Paris failed to take away the victory.

Dortmund beat Paris at home in the Champions League semi-final

In the early morning of May 2, Beijing time, Dortmund played at home against Paris Saint-Germain in the first leg of the Champions League semi-final.

With the only goal scored by center fuellkrug in the whole game, Dortmund won 1-0 to take the lead in promotion, which is Dortmund’s fifth clean sheet in the Champions League this season, more than other teams.

In the last 11 Champions League home games, Dortmund has 7 wins and 4 draws and remained unbeaten. At present, only Manchester City (31 games), Bayern (16 games) and Real Madrid (12 games) have more unbeaten home games in the Champions League than Dortmund. In this game, Dortmund striker Sancho performed well, with 12 passes and 13 successful confrontations.

Dortmund coach Terzic said after the game, "This is a well-deserved victory, thanks to the excellent performance of the team. We could have scored more goals, but so could they, which is why the result is good in my opinion. We run a lot, which is necessary in such a game. "

Fuellkrug scored the key goal.

In all competitions this season, this is the first time that Paris has failed to score and lost the game. In the last 15 Champions League away games, Paris’ record was only 4 wins, 4 draws and 7 losses. Compared with Sancho’s brilliant performance, Mbappé played the single arrow instead of his familiar left wing, and the French number one striker was a little lost.

However, Paris had lost 1 goal in the first leg of the European War two-leg knockout six times before, but it was able to make it through four times. The latest one happened to be against Dortmund. In 2020, they eliminated Dortmund 1-2 away and 2-0 at home.

Head coach Enrique expects the team to rise. "Everyone knows that this is not easy. This is the semi-final of the Champions League, and the atmosphere in the dressing room is a bit low, especially after hitting the goalpost twice. But throughout the game, our fans have been encouraging us. "

Liaoning team won the first round.

In the first match of CBA semi-final, Liaoning won Guangdong.

On the evening of May 1, Beijing time, the CBA semi-final match between Liaoning and Guangdong started. With Zhang Zhenlin’s excellent performance of 14 points and 2 steals in a single quarter, Liaoning played a small climax in the third quarter and finally beat Guangdong 119-97.

In this game, qi zhou, the main inside player of Guangdong team, was suspended. Zhang Haojia, a teenager who replaced qi zhou, obviously didn’t make sufficient preparations. He got three fouls in the first three minutes, and Du Feng, the coach of Guangdong Men’s Basketball Team, was forced to send Huang Mingyi, a younger player, to play.

However, in the first half, Xu Xin, the inside line of Guangdong team, played fairly steadily. Zhang Mingchi hit three long shots on the outside line, helping the team to bite the score 56-59 at half-time. "These’ post-00′ players dare to fight and fight in the game. I am generally satisfied with the performance of young players." Du Feng concluded after the game.

The game changed suddenly in the second half. Zhang Zhenlin, who had a positive and negative value of -6 in the first half, suddenly woke up. Not only was he able to hit a difficult three-pointer, but he also intercepted the opponent’s pass twice to fight back, leading the Liaoning team to play a 30-14 attack wave in the third quarter, laying a lead of nearly 20 points.

In the last quarter, the Guangdong men’s basketball team once improved its defensive intensity, but the effect was not obvious. Finally, it lost the first game of this round of best-of-five series.

Yang Ming, coach of Liaoning team, said after the game that Guangdong team without qi zhou was not complete, and the team still had to prepare for difficulties.

In terms of data, four Liaoning players scored in double figures, among which Zhang Zhenlin scored 34 points, 7 rebounds and 4 steals, while Zhao Jiwei scored 19 points and 14 assists. Jeff and Waters scored 20 points and 19 points respectively in the backcourt of Guangdong Men’s Basketball Team.

The next showdown between the two sides will be held on the 3rd, when qi zhou will lift the ban and come back. The good news for the Liaoning team is that Guo Ailun, who has been absent for a long time due to injury, has appeared in the arena, but the club has not disclosed the exact time of his comeback.

In this game, Shenhua only started with two foreign AIDS, and head coach slutsky also made some rotations on the lineup. "There are many players in our team who can rotate, and everyone is ready."

On November 10th, 2009, China Education News published a page titled "Integrated Full Coverage — — Chengdu promotes the balanced development of compulsory education and realizes a new leap, and reports the experience of Chengdu in coordinating the integrated development of urban and rural education.

　　■ A typical return visit to the magnificent 70-year struggle in the new era

　　The integration of urban and rural education is of great significance for promoting educational equity and social equity. In the process of promoting the integration of urban and rural education, various localities have made efforts to explore according to local conditions. In April, 2009, Chengdu, located in the west, became the only experimental area in China where the ministries, provinces and municipalities jointly built and coordinated the comprehensive reform of urban and rural education. On November 10th, 2009, China Education News reported the experience and achievements of Chengdu’s integrated development of urban and rural education in a colorful way. Through vivid cases and detailed data, it showed the experience and measures of Chengdu’s continuous deepening of comprehensive reform in the field of education, which caused great repercussions throughout the country.

　　Now, in the past 10 years, in the face of the people’s new expectations for diversified and high-quality education, the new standards of industrial transformation and upgrading and urban transformation and development for talent training, in the "2.0 era" of overall urban-rural integration development, Chengdu has practiced the development concept of "people-centered", shifted its focus to "global quality" and "high-level balance" and made a leap towards "excellent education in Chengdu". Recently, the reporter revisited Chengdu to explore the development footprint of Chengdu education under the vision of "Chengdu in the whole region".

　　"A game of chess" in the whole city and "a picture" in the whole region — —

　　Scientific layout planning, reshaping the spatial pattern of education

　　Peach blossoms bloom on Longquan Mountain, and egrets fly by Qinglong Lake.

　　Taking the subway to enjoy flowers and birds in the eastern suburbs of Chengdu is the most enthusiastic activity of Chengdu citizens in recent years.

　　A continuous follow-up interview with Qinglong Lake Primary School, which is located on the side of Qinglong Lake, reveals that the school is the same every year. "In the past, it was a sunny day with a dusty foot, but now the four seasons are different, and the campus is better than the garden."

　　Principal Liao Xiaoqiang told reporters that relying on the unique environment, the school has carried out campus culture and school-based curriculum construction with the theme of "ecological civilization". The once remote and unknown rural school has finally "turned over" and has repeatedly shared experiences on behalf of primary and secondary schools in Sichuan at various levels of ecological education forums in China. The educational concepts and teaching methods are at the forefront of development and have become a model for many urban schools to visit and learn.

　　It’s not just rural schools that have changed dramatically.

　　"where is the temple of the famous Premier, in a deep pine grove near the City of Silk", "The window contains the autumn snow in Xiling, and the Dongwu Wan Li boat is moored at the gate", "A thatched cottage in the west of Wan Li Bridge, and the water in Baihuatan is surging waves" … …

　　The reporter walked 100 meters away from the Hongzhuan West Road Primary School in Chengdu, along the Jinjiang River, the mother river of Chengdu, which is a greenway along the river for more than 100 kilometers, connecting Wuhou Temple, Wan Li Bridge, Baihuatan, Du Fu Caotang and other scattered humanistic holy places.

　　"Every step is beautiful, with history and allusions." Hongzhuan West Road Primary School puts the relevant parts of Chinese class, science and technology class and labor practice class in the greenway, so that students can get in touch with the beauty of nature and humanity at zero distance.

　　According to the overall plan of building a "park city", in recent years, Chengdu has built nearly 3,000 kilometers of urban greenways of different levels. These green "capillaries" string together many elements such as the development of young people’s quality and the practice base of popular science.

　　In the past, urban schools were small in space and limited in environment. Now, the characteristic courses, "greenway research" and social practice activities based on greenway provide rich educational materials for schools and open up a broad development space.

　　Greenway is not only a "green road", but also a "big school" and "big classroom" to improve students’ comprehensive quality.

　　The change of urban and rural schools is not only the epitome of Chengdu’s educational development, but also the historic change of Chengdu’s urban spatial pattern.

　　More than 2,000 years ago, Shu Shou Li Bing opened Dujiangyan, which turned western sichuan bazi between Longmen Mountain and Longquan Mountain into a "land of abundance" where "floods and droughts depend on people and hunger is unknown", and also fixed the basic pattern of modern Chengdu urban development.

　　Today, the population of Chengdu has increased by 500,000 per year, and it has developed into a mega-city with an actual population of over 21 million. western sichuan bazi, a city with two mountains, has become crowded.

　　Reflected in the field of education, the problems of "urban crowding" and the inability to keep up with public education services need to be solved urgently. According to estimates, according to the current average annual growth rate of the resident population in Chengdu, there is a need for a net increase of more than 70,000 degrees each year.

　　The key to solve the "urban congestion" and "educational crowding" lies in breaking the original urban spatial pattern.

　　The Master Plan of Chengdu (2016-2035) adopted last year depicts the grand blueprint of "one heart, two wings, one area, three axes and multiple centers". Nowadays, Chengdu’s urban development is crossing Longquan Mountain eastward and opening up new areas in the east. Longquan Mountain has become a new "city center" and "two mountains with one city" has become "one mountain with two wings".

　　As the "biggest livelihood project", education plays a fundamental, leading and overall role. In order to support urban development, Chengdu insists on "where the city is updated, where education follows, where the industrial layout is, where education is matched", and takes the lead in scientifically adjusting the layout planning of primary and secondary schools and kindergartens to adapt to the adjustment of urban spatial layout.

　　Since 2017, the Chengdu Education Bureau and the Municipal Planning Bureau have initiated the revision of the special plan for educational facilities, and revised and compiled the Layout Plan for General Primary and Secondary Schools and Kindergartens in Chengdu (2017— 2035), covering 22 districts (cities) and counties in the city, and unifying the compilation requirements and technical standards, truly achieving "a chess game in the city and a map in the whole region" and jointly creating "excellent education Chengdu".

　　On June 28, 2019, the city’s education conference made a major deployment of Chengdu’s education reform and development. After the education conference, the municipal party committee and the municipal government put forward the "three-step" goal of Chengdu education around the "three-step" strategic goal of Chengdu in the new era:

　　By 2022, it will initially build a modern education city that matches the national central city; By 2035, fully realize the modernization of education and build an international education highland with an important position in Pan-Eurasia; By the middle of this century, it will become a famous educational city with world influence.

　　The "Opinions" also clarified that it is necessary to support a large number of rural schools like Qinglong Lake Primary School through policies such as "new quality schools" cultivation and indicators reaching students, and carry out quality education and school culture construction of "one school, one product, one school and one scene" to promote the development of rural education characteristics and connotations.

　　Excellent city and beautiful countryside are the new goals under the new concept. In the future, according to the multi-center and group layout of urban development, with "15 minutes" as the radius, the "beautiful picture" that everyone can enjoy quality education is slowly unfolding.

　　Focus on the "global" and focus on the "county" — —

　　On the basis of "basic balance", promote the realization of "high quality balance"

　　In 2017, the 13th Party Congress of Chengdu put forward the urban spatial development strategy of "eastward expansion, southward expansion, westward control, northward reform and zhongyou".

　　From the description, it is not difficult to see that the east and south directions are the focus of urban expansion, while the west direction is the Longmen Mountain water conservation area and Dujiangyan irrigation area, which is the ecological conservation area where Chengdu strives to control the development intensity.

　　Pujiang County, located in the "western control" area, is an agricultural county with hilly terrain. The county’s GDP is less than 1% of Chengdu’s, and its fiscal disposable income is less than 1 billion yuan. It is such an ecological functional area that the financial situation has not affected the investment in education.

　　In an interview with Pujiang County, Yang Zhongyun, director of the County Education Bureau, counted an account for the reporter: in the standardization upgrading project of rural primary and secondary schools in Pujiang County in the past two years, the county’s total funds for upgrading educational equipment, environmental renovation and sports ground renovation were 99.34 million yuan, with a total investment of 33.95 million yuan … … The investment level is not worse than other regions.

　　Education prospers, and cities prosper. If the county is prosperous, the whole region will be prosperous. According to this idea, Chengdu requires district (city) and county governments to improve the education investment guarantee system of "supporting the weak and ensuring the bottom" and the compulsory education fund guarantee mechanism of "unifying urban and rural areas and focusing on counties", and at the same time, it requires educational construction projects and funds to give priority to ensuring the needs of areas and weak schools with seriously insufficient degrees.

　　The integration of urban and rural education is a dynamic development process, and the allocation of resources should also remain dynamic. In the process of policy formulation and implementation, Chengdu has made full use of the idea and method of "overall planning" and formed the idea of "giving policies to central cities, subsidies to suburban counties, and giving preference to suburban counties".

　　On the one hand, the project funds are shared and supported by a "dynamic tilt" system. For example, for the three-year standardized construction upgrading project of urban and rural primary and secondary schools with a total investment of more than 4 billion yuan, the central city, suburbs and outer suburbs will bear 100%, 70% (or 60%) and 30% (or 20%) respectively, and the rest will be borne by the municipal level. Taking the investment in education in Pujiang County in recent years as an example, the investment of 33.95 million yuan in sports field reconstruction is shared according to the ratio of 7: 3 between cities and counties. The 2 million yuan of funds for environmental transformation will be borne by the municipal level.

　　On the other hand, the financial allocation standard of public funds per student in Chengdu primary and secondary schools (including kindergartens and secondary vocational schools) was formulated, and the dynamic adjustment mechanism of public funds per student was established to continuously increase investment in rural education.

　　In Chengdu, the standard of public funds per student in compulsory education will be dynamically adjusted every two years, and a two-level joint guarantee mechanism will be implemented at the city and county levels. For the part of public funds per student that is higher than the national standard, the funds needed in the central city will be borne by each district, and those needed in the suburbs will be shared according to the ratio of 3: 7 between the city and the district, and those needed in the outer suburbs (cities) will be shared according to the ratio of 6: 4 between the city and the county (city). "May 12, For the standard of public funds per student in special education schools in the compulsory education stage, a system of annual adjustment and increase has also been established.

　　Pragmatic and flexible system design, "let money be spent on the cutting edge", has realized the optimal allocation of resources. Chengdu is creating a virtuous circle of "ecological circle". No matter the suburb or the outer suburb, no matter what level of schools, they can get the development needs, and generate has the opportunity and vitality.

　　Education thrives in cities, and cities are strong because of education — —

　　Education has become an inexhaustible motive force to promote urban development.

　　Running "primary schools" in universities and "universities" in primary schools is an important measure for Chengdu to continuously expand quality education resources and "build good schools at the doorstep of the masses".

　　In recent years, Chengdu has expanded high-quality resources through the development of prestigious school groups, school pairing assistance, entrusted management and the cultivation of "new high-quality schools", and achieved remarkable results. At the same time, it also faces the problem of "homogenization" and "simplification" to a certain extent, and it is urgent to further innovate the supply methods and paths of high-quality educational resources.

　　Looking at the educational map of Chengdu, the university where 64 is located is undoubtedly a "rich mine" to expand high-quality educational resources.

　　As far as Chengdu is concerned, relying on the resources of colleges and universities to speed up the cultivation and construction of a number of high-level basic education schools around colleges and universities is in line with the requirements of urban development pattern. The regional distribution of colleges and universities in Chengdu shows that the distribution of colleges and universities in Longquanyi District, Wenjiang District, Pidu District, Shuangliu District and Xinjin County in the near and outer suburbs of Chengdu accounts for 62.3%.

　　In 2018, the General Office of the Chengdu Municipal Government issued the Guiding Opinions on Promoting the Joint Construction of Affiliated Schools in Colleges and Universities, encouraging and supporting colleges and universities to rely on their disciplinary and professional advantages to cultivate the dominant disciplines in the joint construction of affiliated schools and form the characteristics of discipline teaching.

　　At present, Wuhou District of Chengdu, chenghua district, Sichuan University and University of Electronic Science and Technology have respectively formed new co-construction strategies for four affiliated schools. Shuangliu District, Longquanyi District and Xindu District have strengthened cooperation and established mechanisms with four resident universities, including Chengdu University of Information Technology, Sichuan Normal University, Chengdu University and Southwest Petroleum University, so as to realize the co-construction and sharing of pre-school to ordinary high school education, and preliminarily explore the embryonic form and different construction modes of the basic education development ecological circle around universities.

　　According to the plan, by 2020, Chengdu will also set up 15-20 new affiliated schools of colleges and universities through joint construction of schools and schools.

　　Meeting the people’s demand for higher-level and better-quality education is the "motive force" to create an "ecological circle around the development of basic education in colleges and universities", and it is also the initial intention to continuously "expand" the quality education resources and create an "excellent education Chengdu".

　　For this "initial heart", Chengdu continues to exert its strength:

　　— — Implement the "three-year attack" action plan for primary and secondary schools and kindergartens, and vigorously improve the level of education supply. In the past two years, 373 primary and secondary schools and kindergartens have been put into use, with 202,000 new places. Every year, more than 350,000 migrant children receive compulsory education, accounting for 70% of Sichuan Province.

　　— — We will continue to deepen reform, break through institutional barriers, optimize the system of "dynamic exchange" between principals and teachers, promote the "two-self-employment, independent management and lump-sum funding" reform, and continue to implement "big-handed" measures such as "county-managed school employment" in all districts and counties of the city to "loosen" and "empower" the development of primary and secondary schools.

　　— — Realizing the balance of quality education through educational informatization. In 2017, "Chengdu Digital School" was launched, combining information technologies such as the Internet, cloud computing and big data with the resources of famous schools and famous teachers in Chengdu, and creating a digital "borderless" school for primary and secondary school students in Chengdu at any time, anywhere and on demand, benefiting more than 1,500 schools in 22 districts (cities and counties) of the city. More and more students changed their fate through "one screen".

　　— — In 2019, Chengdu issued the "Opinions on Further Deepening the Development of Regional Education Alliance", focusing on promoting the development of regional education alliance to echo the new urban development pattern of "eastward, southward, westward, northward, and zhongyou", further breaking down regional barriers, management barriers, and ownership barriers to achieve high-quality development of education in Chengdu.

　　Adhering to the initial intention of "the city develops for the people" and practicing the new development concept, the grade of education development in Chengdu is getting higher and higher, and the road is getting wider and wider. (Reporter Huang Wei Lu Lei Ni Xiu correspondent Dong Zhiwen)

　　"The first batch of materials assisted by Jinan City arrived on December 20, all of which are tents, quilts, coats and other items urgently needed by the affected people. The second batch of materials will arrive soon." On December 23, Shan Xifeng, member of the Standing Committee of Jishishan County Committee and deputy head of Jishishan County, Jinan City, was busy receiving relief materials at the aid receiving point of Jishishan County, Linxia Prefecture, Gansu Province.

　　After the earthquake, nine members of Jinan Fire Rescue Detachment rushed to the front line at the first time. At the same time, Jinan Taihe Emergency Rescue Team carried materials worth 600,000 yuan and rushed to the front line of disaster relief.

　　The Lan Yonglin project undertaken by the 14th Bureau of China Railway, headquartered in Jinan, is about 42 kilometers away from the epicenter of Jishishan County. After the earthquake, the project personnel of China Railway 14th Bureau quickly raised materials to help the people affected by the earthquake, and coordinated large-scale operation equipment to clear rescue roads and build resettlement houses for the affected areas.

　　Jinan’s endless love assistance is gathering in Jishishan County.

　　"My teachers and I have now adjusted ourselves and systematically designed the recent teaching plan, looking forward to entering the learning state with you." On the morning of December 22nd, in the reception room of Jishi Middle School, President Dong Honghai gave the first lesson after the earthquake to the high school students in the county online.

　　Dong Honghai, 50, previously served as the vice principal of Jinan Middle School in Shandong Province. Last year, he participated in the national "group-style" education and came to Jishi Middle School to serve as the principal of the school.

　　After the earthquake, Dong Honghai and three teachers from the middle school affiliated to Shandong Normal University, Liu Wei, Qin Ran and Wang Han, rushed to the school at the first time to organize students to evacuate. With the joint efforts of all the teachers in the school, there were no casualties among nearly 2,000 students in the school. At present, three high schools in Jishishan County have carried out online teaching in classes.

　　Not only the education front, since the earthquake, Jinan City has been attached to the cadre team in Linxia Prefecture, and Jinan City has sent professional and technical personnel such as medical care, education and agricultural technology to Linxia Prefecture to invest in all fronts of earthquake relief and stick to their jobs. Twenty-five Jinan cadres stationed in Linxia Prefecture rushed to the epicenter area at the first time after the earthquake, and cooperated with local cadres to investigate damaged houses and trapped people from village to village, helping the people to evacuate, transfer and resettle in an orderly manner.

　　"After the earthquake, Jinan ‘ Group style ’ The members of the medical assistance team quickly returned to work. " Liu Lianzhong, the captain of the "group-type" medical assistance team, deputy secretary of the Party Committee and dean of Jishishan County People’s Hospital, said that the members of the Jinan medical assistance team have been sticking to their respective posts for five days since the earthquake. At present, there are more than 80 people injured in the epicenter admitted to Jishishan County People’s Hospital, and other patients have been discharged from the hospital or transferred to higher-level hospitals for treatment.

Majia Village, Liugou Township, Jishishan County is distributing aid materials from Jinan City.

　　"With the strong rear area of Jinan, we are not fighting alone." Shan Xifeng said that since the earthquake, he and the staff of Jinan City stationed in Jishishan County have received care and support from all aspects of Jinan. They will do their best to help the people in the disaster areas return to normal work and life as soon as possible.

　　Cross the mountains and seas and help each other. In Jinan, a steady stream of love assistance is gathering in Jishishan County, Linxia.

　　The responsible comrades of the counterpart support office of Jinan Development and Reform Commission said that with the end of the search and rescue work, the focus of follow-up material donation will be on children’s cotton-padded clothes, prefabricated houses and heating equipment. It is hoped that all walks of life in the city will continue to actively participate in the rescue activities for the people in the Jishishan disaster area to ensure the warmth of the people in the disaster area for the winter.

　　In the next step, Jinan will do a good job in helping Jishishan County to recover after the disaster, and at the same time, increase its efforts in industry, talents, labor services and social cooperation with Jishishan County, and constantly improve the level of cooperation between the two places. Qi Xin will work together to create an "upgraded version" of the cooperation between the east and the west.

　　CCTV News:The New York Times recently reported that American intelligence personnel are "stepping up efforts to implant malicious program code into Russian power system" in order to "spy on intelligence or launch cyber attacks on Russian power system". In this regard, Russian officials said on the 17th and 18th that the possibility that "the United States wants to launch a cyber war against Russia" does exist, and relevant Russian departments are constantly resisting such attacks.

　　Peskov, press secretary of Russian President, said on 17th that although the White House denied The New York Times’s report that "the US is trying to attack Russia’s power system by network", the possibility that "the US envisages launching a cyber war against Russia" does exist.

　　Peskov emphasized that Russia has repeatedly stated that Russia’s strategically important economic facilities "have been and are being attacked by overseas cyber attacks, and relevant Russian departments are constantly resisting such attacks to protect the economy and other sensitive areas from them" — — Russia has repeatedly suggested that international cooperation should be initiated to fight various forms of cybercrime with all parties, but the United States has never responded to this.

　　The Russian Ministry of Energy announced on the 17th that so far, they have not found that Russian power facilities have been attacked by overseas networks, and many Russian power companies are relying on domestic equipment and technology to eliminate the risk of overseas attacks step by step.

　　The Russian Ministry of Energy also said that most important power facilities in Russia have been connected to the national protection system, and Russian national information resources related to electricity are being protected by Russian professional institutions.

　　However, according to the Tass news agency, sergey Naryshkin, director of the Russian Foreign Intelligence Agency, said on the 18th that foreign intelligence agencies did try to invade Russia’s transportation, banking and power systems through the Internet, but Russia discovered these attempts in time and successfully foiled them.

Cctv news(Reporter: Xu Yeqing, Wang Jingyuan) On October 28th, the State Post Bureau held a special press conference on service guarantee in the peak season of express delivery business. According to Bian Zuodong, deputy director of the Market Supervision Department of the State Post Bureau, this year’s peak season covers 103 days from the beginning of November to the eve of the Spring Festival in 2021 (February 12). The peak of peak season will appear during the "double 11" period (from November 11th to 16th), and it is estimated that the daily average express delivery business volume will reach 490 million pieces, which is about twice the daily business volume.

"Crushing" the business volume of express delivery in North, Guangzhou, Shenzhen and Yiwu ranks first in the world.

According to the latest data from the Ministry of Transport, the average annual growth rate of express delivery business in China is over 30%, and the total volume and growth rate of express delivery business rank first in the world for five consecutive years. It is reported that in 2020, there will be nearly 60 express parcels per capita in China, which is about twice the global average.

The latest data from the State Post Bureau shows that 1-mdash; The city with the largest volume of express delivery business in September was not Beishangguangshen and Shenzhen, but Jinhua City, Zhejiang Province (with a total of over 5.9 billion pieces), ranking first in the world and one of the most concentrated foreign trade industrial belts in China. In addition, 1— In September, there were 10 cities with express delivery volume exceeding 1 billion pieces, which is the top ten cities in the list.

The courier is short of hands and has low income.

Over the years, the express delivery industry in China has maintained rapid development. In 2019, the national express delivery business volume exceeded 63.5 billion pieces, and the revenue growth rate of express delivery business was nearly four times that of the national GDP growth rate, and the express delivery business volume ranked first in the world for six consecutive years.

China Express Industry Social Contribution Report 2019 released by China Express Association shows that in 2019, the national express delivery enterprises served 350 million consumers on average, and the online retail sales of physical goods sent by express delivery exceeded 8.5 trillion yuan, accounting for 20.7% of the total retail sales of consumer goods in the whole society.

As express delivery has become an indispensable part of people’s lives, the market has created a huge demand for express delivery industry practitioners, but the number of couriers has been in short supply. According to the ranking of 100 jobs in short supply in the second quarter of 2020 released by the Ministry of Human Resources and Social Security on July 21, marketers, couriers and restaurant waiters have become the most short positions.

The shortage of couriers is not unrelated to their high-intensity work pressure. Previously, the "2019 National Professional Survey Report on Express Employees" (hereinafter referred to as the "Report") issued by China Post Express News Agency showed that express employees in China work 8-mdash every day; 46.85% of them work 10 hours a day. 12 hours accounted for 33.69%, and nearly 20% of employees worked for more than 12 hours.

According to relevant research, the shortage of couriers will exist for a long time to come. At present, the average daily delivery volume of express delivery in China is 250 million pieces. According to the current distribution efficiency, the gap of couriers will be around 1 million after 2021.

However, under such a high-load distribution pressure, the courier’s delivery cost is not optimistic. At present, the wages of couriers in China are usually piecework wages, which means that the wages earned are closely related to the quantity of pieces received and dispatched. According to the "Report", at present, the "Tongda Department" courier brother sends the most pieces per day. However, according to the latest financial report of Tongda Express Company, the receipt price of single ticket is generally higher in 2 yuan at present, which includes all the expenses of receipt, transit, trunk line and delivery.

According to the data of the State Post Bureau, although the express delivery business in Yiwu reached 5.972 billion pieces in the first three quarters of this year, ranking first in the country, the accumulated income of express delivery business in Yiwu in the first three quarters was 19.44 billion yuan, ranking only sixth in the country. Based on this calculation, the express delivery price in Yiwu is about 3.26 yuan/piece. In March of this year, some express scalpers in Yiwu even offered the price of "8 hairs nationwide".

On the one hand, the ever-increasing delivery volume of express delivery, on the other hand, the courier brother who is hard-working but short of manpower, once door-to-door service is difficult to fully guarantee, and the "last 100 meters" problem of express delivery needs to be solved urgently. Bian Zuodong said that at the peak of the peak season, the workload of couriers, especially delivery tasks, is often four or five times that of daily work. During the peak period, the express delivery time will be extended in some areas. Please be more tolerant of the express delivery time during the peak season, understand that the courier brother can’t deliver the goods upstairs as scheduled, and take more care of the tired courier brother.

There are various detailed explanations about the personalized recommendation algorithm of Netease Cloud Music on the Internet, but the official has never appeared! In order to solve users’ curiosity about the algorithm behind the daily recommended song list, we broke into the product and technology department of Netease Cloud Music Headquarters, held technical experts hostage, and spit out all our doubts.

This article is transferred from: The Power of Machines | Utoda

Old irons, do you know what day it is today?

Knowing that we should say happy holidays, we can’t forget to wait for the singles assigned by the state in the cold kennel.(as if I wasn’t talking about myself).

This morning, when I found that the dog food scattered by my circle of friends had been enough for one year, I still turned on Netease Cloud Music, trying to find the same kind in the lively comment area: another group of single dog people.

Unexpectedly, in addition to a "special interview for the first year of singles", the first song recommended to me every day turned out to be:

The Best Day of My LifeBest day of my life.

……

Well, the lyrics "I won’t give up on myself, don’t wake me up, this is the best day of my life", which makes me seriously doubt that the personality recommendation of Netease Cloud Music has penetrated the normal life of all single dog users:

"Don’t always stay in the comment area, please find your own happiness before coming next year. Otherwise, as soon as the Year of the Dog is over, your title will become’ single pig’. "

Happy Valentine’s Day and Happy Year of the Dog.

On the Zhihu, two questions, "What is the song list recommendation algorithm of Netease Cloud Music" and "What’s good about Netease Cloud Music", occupy the third and eighth place in the hot topic of Netease Cloud Music respectively.

To a large extent, the first question has made the second question.

Perhaps Netease Cloud Music has a variety of reasons for its one-sided praise on Zhihu.Some people say that they have hired a large number of water forces. If so, it should be a heavy investment. I won’t tell you that the communities of the two platforms overlap greatly)However, the quality of the song list is hard, and the personality recommendation is relatively accurate compared with the domestic competing products, which is one of the key reasons for some users to develop into Netease Cloud Music diehard fans.

And, the first question can also explain why you will see a lot of comments such as "Japanese push first", "Japanese push second" and "Japanese push +FM simultaneous recommendation" in the comment area of many songs.

However, it is not very appropriate for some people to compare Netease Cloud Music to "a paradise for independent and minority music lovers". Re-exposing those songs that have been ignored by the public to your eyes is often the role of technology behind the scenes.

Just like you downloaded a song from Jay Chou today, will the system push you another popular song with a similar style in Jay Chou the next day, or push an unpopular song with a similar style, which will make you feel more novel?

There is some truth in this answer.

However, it is a bit surprising. Netease Cloud Music has never officially disclosed its recommendation algorithm and product application details. But this does not prevent the public from being interested in the process of integrating their technology and products.

Therefore, the algorithm model and AI application in Netease Cloud Music have basically been ripped apart by Zhihu users.

You can find a great answer and speculation in the Zhihu topic "What is the song list recommendation algorithm of Netease Cloud Music?"(The high praise answer in it is not too clear than the media reports, and it is easy to understand.).

The reason why we want to visit Xu Jia, a data mining engineer and product manager of Netease Cloud Music, is not so much to uncover the secret of the algorithm as to verify it before.(including on the Internet)All kinds of guesses, as well as help users answer the doubts arising from the use of Netease cloud music.

Basic algorithm: people are divided into groups

In fact, the personalized recommendation algorithm of Netease Cloud Music is similar to the basic recommendation algorithm applied in today’s headlines, station B and many O2O e-commerce platforms. This has been certified by the Xu family, which is the kind of basic algorithm we are familiar with:

This algorithm is attributed to the invention of Amazon engineers-if a customer buys this thing, he may also buy another thing.

Simply put,The prediction standard of this algorithm depends on the similar consumption patterns between people.For example, I like these two songs, and they are also in your song list, so there may be other songs I like in your song list.

The above statement is only easy to understand.In fact, collaborative filtering algorithms should be divided into two categories: user-based and project-based (single).

1. Based on users:I have a high similarity with Xiao Ming’s collection of songs, so on the basis of judging that our tastes are similar, I can recommend Xiao Ming the singles in my collection that she hasn’t collected.

Image source: data mining workers

2, based on the project (single):That is, the user’s preference for a song is used as a vector to calculate the similarity between singles. After comparing the similarity, we recommend a single to another user according to this user’s historical preference.

For example, Xiao Xin downloaded two singles, Courage and Little Love Song, while Xiao Yi downloaded Courage, Darkness and Little Love Song, while Xiao Yi downloaded Courage …

According to the historical preferences of these users, Netease Cloud Music can judge that Courage is similar to Little Love Song, and those who like Courage may also like Little Love Song, so they can recommend Little Love Song to Xiaoyi.

Image source: data mining workers

In short, if you still find it difficult to understand the algorithm of "collaborative filtering", you can just remember one word: people are divided into groups.

It’s a crooked building here: it is this recommendation model, which is essentially based on the similarity of users’ preferences, that invisibly makes users form a community of "chatting with each other" while listening to music.

Therefore, Shen Bowen did not regard "it may develop into the largest dating website in China in the future" as a nonsense joke. Instead, I think that this social trend based on music preferences is more reliable than the current dating platform:

Curiosity Daily has done a survey before. What are the main reference standards for human beings to find their soul mates? -it’s music taste.

"Birds of a feather flock together" under the neural network model

It can be seen that this recommendation algorithm is absolutely indispensable to the support of user historical data. Collaborative filtering algorithm is very powerful when the amount of data is huge and clean enough.

On the other hand, if I am a new user, or I use Netease Cloud Music very infrequently. In other words, in the case of scarce data, how can Netease Cloud Music know my taste?

This cold start problem means the inevitability of cross-use of different algorithm models. Perhaps the following second category of algorithms can eliminate this obstacle to some extent.

• Content-based recommendation algorithm.

This is a recommendation method that focuses on distinguishing the essence of single content, and it is regarded as "birds of a feather flock together".

Sander Dieleman, one of the founders of Spotify content recommendation model, a world-famous music streaming platform.(now a DeepMind research scientist)In a blog post titled "The Application of Convolutional Neural Network in Music Recommendation", I specifically explained the errors when using a single collaborative filtering algorithm:

1. Because this algorithm not only includes the information of users and consumption patterns,There is no information about the recommended single itself. Therefore, popular music is easier to be recommended than unpopular music because the former has more data. And this kind of recommendation is often hard to surprise.

2. Based on collaborative filtering of items (single songs),There is also a problem, that is, the content heterogeneity under similar usage patterns.

For example, if you listen to all the songs in a new album, but except the title song, other episodes, covers and remixes may not be typical works of singers, then collaborative filtering will be biased because of these "noises" at this time.

of course，Its biggest problem is that "without data, everything is invalid".

Therefore, the content-based recommendation algorithm is more like a supplement to the above shortcomings of collaborative filtering algorithm-if there is not a lot of user data, or if we want to listen to unpopular songs, we can only find the answer from the music itself.

Two experts, Xu Jia and Shen Bowen, made it clear that Netease Cloud Music adopted a complex content-based algorithm to solve these problems. But unfortunately, the two did not explain the specific details too much.

Therefore,According to our guess, they should use the same method as streaming media platforms such as Spotify and Youtube-using deep learning to build audio-based recommendation models..

First of all, if you want to compare the content differences between singles, there are too many dimensions, such as artist and album information, lyrics, melody and rhythm of music itself, boasting in the comment area, VIP downloading songs, paying or not, and so on.

As you can imagine, this is a huge amount of calculation. But calculating the total amount of violence is a method …

Therefore, so many features should be mapped into the low-dimensional hidden variable space by feature embedding and dimensionality reduction methods.(Like the picture below).

It is conceivable that in this space, each song can have a coordinate, and the coordinate value is multiple coded information including audio characteristics and user preferences.

Then, if we directly predict the exact position of a song in this low-dimensional space, it will also clarify the representation of this song.(including user preference information).

In this way, it can be recommended to the right audience without historical usage data.

Therefore, it is a way that many streaming media are taking to master the hidden characteristics mapped from a large number of song data sources and user behavior data, and then establish a neural network prediction model based on audio characteristics and train the network with short audio clips. (The specific method can be to look through Sander Dieleman’s paper. If you know this, tell us a lesson! )

Of course, in the process of training the network, engineers will still pass the "discard"（Dropout）And other methods to reduce the standard deviation between the hidden representation of filtering model and audio prediction.(Don’t let the data set be too discrete)And this is mainly to reduce the influence of song popularity on the recommendation system.

That’s right, that’s why you can receive more minority song recommendations.

Of course, any of the above algorithms will actually be based on a certain "similarity".

For example, Netease Cloud Music also applies the machine learning ranking model, which is still based on user behavior data and similarity.(It is also a very common model).

Reflected in the application, in popular terms, the first song in your "Daily Recommended" song list is usually the one that the system thinks matches your preferences the most. "Many people often shout’ Day Push First’ in the comment area, and its significance is still quite great."

In Zhihu, there is a recommendation model "Potential Factor Matrix" mentioned by Big V, but Xu Jiaze thinks it is out of date, and few people use it now.

Calculation method-how do we calculate the similarity of our song list?

According to the Xu family, Netease Cloud Music mainly uses two measurement methods:

Euclidean distance and cosine similarity.

The blog of a technical expert in CDSN has explained the difference between them very clearly.(below)：

From the CDSN technology blog named Ying.

The former is regarded as two points in the coordinate system to calculate the distance between the two points.

For example, when data A and B in the above figure are regarded as points in the coordinate diagram, their similarity is the absolute distance dist between two points.(A,B).

The latter is regarded as two vectors in the coordinate system to calculate the included angle between the two vectors.

For example, cosθ in the figure, the smaller the included angle, the higher the similarity.

You will find that, still on this picture, if the position of B remains unchanged and the position of point A continues to extend in the opposite direction of the line from A to the origin, the cosine angle between A and B will remain unchanged forever, but the absolute distance between the two points has changed.

This difference makes them need to be used in different data analysis models.

Xu explained that Euclidean distance, which can highlight the absolute difference of numerical values, is often used in calculating the similarity of songs themselves.

For example, 10,000 people like A songs and 20,000 people like B songs. Because the sample size is large enough, all users’ preferences for songs can be regarded as the same intensity, then the European distance can be directly used to calculate.

Under the European distance, users’ preferences for songs can all be considered as the same score, which can simplify the calculation of song similarity.

The cosine similarity is more about distinguishing differences from the user’s preference direction.

For example, Netease Cloud Music can use this method to rate content through users.(There are different scoring weights such as download, collection, search and uninterested)To distinguish the similarity of users’ interests.

In short, combining the above algorithms and calculation methods, Netease Cloud Music’s personality recommendation has a good reputation among the public.

But this kind of "not bad", if it can be achieved only by technology, I am afraid that Amazon’s business in China will not be so bad(I’m actually voicing its interface).

Frankly speaking, even the best algorithm has its shortcomings.

For all music products, the score of user experience is composed of editing and project collaboration, interface design preferences, music copyright richness, music preference prediction, technical ability and problem feedback speed.

This is why some people are crazy about calling for the recommended song list of Netease Cloud Music, and many people say that "people who listen to miscellaneous songs may be really tired of using Netease Cloud Music".

For example, you are a loyal fan of European and American music circles, but you have downloaded a Chinese song occasionally recently.

Then I can be sure that there will be a Chinese song in your recommended song list the next day. Next, I can only be "uninterested" in the Chinese songs that appear in the song list.

The recommendation algorithm sets the weight based on different users’ behaviors, with "download" being the highest, followed by collection, search and sharing. In addition, you can also click "not interested", which may avoid such songs.

In addition to algorithm recommendation, to a great extent, a streaming media platform will also assume the responsibility of manual filtering, establish manual rules from the perspective of products and operations, and filter out unqualified options.

Shen Bowen told us that they don’t just rely on the algorithm, but hope to compensate some shortcomings of the algorithm through some artificial power.

Therefore, in addition to a separate algorithm team, Netease Cloud Music also has a strong editorial team.

On the one hand,They help to do a layer of screening on the recommended content at the beginning, find out those high-quality content, and ensure the health of the whole recommendation library.

On the other hand,They also need to solve some convergence problems of the algorithm.

"Because if we rely solely on algorithm recommendation, we may be slow to respond to some new content, and we will also use some manual editing methods. To find out some content that we may think is very high quality, and then recommend it to everyone, "Shen Bowen said.

In addition, even if the customer service system relies on AI technology to a certain extent, the "artificial feedback group" composed of Netease Cloud Music customer service department and technical department is an important reason for users to have a good impression on Netease Cloud Music.

Many "second-back" technical solutions have also been dubbed by users as "the original Xiaobian of Netease Cloud Music is really alive".

In the early stage of platform development, when the data volume can’t meet the requirement of establishing recommendation algorithm model, as an Internet author named Shaq in Zhihu described:

The reason why you can get the high-force recommendation is probably that it first came from a song list recommended by a professional editor named "High-force Small Fresh".

They effectively guided users with similar interests to discover these music. Most people who have similar tastes with you have heard them and felt good. After fancy’s algorithm, they "precipitated" and "fermented", and then produced a good similarity, thus generating such an excellent recommendation and pushing it to you.

Finally, everyone was "amazing" and more new users joined, Perfect.

In the past weekend, Shenzhen welcomed the third wanda plaza.

On July 30th, Guangming wanda plaza officially opened. In the first two days of opening, this small shopping center is almost crowded with people-people need to queue up to show the green code, buy snacks, even take the escalator, and the event host and security personnel constantly remind people to wear masks.

As a matter of fact, this wanda plaza is not only the latest opening in Shenzhen, but also the smallest wanda plaza. Can it continue to maintain a large passenger flow after the excitement of opening?

Guangming wanda plaza is located on the side of Exit C and D of Fenghuang Station of Metro Line 6, and the subway entrance is directly connected, which can transform the flow of people brought by the subway.

Wanda plaza is a centralized business with Yuefu Plaza. The two parties signed a cooperation in 2019, and it was the first wanda plaza to settle in Shenzhen, which attracted a lot of attention in that year. The commercial area of the project is only about 45,000 square meters. The commercial part consists of 4 floors above ground and 1 floor underground, and it has a certain outdoor area, but in general, it is not large.

According to official data of Guangming wanda plaza, the project has assembled 113 brands.

According to the observation of the interface building, the project is mainly based on the brand stores at the mass level. In addition to the Wanda Studios, the clothing brands include ochirly, Jordan, Warrior and Hailan House. Jewelry brands include Lukfook Jewelry, Laofengxiang, Leofoo, etc. Mobile phone numbers include Huawei and OPPO. Although the number of brands is small, the basic retail types are relatively complete, and we have a Xingqin supermarket.

In terms of catering, there are chain brands such as Xiaolongkan, Xiabu Xiabu, Bahui, Shunyi, Saizeriya and Yidengdeng, as well as chain beverage brands such as Ruixing, Naixue and Starbucks.

It is worth noting that there are three new energy automobile brands here, including FAW-Volkswagen’s pure electric space, BYD, and zero-run cars. This concentration is rare in the shopping malls outside the customs.

In addition, although the volume is small, some "first stores" are also welcomed here, such as the first TEEBOX flagship store in South China and the first store in JOY MARK Shenzhen.

During the opening period, there were "million group purchases", "50% discount for gourmet merchants", "50% discount for seasonal clothes" and "the highest gold is reduced by 120 yuan", so most shops were crowded. Moreover, there was also the "Bright First Street Culture Festival" two days after its opening, which brought a series of activities such as flash mob, street basketball and fancy skateboarding.

According to the official data of the project, within two days of opening, the passenger flow was 250,000, and the sales exceeded 22 million yuan. At the same time, there are 12 national crown-selling stores and 50 whole-body crown-selling stores, and the average daily sales of 35 brands have exceeded 100,000 yuan.

Looking back, when wanda plaza was born 20 years ago and settled in about 200 cities in China, the first wanda plaza began to settle in Shenzhen.

In November 2020, Bao ‘an wanda plaza opened. However, as the first wanda plaza in Shenzhen, Baoan wanda plaza is not satisfactory. On the one hand, this wanda plaza is not close to the subway station, and it takes more than 20 minutes to walk from the nearest subway station, so the traffic is inconvenient; On the other hand, although it has a volume of 100,000 square meters, the internal structure and design of this wanda plaza are old and unattractive because of renting the venue of Fucheng Jiazhou Business Center.

By September, 2021, Longgang wanda plaza also opened for operation, and it is also the largest wanda plaza in Shenzhen, reaching 300,000 square meters.

Longgang wanda plaza is also the "fourth generation wanda plaza", so it is also concerned by the outside world. Inside the shopping center, there are ladders, giant screen eyes, floating planets, "the world’s longest indoor glass plank road" and other landscapes from the first floor to the sixth floor, and great attention is paid to creating an interactive experience with customers. It is reported that the interactive experience format is over 80%, and the retail format is less than 20%.

Bright wanda plaza also opened ten months later, but it didn’t have many "titles" and a small size. With youth culture as the carrier, it gathered the consumer demand of "Generation Z", so it introduced Chaowan Club and JOY MARK brands when it opened.

Horizontally, bright wanda plaza can attract a large number of passengers, which is not unrelated to its location. There are many emerging communities around Phoenix, such as Dragon Light and Nine Dragons Terrace, Shenfang Chuanqi Mountain, Guangming Dadi, etc., and many families have gathered.

In addition, just at Exit A and Exit B of Phoenix Station, that is, across the road from Guangming wanda plaza, there is the Blue Whale World with a dragon body volume of 100,000 square meters.

Blue Whale World opened in December, 2021. By contrast, it has a larger volume, more brands and a higher brand level, and wanda plaza has little advantage. However, because the distance between them is very close, it will form a business circle and increase its appeal to people.

At present, in addition to the above two shopping centers, Guangming also has centralized businesses such as Daqianli, Gongming over the rainbow Shopping Mall, kk park Guangming Square and Qinchengda K+ Square. Among them, the largest volume is Daqianli, reaching 150,000 square meters, followed by 100,000 square meters of the Blue Whale World.

Now, the Blue Whale World, together with wanda plaza, has formed a business circle with a volume of nearly 150,000 square meters, which will undoubtedly compete with Daqili and become another bright and popular business circle.
