near future, Huawei may also build an ecosystem like Apple, Microsoft and Google. (The author is a researcher at the Institute of Philosophy, China Academy of Social Sciences)

　　As the basic work of accurate poverty alleviation, the accuracy of poverty alleviation information is very important. Guizhou fully relies on big data and cloud computing to innovate poverty alleviation and development means, and explores a new poverty alleviation model of "internet plus" by building a "poverty alleviation cloud" platform in the province. "Poverty Alleviation Cloud" aims at different reasons and different types of poor people, and provides the right medicine, precise poverty alleviation and precise poverty alleviation. For regional poor people, it vigorously implements the ecological transfer project for poverty alleviation, fundamentally helps solve livelihood problems, and enhances the endogenous motivation for the development of poor areas and poor people.

　　Transparency of poverty alleviation information

　　In the flower base of Yangliu Community, Xiehe Town, qianxi county City, Guizhou Province, more than 150 mu of Gerbera jamesonii blooms brilliantly, and 61-year-old Zhou Xuefen is bending over and picking one by one. "More than 10 mu of Gerbera jamesonii is transferred to the base with guaranteed dividends, and there is still 1,200 yuan for work every month. My wife and I have 2,400 yuan, and we saved more than 20,000 yuan last year."

　　Zhou Xuefen’s family was identified as a poor household in 2014. The old couple were unable to serve these ten acres of land. In addition, his wife Wang Kaifu was sick before, and he owed more than 10,000 yuan in debt just for seeing a doctor. Last year, the poverty alleviation cloud management platform was built in the province. The system shows that through the evaluation of housing, labor and other indicators, the causes of poverty in his family are disease and lack of development funds.

　　At the beginning of 2015, the village introduced enterprises to engage in flower planting, and the Zhou Xuefen family was first included. With industrial coverage, the hand is getting richer. At the end of the year, Zhou Xuefen’s family took off the hat of poor households. However, the information of Zhou Xuefen’s family can still be found on the "Poverty Alleviation Cloud" system led by Guizhou Poverty Alleviation Office. The system shows that his family scored 69 points through various indicators evaluation, which has reached the poverty alleviation standard.

　　"A temporary increase in income does not mean that poor households can completely say goodbye to poverty, help the horse to send a ride, and keep abreast of their industries, diseases, education and other conditions through systematic dynamic monitoring to prevent them from returning to poverty due to accidental factors." Zhou Xing, chief agronomist of Guizhou Poverty Alleviation Office, said.

　　Not only Zhou Xuefen, but also the information of 6.23 million poor people in Guizhou province (statistics as of the end of 2014, including more than 1.2 million people who have been lifted out of poverty) is clearly displayed on the "Poverty Alleviation Cloud" system. Click on the system, from the poverty situation in the whole province to the topography, industrial distribution of a village, and even the housing, population and income of a poor household, with pictures and texts, it is clear at a glance.

　　Relying on big data and cloud computing, in December 2015, the "Poverty Alleviation Cloud" was launched, realizing the precise management, dynamic management and scientific management of big data for poverty alleviation and development in Guizhou, and the poverty alleviation information was open and transparent.

　　A display screen, a map of Guizhou, and jumping data show the information of migrant workers, poverty status and causes of poverty in the region in real time … … Guizhou put the breakthrough point of accurate poverty alleviation on accurate identification, found out the number and situation of poor people, and set up a file on the "poverty alleviation cloud" management system to realize the quantification of poverty identification and the visualization of poverty level.

　　According to the real-time display of the system, as of June 17th, there were still about 4.93 million poor people in Guizhou, and the incidence of poverty was 14.37%. The per capita disposable income of poor farmers was 6681.68 yuan, with 66 poverty-stricken counties, 928 poverty-stricken towns and 9000 poverty-stricken villages.

　　Visualization of poverty assessment

　　"To carry out poverty alleviation work, we must first identify the poor, and identifying the poor through big data is the first step of accurate identification." Zhou Xing said that the biggest feature of the "poverty alleviation cloud" is to collect information on poor households through household visits and surveys, and form a scientific and reasonable poverty assessment system based on the "four views".

　　According to reports, this four-view evaluation system — — Looking at the house, the grain, the labor force and the reader, a total of more than 80 indicators, showing the situation of provinces, cities, counties, towns and villages in the form of pie charts. Among them, the pie chart composition of housing includes: per capita housing is more than 30 square meters, 10-mdash; 30 square meters and less than 10 square meters; The pie chart composition of grain includes: more than 2 mu of cultivated land, 1-mdash; 2 mu, less than 1 mu, no arable land; The composition of the pie chart of the labor force includes: the labor force accounts for more than 50%, 40% and less than 20% of the family population, and there is no labor force; The pie chart of Reading Lang includes: no education debt, less than 5,000 yuan, 5000— 10000 yuan, more than 10000 yuan. Show the poverty score and distribution of poor people (households) through four views, and what kind of assistance measures are taken to further position the poor people.

　　Zhou Xing said that the "Poverty Alleviation Cloud" integrates various indicators through big data to form a poverty alleviation index, and those below 60 points are real poor households, 60-mdash; 80 points are poor households who reach the poverty alleviation standard but are easy to return to poverty, and more than 80 points are poor households who are stable out of poverty, which is used as a standard to assist in identifying poor households. "In the past, the exit of poor households was only a simple investigation of their income, housing and whether they had dropped out of school, mainly based on qualitative analysis. Now it is more scientific and reasonable to visualize all indicators through the system."

　　In addition, through the "Poverty Alleviation Cloud", we can supervise the responsibility chain, task chain and project capital chain in real time, do a good job in the implementation of each link, and achieve accurate poverty alleviation.

　　At present, there are about 5 billion yuan of project funds in Guizhou every year, and there are 10 thousand to 15 thousand projects in the village. How to ensure these projects are implemented is a difficult problem. Zhaowei, development manager of Inspur Group, the technology developer of "Poverty Alleviation Cloud", said that "Poverty Alleviation Cloud" is based on GIS (Geographic Information System) and takes mobile terminals as the carrier to build a mobile inspection system for poverty alleviation work focusing on establishing poverty-stricken households and project funds. "The electronic map of poverty alleviation cloud vector model has been expanded to 16 floors, reaching a scale of 1: 5000, and the positioning of poor households and poverty alleviation projects has been accurate to the village level, realizing random inspection and poverty alleviation projects at any time.

　　Dynamic assistance measures

　　Through the data extraction and analysis, the "Poverty Alleviation Cloud" can also show the poverty-causing reasons of the poor, including: illness, disability, school, disaster, lack of land, water, technology, labor, capital, backward traffic conditions, lack of self-development motivation, etc. Through the analysis of the poverty-causing reasons, it can help to formulate accurate poverty alleviation measures.

　　Systematic data show that the top three causes of poverty are lack of funds, lack of skills and poverty caused by learning, accounting for 30.0%, 17.2% and 14.7% respectively.

　　Zhaowei said that the "Poverty Alleviation Cloud" aims to expand information collection channels, improve data processing capacity and efficiency, deeply tap the value of data, provide real, reliable, timely and comprehensive decision-making data for poverty alleviation, and escort the final realization of precise poverty alleviation and precise poverty alleviation.

　　The purpose of accurate identification is to accurately help out of poverty.

　　"Through big data technology, after mastering the information of the poor population and the causes of poverty, we will monitor the implementation of pairing, assistance plans, implementation of assistance plans and assistance measures for provinces, cities, counties, towns and villages, respectively, identify the distribution of the poor population that has been implemented and not implemented, and display relevant information such as people or units that have been assisted. Through the analysis of the assistance situation, we can clearly understand the actual assistance of the poor people in provinces, cities, counties, towns and villages and assist in the implementation of the assistance task. " Zhou Xing said.

　　Liu Yuankun, vice governor of Guizhou Province, said that using big data to implement precise poverty alleviation and building a "poverty alleviation cloud" can really make the target precise, make the reasons clear, standardize the management, and make policies according to households and people. The system shows that 1,554,196 poor households and 4,888,885 poor people in Guizhou have all been included in the assistance plan, achieving the right medicine, precise drip irrigation and targeted treatment.

In the automobile industry, the engine is known as the "heart" of the automobile, and its quality directly determines the performance and reliability of the vehicle. Among many automobile brands, four brands have excellent engine quality, and the failure rate is almost zero, which has become the first choice for consumers to buy cars.

First place: Honda. Honda is famous for its excellent engine technology, and its i-VTEC technology not only provides excellent power performance, but also ensures fuel economy. Honda engine is famous for its durability and low failure rate. Many owners of Honda models say that the engine can still maintain excellent running state even after years of use.

Second place: Toyota. As one of the largest automobile manufacturers in the world, Toyota’s engine technology can’t be underestimated. Toyota engine is famous for its high efficiency, stability and low failure rate. Its Dynamic Force Engine series engines not only provide strong power, but also perform well in fuel economy and environmental protection.

Third place: BMW. As a luxury car brand, BMW’s engine technology is also leading, and BMW’s engine is famous for its excellent power performance, efficient fuel economy and superb technology level. Its N series and B series engines not only provide strong power for BMW models, but also win wide praise from consumers for their high reliability.

Fourth place: Mercedes-Benz. As a representative of luxury cars, Mercedes-Benz’s engine technology has also reached the top level in the industry. Its M-series engine is famous for its high efficiency and low failure rate, which provides excellent driving experience for Mercedes-Benz models. Many owners of Mercedes-Benz models say that the engine can still maintain excellent performance even after long-term use.

The reason why these four brands of engines can reach such a high quality level is their continuous investment in technology research and development and strict control of product quality. They not only innovate in engine technology, but also make great efforts in material selection, production technology and quality control to ensure that each engine can meet the highest standards.

For those consumers who are preparing to buy a car, it is undoubtedly a wise choice to choose these brands. Their engines can not only provide excellent performance and fuel economy, but also ensure stability and reliability in long-term use, bringing consumers a more secure and enjoyable driving experience.

Wen | wardrobe

Historically, there are countless long-lived models. However, if any car is still active in the car world over the age of 60, I can only tell the S-class harmony at one time, even though the facade of the 3 Series is "only" 44 years old.

60 years old is a hurdle in life, so it is true for cars. Most of the models that can prolong life so far occupy the position of "king" of the brand family and are the undisputed masters.

But it gives a different answer, because the handle is a taxi.

Old car fans should know that its predecessor is called "BULEBIRD", which is different from the new LANNIA derived later. It is the true "native bird" that expresses one’s heart directly.

It came out in early 1959, when it was also called Datsun. The most epoch-making place of the first generation is that it was not only sold in Japan, but also exported to South Korea. It can also be seen in Taiwan Province, China, but its name was changed to Yulong 704. At the same time, it is also very popular in Europe, and it is the first Japanese car with a hot sales in Europe.

At that time, Japan had already sent MacArthur away, and gradually emerged from the ruins after World War II, and the economy entered a period of rapid recovery. However, the industrial level still lagged behind the western European world, and cases of successful East learning emerged one after another. At the same time, the early generation, which had high hopes, entered the American market and failed, and the oil crisis that made Japanese cars rise in an all-round way didn’t happen until the 1970s.

Therefore, the success of the first generation in the western market was a feat of the Japanese community. Since then, it has established its status as a best-selling car and a pillar.

Aside from the sporadic imports into the coastal areas of China in the 1980s and 1990s, the real origin with the China market began in the Millennium.

In 2000, the first car was officially rolled off the production line in Huadu Factory, which was built on the basis of the ninth generation U13 laid in the 1990s. When everyone thought it was the first brand to make cars bigger for consumers in China, the first generation knew how to comply with consumers’ requirements, and extended the length from 4585mm to 4664mm (but it remained unchanged at 2620mm). At the same time, it modified the configuration according to local conditions and was set to be more in line with the complex road conditions in China.

In 2001, the acquisition and reorganization were completed, and the technology imported from Japan was upgraded and improved, and the second and third generation domestic products were introduced one after another. The second generation was produced in Xiangfan, Hubei Province, and the car was equipped with a car phone and a HUD flat display, which seemed to be against the sky at that time, making the competitor Santana 2000 look like a hick in front of it.

In 2003, the third generation was produced, which changed little compared with the second generation, mainly reflected in the two-color and pie. It is worth remembering that this generation was the last cooperation with Taiwan Province Yulong. After that, a joint venture company was established, which we are familiar with now.

In 2004, Zhizun was introduced, and the service for the carriage environment was brought into full play in this generation. Not to mention satellite navigation and Bluetooth phone, even the seats have pneumatic massage function. The fame of the big sofa may have been established from this time.

From to, the cumulative sales volume in China exceeded 300,000 vehicles, which kept the top three sales volume of mid-level vehicles at that time, and made great achievements for its development. The model was renamed after Zhizun, and perhaps even I didn’t expect it. The 300,000 was originally only one tenth of the later army.

Last night, the 14th generation was officially listed. Although the design has been striving to be younger in recent years, the whole listing conference revealed a strong family from slogan, scenery, cut-out animation, short story, every word of the leader’s speech, the host was a couple file composed of david lee and Guo Xiaomin, and even "Kiss My Baby" sung live by Emil Wakin Chau.

The bottom of my heart is very clear, young is young, and the root of living is never to be lost.

The essence of Zhenge is to serve the family, and the things that serve the family often have just-needed properties. Therefore, the 14th generation powertrain is composed of the 3rd generation HR16 1.6L naturally aspirated CVT, and the taste is still familiar.

Thanks to the drop to 0.26Cd, which is comparable to the level of GT-R, the 100 km is further squeezed from 5.2L in the previous generation to only 4.9L in the new generation.

What bike do you want?

In addition to being close to the people, there is also the price. The guide price of the new car is 109,000-143,000 yuan, which is lower than the guide price of 119,000-149,300 yuan sold in the later period of the previous generation. If there are no accidents, the thirteenth generation models will be classified as classics and sold together with the new generation and two generations.

According to the data of the Ride Association, it won the first place in China’s sales list with 481,216 vehicles last year, which is largely related to its strategy of "new and old under one roof".

Generally speaking, explosive cars have the following portraits: large market demand, appropriate timing, high value, niche but accurate positioning, perfect channel sinking work and price advantage. Only one car needs to meet the characteristics in the above portraits, and it doesn’t need to meet all of them. Sometimes it only needs to meet one, so it has the potential to become an explosive car.

More conservatively, demand and price are two explosion characteristics that must be met. When the new generation goes on the market, the old generation retreats to the second line and sells under the same roof. For car companies, the old model can not only reduce the production cost as much as possible, but also enlarge the price advantage of the explosion car twice.

Moreover, the sales data of the automobile market after entering the cold winter tells us that when the economic environment is facing downward pressure, consumers tend to choose models with high reliability and high value preservation rate, which makes it meet one more explosion factor of "the right time to appear".

When a car is a department, there are two cars, which meet the characteristics of three explosions. It is difficult to think about not selling much and not living long.

Therefore, when many car companies are busy completely rejuvenating their products, I think that moderate rejuvenation is a more rational decision. Because it is clear that what the "king of family cars" has to do is to interpret happiness as simple as that, and the simple definition of happiness is a family of four, with cats and dogs.

Slogan’s "people, cars, life" is the same.

　　The State Council joint prevention and control mechanism held a press conference on the afternoon of April 19th, introducing the situation of strictly grasping the epidemic prevention and control work, and paying attention together!

　　About the epidemic situation

　　The national epidemic situation is gradually stabilizing, but the cross-input between regions has obvious influence.

　　From March 1st to April 18th, 31 provinces (autonomous regions and municipalities directly under the Central Government) and Xinjiang Production and Construction Corps reported the local infected persons.497,214 cases, affecting all provinces except Xizang Autonomous Region.

　　Recently,The national epidemic situation has gradually stabilized.,However, the influence of cross-input between regions is obviousThe task of dynamically clearing all localities is very arduous.

　　Hebei, Jiangsu, Zhejiang, Anhui, Guangdong, Fujian, LiaoningThe epidemic situation in other provinces has generally stabilized.

　　Jilin City, Jilin ProvinceThe epidemic situation continues to improve and is in a downward trend.Changchun cityThe epidemic situation showed a downward trend. Recently, all newly infected people were found in centralized isolation. However, due to the large infection base, community risks have not been completely eliminated. It is necessary to continuously strengthen epidemic prevention and control measures and consolidate prevention and control achievements.

　　ShanghaiRecently, the epidemic situation is still at a high level, the risk of community communication is still high, the situation of prevention and control is still grim, and the task of prevention and control is still very arduous and urgent.

　　There is essential difference between dynamic zero clearing and zero infection, and dynamic zero clearing is the best choice of prevention and control strategy in China.

　　There is an essential difference between dynamic zero clearing and zero infection. Dynamic zero clearing means that for the COVID-19 epidemic,Discover and destroy together.To prevent Covid-19 from spreading in the epidemic area and prevent the virus from spreading to other areas.Dynamic clearing does not pursue zero infectionHowever, in order to eliminate an epidemic, it is required to stop the spread in time at the place where the epidemic occurred, and no new infection occurred. In other words, the whole country is not required to be free of COVID-19 infection at a certain time, but for every outbreak,It is required to control it in a short time..

　　After a person is infected with Covid-19, after 1-2 days of virus replication and growth, detoxification occurs (i.e., nucleic acid test is positive), and detoxification continues for about 7-12 days. Covid-19 can only survive if it keeps spreading from person to person. If the infected person cannot spread the virus to others after the longest detoxification time, the virus will be destroyed by the human immune function.Find out all the infected people in an epidemic, take physical isolation to stop their spread, and keep a longest detoxification time from infecting others, and the virus will be eliminated at the epidemic site.Therefore, the earlier the epidemic is discovered, the smaller the epidemic scale, and the easier it is to achieve dynamic clearing.

　　In the case that there is no local continuous spread of COVID-19 epidemic and the local COVID-19 epidemic is mainly imported from abroad, the dynamic zero clearing strategy is the best choice. After the Battle of Hubei and the Battle of Wuhan, the local spread of COVID-19 epidemic in China was mainly caused by foreign imports. Over the past two years, the prevention and control practice has proved that we can find and eliminate the imported aggregated COVID-19 epidemic together. "Dynamic zero clearing" is to get the maximum social effect with the minimum social cost, which is in line with the actual prevention and control in China.It is the best choice for China’s prevention and control strategy..

　　Covid-19 is likely to develop in the direction of increasing infectivity and weakening pathogenicity, and it is also likely to develop in the direction of increasing infectivity and pathogenicity.

　　Some people think that Covid-19 is mutating towards increasing infectivity and weakening pathogenicity. In fact, from a biological point of view,There is no essential connection between infectivity and pathogenicity.. The reverse relationship between these two aspects is more determined by people’s sociological attributes. When the pathogenicity is weakened, the symptoms of infected people are mild, and they have more time to be socially active and contact more people, resulting in more people being infected. At present, there is no obvious regularity of Covid-19 variation in infectivity and pathogenicity.It is possible to develop in the direction of increasing infectivity and weakening pathogenicity,It is also possible to develop in the direction of increasing infectivity and pathogenicity.. In the face of the ever-changing Covid-19, for ordinary people, it isDo a good job of vaccination,Adhere to the implementation of personal protective measuresSuch as wearing a mask, paying attention to hand hygiene, keeping social distance, etc.

　　About freight logistics

　　Accelerate the promotion and use of the national unified and mutual recognition pass.

　　As of April 17th, 23 provinces across the country have established the pass system as required, 31 emergency materials transfer stations in 10 provinces have been put into use one after another, and the Shanghai Port Card Pass has been implemented steadily, and the transportation guarantee of key materials has been improved obviously.

　　Start-up procedure of pass:

　　Normal areas do not need passes according to regulations.In areas with epidemic situation, the provincial joint prevention and control mechanism at the middle and high risk location will decide whether to activate the pass system according to the situation of epidemic prevention and control in this area and the demand of transportation of key materials. At the same time, the provinces that have issued passports in the early stage should speed up the transition with the national unified style passports and do a good job of convergence.

　　Scope of use of the pass:

　　passportMainly concentrated in medical and prevention materials, daily necessities, government reserve materials, postal express and other livelihood materials, as well as some important production materials such as agriculture, energy, raw materials and key industrial products.. Of course, the provinces that start the pass can also appropriately expand the scope of use of the pass according to the actual needs of the upstream and downstream of the industrial chain supply chain within their jurisdiction.

　　Pass distribution channels:

　　The provincial joint defense and control mechanism that has enabled the pass system will be supervised according to the unified national format.The receiving and delivery unit in the area where the pass is enabled will apply to the local departments of development and reform, industry and information, public security, transportation, commerce, agriculture and rural areas for free.. These departments will issue them separately according to the needs of the receiving and delivery units such as the supplier, material demanders and transportation enterprises, and according to the principles of priority, timeliness, safety and convenience.

　　The process of using the pass:

　　Pass is used according to "one car, one card and one line". People, cars, cards and lines must be consistent with the information indicated in the pass and can be reused within the validity period. Paper and electronic passes have the same effect.At present, the Ministry of Transport is relying on information technology to promote the online processing of passes and the online and offline multi-channel distribution. For vehicles with passes and meeting epidemic prevention requirements, special passages should be set up in areas where conditions permit to ensure the rapid passage of vehicles.What needs special explanation is that there is no need to apply for a pass if there is no pass system at the place of origin and destination of transportation.

　　In the process of using the pass, because the grass-roots law enforcement officers may not understand the policy and the information sharing is not timely, vehicles may encounter such problems in the process of passing. In this regard, the Ministry of Transport will also announce the relevant telephone numbers, and at the same time disclose the relevant information about issuing certificates to the public, dispatch the traffic situation, strengthen dynamic monitoring, and urge the relevant local departments to coordinate and deal with it in time to ensure the better implementation of this system and make everyone walk more smoothly.

　　Truck driver’s "Take, Go and Chase"+"Closed-loop Personnel Management"

　　firstNucleic acid test results are universally recognized by the whole country, and repeated tests are not required within the validity period.

　　secondFor truck drivers with negative nucleic acid test certificate within 48 hours, green health code and normal body temperature test, all localities should directly release them, and it is not allowed to "layer by layer" to restrict traffic.

　　thirdIf the result of nucleic acid test exceeds 48 hours at the destination, the method of "nucleic acid test+antigen test" can be adopted. If the result of antigen test is negative, it should also be released immediately, and the passage should not be restricted on the grounds of waiting for the result of nucleic acid test. At the same time, a dynamic tracking mechanism is implemented, and once the nucleic acid test result is positive, it will immediately notify the front to implement control measures.

　　fourthEstablish and improve the information sharing mechanism of truck drivers, and implement "white list" management. For truck drivers who walk through the cities where high-risk areas are located, or stay for no more than 4 hours, they are not allowed to be coded with "stars".

　　The 12328 traffic and transportation service supervision hotline is on duty 24 hours a day.

　　Smooth the working channels of "handling complaints immediately and coordinating individual cases", give full play to the role of the 12328 traffic and transportation service supervision hotline, and adopt 24-hour duty.For the problems reflected by the masses,First time tracking, first time coordinated solution. The local authorities promptly accepted the relevant issues such as the passage of port waterways and the poor passage of port collection and distribution vehicles.

　　Mail express sent to low-risk areas shall not be refused without reason.

　　Take postal express as the transportation guarantee scope of key livelihood materials; In areas with serious epidemic situation, distribution sites will be set up by relying on facilities such as express delivery parks.Taking postal express as the focus of people’s livelihood,Effectively guarantee the passage of postal express vehicles; For trunk line transport drivers and couriers who encounter sudden, temporary and urgent basic living difficulties, timely measures should be taken.Help tide over the difficulties.

　　Urge postal enterprises and express delivery enterprises to strengthen the analysis of the situation of the whole network affected by the epidemic,Optimize and adjust the network transportation and routing during the epidemic.. Require enterprises to express mail sent to low-risk areas.Shall not refuse to collect without reason..

　　We will strive for more support from relevant units in the orderly resumption of operation of the distribution center, allowing couriers to enter the community, and adding contactless delivery facilities, and strive to provide free nucleic acid testing or antigen testing for couriers, temporary accommodation in sealed control areas and other assistance policies.Support couriers to return to their posts with peace of mind.

　　About spring ploughing production

　　How to implement differentiated prevention and control measures to ensure that spring ploughing production is not missed?

　　In principle, the villages (villages) shall be used as the units to divide the areas for blockade control, control and prevention, and the precise prevention and control shall be implemented by classification, so as to prevent "one size fits all", "simplification" and "layer by layer overweight".It is strictly forbidden to set up checkpoints to intercept or open roads and seal villages at will..

　　In counties (cities, districts) where no epidemic has occurred, the requirements for normalized prevention and control shall be implemented.Ensure the normal development of agricultural production.

　　County (city, district) where the epidemic occurredGuard areaOn the basis of implementing the control measures,Ensure the normal flow of agricultural materials, agricultural machinery, agricultural products and farmers., orderly carry out farming activities.

　　County (city, district) where the epidemic occurredControl areaOn the basis of taking measures such as nucleic acid detection and closed-loop management, reasonably arrange agricultural production,Farmers are allowed to work "two points and one line" at different times and peaks, from home to farmland and from farmland to home..

　　County (city, district) where the epidemic occurredSealed control area, to organize farmers to do a good job.Help farming and planting., relying on social service subjects to carry out custody services to help farmers who can’t leave the village to plant enough seeds and plant them in the appropriate sowing period.Ensure that farming time is not delayed and farmland is not abandoned.. At the same time, under the premise of personal protection, agricultural technicians should be allowed to carry out guidance services in the fields.

　　Make every effort to unblock the transportation channel of spring ploughing agricultural materials, and give priority to issuing passes, giving priority to transportation and giving priority to release.

　　In areas where there is no epidemic,Do not arbitrarily restrict agricultural machinery transportation and field work.. In areas where the epidemic has occurred, it is necessary to take villages (villages) as units to organize and find out the demand for spring ploughing machines, spare parts and farm workers, and connect the service subjects, suitable machines and operators one by one.Shall not restrict qualified agricultural machinery to work in the field..

　　At the same time, it is necessary to fully unblock the transportation channels for spring ploughing agricultural materials, include agricultural materials such as fertilizers, pesticides and seeds and their production raw materials, agricultural machinery and spare parts into the transportation guarantee scope of key materials, and implement the green channel policy of ensuring supply.Give priority to issuing passes, shipping, loading and unloading, inspection and release..

　　The Ministry of Agriculture and Rural Affairs opened a number of hotlines and online message platforms, such as spring ploughing, agricultural materials guarantee and supply.

　　Affected by the recent sporadic epidemic situation in COVID-19 and the clustering epidemic situation in some areas, it has affected farmers’ going to the fields, agricultural materials, agricultural machinery and farmers going out to return home to farm. The Ministry of Agriculture and Rural Affairs has been paying close attention to these problems. In the early stage, it has issued a number of notices, such as grasping the production of spring ploughing and maintaining the normal production and marketing order of animal husbandry, and opened a number of hotlines and online message platforms, such as ensuring the supply of agricultural materials for spring ploughing, to solve the practical difficulties of farmers and market participants point-to-point.You can log on to the homepage of the website of the Ministry of Agriculture and Rural Affairs to view relevant information.,Reflect the difficulties and problems encountered by telephone or online message.The Ministry of Agriculture and Rural Affairs will check in time with relevant departments and localities to jointly promote the solution.

Whether it is the hot one or the upcoming one, without exception, it is divided into the subordinates, and many people regret that there is no model. Maybe these people have ignored their brands. After the introduction of this luxury medium-sized one, the market share occupied by this luxury medium-sized one is still unmatched by competitors. In fact, it seems that it has only been 10 years since its debut, but why did the first generation model sell for so long?

The first generation was launched in April 2008

The first generation made its debut in Los Angeles in November 2007, and then made its world debut in 2008. At that time, it was already full of confidence in the prospects of the Chinese market, and it was a representative of "official cars". It was on the A4 platform that a medium-sized one was developed. The appearance continued the design style of the third-generation Q7, and the exaggerated air intake grille showed the fashion and dynamic.

There are no bright spots in the interior design, but the configuration is equipped with high-end equipment such as adaptive cruise, three-zone automatic air conditioning, rear sunshade, MMI operating system, and/or ventilation. In terms of power, it is equipped with a 2.0T and 2.0T, two diesel, matching 6-speed manual and 7-speed. Among them, the 2.0T is the second-generation EA888, 211, and the peak torque is 350 Nm.

Although the first generation was claimed to be dynamic and all-round at the beginning of its launch, it was equipped with a quattro system and a sensitive driving mechanism. However, considering the affordability, the electronic equipment was quite helpless when it intervened, and it was not equipped with a wheel-to-wheel slip limit device, which greatly reduced the off-road performance.

In October 2009, the domestic price was introduced by import 577,000

On October 29, 2009, the Q5 was officially listed in the Chinese market, with a price range of 57.7-67 8,000, which disappointed some domestic consumers. The model only provides 2.0T and 3.2L two kinds of power, both matching 7-speed, and standard quattro system. At the press conference, the domestic pre-sale price range was also announced: 37-530,000 yuan, and the domestic Q5 became the only expectation.

In March 2010, the whole system of 2.0T + 7-speed dual-clutch combination was launched in China

After the first domestic launch in 2009, it was finally officially launched in March 2010. The price range is 37.98-53 9,800, which is slightly higher than the previous pre-sale price. As the first domestic medium-sized luxury, the shape and configuration are basically the same as the imported version. The power system only retains a 2.0T, which also matches the 7-speed. Because of the outstanding advantages in cost performance, it is logical to increase the price to lift the car.

November 2010 New Q5 Replacement 8AT

Less than a year after the new car was on the market, it couldn’t wait to launch a new model, replacing the original 7-speed with 8AT. Not only is the gear shift smoother, but without the concerns of dual clutch, the intervention of the electronic assistance system has become unscrupulous, and the off-road performance has been greatly improved. In other aspects, it is basically the same as the previous model, still equipped with the second-generation 2.0T EA888.

In April 2013, a mid-term facelift was carried out, and a new manual model was pushed down.

In 2013, the mid-term model was launched, which was mainly adjusted for details, and the shape of the front face, headlights and rear exhaust were changed. In addition to the new steering wheel, the configuration has also been improved, using the latest generation of MMI multimedia information interaction system. In terms of power, the domestic model launched a 2.0T low model, matching 6 speeds; the model was replaced with mechanical supercharging, and there was a 2.0T plug-in system model.

In December 2014, the whole series replaced the third-generation EA888

In 2014, the Q5 model was replaced with the third-generation EA888, which mainly added hybrid injection technology. The maximum output was increased from 211 to 224, and the peak torque remained unchanged. The new model still retains the low-end model, which is also matched with 6 speeds. In addition to the update of the power system, the high-end model can also be equipped with a "driving mode selection" system to achieve different driving feelings.

In September 2016, the second generation of the world premiered and returned

The new generation of the new model officially debuted in 2016. The front face is shaped like a scaled-down version of the Q7, with sharp and tough lines. The side and tail retain the general outline of the current Q5, and it still looks classic, which is a tribute to the previous generation. The new car is also built on the same MLB Evo platform as the previous model, which is expected to be greatly reduced.

The biggest change that the new can see is the interior design, which is enough to throw off the current model for several streets. At the same time, 12.3-inch full LCD instrument, electronic shift lever, wireless mobile phone charging, these high-end configurations are readily available. In terms of power, the new 2.0TFSI, 2.0TDI diesel and DI diesel are equipped with three models, matching 6-speed manual, 7-speed dual-clutch and 8-speed manual (DI diesel models only). In addition, in addition to the DI diesel model, which continues to match the quattro four-wheel drive system, the rest of the new models are a set of so-called quattro Ultra, which is actually the system.

2018 Quarter 1 Domestic listing lengthened

In order to meet the needs of domestic consumers, the new or the same as the A4 will be extended on the basis of the overseas version of the domestic model, and the new car will be launched to the domestic market in Quarter 1 in 2018. The domestic model will be the same as the current model, only a 2.0TFSI code-named third-generation EA888 will be retained, matching 7-speed. As for the four-wheel drive system, it will also be replaced by the latest quattro ultra system.

Editor’s summary: The current model is a car that is relatively balanced in all aspects, with rich configuration, abundant power, good handling performance, and most importantly, this car has no obvious shortcomings. This new generation of models uses a more advanced platform, and some high-tech configurations have also been devolved to Q5. For ordinary consumers, it has a greater temptation. But the absence of the quattro four-wheel drive system will somewhat affect consumers’ determination to buy it.
