foreword

"Green wave belt is a concept that has existed in the transportation industry for a long time. Daily interaction relies on its long-term technical accumulation in big data and artificial intelligence. By fusing and calculating its own data, traffic control department data and third-party data, it integrates cycle time, surrounding scenes, road traffic direction, driving speed and other factors. The algorithm is used to calculate the best signal and control parameters, quickly form an urban green wave scheme, and can be dynamically adjusted according to the real-time traffic flow and road conditions on the road. In the case of having as little impact on the surrounding traffic as possible and making maximum use of the existing transportation infrastructure, the complexity of green wave signal control coordination and optimization is greatly reduced, allowing the traffic control department to dispatch and manage the traffic flow of the road network with a click of the mouse, so that "Photoshop" can be turned into "Meitu Xiuxiu" in seconds. At the same time, it helps the urban traffic control department to build a digital traffic management system at a very low cost, and quickly improves the fine and intelligent water of urban road traffic signal control. Realize "100 times efficiency" with "100% rate", help the construction of a transportation power, and create a safe, orderly, smooth and civilized road traffic environment for the masses to travel. "

Special thanks to the Hangzhou traffic police. Hangzhou is the first city where our number of smart green waves have landed. It is also under the trust and professional guidance of the Hangzhou traffic police that we have really polished this product and continuously optimized it. Since October last year, we have co-created and strengthened the construction of green wave belts with the traffic police brigades of Hangzhou districts, changing the original mode of setting up long-distance green wave belts, turning 3-5 intersections into a group, turning lines into faces, and increasing the speed by about 20%. At present, there are more than 200 green wave belts built in Hangzhou, with a mileage of more than 300 kilometers, all over the urban area of Hangzhou. In their daily travel, Hangzhou citizens have unknowingly enjoyed the smooth convenience brought by the green wave belt.

Yesterday, Fang Yi, founder and CEO of Daily Interactive, accepted Love’s analysis and systematically shared his views and successful practices on urban traffic congestion management.

01 Urban traffic congestion management is the world’s most prominent problem in urban diseases, and daily interactions seek new breakthroughs in solutions

Love Analysis: Big report, we need to speed up the construction of a transportation power and figures, and improve urban water governance. Traffic congestion, as the most prominent and most global problem in "urban diseases", is very realistic and challenging to manage. At present, what are the common painpoints in the traffic control department in optimizing urban road condition management and serving citizens’ travel?

Fang Yi: Big, to accelerate the construction of a transportation power and digital, the Ministry of Transport and the Ministry of Science and Technology have also jointly issued the "Opinions on Accelerating the Construction of a Transportation Power Driven by Scientific and Technological Innovation" and the Outline of the Medium and Long-term Development Plan for Scientific and Technological Innovation in the Transportation Field (2021-2035). The development of the strategy and related policies has provided a good policy environment for the development of our data intelligence field and pointed out the development direction.

During the "14th Five-Year Plan" period, our country’s economy will transition to high-quality development, and the volume of passenger and freight transportation will continue to grow. The main problems facing transportation governance are poor traffic flow in the core areas of cities and insufficient smart transportation coordination. According to official statistics, the number of cars in 70 cities in our country has exceeded 1 million. Traffic congestion is the most common, most frequent, most prominent and most world-wide problem in urban diseases, and its governance is very realistic and challenging. According to field observations and industry exchanges, we found that the current traffic control departments generally have the following pain points in optimizing urban road condition management and serving citizens’ travel:

First of all, the number of urban cars in our country, the number of drivers surged, the urban population continues to increase, traffic facilities gradually complex, but the city’s intersections, road sections of the digital construction is still not high, the lack of intelligent traffic coordination, data sharing system has not yet formed, resulting in the city’s overall road conditions online monitoring and analysis is difficult, single point intersection timing intelligent low, many intersections often empty or congestion phenomenon.

At the same time, traffic control departments are mostly based on manual experience, lack of big data support, and the effect of intersection signal timing after manual adjustment cannot be quickly and accurately verified. Closed-loop iterative optimization is difficult to achieve, and there is a lack of sufficient coordination between different intersections and regions. It is difficult to cope with the complex traffic conditions that change in real time throughout the region. Unreasonable single-point green signal ratio settings will have a significant impact on the traffic efficiency of intersections.

At present, many cities commonly use Australia’s SCATS (Sydney Coordinated Adaptive Traffic System) and Europe’s SCOOT (Split Cycle Offset Optimizing Technique) system, its timing capabilities, adaptive capabilities, although very powerful, but data collection through urban roads coil or geomagnetic induction to achieve, its ground sensing equipment is often due to urban road planning adjustment, perennial traffic flow and frequent damage failure, and SCATS and SCOOT system is not "intelligent", timing personnel need "code level" ability, through the input of complex code scripts for timing, the use of high threshold, and the system for traffic police repeated temporary adjustment without "memory ability", it is difficult to precipitate experience, the formation of "reuse", can not flexibly respond to the ever-changing urban traffic conditions.

Finally, the investment in transportation infrastructure in various cities is huge, with hundreds of thousands of intersections at every turn. It is difficult to get through the data of different suppliers. The cost of "one game of chess" transportation intelligence in the entire city and region is high, and the hardware investment is large and the effectiveness is small.

In view of the above situation and pain points, Daily Interactive hopes to use cutting-edge technologies to assist in the innovation of traffic management concepts, management methods, and management models, and to improve the modernization, informatization, and intelligent water of traffic governance. This year, Daily Interactive has created a "Digital Smart Green Wave" product (hereinafter referred to as "Digital Smart Green Wave") for the field of smart transportation. This product can help the traffic police department to efficiently complete the intelligent timing of signal lights and the intelligent coordination and optimization of green wave routes, and realize the digital construction and intelligent scheduling management of road network traffic flow, better serve citizens’ travel, and improve the traffic management water in various cities.

In early 2022, Wenzhou City, Zhejiang Province plans to build (Wenzhou) Data Intelligence and Security Service Innovation Park (ie "Shu’an Port"). Daily Interactive has been deeply involved in it in the early days. When Shu’an Port is completed and operated, "Smart Transportation" happens to be released as Scenario 001. We hope that by relying on the establishment of Shu’an Port, we can make full use of our massive and vivid mobile Internet big data and capabilities, and deeply integrate multi-party dynamic data from traffic management departments, map service providers, and third-party data intelligence service providers for joint calculation, build a localized business system, and provide traffic management tools for traffic control departments to carry out intelligent application in the field of smart transportation.

Love Analysis: Compared with the traffic lights and manually coordinated green wave belt solutions of the traditional timing scheme, what innovations and breakthroughs have been made in solving the above pain points of the traffic control department by the "digital intelligence green wave" advocated by Daily Interactive?

Fang Yi: The so-called green wave belt is not a new concept, but a concept that has existed in the field of transportation for a long time. It refers to the fact that on a designated traffic line, when a vehicle travels at a specified speed, the signal controller adjusts the green light start time of each intersection that the traffic flow passes through according to the distance of the road section, so as to ensure that when the traffic reaches each intersection, it just encounters the "green light", thereby improving the overall traffic efficiency of the traffic line.

Our "digital intelligence green wave" product will use big data intelligent means to analyze the comprehensive traffic flow at intersections, optimize the single-point green signal ratio, improve the utilization efficiency of intersections under large traffic flow, and screen out the traffic arterial intersections suitable for the construction of green wave belts. By considering factors such as cycle time, surrounding scenes, road traffic direction, and driving speed, the algorithm is used to calculate the best signal and control parameters, increase the green wave coordination control, and ensure the smooth passage of vehicles on regional arterial roads by accurately segmenting the timing of intersection signals, thereby reducing delays and stopping times, and achieving the goal of "stop at most once".

The biggest feature of the daily interactive "Digital Intelligence Green Wave" product is to connect and connect the data layer, and conduct data mining and analysis of traffic scenes such as traffic flow distribution, signal control characteristics, intersections and road characteristics, providing traffic distribution, green wave recommendation, green wave optimization and other service components, and then support specific operations such as intersection/road network visualization configuration and intersection coordination relationship research and judgment in specific traffic management applications, so as to achieve "data characterization, feature serviceization, and service application", allowing urban traffic control departments to analyze, respond to, and monitor road conditions in real time, especially for traffic police to quickly and dynamically adjust the timing of intersection lights under their jurisdiction according to real-time road conditions.

Compared with the traditional timing scheme, the "digital intelligence green wave" product can be quickly optimized according to the traffic flow data of the road surface, rather than the "fixed" scheme under the traditional timing, which is more practical and flexible; compared with the manually coordinated green wave scheme, the "digital intelligence green wave" product is supported by traffic flow data and intelligent algorithms, reducing the heavy dependence on expert experience, and the operation is simpler. There is no need for the front-line traffic police to master complex codes. After only one hour of simple training, the front-line traffic police can master the system proficiently, and can realize the one-click configuration of the green wave scheme. It can also be used to fine-tune single intersections and road sections by dragging and dragging. At the same time, digital intelligence green wave can be based on the overall coordination and control of the entire region to avoid the overall inefficiency of regional traffic caused by the lack of systematic thinking and local optimization of various intersections and road sections.

02 Daily interactive "Digital Intelligence Green Wave" products help urban transportation upgrade from "manual transmission" to "automatic transmission"

Love Analysis: What is the general working principle of the "Digital Intelligence Green Wave" product? During this process, what core resources and technical capabilities have been mobilized by Daily Interaction to ensure the intelligence, efficiency and safety of the "Digital Intelligence Green Wave" product?

Fang Yi: Our "Digital Intelligence Green Wave" product, combined with Internet big data, provides personalized green wave signal control solutions in time periods, and conducts regular monitoring of green wave road sections, and makes decision-making and timing for green wave solutions that meet requirements, so as to realize the digitalization of road network traffic flow and intelligent scheduling management. Specifically, it can be understood from the following aspects:

Figure: Schematic of the solution architecture of the daily interactive "digital intelligence green wave"

Our "Digital Intelligence Green Wave" product uses big data joint computing as the underlying infrastructure to maximize the security of data flow computing. This is because, although the massive data of daily interaction is given to the system at the statistical level under the green scene, which fully complies with the requirements of the Personal Information Protection Law, Data Security Law and other relevant regulations, it also needs to integrate the data of the traffic control department and even third parties. Therefore, it needs to enter the private network through the border and integrate the data in the private network for computing to provide services for upper-level applications. In order to ensure product and data security, all the data are put on the state-owned big data joint calculation for joint calculation, to ensure that the original data source can enter and exit, can be counted and not recognized, can not be used, the algorithm is transparent and easy to supervise, and the calculation is safe and efficient.

In terms of basic capabilities, Digital Intelligence Green Wave connects with rich data sources, and uses a powerful system inside Daily Interactive – "DiOS Data Intelligent Operating System" for data governance and fusion calculation, generating signal control scheme suggestions. We use our own big data to perceive real-time traffic flow data on the road, and at the same time, under the coordination of the traffic control department, we will also access the traffic control department’s road network basic data (such as traffic lights, lane lines, etc.), traffic police business data, infrastructure sensing data, etc. for fusion calculation and cross-validation. In the future, it may even be integrated with more third-party maps and data from travel service providers, so that the traffic control department can make a more three-dimensional judgment on traffic flow and road conditions. So how do we manage and calculate so many sources of complex data? This requires the use of the DiOS data intelligent operating system. DiOS can fully mobilize the company’s core capabilities in digital modeling, security computing, visual intelligence, intelligent transportation, etc., perform fusion calculations on the basis of data governance of all parties, and "scene" all kinds of traffic data. It is used to analyze and mine the traffic flow characteristics and travel OD characteristics of various intersections, road sections, and regions, so as to generate corresponding signal control scheme suggestions, and provide simulation components to facilitate the simulation and prediction of the effects of different signal control schemes.

In terms of business applications and empower, our digital intelligence green wave is connected with SCATS and other systems through API and RPA, so as to carry out real-time transmission and execution of signal control solutions and support automatic delivery. At the same time, based on the regional and road network traffic characteristic data, the daily interaction provides functional modules such as road network housekeeper, signal control optimization, green wave, cockpit, operation monitoring, etc., which can perceive, analyze, and dynamically adjust and optimize the information control measures of the road network. Based on the above functional modules, the urban traffic control department can easily implement three-dimensional business applications such as macro-urban planning suggestions to mid-scale road network construction guidance and digital intelligence green wave services through self-filtering maps, green wave design, program delivery, effect prediction and optimization.

It is worth mentioning that the digital intelligence green wave can also carry out the overall coordination and system optimization of regional traffic in a "game of chess" style. In order to avoid the green wave belt in a certain direction destroying the traffic efficiency of the road crossing it, when the horizontal road is made into a green wave belt, our "digital intelligence green wave" product supports a traffic light intersection as the center, and all intersections in the area are aligned with it, so that the intersecting routes and directions can be matched into green wave belts to carry out the overall optimization of regional traffic "game of chess". Of course, traffic is impermanent, and traffic flow is constantly changing in real time. Therefore, the digital intelligence green wave must have the ability to respond to emergencies and continuously iterate and optimize. In the actual traffic management process, it is not realistic to pursue green lights at all intersections. Here, the traffic control department needs to make value judgments. In order to prevent the situation of "snakehead biting snake tail", Digital Intelligence Green Wave also supports "temporary solutions". Once a temporary emergency such as a traffic accident occurs at an intersection or road section, the signal light control can be quickly restored to the original state. When the temporary emergency is over, it can be restored to the green wave state, thereby eliminating traffic pressure. In addition, Digital Intelligence Green Wave can also use technologies such as short-term flow forecasting and variable lanes to make intelligent iterations of the green wave solution and build a closed-loop urban traffic management business.

Finally, it comes to the specific use level. One of the major advantages of our digital intelligence green wave products is the ease of use. The horizontal axis is a road, and the vertical axis is the time axis. When the left signal light phase is selected, the right signal light phase can be automatically aligned with one button. Through this relative alignment, the regional green wave band scheme can be quickly realized. With the assistance of the machine, the difficult "photoshop" can be changed into "Meitu Xiuxiu" in seconds, which greatly reduces the complexity of green wave signal control coordination and optimization, allowing the traffic control department to dispatch and manage road network traffic flow with a click of the mouse.

Love Analysis: What are the core values of "Digital Intelligence Green Wave" products for urban traffic management and people’s livelihood? What kind of cities and road sections are they mainly suitable for?

Fang Yi: From the working principle above, you can see that our "Digital Intelligence Green Wave" product is based on the Internet-side big data fusion calculation, and builds urban green wave belts at a very low cost to help urban traffic control departments build digital traffic management systems, perceive and analyze road profiles in real time, and provide rational construction suggestions to quickly improve the fine and intelligent control of urban road traffic signals, creating a safe, orderly, smooth and civilized road traffic environment for the masses to travel.

It is worth mentioning that our "Digital Intelligence Green Wave" product does not waste any sensors, but makes maximum use of the existing existing facilities and aggregates the data together to achieve "cross-domain data fusion" to provide mutual verification for the urban traffic control department. For example, in case of some extreme situations, the daily interactive traffic flow data changes rapidly, and the traffic control department can use its own data to calibrate the daily interactive traffic flow data; similarly, the daily interaction can also infer the unreasonable traffic facilities data of the traffic control department, and then complete it.

Figure: The main advantages of the daily interactive "Digital Intelligence Green Wave" product

From the perspective of the scope of application, as long as it is a road section that has realized online control, it has the application basis of "digital intelligent green wave". At the same time, the daily interactive "digital intelligent green wave" product has its own set of metrics, such as the repetition rate of the number of vehicles entering a certain intersection and leaving the intersection, etc. We will make a comprehensive judgment based on the location of the road section and surrounding facilities. For example, we find that a road section is equivalent to a tunnel, and the repetition rate of cars entering and leaving is very high. Then we consider this road section to be a commuter road and suitable for green wave belts.

Love Analysis: It is understood that the daily interactive "Digital Intelligent Green Wave" products have been launched in Hangzhou, Wenzhou, Huzhou and other cities, and have received good feedback. So, can you systematically introduce the company’s construction ideas when helping urban traffic control departments implement the "Digital Intelligent Green Wave" project?

Fang Yi: From a physical perspective, the construction ideas of our Digital Intelligence Green Wave project can be divided into the following steps to achieve a closed loop from concept communication, diagnosis, design planning to scheme optimization and solidification.

The first is the concept submission. We will first throw out our understanding of urban traffic management, fully discuss with the traffic control department, and promote the two sides to reach an agreement on the concept; then, we will clarify the daily interaction based on the underlying data to empower the front-end business with intelligent algorithms, emphasizing the traffic control department, especially the front-line traffic police as the user experience, from the traditional industrial control field thinking mode to the Internet-oriented C-end thinking mode, improve the ease of use of the front end, and do not need to change any of the original urban traffic construction plan, which can be completed at a very low cost.

The second step is to start planning and design. The daily interactive "Digital Intelligence Green Wave" product uses the data of mobile Internet big data, traffic police departments and map service providers to automatically jointly calculate and generate roads suitable for green wave construction in cities, and supports manual intervention of recommended green wave road sections, which can be added, deleted and modified according to the actual situation. For example, in the Hangzhou Green Wave Belt project, we found more than 700 kilometers of roads suitable for green wave construction in Hangzhou based on our own measurement standards, and submitted their distribution map to the Hangzhou traffic control department for review and discussion.

The next step is to configure the green wave. Digital Intelligence Green Wave can combine road network data and data such as the speed and flow of corresponding road sections and intersections to intelligently recommend a number of road sections that are most suitable for the construction of the green wave belt, and calculate detailed green wave configuration plans to assist in the final green wave belt construction decision. The traffic police department can select specific road sections for the "green wave scheme" effect experience according to our recommendation results. Then, we use visual intersection stewards to achieve comprehensive input and visual display of green wave construction information such as signal infrastructure, channelization, and flow; at the same time, the road network stewards will integrate information such as road section length, historical vehicle speed, and road section characteristics to generate intelligent recommended vehicle speeds, providing speed guidance for the design of the green wave scheme and ensuring the green wave effect.

Next is the division of time periods and scheme design. Speaking of which, we have to mention the great advantage of our smart green wave products that are easy to use. Smart green wave supports the adjustment and optimization of green wave bands by simple dragging on the time and distance diagram. It can be adjusted individually according to different scenarios (schools, scenic spots), different time periods (morning, evening peaks, daytime peaks), different periods (working days, weekends), etc., and multiple green wave scheme designs for specific intersections and road sections can be carried out. The optimal green wave scheme can also be selected according to the monitoring data and control experience of the traffic control department on specific road sections.

Single-point optimization is also very valuable. In this link, we can combine intersection flow data, intersection characteristic data and intersection signal control data, and accurately optimize the single-point signal control scheme of all intersections in the area to produce a single-point recommended timing scheme divided by time period, which can be automatically or manually issued, or sent to the signal light control system after manual intervention of the single-point recommended timing scheme.

Finally, to the practice running and program optimization, solidification link. We will assist the traffic control department to optimize the overall and single-point green wave scheme in the selected road section for partial or comprehensive practice running, and real-time operation monitoring of the program effect, according to the actual regional, road network program application and then optimized, submitted to the city traffic control department for confirmation, so as to achieve the solidification of the green wave scheme for different intersections and different time periods.

Figure: Daily interactive intelligent green wave belt construction idea schematic

In addition, from the perspective of specific service methods, the daily interactive "digital intelligence green wave" project construction process includes four steps of pilot mode, deployment, product use training, and product optimization and upgrading. During the pilot period, the daily interaction can provide some selected road sections of green wave belt construction and promise corresponding results, providing free training and free product iteration and upgrade services during the maintenance period.

Love Analysis: Can urban transportation be graded with reference to autonomous driving? What is the significance of this in helping smart city governance upgrade?

Fang Yi: Just as autonomous driving can be divided into five levels according to the degree of autonomy from "fully manual to fully automated", we believe that the degree of digital intelligence in urban traffic can also be graded according to the degree of intelligence in the control of traffic lights at various intersections in the city. Therefore, we have developed the "Smart Transportation 6L" classification concept.

Figure: Daily interactive "Smart Transportation 6L" grading concept

Level L1 means that there are signal lights at the intersection, which can be used for basic traffic control. Level L2 means that the signal lights at the intersection are connected to the Internet, and the traffic police can issue instructions remotely for single-point regulation. Level L3 is based on L2, and can perceive digital information such as the queue length and speed at the intersection through radar, cameras, geomagnetism and other equipment installed at the intersection, as well as big data on the Internet. Level L4 can analyze and model the data uploaded at the intersection to form a dynamic, data-guided closed-loop control. Level L5 is based on L4 to realize intelligent coordination of multiple intersections, such as the construction of "digital intelligence green wave belt". Level L6 is to achieve intelligent road management and control, that is, based on data modeling and analysis of regional road characteristics, business districts, schools, etc., it can achieve fine coordinated control of multiple intersections and comprehensively improve regional road functions.

The development process and scale of cities in our country vary greatly, and the investment progress of transportation infrastructure varies widely. Even in some relatively developed cities in the south, a large number of signal lights in the city may still be single-point level and have not been networked. Through the "Smart Transportation 6L" grading concept, the daily interaction can be based on the same language and measurement system with local traffic control departments to help cities find the specific coordinates of different intersections and road sections, and combine the urban transportation construction plan and budget of the year to communicate the upgrade plan of different intersections and road sections, such as upgrading from L1 to L2, or directly skipping to L3. At the same time, based on the agreed upgrade path, the daily interaction can complete the intelligent upgrade of urban transportation facilities at designated intersections and road sections within a certain period of time as agreed, and cooperate with cities to flexibly arrange the upgrade progress. This can greatly reduce the pressure on fiscal expenditure in each year, making the intelligent upgrade of urban transportation visible, controllable, and low-cost. It is expected that the daily interactive "digital intelligence green wave" products will initially be centered on the Yangtze River Delta and then rolled out nationwide.

03 Daily Interaction empowers domestic traffic intelligence with data intelligence core capabilities

Love Analysis: What are the plans for daily interaction in the future in terms of digitalization and intelligent upgrading in the field of transportation?

Fang Yi: In the field of transportation, we mainly have the following two aspects of planning:

In terms of urban transportation, as mentioned earlier, daily interaction will use big data in a very convenient way to achieve initial intelligence of urban transportation. The current is the "smart green wave" solution, and in the future, daily interaction will also use Wi-Fi sensing systems or other new road condition sensing systems in a more refined way, coupled with big data to close the loop, greatly reducing the construction cost of intelligent urban transportation.

In terms of high-speed transportation, Daily Interactive is currently cooperating deeply with Zhejiang Gaoxin Technology joint stock company, a subsidiary of Zhejiang Jiaotong Investment, to help it further deepen its expressway informatization business with DiOS data intelligent operating system; at the same time, Daily Interactive also uses its own technical capabilities to create an early warning system for abnormal situations on expressways, and actively participates in the management of abnormal situations such as highway throwing. Specifically, we use the high-speed "gantry" ETC data to calculate the instantaneous speed of each vehicle entering and leaving and the interval speed between the two gantries, and according to the speed and traffic flow changes between the gantries, combined with expressway cameras, quickly find problems on specific sections of the expressway and give timely warnings to reduce the risk of expressway accidents. At present, the early warning system for abnormal conditions on expressways has been able to detect abnormal sections in about one and a half to two minutes, and inform the expressway traffic police two to ten minutes before the accident so that they can arrive at the abnormal section in advance and quickly for processing. In the future, the daily interaction will further dig into the management scene of high-speed traffic, and continue to work hard to improve the informatization of expressways and reduce the accident rate of expressways.

Love Analysis: What other perspectives do you want to share on road network digitalization, urban transportation governance, and other aspects?

Fang Yi: Now there is a new trend in traffic governance to apply radar and video, but the cost and edge computing cost of this solution are relatively high. In recent years, our domestic computing resources have been greatly improved, but the computing power is ultimately limited, and the rational use of computing power resources has become the key to reducing costs and increasing efficiency. I think that many vehicles, especially new energy vehicles, are constantly emitting various wireless signals such as Bluetooth and Wi-Fi. If traffic management departments build wireless signals to build sensing devices above the ground rather than underground to manage traffic, the difficulty and cost will be much lower, and it will become a new paradigm.

"Digital Intelligence Green Wave" is the result of daily interaction and innovation for people’s livelihood needs. With the general trend of accelerating the construction of a transportation power, a network power, and digital, we are on the road of data intelligence at the right time, hoping to drive more social changes with data intelligence in the future.

As of press time, the intraday share price was HK$ 15.90 per share.

　　In the past few days, many departments have repeatedly issued announcements prohibiting any form of wildlife trading. Many places have also isolated places for raising and breeding wild animals. However, according to the first financial reporter, there are still loopholes in "refusing to eat game".

　　A number of people in the industry reported to the First Financial Reporter that over the years, wild animal bodies such as fox meat, mink meat and raccoon meat from farms have been sent to slaughterhouses or small workshops to be processed into roast sausages or ham sausages. In some professional journals, there are even experts who guide how to process the meat of these wild animals into delicious food and sell it on the market.

　　Secrets in the industry?

　　Changli County, Hebei Province has nearly 30 years of fox, raccoon dog and mink breeding foundation, and the fur industry has become a local characteristic industry. The total number of breeding remains at around 8 million, accounting for one tenth of the country, and the total output of raccoon dogs ranks first in the country.

　　Changli County is also the largest fur trade center in China, with an annual trade of 15 million fur and 500,000 live animals, with an annual output value of 8 billion to 10 billion yuan. Changli County was awarded the title of "China fur industry base" and "China raccoon dog breeding hometown" by the Specialty Society of China Agricultural Society. The county has formed a complete industrial chain of mink and raccoon breeding, improved seed breeding, feed and veterinary drugs, commerce, processing and logistics.

　　When the first financial reporter interviewed in the local area, a person in charge of a farm said: "Some people bought fur and some people wanted meat, and sent it to the meat joint factory." When the reporter asked further, the other party seemed a little nervous and just said, "This is a secret that everyone in the industry knows."

　　A person in charge of a group farm in Hebei told the First Financial Reporter that each raccoon skin can be sold around 500 yuan, and the breeding cost of each raccoon is about 200 yuan, and the benefits are still good. However, if there is a problem in the breeding process, the quality of the leather is not good, and some people do not make money.

　　Bad leather does not affect the sale of meat.

　　According to public reports, in June 2014, the Food and Agricultural Products Testing Center of Shandong Inspection and Quarantine Bureau showed the mutton products containing fox meat and mink meat detected by the center.

　　On a food investment website, the first financial reporter also inquired that mink meat and raccoon meat were for sale. The wholesale price of raccoon meat is 2.2 yuan per kilogram, which is far lower than the price of pork and beef.

A food business network sells information about mink meat and related meat grinding equipment.

　　There is even a medical science popularization WeChat official account who issued a document saying, "For 2 yuan, if you want to eat beef sausage or pork sausage, it is basically impossible." "A more formal manufacturer will use chicken. Generally, the main ingredients are chicken breasts, chicken skin and duck skin, and then the main flavoring substances — — Pork essence, monascus red pigment, preservative, and filler starch to reduce cost. Some manufacturers may use fox meat, mink meat and so on. Because these meats come from farms, as long as the farms are fur, the meat is generally free. "

　　On a professional website containing various academic journals, the First Financial Reporter inquired about many papers such as Development and Utilization of Raccoon Meat, Development of Cumin Raccoon Meat Enema, Study on Comprehensive Utilization of Raccoon Byproducts: Utilization of Raccoon Carcass Meat, etc.

　　Among them, it is mentioned that "raccoon dogs are an important wild animal resource in northeast China, and in recent years, there are many artificial breeding in various places." "Most wild animal farms, after slaughtering and skinning, some smash raccoon meat as feed for fur animals, some dispose of it at a very cheap price, or even discard it", and "processing it into food can create higher profits for farms (households)".

　　Some experts instructed in the paper that "because the carcass of raccoon dogs is small, it is not easy to be removed, and the meat of raccoon dogs has a slightly earthy smell, so it is made of ‘ Braised canned food ’ The process, and pay attention to adding condiments that can remove the earthy smell in the formula to improve the flavor and palatability of the product. " "In order to eliminate the odor of raccoon meat and improve its edibility, ‘ Spicy Sichuan sausage ’ The formula and its technology, the main processing steps include thawing-cleaning-removing tendons, connective tissues and fat-cutting into small pieces-soaking in clear water-mincing-seasoning-pickling-canning-steaming-smoking, etc. "

　　Some experts in the industry have also calculated that the average raw material cost per kilogram of sausage is 5.98 yuan. If it is sold at 10 yuan/kg, the gross profit per kilogram can be 4.02 yuan. If 10,000 raccoon dog carcasses are processed every year, 14,737 kilograms of spicy Sichuan sausage can be produced, and the gross profit can be more than 59,000 yuan, with considerable benefits.

　　There are hidden dangers in the wild animal meat in the farm.

　　Are wild animal carcasses such as mink meat and raccoon meat from farms safe? According to insiders, unlike pork, beef and mutton, which are subject to strict inspection and quarantine, mink meat and raccoon meat are usually only used for fur, and their meat is usually not included in the range of meat food raw materials, and most of them are not inspected and quarantined.

　　Experts such as Ren Qiao from the College of Animal Science and Technology of Qingdao Agricultural University introduced that on February 25, 2012, minks in a mink farm in Hongdao, Qingdao developed symptoms and then died in large numbers. The investigation found that the farm was fed with a mixed feed made by itself, and raw fish, chicken head, eggs, pig liver and puffed corn flour were mixed evenly and diluted before feeding. The symptoms of sick mink are depression, loss of appetite or no food. Most minks are paralyzed in hind limbs, with acute onset and high mortality. Through pathological autopsy and laboratory test, the initial diagnosis was Clostridium botulinum poisoning in mink.

　　Ren Qiao introduced that mink Clostridium botulinum poisoning is an acute fatal poisoning caused by eating meat feed containing Clostridium botulinum toxin. Clostridium botulinum spores are widely distributed, and Clostridium botulinum is often contained in animal intestinal contents, feces, decaying corpses and decaying feed. The bacteria breed in animal carcasses, meat and feed to produce toxins. The main source of infection of Clostridium botulinum poisoning in mink is the feed contaminated by this bacterium.

　　Bao Linlin, an expert from the Institute of Experimental Animals of China Academy of Medical Sciences, introduced that human H5N1 subtype avian influenza virus A/Vietnam/1203/2004 was selected to carry out artificial infection test on ferrets. The results showed that human H5N1 avian influenza virus could infect ferrets, and the mortality rate of virus titer was 33%. The virus can be isolated from the heart, liver, spleen, kidney, small intestine and brain tissues of infected ferrets, which shows that the virus can infect ferrets’ lungs, brains, livers, kidneys and other organs and cause nervous system infection, which has the same characteristics as the H5N1 avian influenza virus strain that infects people.

　　In addition, some insiders told the First Financial Reporter that in order to increase the luster of mink, raccoon and other fur, farmers usually add some hormones during the breeding process, and people will do harm to their bodies after eating these animals.

　　After the COVID-19 outbreak, 19 academicians and scholars jointly called for putting an end to the illegal consumption and trading of wild animals and controlling the major public health crisis from the source. According to the appeal letter, there are loopholes in the domestication and breeding of wild animals, which are often called protection, domestication or breeding. In fact, it is illegal to buy, sell and eat wild animals, laying a hidden danger for the trade and consumption of wild animals.

　　According to the first financial reporter, recently, Fujian, Guangdong, Hainan, Yunnan and other places have closed down artificial wild animal farms and breeding grounds, and prohibited wild animals from spreading, transporting and selling.

　　"The trade and consumption of wild animals is mainly not a legislative issue, but more a problem of lax law enforcement." Shi Yucheng, a professor at Gansu University of Political Science and Law, said.

　　Ran Jingcheng, a member of the Standardization Technical Committee of National Parks and Nature Reserves, also said a few days ago that scientific research on wildlife breeding technology should be increased, and those species that can promote economic development, poverty alleviation and rural employment should be encouraged to carry out technical research and publish technical standards. Fixed-point processing of artificially bred wild animals and strict quarantine procedures.

　　Economic Daily-China Economic Net, Beijing, July 13 (Reporter Ma Changyan) In the first half of this year, the national real estate regulation and control policies have exceeded 300 times. How will the real estate regulation and control go in the second half of this year? Will the real estate regulation be relaxed in order to further stimulate economic recovery in the future? On July 9, China Renmin University China Macroeconomic Forum released a special report, pointing out that with the epidemic basically under control, all walks of life have resumed production and work in an all-round way, the real estate market is recovering rapidly, and the super-differentiation pattern has been further strengthened. Under the super-differentiated market structure, structural risks are more prominent, and the determination of regulation and control and the requirements for accuracy are further improved. In the future, China’s real estate market industry will show the characteristics of "super-differentiation of the market and firm regulation of policies" for a long time.

　　The market is recovering well.

　　Qin Hong, a senior researcher at the National Development and Strategy Institute of Renmin University of China, a major member of the China Macroeconomic Forum (CMF) and former director of the Policy Research Center of the Ministry of Housing and Urban-Rural Development, released a special report on CMF China’s macroeconomics on behalf of the forum. Qin Hong pointed out that China’s real estate market is recovering rapidly after the epidemic, and the performance of relevant indicators is relatively good.

　　The cumulative year-on-year decline in the transaction scale of new houses continued to narrow, and prices rose steadily. In terms of transaction volume, from January to April, the national real estate sales area decreased by 19% and the sales volume decreased by 13%, but the decline in sales area narrowed by 7 percentage points compared with that in January-March. The transaction scale of urban commercial housing continued to improve, and the transaction scale of some cities in May has achieved positive growth year-on-year. In terms of price, according to the 100-city price index of the Central Finger Research Institute, the price of new residential buildings in 100 cities increased by 0.31% in May, and increased by 0.74% from January to May, which was 0.34 percentage points lower than the same period of last year. The cumulative increase was still the lowest in the same period of the past five years, and the price showed the characteristics of steady and rising.

　　The land market is shrinking in volume and rising in price, and continues to heat up. From January to May, the supply and demand scale of residential land in 300 cities nationwide decreased year-on-year. Among them, the supply and demand of residential land in first-tier cities have increased significantly, and the transaction scale of second-tier and third-and fourth-tier cities has declined. The heat of the land market has obviously increased, and the average floor price and premium rate have reached a stage high. From January to May, the average floor price of homestead transactions increased by 20.9% year-on-year.

　　The growth rate of real estate development investment is better than that of fixed assets investment and infrastructure investment. According to the data released by the National Bureau of Statistics, the national fixed asset investment (excluding farmers) decreased by 10.3% from January to April, of which infrastructure investment decreased by 11.8%, manufacturing investment decreased by 18.8% and real estate development investment decreased by 3.3%. Overall, the resilience of the real estate investment side still exists.

　　Show a pattern of super differentiation

　　"After the epidemic, differentiation is not enough to describe the changes in the real estate market, and there has been a pattern of super differentiation in the real estate market." Qin Hong said.

　　The report shows that after more than 20 years of development after the reform of the urban housing system, the sales scale of the real estate market has increased from 100 million square meters in 1998 to 1.7 billion square meters in 2019, an increase of 16 times. At the same time of the total growth, the real estate market has been divided, and the market share of enterprises, financing costs, land reserve pattern, corporate profitability and real estate markets in different cities have all been divided. Under the epidemic, this differentiation is further intensified.

　　In terms of real estate enterprises, the intensification of differentiation appeared in 2015. From 2016 to 2019, the proportion of sales of the top 100 enterprises increased by 24.8% in four years, which is increasing at an average annual rate of 6%. Under the influence of the epidemic, the sales area and sales volume of the national real estate market were still negative in the first half of the year, but the threshold value of the top three real estate enterprises increased by 8.85 points, and that of the top ten real estate enterprises increased by 5.2 percentage points.

　　From the perspective of enterprise financing scale, the financing scale of overseas debt and credit debt of the top 30 real estate development enterprises accounted for 64% of the top 100 enterprises in the first half of this year; From the perspective of financing cost, taking the cost of credit bonds issued by real estate enterprises in April as an example, the financing cost of enterprises with the lowest cost and enterprises with the highest cost is five times worse; Judging from the land market, the number of land acquired by the top 30 real estate enterprises in the first half of this year accounted for 85% of the top 50 enterprises. The larger the enterprise scale, the lower the floor land price; The smaller the enterprise scale, the higher the floor land price. There is also a very obvious gap in the cost of land acquisition for enterprises.

　　There are also obvious differences in the performance of real estate market in different cities. From the perspective of cities, the land acquisition of the top 100 real estate enterprises in the first half of this year was mainly concentrated in five urban agglomerations, accounting for 60% of the land acquisition scale, of which one urban agglomeration in the Yangtze River Delta accounted for 30% of the land acquisition scale of the top 100 enterprises. Judging from housing prices, more than half of the top 20 cities in the first half of this year are concentrated in the Yangtze River Delta region. Not only between cities, but also within cities. In addition, there is super differentiation between residential real estate and commercial real estate, real estate demand in different lots and inventory of different housing enterprises.

　　Firmly control the policy direction.

　　In order to promote the stable and healthy development of the real estate market, since the beginning of this year, the central government has repeatedly set the tone for the real estate policy. In April, the the Political Bureau of the Communist Party of China (CPC) Central Committee meeting mentioned that "houses should be used for living, not for speculation, so as to promote the stable and healthy development of the real estate market". In May, the government work report emphasized that "the house should be used for living, not for speculation, so as to promote the stable and healthy development of the real estate market."

　　According to the statistics of the Central Plains Real Estate Research Center, the number of policies issued nationwide to stabilize the property market in the first half of this year was 304, up 21% year-on-year, setting a new historical record for the number of regulation in half a year. From January to April this year, the number of real estate regulation and control reached 238. With the stability of the real estate market, the number of real estate regulation and control decreased significantly, 35 times in May and 31 times in June.

　　The report pointed out that maintaining the stability of housing prices is crucial to China’s economic and social stability and financial security. In the medium and long term, China’s current housing prices are at a high level, and the fundamental contradiction in the real estate market has not been substantially resolved. The super differentiation of the real estate market makes it more difficult for real estate to regulate and deal with risks.

　　In this context, the report believes that the real estate market still needs to be firmly regulated in the future, and it is necessary to maintain "five invariants" in the direction of policy. First, the strategic positioning of "housing and not speculating" remains unchanged. The key to the policy is the word "speculation" to prevent the rebound of real estate speculation. Second, the supply system of "renting and selling at the same time" remains unchanged. The key to the policy is the word "rent" to develop the housing rental market. Third, the regulation mechanism of "policy by city" remains unchanged. The key to the policy is the word "city", and the city government takes overall responsibility for the stability of the local real estate market. The fourth is to achieve the goal of "three stabilities". The key to the policy is "stability" to prevent the market from ups and downs. Fifth, the real estate financial policy remained stable. The real estate market has always been highly sensitive to monetary policy, and the key to the policy is to stabilize the mortgage interest rate.

　　In view of the development status of China’s real estate market, Qin Hong put forward five suggestions on behalf of the forum research group: First, we should still take the goal of stabilizing housing prices, take measures according to the city, and grasp the pace of real estate development. The second is to coordinate the development and regulation of real estate with the metropolitan area as the scope. The third is to guide the transformation and upgrading of the real estate industry with urban renewal as the starting point. The fourth is to control risks as the bottom line and reserve policies and measures for various camera decisions. Fifth, systematic market monitoring is carried out with indicators such as quantity, price and finance as the core.

From scientist to entrepreneur, Yu Kai is not the first person to "run away" in the field of artificial intelligence.

Despite the previous achievements in scientific research, joining in entrepreneurship means facing the reality of bone feeling.

In March 2015, Yu Kai said in an interview: "If a business can get the resources it deserves to do what it wants, then choose to start a business; If you join a big platform and have more resources to do one thing, then join a big platform. " Sure enough, three months after that, he left Baidu and founded Horizon.

Yu Kai

From the initial "no one pays the bill" to October this year, Horizon successfully won the investment of 2.4 billion euros from Volkswagen, setting the largest single investment record for Volkswagen in the past 40 years, and establishing a joint venture company with audi ag’s software company. The transformation of Yu Kai’s identity can be described as unsuccessful.

Before becoming the founder of Horizon, Yu Kai’s label was the top international scholar in the field of machine learning and the main promoter of deep learning technology in China. His published papers were cited more than 20,000 times, and he won the silver award for the best paper in ICML-2013 International Machine Learning Conference. He himself also served as the domain chairman of ICML and NIPS, two major conferences of machine learning.

Yu Kai’s achievements in the academic field go far beyond this.

NEC Research Institute of the United States was once one of the major centers of international machine learning research. During his tenure, Yu Kai established a highly prestigious technology research and development team in Silicon Valley. This team is one of the earliest and most active teams in the field of deep learning in the world. A series of technologies led and developed by him have pushed image object recognition to a new level worldwide, and won many international famous awards.

After joining Baidu in 2012, the voice technology team, deep learning technology team and image technology team led by Yu Kai won the "Baidu’s highest award" three times in succession, creating records of various technical and business teams within Baidu.

In the eyes of outsiders, Yu Kai at that time, both academically and professionally, was smooth sailing.

But at this time, he chose to start a business.

Yu Kai’s reason is straightforward: "In the past three years, what I have done at Baidu is to promote artificial intelligence in the cloud. But I think there will be a bigger trend in the next few years that I have to do: from artificial intelligence in the cloud to artificial intelligence around everyone. "

Therefore, Yu Kai, who has always believed in "doing things is the most important thing", founded Beijing Horizon Information Technology Co., Ltd. in July 2015, focusing on edge computing in the field of artificial intelligence.

From the moment the company was founded, in his own words: First of all, I will forget that I am a scientist more and more.

To be a scientist, you can put the mainexperienceDo research and write papers, but as an entrepreneur, you should focus more on business and customer needs.

Yu Kai has always wanted to grasp some "truth" things in this process, for example, things that can really create long-term value. With this idea in mind, at the beginning of Horizon’s establishment, he played the slogan of "making brains for machines", and avoided the edge of the field giants, took the edge computing route, and insisted on making AI chips.

It was really hard at first.

When recalling the initial stage of starting a business and determining the development direction, Yu Kai mentioned: At that time, we were predicting a far future, a future that might take 20 years as its dimension. From computers to smart phones, and beyond, what is a bigger computing platform than these? At that time, they were sure,beRobot computing platform. AI chip is the indispensable key to realize this calculation.

Now that we hear about AI chips, it’s needless to say its importance. But when Horizon was founded, not every investor could understand the "blueprint" in Yu Kai’s eyes. As a direct result, the horizon was once unsustainable. Until smart cars become "robots"calculate"The first and biggest landing scene at present, everyone began to understand that Yu Kai had bet on it.

In 2020, smart cars ushered in an outbreak period. As a result, there is a global "lack of core" in the automotive industry.question.

A chip with excellent computing power, like a smart brain, can accurately control the behavior of the vehicle. A series of functions, such as environmental awareness, route planning, driving assistance and so on, advertised by smart cars all need to rely on chips to be realized.

This is also consistent with what Yu Kai has always wanted to do. He has always believed that the real significance of artificial intelligence is not to survive and develop as the opposite of human life, but to support people’s decision-making and enhance their ability. Once the smart car scene is broken down, this ability will definitely spill over to others.floatApplication scenario of robot.

In August 2019, Horizon announced the mass production of China’s first car-class AI chip "Journey 2";

In September 2020, Horizon officially launched the AI chip "Journey 3";

In July, 2021, Horizon released "Journey 5", a high-performance and large-computing, full-scene intelligent central computing chip for the whole vehicle.

……

Yu Kai once said, "The course of a scientist’s entrepreneurship is not based on business opportunities,FromStart in the future. "

This cooperation between Horizon and Volkswagen may be the next future in Yu Kai’s plan.

"Nine -ball Queen" Pan Xiaoting, the value of more than 1 billion is conservative. Today, the age of 39 is still single and is still a big daughter of Huanghua.

She once announced her own spouse selection criteria:

1. The face value is high, and the height cannot be lower than 1 meter 76;
2. Mature and stable, you must have your own career;
3. To pursue her actively, if you don’t take the initiative, you would like to miss it;
4. Don’t have filial piety.

Netizens shouted directly: It’s too difficult to take off the order!

There is a saying in the billiard industry called "Men have Ding Junhui, and women have Pan Xiaoting."

Pan Xiaoting is the first player to win the World Championship in my country’s billiard industry. He is the holder of the 9 -ball World Championship, which is therefore called the "Nine Ball Hou".

Pan Xiaoting was born in Jining, Shandong in 1982. His father was a billiard enthusiast and opened a bill for a bill. Due to the excellent ball skills, it is called "Pan Yi".

In Pan Xiaoting’s childhood, he did not show any interest in billiards, but was interested in painting.

She drew perseverance, and one painting has been for several years. Art has also become her dream.

Until college, Pan Xiaoting rarely played billiards. Occasionally, Pan Xiaoting was in a bad mood because of conflicts with his classmates.

As soon as home, she picked up the club of the table to vent her emotions.

What she and her father did not expect was that although Pan Xiaoting had not practiced, she scored several balls at hand.

This is obviously a talented player.

However, at the time, Pan Xiaoting didn’t think too much, and his father only hoped that his daughter could grow up happily and did not deliberately train billiards, but occasionally played.

During the college entrance examination, Pan Xiaoting, who has always liked painting, applied for art colleges. Unexpectedly, it was fell on the list.

For a while, Pan Xiaoting lost his direction in the future and doubted himself.

Fortunately, after repeated consideration, Pan Xiaoting decided to learn billiards with his father.

For her daughter’s future, her father began to train her strictly.

Regardless of the winter or cool summer, Pan Xiaoting play billiards for more than seven hours a day. For a month, it can only take a break, sometimes only half a day.

What makes Pan Xiaoting feel more hard is that in the summer, even the hottest weather, the fans are not opened during training. Pan Xiaoting often sweats hotly and has to continue training.

In winter, even if your fingers are frostbite, you still have to practice.

For her, occasionally wanting to be lazy, she is not allowed.

A boy is even difficult to endure this training intensity, and it is a flower girl.

During that time, Pan Xiaoting thought more than once that her father didn’t love her, so she had a hard time to eat her so much.

Fortunately, Huang Tian lived up to the painstaking people, and Pan Xiaoting’s dedication got the return.

In 1998, Pan Xiaoting’s father, Pan Jian, took Pan Xiaoting to Beijing to participate in the first nine -ball women’s opening game.

In Beijing for a month, in order to save money, the father and daughter lived in a 15 -dollar air -raid hole, eating 10 yuan of fish flavor shredded, and life was very difficult.

Fortunately, the two were not very bad. Pan Xiaoting won the championship in one fell swoop and won 4,000 bonuses.

My father was proud of his daughter, and asked what his daughter wanted to eat?

Pan Xiaoting said excitedly:

"Dad, I want to eat Beijing roast duck!"

Pan Jian Shuang agreed quickly and immediately took her to Quan Jide.

As a result, the father and daughter opened the menu and looked at them immediately!

A roast duck, it costs 156 yuan!

Although the fragrance of roast ducks made Pan Xiaoting sorrowful, she still felt very distressed and pulled her father’s corner and said: "

"Dad, let’s forget, let’s take a look elsewhere."

Pan Jian said to his daughter:

"Girl, eat it when you come, let’s order half!"

So Pan Xiaoting ate it quickly. At that moment, Pan Xiaoting felt her father loved her again.

In order to make parents live a better life, Pan Xiaoting worked harder to train. And on the road of billiards, she also opened all the way.

In 2000, Pan Xiaoting won the championship again in the national sports competition. In the same year, she won 6 national championships.

Since then, Pan Xiaoting has opened a journey to win.

In 2007, Pan Xiaoting won the world championship in the World Championship final and became China’s first billiards world champion.

In addition to getting bonuses, Pan Xiaoting also made a lot of advertisements and received a lot of endorsements. It is estimated that the value is conservative!

There is no doubt that Pan Xiaoting is already the pride of his parents in his career. However, on personal problems, Pan Xiaoting made his parents very concerned.

At the age of 39, she is still single and is still a yellow flower girl.

During the period, although he had a scandal with Ding Junhui, Pan Xiaoting showed that he was just a good friend!

Today, Ding Junhui’s children will make soy sauce, and Pan Xiaoting is still alone.

For the other half, Pan Xiaoting also announced her request:

It seems that it is not high, but it is not found. It is also impressive. Is it really not good for a boyfriend?

In addition to the "Nine Balls" Pan Xiaoting, there is also a particularly excellent woman, which is nearly 40 years old, worth 10 billion yuan, and is still single.

She is a woman who refuses Ma Yun three times, currently the director of Yunfeng Fund, Li Ying.

Li Ying graduated from the Massachusetts Institute of Technology. Because of his high IQ, he was too good, and was appreciated by Ma Yun.

However, Ma Yun invited the other party to join his company three times, but he was rejected.

Until the fourth time, Li Ying promised to serve as a director of Yunfeng Fund.

Today, this strong woman is nearly 40 years old, with tens of billions of dollars, but still single.

In this regard, some netizens said:

Such a woman is not good at climbing, and it is a kind of sadness to be stronger than no one.

Some netizens said:

If you have money, why do you have to get married? Single is cool for a while, and he has been single.

How do you think about this? Welcome to leave a message. The picture comes from the Internet, invading and deleting.

Shanghai, September 27th (Gong Li SHA) On September 27, the Shanghai Municipal Party Committee and the Municipal Government held a press conference. An introduction of effectiveness, deputy director of the Cultural and Tourism Cheng Meihong City Bureau, Deputy Director of Liu Min City Commercial Committee, Minister Lu Xiaohui, Propaganda Department of Xuhui District Committee, Changlong Wanlong, Jing’an District, deputy district, and deputy head of the Chujie Yan District of Songjiang District attended the meeting.

Create a "new space" everywhere for the tourist scene

Shanghai is a well -known tourist city. This is an excellent tourist city "king is everywhere and should be accessed from time to time." The journey of this Tourism Festival has adhered to Jiangsu, the city of festivals, excavating tourism landmarks, new carriers, and new methods to fully stimulate the vitality and release of the city, in order to better serve the development of the Yangtze River Delta.

First, the tourist destination that focuses on promoting shows the Yangtze River Delta. In the context of promoting the development of high -quality cultural tourism integration in the Yangtze River Delta, strive to take the lead in traveling in the "same city effect" in tourism. In some cities in the Yangtze River Delta, the original "good neighbors" to the current "family." This year’s tourist festival, our first time, our first tourism festival. Four items of implementation. The first group of the Yangtze River Delta Tourism Festival was at the Nantong venue, Wenzhou, Huangshan, and three cities launched nearly 100 theme activities. It attracted the participation and attention of more than 8 million people.
