On the evening of March 30th, GAC Chuanqi officially announced the price of S7 at the user party held in Shenzhen. The new car has launched five models, with the guide price range of 169,800-223,800 yuan, and the price has dropped to 154,800-208,800 yuan after combining the national replacement subsidy. As Guangzhou Automobile Chuanqi’s first high-end intelligent driving mass production model, it yearns for S7 to be built based on EV+ new energy platform, positioning the family’s five-seat SUV, so does it have the strength to impact the mid-to-high-end new energy market?

Chuanqi yearns for S7 to adopt the design language of "hiding the front and moistening it", and create the visual tone of "positive atmosphere" through the collision between rounded surfaces and sharp edges. The 2618mm star-shaped ring on the front face integrates 2248 beads, supports 8 kinds of dynamic light language interaction, and cooperates with the zigzag taillight group, which has both scientific sense and recognition.

Chuanqi yearns for the design of the side of S7 body with suspended roof, hidden door handle and 270 flat side window, which strengthens the simple and smooth outline. The D-pillar energy breathing light enhances the sense of car etiquette through green light (charging) and blue light (discharging). In terms of color matching, the new car offers five theme colors inspired by the geographical pole of China: Shuguang Red, Rainforest Green, Haoyue Grey, Obsidian Crystal Black and Blade Shadow White. Chuanqi yearns for S7 with a body size of 4900×1950×1780mm, a wheelbase of 2880mm, and a ground clearance of 200mm, taking into account urban commuting and light off-road scenes, and all the data are also close.

Chuanqi yearns for S7 interior to provide three color schemes of brown, white and black, 270 embracing skyline ambient light and ADiGO 6.0 intelligent cockpit system driven by Qualcomm Snapdragon 8295P chip, which supports four-tone voice interaction and end-cloud integrated AI service. The whole car seat comes standard with ventilation/heating/massage function, and the rear backrest can be adjusted up to 137. With the 17.3-inch 3K ceiling screen, 22-speaker Dolby panoramic sound and electric suction door, it has a "mobile first class" experience.

As the core selling point, Chuanqi yearns for S7 to be equipped with an end-to-end intelligent driving system developed by GAC without drawing. The hardware adopts NVIDIA Orin-X chip (254TOPS computing power), 11 cameras +1 zoom lidar +3 millimeter-wave radar, which can identify 35 main scenes and 357 sub-scenes, covering complex road conditions such as urban roundabout and narrow roads. The automatic parking function is compatible with special-shaped parking spaces and the "car width +0.5m" limit space. It is worth noting that the city NDA intelligent driving function comes standard in the form of "free use for life", and there is no need for late subscription.

Chuanqi yearns for S7 based on EV+ platform. The new car provides dual-mode drive of plug-in+extended range. The 1.5T engine matches single/double motors, and the comprehensive power reaches 392/501 horsepower. The two-wheel drive version of CLTC has a pure battery life of 205km and a comprehensive battery life of 1150km；; The four-wheel drive version has a pure battery life of 180km, a comprehensive battery life of 1020km and a fuel consumption of 5.7-6.5L/100km. It takes only 20 minutes for the magazine battery to support 30%-80% charge quickly, and the 6kW external discharge function expands the camping scene.

In horizontal contrast, the ideal L6 occupies a high position in the market with its luxury positioning and balanced product strength, while Chuanqi yearns for S7 to provide lidar, high-level intelligent driving and leading endurance at a lower price, thus forming dislocation competition. Traditional competing fuel products, such as SAIC Volkswagen Pro, are good at space, but their power performance and intelligent configuration are slightly weak in the new energy camp. Chuanqi yearns for S7 to anchor a sense of high value at a price of 200,000, which is obviously attractive to users.

In addition, 2025 is regarded as the outbreak year of medium and large SUVs of China brand, and Chuanqi yearns for S7′ s domineering design and people-friendly pricing, which has become a rare "cost-effective flagship" in this track. Guangzhou Automobile Chuanqi simultaneously launched an aviation-class service system, including free pick-up and delivery vehicles in 272 cities, 1.2 million+charging pile coverage and 7×24-hour butler service, further strengthening competitiveness. Therefore, on the whole, Chuanqi’s longing for the listing of S7 is not only a concentrated display of Guangzhou Automobile’s technical reserves, but also a reflection of the pragmatic path for local brands to attack the high-end, and challenge the traditional luxury barriers with intelligent and cost-effective two-wheel drive. So whether these advantages can bring more sales and seize the ideal L6 and other new power markets, we will wait and see.

Since the opening of the bicycle lane connecting Huilongguan and Shangdi, 5.24 million people have cycled, contributing more than 1,500 tons of carbon emission reduction. Last year, the Second Ring Road completed the optimization and transformation of the slow-moving system. The width of the non-motorized vehicle lane was more than 3 meters, and the traffic efficiency increased by 25% … These data are only a microcosm of the improvement of the slow-moving system in Beijing. More detailed changes have made the citizens feel more secure when riding and walking, and it has become a social consensus to respect slow-moving gradually.

　

According to the survey data, in 2021, the proportion of slow traffic trips in the central city of Beijing reached a new high in the past 10 years, reaching 47.8%, an increase of 6.9% over 2017, and the citizens’ willingness to travel slowly continued to increase. By the end of 2021, 84.1% of the citizens thought that the slow-moving rectification was effective.

　

According to the plan, this year, Beijing will continue to promote the transformation and upgrading of the slow-moving system, promote the construction of the east extension project and the south exhibition project of bicycle lanes, optimize the slow-moving corridors of the East Third Ring Road and the North Fourth Ring Road, and improve the walking and cycling environment.

"Small actions" achieve "big effects" in improving the slow-moving environment

　

The south exit of Meishi Street is the node connecting Meishi Street and Liangguang Street. There is not only a business district nearby, but also a number of residential communities. There are many cars and people every day. Since August last year, a bicycle-patterned left turn signal light has been added to the signal pole at this intersection. Cyclists who turn from west to north can turn left only by waiting for the green light once, and the passing time is only 15 seconds.

　

Before this, cyclists need to get off at the crosswalk and wait for the signal light twice to completely pass the intersection, which takes at least 3 minutes. In order to speed up, many cyclists will risk cycling through crosswalks, even diagonally crossing and retrograde.

　

At the intersection of Wangfujing Street and Dashamao Hutong, after a series of transformations, the turning radius of vehicles increases, and motor vehicles need to slow down. Both roads have 2.5-meter-wide non-motor vehicle lanes, and bicycles pass smoothly.

　

This change is due to the continuous upgrading of the slow-moving system promoted by Beijing.

　

At the end of 2019, Beijing put forward the transportation development concept of "slow travel priority, public transport priority and green priority", which fully reflected the transformation from "car-oriented" to "people-oriented" in terms of planning, construction, management and law enforcement, and some changes in details made citizens feel more at ease when riding and walking.

　

"It can be said that it has achieved great results with small moves. Since 2021, a total of 74 bicycle intersections have been set up in Beijing, and the traffic flow lines and access rights of motor vehicles, non-motor vehicles and pedestrians have been clarified, and the traffic order at intersections has been significantly improved." Jing Lubo, the first-level director of the Urban Road Management Office of the Beijing Municipal Transportation Commission, said that the transformation of the intersection of Wangjing West Road and Futong West Street is very representative. The original intersection was too large, which led to serious interweaving of people and vehicles. After the transformation, it was reduced from 8,000 square meters to 3,000 square meters, the intersection area was reduced by about 60%, the pedestrian crossing distance was shortened by about 25%, the traffic capacity of motor vehicles at the intersection was improved by about 10.6%, and the queue length of motor vehicles was reduced by about 26.1%. "In Beijing, such big intersections are gradually slimming down." Jing Lubo said.

　

Shijingshan Insurance Industrial Zone is also a typical achievement of Beijing’s slow-moving system transformation. Through the "four-way integration" of waterfront greenway, garden trail, park service road and air corridor, a slow-moving system demonstration zone has been built, attracting many citizens to choose cycling and walking.

More abundant and smooth road choices also make the order in the waterfront greenway better and better. Peng Peng, head of the Road Facilities Section of Shijingshan District Urban Management Committee, said that when the greenway was first opened, there would be electric vehicles driving in, which was a safety hazard. "At that time, we also planned to send more people on duty to discourage them. However, after the slow-moving system of other roads near the river was upgraded, electric cyclists found that it was more spacious and smoother to bypass other roads. Naturally, they did not walk through the greenway. By increasing supply, they also achieved the effect of standardizing order."

　

Carry out the physical examination of slow traffic, and make improvement according to the problems.

　

"What is the current situation of the traffic environment of the slow-moving system? Has the transformation achieved practical results? In what areas can we make efforts in the next step? "

　

These problems are all concerned by Wang Shuling and his colleagues. Wang Shuling is the head of the slow traffic team of Beijing Traffic Development Research Institute and the director of the track institute. Her research in the field of slow traffic and monitoring the results of Beijing slow traffic management will provide reference for relevant departments to formulate policies and determine future action plans. "Slow-moving transformation is not a blank sheet of paper, there will be many difficulties and obstacles, and it is a long-term work."

　

She believes that bicycles are not only a means of travel, but also an important way to alleviate congestion, improve residents’ health, promote street vitality and help reduce carbon emissions. "In the future, the slow traffic environment in Beijing will be more friendly, and the slow traffic will also be deeply integrated with the charm of the city and the health of residents."

　

Starting from 2020, based on the development level of Beijing’s slow traffic and drawing lessons from the advanced experience of international cities such as Copenhagen and London, the transportation department will build a travel effect-oriented evaluation and assessment system for slow traffic services.

　

"In fact, it is to carry out physical examination for our slow traffic system. Only by objectively reflecting the status quo and finding problems can we formulate more targeted upgrading and transformation plans." Wang Shuling said that 2020 is the initial year of Beijing’s slow traffic physical examination. Around the use effect, more than a dozen indicators were set in three dimensions: facilities, management and usage. In 2021, fine-tuning, road tree-lined and other indicators were added, which also reflected the focus on the actual needs and demands of citizens.

　

Through the physical examination of slow traffic, the spatial data information of slow traffic in six districts, Tongzhou District and Economic and Technological Development Zone was formed for the first time. On this basis, the Work Plan for Improving the Quality of Slow Traffic System was studied and formulated for three consecutive years. With the joint efforts of various departments and local governments, 43 projects were formulated and promoted according to the target in 2020 and 2021, and the construction of slow traffic system formed a benign closed loop.

　

The "physical examination results" in 2021 showed that the non-motor vehicle width compliance rate in the core area, Shijingshan District and urban sub-centers all exceeded 80%, with the core area having the highest compliance rate of 83%. At the same time, in recent years, with the continuous improvement of facilities governance and order management, the illegal phenomenon of facilities occupying trails and motor vehicles invading bicycle lanes has been continuously improved. In 2021, the rate of facilities occupying trails decreased by 10.5% compared with that in 2020, and the rate of illegal intrusion of bicycle lanes decreased by 47% compared with that in 2020. A safe and friendly bicycle travel environment has gradually taken shape.

　

Bicycle lanes have contributed 1,500 tons of carbon emission reduction.

　

In Beijing, cycling and walking have become more comfortable, and it has increasingly become a social consensus that cars make way for bicycles and respect slow travel. According to the survey data of the third party, among the international cities with similar population size, the mileage of slow traffic facilities in Beijing ranks in the forefront, and the mileage of bicycle lanes ranks first in the total scale.

　

Among all modes of transportation, cycling can be regarded as a "zero-carbon" travel choice. According to the research data of Beijing Traffic Development Research Institute, bicycle travel can reduce carbon dioxide emissions by 0.17 kg per person per kilometer compared with car travel. The change of travel structure is very important for "carbon neutrality". If a car user switches to cycling, it can reduce one ton of carbon emissions a year, and basically achieve the goal of "carbon neutrality" from an individual perspective.

In 2019, Beijing built the first bicycle lane with a total length of 6.5 kilometers, connecting Huilongguan and Shangdi Software Park. Compared with private cars and buses, it saved travel time by 32% and 50% respectively, which solved the travel problems of a large number of commuters.

　

"Now, cycling is not only a mode of transportation, but also a way of life." Wang Shuling introduced that the operation of bicycle lanes not only provided convenient transportation options, but also cultivated a large number of "iron powder" for bicycle commuting. Up to now, the cumulative usage of bicycle lanes has exceeded 5.24 million person-times, and the average daily riding volume is 4,500-5,000 vehicles/time. According to the calculation of traffic mode transfer of users of bicycle lanes, bicycle lanes have contributed more than 1500 tons of carbon emission reduction.

　

Nowadays, Beijing is promoting the construction of slow traffic demonstration roads to drive more citizens to choose cycling as a green mode of transportation.

　

After the bicycle lane is completed and opened to traffic, the west extension project will continue to be implemented in 2020, and the left turn sign of non-motor vehicles and special signal timing will be added at the intersection for the first time. In 2022, the east extension and south exhibition projects of bicycle lane will be started, and the radiation-driven function of bicycle lane will be completely activated to build a brand-new green commuter corridor.

　

Last year, the optimization and reconstruction project of the second ring auxiliary road slow-moving system was also a "star project". After the reconstruction, the width of non-motor vehicle lanes reached more than 3 meters, the traffic efficiency increased by 25%, and the morning and evening peak riding flow and traffic speed increased by 8% and 5% respectively. The quality improvement projects of slow-moving systems such as the extension line of Dongdan North and South Street and Ping ‘an Street have also been completed one after another, and the whole road has achieved slow-moving priority, smooth riding and proper walking.

Bike-sharing’s annual cycling volume reaches 950 million.

　

Bicycles are "returning" to Beijing, and the service and management measures need to be constantly improved and strengthened.

　

In 2021, the proportion of slow traffic trips in central Beijing reached a new high in the past 10 years, reaching 47.8%, an increase of 6.9% over 2017, and the citizens’ willingness to travel slowly continued to increase. On 51 roads, such as Xinjiekou Outer Street and Tiantan East Road, the number of morning peak rides exceeds 3,000 per hour.

　

The total number of bike-sharing in Beijing is about 950,000, and the daily average number of riders exceeds 2.4 million, making it the best choice for connecting urban rail transit.

　

Since entering Beijing in 2016, bike-sharing has played an active role in connecting the "last mile" of public transport and advocating citizens’ green travel. At present, the number of operating enterprises in bike-sharing has been reduced from 16 in its heyday to 3 in Meituan, Hello and Qingcheng, and the number of operating vehicles has been adjusted from 2.35 million to about 950,000. The compliance rate and dynamic access rate of operating vehicles are above 95%, initially forming a "1+N" pattern with one operating area in the central city and n operating areas in the suburbs, and the vehicle operating area has gradually expanded from the Fifth Ring Road to all administrative districts. In 2021, the annual cycling volume of bike-sharing in the city reached 950 million, and the highest cycling volume in a single day exceeded 4.71 million.

　

In order to continuously standardize the development of the Internet bicycle industry, the Municipal Transportation Commission has established a comprehensive supervision system to promote the healthy development of the industry. In order to standardize the parking of these bike-sharing and promote the integration of the slow-moving system and rail transit, Beijing has completed the construction of 224 bike-sharing electronic fences in 51 key rail transit stations, realizing the settlement of the entry. Up to now, more than 26,000 parking areas have been designated in bike-sharing, and 16 no-parking areas have been publicized in the core area, and the coordinates of all parking areas, no-parking areas and parking management areas have been pushed to enterprise clients to guide citizens to park in an orderly manner. At the same time, through the joint convention jointly launched by operating enterprises and industry associations, the riders who repeatedly violate the rules will be jointly punished, riding will be restricted, and citizens will be guided to regulate their car use behavior.

Compress the space of motor vehicles and return the road to walking and cycling.

　

A survey on the slow-moving system shows that more than 54% of Beijing residents believe that motor vehicle interference is the most important factor affecting riding comfort, among which "illegal parking" and "unreasonable parking space setting" are more intuitive; There is also a survey by relevant departments that nearly 70% of cyclists believe that order is an important factor affecting cycling.

　

Yang Xinmiao, deputy director of Tsinghua University Transportation Research Institute, has been engaged in research work in the fields of green transportation and traffic safety for a long time, and he often chooses green travel modes such as cycling.

　

He believes that it is the key to ensure the smooth and orderly slow-moving system to go its own way. "The sidewalk is for people to walk, and the bicycle lane is for people to ride." In this regard, he put forward a number of specific suggestions: no parking within three parking spaces at intersections, no parking within two parking spaces at bus stops, no parking within two parking spaces at the entrance and exit of residential areas, and shopping malls, schools, hospitals, etc. should help smooth the walking and cycling in front of the door, and motor vehicles should be allowed at night.

　

In order to further protect the right of way, Beijing is gradually rectifying the parking spaces with problems, and continuously strengthening the order management of the slow-moving system and increasing the investigation and punishment of roadside violations of motor vehicles. In the future, new electronic toll parking spaces on roads will also be reviewed in advance, and can only be set if the width of non-motor vehicle lanes is met.

　

Jing Lubo introduced that Beijing has compiled a series of planning documents such as "Beijing Slow Travel System Planning (2020-2035)" to clarify the future development orientation of the slow travel system, and formulated a series of standards and technical rules such as "Technical Guide for Improving Pedestrian and Bicycle Traffic Facilities in Beijing", highlighting the principle of street space allocation with priority on walking and bicycles. It is the first time to reduce the width of motor vehicle lanes to widen bicycle lanes and trails, pay attention to the priority of slow travel at intersections, and set up bicycles.

　

This year, the slow corridor of the East Third Ring Road and the North Fourth Ring Road will be optimized.

　

The work of promoting the construction of slow-moving system continues. In May this year, Beijing successively issued the Traffic Development and Construction Plan of Beijing during the Tenth Five-Year Plan and the Action Plan for Comprehensive Traffic Management of Beijing in 2022, which set clear requirements for improving the slow traffic environment in the future.

　

Jing Lubo told reporters that this year, Beijing will continue to make efforts to improve the slow-moving system. At present, relevant plans are being formulated and improved. "Typical projects include the slow-moving corridor construction projects of the East Third Ring Road and the North Fourth Ring Road, and will continue to optimize bicycle lanes and trails along the route to make green travel smoother and safer."

　

According to the Action Plan for Comprehensive Traffic Management in Beijing in 2022, in 2022, Beijing will continue to optimize and upgrade the green travel environment, and accelerate the construction of Dongtuo (Liangzhuang West Street-Lincui Road) and Nanzhan projects of Huilongguan Bicycle Dedicated Road; Optimize the slow corridor of the East Third Ring Road and the North Fourth Ring Road (Haidian Bridge-Zhixinqiao) to improve the walking and cycling environment; With the goal of building city slow traffic system, which mainly serves commuting, we will speed up the compilation of slow traffic planning and build a slow priority demonstration block, with at least one in the central city, Tongzhou District and Economic Development Zone. At the same time, it will also promote the connection and integration of garden greenways, waterfront roads and urban road slow-moving systems. Build 20 slow-moving boulevards to increase the comfort of walking and riding. Create 21 cycling routes of "Walking in Beijing" to promote the deep integration of slow travel and tourism.

　

If we turn our attention to the long-term goal, Beijing’s expectation for slow traffic is not limited to the traffic field, not only to "build a pedestrian and bicycle-friendly city and form a continuous and safe slow traffic network", but also slow traffic will become a part of citizens’ healthy life.

　

"Beijing Traffic Development and Construction Plan during the Tenth Five-Year Plan" depicts such a picture for the future development of the slow-moving system: in the "last mile" connection of public transportation, walking and cycling will play a greater role; The slow-moving system in the Fifth Ring Road is continuously networked, all eligible roads are divided into non-motor vehicle lanes, and bicycle priority signs are added to all non-motor vehicle mixed roads; Pedestrians will also be safer when crossing the street. Pedestrians will have exclusive safety facilities when crossing the street, and bicycles will no longer need to detour and retrograde when passing. Streets and blocks will also be more suitable for walking slowly. When riding on the road, citizens will enjoy more trees and trees, and the riding environment will be more comfortable and pleasant.

Recently, two successful hedging cases of geological disasters in Ganzhou and Pingxiang, Jiangxi Province in early March were affirmed and praised as typical cases by the Risk Monitoring and Comprehensive Fire Prevention Department of the Emergency Management Department.

The circular pointed out that these are two typical successful hedging cases of village-level initiative, decisive disposal in counties and townships, municipal early warning and forecasting, and provincial forward-looking planning.

Ganxian District, Ganzhou City: 32 people evacuated overnight.

Since March 2, there have been strong lightning and short-term heavy precipitation in Ganxian District of Ganzhou City for several days. At 9: 30 on March 4, Zeng Junbin, the information reporter of disaster risks and hidden dangers in Luotian Village, Shadi Town, found a mountain crack in front of a house where villagers lived in concentration, so he immediately reported it.

"On March 3, there will be the first strong convective weather in our district this year, and all towns and relevant departments should take precautions in advance." Previously, on February 28th, Ganxian Meteorological Bureau produced and sent meteorological information materials to the district party committee, district government and relevant departments. From 12: 00 on March 3, Ganxian Meteorological Bureau issued warning signals of yellow thunder, blue gale and orange hail, which quickly reached more than 6,000 emergency responders and grassroots information workers in the whole region through SMS, WeChat and other channels.

"After receiving the meteorological warning information, we immediately organized village cadres and information reporters to conduct a comprehensive investigation of the risk points of hidden dangers of geological disasters." Ceng Wei Lin, secretary of the Party branch of Luotian Village, said.

At the same time, the Ganxian District Emergency Management Bureau, together with natural resources, meteorology and other departments and the government of Shadi Town, quickly organized experts to rush to the site for investigation, and confirmed that there were cracks more than 50 meters long in the mountain, and there were signs of new cracking and sinking, and landslides might occur at any time, threatening the safety of residents and high-voltage transmission lines under the mountain. The village committee transferred 32 people from 6 households involved in the risk overnight, and set up physical isolation facilities and warning signs in dangerous areas.

"Meteorological early warning information provides an important decision-making basis for us to carry out defense and emergency rescue work in time." Liu Huajun, director of the Flood Control Office of Ganxian District Emergency Management Bureau, said.

Shangli County, Pingxiang City: 17 people successfully avoided danger.

At 12: 35 on March 4, Li Hua, the information reporter of disaster risks and hidden dangers in Fengqiao Village, Chishan Town, Shangli County, Pingxiang City, immediately rushed to 22 groups of geological disasters in Fengqiao Village for inspection after receiving the warning information of strong convective weather.

Li Hua immediately reported the findings in time when he found that the wall of Hu Qingjie’s farmhouse was cracked, the road in front of the house collapsed and the ground showed signs of settlement. "There is a risk of house collapse, which directly threatens the safety of 6 households and 17 people."

Previously, on February 28th, Shangli County Meteorological Bureau predicted through the analysis of meteorological data that the precipitation process was obviously convective from the evening of March 2nd to the 5th, and some towns and villages might experience short-term heavy precipitation, and made meteorological information materials to be submitted to the county party committee, county government, county flood control departments and relevant towns and villages, prompting them to prepare for defense.

"After seeing the meteorological warning information released by the meteorological department in the township work group, I will conduct inspections in the village at the first time." Li Hua said.

After receiving the reported information, the county emergency management bureau and Chishan town government immediately organized cadres to rush to the scene simultaneously and take emergency measures to timely transfer 17 people from 6 households threatened by hedging and properly resettle them.

As of March 5, before the arrival of precipitation, all scheduled transfer personnel were evacuated safely.

　　At the 4th China International Import Expo (China International Import Expo(CIIE) for short), the China market, with a population of over 1.4 billion and a middle-income group of over 400 million, attracted the attention of many trading partners and multinational enterprises. The reporter of Economic Information Daily learned in China International Import Expo(CIIE) that China will make efforts in many aspects to promote consumption upgrading, build a strong domestic market, open up the domestic and international markets at a high level, and share the development opportunities of China with the world.

　　Data show that the total retail sales of social consumer goods in China increased from 20.6 trillion yuan in 2012 to 39.2 trillion yuan in 2020, nearly doubling in eight years. China has become the second largest consumer market in the world, with continuous optimization of consumption structure, rapid growth of sales of upgraded goods, continuous expansion of green, healthy and sustainable consumption and rapid development of service consumption. In the first nine months of this year, China’s Engel coefficient was 29.8%, down 0.7 percentage points compared with the same period last year; Service consumption accounted for 52.3% of residents’ consumption expenditure, up by 2.4 percentage points.

　　At the 4th Hongqiao International Economic Forum "Sub-forum on New Consumption Trends under the New Development Pattern of Double Circulation", Wang Shouwen, Vice Minister of Commerce and Deputy Representative of International Trade Negotiations, said that China has a large market with a population of 1.4 billion and the largest middle-income group in the world. The consumption structure of residents is in the stage of continuous upgrading, with obvious multi-level and diversified demand characteristics, and the consumption market has great potential, strong resilience and sufficient vitality, and has broad development space.

　　Wang Shouwen emphasized that China will unswervingly deepen reform and open wider to the outside world, more efficiently connect the internal and external markets and share essential resources, and promote the steady recovery and sustainable development of consumption, which will not only meet the growing needs of China people for a better life, but also inject more positive energy into the international community. "At present, China is speeding up the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other. Consumption is an important engine of economic development, an important support for promoting high-quality development and achieving high-quality life, and plays an important role in building a new development pattern. " He said.

　　At the opening ceremony of the fourth China International Import Expo(CIIE), China announced that it would pay more attention to expanding imports and promoting balanced trade development; Add import trade to promote innovation demonstration zones, optimize the list of cross-border e-commerce retail imported goods, promote the landing processing of imported goods in border trade, and increase imports from neighboring countries; Promote the integration of domestic and foreign trade, accelerate the construction of an international consumption center city, develop "Silk Road E-commerce", build a modern logistics system, and enhance cross-border logistics capabilities.

　　The continuous release of market potential and the favorable opening-up have further ignited the enthusiasm of foreign-funded enterprises for China’s consumer market. In the food and agricultural products exhibition area, the reporter saw durian in Malaysia, fragrant rice in Thailand, coffee in Colombia, wine in Argentina and beef in Uruguay … … Multinational enterprises bring special products and compete to open the China market with the help of China International Import Expo(CIIE) platform.

　　Some countries organized delegations to participate in the exhibition, and the exhibition organizations in Japan, Denmark, Poland, New Zealand and other countries expanded the exhibition area and organized more small and medium-sized enterprises representing their own characteristics to participate in the exhibition. Among them, only the exhibition area in Central and Eastern Europe exceeds 1,500 square meters, and the number of enterprises exceeds 60.

　　Not only special agricultural products and food exhibits have attracted much attention, but also upgraded electronic products, jewelry and beauty cosmetics have become the highlights in China International Import Expo(CIIE). The reporter saw that in front of the Samsung booth, the latest tablets, smart watches and wireless Bluetooth headsets were all unveiled; Shiseido showcased the company’s cutting-edge technology and its major brands, and explored investment opportunities in China’s beauty and health fields; Deluca Jewelry has brought many sets of new jewelry, and regards China International Import Expo(CIIE) as an ideal platform to show brands and products to the China market … …

　　The demand for market upgrading in China has also become the driving force for enterprise innovation. According to Xie Weibo, member of Danone’s global executive committee and president of China and Oceania, consumption in China is escalating, and consumers have great demand for health and natural products. "In order to keep up with the pace of China, Danone has established an open laboratory for life nutrition in China, paying more attention to promoting the development of local science and technology and innovating for the China market." Xie Weibo said.

　　Huang Degui, president of Samsung in China, said that Samsung is very optimistic about the market prospects in China. It is understood that as a company that has participated in China International Import Expo(CIIE) for four consecutive years, Samsung, driven by innovation, continues to show the industry the cutting-edge technologies that will lead the future development, and enrich the expectations of China consumers for a better life through innovative products.

　　Kentaro Fujiwara, CEO of Shiseido China, stressed that Shiseido, as an international beauty group based on the 40th anniversary of China, continues to be optimistic about the development prospects of the China market. "We will take a two-pronged approach to seize development opportunities by adding a series of strategic measures of local R&D and introducing global innovation." He said.

　　Wei Wang, director of the Institute of Market Economy of the State Council Development Research Center, said that in the process of accelerating the construction of a new development pattern, consumption has become the core driving force, key link and important hub of the dual-cycle development, providing huge market opportunities for global multinational companies. At the same time, there are a large number of new consumption demands in China market, which provides rich application scenarios for scientific and technological innovation of global enterprises, and is conducive to promoting the innovation and development of domestic and foreign enterprises and upgrading the industrial structure.

"Rapidly increasing traffic" and "getting more money every day" are all gimmicks to reveal the "short video window with goods" scam.

Nowadays, short-sighted band goods are very popular, and many people also have the idea of live broadcast with goods. Some criminal gangs use short video accounts to operate teaching packages, and cutting a video can quickly increase traffic and make more money, laying a scam.

Fictitious traffic success stories trick users into buying high-priced packages.

Xiao Gan of Shenzhen, Guangdong Province fell into the trap. Xiao Gan bought a set meal from a so-called short-sighted band cargo team and successfully opened a window and set up a small shop online. So, can he get the benefits he expects?

Victim Xiao Gan: After buying it back, I found it very difficult to study the course. As long as I bought their more advanced package, I didn’t need to operate it. Someone would help me to run this account, send videos and run my window. I thought at that time that I had paid more than 2,000 yuan, and if I could really reach that income, I could. Then I bought an upgrade package, totaling more than 9000.

However, this so-called short-sighted band cargo team’s promise to Xiao Gan is in great contrast with reality.

Victim Xiao Gan: At the beginning, the account did have a little profit, but not much. Then I asked him, and they gave me a lot of reasons to say that the market was not good.

Xiao Gan, who realized that something was wrong, began to contact the other party to refund the money. However, I didn’t expect the other party to change his previous enthusiasm and refused Xiao Gan’s request very strongly.

Victim Xiao Gan: They said that we signed the contract. If we signed the contract, I was helping you run it, but the effect could not be fully predicted. I thought I should have been cheated, so I called the police for help.

Xu Maofu, a policeman of the Criminal Police Brigade of shenzhen public Longhua Branch: These effects promised by them in the contract have not been realized at all so far, and the marketing means are in line with the situation of fraud.

The investigation shows that this group has great suspicion of fraud, and the main criminal of the gang is Zhong. So what is the actual operation of this gang? After investigation by the police, they found that the company was located in an office building in Longhua District, Shenzhen, and the division of labor among gang members was very clear.

Xu Maofu, a policeman of the Criminal Police Brigade of shenzhen public Longhua Branch: One is the sales department, the other is the operation department, the other is the after-sales department, and the last is the teaching department, which is composed of these four departments. Sales is responsible for attracting customers, and the operation is to help these victims run his online shop, but in fact they don’t know how to operate, so the company doesn’t need many people in this area, mainly in the sales department. Their employees go to work like normal employees. You can’t tell from the appearance that this is a fraud company.

After grasping the conclusive evidence, the police handling the case decided to arrest the criminal gang.

Xu Maofu, a policeman of the Criminal Police Brigade of Longhua Branch of shenzhen public: On July 20th, a net-closing operation was launched, and 45 people were arrested in total. At present, the funds involved in the case have been frozen to more than 3 million yuan.

After the suspect arrived, the police decided that this was a new type of fraud case. However, the criminal suspect’s fraud method is very similar to the online shop fraud that occurred frequently many years ago, and it is a brand-new deformation of online shop fraud.

Chen Zhuowei, a policeman of the Criminal Police Brigade of shenzhen public Longhua Branch: In the drainage stage, they will promote their company on some short video platforms, so that some people can watch these short videos and think that this company is very powerful.

After the victims pay the first sum of money, the suspects will induce these victims to continue to invest.

Xu Maofu, a policeman of the Criminal Police Brigade of Longhua Branch of shenzhen public: The initial amount is more than 2,000, and it can be upgraded to 9,800 later, and the highest one can be upgraded to the flagship version of 26,800 yuan. They will say that you have invested more than 2,000 yuan at present, and how many fans you have, and then a video broadcast may also exceed 10,000. He said that only when you invest more money can you achieve better operational results. Some victims often hold on to it. Since they have invested some money and hope to make greater profits, they think it is better to gamble again.

However, no matter how invested, the goods in the victim’s short video window can never reach the sales volume advocated by the criminal suspect.

Xu Maofu, a policeman of the Criminal Police Brigade of Longhua Branch of shenzhen public: When the victim felt cheated, he expressed strong dissatisfaction, and even when he wanted to call the police to defend his rights, they were forced to find their own employees to buy his products for the corresponding victims and make some sales, and then asked the company to make some fake fans and make some broadcasts to stabilize the victim.

At present, the suspect involved in the case has been criminally detained by the public security organs according to law, and the case is under further investigation. The police reminded that we must be vigilant about online projects that promise high returns and get rich quickly.

Influenza diagnosis and treatment plan

(2018 revision)

Influenza (hereinafter referred to as influenza) is an acute respiratory infectious disease caused by influenza virus, which breaks out and spreads all over the world.

The onset of influenza is acute, although most of them are self-limited, but some of them can develop into severe influenza due to complications such as pneumonia, and a few severe cases progress rapidly and may die due to acute respiratory distress syndrome (ARDS) and/or multiple organ failure. Severe influenza mainly occurs in high-risk groups such as the elderly, young children, pregnant women or those with chronic basic diseases, and can also occur in the general population.

The results of previous influenza surveillance in China show that China is about to enter the influenza epidemic season. In order to further standardize and strengthen the clinical management of influenza, reduce the occurrence of severe influenza and reduce the mortality rate, this diagnosis and treatment plan is formulated on the basis of the Influenza Diagnosis and Treatment Plan (2018 Edition), combined with recent research results at home and abroad and previous experience in influenza diagnosis and treatment in China.

I. Etiology

Influenza virus belongs to orthomyxoviridae and belongs to RNA virus. According to nuclear protein and matrix protein, it can be divided into four types: A, B, C and D.

At present, people are mainly infected with H1N1 and H3N2 subtypes of influenza A virus and Victoria and Yamagata strains of influenza B virus.

Influenza virus is sensitive to common disinfectants such as ethanol, iodophor and tincture of iodine. Sensitive to ultraviolet rays and heat, it can be inactivated at 56℃ for 30 minutes.

Second, epidemiology

(1) the source of infection. Influenza patients and recessive infected people are the main sources of influenza infection. It is contagious from the end of latent period to the acute period. Viruses generally detoxify in human respiratory secretions for 3-6 days, and children and patients with impaired immune function can detoxify for more than 1 week.

(2) means of transmission. Influenza is mainly spread by droplets such as sneezing and coughing, and is directly or indirectly infected by mucous membranes such as mouth, nose and eyes. Contact with items contaminated by viruses can also be infected through the above channels.

(3) Susceptible population. People are generally susceptible. Vaccination with influenza vaccine can effectively prevent influenza virus infection of corresponding subtypes.

(4) High-risk groups of severe cases. The following people infected with influenza virus are more likely to develop into severe cases, so they should be given great attention, treated with antiviral drugs as soon as possible, and tested for influenza virus nucleic acid and other necessary examinations.

1. Children under 5 years old (children under 2 years old are more likely to have serious complications);

2. Older people over 65 years old;

3. Those who are accompanied by the following diseases or conditions: chronic respiratory diseases, cardiovascular diseases (except hypertension), nephropathy, liver diseases, hematological diseases, nervous system and neuromuscular diseases, metabolic and endocrine system diseases, and immunosuppression (including immunosuppression caused by immunosuppressants or HIV infection);

4. Obese people [body mass index (BMI) is greater than 30, BMI= weight (kg)/ height (m) 2];

5. Pregnant and perinatal women.

Third, the pathogenesis and pathology

(1) Pathogenesis. Influenza A and B viruses initiate infection by binding HA to the surface of respiratory epithelial cells containing sialic acid receptors. Influenza virus enters cells through endocytosis, and the virus genome is transcribed and replicated in the nucleus. A large number of new progeny virus particles were replicated, which spread through respiratory mucosa and infected other cells. After influenza virus infects human body, it can induce cytokine storm, lead to systemic inflammatory reaction, ARDS, shock and multiple organ failure, and children may have acute necrotizing encephalopathy.

(2) Pathological changes. Pathological changes are mainly manifested as cluster shedding of ciliated epithelial cells in respiratory tract, metaplasia of epithelial cells, congestion of mucosal cells in lamina propria, edema with monocyte infiltration and other pathological changes. Diffuse alveolar damage can occur in severe pneumonia. Diffuse congestion, edema and necrosis of brain tissue occur when encephalopathy is complicated. Acute necrotizing encephalopathy in children is characterized by symmetrical necrotizing lesions mainly in thalamus, and there is no obvious inflammatory reaction in the local area. Inflammatory reactions such as myocardial cell swelling, interstitial hemorrhage, lymphocyte infiltration and necrosis occur when heart damage is complicated.

Four, clinical manifestations and laboratory examination

The incubation period is usually 1-7 days, mostly 2-4 days.

(1) Clinical manifestations. The main symptoms are fever, headache, myalgia and general malaise. The body temperature can reach 39-40℃, and there may be chills and chills, accompanied by systemic symptoms such as sore muscles and joints, fatigue, loss of appetite, and often sore throat, dry cough, nasal congestion, runny nose and post-sternal discomfort. Facial flushing, conjunctival congestion.

Some of them are characterized by vomiting, abdominal pain and diarrhea, which are common in children infected with influenza B.

Without complications, the course of the disease is self-limited. After 3-4 days of onset, the body temperature gradually subsides and the general symptoms get better, but it usually takes 1-2 weeks for cough and physical recovery.

(2) Complications. Pneumonia is the most common complication of influenza. Other complications include nervous system damage, heart damage, myositis, rhabdomyolysis syndrome and septic shock.

1. Pneumonia

Pneumonia complicated by influenza can be divided into primary influenza virus pneumonia, secondary bacterial pneumonia or mixed pneumonia. The illness worsened 2-4 days after the onset of influenza, or worsened after the recovery of influenza, with high fever, severe cough, purulent sputum, dyspnea, moist rales in the lungs and signs of lung consolidation. The total number of white blood cells and neutrophils in peripheral blood increased significantly, mainly streptococcus pneumoniae, Staphylococcus aureus and Haemophilus influenzae.

2. Nervous system injury

Including encephalitis, meningitis, acute necrotizing encephalopathy, myelitis, Guillain-Barre syndrome, etc.

3. Heart damage

Heart injury is not common, mainly myocarditis and pericarditis. It can be seen that creatine kinase is elevated and ECG is abnormal, and heart failure may occur in severe cases. In addition, the risk of hospitalization and death related to myocardial infarction and ischemic heart disease increased significantly after being infected with influenza virus.

4. Myositis and rhabdomyolysis

The main symptoms are myalgia, myasthenia, renal failure, increased serum creatine kinase and myoglobin, and acute kidney injury.

5. Septic shock

It is characterized by high fever, shock and multiple organ dysfunction.

(3) Laboratory inspection.

1. Peripheral blood routine: the total number of white blood cells is generally not high or low, and the lymphocyte count in severe cases is obviously reduced.

2. Blood biochemistry: hypokalemia occurred in some cases, and creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase and creatinine increased in a few cases.

3. Etiology related examination:

(1) Detection of virus nucleic acid: Detect influenza virus nucleic acid in respiratory tract samples (throat swab, nose swab, nasopharyngeal or tracheal extract, sputum) by RT-PCR (preferably real-time RT-PCR). The specificity and sensitivity of virus nucleic acid detection are the best, and it can distinguish virus types and subtypes.

(2) Virus antigen detection (rapid diagnostic reagent detection): colloidal gold and immunofluorescence can be used for rapid antigen detection. Because the sensitivity of rapid antigen detection is lower than that of nucleic acid detection, the interpretation of the results of rapid antigen detection should be combined with the patient’s epidemic history and clinical symptoms.

(3) Serological detection: The dynamic detection of IgG antibody level in recovery period is 4 times or more than 4 times higher than that in acute period, which has retrospective diagnostic significance.

(4) Virus isolation and culture: influenza virus was isolated from respiratory tract samples. During the influenza epidemic season, patients with negative rapid antigen diagnosis and immunofluorescence detection of influenza-like cases are advised to isolate the virus.

(4) Imaging findings. Imaging examination of patients complicated with pneumonia showed patchy, ground glass shadow and multilobal exudative lesions in the lung; Those who progress rapidly can develop into diffuse exudative lesions or consolidation in both lungs, and pleural effusion can be seen in some cases.

In children complicated with pneumonia, the patchy shadows in the lungs appear earlier, with multiple and scattered distribution, which is easy to be inflated, and the imaging manifestations change rapidly. When the disease progresses, the lesions expand and fuse, and signs such as pneumothorax and mediastinal emphysema may appear.

V. Diagnosis

The diagnosis is mainly combined with epidemiological history, clinical manifestations and pathogenic examination.

(1) Clinically diagnosed cases. The above-mentioned clinical manifestations of influenza have epidemiological evidence or positive detection of influenza rapid antigen, and other diseases causing influenza-like symptoms are excluded.

(two) to determine the diagnosis of cases. Have the above-mentioned flu clinical manifestations, and have one or more of the following pathogen test results positive:

1. Influenza virus nucleic acid test is positive.

2. The isolation and culture of influenza virus were positive.

3. The level of influenza virus-specific IgG antibody in acute phase and recovery phase increased by 4 times or more.

Six, severe and critical cases

(a) one of the following circumstances is a severe case.

1. Persistent high fever > 3 days, accompanied by severe cough, expectoration of pus, blood sputum, or chest pain;

2. Rapid breathing, dyspnea and cyanosis of the lips;

3. Mental changes: unresponsiveness, lethargy, restlessness, convulsions, etc.

4. Severe vomiting, diarrhea and dehydration;

5. pneumonia;

6. The original underlying diseases are obviously aggravated.

(two) one of the following circumstances is a critical case.

1. Respiratory failure;

2. Acute necrotizing encephalopathy;

3. Septic shock;

4. Multiple organ dysfunction;

5. There are other serious clinical conditions that need to be monitored and treated.

Seven, differential diagnosis

(1) The common cold. The general symptoms of influenza are more serious than the common cold; Tracking the epidemiological history is helpful for identification; The influenza pathogen test of the common cold is negative, or the corresponding evidence of infection pathogen can be found.

(2) Other types of upper respiratory tract infections. Include acute pharyngitis, tonsillitis, rhinitis and sinusitis. Infection and symptoms are mainly confined to the corresponding parts. The local secretion was negative for influenza etiology.

(3) Other lower respiratory tract infections. Influenza with cough symptoms or complicated with tracheobronchitis should be differentiated from acute tracheobronchitis; Pneumonia should be differentiated from other pneumonia, including bacterial pneumonia, chlamydia pneumonia, mycoplasma pneumonia, viral pneumonia, fungal pneumonia and tuberculosis. According to the clinical features, a preliminary judgment can be made, and the diagnosis can be made by pathogenic examination.

Eight, treatment

(1) Basic principles.

1. The clinically diagnosed cases and confirmed cases should be treated in isolation as soon as possible.

2 hospitalization standards (meet one or more of the following standards):

(1) women in the middle and late pregnancy and perinatal period.

(2) The basic diseases are obviously aggravated, such as chronic obstructive pulmonary disease, diabetes, chronic cardiac insufficiency, chronic renal insufficiency and liver cirrhosis.

(3) Meet the diagnostic criteria for severe or severe influenza.

(4) accompanied by organ dysfunction.

3. Non-hospitalized patients are isolated at home and keep the room ventilated. Get enough rest, drink plenty of water, and the diet should be easy to digest and nutritious. Closely observe the changes of the disease, especially children and elderly patients.

4. High-risk groups infected with influenza virus are prone to severe influenza. Early antiviral treatment can alleviate symptoms, reduce complications, shorten the course of disease and reduce mortality.

5. Avoid blind or improper use of antibacterial drugs. Use antibacterial drugs only when there are indications of bacterial infection.

6. Children should avoid aspirin or aspirin-containing drugs and other salicylic acid preparations.

(2) symptomatic treatment. People with high fever can carry out physical cooling or apply antipyretic drugs. Patients with severe cough and expectoration are given antitussive and expectorant drugs. According to the degree of hypoxia, oxygen therapy is carried out in an appropriate way.

(3) antiviral treatment.

1. Timing of anti-influenza virus treatment

Patients with severe or high-risk factors of severe influenza should be given anti-influenza virus treatment as soon as possible, without waiting for virus test results. Antiviral treatment within 48 hours of onset can reduce complications, mortality and hospitalization time. Severe patients with onset time over 48 h can still benefit from antiviral treatment.

Patients who are not severe and have no high risk factors for severe influenza may also consider antiviral treatment within 48 hours after the onset of the disease and after evaluating the risks and benefits.

2. Anti-influenza drugs

Neuraminidase inhibitor (NAI) is effective for influenza A and B..

(1) oseltamivir (capsule/granule): The adult dose is 75mg each time, twice a day. Children aged 1 year and above should be given drugs according to their weight: those weighing less than 15Kg should be given 30mg twice a day; Those who weigh 15 ~ 23 kg are given 45mg twice a day; Those weighing 23 ~ 40kg were given 60mg twice a day; Those who weigh more than 40Kg are given 75mg twice a day. The course of treatment is 5 days, and the course of treatment for severe patients can be extended appropriately. Patients with renal insufficiency should adjust the dose according to renal function.

(2) Zanamivir: suitable for adults and adolescents over 7 years old, usage: twice a day with an interval of 12 hours; 10mg each time (inhaled twice). However, inhalants are not recommended for patients with severe illness or complications.

(3) Paramivir: the dosage for adults is 300-600 mg, 6mg/kg for newborns less than 30 days, 8mg/kg for infants 31-90 days, and 10mg/kg for children aged 91-17 years, once a day for 1-5 days, and the course of treatment for severe cases can be appropriately extended. At present, the clinical application data is limited, and the adverse reactions should be closely observed.

Ion channel M2 blockers amantadine and rimantadine are only effective for influenza A virus, but the current monitoring data show that influenza A virus is resistant to them, so it is not recommended to use them.

(4) Treatment of severe cases.

Treatment principle: actively treat the primary disease, prevent and treat complications, and provide effective organ function support.

1. In case of hypoxemia or respiratory failure, corresponding treatment measures should be given in time, including oxygen therapy or mechanical ventilation.

2. Give corresponding anti-shock treatment when combined with shock.

3. When other organ functions are damaged, give corresponding support and treatment.

4. When secondary infection occurs, give corresponding anti-infection treatment.

(5) Chinese medicine treatment

1. Treatment scheme based on syndrome differentiation for mild symptoms.

(1) Wind-heat invasion.

Main symptoms: early onset, fever or no fever, red throat discomfort, mild cough with little phlegm, and no sweat.

Tongue pulse: red tongue, thin or greasy fur, floating pulse.

Treatment: dispelling wind and relieving exterior syndrome, clearing away heat and toxic materials.

Basic prescription: Yinqiao powder combined with Sangju drink.

Honeysuckle 15g forsythia 15g mulberry leaf 10g chrysanthemum 10g

Platycodon grandiflorum 10g burdock 15g bamboo leaves 6g reed rhizome 30g

　　General Secretary of the Supreme Leader pointed out in the Party’s Report to the 20th CPC National Congress: "Promote the optimization and upgrading of goods trade, innovate the development mechanism of service trade, develop digital trade, and accelerate the construction of a trade power." With the development of global economic integration, the penetration of digital technology into trade, the rise of developing countries and the popularization of high-standard international economic and trade rules, international trade has shown a new trend of generalization, digitalization, greening, integration, service, re-globalization and security. Standing at the new starting point of the development of human society in the digital age and facing the new goal of building a socialist modern power in an all-round way, the construction of a trade power should fully understand and grasp the general trend of international trade development, make precise policies on the new track of international trade competition, and strive to enhance the innovation, competitiveness, radiation, influence and security of China’s trade.

　　First, grasp the general trend of universal development of international trade subjects, optimize the business environment of enterprises, and establish a cooperation platform for large, medium and small enterprises

　　In recent years, with the deepening of the division of global value chain and the penetration of digital technology into trade, small and medium-sized enterprises have entered the international market by participating in the division of global value chain and cross-border electronic commerce, becoming a new force in international trade, and the main body of international trade has shown a new trend of universal development.

　　An important symbol of a trading power is that trade has great radiation and influence on economic growth, people’s well-being and employment. The participation of small and medium-sized enterprises in cross-border electronic commerce and global value chains is conducive to meeting diversified international demands, encouraging enterprises to innovate, improving enterprise productivity and income, expanding employment and achieving inclusive growth. At present, private enterprises have accounted for half of China’s foreign trade import and export. In 2022, private enterprises accounted for 50.9% of the total import and export value and contributed 80.8% to foreign trade growth. Grasping the general trend of general development of trade subjects and enhancing the radiation and influence of China’s foreign trade, we should optimize the business environment of enterprises, fully implement the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Development and Growth of Private Economy, optimize the development environment of private economy, increase policy support for private economy, accelerate the cultivation of foreign trade business subjects, and strive to promote the high-quality development of private economy; It is necessary to establish a cooperation platform for large, medium and small enterprises, provide a public trading platform, an innovation platform and an industrial chain and supply chain cooperation platform for small and medium enterprises, enhance the digitalization, innovation and management capabilities of small and medium enterprises, promote small and medium enterprises to expand direct exports through cross-border e-commerce, and drive small and medium enterprises to participate in the global value chain by providing intermediate products for large enterprises, expand indirect exports and create jobs; It is necessary to strengthen international cooperation, attach great importance to SME clauses in bilateral, regional and cross-regional trade negotiations, reduce non-tariff barriers affecting the export of SMEs, and promote international cooperation and market development of SMEs.

　　Second, grasp the digital and green development trend of international trade objects, deepen international trade innovation, and promote the digital and green transformation of trade.

　　Digital technology has changed the trade object, trade mode and trade scale, purchased products and services by digital ordering and digital delivery, and promoted the development of digital trade. Since 2005, the export of digital delivery services has more than tripled, far exceeding the growth rate of trade in goods and other services. In 2019, global e-commerce sales jumped to 26.7 trillion US dollars, equivalent to 30% of the global GDP. At the same time, the higher greenhouse gas emissions caused by the production, transportation, distribution and consumption of traded products have spawned new low-carbon trade regulations such as carbon tariffs, carbon labels, carbon certification and carbon footprints, and also promoted the development of green trade with environmental products and services as trading objects. According to World Trade Organization data, as of 2018, carbon dioxide emissions related to international exports of goods and services accounted for 30% of global carbon emissions. Countries seize the new track of digital economy development, meet the new challenges of climate change, and promote sustainable economic development. Digitalization and greening of international trade objects have become the new trend of international trade development in the future.

　　General Secretary of the Supreme Leader pointed out that in today’s era, digital technology and digital economy are the opportunities for the world’s scientific and technological revolution and industrial transformation, and they are the key areas of a new round of international competition. We must seize the opportunities and seize the commanding heights of future development. Innovation is the key to building a powerful trading country, and innovation determines the competitiveness and influence of international trade. To occupy the commanding heights of international trade competition in the future, China should focus on deepening international trade innovation. To reshape the digital supply chain as the core and promote the digital transformation of trade, we should formulate trade and investment policies aimed at promoting technological innovation of enterprises and cultivate innovative subjects; Around the establishment of a new digital supply chain ecosystem, promote the digital transformation of traditional foreign trade enterprises and service enterprises; Use digital tools to promote the innovation of supervision mode, establish a digital public service platform through internet plus’s supervision, promote cross-departmental, cross-level and cross-regional collaborative supervision, and form a multi-governance system with the participation of government, platform, enterprises, industry organizations and the public. We should improve the green trade system, accelerate the green transformation, coordinate technology policy, trade policy, investment policy, environmental policy and ecological security policy, establish a green trade statistics system, a green low-carbon trade standard and certification system, and an ecological environment risk prevention mechanism to improve the green trade system; Reduce tariff and non-tariff barriers to environmental products and services and expand imports of environmental technologies and services. Strengthen international cooperation and actively participate in the negotiation of global digital trade and green trade rules. As a big digital trade country, China should strengthen multi-level international cooperation and benchmark the new rules of the World Trade Organization.Timely revision and improvement of laws that adapt to the development of digital economy and society; Accelerate the negotiation of the Comprehensive and Progressive Trans-Pacific Partnership Agreement and the Digital Economy Partnership Agreement, and expand international cooperation in the digital economy under the framework of regional and cross-regional trade agreements. As a big green trade country, China should actively set issues in multilateral trade negotiations and actively participate in the formulation of international rules, standards and management of green trade; Give priority to the inclusion of environmental provisions in bilateral and regional trade and investment negotiations and reduce tariff and non-tariff barriers; Create a professional platform for international cooperation in green trade development and promote international transactions in green technologies, products and services.

　　Third, grasp the general trend of service-oriented development of international trade structure, promote industrial integration and development, and enhance international competitiveness with digital empowerment and high-level opening up.

　　For a long time, the proportion of service trade in international trade has remained above 20%. In recent years, the development of digital technology has broken through the restriction of non-tradable services. With the liberalization of global service trade, the growth rate of service trade exceeds that of goods trade. The World Trade Organization predicts that according to the traditional trade statistics, the proportion of service trade in international trade will increase from 18% in 1995 to 25% in 2030, and it may reach 30% in 2040. According to the added value statistics, the added value of services in international trade in goods and services accounts for nearly half. Service-oriented international trade structure will become the general trend of trade development.

　　The essence of a trading power is that the industry has strong international competitiveness. Service industry and service trade are the shortcomings of China’s economic development. In 2022, service trade accounted for 12.3% of China’s total foreign trade, far below the world average (21.1%). The service trade has a long-term deficit, and the international competitiveness of most industries is weak. The management system and mechanism of service trade need to be improved urgently, which has become an obstacle to the construction of a strong trading country. To enhance the international competitiveness of China’s service trade, we should strengthen the new understanding of service value-added, promote the integrated development of service trade with modern service industry, high-end manufacturing industry and modern agriculture, accelerate the transformation and upgrading of industrial structure and enhance trade income; It is necessary to expand the service industry’s opening to the outside world, seize the development opportunity of global service trade liberalization, steadily expand the institutional opening to international economic and trade rules, improve the negative list management system of cross-border service trade, expand the opening to the outside world of telecommunications, tourism, law, vocational examinations and other service fields, and attract high-end service elements to gather in China; It is necessary to promote digital transformation, seize the new opportunity of service tradeability brought by digital globalization, accelerate the transformation of production relations adapted to the development of digital technology, promote institutional innovation around digital transformation, establish and improve the legal system, facilitation system and supervision system to promote the development of service trade, accelerate the cultivation of new digital kinetic energy of service trade, and realize the leap-forward development of service trade.

　　Fourth, grasp the general trend of the re-globalization of the international trade market structure, build the "Belt and Road" with high quality, and build a global development community.

　　After World War II, developed countries dominated the international market for a long time with their unique technological advantages, industrial advantages and monopoly advantages. Since the 1980s, developing countries, represented by China, have risen in groups. The proportion of developing economies in world output has increased from 24% to over 40%, from less than 1/3 to nearly 1/2 of the total trade in goods, and from 1/4 to 1/3 of the total trade in services. In the past decade, the contribution rate of BRICS countries to world economic growth has exceeded 50%, making it an important engine of world economic growth. General Secretary of the Supreme Leader pointed out that in today’s world, people of all countries are a community of shared destiny, and markets, funds, resources, information and talents are highly globalized. Only when the world develops can countries develop; Only when countries develop can the world develop. At present, the BRICS countries have expanded from five to eleven countries, and the African Union has joined the G20 to build the Belt and Road Initiative for ten years, which has attracted more than three-quarters of countries and 32 international organizations. The group rise of developing countries will continue to be a force to promote world economic growth. The World Trade Organization predicts that by 2040, the share of developing countries in service trade will increase from 35% to nearly 40%, and its share in total trade will exceed 50%. Unilateralism, hegemonism and protectionism cannot stop the trend of globalization, and the re-globalization of the international trade market structure is unstoppable.

　　An important symbol of a trading power is that a country’s trade has great radiation and influence on world economic growth, sustainable development and employment. Grasp the general trend of the re-globalization of the international trade market structure, build a global development community, and enhance the radiation and influence of China’s trade. We should speed up the implementation of the United Nations 2030 Agenda for Sustainable Development, practice global development initiatives, focus on key areas such as green development, new industrialization, and digital economy, strengthen cooperation in poverty alleviation, education, and health, build a global development community, and create a development pattern of balanced benefits, coordination, tolerance, win-win cooperation, and common prosperity; It is necessary to jointly build the "Belt and Road" with high quality, aim at high standards, sustainability and benefiting people’s lives, adhere to the direction of high-quality and high-standard cooperation, and take poverty alleviation, food security, education and health, development financing, green development, industrialization, digital economy and interconnection as key areas of cooperation, so that developing countries can better integrate into the international division of labor, share the fruits of economic globalization, and strive to achieve a higher level of cooperation and higher input efficiency. It is necessary to strengthen South-South cooperation, give full play to the role of the Forum on China-Africa Cooperation, an important platform for South-South cooperation, implement the outcome of the 2023 China-Africa Leaders’ Dialogue, practice the Initiative of Supporting Africa’s Industrialization, steadily implement the China Plan for Helping Africa’s Agricultural Modernization and the China-Africa Cooperation Plan for Talent Training, promote Africa’s integration and modernization, and realize the common prosperity and sustainable development of the Chinese and African people.

　　5. Grasp the general trend of universal development of high-standard international economic and trade rules, and comprehensively deepen reform and expand opening up to high-standard international economic and trade rules.

　　Regional and cross-regional negotiations such as the US-Mexico-Canada Agreement, the Comprehensive and Progressive Trans-Pacific Partnership Agreement and the Regional Comprehensive Economic Partnership Agreement have reconstructed high-standard international economic and trade rules, triggering the domestication of international economic and trade rules; The negative list management of service trade has entered the trans-regional partnership agreements such as the Comprehensive and Progressive Trans-Pacific Partnership Agreement and the Regional Comprehensive Economic Partnership Agreement from the regional trade agreement of the US-Mexico-Canada Agreement, which has led to the trans-regional economic and trade rules. The Regional Comprehensive Economic Partnership Agreement is by far the largest free trade agreement in the world, with its total population, economic scale and total trade volume accounting for 1/3 of the global total. The Comprehensive and Progressive Trans-Pacific Partnership Agreement involves a population of more than 500 million. After Britain’s accession, the trade scale exceeds that of the Regional Comprehensive Economic Partnership Agreement, affecting Eurasia, and the trend of universality of high-standard international economic and trade rules is taking shape.

　　General Secretary of the Supreme Leader pointed out that we should focus on promoting high-level opening to the outside world, continue to comprehensively deepen reform, and steadily expand institutional opening such as rules, regulations, management and standards. International economic and trade rules determine the content and scale of trade, the competitiveness, radiation and influence of trade and the future of trade. In order to conform to the general trend of the universality of contemporary high-standard international economic and trade rules and enhance the competitiveness, radiation and influence of China’s foreign trade, it is necessary to raise the standard international economic and trade rules, promote reform by opening up to the outside world, seize the development opportunity of domestication of international economic and trade rules, deepen reform in an all-round way, and give play to the driving force of trade on domestic economic reform, the traction of economic growth and the radiation of sustainable development; We should participate in the negotiation of high-standard international economic and trade rules, promote cooperation through openness, enhance the international competitiveness of China’s foreign trade in a wider range, in a wider field and in a deeper level of international cooperation, give play to the traction of China’s economy on the world economy in the linkage with the global economy, and enhance the radiation and influence of China’s foreign trade.

　　Six, grasp the development trend of international trade environment security, strengthen international cooperation, establish and improve the international trade security system.

　　The impact of external shocks such as Sino-US trade friction, COVID-19 epidemic and Ukrainian crisis on international trade has aroused great concern of the international community on trade security. In order to maintain the global hegemonic position and ensure economic security, the United States, based on western democratic values, forced the implementation of friendly shore outsourcing, offshore outsourcing, decoupling and breaking the chain, and reshaped the global value chain; The European Commission issued the European Economic Security Strategy, and formulated a policy framework to safeguard the EU’s economic security, to guard against supply chain and energy security risks, key infrastructure and network security risks, and technology leakage risks. Japan adopted the Law on Promoting Economic Security to strengthen the security of key products and important materials supply chain and strengthen the review of key infrastructure. Industrial chain supply chain security, data security, food security, energy security, science and technology security, financial security, biological security, the unprecedented changes in a hundred years have accelerated the evolution of the new trade environment, ensuring trade security has become the general trend of global trade development.

　　The General Secretary of the Supreme Leader pointed out that we should make overall plans for development and security, pay equal attention to development and security, and realize the benign interaction between high-quality development and high-level security. Trade security is the foundation and premise of building a strong trading country, and a strong trading country must first be safe. To cope with the changes in the external trade security environment and comprehensively enhance the security of China’s foreign trade, we must accelerate the construction of a new development pattern, realize the security and controllability of key industries, infrastructure, strategic resources, major science and technology, and firmly grasp the strategic initiative of coordinating national development and security in our own hands; It is necessary to improve the international trade security system, strengthen the trade security risk early warning, prevention and control mechanism and capacity building, improve the modern export control system, industrial injury early warning system and foreign investment national security review system, strengthen the protection of overseas interests and risk early warning, safe and efficient trade risk management, and establish a trade security governance system with supply chain security as the core; It is necessary to strengthen international cooperation, give full play to the important role of international trade in maintaining peace and security, safeguard the authority of the rules-based multilateral trading system, strengthen regional and cross-regional cooperation, resist the risks that may be brought about by trade concentration through trade diversification, and promote world peace and development through open cooperation and interconnection.

On the 25 th, the number of citizens who went to the fever clinic of Hankou Hospital for treatment and examination was greatly reduced compared with the previous days. The number of people waiting in line was small and orderly. Changjiang Daily reporter Ke Aesthetics photo

　　On January 23, Wuhan announced that the city’s urban buses, subways, ships and long-distance passenger transport were suspended;

　　On January 25, Wuhan City closed the river-crossing tunnel, and carried out temperature detection and control on the traffic of the river-crossing bridges in the Third Ring Road and within the Third Ring Road;

　　… …

　　All these initiatives point to one key word: isolation. Avoid cross-infection through isolation and avoid the spread of the epidemic.

　　However, in this extraordinary period, many citizens went to the hospital because of panic and headache, and the fever clinic was full of people. Fortunately, on the 25th, after Wuhan implemented the city-wide investigation of fever patients and classified arrangements for fever patients, the fever clinics in some hospitals finally began to "cool down". However, are you relieved when you get home? In the face of the epidemic, will home isolation work? On the 25th, experts who fought in the front line and patients who experienced it all advised that common flu may cross-infect when they get together and run to the hospital.

　　Running to the hospital when you have a fever may be infected in a muddle.

　　It is understood that last year, the number of influenza patients diagnosed in Wuhan in January and February alone exceeded 50,000, and the number of common cold patients exceeded 100,000. This year, there is a global influenza outbreak, and there are more patients with common cold and flu.

　　Attending surgeon Sheng Shi, a vascular specialist in the Union Hospital affiliated to Tongji Medical College, Huazhong University of Science and Technology, believes that the current disease is one point, while the panic is ten. He has to rumor on WeChat more than 20 times a day. "If you have a fever and are uncomfortable, it doesn’t mean that you are infected with new pneumonia."

　　"Every time I have a fever, do I go to the hospital?" Sheng Shi asked questions to netizens on the Internet in the name of a doctor. After all, such people are definitely a minority.

　　Wrapped in panic, what happened in the fever clinic is probably to take your temperature, and there are 100 people waiting in line in front; Check a blood, look at the number of lymphocytes and white blood cells, and there are another 100 people; Do a CT scan to see if there is ground-glass degeneration in both lungs, and there are another hundred people … … In this process, it is likely that you will really be infected in a daze. Sheng Shi appealed that if you don’t feel uncomfortable, just rest at home honestly and stop panicking for medical treatment.

　　"Under the age of 40, patients with new pneumonia who have no high fever (> 38.5 degrees) or active dyspnea can be completely isolated at home without panic!" On the afternoon of 25th, when Changjiang Daily reporter contacted Du Ronghui, the leader of the expert group on prevention and treatment of new pneumonia in pulmonary hospital, her attitude was very clear.

　　Dr. Du Ronghui said that at present, severe patients with new pneumonia are concentrated in elderly patients over 65 years old with diabetes and basic diseases such as kidney, liver, cardiovascular and cerebrovascular diseases. Their condition develops rapidly and often develops into severe cases within one or two days. Therefore, these patients should go to the fever clinic for medical treatment as soon as they have symptoms.

　　Suspected patients are isolated at home for ten days, and the situation is getting better.

　　"Oh, Lao Liu, who played cards together, had a fever. He should have been infected by another colleague named Wang." On the evening of January 13th, the mother mentioned this in her phone call, and Ms. Huang (pseudonym) who lives in Panlongcheng still felt lucky.

　　On 14th, Lao Liu was hospitalized with a high fever of 39℃, and Huang Mu also felt uncomfortable. Until 16th, Huang Mu’s body temperature reached 37.8℃.

　　Since 17th, the situation has become serious. Huang Mu has been drinking water, but her mouth is still dry. She has a persistent high fever, poor appetite and insomnia for several days. The next day, Huang Mu had a CT scan of her lungs, showing the shadow of "ground glass" on both lungs. She was suspected of new pneumonia and needed to be hospitalized, but there was no bed. Ms. Huang accompanied her mother to several hospitals, all of which were overcrowded.

　　In order to save herself, Ms. Huang consulted a doctor through her relationship. The doctor comforted her. At present, the treatment of this disease mainly depends on self-resistance. Home treatment is not necessarily a bad thing. The environment and food are better. There are many critically ill patients in the hospital, which increases the risk of cross-infection.

　　Ms. Huang’s heart is a lot more solid. Since the status quo is already so, it is better to rest and nourish at home with peace of mind. After coming back from the hospital, Huang mother washed her hair, bathed and washed clothes, and cleaned up the hygiene inside and out. After such a busy time, she actually felt a lot lighter. To help her mother sleep, Ms. Huang also let her take sleeping pills. With the improvement of sleep quality, Huang Mu’s appetite has gradually recovered. Although she is still closely observing, she is getting better every day. From the emotional collapse due to not being admitted to the hospital, Ms. Huang now believes that sleep and nutrition are very important, and we must strengthen our own resistance; More importantly, we must pay attention to isolation from our families and avoid cross-infection.

　　Home isolation is to help patients clarify the steps of seeing a doctor

　　Home isolation does not mean no treatment, but triage through port moving forward, which helps patients to clarify the steps of medical treatment and avoid cross-infection so that the epidemic will not spread.

　　Zhao Su, chairman of the Respiratory Branch of Wuhan Medical Association, winner of the China Doctor Award and chief physician of the Department of Respiratory and Critical Care Medicine of central hospital of wuhan, worked in the SARS isolation ward for 36 days during the SARS period in 2003. With the outbreak of new pneumonia, he has been on the front line, wearing protective clothing every day to go to the isolation ward for rounds of consultation, and he also participated in the formulation of technical specifications for community prevention and treatment of new pneumonia in Wuhan as an expert.

　　Zhao Su introduced that fever is a symptom of many diseases. Just starting to have a fever, don’t panic. Observe at home for a day or two. Some slight fever may be a cold, temperature fluctuation, and some may be caused by tension, so it needs to be observed. First go to the community for fever screening. It is understood that in the technical operation specifications for community hospitals, patients with fever are required to be screened first: patients with body temperature over 37.5℃ and fever for more than two days without flu-like symptoms (stuffy nose, runny nose and sneezing) should be sent to the fever clinic for further screening.

　　"Community screening can find patients early and reduce cross-infection caused by patients rushing to fever clinics." Director Zhao Su said that those who need to be hospitalized do not need to be hospitalized for minor illnesses or go back to community concentration points for isolation treatment or home isolation treatment.

　　Taking good care of your health will definitely overcome the new pneumonia.

　　On January 19th, Zhou Ning, deputy chief physician and associate professor of the Department of Cardiology, tongji hospital, affiliated to Tongji Medical College, Huazhong University of Science and Technology, underwent an operation, and successively developed dizziness, fatigue, nausea, diarrhea, chills and other symptoms. His temperature was 38.9℃, and he was suspected to be infected. On the 21st, Zhou Ning cut off all close contact with his parents that day. Wear a mask when sleeping, close the door and monitor your body temperature … … By the 24th, the body temperature was 36.8℃ and returned to normal.

　　Zhou Ning’s self-reported experience has more than 11 million readings on the Internet. Many people question whether the new pneumonia has been included in Class B infectious diseases, Class A management, home isolation treatment or hospitalization. On the 25th, Zhou Ning said in an interview with Changjiang Daily that home isolation, whether it is diet or accommodation, is better than hospital. As long as we eliminate fear and remain optimistic, it will be very helpful to reshape our immune system.

　　Viral infections are self-limited. As long as they don’t induce substantial organ damage, such as viral pneumonia, they can be defeated by keeping healthy and waiting for their own immune system to grow and counterattack.

　　The epidemic situation is fierce, and rushing to the hospital blindly will not only increase the risk of cross-infection, but also make it unlikely to be admitted to hospital. Because the current beds are mainly for patients who are diagnosed or seriously ill.

　　According to the emergency guidelines previously issued by the World Health Organization, when hospitalization conditions are not allowed or safe and medical resources are insufficient, alternative isolation methods including home isolation should be considered for mild patients suspected of infection.

　　At the same time, Zhou Ning believes that home isolation has put forward higher requirements for community management and self-supervision. For infectious diseases, even mild ones are contagious. On the day he found symptoms, he entered the house wearing a mask and kept a safe distance of one meter from others.
