Keyword 1: discuss and build together

In the renovation of old residential areas in Chongqing, we always adhere to the people-centered development idea, adhere to the concept of "creating a beautiful environment and a happy life together", fully respect the wishes of residents, and realize joint construction and democratic decision-making. Although the actual work will face problems such as low participation of the masses and imperfect long-term management mechanism, doing mass work well and fully mobilizing the enthusiasm of the masses is still the key to implementing the transformation, joint construction and sharing mechanism of old communities.

In the renovation of old residential areas, cadres at all levels should go into the residential areas and go to the residents to understand the problems that they most want to solve that affect their daily lives. Chongqing gives full play to the leading role and organization and coordination function of grass-roots party organizations, actively builds a platform for communication, consultation and discussion, and ensures that residents in old residential areas can participate in the whole process of renovation. Through organizing various forms of democratic consultation, we can listen to residents’ demands and solve doubts and doubts, and jointly negotiate the content standards, investment costs, fund raising and long-term management of old residential areas, and implement the "menu selection" model.

Before the implementation of the renovation, give full play to the advantages of street offices, community neighborhood committees and grass-roots party organizations in publicity and education, organization and mobilization and mass work, actively promote planners, architects and engineers to enter the community, guide residents to participate in the renovation, and promote the formation of a consensus on the renovation of old communities. In the process of transformation, we will establish a co-management and co-construction system led by grassroots party organizations and residents’ self-governing organizations, give full play to residents’ initiative, and guide residents to participate in transformation in different forms. After the renovation is completed, a joint meeting system of community management with the participation of community neighborhood committees, owners’ committees, property service enterprises and other multi-subjects will be established to jointly plan and maintain the management methods of the renovation achievements of old communities and realize long-term management.

Keyword 2: Menu selection

After practical exploration, Chongqing has initially established the content system of the renovation of old residential areas from the city to the district, and standardized it through supporting documents and guidelines.

Chongqing Municipal Commission of Housing and Urban-Rural Development, Municipal Development and Reform Commission and Municipal Finance Bureau jointly issued the Implementation Plan for the Renovation and Upgrading of Old Residential Areas in the Main City of Chongqing (hereinafter referred to as the "Plan"), which clarified the overall requirements, implementation contents and standards, implementation procedures and safeguard measures for the renovation of old residential areas in the main city. The Plan refines the renovation of old residential areas according to two categories: comprehensive renovation and management upgrading, and initially determines the comprehensive renovation contents and guiding standards of five major items and 39 minor items, namely, infrastructure renovation, supporting service facilities construction and renovation, housing public area renovation, renovation and upgrading of adjacent infrastructure related to residential areas, and overall improvement of basic public service facilities, and determines 25 minor items in six major items, namely, environmental sanitation, housing management and maintenance, security and vehicle management, greening management, public facilities management and property service supervision. In the process of renovation, residents can completely change the previous government’s "all-in-one-bag" mode into residents’ "menu selection" mode according to their daily needs and the actual situation of the community, and fundamentally solve a series of livelihood problems closely related to residents’ daily life.

Keyword 3: Two-pronged approach

The renovation of old residential areas implemented in Chongqing this time mainly focuses on residential areas that were built before 2000, with backward public facilities, affecting residents’ basic life and strong residents’ willingness to renovate, and continue to be renovated and upgraded in accordance with the requirements of the Plan.

Comprehensive renovation refers to the overall utilization of renovation, facility renovation, functional renovation, comprehensive renovation and other ways to implement the organic renewal of old residential areas. In addition to classification, comprehensive renovation can be divided into basic items, additional items and overall implementation items according to the nature of the project. Among them, the basic item focuses on solving the basic problem of housing; Add items to focus on improving the quality of living and reflect the orientation of urban upgrading according to local conditions; Coordinate the implementation of the project, focus on improving basic public service facilities, optimize resource allocation, and promote the improvement of community governance.

Management promotion refers to standardizing community management by introducing property service enterprises, residents’ autonomy and setting up community property service centers to build a safe, clean, tidy and orderly atmosphere.

The implementation of comprehensive transformation of old residential areas, to follow up the management improvement, consolidate the transformation results, and promote long-term maintenance; The old residential areas that have been upgraded in management will be comprehensively transformed when conditions are ripe, so as to alleviate the pressure of centralized transformation and realize the unity of positive actions and capabilities.

Keyword 4: Community service

The renovation of old residential areas in Chongqing is not only limited to the renovation of buildings and environment, but also focuses on related facilities and combines the development of community services with the renovation of old residential areas. Community service must keep pace with the development of the new era, adhere to the people-centered, improve the service quality and improve the service content according to the actual needs of residents. At present, the level of community service in old communities in Chongqing is generally low, and the service items are single. There is a big gap between old communities and new communities in terms of community care for the aged, services for the disabled, health care, culture and sports, and convenience facilities.

In order to further improve the quality of community services and expand the scope of community services in old residential areas, Chongqing has focused on meeting the daily material and cultural needs of residents and improving the living quality of residents in the process of renovation, integrating street comprehensive service centers, community convenience service homes, community pension and other contents into the implementation plan, and guiding police offices, day care centers, health service stations and community cultural rooms through new construction, renovation, purchase, project matching and integration and sharing. While doing a good job of "one-stop" service and "one-stop" service, neighborhood offices and community neighborhood committees cooperate with departments at all levels and relevant units to continuously integrate social resources, contribute to improving the level of community service, and make old communities look good and live well.

The renovation of old residential areas in Chongqing summed up four key words, namely "co-construction, menu selection, two-pronged approach and community service", and achieved good results. Take Changshiyuan Community in Jiulongpo District, which was built in 1994 as an example. There are 7 buildings and 224 households in the community, with a construction area of 25,000 square meters. It belongs to the resettlement housing community with no property service and managed by the community. Due to various reasons, there are many problems in Changshiyuan Community, such as prominent security risks, serious house damage, lack of supporting facilities, and chaotic management order. Through the renovation and upgrading of old residential areas, projects such as fire fighting facilities renovation, drainage pipe network replacement, pipeline regulation, illegal construction and demolition, road paving, landscape building, etc. will be accurately implemented, and convenience service facilities such as intelligent parking management system, community cultural corridor and fitness equipment will be added. The environment of Changshiyuan residential area has been significantly improved, the living facilities are basically complete, and residents’ sense of acquisition, happiness and security has been significantly improved. Residents who moved out in the early stage moved back one after another to enjoy the fruits of this transformation together.

　　Wearing a uniform, he greeted the passengers with a smile and showed them the way. Not only that, he can also communicate with foreign tourists in fluent English. He is Zhang Hua, the security guard at Zhonghua Gate Station of Nanjing Metro. Recently, a video shot by a netizen of Uncle Zhang Hua guiding foreign tourists in fluent English made Uncle Zhang a "online celebrity". The netizen even felt: "Uncle English is so awesome, I thought it was a bronze, but it turned out to be a king!"

　　The pictures in this article are all dragon and tiger network pictures. "I learned English by myself when I was just working in my twenties, and I also took the national self-study exam." On the afternoon of July 18th, the reporter met this "online celebrity" uncle at Zhonghua Gate subway station. Uncle Zhang told the reporter with a smile that he liked English very much when he was in high school. Later, he met many foreign friends at work and the company had a lot of English materials, so he had the idea of learning English by himself. "Actually, I didn’t use a lot of English in my previous job. I didn’t expect to be a subway security guard after retirement, and I was surprised to use English in this position."

　　Uncle Zhang said that before foreign passengers asked for directions in blunt Chinese, he communicated with each other in English. "Foreign passengers were surprised and thought that a small security guard could speak English so well." Before being transferred to Zhonghua Gate subway station, Uncle Zhang worked as a security guard in Xuanwu Gate subway. At that time, he met a group of international students from Beijing who wanted to visit Xuanwu Lake Park, but didn’t know which exit to take. "I told them how to get there in English at that time. They were very happy and gave them a thumbs-up before leaving." Talking about this impressive guide, Uncle Zhang smiled happily. "I feel that I have won glory for Nanjing."

　　(The original title is: "The security uncle of the subway is a real cow: fluent English is praised for guiding foreign passengers")

The original Singularity Cake Singularity Network is included in the collection # 62 Intestinal Microbes # 57 Cardiovascular Diseases.

* For medical professionals only.

It’s summer. Have you arranged all the beer skewers and juice in little seafood? Singularity cake every time I watch this kind of food electronic mustard tuber, the barrage will float past the "gout package!" Hmm … Everyone has a high awareness of health!

Foods such as beer, seafood and animal offal are rich in purines, and some purines, such as xanthine, hypoxanthine and uric acid, the final metabolites of purines, are considered as uremic toxins (wastes that patients with impaired renal function cannot metabolize normally) [1], which are related to some symptoms of chronic kidney disease [2].

It is also a typical symptom of gout that uric acid can not be metabolized normally, resulting in the formation of pro-inflammatory crystals deposited on joints. However, some studies have found that uric acid concentration within the solubility range can also promote atherosclerosis through AMPK pathway-mediated inflammation [3]. Isn’t the kidney working hard enough? However, intestinal microbes will shoot!

Recently, the research team at the University of Wisconsin-Madison found that intestinal microorganisms can affect the progression of atherosclerosis by regulating the level of uric acid circulation. They identified intestinal microorganisms that use purines such as uric acid as carbon and energy sources in anaerobic environment, as well as gene clusters encoding key steps of purine degradation. This is a potential new way for intestinal microorganisms to affect health, which may provide a new way for treating gout or preventing cardiovascular diseases. The research results were published in Cell, Host and Microorganism [4].

Previous studies have shown that the atherosclerosis burden of more than 100 inbred mice in the Hybrid Mouse Diversity Group (HMDP) is very different, and the composition of intestinal flora is also obviously different [5,6].

In this study, the researchers selected four kinds of HMDP, two of which showed obvious atherosclerosis (experimental group) and two of which showed almost no signs of disease (control group), transplanted their flora to aseptic APOE knockout mice (which could spontaneously form hypercholesterolemia and atherosclerosis) and fed them with a diet supplemented with 0.2% cholesterol for 8 weeks.

Compared with the control group, the pathological changes in the experimental group are obvious. Traditional cardiovascular risk factors such as body weight and cholesterol intake, as well as intestinal microbial metabolites lipopolysaccharide, trimethylamine -N- oxide (TMAO) and short-chain fatty acids can’t explain this difference.

Macrogenome analysis identified 1649 functional features and 52 bacterial taxonomic features, and correlation analysis identified several bacterial functions related to atherosclerosis load, including those related to purine production and transformation. Among the 682 metabolites in mouse plasma, purine metabolites, including xanthine, xanthine nucleoside, inosine and uric acid, are positively correlated with the size of atherosclerotic plaque.

Correlation between xanthine, xanthine nucleoside, uric acid and inosine and atherosclerotic plaque size

In the cohort of human volunteers, there is a significant positive correlation between coronary artery calcification (CAC) score and uric acid level, and several taxonomic units in Clostridium have a negative correlation with uric acid level, which may affect uric acid level.

Compared with conventional mice, most purine levels in cecum/feces of sterile mice decreased, and only uric acid and allantoin levels increased. Similarly, the level of uric acid in plasma of sterile mice also increased significantly. Therefore, intestinal microorganisms may be able to regulate the level of purine in intestine and whole body. This strengthened the researchers’ determination to isolate purine-degrading bacteria in the intestine.

Intestine is the key organ of purine homeostasis. Dietary purine is absorbed in the intestine, and intestinal microorganisms produce and recover purine needed for its anabolism. About 30% uric acid produced by body metabolism will be secreted into the intestine.

The researchers tried to enrich anaerobic bacteria on the culture medium with uric acid as the main source of carbon and energy by using human feces samples, and obtained several bacteria from Firmicutes and Proteobacteria, which were identified as Enterocloster bolteae and Escherichia coli by 16S rRNA sequencing. The model strain ATCC BAA-613 of Enterocloster bolteae was cultured in a medium supplemented with 12mg uric acid. 10ml of strain culture degraded 49.6μmol of substrate within 24 hours, and produced 106.9μmol of acetate.

Based on the success of this small-scale attempt, the researchers expanded the search for intestinal microorganisms with purine degradation ability, and identified 34 kinds of bacteria from 6 phyla by the same method. The purine utilization ability of different bacteria is different. For example, Escherichia coli MS200-1 and I-11 have stronger uric acid utilization ability than Escherichia coli K12. Allantoin can support the growth of Enterocloster bolteae and Escherichia coli, but it cannot support the growth of Clostridium difficile or Edwardsiella tarda.

Representatives of 34 kinds of bacteria

By comparing the conserved chromosome regions of these intestinal microorganisms, the researchers found that five genes (dpaL, hydA, ssnA, ygeY and xdhD) were conserved. Compared with the sterile mice with non-purine degrading flora and the sterile mice with conserved gene deletion mutant flora, the plasma uric acid level of the mice with wild-type strains was significantly lower. There was a negative correlation between the level of purine-related metabolites in cecum and the abundance of five genes in APOE knockout sterile mice. This shows that these genes and their encoded intestinal bacteria have the ability to regulate uric acid homeostasis in vivo.

Identification of conserved genes

Generally speaking, this study found a previously neglected factor affecting uric acid circulation level-intestinal microorganisms and the corresponding key genes. In the future, more research is needed to answer the effects of aerobic and anaerobic purine consumption pathways on purine and intestinal microecology, as well as atherosclerosis and other health conditions.

　　In the investigation of power exchange, we can see that among the options that think the biggest problem of power exchange is what, 36.95% people choose the quality assurance problem as the most concerned issue. During the investigation and interview, it is generally believed that the battery replaced by your own car will be an old battery or a battery with signs of attenuation. It will affect the cruising range or cause vehicle damage. On the issues of quality assurance and power exchange safety, this paper makes an all-round analysis in the chapter of quality assurance and power exchange safety in "RTS for Power Exchange" specially planned by Sina Automobile.

　　The state has issued relevant testing and construction standards for batteries, charging piles and stations of new energy vehicles.

　　The national testing standards for new energy electric vehicles include complete vehicles, parts, interfaces and facilities. The power batteries of new energy electric vehicles belong to the category of spare parts. For the testing of power batteries for new energy electric vehicles, the General Administration of Quality Supervision, Inspection and Quarantine of China and the National Standardization Administration of China jointly issued six national standards on May 15th, 2015, which were fully implemented in 2016.

　　There is no clear policy on the specific index range of battery quality assurance and attenuation. The battery core, connection board and circuit board are basically agreed according to the warranty of the car company. For example, BYD is a lifetime battery warranty; Roewe guarantees the battery attenuation; Beiqi New Energy has a lifetime warranty for some models’ batteries, and the batteries enjoy a trade-in discount; Jianghuai, Emgrand and Changan guarantee the battery for at least five years; Qichen reduces the repurchase fee by 10,000 for every 10% attenuation of the battery; The 8-year warranty of imported brand Tesla’s battery components is unlimited mileage.

　　However, there is no clear numerical value for reference. If consumers have doubts about the battery life of the purchased vehicle, the battery attenuation range will be decided by the manufacturer. A brand needs to test the battery in the store and form a report, and then the manufacturer will decide whether the vehicle is in normal attenuation, and the battery is divided into "normal attenuation" and "abnormal attenuation", and "normal attenuation" is not covered by the lifetime warranty.

　　According to the fact that the battery is shared with the battery, the battery is not actually a private part. In fact, it also reduces the time for rapid battery decay. According to the charging requirements of the battery in the power exchange station, the battery is uniformly charged in the constant temperature and humidity environment of the power exchange station by alternating current slow charging, so that the service life is prolonged and the loss is low. Moreover, people, batteries and cars are safer because of the operation of special personnel and robots. The battery pack can be guaranteed for 600,000 kilometers. The direct charging mode of electric vehicles, especially fast charging, is difficult to achieve attenuation of less than 20% in 8 years and 150 thousand kilometers.

　　Many consumers are puzzled, will there be old batteries installed in their cars, which will reduce the cruising range or cause problems in the vehicles? In fact, this problem, the power station is more worried than consumers about battery problems, or the situation of old batteries. According to Wei Lai Li Bin’s explanation, after each battery with low battery capacity is replaced in the power station, the battery detection system of the power station will be started to judge the "survival" state of this battery, and whether to save and continue to use this battery is equivalent to a "physical examination" of the battery every time it is replaced. The system will "take off the shelf" the battery that is not suitable for loading into the car, which is convenient for future use as an energy-eating battery. In this process, BAIC New Energy is also in use. Therefore, the battery in the battery replacement can be more "healthy" than in your own car.　　

　　In terms of power supply, the Specification for Power Supply System of Electric Vehicle Charging and Replacing Power Station issued by State Grid Corporation in August 2017 clearly stated that when enterprises build high/low voltage charging and replacing power stations, they need to build according to the approved design specifications for power distribution and transformation, and do a good job in the installation and operation of protective devices and related power supply design requirements. According to the scale and application situation of charging and replacing power stations, the standards of different load levels are constructed. According to the requirements, there are seven power supply design standards, including power supply requirements, power quality indicators, safety requirements, power metering, power supply monitoring functions and signs.

　　After consulting a large number of materials, it is found that there is only one technical specification for the construction of power exchange station, which is the Technical Specification for the Operation Management System of Intelligent Charging and Switching Service Network for Electric Vehicles Based on the Internet of Things issued by State Grid Corporation in 2011, and the development plan of electric vehicles, the development plan of charging service network for electric vehicles in the Twelfth Five-Year Plan of State Grid Corporation, is also released. At that time, the commercial operation mode of "mainly replacing electricity, supplemented by plug-in, centralized charging and unified distribution" was put forward, and the operation management system of intelligent charging and replacing service network was developed in a unified way, and the demonstration operation of charging and replacing network and battery leasing pilot were carried out. Since then, the relevant departments have failed to issue other specifications and standards for the field of electric vehicle replacement with rapid technological innovation. Until May 2012, the Development Plan of Energy-saving and New Energy Vehicles (2012-2020) issued by the State Council proposed to explore new energy vehicles, battery leasing, charging and replacing services and other business models, and encouraged the establishment of independent charging and replacing enterprises to gradually realize the marketization and socialization of the construction and management of charging and replacing facilities.

　　This development plan will push the field of power exchange to the market-oriented experimental period, that is, during this period, in 2016, the electric bus founded Aodong New Energy and cooperated with BAIC New Energy to promote electric taxis. Up to now, Aodong has built 81 power exchange stations in Beijing. By the end of 2017, AUTO will build and operate 130-150 power stations nationwide, which can serve 13,000-15,000 electric vehicles.

　　By summing up and drawing lessons from the failure of international power exchange stations, domestic power exchange stations have improved a lot in technology, such as high-power connectors. In 2016, this technology was applied in the cooperation between Aodong New Energy and BAIC New Energy to promote the replacement of electric taxis. In the 81 power exchange stations built in Beijing, Aodong New Energy adopts the high-voltage electrical connection technology with plane spring coil to solve the problem of high-power connection and ensure the follow-up when the car bumps.

　　Weilai is more advanced. In order to solve the subtle problems in power exchange and ensure the unification of each power exchange, Weilai has specially developed a power exchange system, which covers an area of only three parking spaces and can replace the battery of an ES8 in just three minutes. This system is highly technical and has more than 300 patents.

　　However, although the technology has been improved, the power station is still limited by the weather, or it cannot be replaced or has minor defects. In the few days when the author made an unannounced visit, he caught up with the heavy rain in Beijing. Due to the accumulated water, the gap between Weilai Power Station and the ground was very small, and it was easy to cause the accumulated water to flood in in the case of heavy rain. Although Beiqi New Energy’s power exchange station is relatively high off the ground, the vehicles washed by rain water enter the power exchange station with rain water, which is easy to cause the sensor to get wet, resulting in the robot arm not being able to accurately aim at the battery shell screws, and the power exchange failed in the interview. Finally, after the position is determined by the naked eye of the staff, it is replaced in place again.

　　Through analysis, we know that changing the power station can delay the battery decay time and greatly improve the battery life. In addition, through the relevant national codes and standards, the standards of power station construction are also being improved. As far as the former Better Place and Tesla power stations are concerned, the technical level of power station in China has reached the leading position. Looking at the whole power exchange industry from the perspective of the safety of power exchange stations, consumers can be completely at ease. In the next article of "RTS for Power Exchange" specially planned by Sina Auto, we will analyze the parts that need to be improved from the operation of the power exchange station.

　　Xinhua News Agency, Beijing, November 2 (Reporter Pan Jie) Faced with the impact of the COVID-19 epidemic, how can the upstream and downstream supply chains in different areas of APEC economies achieve cross-border coordination and promote economic recovery and growth? At the APEC Forum on Strengthening Supply Chain Resilience and Promoting Economic Recovery held on the 2nd, many guests believed that we should seize the development opportunities brought by the digital economy and strengthen cooperation in e-commerce and digital trade development, so as to improve the resilience and vitality of the industrial chain and promote economic recovery and growth.

　　"The epidemic has made us pay more attention to digital transformation, and also let us see the important role of digitalization in promoting trade facilitation." Rebecca Maria, Executive Director of APEC Secretariat, said that APEC member governments are expected to further strengthen investment in digitalization and innovation, deepen exchanges and cooperation, further enhance the level of trade liberalization and facilitation, and promote the continuous strengthening of supply chain resilience.

　　Lu Mei, a senior APEC official in China and deputy director of the International Economic Department of the Ministry of Foreign Affairs of China, believes that developing the digital economy is a key opportunity to grasp the new round of scientific and technological revolution and industrial transformation. It is necessary to keep up with the development trend of digital economy and promote the digital transformation and upgrading of traditional enterprises; Comprehensively and balancedly implement the APEC Internet and digital economy roadmap, and strengthen the interconnection in the digital age; Strengthen digital capacity building, focus on cooperation among women, small and medium-sized enterprises and agriculture, and bridge the digital divide.

Lin Nianxiu, deputy director of the National Development and Reform Commission, said.

　　Zhang Shaogang, vice president of the China Council for the Promotion of International Trade, said that the business community is a constructive force to enhance the resilience of the industrial chain and promote the recovery and growth of the world economy. It should seize the development opportunity of the digital economy, encourage the development and cooperation of e-commerce and digital trade, strengthen the cooperation of digital platforms in the supply chain, and enhance the intelligence level of the industrial chain supply chain.

　　The forum was hosted by the National Development and Reform Commission. Representatives of the APEC Secretariat and Economic Commission, government officials of member economies, representatives of embassies and consulates, experts and scholars, entrepreneurs and other Chinese and foreign guests conducted in-depth exchanges and discussions on topics such as "maintaining the stable operation of the supply chain, supporting free and open trade", "smoothing the cross-border circulation of people and goods, strengthening the supply chain security system" and "applying digital technology and green technology to enhance the resilience of the supply chain".

　　Digital trade has broken the time and space restrictions of traditional trade, and has had a profound impact on the mode, structure and rules of global trade, and has become an important force leading the growth of global trade.

　　Single-hole endoscopic surgery robots, driverless cars, live e-commerce figures, etc. attract many viewers to stop; Cambodian longan has expanded its sales by using China e-commerce channels; Ethiopian coffee beans are transported to China through overseas warehouses, processed and packaged into ear-hanging coffee, and then sold by the live broadcast platform … … At the second Global Digital Trade Expo held not long ago, some new formats and models of digital trade were eye-catching, showing the vigorous vitality of digital trade.

　　When the Chairman of the Supreme Leader sent a congratulatory letter to the Second Global Digital Trade Expo, he pointed out: "At present, global digital trade is booming and has become a new bright spot in international trade." More than 800 domestic and foreign digital trading enterprises participated in this fair, and more than 100 "digital new products" made their debut, and 32 projects were signed on site, with a total contracted amount of 155.85 billion yuan. Digital Trade Fair is a national, international and professional exhibition with the theme of digital trade, which builds a platform for global digital trade cooperation and sharing digital trade dividends, and shows more possibilities brought by the development of digital economy.

　　With the rapid development of digital technology, digital trade is becoming a new trend of international trade development and a new growth point in the future. In recent years, China has attached great importance to the development of digital trade and achieved good results, and its international popularity and influence in the field of digital trade have been continuously improved. According to the China Digital Trade Development Report 2022 released by the Ministry of Commerce, in 2022, the import and export volume of digitally deliverable services in China was US$ 372.71 billion, up 3.4% year-on-year, and the scale reached a new record high. The import and export volume of cross-border e-commerce reached 2.11 trillion yuan, a year-on-year increase of 9.8%. This shows that China’s digital trade has great development potential. Conforming to the development trend of digital economy, strengthening international cooperation and jointly promoting global digital trade exchange and digital economy development will not only help promote the high-quality development of China’s economy, but also inject new momentum into international economic and trade cooperation.

　　Under the background of the accelerated evolution of the world in the past century and the counter-current of economic globalization, developing digital trade is of great significance for creating new possibilities of international trade and maintaining economic globalization. Digital trade has broken the time and space restrictions of traditional trade, and has had a profound impact on the mode, structure and rules of global trade, and has become an important force leading the growth of global trade. Online platform and digital technology enable service providers to directly face the global market, opening up new trade space. For example, Beijing relies on Zhongguancun Software Park National Digital Service Export Base to build a "digital trade port" and promote international cooperation in digital trade. China has a huge amount of data resources and rich application scenarios of digital trade, and the development of digital trade has unique advantages. It is necessary to further optimize the network layout, improve the level of digital governance, and promote the high-quality development of digital trade.

　　We should also see that there are still some problems and challenges in the development of digital trade in China, such as the imperfect data infrastructure, the need to improve the rules system, the need to upgrade the open platform, and the need to improve the competitiveness of business entities. In the next step, we should focus on solving the problems in the field of digital trade and strengthen international open cooperation. Accelerate the construction of data infrastructure, promote the interconnection of international data infrastructure, actively meet the requirements of international economic and trade rules, and constantly improve the digital trade rules system, so as to create a good environment and provide strong support for the development of digital trade.

　　Put on AR glasses to challenge virtual darts, you can play the piano without a teacher, and play with AI chess robot & HELIP; … After visiting the number trade fair, some people described it as "Guo ‘ Future ’ One day. " In the digital age, digital trade will play a greater role. Making full use of the global digital trade Expo platform, discussing cooperation, promoting development together and sharing achievements will certainly make digital trade a new engine for common development and inject new momentum into world economic growth.

　　CCTV News:What new changes have taken place in vegetable prices since May?

　　In Beijing Xinfadi Market, merchant Jin Hao told reporters that since May, with the centralized harvest of vegetables in many places across the country, the price of vegetables in the Beijing market has dropped significantly.

　　According to merchants, recently, many vegetables have been converted from greenhouse to open field production, and the production cost has been further reduced, which has promoted the decline of vegetable prices.

　　Statistics show that the weighted average price of vegetables in Beijing Xinfadi Market in May was 1.06 yuan per catty, down 10% from April and 7.8% from the same period last year. Nationally, in May, the national average wholesale price of 28 kinds of vegetables monitored by the Ministry of Agriculture and Rural Affairs was 1.95 yuan per catty, down 12% from the previous month and 5.1% from the same period last year. In terms of varieties, the prices of 22 kinds of vegetables decreased month-on-month, among which Chinese cabbage, young garlic and green pepper decreased by more than 20% month-on-month.
