Summer Economy | Night shopping, night entertainment, night travel … Which cities love "nightlife" best?

In the evening of summer, the business circle of the city is gradually becoming lively, and "shopping" and "shopping" have become "necessary" items in summer nights. In recent years, "nightlife" is expanding from catering and shopping to entertainment and leisure, and night cultural activities such as performances and exhibitions are gradually increasing.
Night shopping, night eating, night practice, night reading, night entertainment, night outing … The prosperity of "night economy" is an important symbol of a city’s economic openness and activity. Since the beginning of this year, many places have proposed to develop the night economy, and local government officials have taken the lead in taking to the streets to eat supper, and many places have issued documents to promote the vitality of night consumption.
In the hot summer, how can cities ignite "fireworks" in 2022? What are the new trends of night economy under the boost of local consumption policies? Which cities love "nightlife" best? Who is the main force of night consumption? The Beijing News Shell Finance takes you through the data to see the "consumption picture" of midsummer night.
1.2022Economic scale is expected to break through.40Trillion yuan
Which cities are"The city that never sleeps"?
Night economy is an important part of urban economy, and it is also an important starting point for cities to stimulate consumption.
According to the survey report of urban residents’ consumption habits of the Ministry of Commerce, 60% of residents’ consumption occurs at night, and young people born after 1995 are the main group of night economy.
2019 is called "the first year of night economy in China", and the night economy develops rapidly. The State Council issued "Opinions on Accelerating the Development of Circulation to Promote Commercial Consumption", proposing to enliven night businesses and markets and improve the convenience and activity of night consumption. In 2019, the night economy reached 26.4 trillion yuan, a year-on-year increase of 15.3%. In the following two years, the night economic growth rate exceeded 17%. According to Ai Media Consulting, China’s nighttime economic growth rate will continue to grow in 2022, and the economic scale is expected to exceed 40 trillion yuan.
In 2021, the Ministry of Culture and Tourism announced the first batch of 120 national night cultural and tourism consumption gathering areas. The data shows that Beijing, Hebei, Shanghai, Jiangsu, Zhejiang, Jiangxi, Shandong, Guangxi, Chongqing and Sichuan have the largest number of night culture and tourism consumption areas. Qianmen Street in Dongcheng District of Beijing, Tianqiao Performing Arts Zone in Xicheng District, 798-751 Art Block in Chaoyang District, Liangmahe Style Waterfront in Chaoyang District, Huaxi LIVE· Wukesong in Haidian District and Gubei Water Town in Miyun District are all on the list.
Night economic agglomeration has become the common carrier of night economic construction in most cities. Guangzhou, Beijing, Shanghai, Qingdao, Suzhou, Foshan and Kunming have clearly put forward relevant construction plans. For example, Foshan proposes to build eight high-quality night economic clusters by the end of 2021, and Kunming proposes to build 15-20 night economic clusters.
In order to boost the economy and consumption vitality, measures to develop night economy have been issued in many places this year.
The Beijing News Shell Finance reporter found that taking Beijing as an example, in February 2022, the Beijing Municipal Bureau of Commerce and other 10 departments issued "Several Measures for Further Promoting the Development of Business Circle", which put forward 14 specific measures to promote the development of business circle from four aspects: innovating business circle management mode, creating a prosperous and standardized business circle consumption environment, improving the intelligence level of business circle and increasing policy support, among which "encouraging key business circles to develop night economy" became an important content.
Henan proposes to focus on the development of "night economy", allowing the use of "shops outside" and "open-air markets" under standardized and orderly conditions. In Xi ‘an, qualified commercial pedestrian streets and commercial complexes are allowed to operate outside in the specified time period at night, and outdoor activities such as automobile market, cultural and creative market, cultural performances and night trips to Chang ‘an are held based on characteristic commercial districts.
This summer, the "trunk market" rose again, enriching the nightlife consumption scene.
In Nanjing, Qingdao and other cities, whenever night falls, many people drive their cars to the local square, line them up in turn, open the trunk to display goods, install small light bulbs and literary signs, and turn them into miniature shops. Such a "trunk shop" has attracted many citizens to stop.
Generally speaking, China’s night economy presents the characteristics of "strong in the south and weak in the north". According to the big data of the ride, during the period from May 1 to June 20, 2022, among the TOP 10 cities with night travel activity, 9 cities in the south and only one city in Beijing in the north. Among them, the top five cities in activity belong to South China.
In addition, the demand for night travel also reflects the economic vitality of the city, and the demand for night travel of residents in new first-tier cities is generally more. The Beijing News Shell Finance reporter found that among the top ten cities traveling at night, there are 5 new first-tier cities, 3 first-tier cities and 2 second-tier cities. In 2021, the GDP trillion club, New Jincheng, Dongguan ranked third, and Foshan ranked fourth.
It is worth mentioning that second-tier coastal cities are also active at night. Two second-tier cities, Xiamen and Quanzhou, ranked in the top ten for night trips, and Xiamen ranked second, second only to Shenzhen.
2."at nightDrink "into a young man"New consumption trend
exceedsixsucceedInterviewedConsumers go at least once a month.
On summer nights, having a drink with three or five friends has become one of the ways for young people to relax at night.
Urban nightlife scenes are constantly enriched, and pubs that are mainly open at night have become an important scene for people to socialize and entertain. According to the sample survey of Ai Media Consulting, more than 60% of the consumers interviewed go at least once a month, among which 27.5% go once every two to three weeks and 18.9% go once a month.
Although drinking is the main thing, unlike nightclubs, the bistro with a sense of atmosphere provides more social space and is a "compound" venue that includes music, board games, performances and catering.
Night consumer demand is constantly released, and the pub economy is growing steadily.
In 2018, the scale of China’s tavern market exceeded 100 billion yuan; In 2021, the market scale reached 128.04 billion yuan, an increase of 26.2% compared with 2020. Zheshang Securities said that with the relaxation of epidemic prevention and control policies in various places and the peak of night consumption in summer, the demand for night consumption has been steadily restored, which is expected to promote the concentrated outbreak of pub format in summer.
The pub economy is hot, more people are eyeing this "cake", and many catering enterprises have entered the "bistro" across the border. According to Ai Media Consulting, from 2015 to 2020, the total registered volume of China tavern-related enterprises showed an overall upward trend, with a compound annual growth rate of 49.5%. By the end of 2021, the total registered volume of related enterprises reached 14,658. Among them, there are many new consumer brands like Naixue, as well as catering enterprises such as Puju and Laoxiang Chicken.
3. DuodiExtend the opening hours of cultural venues such as museums.
Cultural life enters night economy.
In addition to catering and shopping, the cultural consumption of night life is also increasingly prosperous. Many places propose to extend the opening hours of museums, art galleries and other cultural venues, and visiting museums and watching exhibitions has also become a favorite night cultural activity for consumers.
The rise of night cultural activities has promoted the gradual recovery of China’s performance market.
In 2021, the overall scale of China’s performance market reached 33.585 billion yuan, an increase of 27.76% compared with 2020. Among them, drama has become the most popular type of performance. In 2021, among the 114,400 theatrical performances, the box office revenue of drama performances ranked first, and the number of drama performances ranked third.
On June 29th, Ma Li, deputy director of the Industrial Development Department of the Ministry of Culture and Tourism of China, said that the Ministry of Culture and Tourism would plan and implement an action plan to promote cultural and tourism consumption in the second half of the year, seize the peak summer consumption season, focus on developing night culture and tourism economy, and guide relevant institutions to publish night culture and tourism consumption maps.
4.E-commerce night market "helps night economy"
Which cities like to place orders at night?
Liu Genghong, who escaped the aerobics this summer, did not escape Dong Yuhui, who brought goods in the live broadcast room of Oriental Zhenpin.
Since June this year, the bilingual live broadcast of New Oriental has been on fire, which not only allows people to see the new way of live broadcast with goods, but also allows people to see the potential of e-commerce night market economy.
With the maturity of new consumption patterns such as live e-commerce, the proportion of online sales channels shopping at night is expanding. Ningbo, Shanghai and other places issue e-commerce coupons to stimulate consumption. On June 27th, Anhui started the night economic consumption season, focusing on key sectors such as automobiles, home appliances, catering and e-commerce, to help the whole chain of consumption recover.
The data shows that people in first-tier cities prefer to place orders online on summer nights. From May to June 20, 2022, the number of online shopping orders in first-tier cities ranked in the top four, and Beijing ranked first. Chengdu, which is called "the city that never sleeps" by many tourists, is also enthusiastic about online shopping.
What do people who don’t sleep buy? Residents in different areas have regional characteristics in shopping. Consumers in Changsha and Hangzhou, online celebrity’s tourist cities, prefer travel products, while residents in Fuzhou and Guangzhou prefer entertainment products. People in Sichuan and Chongqing prefer food and drinks, while Beijing and Shanghai prefer fresh food.

2023 Oriental Beauty Valley International Cosmetics Conference opens. How can China’s beauty industry break?

"Oriental Beauty Valley China Characteristic Cosmetic Raw Material Base Alliance" was unveiled. The pictures in this article are all provided by the organizers.

The 6th China International Import Expo is in full swing, and the international top event of cosmetics industry is also on schedule.

On the morning of November 9, 2023 Oriental Beauty Valley International Cosmetics Conference officially opened. This conference is the sixth, with the theme of "Beautiful World of Oriental Beauty Valley", and many well-known enterprises, experts, scholars and industry leaders from home and abroad gathered together.

As the "capital of cosmetics industry in China", Oriental Beauty Valley has gathered more than one third of cosmetics enterprises in Shanghai, with an industrial scale of nearly 100 billion yuan. According to the "2023 Oriental Meigu Trademark Brand Value Evaluation Report" released at the opening ceremony, the trademark brand value of Oriental Meigu has reached 33.878 billion yuan, with a total increase of 312% in the past five years.

Release the blue book on the spot

Post-80s and post-90s become the main consumer groups of high-quality cosmetics.

According to the "Blue Book of Oriental Beauty Valley 2023" released at the opening ceremony, the cosmetics market in China will usher in a new round of rapid growth in 2023. In the first half of this year, the total retail sales of cosmetics market reached 207.1 billion yuan, up 8.6% year-on-year.

The blue book shows that consumers tend to pay extra premium for high-quality products, among which the post-80 s and post-95 s are the main consumer groups. More than 80% of consumers are willing to spend money because cosmetics can provide high emotional value (improve the quality of life and happiness). At the same time, consumers’ purchasing decision-making process is becoming more rational.

In terms of product cognition, the resonance between ingredients, raw materials and R&D is pushing the beauty industry to turn to biotechnology, and the beauty market has entered the raw material bonus period, and the China raw materials of domestic beauty cosmetics are also widely loved. The olfactory economy is on the rise, and perfume brands have laid out the field of care. Green and safe sustainable beauty cosmetics are leading the new trend of health and beauty.

With the local online live broadcast and offline shopping malls showing the Red Sea trend, local cosmetics enterprises have shown an urgent incremental demand for going out to sea.

Football physical fitness: how do I maintain my physical fitness during the season?

Hello, everyone, today we share how I keep fit during the season. I hope you like it!

front cover

In 2020, Joshua kimmich scored the winner in the match with Dortmund. In that match, he ran 13.73 kilometers. This is the sport of football and kicking. In this sport, most of the running is not jogging, sprinting, walking, jogging and then sprinting. Because of this, the best way to improve physical fitness is to carry out high-intensity training.

We can achieve this goal by sprinting or intermittent training, but the least boring way to improve physical fitness is to use the ball for high-intensity training, which is also the focus of today. Today we will share the training methods to keep in shape during the season. Let’s officially start:

warm up

Before we start training, make sure that we have fully warmed up, do some dynamic stretching and sprinting, so that all our fast muscles will be activated, thus reducing the risk of muscle strain. Take 10 minutes to relax, and then start formal training.

Figure 1- Warm up

This is the only part that does not include the ball, and it is one of the very good agility and quick training.

We can find a friend, or install an application on our mobile phone, which can flash colors and numbers for us for 10 times as a group. I

Figure 2- Fast Move on Command

When our cell phones flash or our friends shout out a color, we sprint to the sign plate and then go back to the middle. About 30 seconds, depending on the length of the interval. In short, do five groups and rest for 30 seconds between each group.

Figure 3- Gap Time

The rest of the training is divided into three small cycles. The first cycle is what we see now. Before Ronaldinho’s dribbling training and shooting, he makes a 30-yard sprint dribble.

Figure 4- Fast Dribble

This training is great, because it can train our dribbling speed, dribble in a narrow space, and persist in dribbling when we are tired.

Figure 5- Exercise dribbling speed

It’s a hard training, but it’s important for us to keep high shooting quality. Imagine that we will be very tired in the 80th minute of the game, so even if we are tired, we should be able to shoot correctly.

Figure 6- Correct Shooting

In this cycle exercise, we can jog or walk back to the starting point as a break between repeated exercises.

If we only have one or two balls, run after them, make sure we are jogging, then jog back to the starting point, and then give yourself an extra 30 seconds to rest.

Figure 7- Jogging or Walking

In addition, because it takes a long time to start each action, you should do it for 15 minutes before continuing this circular action, and it should be very fast.

Before entering the second cycle, give yourself three to five minutes to rest. We should make sure that each cycle has intensity, and even if we are tired, we should work 100%.

Figure 8- Guaranteed Strength

In the second cycle, we make 10 passes to the wall, then zigzag dribble to practice turning and dribbling, then rush out and beat the last sign plate with one of our actions.

Figure 9- Passing the ball to the wall

Put the sign plate 8 to 10 yards away, make sure we don’t go straight through it, rush out of the sign plate for at least a few steps, then cut back the sign plate and walk back to the starting point.

Figure 10- Switch back the sign plate

Once again, this is our break time, and a sign plate is set for passing the ball on the wall to ensure that we keep good habits when passing the ball and that we will not be lazy.

This cycle improves our ability to pass, touch the ball with the first foot, dribble and cut inside with the ball, and the ability of all 1V1 to beat the defender.

All this will make our leg muscles stronger, and at the same time enhance our heart and lung function. Do it for 10 minutes, and then rest for three to five minutes before continuing.

Figure 11- Cardiopulmonary Enhancement

Figure 11- Cardiopulmonary Enhancement

The hardest part was left to the end. Many people hated doing this exercise, but it was the simplest exercise, and it was timed in 10 minutes.

Start by running back and forth, run to the small restricted area and then run to the penalty spot at the back, then run to the top of the restricted area and come back.

Figure 12- Simple exercise

After the round-trip run, start bouncing the ball as soon as possible, don’t rest for a few seconds before starting, and then bounce the ball 30 times before starting the next round-trip run.

Figure 13- Start the ball.

The key point here is that if we screw up and drop the ball, then we need to start the next round trip immediately, which puts pressure on the ball-passing part to ensure that we concentrate on the ball-passing and strive to maintain the quality.

If we don’t have this kind of pressure, then we will drop a few times, then pick up the ball on foot, and then continue to bounce the ball and give ourselves a long rest. After 10 minutes, we have finished the hardest part, but we are not completely finished.

Figure 14- No End

Although this is not the main part of training, it is very important to do 5 to 10 minutes of cold-body exercise, which will make our muscles less tense and help us recover from the next training.

Figure 15- Let the muscles loose.

Don’t skip this link, do some static stretching or the same dynamic movement as before, but with less intensity.

Figure 16- Don’t try to hide from the tiger

That’s all for today. Please continue to pay attention to the road of football for more exciting football teaching!

Global artificial intelligence competitiveness, the United States first, South Korea seventh, China ranked?

On March 12th, the Korean media Caijing Today published an article saying that some analysts said that South Korea’s AI (artificial intelligence) competitiveness ranked seventh in the world. The United States ranks first in the world.

According to the "The Global AI Index" of British data analysis media Tortoise Intelligence, the AI competitiveness of the United States ranks first. The analysis target is 62 countries.

The scores of the United States are: 86.19 for implementation, 100 for innovation and 88.69 for investment. Totus Intelligence converted the scores of various fields in the United States into a comprehensive score of 100, and scored other countries as a standard.

In second place is China. China scored 69.36 points for implementation, 75.69 points for innovation and 69.44 points for investment, with a comprehensive score of 62.92 points. Ranked third to sixth are Britain (40.93 points), Canada (40.19 points), Israel (38.89 points) and Singapore (38.67 points).

South Korea ranked seventh (38.6 points). The scores of each field are: 56.21 points for implementation, 51.95 points for innovation and 46.45 points for investment. In terms of specific projects, South Korea scored high in government strategy (87.5 points) and infrastructure (85.2 points). However, it ranks lower in commercial projects (5.4 points) and talents (14.5 points).

Ranked 8th to 10th are the Netherlands (36.35 points), Germany (36.04 points) and France (34.42 points). In addition, Japan and India ranked 16th (30.53 points) and 17th (30.36 points) respectively.

Epic CEO: Commercial AI should not use works for training without the author’s permission.

Epic Games is not only the game and technology, but also the parent company of ArtStation, a platform for hosting commercial artists’ works. In a recent interview, Tim sweeney, CEO of Epic Games, said that he hoped the company would strike a balance between the protection of works of art and the participation of creators in new technologies such as AI image generation.

A few months ago, ArtStation created a label called "noAI" because of the protests of many artists, and the tagged works will be banned from being used by the AI system on its platform.

Sweeney said: "We support many game developers. Some of them will use artificial intelligence, and some people will hate artificial intelligence. We hope to be a reliable neutral intermediary that does not hinder the development of the industry, but we will not deliberately collect data on everyone’s works. "

During the interview, he also explained that if it is for commercial use, the AI system should never use their works without the unification of artists.

He added: "They grab people’s works of art on the Internet and then use it without their explicit consent."

"A company should not do such a thing, right? Maybe it is within the scope of research and study (no problem), but when you sell it for making commercial works of art and commercial products, you should not do so. "

The core technology of "making the brain" serves the important needs of the country

In today’s world, the level of human science and technology has reached an unprecedented height. With the entry into the intelligent era, a new round of scientific and technological and industrial revolution characterized by the deep integration of information technology and manufacturing industry has flourished, and technical groups in many fields have broken through and merged, which has promoted profound changes in manufacturing production methods. Countries all over the world have taken a series of major measures, hoping to rely on the manufacturing revolution with intelligent manufacturing as the core, consolidate the foundation of innovation and development of manufacturing industry, and build new kinetic energy and new advantages. As a manufacturing power in the world, China has listed intelligent manufacturing as the main direction determined by Made in China 2025, which is not only the key to promote the transformation and upgrading of China’s manufacturing industry, but also an important strategy to become a manufacturing power in the world.

Professor Song Xuan from the Department of Computer Science and Engineering in south university of science and technology of china, whose main research direction is artificial intelligence and its related fields, including big data analysis, data mining and urban computing, has applied the research results to disaster emergency and epidemic prevention of major infectious diseases, and achieved good results. At present, in the series of research in the field of intelligent manufacturing, it contributes scientific research strength to promote the development of intelligent manufacturing in China and accelerate the pace of building a manufacturing power in China.

Intelligent analysis of data model is committed to tackling the key core technology of "intelligent brain"

Since 2013, China’s development strategy has specifically pointed out that "the country’s strength depends on the real economy and cannot be bubbled" and "the innovation-driven development strategy is deeply implemented to enhance the core competitiveness of industry". "Made in China 2025" clearly emphasizes the need to accelerate the integration and development of a new generation of information technology and manufacturing technology, and take intelligent manufacturing as the main direction of deep integration of the two; Efforts will be made to develop intelligent equipment and products, promote the intellectualization of production processes, cultivate new production methods, and comprehensively improve the intelligent level of R&D, production, management and service of enterprises. Intelligent manufacturing can effectively improve the production efficiency of manufacturing industry, shorten the product development cycle and reduce the defective rate of products, which is the key to building a digital China, realizing "Made in China 2025" and breaking the chip blockade.

The national science and technology strategy points out that "it is necessary to cultivate a large-scale team of young scientific and technological talents, focus on the policy of cultivating the strength of national strategic talents, and support young talents to take the lead and play the leading role." As a young scientist born in 1980s, Professor Song Xuan is currently presiding over the national key R&D project "Multi-dimensional data space and service theory of manufacturing product life cycle value chain". The project focuses on the key technology of "manufacturing brain", which is the key theoretical model and technical method of tackling the problem, and provides technical support for the intelligent upgrading of high-end manufacturing industries (such as automobile manufacturing) in China.

Professor Song Xuan said that there are some problems in the process of data storage and analysis in manufacturing industry, such as chaotic data interface, inefficient storage, low level of intelligence and opaque information, which affect the quality of product collaboration and data value-added in manufacturing industry and are not conducive to the sustainable development of manufacturing intelligence. In view of this situation, the project puts forward a set of multidimensional data space and service theory of manufacturing product life cycle value chain, which integrates data sharing and integration and data analysis service. The multi-dimensional collaborative data space prototype model theory of product life cycle value chain based on blockchain proposed by this project can guide safe and efficient data sharing and assist product R&D collaboration; The data analysis method based on deep learning and knowledge generation technology proposed by the project can realize causal inference, speed up the traceability of problems and shorten the product development cycle. Taking intelligent manufacturing as an opportunity and the actual upgrading demand of manufacturing industry as a guide, the project focuses on the two cores of "manufacturing brain": data flow and intelligent analysis, which is of great significance for China’s manufacturing industry to build a competitive advantage in the industrial chain and further improve the intelligent level of manufacturing industry. The project also puts forward a set of multi-dimensional data space and service theory of manufacturing product life cycle value chain, which integrates data sharing and integration and data analysis service.

Professor Song Xuan believes that intelligent manufacturing needs a "manufacturing brain", and manufacturing data is the "blood" of "manufacturing brain"; Algorithm models such as deep neural network are the main part of "manufacturing brain" and play the role of thinking and decision-making; Data flow is collected in the "manufacturing brain", which can automatically complete data analysis, intelligent decision-making and product life cycle prediction and deduction, and realize efficient intelligent manufacturing. The theory of multi-dimensional collaborative data space prototype model of product life cycle value chain based on blockchain proposed by Song Xuan can guide safe and efficient data sharing and assist product R&D collaboration. The data analysis method based on deep learning and knowledge generation technology proposed by the project can realize causal inference, speed up the traceability of problems, shorten the product development cycle, and predict and simulate the product life cycle.

Building an urban brain platform and focusing on building a smart city

From December 2019 to December 2022, with the liberalization of the epidemic, the pneumonia epidemic in Covid-19, which lasted for three years, finally came to an end, and the epidemic situation was gradually controlled. In this epidemic prevention and control, Professor Song Xuan led the project team to develop the "novel coronavirus (Covid-19) communication modeling, prediction and simulation deduction platform driven by human flow big data and AI", which played an important role. Based on artificial intelligence (AI) technology, the model of potential infection sources and risk areas was mined on the city scale, and the communication modeling, prediction and simulation deduction platform for COVID-19 was built. For the big data analysis and AI modeling platform for novel coronavirus communication, the prediction and simulation deduction model was complete. Made outstanding contributions to the prevention and control of the epidemic.

In addition, Professor Song Xuan, as the project leader, has developed an "epidemic prevention chain" APP on the mobile device side. The APP on the mobile phone side can assess the risk of epidemic or major infectious diseases (such as new crown pneumonia, seasonal influenza, etc.) in real time by sensing the contact between users and others and analyzing various urban environmental big data (such as crowd density, air quality, environmental humidity and temperature, etc.).

In fact, as early as 2011, the big data analysis and modeling of people flow carried out by Song Xuan’s team contributed to the fight against viruses and natural disasters. In March 2011, after the earthquake in Japan and the Fukushima nuclear accident broke out, Song Xuan led the team to develop a number of emergency flow prediction models and a system to help the Japanese government analyze the evacuation and migration of victims after the disaster and formulate more efficient post-disaster reconstruction policies. In 2016, in response to the Ebola outbreak in West Africa, the research of Song Xuan’s team helped the International Telecommunication Union to analyze the flow of people in West Africa and the spread and infection of Ebola virus, which played an important role in the prevention and control of Ebola virus.

Professor Song Xuan has been deeply involved in the field of artificial intelligence for 15 years. He deeply realized that the main place for modern people to live and work is the city, and the core of urban management is to make people’s life in the city safer, more comfortable and more convenient. With the proposal of building a smart city, Song Xuan now pays attention to urban data and tries to alleviate or solve various "urban diseases" such as traffic congestion, environmental pollution and natural disasters. His team realized the simulation and prediction of the large-scale movement of urban people by building a modeling model of urban mass people movement, thus realizing efficient urban intelligent management. Song Xuan is currently tackling key problems and building an urban brain platform, bringing together all aspects of urban informatization and the whole process of urban management through high and new technologies to carry out control and support, so as to ensure travel safety, give full play to the efficiency of urban infrastructure, improve the operational efficiency of transportation system and the level of urban governance, alleviate all kinds of "urban diseases" to the greatest extent, and help urban governance to be more scientific, refined and intelligent.

"Scientific research should always serve the public" is precisely with such a sense of mission and responsibility. In the future scientific research, Song Xuan will always focus on his mission, aim high and live up to his youth, take data as the core and science and technology as the weapon, and strive to build an intelligent brain, help build a smart city and build an intelligent manufacturing power.
