Stills of "Pretending to be a Lover"

　　　 The 14th Shanghai International Film Festival, which opened on the 11th of this month, was full of stars. The reporter learned on June 16th that the film festival will end on the 19th, and Bo Huang and Jiang Yiyan, who have performed well on the opening red carpet but have never joined hands, will become "pretend lovers" on the closing red carpet, representing the cast of "pretend lovers" as the finale of the Shanghai International Film Festival.

I don’t regret missing the opening ceremony.

　　　 The red carpet at the opening of the film festival was full of stars. Bo Huang and Italian actresses Guxinata, Jiang Yiyan, Chen Kun, Liang Yongqi and Kwai Lun Mei all made a sensation when they walked onto the red carpet. Many viewers who care about "Pretending Couples" are curious about why they don’t walk hand in hand again. In this regard, Bo Huang said that every time he walks on the red carpet, he cherishes it. "I think it is enough to show the red carpet once. If it is repeated, it will not make much sense."

　　　 After finishing the opening red carpet, Bo Huang immediately returned to Beijing to shoot the TV series "The Militia Ge Er Dan" and missed the press conference of the Sino-Italian co-production "Things Out of Marriage"; And Jiang Yiyan has been busy rehearsing the new drama "July and An Sheng". As classmates, the two discussed it when they opened the red carpet, and they must be "amazing" together on the closing red carpet.

Conclude as a couple

　　　 The person in charge of the crew said that with the increasing influence of Shanghai International Film Festival, more and more people pay attention to the final winning competition film, so the closing red carpet is far more important than the opening red carpet. "Although we are ‘ Pretending to be a couple ’ But up to now, we have never attended any activities together, and our ‘ Couple ’ The image is hidden very deeply! " Bo Huang said. How the two appeared as "lovers" on the red carpet of the closing ceremony is highly anticipated.

　　　 It is reported that in order to be the finale of the film festival, the two men respectively adjusted their itinerary, asked for leave from their respective crews, and attended the grand "Pretending Couples" conference held in Shanghai Bona Yinxing International Studios one day in advance. This conference will also be the last major conference of domestic films in this film festival. "The good is always at the end, which I firmly believe." Bo Huang finally said.

BYD’s ＂Fuel-saving King＂ power space configuration is fragrant.

Security configuration is the focus of most consumers, and it may not be used very often, but it is necessary to have it just in case, and a more comprehensive configuration can often win more consumers’ love. There are many choices of cars now, as we said today. Let’s take a look at it next.

Let’s look at the appearance of destroyer 05 first. The front face of destroyer 05 presents a steady design style and looks very capable. Combined with the spirit of the headlights, it is very visual impact. The car is equipped with LED daytime running lights, automatic opening and closing, delayed closing and so on. Coming to the car side, the car body size is 4780MM*1837MM*1495MM, the car adopts eye-catching lines, and the car side presents a rounded design style, with large-sized thick-walled tires, which looks full of movement. In the rear part, the rear looks very simple, the taillights look very simple, and the whole looks very spiritual.

In terms of interior, the interior shape of destroyer 05 looks elegant, which is in line with the tastes of young consumers. The steering wheel of the car is very in line with the interior style, made of leather, and the shape is clean and refreshing. Take a look at the central control, with the 12.8-inch touch-sensitive LCD central control screen, which makes the interior design quite layered and meets the aesthetic standards of most consumers. The dashboard and seats are equally eye-catching. The car is equipped with a dynamic dashboard, which looks very fashionable and simple. The car adopts imitation leather seats, and the seat wrapping is in place, and the overall comfort and wrapping are not bad.

The car is equipped with traction control (ASR/TCS, etc.), Bluetooth /WIFI connection, cruise control, voice control, intelligent key and other configurations. The configuration performance is passable and basically satisfactory.

The model class introduced today is the most considered class when many people buy their first car, mainly because the size of this class is moderate and the price is reasonable. If you have plans to buy a car now, then today’s car is worth learning about.

Bring AI to Life Baidu map makes travel easier because of technology.

In recent years, the Internet industry has changed dramatically, and with the opening of the curtain of AI industrialization, it is showing a new development trend. On November 16th, 2017 Baidu World Congress was held in Beijing. Under the theme of "Bring AI to Life", Baidu AI began to be productized.

AI-driven map function iteration brings users an intelligent travel experience.

The 2017 Baidu World Congress announced that AI should enter ordinary people’s homes from laboratories and high-end technology forums and integrate into people’s daily lives. Faced with the increasingly complex travel needs of human society, Baidu Map takes artificial intelligence technology as the core to drive the iteration of the map, upgrading from a single navigation tool to an "intelligent travel steward" that can change the way of human travel, bringing many unprecedented travel experiences to users.

Thanks to the continuous self-evolution of artificial intelligence technology and the increasing strength of R&D technology, the iterative speed of Baidu map update has obviously accelerated. Since the beginning of this year, the intelligent voice technology of Baidu map has made continuous progress. Users can adjust the intelligent voice function by opening Baidu map and shouting "small degree", which can check the route, query point, limit number, weather and other information by voice, and simultaneously support destination change, route change, road condition query and other operations in navigation. "GO Travel" is the first function launched in Baidu map industry, which transcends the limitation of planning routes by means of transportation in traditional map navigation, and combines "taxi+subway" and "cycling+subway" to calculate roads, truly providing optimal and cost-effective travel strategies around users’ needs.

In 2017, artificial intelligence was widely mentioned by people, but for Baidu map, which took the lead in AI, it has long taken the lead in big data, deep learning, human-computer interaction and image recognition. Baidu map has become the "traffic brain" in the era of artificial intelligence with over 80 billion times of location service and over 300 million kilometers of navigation service every day.

"Smart" index "Real", changing the way users travel.

Baidu map not only realizes a high degree of intelligence in functional design, but also brings smarter travel choices, more reasonable time management and more economical travel costs to the public. It also introduces AI technologies such as image recognition and deep learning into map production, driving maps to approach the real world infinitely.

According to the statistics of the Traffic Management Bureau of the Ministry of Public Security, by the end of March 2017, the number of motor vehicles in China had exceeded 300 million for the first time, including 200 million vehicles and over 364 million drivers, including 320 million drivers. The users who are "on the road" are large in scale and long enough, which will inevitably bring the problem of congestion.

Baidu map identifies the density of vehicles on the road through AI image recognition technology, which directly hits the essence of "many cars" congestion, effectively solving the congenital problem that traditional map speed calculation relies heavily on trajectory speed, "knowing the speed, but not knowing the number of vehicles". Based on the pioneering "multi-habitat combined collection mode", image deep learning technology, automatic and accurate identification of panoramic images and automatic difference of multi-source data, the efficiency of data collection, processing and updating has been improved exponentially. Baidu Map can help drivers realize "intelligent traffic avoidance" based on big travel data while predicting "traffic jams".

With artificial intelligence as the core, Baidu Map is setting off a revolution in the field of travel, which is based on intelligent voice technology, intelligent blocking avoidance based on big data cloud computing, and personalized travel plan based on user portraits. Baidu map deeply integrates the advantages of artificial intelligence technology with daily travel scenes, realizing the leap-forward transformation from tools to platforms, and bringing people smarter travel choices and more humanized use experience.

★ LI

　　Unlike AITO’s celebration of entering the Breaking Ten Thousand Club, it is ideal to deliver a total of 4,571 new cars in August. It’s a bit embarrassing in the new power. However, this should be the "pain" in LI’s progress. At present, it is at the end of Li ONE’s life, and the production capacity of the ideal L9 has not completely climbed, so it is understandable that there is a short-term "green and yellow" state.

Home of the car

　　At present, it is ideal to hold a large number of orders for L9. In November this year, the next new car L8 will also be released and delivered, as well as factories in Changzhou Phase II, Chongqing and Beijing. We believe that the ideal sales volume will return to a reasonable level.

■ Edit comments

　　The sales comments in August have come to an end here. At present, there are still many brands that have not announced their sales, and we are also waiting for good news. After the summer heat passed, it immediately ushered in the classic "Golden September and Silver 10" in the automobile industry, which officially rushed to a good period of sales. Major car companies have also prepared a lot of heavy models in the third and fourth quarters. How will their arrival change the sales of major car companies? Please continue to pay attention to car home’s sales reviews, and we will be there next month. (Text/car home Xing Yueyang)　

An official interpretation of the total national marine production in 2023 of 99097 billion yuan.

　　Cctv newsThe year 2023 is the first year to fully implement the spirit of the 20th National Congress of the Communist Party of China, and the year of economic recovery and development after the transition of epidemic prevention and control in COVID-19 for three years. Under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, coastal areas and sea-related departments have thoroughly implemented the decision-making arrangements of the CPC Central Committee and the State Council, made efforts to expand domestic demand, optimize the structure, boost confidence, and prevent and resolve risks. Macro-policies in the marine sector have continued to be effective, the resource supply capacity has been steadily improved, the independent innovation capability has been continuously enhanced, and the marine economy has recovered strongly, with both quantity and quality rising.

　　The strong recovery of marine economy helps the national economy to rebound.　　

　　The marine economy boosted the national economy by 0.4 percentage points.According to preliminary accounting, the total marine production in 2023 reached 9,909.7 billion yuan, up 6.0% from the previous year and 0.8 percentage points higher than the national economic growth rate, showing a strong recovery trend. The gross marine production accounted for 7.9% of GDP, an increase of 0.1 percentage points over the previous year. Among them, the added value of marine industry was 4,071.1 billion yuan, the added value of marine scientific research and education was 634.5 billion yuan, and the added value of marine public management services was 1,660.6 billion yuan, driving the added value of marine related industries to 3,543.5 billion yuan.

　　The growth rate of marine manufacturing industry is higher than that of the whole country.In 2023, the added value of marine manufacturing industry was 2,986.1 billion yuan, an increase of 7.0% over the previous year and 2 percentage points higher than the national manufacturing growth rate. Among them, the added value of marine shipbuilding industry was 115 billion yuan, up by 17.6% over the previous year. The development of high-end, intelligent and green shipbuilding has been solidly promoted, and it has entered a new period of product whole spectrum development.

There is a strong demand for China’s chemical products in domestic and foreign markets, and the production and sales have increased. The added value of marine chemical industry is 434.3 billion yuan, up by 10.0% over the previous year.

　　Marine service industry boosts national economic growth.In 2023, the added value of marine service industry was 5,896.8 billion yuan, accounting for 4.7% of GDP, which boosted the national economy growth by 0.3 percentage points and contributed to the national economy growth. Contact and aggregation services recovered quickly, with the added value of marine transportation industry reaching 762.3 billion yuan, up 8.5% over the previous year, and the cargo throughput of coastal ports reaching nearly 11 billion tons. The added value of marine tourism was 1,473.5 billion yuan, an increase of 10.0% over the previous year. Residents’ tourism demand was released, and cruise ships resumed in several cruise ports.

　　Guarantee of resource supply and lay a solid foundation for high-quality development　　

　　The protection of marine space resources elements has been continuously strengthened.There are 2,162 newly approved sea island projects and 3.133 million mu, up by 30.2% and 7.3% respectively year-on-year, involving an investment of over 1 trillion yuan. The demand for sea islands for major infrastructure such as oil and gas, nuclear power and liquefied natural gas is strong. A series of policies have been issued, such as the Notice of the Ministry of Natural Resources on Further Improving the Protection of Land Use and Marine Elements and the Notice of the Ministry of Natural Resources on Exploring and Promoting the Three-dimensional Stratification of Sea Areas, to promote the continuous improvement of the level of economical and intensive utilization of sea areas and islands. The first demonstration of "Hemei Island" was launched, and 33 islands in China were selected. The efforts of marine ecological protection and restoration have been continuously increased. Since the 14th Five-Year Plan, the central government has invested 15.6 billion yuan to support coastal cities in implementing 63 marine ecological protection and restoration projects, among which 16 new marine ecological protection and restoration projects were implemented in 2023.

　　The supply capacity of marine energy, food and water resources has been steadily improved.One isRemarkable achievements have been made in increasing the storage and production of offshore oil and gas. New discoveries have been made in the exploration of 2.6-600 million tons oil fields in Bozhong, and the output of offshore crude oil and natural gas increased by 5.8% and 9.1% respectively year-on-year. The increase of offshore crude oil accounted for more than 60% of the total increase of crude oil in China for four consecutive years, which became a key increase in energy production. Offshore wind power generation increased by over 17% year-on-year, providing strong support for ensuring national energy security.The second isThe promotion of deep-sea aquaculture has been accelerated, and the supply capacity of high-quality seafood has been continuously improved. The output of marine aquatic products has exceeded 35 million tons, up nearly 3% year-on-year. The number of national marine pasture demonstration zones has reached 169, 16 more than in 2022. New progress has been made in the manufacturing, production and operation of deep-sea aquaculture equipment in coastal areas.The third isThe scale of seawater desalination projects continued to expand, and the large-scale utilization of seawater desalination was actively promoted. The seawater desalination projects in Tianjin, Shandong, Zhejiang and other places were steadily advanced, and the scale of projects under construction and newly started exceeded 300,000 tons/day.

　　Three major demands drive the marine economy to rise in quantity and quality.

　　Consumption in the marine sector continued to recover.With the obvious effect of various policies and measures to expand domestic demand and promote consumption, the consumer demand of residents has been accelerated, and the marine tourism consumption market has obviously picked up, which has led to the rapid recovery of service consumption such as accommodation, catering and transportation in coastal areas. In 2023, ocean passenger traffic and ocean passenger turnover increased by 122.3% and 125.4% respectively. In 2023, the tourism revenue of Jiangsu and Hainan increased by 45.7% and 71.9% respectively, which exceeded the level of 2019. Marine tourism consumption tends to be diversified, and integrated formats are constantly emerging. The modes of "performing arts+marine tourism" and "museum+marine tourism" have become new hotspots. Residents’ diet is gradually upgrading to quality, and the consumption market of marine aquatic products is booming. In 2023, the national import of aquatic products increased by 4.7% year-on-year, and the price of marine aquatic products increased by 3.9% year-on-year.

　　Investment in marine fixed assets is growing well.In terms of port construction, from January to November, the investment in fixed assets of coastal ports was 83.5 billion yuan, up 16.8% year-on-year, and the growth rate was 10.5 percentage points faster than that of the same period of last year, further improving the level of port greening and intelligence. The construction of cross-sea high-speed rail and submarine tunnel continued to advance. The cross-sea Fuxia high-speed rail with a total investment of 53 billion yuan, the Dalian Bay submarine tunnel and extension line were completed and put into use, and a number of major marine engineering projects entered a new stage.

　　The volume of marine foreign trade has been steadily improved.In 2023, in the face of multiple risk challenges such as sluggish international demand and international geopolitical uncertainty, China’s marine shipping industry led the world in terms of three major indicators: the number of completed ships, the number of new orders for ships and the number of orders for hand-held ships. The export value of ships was increased by 35.4% year-on-year. With the substantial increase in the export scale of new energy vehicles in China, the number of new orders for automobile carriers accounted for 82.7% of the global total. In 2023, the container throughput of international routes in China’s coastal ports increased by over 4% year-on-year, and the foreign trade cargo throughput of coastal ports increased by nearly 10% year-on-year.

　　Scientific and technological innovation leads the construction of modern marine industrial system

　　Platform construction promotes industrial innovation support and service ability.The National Marine Science Data Center has been running steadily, the submarine data center has been laid out quickly, and the innovation center for marine metrology and detection technology has been established. The National Marine Pharmaceutical and Biological Products Industry Alliance was formally established, exploring a new mechanism and new model of enterprise-oriented, market-oriented and "Industry-University-Research Gold" collaborative innovation cooperation. The completion of the first phase test area of Tianjin Lingang seawater desalination and comprehensive utilization demonstration base will solve the verification problem of large-scale application of key seawater desalination equipment.

　　Technological breakthrough accelerates the birth of new kinetic energy for industrial development.The megawatt tidal current generator "Endeavour" has been running continuously for more than 20 months, and the cumulative power transmission has exceeded 2.7 million kWh. The completion of the sea trial of the 20 kW floating thermoelectric power generation device marks a key step for the development and utilization of marine thermoelectric energy in China to be applied on a large scale at sea. China’s first self-developed megawatt wave power generation device "Nankun" successfully went to sea trial. The world’s largest 20 MW semi-direct drive permanent magnet wind turbine was successfully rolled off the assembly line, and the 2,500-ton self-propelled jack-up wind power installation platform "Haifeng 1001" independently developed and designed was officially delivered. The hoisting of offshore wind turbines with a single capacity of 16 MW was completed, 18 MW was off the assembly line, and the experimental base of 25 MW was approved.

　　The application of green and digital intelligence technology drives industrial integration and transformation and upgrading.New progress has been made in the integrated development of "offshore wind power+",and for the first time, the deep offshore floating wind power platform is directly supplied to offshore oil and gas fields.

　　In 2023, the national marine production value was 99097 billion yuan, an increase of 6.0% over the previous year.

A ＂circle of friends＂ takes 10 minutes to find the lost children, and this police station in Yiwu Public Security is connected with 120,000 residents online.

　　"Has anyone seen a child? My child is gone! "

　　One day in May, Wang Li, the instructor of the E-commerce Police Office of Jiangdong Police Station of Yiwu Public Security Bureau, suddenly heard such a cry and ran out of the police office. She soon learned the reason: the mother took her daughter to buy medicine in a nearby pharmacy, but she didn’t pay attention for a while. The child was gone.

　　E-commerce Police Office is located in Liuyu Village, Qingyan, Jiangdong Street, Yiwu, which is known as "the first village of online stores in China" and a hot spot of "mass entrepreneurship and innovation". At present, more than 4,000 online stores have settled in, bringing together more than 25,000 entrepreneurs across the country. In such a large floating population, lost children need to be found quickly.

　　Wang Li immediately posted a special "WeChat circle of friends" containing the characteristics and clothes of the lost girl. After more than ten minutes, someone contacted, "There is a child here who looks like what you are looking for." Wang Li took people to find it, and it was indeed a lost child.

　　Through a "circle of friends", the lost children were found in 10 minutes, thanks to a pioneering work of Jiangdong Police Station.

　　Grassroots policing also needs digital tools.

　　The circle of friends searching for people originated from Wang Li’s corporate WeChat, which can directly reach more than 2,000 residents around the e-commerce police office.

　　The head of the publisher is dressed in a police uniform, and there is the identity of "@ Jiangdong Police Station" after the name. People who find clues can chat with the police instructor directly by clicking on the head. This is the key to quickly find the lost children.

　　This situation does not only appear in the e-commerce police office. In fact, the entire Jiangdong police station has established a smart policing platform based on enterprise WeChat, that is, "WeChat policing". It has also been combined with the work of "Party building+unit+policing" and "one village and one auxiliary police" based on WeChat, and achieved very good results.

　　Jiangdong Street is located in the center of Yiwu, which is the largest and narrowest area among several streets in the city. The street has a local population of 87,000 and a foreign population of 217,000, including nearly 3,000 foreigners. It is the most alert and complicated area in Yiwu and even the whole Jinhua area, and efficient and convenient communication channels between the police and the people are very necessary.

　　Yiwu Jiangdong Street has a cluster of online merchants, developed logistics, and the gradual spread of 5G networks. The unique resource advantages have made digitalization a breakthrough in public security grassroots innovation.

　　Can the auxiliary police at the grass-roots level have a continuous and efficient contact with the residents in the jurisdiction with the help of tools?

　　At this time, Tencent’s enterprise WeChat attracted the attention of the leaders of Jiangdong police station: free tools, interoperability with WeChat, and more members and external relationship management functions were the reasons for them to decide to give it a try.

　　It is a valuable experience of Jiangdong police station to sink the police and auxiliary police into villages and communities. On April 29th, Jiangdong Police Station officially launched the work of "one village and one auxiliary police" in the village. More than 100 policemen and auxiliary police officers in charge of grass-roots policing have their own "exclusive" service areas, and they have a new identity: resident police instructors.

　　With the full operation and maintenance support of Tencent’s official WeChat service provider, the first enterprise WeChat platform of "Public Security Police Station" in China has also been launched. The identity of police instructors is bound to their own enterprise WeChat accounts, and residents in the jurisdiction only need to use WeChat to add them. Moreover, in the eyes of residents, they have both officially certified business cards and friends who can communicate at any time in the address book.

　　The first attempt achieved good results. On the afternoon of May 24, Ms. Zhou, who lives in Jiangdong, encountered a common scam when she visited the supermarket. She won a "grand prize" with the supermarket vouchers, and she only needed to make up the difference to get a "valuable" jade bracelet.

　　The heart-warming Ms. Zhou hesitated to make up the difference. Soon, she remembered the police instructor Wang Yuqiang she had added and sent a message to ask. Seeing the news, Wang Yuqiang immediately called a voice call. He reminded Ms. Zhou to carefully measure the physical value of the bracelet and avoid impulsive consumption.

　　"If it weren’t for instructor Wang’s timely reminder, I would have bought the bracelet impulsively at that time, so I regretted it and couldn’t find a place to make sense." When she mentioned the experience of "lucky draw", Ms. Zhou looked lucky.

　　Resolve contradictions and disputes on the spot

　　At the end of the police station, from the leader as the manager to the front-line auxiliary police, there is also a great need for a tool to improve efficiency.

　　The high incidence and complicated police situation put a lot of pressure on Jiangdong police station. According to Lou Xiaolei, director of Jiangdong Police Station, in normal times, the police station handles nearly 100 police cases every day on average. Among them, in addition to common cases such as property infringement and gambling on drugs, during this year’s epidemic, new telecommunication network fraud involving masks, temperature guns and helmets also appeared frequently. "In addition, some economic disputes, consumer disputes, family disputes, and non-police alarms such as getting lost, asking for help, drunkenness, noise and moving cars. 110’ Alarm ",

　　This represents the people’s trust in the police, but at the same time, the non-police situation consumes a lot of police force and often consumes the safety satisfaction of ordinary people.

　　"Controlling cases and reducing police situation" is the main line of the work of grass-roots police stations. Accusing a case requires pre-publicity by the police and timely intervention before the case occurs; On the one hand, it is necessary to prevent and stop telecommunication network fraud cases as much as possible, on the other hand, it is necessary to try to resolve disputes and non-police conflicts on the spot. At the beginning of this year, the new team of Jiangdong Police Station took the lead in proposing the goal of creating a "Fengqiao-style police station", that is, "small things don’t leave the village, big things don’t leave the town, contradictions don’t be handed over, and conflicts are resolved on the spot".

　　Under the leadership of Lou Xiaolei, corporate WeChat has become a "good helper" for "controlling the case and reducing the alarm".

　　The e-commerce economy in Jiangdong street is developed, and telecommunication network fraud is high. Anti-fraud propaganda is also the top priority of Jiangdong police station. Now, the resident police instructor can send the anti-fraud propaganda uniformly produced by the police station to WeChat friends in the jurisdiction through the enterprise WeChat. This method is more accurate than distributing leaflets and posting posters.

　　In order not to disturb residents too much, police instructors also conduct anti-fraud propaganda through the "customer circle of friends" function of enterprise WeChat. Its content can be edited by the police station and then pushed to all police instructors with one click. They just need to click "OK" to synchronize the content.

　　These two methods also bring a very practical benefit: "zero cost", which can save tens of thousands of yuan each time compared with the receiving group of hundreds of thousands of people who send short messages in groups through operators.

　　The anti-fraud propaganda sent by police instructors accurately prevented a fraud case of pretending to be a school teacher to collect training fees.

　　Enterprise WeChat is also a good reporting channel to help police stations crack down on illegal crimes.

　　On May 20th, Mr. Li, a resident, contacted Wu Wentao, a police instructor, through the enterprise WeChat to provide clues to help solve an online gambling gang case, involving a "tap" of up to 200,000 yuan.

　　Smooth communication channels between residents and police instructors in the jurisdiction are also of great help to resolve conflicts on the spot and absorb the police situation.

　　Jimingshan Community in Jiangdong Street has a total population of 35,000, including 25,000 foreigners from 31 provinces, more than 2,000 residents from 29 ethnic minorities, more than 1,300 foreigners from 74 countries and more than 3,500 local residents. It is called "United Nations Community".

　　In response to frequent police incidents, the police instructors in Jimingshan Community use corporate WeChat to handle the help and disputes of residents in the area at any time. "Even at 11 o’clock or 12 o’clock in the evening, if our team members receive it, they will reply in time," said Jin Xiaowei, the stationmaster of Jimingshan Community Police Guidance Station. "Moreover, corporate WeChat can take screenshots, send pictures, and have voice or video conversations, which is more intuitive than telephone calls."

　　This has caused many disputes and non-police police situations to be quickly resolved. From April to June 2019, there were more than 1,130 police situations in Jimingshan community, which dropped to more than 700 in the same period this year. "The police situation has declined, and the people’s sense of security and satisfaction has naturally improved."

　　Connect 120,000 residents in the jurisdiction.

　　With the initial results of the "WeChat policing" model, Jiangdong police station felt greater responsibility, and they began to think about two more important issues: how to connect more residents in the jurisdiction? What other digital capabilities can be combined with grassroots policing?

　　It is not easy to add WeChat of residents in the jurisdiction on a large scale.

　　"Tower Group" provides "seed users" for police instructors, and some landlords and tenants will actively add them through the corporate WeChat business cards shared by the group, but after this wave, the real test will come.

　　Each police guidance station of Jiangdong Police Station has its own magic power.

　　Huang Pengfei, the stationmaster of Wuai Community Police Guidance Station, uniformly printed the corporate WeChat business cards for the police instructors. When doing the registration of floating population, fire protection propaganda and anti-fraud propaganda on a daily basis, he would specially ask everyone to bring business cards and introduce the benefits of adding police instructors from door to door.

　　In less than two months, five police instructors in Wuai Community have added more than 5,600 friends. As of mid-June, 72 police cases have been handled through corporate WeChat, including asking for help, lost children, theft, fraud, economic disputes, housing disputes, etc. "Many people will directly report their problems through corporate WeChat, and there are private telephones on our corporate WeChat business cards. Some things are urgent, and they will call directly with a phone call."

　　The police instructors in Jimingshan community also used this "street fighting" approach. The stationmaster Jin Xiaowei even asked the team members to post the corporate WeChat business card on the back of their mobile phones and promote it at any time during their daily visits. "The idea I gave them was ‘ Always think about it in your heart and promote it at any time ’ 。”

　　In addition, in the conspicuous position of the village (neighborhood) Committee, including the counters of restaurants and express delivery points, the QR code of the corporate WeChat of the police instructor was also posted. "Residents may not add it at first, but when something happens, he will think of it and contact us directly after adding it."

　　By June 30th, Jiangdong Police Station had added more than 120,000 WeChat accounts through the real-name certified enterprise WeChat accounts within two months. It is equivalent to that nearly half of the residents in Jiangdong area have established direct contact with police officers.

　　According to statistics, since the launch of the enterprise WeChat of Jiangdong Police Station, it has received more than 16,000 police consultations in just two months. Among them, 237 cases were guided to properly handle the police situation, more than 1,400 people were asked for help, 3,154 people were declared by the floating population, 276 cases were consulted on online fraud, 32 cases were stopped from online fraud, and more than 11,000 people were consulted on contradictions and disputes, household registration business and residence declaration.

　　At the same time, the total police situation in Jiangdong Police Station decreased by 10.94% from May to June this year, among which the police situation of telecommunication network fraud decreased by 17.91% and the police situation of disputes decreased by 22.15% compared with the same period of last year. …….

　　Behind connecting residents is the initial intention of Jiangdong police station to truly serve the masses.

　　Jiangdong police station is still exploring more digital capabilities.

　　For example, they hope to use the video conference function to arrange the work for the police instructors in the village; In the process of contradiction and dispute mediation, we can also try to let lawyers and mediators participate through video conference to break through the time and space restrictions; The hottest webcast at the moment can also be used for anti-fraud propaganda.

　　In their idea, Jiangdong Police Station can even be combined with enterprise WeChat to create an "online police room". In addition to the simple graphic, audio and video communication between police instructors and residents, it can also be based on the API interface opened by enterprise WeChat to move more and more complex police services online in the form of small programs, so that each resident auxiliary police can play a greater role.

　　"Our current police are really hard. They work in three shifts and have to deal with twenty or thirty police situations a day. Now we have absorbed some police situations through the prevention and treatment of "WeChat policing", which is a great burden reduction for them and a more intimate policing service for ordinary people. "

How does ＂Panda＂ capture dark matter？

　　In Liangshan, Sichuan, there is a place 2500 meters underground. In this "China Jinping Deep Underground Dark Matter Laboratory", there is an experimental hall 40 meters long, 6.5 meters high and 8.5 meters wide. This is the deepest and best underground laboratory in the world at present, and it is also the place where the "Panda Project" is implemented.

　　In Columbus, Ohio, USA, it was reported at the 2017 International Conference on High Energy Particle Astrophysics a few days ago that China’s "Panda Project" project team issued the strongest restriction on the measurement of dark matter particle properties, and China scientists once again took the lead in the sensitivity of direct detection of dark matter and took the lead in achieving significant detection results. This is the second time that the "Panda Project" released the most sensitive dark matter detection results in the world after the first detection results of the 580 kg detector were released two years ago.

　　What is dark matter? There is dark matter in the universe, dark matter in galaxies, and dark matter around us, but we can’t see it with our eyes. It is silent and difficult to leave traces. It does not emit electromagnetic waves of any band, nor does it interact with any electromagnetic waves. Because there is no direct electromagnetic interaction with ordinary matter, dark matter does not emit light, which is similar to "ghost" and cannot be seen in the usual way. Nevertheless, dark matter should not be underestimated by anyone, because the research and analysis so far show that dark matter accounts for more than 80% of the total mass of cosmic matter.

　　Uncovering the essence of dark matter particles is one of the most important scientific goals in physics and astronomy in the 21st century, and the international scientific research on detecting dark matter particles is in full swing. In order to detect dark matter, scientists have thought of many methods. The method of China’s "Panda Project" is to hit a xenon atom as a target. If dark matter particles collide with the xenon atom, this collision will be converted into recoil energy of the xenon atom, and a photoelectric signal will be sent out, which will be captured by the detector.

　　In the view of Dr. Ji Xiangdong, the leader of the Panda Project and professor of Hongwen at Shanghai Jiaotong University, scientists’ method of detecting dark matter particles is similar to "waiting for a rabbit". Dark matter particles are like rabbits running in droves, and xenon atoms are like a tree in the forest. It is inevitable that one or two rabbits will be killed under a tree and become the trophy of scientists. The crux of the problem is that there are not only rabbits in the big forest, but also lions, tigers and other animals. Whoever bumps into them is louder than rabbits. Therefore, to find a "forest" with no or few other creatures, China Jinping Underground Laboratory is the ideal "forest".

　　In Jinping Mountain, Sichuan, there is a 2400-meter-high mountain cover, just like a natural barrier blocking cosmic rays. According to the measurement, the cosmic ray flux in the laboratory can be reduced to one-tenth to one-hundredth of the ground level. However, the underground laboratory is located in marble instead of granite, and its natural radioactivity is quite low. Experimental tests show that its natural radioactivity is lower than that of rocks outside the cave, which provides very good conditions for dark matter direct detection experiments.

　　Under this condition, in the past year, the long-term operation of the 580 kg liquid xenon detector in China has improved its sensitivity to the interaction between dark matter and ordinary matter by more than four times. However, the 580 kg liquid xenon detector used in the "Panda Project" has not detected a collision event of dark matter particles, so China scientists have reached the upper limit of collision probability. This discovery has once again set a new world record for limiting the properties of dark matter particles.

　　In scientific research, finding a road is as important as blocking a road, and "not seeing it" is equally meaningful.

　　As one of the most important mysteries in basic physics, the study of dark matter has attracted many physicists all over the world to work hard for it. Several international cooperation groups are working hard to "catch" dark matter. In order to seize the opportunity, it can be said that every minute is lost. All experimental cooperation groups expect to be the first to find the signal of dark matter particles, and the international competition for dark matter detection is fierce.

　　In the international dark matter detection competition, the LUX cooperation team of the United States, which has finished its operation, officially released the final data of the 250 kg detector in the past four years in January 2017, exceeding the world’s most sensitive detection results published by the Panda Project in July 2016. The XENON1T detector located in Italy has become the largest dark matter detector in operation in the world at present, and the amount of liquid xenon in the detection area is 2 tons. This experimental cooperation group also published the first result in May this year, and its sensitivity once again surpassed that of LUX in the United States.

　　Although the volume of the second phase detector of "Panda Project" is less than one-third of that of XENON1T in Europe, the cooperative team has obtained the latest detection results beyond XENON1T through the continuous and stable operation for nearly half a year, and achieved the second lead.

　　Chen Hesheng, an academician of the China Academy of Sciences and former director of the Institute of High Energy Physics of the Chinese Academy of Sciences, said that the latest results of the second phase of the Panda Project show that the deep dark matter detection experiment in China has been at the international leading level; Zhao Zhengguo, an academician of China Academy of Sciences and an experimenter of high-energy physics, thinks that it shows that scientists in China can make international leading achievements in the most advanced fields of exploring the universe and nature, and also in China.

　　Talking about the next step, Liu Jiang, a scientist of Panda Project and a professor of Shanghai Jiaotong University who is in charge of experimental data analysis, said that the first step is to increase the volume of the detector and the second step is to reduce the noise as much as possible. He revealed that preparations for the next generation of detectors are in full swing, and the 580 kg liquid xenon dark matter detector being used is upgraded to 4 tons. The components of the new detector are already under construction, followed by assembly, alignment and testing. Scientists in China hope to stop the operation of the 580 kg liquid xenon detector in 2018, fully carry out the experiment of the upgraded detector, and strive to obtain the first batch of data of the new detector in 2019.
