Arithmetic average (Average) is the result of dividing a group of data by the number of data. It is a commonly used statistic to measure the level of data and is often used in parameter estimation and hypothesis testing. For example, the average wage of employees is used to measure the general level of employees’ wages, and the average weight is used to observe whether a certain group of people is overweight or not. Average is widely used, but the calculation method is simple, which is equal to the sum of all the observed values of a variable and then divided by the number of observed values.

　

According to the different data, there are different formulas for calculating the arithmetic mean. The average calculated from ungrouped data is called simple average. Suppose a set of sample data is, the sample size isN, then the simple sample average is usedSaid, the calculation formula is:

　

　

If there are many original data and they are grouped into frequency distribution series, then the weighted arithmetic average should be used to calculate the arithmetic average, that is, the values of each group of variables should be multiplied by the corresponding frequencies, and then added and summed, and then divided by the total frequency. If the data is divided intoK groups, the calculation formula is:

　

　

Municipal Health and Health Committees and Provincial Centers for Disease Control and Prevention:

In order to maintain the polio-free status in our province and prevent the risks of vaccine-associated paralytic poliovirus (VAPP) and circulating vaccine-derived poliovirus (cVDPV), according to the World Health Organization (WHO) and China’s polio eradication strategic plan, combined with the actual situation in our province, and with the approval of the provincial government, it was decided to add the current "2 doses of inactivated polio vaccine (IPV) and 2 doses of bivalent oral attenuated polio vaccine" from January 1, 2023. In order to do a good job in the adjustment of vaccination programs, the relevant matters are hereby notified as follows:

Implementation plan of polio vaccination in Jiangsu Province

In order to keep polio-free in our province and prevent the risks of vaccine-associated paralytic poliomyelitis (VAPP) and circulating vaccine-derived poliovirus (cVDPV), the routine immunization program of polio vaccine for children in our province was changed from "2 doses of inactivated polio vaccine (IPV)+ 2 doses of live attenuated oral polio vaccine (bOPV)" to "4 doses of inactivated polio vaccine (IPV)". In order to guide all localities to do a good job in the adjustment of the polio vaccination program, the "Implementation Plan for Polio Vaccination in Jiangsu Province" is formulated, with the specific contents as follows:

I. Implementation Time

Since January 1, 2023, the routine immunization of polio vaccine for school-age children in our province has been adjusted from "2 doses of IPV+2 doses of bOPV" to "4 doses of IPV".

Second, immunization procedures and vaccination methods

(1) Immunization procedures

1. Children born after November 1, 2022 (inclusive) should be vaccinated according to the adjusted "four doses of IPV" immunization program. Children should be vaccinated with one dose of IPV basic immunization at the age of 2, 3 and 4 months, and one dose of IPV booster immunization at the age of 18 months.

2. Children born before November 1, 2022 shall be vaccinated according to the "2 doses of IPV+2 doses of bOPV" immunization program before adjustment.

(B) IPV vaccination methods

Inoculation dose was 0.5ml, intramuscular injection.

Third, the principle of vaccination

1. In accordance with the principle of "classified implementation, informed consent and residence management", free polio vaccine is given to school-age children who meet the immunization procedures.

2. Before vaccination, the vaccination personnel should ask about the health status of the recipients and whether there are any vaccination taboos, inform the guardians of the recipients of the vaccine varieties, functions, taboos, adverse reactions and on-site observation and other matters needing attention, and truthfully record the notification and inquiry.

3. If the guardian of the recipient voluntarily requests to vaccinate the non-national immunization program vaccine containing IPV components, if the child has completed the whole vaccination of 4 doses of combined vaccine containing IPV components according to the vaccine instructions, it can be regarded as a substitute with the same effect and complete the whole vaccination of the immunization program vaccine.

4. When the follow-up vaccination cannot be completed with the same vaccine from the same manufacturer (including replanting), the follow-up vaccination can be completed with the same vaccine from different manufacturers.

5. For children with late or missed vaccination of polio vaccine, it is enough to replant the corresponding doses, and it is not necessary to start the whole vaccination again.

Fourth, organize the implementation

(A) Division of responsibilities

Polio vaccination work should be under the leadership of health departments at all levels, and vaccination clinics should be responsible for the specific implementation of vaccination within their respective jurisdictions, including informed notification by the recipients and their guardians, vaccination operations according to norms, and information registration, adverse reaction monitoring and data summary and reporting should be done well. Disease control institutions at all levels are responsible for organizing the implementation and technical guidance of vaccination within their respective jurisdictions, implementing the vaccination rate monitoring, adverse reaction monitoring, effect evaluation and data summary and reporting after the adjustment of polio vaccine immunization strategy, and the provincial CDC will do a good job in the procurement, distribution and supply of polio vaccine.

(2) Personnel training

Disease prevention and control institutions at all levels and vaccination clinic staff should carry out multi-level, high-density, full-coverage polio vaccine immunization program adjustment training, including vaccination implementation, vaccine and cold chain management, adverse reaction monitoring and disposal, risk communication, etc., and increase the corresponding content according to the actual work in various places.

(3) Standardize inoculation

All vaccination clinics should master the taboo, caution and precautions in the vaccination instructions in accordance with the requirements of "Guidelines for Vaccination Work" and "Operation Manual for Vaccination in Jiangsu Province", do a good job in health inquiry and notification before vaccination, implement the "three checks and seven to one verification" system, and scan the code for vaccination, so as to ensure the traceability of the whole vaccination process and avoid vaccination errors and accidents.

(D) Vaccine and cold chain management

Disease prevention and control institutions at all levels and vaccination clinics are stored and transported in strict accordance with the storage conditions on the polio vaccine instructions. When receiving polio vaccine, we should check the batch number and quantity of the vaccine and confirm that it is consistent with the batch number and quantity on the delivery unit’s outbound order. At the same time, we should register the inbound and outbound documents and enter them into the information system according to the relevant requirements of Jiangsu province’s immunization program product management. Immunization planning polio vaccine and non-immunization planning vaccine containing polio components should be registered and stored separately, and the storage place should be clearly marked. Maintain the cold chain equipment for storage and transportation of polio vaccine according to the requirements of "vaccination work specification".

V. Monitoring and handling of suspected adverse reaction to vaccination (AEFI)

Vaccination clinics should do a good job of on-site observation after vaccination, and immediately organize emergency rescue and other work for acute severe allergic reactions during observation, and do a good job in monitoring AEFI according to the National Monitoring Plan for Suspected Adverse Reactions of Vaccination, and cooperate with disease prevention and control institutions to carry out AEFI investigations. Disease prevention and control institutions at all levels should do a good job in AEFI case reporting, verification, investigation and data collection according to the requirements of the monitoring plan. For AEFI that needs to be investigated and diagnosed, an expert group for investigation and diagnosis of abnormal reaction of vaccination should be organized in time in accordance with the requirements of "Work Specification for Investigation and Diagnosis of Abnormal Reaction of Vaccination in Jiangsu Province".

VI. Publicity and Media Communication

All localities should carry out publicity and media communication according to the actual situation of this plan and work, focus on the main purpose and significance of immunization strategy adjustment, issue popular science materials, carry out public opinion monitoring and research, strengthen the guidance of media public opinion when necessary, and convey correct information to the public. At the same time, strengthen the skills training of vaccination staff in publicity and communication, scientifically answer public concerns and do a good job in implementation.

　 1905 movie network exclusive feature Today, "Star Trek: Beyond the Stars" finally takes us out of the boring "Protection Month" … …

　

　 As a super IP comparable to Star Wars in the history of science fiction, the Star Trek series has developed from the 1960s to today with more than 700 episodes and more than ten movies. The persistence of half a century has accompanied the growth of generations, and the brain hole that broke through the sky has also inspired countless sci-fi fans who look up at the stars.

　 Although it can’t be said that it is brain-burning, as a hard science fiction work with a huge pattern, there is still a lot of "cold knowledge" in the film that we need to preview. Below, Zi Shijun will clear the fog for you and come one by one (special note: there are wonderful benefits at the end of the article, waiting for you to get it! ）：

[What is the origin of alien creatures? 】

This episode of "The Great Devil" — — Krall (Krall)

If it weren’t for these sexy thick lips, I really can’t see that these two are the same person.

　

　 Although Crow (idris elba) looks like an evil lizard monster, he is actually human.

　

　 Crow, whose real name is Balthazar M. Edison, joined the Military Coalition Command Organization (MACO) in his early years, and fought against Cindy and Romulan successively, rising to at least the rank of school.

　

　 After the establishment of the Star Federation, MACO was absorbed into the Star Fleet. Edison became the first spacecraft to reach warp speed four — — Captain of the Franklin. However, as a veteran who witnessed countless human compatriots being slaughtered by alien creatures in the war, Edison hated the federal foreign policy of advocating tolerance and peace.

　

　 A year later, in 2164, Franklin was sucked away by a wormhole and crashed on the M-class planet Altamid. Only Edison, Anderson Le and Jessica Wolff survived. Edison sent a distress signal, but there was no answer, which made the three people feel abandoned and completely crazy. Edison was determined to destroy the Star Alliance to prove that the ideal of peaceful coexistence would only bring weakness.

Although the bee soldiers are outnumbered, they are mostly brainless children.

　

　 On Altamid, Edison discovered the technology left over from the previous generation of civilization, including killer bees warships and Fengbing army, and an energy conversion mode that can extend his life by absorbing other creatures. So using the Fengchuan army, the three men captured a large number of alien spacecraft and drained their crew for a living. Slowly, the three men are also close to their victims in appearance. During this period, Edison began to call himself Crow, restrained himself as a human being and stopped speaking English.

Crow and Manas: Can you tell who is right when the two brothers stand together?

Protecting the Right and Left: Manas and carrara.

　 Although Crow is outnumbered, the only men who really have brains are Manas and carrara, two "great protectors".

　

　 Manas’s real name is Anderson Le, and carrara’s real name is Jessica Wolff. Like Crow, they were originally human beings, and both served on the Franklin until the Franklin crashed the Altamid star, and their fate was completely changed.

When carrara pretends to be pitiful, the Federation will be fooled.

　

　 During his stay on Altamid, Manas has been helping Crow induce the passing spacecraft to crash, so as to trap survivors and drain their bodies to continue their lives. One of these poor victims is Jiela’s father. The unarmed struggle between Jiela and Manas in the film also stems from this deep hatred.

CCTV News:Mention "bonus hunter", everyone is familiar with it. Now, the word often refers to participating in various preferential activities to save money or profit from it. Some wool can reap benefits, but some wool not only can’t reap benefits, but even it will break the law.

In June this year, a number of company employees were sentenced in a case caused by "bonus hunter".

The incident occurred in a complaint phone call received by a shopping mall. The customer complained about a private car with a license plate number beginning with Su N. After inquiry, the staff found that the car often went in and out of the parking lot of the mall, and all the parking fees were settled in the mobile phone client of the mall by deducting points. What shocked the staff even more was that more than 100 different mobile phone numbers were bound to the name of this car.Moreover, the parking fee of the car is also abnormal, and no parking fee has been paid for almost a month.　

The staff of the shopping mall expanded the search scope and found that there were about 120 vehicles with similar situations, and a large number of different mobile phone numbers were bound to the names of these license plate information. After preliminary estimation, in 2020 alone, the shopping mall lost nearly 370,000 yuan in parking fees.

Next to this shopping mall is an office building where many companies work. Deng, a company employee, parked his car in the underground parking lot of this shopping mall almost every day in order to pick up and drop off customers.

Deng said that the parking rule of this shopping mall is that a car is free for the first hour, and after one hour, it will be charged according to the hourly rate in 10 yuan, with the daily limit of 80 yuan. When a mobile phone number registers a new member on the mobile phone client of the mall for the first time, it can also get 500 points, which can be exchanged for one-hour parking time in the parking lot of the mall.

One day in June 2020, Deng heard from his colleagues that there was a software called "Gathering Codes and Receiving Codes", which claimed that parking for one hour was only 2 cents.

Deng said that if you want to use this software, you have to recharge it first. After the recharge is successful, you can get a strange mobile phone number by clicking the get new number function in the software and selecting the place to park. Next, use this number to register new users of the parking mall. After that, you can return to the software interface of the mall, fill in the verification code obtained by registration, and you can successfully register as a member. At the same time, you can get 500 points sent by this mall to deduct the parking fee.

Operate it once an hour, eight times a day, and spend 1.6 yuan money, you can park your car until after work. And if you pay the parking fee in full, you need 80 yuan. In this way, this software called "Gathering Codes and Receiving Codes" has become an open secret among employees of Deng’s company.　

The staff of the mall reported the case quickly. According to the vehicle data provided by the mall, the police sorted out and determined the owner information of 120 cars involved. After verification, these car owners are almost all staff members in this office building next to the shopping mall. On January 5, 2021, the police launched an operation. In the end, 25 car owners including Deng were listed as suspects in this case.

Car owners were very surprised. Why were they summoned to the police station because of this? First of all, they think it’s just greed, and why greed touches on illegal crimes.

Subsequently, the police conducted further investigations on the software called "Gathering Code and Receiving Code" used by Deng. According to the relevant registration information, the police locked Shimou, the person in charge of this company, and quickly arrested him.

Shimou confessed that he downloaded the original code of the software from a forum registered overseas and developed this code-receiving software.

In June, 2021, the Yangpu District People’s Court of Shanghai successively heard these cases. In the first instance, the court sentenced Shimou, a software developer, to six months’ imprisonment and fined him for the crime of helping information network criminal activities. In the first instance, the court sentenced three car owners to imprisonment ranging from six months to nine months for fraud, all of which were suspended for one year and fined. The investigation and trial of other people involved in the case are still in progress. Deng and other drivers were granted bail pending trial by Yangpu Branch of Shanghai Public Security Bureau because the amount involved did not meet the criteria of criminal law.

　　10moon24On, Chengdu Branch of Chinese Academy of Sciences Youth Promotion Association and Xi ‘an Branch held a member exchange forum in Chengdu. Peng Liling, Deputy Secretary of the Party Group of Chengdu Branch, attended the meeting and delivered a speech.

CCTV News:Since March, the epidemic prevention and control situation in Shanghai has shown signs of "stabilizing and improving". At present, under the premise of implementing prevention and control measures, life service industries such as catering, hairdressing and housekeeping, which are closely related to people’s lives, are accelerating their resumption of work.

At present, it is clear in Shanghai that catering enterprises that meet epidemic prevention conditions can resume eating in the hall. In March, more and more restaurants opened on the streets of Shanghai. This time-honored restaurant has stopped serving table meals and private rooms, and its customers have returned to the past 20%. Regardless of the front office and kitchen, more than 200 staff members all wear masks. The restaurant advocates that guests sit diagonally at a table to ensure the distance. It is also suggested that there should be no more than two people at each table. When the crowd is too large, it will spread the passenger flow to other floors. The reporter saw at the scene that in a special period, public chopsticks and spoons became a new fashion for citizens to eat. In order to cope with the operating pressure, the restaurant actively adjusted and launched the take-away business of in-house food.

Xiang Kaiyu, manager of Guangming Village Restaurant：Try to package some dishes on our table, such as shrimp, spicy chicken, plain duck, yellow croaker with moss, etc. Almost all of them are finished products. Just preheat them a little when you go back.

This week, the first batch of 135 beauty salons in Shanghai reopened. After the hairdressing shop resumed business, there was a steady stream of customers, especially male customers. Merchants consciously limit the flow, and 36 seats are halved to provide services, and the seats are separated by more than one meter. According to the requirements of Shanghai Municipal Commission of Commerce, to get a haircut, make an appointment first to ensure that there is no queue at the door. In the store, the beauty and skin care project is suspended, and dyeing is done as appropriate. Barbers and customers wear masks all the time. And frequent contact with customers, hairdressing tools, disinfection and sterilization can not be relaxed.

Xia Zhengqi, Manager of Shanghai Nanjing Hairdressing Company:The bibs and towels that come into contact with customers are all used once, one for each guest. Our hairdresser also has a clear rule that everyone has two sets.Tools,One set is put in this disinfection box after cutting, all of which are disinfected by ultraviolet rays, and will be wiped with alcohol after taking it out.

Although closed management is still being implemented in various communities in Shanghai, at present, 60 domestic enterprises in the city have resumed work and fully accepted telephone and online appointments. More than 95% of the domestic helpers in this company are foreigners, and the employment rate has recovered to 60%. The company has issued certificates for some foreign employees to return to work, and domestic workers need to be isolated and observed for 14 days after returning to Shanghai, before they can be arranged to take up their posts. You must also carry a health certificate when you take up your post, and hold the green pass code of the government’s "health cloud" or "application code". You can enter the community only after the residents and the community property agree. Under the epidemic situation, the service of "deep cleaning+room disinfection" has been well received by the market.

Li Wei, Chairman of Shanghai Yueguanjia Home Economics Company:We are equipped with protective tools, that is, everyone wears a mask during the whole work. During the work, all our customers’ hand contact points are disinfected, such as mopping the floor, washing rags or soaking dishes and chopsticks, which can be done with disinfection tablets. After the work, especially for the door handles, switches and in the lobby, use spray to disinfect them completely, and then leave the family.

In the future, Shanghai will also guide life service enterprises to strictly implement prevention and control measures, solve practical difficulties such as "lack of epidemic prevention materials" and "employees can’t enter the community" point by point, and promote enterprises that meet the work guidelines to resume work and production in an orderly manner.

On the May 1 ST International Labor Day, many workers stick to their jobs and spend the holidays in labor. China News Agency issued Tang Dehong photo

In China, the spread of local epidemic has been basically blocked, and the epidemic prevention and control has achieved important results in stages. All parts of China have quickly resumed work and production, and several major projects have shown a trend of speeding up. Many projects are still working overtime to catch up with the construction period during the May Day holiday.

No vacation! The navigation project with the largest fluctuation of water level in the world is about to be fully commissioned.

The control project of navigation construction in Wujiang River Basin-Goupitan Navigation Project of Huadian Wujiang Company officially resumed work and will soon enter the stage of comprehensive debugging.

The navigation project of Goupitan Hydropower Station of Huadian Wujiang Company is a key project of Guizhou Province’s integration into the national strategy of "Belt and Road" and "Yangtze River Economic Belt", which has many world firsts: the navigation head is 199 meters, and the upstream navigation water level fluctuates by 45 meters, which is the navigation facility with the highest navigation head, the largest water level fluctuation and the most complicated navigation channel in the world; The first and third vertical ship lifts are launched, which is the largest launched ship lift in China. The second-stage vertical ship lift has a lifting height of 127 meters, which is the largest vertical ship lift in the world at present, more than 10 meters higher than the famous "super elevator" of the Three Gorges Dam.

Goupitan Hydropower Station has a total installed capacity of 3 million, which is a landmark project for the country to implement the strategy of "transmitting electricity from west to east". As of December 31, 2019, the power station has been put into operation for the tenth anniversary, with a cumulative power generation of 79.571 billion kWh and a tax payment of 3 billion yuan, which has greatly promoted local economic development. After the navigation project of Goupitan Hydropower Station is officially put into operation, the "Golden Waterway" of Wujiang River will extend upstream for 137 kilometers, and a 500-ton ship can go straight, transporting materials from Guizhou Zunyi to Chongqing Fuling and merging into the Yangtze River, with a total length of 594 kilometers.

At present, Huadian Goupitan Power Station Construction Co., Ltd., on the premise of doing a good job in the prevention and control of normalized epidemic situation, has made every effort to advance the progress of ship lift equipment debugging and computer room decoration. At the same time, in order to make up for the delayed time, during the May Day period, all the participating units, more than 200 construction managers and construction workers of this project voluntarily gave up their vacation opportunities to prepare for the next first-stage ship lift’s cabin wire rope connection construction and the second-stage ship lift’s drum wire rope hanging.

Chasing the construction period! China Petroleum China-Russia East Line Project launched a hundred-day attack.

The Sino-Russian East Line (Changling-Yongqing) passes through 30 counties and districts in 12 cities in five provinces (cities, autonomous regions) of Kyrgyzstan, Mongolia, Liaoning, Hebei and Tianjin, with a total length of 1,110 kilometers, of which the Changling-Shenyang section has a pipe diameter of 1,422 mm and a line length of 345.6 kilometers. The Shenyang-Yongqing section has a pipe diameter of 1,219 mm and a line length of 764.4 km. There are 9 stations and 48 valve rooms along the line, with 34 large and medium-sized rivers crossing, 34 railways crossing and 105 grade highways (county roads and above) crossing.

At present, the mid-section project has been fully resumed at the end of March and the construction has been accelerated. As of April 26th, 678.482 kilometers (53,908 crossings) of line welding have been completed, and 8 stations have been started.

From April 20th, the first phase of the "100-day attack" battle was launched on the East Line of China and Russia. The goal was to complete the main welding task of the line from April 20th to July 31st, and the comprehensive ergonomics such as anti-corrosion and trench backfilling could meet the requirements of subsequent construction, while the quality, safety and environmental protection were controlled.

Despite the May Day holiday, all the participating units are optimizing and refining the construction organization, striving to recover the construction period affected by the epidemic at the beginning of the year and strive to complete various construction tasks. It is planned to complete a total of 730 kilometers by May 6.

China-Laos Railway Manmai No.1 Tunnel is connected after the festival.

China-Laos Railway is an important part of China’s important international railway passage to Laos and Thailand, and an important infrastructure for Yunnan to integrate and serve the national "Belt and Road" construction and promote interconnection with neighboring countries. The railway starts from Yuxi in the north and ends at Mohan, the border port between China and Laos in the south, passing through Yuxi, Pu ‘er, Xishuangbanna and other cities. The total length of the main line is 508.53 kilometers, and the design speed is 160 kilometers per hour. It is a national railway I electrified railway. After it is completed and opened to traffic, it only takes more than three hours from Kunming to Jinghong, Xishuangbanna Dai Autonomous Prefecture.

Among them, Manmai No.1 tunnel has a total length of 3,605 meters, and the maximum buried depth of the tunnel body is 291 meters. The geological conditions of the tunnel are complex, with the characteristics of "three highs" (high geothermal energy, high geostress and high seismic intensity) and "four actives" (active neotectonic movement, active geothermal water environment, active external dynamic geological conditions and active shallow reconstruction process of bank slope). Due to the complex geological structure, tunnel construction is prone to collapse, falling blocks and other diseases, which makes the construction difficult.

However, the latest news shows that the Manmai No.1 tunnel in China-Laos Railway Station, which was built by China Railway Construction, will be completed from May 5 to 7.

The first large-diameter shield machine of Chinese enterprises overseas started after the festival.

On May 5, local time, the first overseas large-diameter shield project of China enterprises-the "Victory" shield machine of the large shield project in the east section of the third interchange ring road of Moscow Metro will be officially launched.

This project is the first time that a China enterprise has carried out a large-diameter shield project of more than 10 meters in overseas markets. The project adopts the 10.8-meter large-diameter earth pressure shield machine "Shengli" independently developed and manufactured by China Railway Construction, and is scheduled to start on May 5, 2020.

The project is located in the eastern part of Moscow city, with a total length of 2.947 kilometers and a contract value of 5.6415 billion rubles, or about 540 million yuan.

Under the severe epidemic situation in Moscow, all employees of China Railway Construction in China stick to their posts, and make overall plans to promote epidemic prevention and control and engineering construction, which shows the responsibility of Russian enterprises to keep their promises and fulfill their contracts.

The largest wharf project under construction in the Yangtze River completed the main handover after the festival.

Taicang Port Area is an important part of Shanghai International Shipping Center, a hub port for river-sea combined transport, the largest foreign trade port in Jiangsu, the largest container transport port in the Yangtze River, and the first inland river port in China to fully realize harbor management.

The fourth phase project of Taicang Port, undertaken by CCCC No.3 Navigation Bureau, includes four 50,000-ton container berths and related supporting facilities, with an annual design capacity of 2 million TEUs.

Upon completion, the container throughput capacity of Taicang Port will be increased by nearly 50%, which will further enhance the ability of Taicang Port to serve the construction of the Belt and Road and the development of the Yangtze River Economic Belt.

The 70-meter antenna reflector of the ground application system of Mars exploration mission was successfully hoisted.

GRAS-4 antenna (70m) system of National Astronomical Observatory of Chinese Academy of Sciences is the ground application system of the first Mars exploration mission, and it is an antenna developed and built according to the highest international design requirements. Upon completion, it will become the largest aperture antenna in the Mars exploration data receiving system of the National Astronomical Observatory of Chinese Academy of Sciences, and the second largest movable antenna in the world and the largest in Asia, so as to realize data reception and real-time control in the Mars exploration mission.

China Electric Power Network Communication Sub-group No.39 Institute developed and built a 70-meter antenna reflector.

Jing Meng, secretary of the Party branch of Workshop 203 of the Manufacturing Department, the general commander of the installation site, said, "To overcome all kinds of difficulties, we must not only have a strong heart, but also have a strong team." In strict accordance with the requirements of governments at all levels in urban towns, he led the engineering team to actively carry out on-site epidemic prevention work, disinfected and tested the engineering team members and the construction environment to ensure the normal production and living order of the engineering team.

A few days ago, the 70-meter antenna reflector was successfully hoisted, which further promoted the pace of deep space exploration in China.

Toyota: What kind of car is SW4?

　　For Toyota, basically all products sold worldwide are sold in Brazil. Toyota’s performance in the Brazilian market is also relatively strong, ranking seventh among all brands. In the first 10 months, it sold 131,000 vehicles in Brazil, ranking seventh.

　　We still found a car worth talking about at the auto show. This car is called SW4. Many people may not remember the name of SW4, but if you say Fortuner, I believe you will be familiar with it. This model is sold in India, Indonesia, Australia, South America (South America is produced in Argentina) and other markets. Its platform based on Hilux is a hard-core SUV. At present, SW4 is the second generation model, and its interior design has some differences with Hilux. In terms of power, the car is equipped with 2.7L and 4.0L engines.

　　At present, this car can be bought as a parallel imported car in China, but it is still relatively small. However, as cars like Navarra gradually have a certain market, this SW4 may have a partial market if it can come to China. But in today’s increasingly strict domestic emissions, this car may eventually miss out.

　　Toyota Etios is also a relatively unfamiliar face. It is a model positioned under YARiS. Its compact body, simple design and affordable price can meet the needs of many entry-level consumers. In the Brazilian market, the sales volume of hatchback hatchback is more than that of sedan version.

Honda: WR-V can learn about it.

　　Honda’s main products in the Brazilian market are also synchronized with those in China. HR-V, Fit, Feng Fan and Civic are all familiar faces, while (|) may not be familiar to some people. The name WR-V comes from Winsome Runabout Vehicle, which was built on the Fit platform. It made its world premiere at the 2016 Sao Paulo Auto Show and was sold in South America and India.

　　Just as many enterprises have set up R&D centers in China to build exclusive models, this WR-V is a product developed by Honda Brazil and Honda Japan in line with global standards. Its body length is 4000mm and wheelbase is 2550mm, which is the size of a standard small crossover. Its power is powered by 1.2L and 1.5L engines, and its transmission system is matched with a 6-speed manual gearbox.

　　Relying on the main models of globalization and some exclusive products, Honda achieved sales of 110,000 vehicles in Brazil from January to October 2018, ranking eighth. Its sales star is Binzhi, which is also very popular in China, with a sales volume of 41,000, ranking 13th among all passenger cars.

Legal system: some people are happy and others are sad.

　　The situation of Peugeot, Citroen and Renault in the Brazilian market is not the same. Renault performed super well, ranking fifth among all groups, reaching the level of 150,000 vehicles in the first 10 months. The overall performance of Peugeot/Citroen is relatively average, adding up to a little more than 30 thousand, and the PSA Group did not participate in this auto show. At present, it seems that it has not only encountered some difficulties in China.

　　Renault’s good performance mainly depends on Kwid (52,000 vehicles, 8th), Sandero (43,000 vehicles, 11th), Cabin (20,000 vehicles, 29th), Logan and Duster. Among them, our consumers are familiar with the Kabin models currently imported and sold.

　　Kwid is an entry-level model currently sold in India and South America. It has a length of only 3679mm, a wheelbase of 2422mm and a 1.0L engine, and the price can be affordable for most people. Logan and Duster are actually the same models from Dacia. Although Logan is not famous in China, it should be seen in many countries on earth. Because of the promotion of Renault-Nissan Alliance, it is called Renault Logan, Nissan Aprio, Mahindra Verito or Renault Tondar 90 in different markets.

Chery: Voice of China

　　After reading the above-mentioned overseas brands, one force that we can’t ignore is the China brand. At present, Chery has two products on sale in Brazil, namely QQ and Tiggo 2 (Tiggo 3x). The sales momentum of Tiggo 2 is bullish in recent years, and Chery is also expected to exceed 10,000 vehicles in Brazil in 2018.

From November to January next year, Chery will have three cars listed in Brazil one after another.

　　At this year’s auto show, Chery created the largest booth and brought the most important products in China, from Tiggo 2 (Tiggo 3x) to Tiggo 5, Tiggo 5x, Tiggo 7, Tiggo 8, and then to Arrizo 5. All the models participated in the exhibition, which showed the continuous upward strength and momentum of China brand.

Conclusion:

　　As the largest biennial auto show in South America, the Sao Paulo Auto Show still has a lot to watch. For example, there are the latest models on display in the world: the new 3 Series, which was just launched at the Paris Auto Show in October, appeared here, and the Z4 and 8 Series also appeared in full; For example, Mercedes -AMG launched Project ONE, which was stopped by many people. Like all auto shows, the Ferrari booth is surrounded by three floors inside and three floors outside, which seems to confirm that there is a position of the prancing horse in the hearts of fans all over the world … All the exhibition doors here are opened, and we closed the doors for taking pictures more than once, and then were pulled open by the staff … The China brand is constantly exerting its strength and momentum, which are all images that are constantly passing by in our eyes.

　　The Sao Paulo Auto Show and the Brazilian market are a microcosm. There are similarities and differences with our country, but it can be said that only by better understanding the needs of consumers, respecting local consumers and launching suitable products can we really win the market.
