The demand for transportation has increased, and the flow of people and cars in urban areas has increased significantly; Restaurants and restaurants have resumed one after another, and the passenger flow in major business districts has increased; The number of tourists in popular scenic spots has rebounded, and the cultural tourism market has shown a recovery trend … … During the New Year holiday, the reporter learned that with the acceleration of resumption of work and production in many places, the life service industry resumed in an orderly manner and market consumption continued to pick up.

　　"Fireworks" Rising, the catering retail market is gradually warming up.

　　During the New Year’s Day holiday, there were long queues at the gates of several restaurants in Guijie Street, Beijing, and many businesses resumed their 24-hour business. "A lot of guests came on the first day of the resumption of dining. Now the business has recovered to 70% before the epidemic. " Ms. Liang, the owner of the three brothers in Beiping, said.

　　Not only Beijing, but also Haidilao Guangzhou Beijing Road Store in Guangzhou Pedestrian Street Scenic Area received reservations during New Year’s Day one week in advance. On New Year’s Eve, there was a queue at the store around 5 pm.

　　During the New Year’s Day, the reporter visited many service-oriented physical stores such as restaurants, cafes and barbershops, and found that the popularity was slowly returning, and the long-lost fireworks in the streets and lanes came back.

　　Driven by catering and retail, many key business districts began to be lively. In the Tianhe Road business district in Guangzhou, which is known as the "No.1 business district in South China", the daily average flow of people continues to recover. The reporter learned from Tianhe Road Chamber of Commerce that the number of people in the business circle exceeded 1 million on the day before New Year’s Day, and more than 100 events were held in various shopping malls around creative arts, national culture, fantasy travel and Tianhe fashion, which attracted many consumers’ experiences.

　　While offline consumption is gradually recovering, online consumption continues to be hot. Take catering as an example. According to the data of Meituan, the online transaction volume of dining hall food in China more than doubled compared with last week two days before the holiday, among which the related transaction volume in Jiangsu and Zhejiang increased by over 230%. In the past week, the sales of "New Year’s Day", "New Year’s Day" and "New Year’s Eve" themed dishes on the public comment list increased by 664% from the previous week.

　　The enthusiasm of consumers has also ignited the confidence of businesses. According to the data of Meituan, during the New Year’s Day, the number of take-away merchants offering New Year’s dishes increased by three times compared with the previous week, and the number of New Year’s related dishes increased by five times.

　　The reporter noted that in order to help the consumer market continue to recover, many places have introduced relief measures and consumption promotion arrangements, among which catering, retail and other service industries have become the focus. For example, the Ningxia Department of Commerce said that it should seize the peak consumption season at the end of the year and the beginning of the year and vigorously promote and hold various consumption promotion activities. Focus on automobile, catering, retail and other key industries, intensively and accurately release government coupons, and do a good job in subsidy payment. At present, the major business districts in Ningxia have fully resumed business, and the passenger flow in shopping malls is increasing day by day.

　　The increase in orders and the increase in the consumption of cultural tourism.

　　Consumer markets such as tourism, leisure and entertainment are also warm and harmonious.

　　During the New Year’s Day, many resort hotels in Sanya, Xishuangbanna and Zhangjiakou Chongli welcomed full rooms. Pullman Sunac Resort Xishuangbanna has a total of more than 400 rooms. One week before New Year’s Day, the popular rooms for the holiday have been snapped up. "Compared with previous years, the stay time and consumption items of guests in the hotel have increased significantly this year." The relevant person in charge introduced.

　　A number of data show that during the New Year’s Day, the popularity of transportation, travel and consumption has been rising.

　　According to the data of FlightAI market insight platform, during the New Year’s Day, major airports basically recovered to the same period of last year, and the passenger traffic of TOP10 airport increased by about 20% year-on-year. According to the data of Flying Pig, the number of train tickets during New Year’s Day increased by more than 2.6 times compared with the same period of last month, reaching the peak in the past six months, of which the inter-provincial train ticket bookings accounted for nearly 60%.

　　The signs of recovery in the tourism market are more obvious. According to the data center of the Ministry of Culture and Tourism, during the New Year’s Day holiday in 2023, there were 52,713,400 domestic tourist trips, up 0.44% year-on-year, and the domestic tourism revenue reached 26,517 million yuan, up 4.0% year-on-year.

　　According to Ctrip’s report, compared with less than 40% of users traveling across provinces in 2022, nearly 60% of users choose to travel across provinces during the New Year’s Day holiday this year. According to the data of the US Mission, the popularity of night play has not diminished, and the New Year’s Eve tickets for characteristic blocks and theme parks have increased by more than 10 times from the previous month. On the flying pig platform, during the New Year’s Day, the number of car rental bookings in popular tourist cities increased by more than three times compared with last month; The number of rooms reserved for star-rated hotels and country houses has increased by over 30%.

　　In addition, in terms of leisure and entertainment, with the orderly opening of cinemas across the country, the box office data of New Year’s Day movies is improving. According to the real-time data of Lighthouse Professional Edition, as of 13: 59 on January 2, the total box office of New Year’s Day in 2023 (December 31-January 2) exceeded 500 million yuan.

　　Recently, the Ministry of Culture and Tourism said that for winter tourism, especially holiday tourism such as New Year’s Day and Spring Festival, efforts will be made on both sides of supply and demand to accelerate the recovery of tourism consumption vitality.

　　Beijing Municipal Bureau of Cultural Tourism launched a new brand of "Beijing Micro-vacation" cultural tourism, and jointly released the first batch of six Beijing micro-vacation destination brands with relevant districts; Shanxi, Luoyang, Henan and other places have launched activities such as ticket concessions and ticket reduction and exemption; Hainan held the Happy Festival of Hainan International Tourism Island in 2022 and distributed 10 million yuan of tourist coupons to the whole country … … Many places have come up with "practical measures" to add strength to the recovery of the cultural tourism market.

　　"New vitality" generate’s service industry recovery can be expected

　　Recently, the the State Council executive meeting deployed a package of policies and measures to stabilize the economy, which achieved results, and promoted the foundation of economic consolidation and stability to keep running in a reasonable range. In terms of service consumption, the Standing Committee of the National People’s Congress proposed "promoting the orderly recovery of service consumption in combination with reality."

　　Industry experts believe that with the gradual recovery of production and living order and the effective implementation of relevant measures, service industry consumption is expected to accelerate recovery.

　　Fu Jiaqi, statistician of the Department of Foreign Trade and Economic Cooperation of the National Bureau of Statistics, believes that with the implementation of measures to further optimize the epidemic prevention and control, the series of policies to expand domestic demand and promote consumption have gradually taken effect, the development resilience of the consumer market has continued to emerge, and the consumer demand of residents will continue to be released.

　　"It is expected that there will be obvious recovery growth in the life service industry in 2023. In terms of consumption content, there is a large room for growth in catering and travel. In terms of consumption patterns, more attention is paid to the combination of online and offline consumption. In the consumer group, the youth group is full of consumption vitality and will become the main force for the innovation and development of service consumption. " Tamia Liu, deputy director and researcher of Market Economy Research Institute of the State Council Development Research Center, told reporters.

　　Service enterprises and related industries are also actively exploring ways out. Taking the catering industry as an example, Yang Liu, president of China Cuisine Association, pointed out that fast food enterprises should correctly and objectively understand the current development environment and their own problems, improve efficiency, reduce costs, scientifically and completely establish and continuously improve their own development models, actively try digital means, improve products and services, expand output value, gain more market space and explore better profit models.

　　Leading by Leading, Realizing Leaping Development

　　Next to the assembly line, sparks are flying. In the workshop of Fujian Branch of Zhejiang Qingshan Steel Pipe in zhouning county, Ningde City, a batch of welded pipes are about to leave the factory.

　　"The products are mainly sold to Europe, America, the Middle East and northern China, and the monthly output can reach more than 3,000 tons." Cai Yongqiang, head of the company, said.

　　Zhouning, the highest mountain county in Fujian Province, once had a weak industrial foundation and weak development conditions. In recent years, zhouning county’s industrial development has made great strides — — The stainless steel deep processing industrial park project introduced in 2019 has a total investment of 5 billion yuan and an annual output value of over 25 billion yuan.

　　The change of Zhou Ning is the epitome of Ningde’s leap-forward development. "More big projects, more hugs ‘ Golden doll ’ , accelerate the leap-forward development. " Since the 18th National Congress of the Communist Party of China, the broad masses of cadres and people in Ningde have kept in mind the entrustment of the Supreme Leader General Secretary, and cultivated and formed four leading industrial clusters with international competitiveness, such as lithium battery new energy, new energy vehicles, new stainless steel materials and copper materials.

　　Nowadays, walking in the land of eastern Fujian, along the mountain to the sea, there is a surge of high-quality development and new vitality everywhere. Led by Contemporary Amperex Technology Co., Limited and ningde new energy, Ningde has become the largest lithium battery production base in the world. In coastal Jiaocheng, the intelligent degree of SAIC Ningde base is the highest in China, and a car is off the assembly line in 53 seconds at the earliest. In Shouning, a mountainous area, Sanxiang’s new material, "old trees grow new branches", joined the zirconium-magnesium alloy industry, actively integrated into the raw material industry chain of lithium batteries, and started a new journey of "accelerating lane change" & HELIP; …

　　Leading by the leader, cluster development. Today’s Ningde, four leading industrial clusters radiate mountains and seas and run through the whole region. Since 2018, the industrial added value of Ningde City has increased by more than 30% annually, and the growth rate has ranked first in Fujian Province for seven consecutive years. In 2021, the output value exceeded 360 billion yuan.

　　Always grasping the development of the real economy, making it stronger, better and bigger, Fujian has continuously built a solid foundation for a modern economic system. In 2021, the added value of industrial enterprises above designated size in Fujian increased by 9.9% year-on-year, and there were 21 industrial clusters with output value exceeding 100 billion yuan.

　　Improve work style and optimize development environment

　　"More than expected!" Huang Danni, secretary of the Party branch of Ke Holdings Inc. (Fuzhou) Technology Co., Ltd., praised the related services for its 42 cooperative brand stores to obtain new business licenses soon.

　　"42 stores are located in 5 districts and counties of the city, with a large quantity and a wide range. According to the normal process, it will take at least half a month to complete all of them. I didn’t expect it to be completed in 10 working days. " Huang Danni said.

　　All this is attributed to the cross-departmental and cross-industry "six-in-one" service model launched by Fuzhou. Enterprises can complete seal engraving, invoice application, "five insurances and one gold" and other businesses in one window. In Fuzhou, the start-up time of enterprises has been reduced from 8.5 working days in 2018 to 3 working hours today. In June this year, Fuzhou upgraded its service again, and the pilot bank outlets assisted in the whole process registration of enterprises, extending the "six-in-one" service to bank outlets.

　　Take the initiative to serve the front, constantly improve efficiency, and the small window writes a vivid footnote for "do it right away, really do it", which reflects Fujian’s unremitting practice of strengthening political construction and promoting the improvement of work style — —

　　"Reception of letters and visits, on-site work, investigation and research, and publicity of the party’s principles and policies", and the unremitting "four grassroots" work system have made cadres smell like dirt, solved people’s worries and warmed people’s hearts;

　　"Entering every family, knowing every family’s feelings, solving every family’s worries, and handling every family’s affairs", the time-honored "Four Families" practice has turned "turning around the wheel" and "looking through the glass" into a real understanding of demands and responding to concerns.

　　"The party’s style of work is the image of the party, and it is a barometer to observe the relationship between the party and the masses and the people’s hearts. For a long time, work style construction is always on the road. " The relevant person in charge of the Organization Department of the Fujian Provincial Party Committee said that Fujian will continue to consolidate and deepen the achievements of political construction and work style improvement, show new vitality with a new style, and establish a new trend of high-quality development in the new era.

　　Guarding History and Inheriting Cultural Memory

　　Rows of arcades are lit by lights, pedestrians and electric cars shuttle among them, street performers blow melodious saxophone music, and thick fireworks rise from snack bars on both sides.

　　This is the corner of Zhongshan Road in Quanzhou. A Zhongshan Road, half the history of Quanzhou, connects many historical sites and cultural memories in Quanzhou. In February 2016, the Quanzhou Municipal Party Committee and the Municipal Government set up a special coordination group for the protection and development of the ancient city to centrally protect and upgrade more than 20 streets and lanes, including Zhongshan Road.

　　Preserve the traditional style, repair the old buildings, and introduce the new format … … Selling batter in Shuimen Lane near Zhongshan Road for more than 40 years, the boss Xie Xiguo witnessed the changes of this street this evening: "The road has become neat and beautiful, and the popularity has become more prosperous, and even his own business is getting better and better."

　　Zhongshan Road witnessed Quanzhou, a national historical and cultural city, as a new act to strengthen cultural protection in recent years. Introduce local laws and regulations to protect cultural heritage by legal means; Construct an echelon of intangible cultural heritage talents and give play to the leading role of inheritors; Establish Quanzhou Haisi Historic Site Volunteer Service Team to normalize and popularize the protection … … One year ago, at the 44th World Heritage Conference, "Quanzhou: the World Ocean Trade Center of China in Song, Yuan and Yuan Dynasties" was successfully listed in the World Heritage List, which became the best proof of Quanzhou’s strengthening of cultural protection.

　　There are many characteristic cultures in Fujian, including Minnan culture, red culture, Zhuzi culture and Hakka culture. In recent years, Fujian has continuously promoted the strategy of strengthening the province by culture, and its cultural undertakings have flourished. According to statistics, at present, the province has five world heritages, ranking second in the country; There are 145 national non-legacy representative projects and 169 national key cultural relics protection units. Eight projects in the province were selected into UNESCO’s non-legacy list (roster).

　　Accelerate medical reform and improve medical services.

　　In the clinic of Gaotang Branch of Jiangle County General Hospital in Sanming City, Fu Mingyu, a villager from Changkou Village, is undergoing knee rehabilitation physiotherapy. This year, the 70-year-old man was diagnosed with knee joint degeneration. "The director of the general hospital visits the branch every month, and I have regular checkups and physical therapy. Now my knee is much better!"

　　Not only that, Fu Mingyu’s personal health electronic file has also been included in the national health management platform of Jiangle County General Hospital, and a health management team composed of county and village medical staff provides integrated services for it. "So many people are in charge of my health, and my heart is steadfast!" Fu Mingyu said.

　　"The medical resources are evenly distributed and flow smoothly, and the medical experience of grassroots patients is naturally improved." Nie Lixiong, president of Jiangle County General Hospital, said.

　　Since the medical reform was started in 2012, Sanming City has experienced "controlling chaos and blocking waste", "establishing regulations and establishing systems", and has now entered the 3.0 version of "preventing diseases and improving health". In 2017, Sanming City set up general hospitals in all counties (cities, districts) to integrate county and rural tertiary medical institutions into a medical community; The medical insurance fund is packaged and paid to the county general hospitals according to the head and the year, "overspending is at your own risk, and the balance is retained" to guide medical services to move forward to the prevention port.

　　"In addition to attending the annual training in the general hospital, I can learn a few tricks when experts go to the countryside for rounds." Talking about the changes after the establishment of the medical community, Gao Fawang, a rural doctor in Changkou Village Health Center of Gaotang Branch, opened his mouth. "My ability has improved a lot, and the services provided to the villagers are more abundant."

　　Nowadays, Gao Fawang spends most of his time carrying a health integrated machine to the village to provide health management services for patients with chronic diseases in the village. "Now take the initiative to serve patients, and the better the health of patients, the higher the income."

　　Promoting Sanming’s medical reform experience, Fujian has accelerated the construction of a graded diagnosis and treatment system, focusing on building two medical service highlands in Fuzhou and Xiamen, and expanding the functions of township hospitals and accelerating the development of community hospitals. At present, the compact medical community has been fully rolled out in the province, and the proportion of primary medical treatment has increased by 4 percentage points compared with 2015.

　　Deepening forest reform and enjoying ecological dividend

　　Wuping County, Longyan City, is full of green eyes. Walking into Jiewen Village, thousands of acres of Ganoderma lucidum were scattered in the forest, and the fallen leaves on the ground were parted, and new life sprouted at the top of the fungus stick.

　　"I have green hills and treasures under the forest." Li Cailin, secretary of the Party branch of Jiewen Village, said excitedly that Ganoderma lucidum has a high income. It was planted in that year and can be harvested twice in that year, but it is also very "precious" and has high ecological requirements. With the help of Ganoderma lucidum, the per capita net income of villagers reached more than 28,000 yuan last year.

　　When I came to Shangzhen Village, bees were flying in the beekeeping yard, and the "sweet" industry brought sweet days.

　　"If the forest grows well, there will be more output under the forest." Zhong Liangsheng, a beekeeper in Shangzhen Village, said that when his father raised a box of bees, he received seven or eight kilograms of honey a year, and now he can receive more than 20 kilograms per box. In the past 10 years, his beekeeping base has grown from one to six, and he also provides bees for other provinces. He took the lead in setting up a beekeeping cooperative. Last year, the total income of the cooperative was more than 13 million yuan.

　　Forest flower, forest fungus, forest fruit, forest medicine, Lin Qin … … Under-forest economy is booming in Wuping. Passion fruit and elephant-hole chicken produced under the forest were put on the state banquet of Xiamen BRICS Conference, endorsing "Fujian flavor"; The output of rich and precious seeds accounts for more than 95% of the country … …

　　Good ecology has stimulated new kinetic energy. After the experience of forest reform in Wuping was extended to the whole province, the Bamin Mountains were activated. Up to now, the forest coverage rate in Fujian Province has reached 66.8%, ranking first in the country for 43 consecutive years. 11 new national nature reserves; Cultivate nearly 10 thousand new types of forestry business entities; Nine reform measures, such as the redemption of commercial forests, have been extended to the whole country. The total output value of the province’s forestry industry increased from 63.59 billion yuan when the forestry reform was implemented to 702.1 billion yuan last year, ranking first in the country.

　　CCTV News:According to the website of National Health Commission, recently, National Health Commission issued a notice on printing and distributing the implementation guide for all novel coronavirus nucleic acid testing organizations (second edition). The full text is as follows:

　　All provinces, autonomous regions, municipalities directly under the Central Government and Xinjiang Production and Construction Corps should respond to the joint prevention and control mechanism of COVID-19 epidemic (leading group and headquarters):

　　In order to effectively cope with the possible epidemic situation caused by Delta mutant in Covid-19 and further improve the implementation ability of nucleic acid testing organization for all employees, we organized experts to revise the Implementation Guide for Nucleic Acid Testing Organization for All Employees in novel coronavirus (Second Edition) based on the previous work practice, and formed the Implementation Guide for Nucleic Acid Testing Organization for All Employees in novel coronavirus (which can be downloaded from the "Medical Administration" section of the website of the National Health and Wellness Commission). Is issued to you, please refer to the implementation.

　　The State Council responds to novel coronavirus.

　　Comprehensive group of epidemic prevention and control mechanism

　　September 8, 2021

　　Guidelines for the Organization and Implementation of novel coronavirus Nucleic Acid Detection for All Staff (Second Edition)

　　Nucleic acid detection is an important means of infection prevention and control in novel coronavirus (hereinafter referred to as Covid-19). In order to guide all localities to do a good job in the preparatory work for Covid-19 nucleic acid detection in large-scale population, ensure the completion of all the nucleic acid detection tasks within the designated area with good quality and quantity within the specified time, and realize "early detection, early isolation, early diagnosis and early treatment", this guide is formulated.

　　I. General requirements

　　Actively respond to the epidemic situation in COVID-19, quickly and efficiently control the epidemic situation, standardize the organization, sampling, testing and reporting of all employees’ nucleic acid testing, and co-ordinate the deployment of nucleic acid testing resources to improve the quality of nucleic acid testing.Cities with a population of less than 5 million should complete the task of nucleic acid detection for all staff within 2 days, and if necessary, they can make overall protection within provinces (autonomous regions and municipalities). Cities with a population of more than 5 million shall complete the task of nucleic acid detection for all staff within 3 days, and may apply for national support if necessary.

　　Second, organize the implementation

　　(a) the party committee and government take overall responsibility. Party committees and governments at all levels take the overall responsibility for the nucleic acid detection work of all staff, coordinate all relevant departments at all levels, coordinate in many ways, and manage in a flat way.

　　(2) Establish an organizational mechanism. Districts and cities are required to set up a nucleic acid detection working group under the local joint prevention and control mechanism, led by the Standing Committee of the Municipal Party Committee, and organize relevant departments such as health, public security, civil affairs, transportation, finance, industry and information technology, publicity, etc., to establish a flat working mechanism, which will be urgently activated in case of epidemic, and coordinate the nucleic acid detection work as a whole. Take residential buildings, natural village groups, schools, institutions, enterprises, companies, markets, hotels, etc. as the smallest units to achieve full coverage and no omissions. Do a good job in the unified purchase and deployment of nucleic acid testing materials for all staff.

　　(3) Formulating a work plan. City, county (city, district) to develop an operable large-scale nucleic acid detection work plan, combining emergency with emergency, and timely carry out early warning screening drills.

　　(four) the formation of the work force.

　　1. Set up teams of nucleic acid sampling, sample delivery, nucleic acid detection, technical support of information platform and corresponding emergency response at all levels, and define the area of responsibility for sampling and detection. When all the people in the province start nucleic acid detection, they can immediately put into work. All emergency teams are guaranteed to be on standby 24 hours a day and make all preparations for starting at any time.

　　2. Set up a nucleic acid sampling supervision team to guide each sampling point in the form of piecemeal contract, standardize sampling, personal protection and cross-infection prevention and control, find and solve problems in time, and ensure high quality and efficiency of sampling.

　　3. Set up a nucleic acid detection supervision team, organize clinical laboratory experts to establish a patrol and supervision mechanism, conduct inspections of laboratories, and supervise third-party nucleic acid detection institutions.

　　4. Set up a special data class to manage nucleic acid detection information in a unified way, determine the flow of nucleic acid detection information, and collect, count and report it by special personnel to improve the efficiency and accuracy of information flow.

　　(5) Overall allocation of resources. Establish a support mechanism for nucleic acid sampling and testing areas in the province, dynamically and comprehensively grasp the basic situation and daily (24-hour) testing capacity of various nucleic acid testing institutions around the country, and make scientific and reasonable deployment according to the needs of the starting place for all nucleic acid testing. When necessary, apply for support from the State Council joint defense and control mechanism.

　　(six) to formulate emergency plans. Each township and community shall set up a special work class, with sufficient staff, comprehensively find out and dynamically grasp the base number of all members of the grid, do a good job in reasonable planning and material preparation of sampling sites, and make clear the layout and staffing of sampling points. Make an emergency plan and conduct drills regularly to ensure that once it is started, it can be quickly organized and carried out on-site sampling in an orderly manner.

　　Third, work preparation

　　(a) to find out the base and establish a ledger. Based on the public security household registration and census data, all districts and cities should pre-register the actual population base and distribution of streets (towns), communities and communities within their respective jurisdictions by means of informationization, and accurately grasp the situation of special populations, the ability of testing institutions, the reserve of nucleic acid testing materials, regional sampling and testing teams, sample delivery personnel and vehicle demand. Establish a work ledger, formulate a clear timetable and road map, and timely check and fill the gaps according to the amount of nucleic acid detection tasks and the existing reserves, so as to ensure that all staff will carry out nucleic acid detection in time when there is an outbreak.

　　(2) Implement the detection capability. Health administrative departments at all levels should master the local medical institutions, CDC and the third-party nucleic acid detection forces that can be quickly mobilized, and do a good job in the reserve of nucleic acid detection capabilities. When an epidemic occurs, the nucleic acid detection force equivalent to 10%-15% of the actual management population can be quickly dispatched to meet the needs of large-scale nucleic acid detection in the whole region.

　　(3) Scientific analysis and accurate screening. According to the epidemic spread trend, taking risk as the guide, the scope of nucleic acid detection is accurately defined and the nucleic acid detection strategy is determined.

　　1. Determine the nucleic acid detection strategy. According to the epidemic spread trend, strengthen research and judgment, scientifically delimit risk areas and dynamically adjust them at the first time. In the early stage of the epidemic, at least three rounds of full-scale nucleic acid testing should be carried out in the case of unknown risk sources; After that, the scope and frequency of subsequent detection were determined according to the comprehensive judgment of the traceability of flow regulation, the scope of community control and the results of nucleic acid detection. In principle, quarantine points and streets or communities where cases have occurred in the last three rounds of nucleic acid testing should be inspected once a day, streets or communities where cases have occurred within 14 days but no cases have occurred in the last three rounds of nucleic acid testing should be inspected every other day, and areas where cases have not occurred within 14 days can be inspected every five days.

　　2. Determine the sampling method. According to the control measures taken by the target population, the sampling method should be determined. Isolation points and other key populations should adopt single sampling and single inspection, with one household and one tube in the closed community (closed to households), and other areas should adopt 5-mixed 1 or 10-mixed 1 to carry out testing according to the actual situation.

　　(4) reasonable dicing and scientific layout. All localities should comprehensively consider the population, geographical transportation, distribution of nucleic acid detection institutions, etc., and plan the layout of sampling points in advance under the guidance of professional departments. The sampling stations should not share the same tent or the same space.

　　1. All localities should comprehensively plan the layout of sampling points according to the population, geographical traffic and the distribution of nucleic acid detection institutions.Reference every 1000-1500 people to set up a sampling point, 500-1000 people to set up a sampling station (all localities can set up according to the actual population of communities, streets, towns, rural areas and suburbs), and in principle, set up sampling points in units of communities.

　　2. Sampling points should be standardized and put into use within 4-6 hours. On the basis of fixed sampling points, grid management mode should be adopted, with community sampling as the main mode, and the layout should be refined and improved by entering schools, enterprises and units, so as to facilitate citizens’ sampling and improve sampling efficiency. Vulnerable groups such as the elderly over 60, pregnant women and the disabled should set up green channels for independent sampling.

　　(five) to strengthen information technology, do a good job of dynamic matching of mining, delivery and inspection.

　　1. Establish a nucleic acid detection information system. All provinces shall co-ordinate the establishment of a nucleic acid detection information system, so as to quickly input information, including the information of the examinee (name, certificate type, certificate number, residential address and telephone number) and sampling information (name of sampling point, district (county), sample number, date and time of sample collection, collection location, type and quantity), and quickly feed back the information of the examinee suspected to be positive. Realize the rapid, accurate and real-time monitoring of information collected, sent, tested and reported in nucleic acid detection, and achieve the whole process management of nucleic acid detection. Before the information system is put into use, stress tests should be conducted in advance according to 30% of the actual population under management to ensure the stability of the information system.

　　2. Do a good job of matching collection, delivery and inspection. Before starting large-scale nucleic acid detection, the matching of collection, delivery and detection should be done well in advance, and dynamic scheduling should be carried out. According to the set sampling ability of sampling points and the actual testing ability of each testing institution, the matching and preparation of dicing sampling and sample delivery should be done in advance. According to the detection progress and rhythm of nucleic acid detection laboratory, samples are sent in batches and dynamically scheduled to make full use of detection capacity and improve detection efficiency.

　　(6) Fully staffed and provided with sufficient materials.

　　1. Prepare sampling medical personnel and information entry personnel in advance, and carry out relevant training. Each sampling station shall include one sampling staff and one information entry staff. Calculate according to the sample of 100-150 people collected by each sampling station every hour, reasonably evaluate the workload and allocate personnel. Sampling medical staff should be familiar with the collection methods of nasopharyngeal and oropharyngeal swabs, and carry out strict training on sensory control. Information collectors should be familiar with the operation process of information system and carry out relevant sensing and control training.

　　2. In accordance with the principle of "rather prepare than use, not available and not prepared", on the basis of fully considering the special weather conditions such as rain, snow, low temperature and high fever, according to the layout of sampling points, arrange material reserves or establish an effective calling mechanism at the sampling points in list and ledger, and keep them nearby to ensure that sampling tubes (single sampling, 5 mixing, 10 mixing) and throat swabs (nasopharyngeal swabs) are used in large-scale nucleic acid detection. The medical consumables required for sampling shall be stored locally according to the local population, and the cities and counties shall uniformly dispatch them.

　　Fourth, the work content

　　(1) Improve information registration. In the preparation stage of the whole staff’s nucleic acid testing, the community (village) is taken as the work unit, and the sampling information of residents within the jurisdiction is collected and registered in advance through various ways, including at least the residents’ names, ID numbers, home addresses (specifically to house numbers) and contact numbers. At the same time, we must do a good job in protecting residents’ information security.

　　(2) Standardize the setting of sampling points. A sampling point can be composed of multiple sampling stations, and a sampling station should include sampling personnel, information collectors, volunteers and other related staff and related necessary materials.

　　1. Personnel preparation.

　　(1) It is necessary to compact the responsibilities of the four parties, scientifically divide the grid, standardize the organizational process, and take residential buildings, natural village groups, schools, institutions, enterprises, companies, markets, hotels, etc. as the smallest units, so as not to lack households and people. Fine organization and management, strictly implement the "1 meter" interval requirements, ensure that residents queue for no more than 30 minutes, prevent people from gathering and avoid cross-infection.

　　(2) Each sampling station shall be equipped with 1-2 sampling personnel. Arrange the rotation of sampling personnel reasonably, and take a rest every 2-4 hours in principle.

Collection and transportation units should optimize the dispatching of transport vehicles, rationally arrange the collection and transportation routes, and do a good job in ensuring the removal and transportation of medical wastes. According to the situation of epidemic prevention and control, when a large number of nucleic acid detection tasks are added, the frequency of removal should be appropriately increased. The temporary storage time of medical wastes in nucleic acid testing institutions shall not exceed 2 days.

　　(4) Strengthen the removal protection. Nucleic acid testing institutions should designate special channels for medical waste handling and use special cargo (building) ladders. Medical waste removal personnel should do personal protection (wear work clothes before handling ordinary medical waste and protective clothing before handling medical waste related to epidemic situation), and wear protective equipment such as protective masks and gloves correctly, and try to avoid contact with other staff during handling. The medical waste removal personnel shall deliver the medical waste to the designated place along the special passage according to the agreed time, and shall ensure that the medical waste does not fall to the ground, and shall not discard or omit the medical waste. It is necessary to clearly inform whether this batch of medical waste belongs to "epidemic-related medical waste" during the transfer process.

　　After each medical waste removal work, the protective equipment of the removal personnel shall be disinfected and managed according to the medical waste, and the contact parts of the removal personnel such as door handles, the environment of the transfer area (such as the special handling passage, the goods (building) ladder, the empty place of the temporary storage place), facilities, transfer vehicles and containers shall be fully disinfected.

Special feature of 1905 film network "I was born to be useful, spin a thousand pieces of silver, all of them come back!."With the impassioned recitation,li pofamous literary pieceInvitation to WineOn the big screen, it turned into an unconstrained visual spectacle, which made people fascinated and shocked.

The new film "Three Wan Li in Chang ‘an" starts from the first Tang poems, and takes the audience back to the bright times when the stars shone thousands of years ago. With the friendship between Gao Shi and Li Bai spanning decades as the axis, it outlines the magnificent group image of the stars in the Tang Dynasty.

The film has a good reputation in the screening stage. As the pioneering work of the "New Culture" series, it is expected to become the next summer animation explosion.

In an exclusive interview with 1905 Film Network, directors Xie Junwei and Zou Jing told us that they hoped to present the Tang Dynasty in an all-round way from the perspectives of scenery, character modeling and etiquette paradigm, and to awaken the cultural genes flowing in the blood with 48 Tang poems and familiar names to convey the romance unique to China people.

"Chang ‘an is an ideal place for poets, and’ Three Wan Li’ is the distance between them and the ideal, and it is also the distance between us and the ideal. Poetry is there, books are there, and Chang ‘an is there. "Three Wan Li in Chang ‘an" is a poem we wrote to the sages, and it is also a spiritual inheritance, "Xie Junwei said.

"Chinese confidant"

As the pioneering work of "New Culture Series" of light-chasing animation, Three Wan Li in Chang ‘an aims to capture shining figures and classic works widely respected in the history of China as creative objects and show the beauty of traditional culture in the form of animation.

The first thing that came to mind was the "Tang Dynasty". "The Tang Dynasty is a self-confident and tolerant dynasty, and Tang poetry is integrated into the blood of everyone. When it comes to Tang poetry, Li Bai will naturally blurt it out," Xie Junwei said.

Everyone knows Li Bai. He is a "Poet Fairy" and "Brewmaster", and he is also a "fallen immortal" who is pure and refined, but these auras also invisibly widen the distance between him and the audience.

The director thought of looking for an "ordinary person" to stare at Li Bai. In this way, another hero — — Gao Shi, a frontier poet, came into being.

"In history, Gao Shi and Li Bai were good friends, and he himself was legendary. Before the age of 50, it was difficult all the way, and it was not until the Anshi Rebellion that he finally achieved great success. It is easier for the audience to bring in his friendship with Li Bai from the perspective of ordinary people. "

Li Bai and Gao Shi, one is a free and wild "fallen immortal" and wrote "oh, how can I gravely bow and scrape to men of high rank and men of high office, who never will suffer being shown an honest-hearted face"; A down-to-earth "worldly person" is determined to "go straight to Chang ‘an and knock on the Tianzi Gate".

The sharp contrast between their personalities and acting styles has become the main source of conflicts in movies and dramas, but behind their different life choices, they all reveal their unremitting pursuit of poetry and ideals.

The two directors interpret their friendship like this: "Li Bai and Gao Shi admire and appreciate each other. When they first met, Gao Shi said that I had never seen such a talented person, such a naive and romantic person, and he admired Li Bai; For Li Bai, after middle-aged sumo wrestling, he said to Gao Shi: The silver saddle shines on a white horse, and it is like a meteor. This poem was written by me according to your appearance twenty years ago, and he is also expressing his appreciation for Gao Shi. "

"Their personalities are so different, but they can be together and become bosom friends. This is the romance of Chinese bosom friends that we want to embody."

One of the externalized forms of this "romance" is the three sumo fights between Gao Shi and Li Bai. Director Zou Jing told us, "The social atmosphere in the Tang Dynasty was very martial, and sumo was a popular form of sports at that time. They have three sumo wrestlers in their lives, from the youthful vigor to the vicissitudes of middle age. The body may have declined but the spirit is still there. We want to create a spiritual transmission that spans time. "

At the scene of the road show, an audience asked the director what kind of feelings besides friendship existed between Li Bai and Gao Shi in the film. The director responded: "In fact, there is no need to define what kind of emotion it is. Li Bai and Gao Shi are very important people to each other, and this state is what we want to express."

"Chang ‘an Three Wan Li"

From the splendid Chang ‘an on the top of the mountain, the beautiful Yangzhou with Erming Moon is Yangzhou, to the Yellow Crane Tower on the first floor of the world, the wonders of the Three Gorges with water and sky, and then to the magnificent scenery of Liangyuan, Tongguan, Songzhou and Jibei. …No wonder some people say that Three Wan Li in Chang ‘an is a vivid Tourism Map of Datang.

In order to create a grand scene of the Tang Dynasty thousands of years ago, the master chose the creative mode of combining data archaeology with field collection. On the one hand, I visited Shaanxi History Museum to observe the sand table map of Chang ‘an City, and referred to a large number of books and ancient paintings to reproduce the prosperous Chang ‘an in the prosperous Tang Dynasty.

On the other hand, they also personally went to Tongguan and Songzhou to collect the wind. Zou Jing recalled, "When we were in Tongguan, we stood on the wall and looked out, and we really understood why Tongguan was easy to defend and difficult to attack; We went to Songzhou and saw its walls and mountains linked together, then we understood the so-called natural barrier of the ancients. Many things have to be visited in person to understand the particularity of its geographical environment. "

Not only that, "Chang ‘an Three Wan Li" is not relaxed in the details of modeling, etiquette and props.According to the director, the crew also specially invited a etiquette guide to help the main creator reproduce all kinds of etiquette among the literati in the Tang Dynasty, such as the representative ceremony of crossing hands, not bumping glasses when touching glasses, the sense of ritual when Li Bai buried Wu Guide, and all kinds of details of "moving, sitting, lying and walking" are well documented.

"We want to present the real Tang Dynasty in detail, not only aesthetically, but also strive to make the audience return to Tang Dynasty at a glance," Xie Junwei said.

In order to restore the style of the Tang Dynasty in an all-round way, the figures in the film also refer to the proportions and shapes of figures in Tang terracotta warriors, murals and ancient paintings, forming a "tang style shape" with a majestic upper body because of its martial arts.

Specific to the two protagonists, Gao Shi has 22 versions, ranging from 8 to 60 years old, and Li Bai also has 15 versions, from youth to old age.

"Li Bai’s middle-aged state is actually the face that we are most familiar with. The inspiration comes from the illustrations next to Tang poetry in primary schools. We first determined that middle-aged Li Bai would use this shape, while Li Bai in his later years wore a plain clothes, like a youth, and returned to the true state."

In addition to the two protagonists, another highlight of the film is Du Fu, a lovely childhood, which is in sharp contrast with the gloomy and sad image of "Poet Saint" in the public impression.

The director said that this familiar and unfamiliar feeling is exactly what they are pursuing. "Is Du Fu a state of compassion from birth?" He was also a naughty and lovely child when he was a child. After he experienced setbacks and experiences, he finally became Du Fu now. This is what we want to express. We want to present these poets and these events to everyone in a more three-dimensional and flesh-and-blood way. "

Childhood du fu

In the director’s view, "Three Wan Li in Chang ‘an" tells the story of Gao Shi and Li Bai’s deep love for each other across time, and it is also a touching chapter in which the stars of the Tang Dynasty rise and fall with the times and realize their life ambitions under the magnificent background of the times.

In a limited time, the master also made famous historical figures such as Wang Wei, He Zhizhang, Zhang Xu, Cui Zongzhi, Wang Changling, Cen Can, Li Yong, Cenfuzi, Dan Qiusheng, Li Guinian, Ge Shuhan, Guo Ziyi, Princess Yuzhen appear in turn, and constructed a vivid picture of all beings in the Tang Dynasty.

"These sages in the movies made their own choices in the face of life setbacks and difficult pressures, which ultimately affected the direction of life. We will encounter the same difficulties they encountered in those years today, and I hope their choices will give the audience strength, which is the core theme of this film, "Zou Jing said.

There are a total of 48 Tang poems in the film, and how to visualize the artistic conception of Tang poems has become a big challenge for the master.

They finally chose Yellow Crane Tower, Jiang Jin Jiu and Yan Ge Xing for presentation, and Jiang Jin Jiu is undoubtedly the most difficult.

Director Zou Jing revealed: "The production cycle of the whole project is three years, and the production time span of" Into the Wine "is close to two years, and one shot has been done for half a year. This poem is particularly rich in emotion, interwoven with Li Bai’s frustration and ambition, grief and heroism, so we decided to present the world in poetry with a surreal expression. "

"Every link of this play is very difficult, from storyboard, design, animation performance, special effects and even dubbing, it is very challenging. It can be said that all our animation imagination and what we have learned are put into this poem."

To reproduce the classics in a visual way, so that poetry can resonate with contemporary audiences across the Millennium, it should also be in harmony with Gao Shi’s finishing line: "Poetry is there, books are there, and Chang ‘an is there."

"This is the origin of our creation, and the spirit of the poets has been handed down into poems." Chang ‘an Three Wan Li "is a work of spiritual inheritance and a poem for the sages."

　　The netizen who wrote "Tianjin Climbing Raiders" took a selfie on the top floor of a building. His behavior was accused of being too dangerous, and the lawyer thought it might be suspected of endangering public order.

　　Recently, some netizens published a "Raiders of Climbing Buildings in Tianjin", which described in detail how to take scenic photos on the rooftops of several high-rise buildings in Tianjin. Once released, the Raiders caused controversy, and some netizens thought that it was too dangerous to enter the roof of unopened high-rise buildings mentioned in the Raiders. Some lawyers said in an interview that shooting on an unopened rooftop may be punished for allegedly endangering public order, which will not only pose a safety risk to themselves but also to others. At the same time, the lawyer reminded that if there is a safety accident, the management or property owner of the building may also be held accountable for management negligence.

　　Netizens wrote "Tianjin Climbing Raiders" on the Internet.

　　Recently, a netizen posted a "Raiders of Climbing Buildings in Tianjin" on Weibo. In the Raiders, the netizen said that he had climbed to the rooftops of high-rise buildings in Tianjin many times to shoot. In the photos posted by the netizen, someone was sitting on the edge of the rooftops of high-rise buildings, which was very dangerous. The strategy of climbing stairs is widely circulated on the Internet.

　　The "Tianjin Climbing Raiders" published by this netizen includes 10 high-rise office buildings or residential quarters in Tianjin, such as Jinzhigu Building and Junlin Building. The raiders include the location of setting up cameras on the rooftop, how to detour upstairs, how to enter the locked rooftop, and how to avoid security suspicion.

　　Some netizens found that the rooftops in some photos lack protective measures and belong to areas that are not open to the outside world. Therefore, it is not only a security risk but also a suspicion of breaking the law to enter the rooftops in this way. Some people are worried that going in and out of the building at will affect the work and life of people in the building.

　　Photographer: I haven’t thought about it if it is illegal.

　　On the 26th, the reporter of Beiqing Daily contacted Mr. Ma, the author of "Tianjin Building Climbing Strategy". He admitted to the reporter of Beiqing Daily that this strategy was made by him, and he had personally climbed all the buildings mentioned in the article. He said that a few years ago, he climbed a building with a senior who loved photography by chance, and he has since enjoyed climbing the building to shoot landscape photography.

　　After accumulating more than one year’s experience in climbing stairs, Mr. Ma summed up his works and experiences and posted them on the Internet. He claimed that the original intention of climbing the stairs was to let more people enjoy the beautiful scenery of Tianjin.

　　In response to questions from netizens, Mr. Ma said that at the beginning of the raiders, he reminded everyone to pay attention to safety and not to do dangerous actions. "I don’t go to dangerous places, such as climbing over the guardrail of Tiantai. I’m not so dead. I will be careful not to influence others when shooting. If people think I have influenced them, I will leave. But to be honest, I really haven’t thought about whether it is illegal. "

　　However, Mr. Ma’s strategy still met with some netizens’ doubts. In a strategy, Mr. Ma said that in order to enter the rooftop, he broke a lock leading to the roof, and then "I heard that the lock on the roof was welded". Some netizens believe that this practice has destroyed other people’s property, and there are security risks.

　　Claiming to have been in a dangerous situation

　　Despite this, Mr. Ma admitted that he had encountered dangerous situations in the process of boarding the rooftop.

　　He mentioned that when he climbed the roof of Chifeng Bridge Community Building, he needed to climb a ladder 3 meters high to go to the roof. "After I went up, I found that the ladder was not strong. When I stood in the middle of the ladder, I hesitated. Is it better to go up or go down?" I was a little weak at the time, but I thought I had come here, so I’d better go up and shoot. "

　　In addition, Mr. Ma told the reporter of Beiqing Daily that sometimes there is a strong wind on the rooftop, and he will always stand in the fence and dare not turn it out.

　　He recalled that at the earliest time, he went to the rooftop of King’s Landing Building to shoot. At that time, many people besides him also filmed on the rooftop. With the increase of people, the security guards will not let people go to the rooftop, and the building has installed a monitor on the rooftop. "If you want to take photos in King’s Landing Building, you can only book a hotel room under the rooftop, so you can still take photos of the corresponding landscape and there is no security risk."

　　For some photos that look dangerous in the Raiders, Mr. Ma said that those "photos that seem to make people’s legs soft" were not taken at risk. "In fact, the place where I am standing is not dangerous, and there is a fence in that position, but if I tilt the camera slightly, I can’t see the guardrail." He said that sometimes when there is a guardrail in the photo, he will PS the guardrail, "it becomes the effect in the photo."

　　Lawyer: Behavior that disturbs public order will be punished.

　　Han Xiao, a lawyer of Beijing Kangda Law Firm, told the reporter of Beiqing Daily that according to Chinese laws, if the act of shooting on the rooftop like Mr. Ma causes the consequences of disturbing public order and endangering public safety, it can be characterized as illegal and punished accordingly.

　　"There is no protective measures to climb to the rooftop to shoot, and the probability of danger is very high. Once an accident is caused, not only is there no guarantee for your own life safety, but there is also a great chance to endanger public safety. If serious consequences occur, they can even be detained. "

　　He reminded the photographer that shooting on the rooftop should be approved by the owner or manager of the building. If the building is damaged during shooting, the owner of the building has the right to ask the photographer for compensation.

　　If the climber has the behavior of breaking the door, it should be analyzed according to the degree of property loss. If the loss is large, he can be punished by administrative detention. If the loss exceeds 5,000 yuan, he may be suspected of intentionally damaging public and private property and will be investigated for criminal responsibility.

　　Han Xiao said that according to the Tort Liability Law, managers of hotels, shopping malls, banks, stations, entertainment places and other public places or organizers of mass activities should bear tort liability if they fail to fulfill their security obligations and cause damage to others.

　　Therefore, once the photographer has an accident when shooting on the rooftop, if it can be proved that the manager or property owner of the building has failed to fulfill his security obligations and there is management negligence, he will bear part of the civil liability caused by it.

BYD’s fifth-generation DM technology is "digging" out for fuel consumption.

technical background

Motor advantage

strong

The instantaneous output peak torque at low speed is large. If the engine is used for high torque output, its related technologies are basically monopolized by relevant manufacturers in Europe and America.

fast

The motor torque adjustment is 20 times faster than that of the engine. At present, there is no gearbox to adjust the conversion torque in the electric drive on the market, and the electric control cycle is only 5ms, while the intake, compression, work, exhaust and power output of the engine take 100ms in one cycle.

So it’s more direct

accurate

Compared with the oil truck, the resolver identification accuracy is 300 times higher, the former is 0.02 degrees, while the latter is 7.5 degrees. Such applications as the ESP function of the chassis system are basically mastered by Bosch.

(B) the advantages of the engine

Steady-state high-efficiency kinetic energy output, that is, the steady-state high-efficiency generator engine and the series mode function in the middle and low speed state, and the steady-state high-efficiency driving in the high-speed cruise stage, while if the speed changes frequently in the middle speed driving, the excess engine energy is recovered by means of motor parallel speed increase or motor charging.

The core of the optimal architecture selection of BYD’s power system (pay attention to the non-planetary gear architecture) lies in how to give full play to the electric driving power and how to dispatch the engine power, as shown in the following figure.

(3) Comparison between PHEV and HEV

The fuel consumption is low. After all, for DM, the engine is only an aid. In most cases, it is only used to generate electricity for extended range when commuting. With high-power motor driving, the driving experience will be much better. At the same time, it has a large battery support and has the function of external discharge.

The fifth generation DM technology

Three major architectures

Power architecture based on electricity

Plug-in special high-efficiency engine: the engine with the highest mass production thermal efficiency of 46.06% in the world, and the improvement measures include

The world’s highest ultra-high compression ratio is 16. For the problems such as knocking and thermal management that may be caused by this, measures have been taken.

In order to improve the oxygen content of intake air, a high tumble port is adopted, and the combustion efficiency is improved by oxygen-enriched environment.

The EGR system is newly designed, and the middle urging is changed to the front urging.

The shape and inner wall of the combustion chamber are specially optimized.

Intelligent EFI system (mentioned again later)

The cylinder block and the cylinder head are cooled separately, and the energy consumption of the engine cooling and cooling system itself is reduced.

An intelligent variable lubrication system is designed to reduce engine friction loss.

Optimization of engine intelligent start-stop strategy

In the process of conventional engine starting, the instantaneous current will be very large when starting with a small battery of 12V, so the engine speed can only be raised in a certain period during the process of pulling the engine; Using high-voltage power electric drive to start can reduce the current and pull up the engine speed more quickly, and also avoid the resonance chattering problem that may be caused by the motor pulling up the engine;

At the same time, in the process of quickly pulling up the engine speed, the rapid power output of the engine itself is ensured by excessive fuel injection.

The energy loss can be reduced by 16%.

Extreme control optimization of system efficiency

By using the power battery as the energy reservoir, the engine can maintain a more efficient working condition as much as possible, and make full use of the driving advantage mainly based on electricity.

EHS electric hybrid system

electrical machinery

Segmented magnetic steel & ultra-thin silicon steel sheet to reduce magnetic loss and eddy current loss.

The double mechanical pumps in the motor cooling system are upgraded to the double pump coupling-rotor oil throwing technology, that is, one mechanical pump and one electronic pump, and the latter is started and stopped as needed, so the cooling process is more detailed.

clutch

The transmission efficiency between the motor and the wheel end is improved, which is transmitted by two gears and bearings. The previous generation adopted cone bearing, which has high strength but low efficiency, so it was upgraded to ball+column bearing and high efficiency clutch.

The motor speed is 16,000 rpm (132 kW, 316N.m) in the previous generation, and now it is 18,000 rpm (120 kW, 210 N.m); And the volume, power and torque of the motor are all reduced, but the power is not weakened, and the output of the wheel end is only amplified by a larger gear ratio.

The comprehensive working condition efficiency is improved by 5%

Insert-mix special blade battery

The energy density increased by 15.9%, the discharge rate increased by 33%, and the energy recovery increased by 20.3%. Because the battery capacity is large, the weight of the vehicle is bound to increase, which puts forward higher requirements for energy consumption. Therefore, part of the solution is made by improving the energy recovery rate, making a small motor mention and weight.

Charging and discharging experience upgrade

The slow charging power is upgraded from 3.3kw to 6.6kw.

DC fast charge for 21 minutes.

The external discharge is increased from 3.3kw to 6kw to meet the needs of more outdoor vehicles.

12V Ferrous lithium phosphate starter battery.

Status decline, especially in the process of vehicle starting, which was originally powered by 12V battery and transferred to electric drive.

The weight dropped from 12kg to 2.2kg

The small battery will have the same life cycle as the whole vehicle, so there is no need to change it frequently, and there is no need for the small battery to be dead.

When the small battery loses power, the power battery will charge it; If the power of the large battery is not enough, it will start the engine stomach power battery to replenish power. So don’t be surprised to see the car parked there and no one suddenly started in the future.

The small battery has its own independent BMS, which is used to communicate with the power battery.

Full temperature range vehicle

Active air intake grille, under the condition of low temperature, when the engine needs to be warmed up, the air intake grille is closed, and the water temperature rises faster; In hot weather, open the air intake grille to exchange heat and improve the heat dissipation in the front cabin; Close the air intake grille at high speed to reduce wind resistance.

Battery thermal management system

The battery direct cooling technology is adopted, and the battery is directly blown by the cooling capacity of air conditioner.

The temperature equalization technology is improved, and the shape of the cold plate flow channel is optimized to make the effective area better. The active temperature equalization technology is used, and the control valve is arranged at the cooling port, which is actively opened when the temperature needs to be lowered, so that the temperature equalization is improved by 45%, the battery activity can be kept in the optimal temperature area better and faster, and the energy consumption is saved by 34%.

The application of pulse self-heating technology, that is, heating through high-frequency charging and discharging between batteries, improves the heating speed by 60%.

Cabin thermal management, through intelligent switch internal and external circulation, actively control the compressor, blower and internal and external circulation switch according to the temperature, light and position (such as tunnel environment) inside and outside the vehicle.

Seven-in-one power domain control, through the improvement of chip and communication speed, strengthens the integration of all components, improves the power density of electric drive system, and improves 18.3%.

Wind resistance of the whole vehicle is 0.26Cd.

Low wind resistance rim

Low drag caliper

The integrated flat chassis, which has been extensively evaluated on the Internet, is no longer an oil-to-electricity structure. The layout and technology of the whole car chassis have been improved a lot, and of course the comfort has also been significantly improved.

Electronic and electrical architecture

Combined with different scenes and different parts of vehicles (such as oil, machinery, electricity, liquid, heat, etc.), the intelligent switching of vehicle modes, intelligent power distribution and intelligent voltage adjustment are carried out through historical massive data and AI technology.

The AI energy consumption mode of the vehicle system will intelligently adjust the power consumption or oil consumption strategy according to the congestion situation and road conditions during the navigation of Gaode map.
