I drive a Camry (parameter picture) twin engine, and there are three shortcomings that are unacceptable, and it is really expensive to change the battery. I advise people who want to buy a hybrid car to think twice, otherwise it will be too late to regret it!

The automobile industry is experiencing a great change that has never happened in a hundred years, and it has become an inevitable trend to develop new energy vehicles.

Plug-in hybrid vehicles and pure electric vehicles are the main models in the future, while hybrid electric vehicles will be eliminated in the future!

This is the real reason why Corolla twin-engine, Camry twin-engine, CR-V and other hybrid vehicles can’t be on the "green card"!

However, at present, Toyota and Honda-based hybrid electric vehicles have achieved high sales, and many consumers are waiting to see and want to buy a hybrid electric vehicle.

So is the current hybrid car worth buying? What are the shortcomings?

Next, I will analyze the advantages and disadvantages of the hybrid car and how much it costs to replace the battery, hoping to give some valuable information to readers who want to buy a hybrid car.

What’s the difference between Toyota THS, Honda i-MMD and BYD DM-i? Did DM-i learn from Honda i-MMD?

We want to know whether the hybrid car is worth buying. First, we need to understand the working principle of the hybrid car, so as to understand the advantages and disadvantages of the hybrid car!

At present, Toyota THS and Honda i-MMD hybrid systems are the main hybrid vehicles. Although both of them are hybrid systems, their working principles are obviously different.

The working principles of Honda i-MMD and BYD DM-i are more similar, so Honda CR-V has two hybrid models, one is a hybrid electric vehicle, and the other is a plug-in hybrid vehicle.

Honda’s i-MMD oil-electric hybrid uses clutches to realize three driving modes.

The first pure electric modeWhen the engine does not work, the clutch of the power separation device is disconnected, the vehicle is directly driven by the motor, and the power battery provides the power source. At this time, the working principle is the same as that of a pure electric vehicle.

The second hybrid modeThe vehicle is still directly driven by the driving motor, and the engine works normally. At this time, the power clutch is disconnected, and the engine is only responsible for driving the motor to generate electricity, and does not directly participate in the driving.

At this time, the working mode is more like an extended-range electric vehicle, and the driving principle is the same as that of an extended-range electric vehicle in Li ONE, so the engine always runs at the highest efficiency and the fuel economy is very high.

The third engine direct drive modeThe engine is working, the power clutch is closed, and the driver controls the power output of the engine through the throttle. At this time, the working mode is the same as that of the fuel vehicle.

When the vehicle needs to overtake and speed up, the motor intervenes to drive, and the auxiliary engine drives the vehicle together. At this time, the vehicle has the strongest power.

The above three driving modes are basically consistent with the working principle of BYD DM-i. Some people think that DM-I borrowed the working principle of i-MMD, but as early as 2008, BYD introduced F3DM, which is the world’s first mass-produced dual-mode vehicle.

The working principle of BYD F3DM is not the same as that of the familiar Tang DM, but the same as that of the Song Plus DM-I. As for why it was not accepted by the market at that time, the main reason was that the engine carried by the F3DM was too poor.

The DM engine is equipped with a 1.0L three-cylinder engine, and its power output is not strong. In the hybrid mode, the power output is insufficient, which makes it impossible to play the advantages of the hybrid mode, so it was eliminated by the market.

In 2012, Honda released the i-MMD hybrid technology, and in 2013, it officially launched the production model, so it was not DM-i that borrowed from i-MMD.

Toyota THS has developed into THS II, which is much better than the previous generation and can be divided into two driving modes.

The first pure electric modeThe engine does not participate in the work and will not start, and the vehicle is driven entirely by the motor, which is the first difference from Honda i-MMD.

However, the pure electric mode of Toyota THS II has a disadvantage, taking Camry twin engines as an example.

Because the battery is only 1.3kwh, it can only be turned on when the power is sufficient, and the pure electric mode can only travel about 2KM, and the speed cannot exceed 50km/h, otherwise it will directly exit the pure electric mode.

It can be said that the pure electric mode of Camry dual-engine is relatively small, but the application scenarios are still relatively rich. For example, the pure electric mode can be enabled when moving cars in short distances, congested roads and queuing, which can avoid the engine idling for a long time.

On the one hand, it can avoid carbon deposition caused by long idle speed of the engine, on the other hand, the engine stops working to achieve the purpose of saving fuel.

The second hybrid mode, due to the working principle of Toyota THS II, is divided into two working states in hybrid mode.

The first working stateDuring normal driving, when the Toyota THS II exits the pure electric mode, the vehicle directly enters the hybrid mode, and the engine and motor drive the vehicle at the same time.

When the power output by the engine is greater than the driving force required by the vehicle, the engine will drive the generator to charge the battery.

The second working stateWhen speeding up overtaking, long-distance climbing and high-speed driving, the engine and motor will still drive the vehicle together, but the engine will use all the power to drive the vehicle and the generator will stop charging the battery.

The power battery also uses all the electricity for motor-driven vehicles, at which time the vehicle has the strongest power. Because Toyota THS II has no engine direct drive mode, this is the second difference from Honda i-MMD.

The first disadvantage, the characteristics of the hybrid working mode of oil and electricity, can’t be green, can’t be exempted from purchase tax, and the price is expensive, saving fuel but not saving money.

Whether Toyota’s THS II or Honda’s i-MMD, the energy for driving vehicles in pure electric mode still comes from fuel.

The cruising range of pure electricity is too short, and the motor is only an auxiliary function. The main driving mode is the engine.

Therefore, hybrid electric vehicles are not new energy vehicles, so they can’t get a green license, and they can’t enjoy the same exemption from purchase tax as plug-in hybrid vehicles.

Take Camry twin engines as an example. The starting price is 219,800 yuan, 40,000 yuan more than the fuel version of the entry-level Camry, and 20,000 yuan more than the fuel version of the Camry with the same configuration.

Imagine that the hybrid of oil and electricity does save fuel, but can it save fuel and money?

I’ll work out an account for you.

With the same configuration, the fuel consumption of the fuel version Camry is 5.7L； per 100 kilometers; The average fuel consumption of Camry twin engines is 4.1L per 100 kilometers.

• The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.
• No.95 gasoline is 7.51 yuan per liter.

Camry dual engine saves 12.016 yuan in fuel per 100 kilometers compared with the fuel version of Camry. Driving 100 kilometers can save fuel in 12 yuan. Is it worth buying a hybrid car?

If the extra 20,000 yuan for purchasing the dual-engine version is used as fuel money,

20 thousand yuan can buy 95 # gasoline 150200L L.

The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.

Then Camry twin engines need to travel 93,875 kilometers to save the extra 20,000 yuan.

However, more than 90,000 kilometers, in addition to operating vehicles, basically few car owners can save fuel and money.

If a private car travels 10,000 kilometers a year, it will take at least 9 years to save money on fuel return, so it is said that hybrid electric vehicles save fuel but not money.

Moreover, it is not the same as plug-in hybrid cars. Although plug-in hybrid cars are also fuel-efficient and do not save money, they can get a green card without purchase tax, which is suitable for car owners.

Therefore, the first unacceptable disadvantage of the hybrid electric vehicle is that it saves fuel and does not save money. With the working principle similar to that of the plug-in hybrid vehicle, it can’t be a green card!

The second disadvantage is that the engine is noisy.

The engine noise of hybrid electric vehicle is very loud, which I felt on Camry twin engines, but it is not disturbing all the time, mainly in two cases, the engine noise will be very obvious.

In the first case, the cold car starts.

When the battery is fed, the cold car starts again. At this time, the engine noise of Camry dual-engine will be very loud, and the engine noise can be felt in the whole underground garage. Sometimes it will be caused by traffic jams for a long time, which may be because the engine water temperature is low.

When the car is cold, the engine can’t reach the best state, but it needs to drive the motor to charge the battery, which leads to the noise of the engine increasing under the combination of these two States.

In the second case, when driving at high speed, the battery is strongly charged.

When the Camry twin engines are driving on the highway, the engine cannot directly drive the vehicle due to the hybrid characteristics of Toyota THS II, so the battery must be charged.

Because the vehicle runs at high speed, it requires high power. At this time, it is necessary to drive both the vehicle and the motor to charge the battery, which leads to insufficient engine power.

In order to complete these two working conditions at the same time, the engine can only increase the speed, because the self-priming engine can only obtain the best power output at high speed.

Therefore, when driving at high speed and the battery is strongly charged, the noise of the engine will become very large. If it is sensitive to noise, it will affect the driving experience.

The third disadvantage is that the battery capacity is too small, and the power connection will shake.

As mentioned earlier, the battery capacity of the Camry twin-engine is only 1.3kwh, so it can only travel at a low speed of about 2km, which means that the Camry twin-engine basically travels in hybrid mode.

However, when switching from pure electricity to hybrid mode, sometimes there will be jitter, sometimes very small, sometimes very large, and sometimes not at all.

This is related to the small battery capacity. When the battery feed is switched to the hybrid mode, the engine needs to drive the vehicle and the engine to generate electricity at the same time, so the engine power is insufficient, and the power connection jitter appears.

If the power is switched when the battery is fully charged, and the engine and the battery drive the vehicle at the same time, there will be no jitter.

Therefore, the jitter caused by too small a battery may be unavoidable. This shortcoming is actually good, but it is somewhat unacceptable for car owners who pursue perfection.

Replacing the battery is expensive, so drive carefully.

Toyota and Honda’s hybrid electric system can be said to be very mature, and they all adopt "shallow charging and shallow discharging" to extend the battery life.

As long as the battery capacity of Toyota THS system is lower than 60%, it will stop discharging directly, while that of Honda is 55%.

This has both advantages and disadvantages. The advantage is that the battery can always be kept at more than 50%, which can increase the number of battery cycles and prolong the battery life.

The disadvantage is that the battery capacity of the hybrid electric vehicle is very small, and it is lightly charged and discharged every time, which makes it impossible to switch the power output mode for a long distance, which may cause the body to shake.

Due to the protection methods adopted by Toyota and Honda for the power battery, under normal use, the battery will basically not decay to the point where it cannot be used normally or be damaged.

Moreover, Toyota guarantees the battery for 8 years or 200,000 kilometers, and Honda guarantees the battery for 10 years or 200,000 kilometers, so the owner does not have to worry about battery damage, and it is expensive to replace the battery.

However, if the battery is damaged by the owner, it is not cheap to replace a battery.

Theoretically, taking the Camry dual engine as an example, the battery capacity is only 1.3kwh. At present, the power battery is 1,300 yuan /kwh, and it is 1,300 yuan to change a battery, plus the working hours are up to 3,000 yuan.

In fact, according to the maintenance cost of replacing the power battery exposed by the owner, it is obvious that it cost 23,848 yuan to replace the battery.

Therefore, it is not cheap to replace the battery in a hybrid electric vehicle, but as long as you drive normally, you basically don’t have to worry about the cost of replacing the battery.

Advantages of hybrid gasoline-electric vehicle

Although I mentioned the disadvantages of hybrid electric vehicles, its advantages cannot be ignored.

1. Whether driving at high speed or in traffic jam, the fuel consumption is relatively stable, and the fuel consumption per 100 kilometers is basically about 5L, which is very suitable for car owners who often run long distances.

2. A tank of oil can run more than 1000 kilometers, so you don’t have to worry about mileage anxiety, and you don’t have to refuel frequently. In today’s fast pace of life, the time saved is money.

3. No matter under any working conditions, the power of the hybrid electric vehicle can come at any time, the power output is better than that of the fuel vehicle, and the power ride comfort and driving experience are incomparable to that of the fuel vehicle.

The extra cost of buying a hybrid electric car may not be able to save fuel and money, but the driving experience is great!

Write it at the end

Hybrid cars are worth buying, but not for everyone.

If you don’t use cars frequently, don’t run at high speed, and just commute to work, then a fuel car is enough.

If there are requirements for power, endurance and long-distance driving, then a hybrid electric vehicle is worth buying.

If you buy a hybrid electric car just to save money, then I advise you to think twice. Actually, it doesn’t save money. If you buy it rashly, it’s too late to regret it!

　　BEIJING, Beijing, December 22 (Zheng Jiawei) "Programming education is not to cultivate code farmers, but to cultivate students’ programming ability, and the most important thing is the process, which trains the way of thinking in the process of presenting logical thinking and finally solves practical problems in life." Dr. Yu Xiaoya, a professor at Beijing Institute of Education, said.

　　On the 21st, an observation activity and seminar on innovative classroom teaching of programming education in primary and secondary schools was held in Beijing. On the day of the meeting, teachers from all over the country gathered in the No.1 Primary School of Exhibition Road, Xicheng District, Beijing to observe the programming demonstration class provided by the No.1 Primary School of Exhibition Road, and discuss how to further cultivate students’ innovative thinking and practical ability after the course.

　　In the demonstration class, under the guidance of the teacher, the students in Grade 5 of the primary school used the programming cat tool to complete the animation production and the programming of the voice-activated lighting system, respectively. Many students said that they liked the hands-on operation in class very much and wanted to continue to play programming when they got home.

　　Guan Jiying, one of the two teachers who participated in the demonstration class, was responsible for teaching the programming of acoustic control lighting system. After the students finished the basic programming of acoustic control system, she further inspired the students to think about the practical application of acoustic control system, and finally guided the students to program the noise indicator system. When the surrounding voices were normal, the green light turned on, but when the voice was too loud, it turned red.

　　On July 8th, this year, the State Council issued the Development Plan of the New Generation of Artificial Intelligence, specifically proposing to implement the national intelligence education project, set artificial intelligence related courses in primary and secondary schools, gradually promote programming education, and encourage social forces to participate in the development and promotion of educational programming teaching software and games.

　　Zhu Hui, a researcher in Xicheng District, Beijing, said in an interview with Zhongxin.com that although the State Council issued a notice to add programming to the classrooms of primary and secondary schools, schools still need to choose appropriate programming tools in the actual operation process to make this requirement a reality.

　　According to Zhu Hui, programming education in Xicheng District has always been in the forefront of Beijing. From the first computer elective course in 1982 to the graphical programming language education with "programming cats", it has always focused on cultivating students’ procedural thinking and solving problems in real life.

　　A few days ago, the National People’s Congress Standing Committee (NPCSC) voted to completely ban illegal wildlife trade, get rid of the bad habit of eating wild animals, and effectively protect people’s lives, health and safety.

　　This decision is obviously closely related to the COVID-19 epidemic. So, what is the relationship between Covid-19 transmission and wildlife?

　　Let’s sort out the recent related scientific research results.

　　On February 24th, a piece of news caught people’s attention. The National People’s Congress Standing Committee (NPCSC) voted to pass a decision on completely banning illegal wildlife trade, getting rid of the bad habit of eating wild animals, and effectively protecting people’s lives, health and safety. A system of completely prohibiting the consumption of wild animals has been established. In violation of the existing laws and regulations, the punishment should be aggravated on the basis of the existing laws.

　　At present, under the situation that the whole country is playing chess and fighting against the COVID-19 epidemic, this decision is obviously closely related to the COVID-19 epidemic.

　　Bats may be the source of Covid-19.

　　Humans are no strangers to infectious diseases caused by coronavirus. The SARS coronavirus, which was prevalent in winter of 2002 to 2003, was confirmed to have originated from the natural host bat, passed through the intermediate host civet cats and then passed on to humans. MERS coronavirus discovered in 2012, namely Middle East respiratory syndrome coronavirus, was also considered to have originated from natural host bats and spread to humans through intermediate host camels.

　　Since the winter of 2019, novel coronavirus, whose infection scale far exceeds that of SARS and MERS, has been transmitted to human beings through what channels?

　　Because of the lessons of SARS and MERS, scientists naturally set their sights on bats first.

　　Shi Zhengli’s team from Wuhan Institute of Virology, Chinese Academy of Sciences published a paper in the form of preprint on bioRxiv website on January 23rd, and this paper was published online by the top academic journal Nature on February 3rd. In this paper, the research team compared the novel coronavirus genome extracted from patients with severe pneumonia with the coronavirus gene sequence carried by a bat in the early laboratory, and found that the whole genome sequence of RaTG13 coronavirus in this bat was as consistent as 96.2% with novel coronavirus infected by human.

　　This means that the natural host of Wuhan novel coronavirus is probably a bat!

　　RaTG13, a virus closely related to bats, is the ancestral virus of novel coronavirus, which is derived from a coronavirus of China Jutoubat, which was discovered by Shi Zhengli’s team when sampling in Yunnan.

　　Moreover, novel coronavirus’s infection with humans needs to go through the pathway of ACE2 receptor. The similarity between the ACE2 receptor of China Jutous Bat and the human ACE2 receptor is consistent with the potential intermediate host other than other non-human primates. This shows that novel coronavirus, from bat virus to human infection, may not need an intermediate host, but can directly infect humans from bats.

　　In China, the hibernation period of bats is from December to late February. At first, people thought that the virus began to spread at the end of December last year, so the possibility of direct transmission from bats to people was ruled out. However, with more and more retrospective case studies, people found that novel coronavirus had been passed on to people as early as last November. Then, it is possible to pass it directly from bats to people.

　　For example, in a paper published on the website of ChinaXiv on February 21st, researchers from Xishuangbanna Tropical Botanical Garden of China Academy of Sciences, South China Agricultural University and Beijing Brain Center excavated the source and transmission path of Covid-19 from genome data. The researchers collected 93 genome data of novel coronavirus from 12 countries in 4 continents. According to the genome calculation, Covid-19 has undergone two large-scale expansions, one of which was on December 8, 2019.

　　It is inferred that the virus began to spread from person to person at least in early December 2019 or even in late November. Obviously, the virus should be transmitted from animals to people before human transmission. In other words, Covid-19 will be transmitted from animal hosts to humans no later than November 2019.

　　Pangolin may be the intermediate host of Covid-19.

　　At present, the academic circles still accept the conclusion that Covid-19 originated from bats and bats are its natural hosts, but there is no conclusion as to whether Covid-19 directly passed from bats to humans.

　　Many of the early cases of Covid-19 were related to the South China Seafood Market in Wuhan, Hubei Province, where there were a lot of wildlife transactions. China Center for Disease Control and Prevention also reported that Covid-19 was detected in environmental samples obtained from this market. More than 10 years ago, a similar wildlife market has been proved to be related to the SARS outbreak in 2002-2003, so wild animals probably participated in the spread of Covid-19.

　　At present, many scientists are looking for intermediate hosts in Covid-19, among which pangolin is the most likely candidate animal for intermediate hosts in Covid-19.

　　Among the papers speculating that pangolin is an intermediate host, two papers are most worthy of attention at present.

　　On February 18th, Professor Guan Yi from the School of Medicine of Hong Kong University and Hu Yanling from Guangxi Medical University published a paper on bioRxiv, a pre-printed website of medical papers, saying that genome sequencing showed that coronavirus was found in Malay pangolins smuggled from Southeast Asia intercepted in Guangdong and Guangxi, and the similarity with Covid-19 was between 85.5% and 92.4%. The paper holds that the coronavirus pedigrees found in pangolin are very similar to those in Covid-19, and pangolin should be regarded as a possible intermediate host in Covid-19, and it should be forbidden to be sold in fresh markets to prevent the spread of zoonotic diseases.

　　It was South China Agricultural University that first proposed that Malayan pangolin was an intermediate host. On February 7th, South China Agricultural University announced this research result: Pangolin is a potential intermediate host in novel coronavirus. Researchers from South China Agricultural University, such as Shen Yongyi and Xiao Lihua, joined hands with Yang Ruifu, a researcher from the Academy of Military Medicine, and Chen Wu, a senior veterinarian from the Scientific Research Department of Guangzhou Zoo to tackle the problem. By analyzing the virus genome, they found that the virus strain isolated from pangolin was 99% similar to the virus strain currently infecting people, and the receptor binding domains of the two viruses were similar.

　　In the preprint of the paper published later, they claimed that pangolin coronavirus was highly related to Covid-19. In particular, the receptor binding domain of pangolin coronavirus S protein is almost the same as that of novel coronavirus in 2019, with only one amino acid difference.

　　The paper also puts forward important serological evidence, that is, the coronavirus antibody in pangolin’s peripheral blood can bind to Covid-19. Moreover, pangolin infected by virus shows pathological changes and clinical symptoms similar to those of human beings.

　　In this paper, the author also boldly infers that the comparison of existing genomes shows that novel coronavirus in 2019 may have originated from the recombination of pangolin coronavirus and bat coronavirus RaTG13.

　　The paper also said that if the wildlife trade is not effectively controlled, the newly discovered coronavirus may pose a continuous threat to public health.

　　Wild animals are virus reservoirs.

　　What changes did novel coronavirus go through before it was brought into Wuhan and broke out in the crowd?

　　According to the evidence that scientists are looking for now, it may have originated from bats and spread directly to humans; It may also originate from the recombination of bat coronavirus and pangolin coronavirus, and then spread to humans through pangolin.

　　But to be sure, this is not the first or the last virus transmitted from animals to humans. In just 20 years of this century, there have been three kinds of new coronavirus epidemics: SARS, MERS and novel coronavirus.

　　In fact, it is not only the SARS virus and Covid-19 that have caused great losses to our country that are closely related to wildlife. Wild animals are the natural hosts of many serious emerging diseases. Statistics show that at present, 70% of new infectious diseases come from wild animals.

　　For example, natural reservoir, a bat that attracts much attention, has more than 100 kinds of viruses. They can carry many deadly viruses that are very dangerous to people, such as Ebola virus, Marburg virus, SARS virus, MERS coronavirus, Hendra virus and Nipah virus, but they don’t get sick themselves. This may be related to bat’s unique "all-weather" immune system.

　　"We all live on the virus planet, and wild animals are the reservoirs of these viruses." Nathan Wolf, Ph.D. in immunology and infectious diseases at Harvard University, once said this in "The Virus Attacks: How to Deal with the Outbreak of the Next Epidemic".

　　In our country, people have the backward concept of "eat what you eat to make up for what you eat", and there is also the mentality of eating novelty. All kinds of game are served on the table, and all kinds of wildlife trade are repeatedly banned. These invisible dangerous viruses will mutate in various trading links of wild animals and break through the species barrier — — From animal infectious diseases to human infectious diseases. With the increase of population density, the continuous progress of urbanization and the continuous improvement of the convenience of the national transportation network, once the relevant epidemic situation occurs, it will easily turn into a huge disaster and cause huge losses.

　　Although the relevant law enforcement agencies in China have made a series of achievements in prohibiting illegal hunting, breeding, transportation, trading and smuggling of wild animals, due to the lack of ideas and weak market supervision, there are still chaos such as openly selling wild animals and their products, and illegal hunting, transportation and trading of wild animals for the purpose of eating. However, the current Criminal Law and the Wildlife Protection Law lack or are insufficient in provisions on the consumption of wild animals, and the scope and intensity of sanctions are very limited.

　　We expect that, after the passage of the relevant bills banning the consumption of wild animals in an all-round way and severely cracking down on illegal wildlife trading, we will strengthen law enforcement in order to safeguard public health safety and ecological safety legally and in compliance, and prevent the recurrence of epidemics such as SARS and novel coronavirus.

　　Respecting nature, adapting to nature and protecting nature, and making "protecting wild animals and guarding against cross-species transmission of viruses" become the idea of each of us, which is the lesson we should learn from this novel coronavirus epidemic.

　　This year, the intended planting area of grain reached more than 1.78 billion mu, an increase over the previous year. Effectively deal with the freezing rain and snow and cold wave weather last winter and this spring, and strengthen technical guidance services. Winter wheat grows better than last year and all the year round, and the foundation for a bumper harvest of grain and oil production in summer is gradually laid down, and spring ploughing production is vigorously and orderly promoted. The supply of "vegetable basket" products is abundant, the production capacity of pigs is adjusted and optimized, the production of meat, eggs and milk is increased in an all-round way, and the supply of vegetables and fruits is stable.

　　Rural industries have a good momentum of development. In the first quarter, the added value of agricultural and sideline food processing industries above designated size increased by 3.3% year-on-year. Rural leisure tourism continues to heat up, and e-commerce of agricultural products grows rapidly. The per capita disposable income of rural residents reached 6,596 yuan, 2.4 percentage points higher than that of urban residents.

　　Rural construction and governance have been solidly promoted. By the end of March, the county-level rural construction project library had accumulated 614,000 projects and implemented project funds of 250.74 billion yuan.

　　Multi-measures to promote sustained recovery of consumption and promote high-level opening up.

　　At the press conference held by the State Council Information Office on April 19th, the relevant person in charge of the Ministry of Commerce said that in the first quarter, foreign trade made a steady start, emerging markets maintained vitality, and developed markets recovered. A survey of key foreign trade enterprises by the Ministry of Commerce shows that enterprises reflecting employment growth accounted for 1-mdash in March; In February, it rose by 1.7 percentage points to 88.8%, and the confidence expectation of enterprises was further enhanced.

　　Foreign investment maintained steady development. In the first quarter, non-financial foreign direct investment was 242.92 billion yuan, up by 12.5%, among which investment in ASEAN and EU grew rapidly, with growth rates of 36.7% and 34.5% respectively.

　　In the next step, the Ministry of Commerce will focus on promoting the continuous expansion of consumption, launch a series of activities around the theme of "Enjoy the benefits of the whole people throughout the year", focus on the cultivation and construction of international consumption center cities and the construction of modern business circulation system, and continue to introduce relevant policies and measures to continuously release consumption potential.

　　Link the world! The cumulative number of overseas buyers attending the Canton Fair has exceeded 120,000.

　　April 19th is the last day of the first phase of the 135th Canton Fair. During the five-day exhibition period, we felt the "attraction" of the Canton Fair, as well as the "centripetal force" of linking the world with new products and technologies.

　　As of April 18, the cumulative number of overseas buyers attending the meeting offline has exceeded 120,000, an increase of 22.7% over the same period of last year. They come from 212 countries and regions around the world. Not only the number of people has increased, but also the sources are all over the world. The top countries include India, the United States, Nigeria, Indonesia and Malaysia.

The quantity of spring ploughing agricultural materials is generally sufficient and the quality is guaranteed.

On April 19, the relevant person in charge of the Ministry of Agriculture and Rural Affairs said that the consumption of spring ploughing fertilizers, pesticides and seeds accounted for about half of the annual consumption. Judging from the current situation, the number of seeds, pesticides and fertilizers ploughed in spring this year is generally sufficient.

At present, the rate of fertilizer in place at the provincial and county levels has reached 95% and 90% respectively. The quality of agricultural materials is guaranteed and the prices are relatively stable. The prices of most varieties have declined, but they are still at a historical high level. Generally speaking, the supply of agricultural materials is timely, which can meet the needs of spring ploughing production.

　　Water supply will be completed in 2026! The progress of this major water conservancy project benefiting 14 million people is updated.

　　On April 19th, the largest single project of the second phase of the project of diverting water from Han to Wei — — The pylon of Weihe River Pipe Bridge is about to be completely capped, laying a foundation for ensuring that the second phase of the project of diverting water from Han to Wei River will be completed in 2026.

　　The project of diverting water from Han River to Wei River connects the two major water systems of Han River and Wei River, which is one of the 172 major water conservancy projects planned by the country in the 13th Five-Year Plan.

　　The second phase water transmission and distribution project of diverting water from Han to Wei is an important part of the project, which consists of Huangchigou water distribution hub, south trunk line project and north trunk line project, with a total length of 190 kilometers. It undertakes the key task of transporting Hanjiang River water to 21 targets in four key cities, including Xi ‘an, Xianyang, Weinan and Yangling, 11 county-level cities, 1 industrial park and 5 new cities in Xixian New Area on both sides of Weihe River, which is very important for bringing into play the overall benefits of the project.

　　After the completion of the second phase of the project, 1.5 billion cubic meters of water can be transferred from the Han River every year, and a "north-south allocation" water channel has been added to the main skeleton center of the national water network, which plays an important role in realizing the spatial balance of water resources allocation in China and ensuring the high-quality development of economy and society.

In addition, the second phase of the project of diverting water from Han to Wei covers more than 14 million people, which ensures the water supply safety in Xi ‘an, Xianyang, Yangling and Weinan in Guanzhong Plain of Shaanxi Province, and will also greatly solve the contradiction of more water resources in the south and less water resources in the north and provide support for high-quality economic and social development.

Q: Network signal is a concern of users. What kind of planning does Bozhou Unicom have in network construction?

A: Network signals are indeed a concern of users, and China Unicom is constantly strengthening network construction. In 2021, we will further improve the key coverage of 5G networks in urban areas, counties, towns and industrial parks, and plan to build 598 5G base stations. By August 18th, 300 5G base stations had been opened, with a cumulative opening of 699, with an opening progress of 50.17%. It is planned to complete 70% of the 5G base station opening task by the end of August and 100% by the end of October. It is planned to jointly build and share 4G in Guoyang County with Bozhou Telecom in August. After sharing, there will be more than 500 4G base stations in Guoyang County, and both base stations will increase by 40%, forming a common and complete 4G network. By then, network coverage and user perception will be greatly improved.

Q: Is there any discount for Unicom to buy mobile phones now? Please give us a detailed introduction.

A: Now we have optimized the prepaid phone bill to send to the mobile phone. You don’t need to pre-store a large phone bill at one time, just ensure the daily package consumption, and you can enjoy the mobile phone direct drop or 0 yuan purchase activity after more than two years online; For example, if your family accesses the Internet and handles an ice cream package with a price of 159 yuan, as long as you promise to stay online for more than two years, you can get a 5G mobile phone with a price of about 2,300 yuan. Moreover, this package includes 40G national traffic and 700 minutes of national calls, and it can be shared by five people in the whole family. Each person only needs 32 yuan and a 500M-meter broadband, so it can be handled without any additional expenses, which is more cost-effective than pre-storing phone bills to send mobile phones.

Q: Now some friends around me have upgraded the 5G package. How to solve the 5G package if the traffic exceeds?

A: If the traffic is not enough, you can supplement the extra traffic by superimposing traffic packets. For example, you can order a 5G upgrade packet or a monthly traffic packet. The monthly traffic packet will increase according to your online time, and the longer the number is used, the more traffic; If another 5G upgrade package is ordered for one year, you can order popular video members such as iQiyi, Tencent, Youku and Mango tv for only 2.99 yuan per month, which can meet the traffic usage and enjoy more rights and interests. It is very cost-effective.

Q: Recently, I saw that Unicom can handle Gigabit broadband through activities and publicity in various communities. Can users who have already installed broadband directly upgrade?

A: At present, Bozhou Unicom has opened 10 Gigabit broadband communities in the city. You can enjoy Gigabit network speed as long as you apply for an ice cream package of 199 yuan or more. If you are already an ice cream user of Unicom and are using Unicom broadband, you can upgrade to Gigabit network speed directly as long as you go to the business hall to speed up. In order to facilitate the old broadband users, there are preferential activities for speeding up. Old users with a price of 199 yuan or more can speed up their broadband to 1,000 m per month with 1 yuan money, and packages with a price of 129 yuan or more and a price of 199 yuan or less can speed up to 1,000 m per month with 10 yuan. Users who are not ice cream users and speed up during the preferential period can upgrade their original light cats to gigabit light cats for free. For specific speed-up consultation and handling, please contact the surrounding Unicom business offices or consult community promoters.

Q: Recently, some users have consulted the column group and have been using Unicom numbers. What should I do if I want to install broadband?

Answer: You can inquire directly in the nearest business hall. If broadband service is included in your package, you can make an appointment to install it directly. If there is no broadband service, you can change it to a converged package with broadband and get a free broadband. Moreover, at present, for the old users of China Unicom to install broadband, we also give an extra 100 yuan electronic coupon without threshold, which can be used for shopping in Tmall and other shopping malls, which is equivalent to giving 100 yuan money directly. The activity time is limited. If you want to install broadband, you can apply to the nearest business hall as soon as possible, and we will arrange engineers to install it for you as soon as possible.

Q: Last time I heard a friend say that using Unicom broadband sometimes leads to traffic jams. What is the reason? Can you upgrade the network speed?

A: In this case, it is not ruled out that the long-term use of broadband, aging network cable, outdated routing equipment and other reasons may affect the broadband network speed to some extent. Recently, our company is also actively organizing network engineers to carry out public welfare on-site free testing activities in various communities. If it is convenient for your friends, you can also go directly to the nearest business hall or contact the account manager to make an appointment. We will arrange for Zhijia engineers to conduct on-site free testing and provide network solutions. We will comprehensively analyze the home network according to the user’s equipment, package and network environment, and then speed up broadband, replace gigabit routers and network cables according to actual needs, which will completely solve the user’s network problems.

Q: Now you need to open a member to watch videos and use some apps. Is there a package for sending members to Unicom numbers?

A: Yes, if you apply for or change the 5G Instant Ice Cream Package now, you will be given 5GPLUS Gold Edition members for free. You can claim one of the popular app members such as Tencent Video, Iqiyi, Youku, Tik Tok, JD.COM, Mango TV, QQ Music, Netease Cloud Music, Himalayan, Hungry and so on for free every month. If it is not enough to get one member every month, PLUS Gold Members can also buy other membership services at ultra-low preferential prices every month. In addition, there are free video color ring tones, AI voice assistants, exclusive network disks, direct drop coupons for mobile phones, etc. Members of 5GPLUS Gold Edition normally want to go to 29 yuan every month, and the annual fee is only 299 yuan, but the 5G refreshing ice cream package is a free gift to members of Gold Edition, so it is very affordable to use this package.

Question:

1. The mobile phone card is broken. Can I get a replacement card if I don’t go to the local business hall in the field now?

A: Yes, at present, China Unicom’s number supports card replacement in different places. You can apply for card replacement with your ID card at your own business hall.

2. I don’t need the number recently and want to stop. What should I do? What is the charge after the newspaper stops?

Answer: If the mobile phone number is temporarily unavailable, you can go to the business hall with your ID card, provide personal information through the APP client of China Unicom or call the customer service hotline 10010, and charge a monthly fee for 5 yuan/downtime after the suspension. However, you need to be reminded that the account must have enough balance. If the number balance is insufficient, the suspension will be turned into arrears, and the account will be automatically cancelled if the arrears are overtime for three months.

3. Usually, you have to go to the business hall to inquire about telephone bills and bills. Can you inquire by other means?

A: You can download the China Unicom APP, which is the original mobile phone business hall. After logging in with your mobile phone number, you can pay fees, inquire about phone bills, bills, redeem points, etc. China Unicom APP often carries out some preferential activities, so I suggest you pay attention to it.

4. What can be done if broadband is installed on the first floor and the second floor and wireless network cannot be used?

Answer: If your broadband is installed on the first floor, it will be slower to use the wireless Internet on the second floor because of the coverage area of the wireless network. I suggest that you install another router on the second floor, and only need to increase the 10 yuan fee every month, so that the Internet speed on the first floor and the second floor can be guaranteed.

5. When you use Unicom broadband, sometimes you get stuck. What is the reason? Can you upgrade the network speed?

A: Thank you very much for using Unicom’s business. In this case, it is not excluded that reasons such as long-term broadband use, aging network cable and outdated routing equipment may affect the broadband network speed to some extent. Recently, our company is also actively organizing network engineers to carry out public welfare on-site free testing activities in various communities. If it is convenient for your friends, you can also go directly to the nearest business hall or contact the account manager to make an appointment. We will arrange for Zhijia engineers to conduct on-site free testing and provide network solutions. We will comprehensively analyze the home network according to the user’s equipment, package and network environment, and then speed up broadband, replace gigabit routers and network cables according to actual needs, which will completely solve the user’s network problems.

6. There are often some telephone calls to sell real estate. Is the information leaked?

A: Thank you very much for reflecting this problem. Unicom strictly implements the Network Security Law of the People’s Republic of China, the Regulations on the Protection of Personal Information of Telecommunications and Internet Users (Order No.24 of the Ministry of Industry and Information Technology) and other industry regulations, as well as the Measures for the Management of Network and Information Security of China Unicom, and does a good job in protecting customer information. Please rest assured that Unicom will not have the problem of customer information disclosure.

In fact, there are many ways to leak information now. If you have consulted the relevant information of selling houses, renting houses and buying decoration products before, there is a risk of number leakage. It is also recommended that you strengthen your awareness of personal information protection and security every day.

According to the website of the Ministry of Industry and Information Technology on the 9th, during the Spring Festival (January 31, 2022 — February 6), the communication industry earnestly implemented the deployment and requirements of communication support for the Spring Festival and the Winter Olympics to ensure the safe and stable operation of the communication network and create a good environment for digital consumption.

First, mobile data traffic continued to grow rapidly.

The Spring Festival of the Year of the Tiger coincides with the opening of the Winter Olympics, with a strong festive atmosphere. The new way of digital life covers all kinds of social, entertainment and consumption scenes. Driven by this, the mobile Internet access traffic reached 4.349 million TB(1TB=1024GB) in the seven days of the Spring Festival holiday, an increase of 21.7% compared with the seven days of the Spring Festival in 2021, and the growth rate exceeded 20% for three consecutive years; Among them, the first two days of January 31st and February 1st were the peak hours, and the mobile Internet access traffic on that day was 589,000 TB and 654,000 TB, respectively, up by 18.2% and 18.6% year-on-year. At the same time, the substitution of mobile Internet services for calls and short messages has become more apparent. In the seven days of the Spring Festival holiday, the national mobile phone billing time totaled 53.17 billion minutes, down 3% compared with the seven days of the Spring Festival last year. The number of mobile short messages sent nationwide was 20.75 billion, down 2.1% compared with the seven days of the Spring Festival last year, of which the number of mobile short messages sent on January 31st and February 1st was 3.87 billion and 2.95 billion respectively.

Second, take multiple measures to ensure the safe and stable operation of communication networks.

During the Spring Festival guarantee period, basic telecommunications enterprises have invested a total of 237,000 support personnel and more than 30,000 vehicles, and adopted special support measures for epidemic prevention and control, key areas and key routes for holiday activities, including: making plans to deal with personnel flow and centralized business growth, and optimizing network resources allocation and expansion in advance; Do a good job in the service, installation and maintenance of the business hall to ensure the smooth demand of the physical business channels and the timely response of the maintenance channel services; Strengthen inspections and inspections, during which more than 400,000 kilometers of trunk optical cables were inspected and more than 4,600 kilometers of submarine cables were patrolled; Strictly implement the "7×24 hours" special person on duty and the "zero report" system of security incidents, and carry out special monitoring of network security in key areas. Especially during the opening ceremony of the Winter Olympics, based on the unified deployment of the Ministry of Industry and Information Technology, basic telecommunications enterprises cooperated closely with relevant units to successfully complete the tasks of communication guarantee and network security, and achieve the goal of "zero failure" and "zero loopholes".

Third, innovative services continuously improve the user experience

During the Spring Festival, basic telecommunications enterprises actively took measures to benefit the people and facilitate the people, launched cross-regional and off-site integration services for returnees, carried out local New Year traffic gifts for migrant workers, and launched preferential products for the left-behind elderly in rural areas. In terms of improving user experience, efforts should be made to reduce the wireless drop rate of key scenes; Ensure that Internet TV is not stuck during the Spring Festival; Realize the commercial live broadcast of 5G+8K+AVS3 (the third generation audio and video coding technology), and the performance is improved by 40% compared with the international video coding standard (HEVC); Promote the application of high dynamic range video technology in the mobile live broadcast of the Winter Olympics, with the brightness of the picture increased by 40 times and the color range increased by 72%. In terms of innovative services, China Telecom has joined hands with CCTV to create a slow live broadcast activity of "Don’t go home during the New Year, see your hometown on the cloud" and start the "cloud returning home" craze; China Mobile Company provides artificial intelligence real-time subtitle service during the Winter Olympics, and provides artificial intelligence watching experience on the "Mi Mi Video" APP; China Unicom has optimized the digital rural service cloud platform to provide smart rural management and accurate epidemic prevention and control services for more than 140,000 administrative villages.
