On March 18th, the Third Yangtze River Bridge in Wuhu staged a scientific and technological wonder: 200 Chery cars with intelligent driving crossed the bridge at a uniform speed of 40km/h, and the intelligent driving feat of zero human intervention in the whole process opened the prelude to the intelligent strategy conference of "oil, electricity and intelligence in the world". Known by the industry as the "Smart Night", this grand event not only launched the 500/700/900 smart driving, but also crushed the technical strength of the industry with the iterative speed of the algorithm, announcing that Chery officially became the first echelon of smart driving in the world.

[Intergenerational Revolution of Algorithms]

Chery’s intelligent layout presents a clear step-by-step evolution: the end-to-end large model (E2E) mass-produced in 2025 took the lead in breaking the shackles of traditional modularity, and through the direct optimization of perception-decision, the efficiency of the Falcon 500/700 series in anthropomorphic decision-making was significantly improved. What is more worth looking forward to is that Eagle 900 deeply integrates VLA (Visual Action Language Model) with WM, and has dual capabilities of "scene generation+strategy deduction", which can predict complex traffic situations in advance.

"Practice of technical equality"

When the industry focused on the electrified track, Chery opened up a new battlefield with the wisdom of oil and electricity. Falcon Intelligent Driving System innovatively develops a digital twin platform, which overcomes the problem of response delay of traditional fuel vehicle drive-by-wire actuators and shortens the adaptation period of intelligent driving system. This makes such fuel vehicles also have high-speed NOA capability, realizing real technical equality. In the field of Off-Road intelligence, Falcon Intelligent Driving Off-road, the world’s first off-road intelligent driving technology, broke through the perception bottleneck of unpaved roads, and integrated satellite remote sensing data through Xinghai big data platform, which significantly improved the pass rate compared with the traditional off-road auxiliary system.

[Global data closed loop]

Supporting the technological transition is the global data engine built by Chery. The model learning mileage of 20 million kilometers per day forms a complete closed loop of "global acquisition-cloud training-scene simulation". Especially in overseas markets, 4.5 billion kilometers of real intelligent driving data feedback algorithm optimization has successfully solved regional problems such as the passing rate of complex roundabout in Europe and the perceived stability of dusty weather in the Middle East. Relying on China’s first EU dual certification qualification, Chery plans to land in Europe with Falcon 700 in 2026, and knock on the door of the high-end intelligent driving market with the verification data of 1 billion kilometers in the "digital parallel universe".

[Ecological competition pattern]

Facing the high-precision map dependence of NCA of Huawei ADS 2.0 and XNGP of Tucki, Chery chose to make a differentiated breakthrough: the update frequency of weekly algorithm iteration is four times faster than the industry average; Full-power type adaptability, covering the pain points of traditional car enterprise transformation; Breakthrough of off-road scenes, filling the blank market of intelligent driving. This technical layout has been verified on ET in Xingyue-a heterogeneous redundant system with 30 sensors, and the decision-making is highly anthropomorphic in the unprotected left turn scene.

From the intelligent driving along the Yangtze River to the verification of 1 billion kilometers in the digital universe, Chery is reshaping the industrial structure with intergenerational innovation of algorithms. When Falcon 900′ s VLA+WM architecture realizes L3-level automatic driving, this technological leap from end to end will lead China’s intelligent driving to a new era dominated by "world model".

You don’t need to be a fitness expert

There are not many technical thresholds.

You can "I" walk alone.

After "City Walk" became

After the "new favorite" of people’s travel and rest

"City Ride" is also hot and "out of the circle"

A pair of iron legs and two sleeves.

Ride your beloved bike and roam the city.

It has become a leisure way for many people to punch in.

The literal translation of "City Ride" is city riding. The so-called riding, riding tools are bicycles. China’s cycling culture has experienced ups and downs. In 1956, a 28-inch "permanent" model was rolled off the assembly line, and New China had the ability to independently design and produce bicycles. From "Phoenix" to "Flying Pigeon", the bicycle was not only one of the "three big things" for generations of Chinese people to get married, but also connected with the mobile China in the eyes of their parents. Later, with the rise of vehicles such as family cars and battery cars, the status of bicycles as "commuting kings" was gradually replaced.

What is the charm that makes bicycles a new favorite again? Let’s talk about it today.

Why is Citylide fascinating?

The popularity of Citylide is beyond many people’s imagination. According to statistics, at present, there are more than 100 million people cycling regularly in China, and nearly 10 million people participate in cycling. Except for a few professional cyclists, most people still take the City Ride route, which is a hobby of cycling. Walk too slowly, drive too fast, and ride just right.

Notes on cycling on social platforms.

So, why do so many people have a special liking for the new "online celebrity Movement" of City Ride?

The sense of surprise of "meeting unexpectedly"

For office workers who work from nine to five in the city, the usual life path is fixed between home and work, and the scenery on the way to and from work every day is similar. Different from the simple commuting at two o’clock and one line, Citylide’s route is more random and diverse, and it can also bring more fresh experiences.

Riding and stopping on a "popular" path, maybe something new will pop up at the next intersection: an ice-cold special latte, a pot of steaming cakes and snacks … A moment of free energy can cure the fatigue of the day.

Ultimate pure "cost performance"

Compared with style and style, nowadays, people pay more attention to the cost-effective life, and consumption has also changed to practicality, applicability and economy, and City Ride meets everyone’s needs. As a zero-emission travel mode, City Ride can not only reduce the carbon emissions in the transportation field to a certain extent, but also contribute to environmental protection. It also finds a "three-all" solution that can not only exercise, but also change the sports scene for urban people who are inconvenient to exercise due to conditions such as venues and equipment.

In addition, riding can also choose not to match the speed, not to roll the equipment, and how much investment is controlled by yourself. Although the word City Ride seems to carry the label of exquisite petty bourgeoisie, in fact, the cost is not high and the operation is simple. What everyone pursues is the happiness of "doing more with less money".

"God Assist" of Social Platform

A large number of "planting grass" posts and sharing posts on social platforms have sent a wave of "god assists" to the popularity of Citylide, attracting the attention of a large number of sports enthusiasts.

Every weekend or weekday night, about three or five friends unlock different cycling routes and various new ways of playing, and explore new fun of urban life during cycling, which has become a lifestyle sought after by more and more people.

How can City Ride be more comfortable?

What are the precautions?

When we ride a bicycle, there are three parts of our body that are in direct contact with the bicycle, that is, our hands (handlebars), our feet (pedals) and our buttocks (seat bags). The relationship between the contact points between the body and the bicycle and our height directly determines the posture, muscle force efficiency and comfort when riding.

How should we adjust these points according to our height?

We usually ride a bike, and we often adjust the distance between these points by adjusting the height of the seat bag to adjust the force angle of the thighs and knees when pedaling. If the height of the seat bag is too high or too low, the leg muscles will not be at the proper angle of force when riding, resulting in insufficient muscle strength, which will reduce the riding efficiency and make us feel uncomfortable.

Some studies have found that for cyclists, there is still a 30-degree bend (that is, a slight bend of the knee) in the knee bending angle (as shown in the figure) when the pedal is stepped to the end, and riding with a body leaning forward angle of 55 is the most comfortable.

Source: Priego Quesadaji, Pé rez-Soriano P, Lucas-Cuevas AG, Salvador Palmer R, Cibriá n Ortiz de Andarm. Effect of Bike-Fit in the Perception of Comfort, Fatigue and Pain. J Sports Sci. 2017 Jul; 35(14):1459-1465. doi: 10.1080/02640414.2016.1215496. Epub 2016 Aug 4. PMID: 27490817.

Next, I will teach you a simple way to adjust the height of the seat bag. The specific method is to hold the seat bag under your arm and straighten your arm. If your fingertips are just at the center of the car, then the height of the seat bag is more appropriate.

Although this adjustment is not accurate enough, it is no problem for you to ride comfortably for several kilometers. Of course, if your driving skills are poor and the road conditions are complicated, you can lower the height of the seat bag a little to make an emergency stop.

Of course, the original intention of riding is no matter how good and the experience is wonderful. If there is no safety as the premise, nothing can be discussed. These safety knowledge should be kept in mind:

Cycling in the right place

When riding, you should choose a square or park with riding lanes; When riding a bike on the street, be sure to take the bike lane, and it is strictly forbidden to walk through the traffic; Avoid cycling in crowds. Pedestrians who are knocked down by bicycles, especially those who hurt their heads, are likely to face fatal risks.

Riding age should be legal.

Article 72 of the Regulations for the Implementation of the Road Traffic Safety Law of the People’s Republic of China stipulates that driving bicycles, tricycles, electric bicycles and motorized wheelchairs for the disabled on the road shall comply with the following provisions: driving bicycles and tricycles must be at least 12 years old; Driving electric bicycles and motorized wheelchairs for the disabled must be at least 16 years old.

Obey the rules and order

When riding a non-motor vehicle on the road, it is necessary to pass in the non-motor vehicle lane; If there is no non-motor vehicle lane on the road, you should drive along the right side of the road. During riding, you should obey the traffic signals, stop at the red light, go at the green light, don’t race against the second, don’t be distracted, ensure safety before passing, and don’t rush through the red light for a moment!

Stay away from vehicle blind spots.

When a large vehicle turns, the trajectories of the front and rear wheels do not coincide, which will present a meniscus-shaped blind zone. If you are in this area at this time, it is easy to be blown down and involved in the bottom of the car, resulting in a crushing accident.

If you want to enjoy riding, it is not only related to urban planning and traffic management, but also depends on the joint efforts of every cyclist.

Since the opening of the bicycle lane connecting Huilongguan and Shangdi, 5.24 million people have cycled, contributing more than 1,500 tons of carbon emission reduction. Last year, the Second Ring Road completed the optimization and transformation of the slow-moving system. The width of the non-motorized vehicle lane was more than 3 meters, and the traffic efficiency increased by 25% … These data are only a microcosm of the improvement of the slow-moving system in Beijing. More detailed changes have made the citizens feel more secure when riding and walking, and it has become a social consensus to respect slow-moving gradually.

　

According to the survey data, in 2021, the proportion of slow traffic trips in the central city of Beijing reached a new high in the past 10 years, reaching 47.8%, an increase of 6.9% over 2017, and the citizens’ willingness to travel slowly continued to increase. By the end of 2021, 84.1% of the citizens thought that the slow-moving rectification was effective.

　

According to the plan, this year, Beijing will continue to promote the transformation and upgrading of the slow-moving system, promote the construction of the east extension project and the south exhibition project of bicycle lanes, optimize the slow-moving corridors of the East Third Ring Road and the North Fourth Ring Road, and improve the walking and cycling environment.

"Small actions" achieve "big effects" in improving the slow-moving environment

　

The south exit of Meishi Street is the node connecting Meishi Street and Liangguang Street. There is not only a business district nearby, but also a number of residential communities. There are many cars and people every day. Since August last year, a bicycle-patterned left turn signal light has been added to the signal pole at this intersection. Cyclists who turn from west to north can turn left only by waiting for the green light once, and the passing time is only 15 seconds.

　

Before this, cyclists need to get off at the crosswalk and wait for the signal light twice to completely pass the intersection, which takes at least 3 minutes. In order to speed up, many cyclists will risk cycling through crosswalks, even diagonally crossing and retrograde.

　

At the intersection of Wangfujing Street and Dashamao Hutong, after a series of transformations, the turning radius of vehicles increases, and motor vehicles need to slow down. Both roads have 2.5-meter-wide non-motor vehicle lanes, and bicycles pass smoothly.

　

This change is due to the continuous upgrading of the slow-moving system promoted by Beijing.

　

At the end of 2019, Beijing put forward the transportation development concept of "slow travel priority, public transport priority and green priority", which fully reflected the transformation from "car-oriented" to "people-oriented" in terms of planning, construction, management and law enforcement, and some changes in details made citizens feel more at ease when riding and walking.

　

"It can be said that it has achieved great results with small moves. Since 2021, a total of 74 bicycle intersections have been set up in Beijing, and the traffic flow lines and access rights of motor vehicles, non-motor vehicles and pedestrians have been clarified, and the traffic order at intersections has been significantly improved." Jing Lubo, the first-level director of the Urban Road Management Office of the Beijing Municipal Transportation Commission, said that the transformation of the intersection of Wangjing West Road and Futong West Street is very representative. The original intersection was too large, which led to serious interweaving of people and vehicles. After the transformation, it was reduced from 8,000 square meters to 3,000 square meters, the intersection area was reduced by about 60%, the pedestrian crossing distance was shortened by about 25%, the traffic capacity of motor vehicles at the intersection was improved by about 10.6%, and the queue length of motor vehicles was reduced by about 26.1%. "In Beijing, such big intersections are gradually slimming down." Jing Lubo said.

　

Shijingshan Insurance Industrial Zone is also a typical achievement of Beijing’s slow-moving system transformation. Through the "four-way integration" of waterfront greenway, garden trail, park service road and air corridor, a slow-moving system demonstration zone has been built, attracting many citizens to choose cycling and walking.

More abundant and smooth road choices also make the order in the waterfront greenway better and better. Peng Peng, head of the Road Facilities Section of Shijingshan District Urban Management Committee, said that when the greenway was first opened, there would be electric vehicles driving in, which was a safety hazard. "At that time, we also planned to send more people on duty to discourage them. However, after the slow-moving system of other roads near the river was upgraded, electric cyclists found that it was more spacious and smoother to bypass other roads. Naturally, they did not walk through the greenway. By increasing supply, they also achieved the effect of standardizing order."

　

Carry out the physical examination of slow traffic, and make improvement according to the problems.

　

"What is the current situation of the traffic environment of the slow-moving system? Has the transformation achieved practical results? In what areas can we make efforts in the next step? "

　

These problems are all concerned by Wang Shuling and his colleagues. Wang Shuling is the head of the slow traffic team of Beijing Traffic Development Research Institute and the director of the track institute. Her research in the field of slow traffic and monitoring the results of Beijing slow traffic management will provide reference for relevant departments to formulate policies and determine future action plans. "Slow-moving transformation is not a blank sheet of paper, there will be many difficulties and obstacles, and it is a long-term work."

　

She believes that bicycles are not only a means of travel, but also an important way to alleviate congestion, improve residents’ health, promote street vitality and help reduce carbon emissions. "In the future, the slow traffic environment in Beijing will be more friendly, and the slow traffic will also be deeply integrated with the charm of the city and the health of residents."

　

Starting from 2020, based on the development level of Beijing’s slow traffic and drawing lessons from the advanced experience of international cities such as Copenhagen and London, the transportation department will build a travel effect-oriented evaluation and assessment system for slow traffic services.

　

"In fact, it is to carry out physical examination for our slow traffic system. Only by objectively reflecting the status quo and finding problems can we formulate more targeted upgrading and transformation plans." Wang Shuling said that 2020 is the initial year of Beijing’s slow traffic physical examination. Around the use effect, more than a dozen indicators were set in three dimensions: facilities, management and usage. In 2021, fine-tuning, road tree-lined and other indicators were added, which also reflected the focus on the actual needs and demands of citizens.

　

Through the physical examination of slow traffic, the spatial data information of slow traffic in six districts, Tongzhou District and Economic and Technological Development Zone was formed for the first time. On this basis, the Work Plan for Improving the Quality of Slow Traffic System was studied and formulated for three consecutive years. With the joint efforts of various departments and local governments, 43 projects were formulated and promoted according to the target in 2020 and 2021, and the construction of slow traffic system formed a benign closed loop.

　

The "physical examination results" in 2021 showed that the non-motor vehicle width compliance rate in the core area, Shijingshan District and urban sub-centers all exceeded 80%, with the core area having the highest compliance rate of 83%. At the same time, in recent years, with the continuous improvement of facilities governance and order management, the illegal phenomenon of facilities occupying trails and motor vehicles invading bicycle lanes has been continuously improved. In 2021, the rate of facilities occupying trails decreased by 10.5% compared with that in 2020, and the rate of illegal intrusion of bicycle lanes decreased by 47% compared with that in 2020. A safe and friendly bicycle travel environment has gradually taken shape.

　

Bicycle lanes have contributed 1,500 tons of carbon emission reduction.

　

In Beijing, cycling and walking have become more comfortable, and it has increasingly become a social consensus that cars make way for bicycles and respect slow travel. According to the survey data of the third party, among the international cities with similar population size, the mileage of slow traffic facilities in Beijing ranks in the forefront, and the mileage of bicycle lanes ranks first in the total scale.

　

Among all modes of transportation, cycling can be regarded as a "zero-carbon" travel choice. According to the research data of Beijing Traffic Development Research Institute, bicycle travel can reduce carbon dioxide emissions by 0.17 kg per person per kilometer compared with car travel. The change of travel structure is very important for "carbon neutrality". If a car user switches to cycling, it can reduce one ton of carbon emissions a year, and basically achieve the goal of "carbon neutrality" from an individual perspective.

In 2019, Beijing built the first bicycle lane with a total length of 6.5 kilometers, connecting Huilongguan and Shangdi Software Park. Compared with private cars and buses, it saved travel time by 32% and 50% respectively, which solved the travel problems of a large number of commuters.

　

"Now, cycling is not only a mode of transportation, but also a way of life." Wang Shuling introduced that the operation of bicycle lanes not only provided convenient transportation options, but also cultivated a large number of "iron powder" for bicycle commuting. Up to now, the cumulative usage of bicycle lanes has exceeded 5.24 million person-times, and the average daily riding volume is 4,500-5,000 vehicles/time. According to the calculation of traffic mode transfer of users of bicycle lanes, bicycle lanes have contributed more than 1500 tons of carbon emission reduction.

　

Nowadays, Beijing is promoting the construction of slow traffic demonstration roads to drive more citizens to choose cycling as a green mode of transportation.

　

After the bicycle lane is completed and opened to traffic, the west extension project will continue to be implemented in 2020, and the left turn sign of non-motor vehicles and special signal timing will be added at the intersection for the first time. In 2022, the east extension and south exhibition projects of bicycle lane will be started, and the radiation-driven function of bicycle lane will be completely activated to build a brand-new green commuter corridor.

　

Last year, the optimization and reconstruction project of the second ring auxiliary road slow-moving system was also a "star project". After the reconstruction, the width of non-motor vehicle lanes reached more than 3 meters, the traffic efficiency increased by 25%, and the morning and evening peak riding flow and traffic speed increased by 8% and 5% respectively. The quality improvement projects of slow-moving systems such as the extension line of Dongdan North and South Street and Ping ‘an Street have also been completed one after another, and the whole road has achieved slow-moving priority, smooth riding and proper walking.

Bike-sharing’s annual cycling volume reaches 950 million.

　

Bicycles are "returning" to Beijing, and the service and management measures need to be constantly improved and strengthened.

　

In 2021, the proportion of slow traffic trips in central Beijing reached a new high in the past 10 years, reaching 47.8%, an increase of 6.9% over 2017, and the citizens’ willingness to travel slowly continued to increase. On 51 roads, such as Xinjiekou Outer Street and Tiantan East Road, the number of morning peak rides exceeds 3,000 per hour.

　

The total number of bike-sharing in Beijing is about 950,000, and the daily average number of riders exceeds 2.4 million, making it the best choice for connecting urban rail transit.

　

Since entering Beijing in 2016, bike-sharing has played an active role in connecting the "last mile" of public transport and advocating citizens’ green travel. At present, the number of operating enterprises in bike-sharing has been reduced from 16 in its heyday to 3 in Meituan, Hello and Qingcheng, and the number of operating vehicles has been adjusted from 2.35 million to about 950,000. The compliance rate and dynamic access rate of operating vehicles are above 95%, initially forming a "1+N" pattern with one operating area in the central city and n operating areas in the suburbs, and the vehicle operating area has gradually expanded from the Fifth Ring Road to all administrative districts. In 2021, the annual cycling volume of bike-sharing in the city reached 950 million, and the highest cycling volume in a single day exceeded 4.71 million.

　

In order to continuously standardize the development of the Internet bicycle industry, the Municipal Transportation Commission has established a comprehensive supervision system to promote the healthy development of the industry. In order to standardize the parking of these bike-sharing and promote the integration of the slow-moving system and rail transit, Beijing has completed the construction of 224 bike-sharing electronic fences in 51 key rail transit stations, realizing the settlement of the entry. Up to now, more than 26,000 parking areas have been designated in bike-sharing, and 16 no-parking areas have been publicized in the core area, and the coordinates of all parking areas, no-parking areas and parking management areas have been pushed to enterprise clients to guide citizens to park in an orderly manner. At the same time, through the joint convention jointly launched by operating enterprises and industry associations, the riders who repeatedly violate the rules will be jointly punished, riding will be restricted, and citizens will be guided to regulate their car use behavior.

Compress the space of motor vehicles and return the road to walking and cycling.

　

A survey on the slow-moving system shows that more than 54% of Beijing residents believe that motor vehicle interference is the most important factor affecting riding comfort, among which "illegal parking" and "unreasonable parking space setting" are more intuitive; There is also a survey by relevant departments that nearly 70% of cyclists believe that order is an important factor affecting cycling.

　

Yang Xinmiao, deputy director of Tsinghua University Transportation Research Institute, has been engaged in research work in the fields of green transportation and traffic safety for a long time, and he often chooses green travel modes such as cycling.

　

He believes that it is the key to ensure the smooth and orderly slow-moving system to go its own way. "The sidewalk is for people to walk, and the bicycle lane is for people to ride." In this regard, he put forward a number of specific suggestions: no parking within three parking spaces at intersections, no parking within two parking spaces at bus stops, no parking within two parking spaces at the entrance and exit of residential areas, and shopping malls, schools, hospitals, etc. should help smooth the walking and cycling in front of the door, and motor vehicles should be allowed at night.

　

In order to further protect the right of way, Beijing is gradually rectifying the parking spaces with problems, and continuously strengthening the order management of the slow-moving system and increasing the investigation and punishment of roadside violations of motor vehicles. In the future, new electronic toll parking spaces on roads will also be reviewed in advance, and can only be set if the width of non-motor vehicle lanes is met.

　

Jing Lubo introduced that Beijing has compiled a series of planning documents such as "Beijing Slow Travel System Planning (2020-2035)" to clarify the future development orientation of the slow travel system, and formulated a series of standards and technical rules such as "Technical Guide for Improving Pedestrian and Bicycle Traffic Facilities in Beijing", highlighting the principle of street space allocation with priority on walking and bicycles. It is the first time to reduce the width of motor vehicle lanes to widen bicycle lanes and trails, pay attention to the priority of slow travel at intersections, and set up bicycles.

　

This year, the slow corridor of the East Third Ring Road and the North Fourth Ring Road will be optimized.

　

The work of promoting the construction of slow-moving system continues. In May this year, Beijing successively issued the Traffic Development and Construction Plan of Beijing during the Tenth Five-Year Plan and the Action Plan for Comprehensive Traffic Management of Beijing in 2022, which set clear requirements for improving the slow traffic environment in the future.

　

Jing Lubo told reporters that this year, Beijing will continue to make efforts to improve the slow-moving system. At present, relevant plans are being formulated and improved. "Typical projects include the slow-moving corridor construction projects of the East Third Ring Road and the North Fourth Ring Road, and will continue to optimize bicycle lanes and trails along the route to make green travel smoother and safer."

　

According to the Action Plan for Comprehensive Traffic Management in Beijing in 2022, in 2022, Beijing will continue to optimize and upgrade the green travel environment, and accelerate the construction of Dongtuo (Liangzhuang West Street-Lincui Road) and Nanzhan projects of Huilongguan Bicycle Dedicated Road; Optimize the slow corridor of the East Third Ring Road and the North Fourth Ring Road (Haidian Bridge-Zhixinqiao) to improve the walking and cycling environment; With the goal of building city slow traffic system, which mainly serves commuting, we will speed up the compilation of slow traffic planning and build a slow priority demonstration block, with at least one in the central city, Tongzhou District and Economic Development Zone. At the same time, it will also promote the connection and integration of garden greenways, waterfront roads and urban road slow-moving systems. Build 20 slow-moving boulevards to increase the comfort of walking and riding. Create 21 cycling routes of "Walking in Beijing" to promote the deep integration of slow travel and tourism.

　

If we turn our attention to the long-term goal, Beijing’s expectation for slow traffic is not limited to the traffic field, not only to "build a pedestrian and bicycle-friendly city and form a continuous and safe slow traffic network", but also slow traffic will become a part of citizens’ healthy life.

　

"Beijing Traffic Development and Construction Plan during the Tenth Five-Year Plan" depicts such a picture for the future development of the slow-moving system: in the "last mile" connection of public transportation, walking and cycling will play a greater role; The slow-moving system in the Fifth Ring Road is continuously networked, all eligible roads are divided into non-motor vehicle lanes, and bicycle priority signs are added to all non-motor vehicle mixed roads; Pedestrians will also be safer when crossing the street. Pedestrians will have exclusive safety facilities when crossing the street, and bicycles will no longer need to detour and retrograde when passing. Streets and blocks will also be more suitable for walking slowly. When riding on the road, citizens will enjoy more trees and trees, and the riding environment will be more comfortable and pleasant.

　　When listening to the work report of the Shaanxi Provincial Party Committee and the provincial government recently, General Secretary of the Supreme Leader pointed out that the most arduous and arduous task of building a socialist modern country in an all-round way and solidly promoting common prosperity is still in the countryside, and the gap between urban and rural areas must be gradually narrowed. The General Secretary of the Supreme Leader also stressed that it is necessary to improve the system and mechanism of urban-rural integration development, improve the policy system of equal exchange and two-way flow of urban and rural elements, promote the orderly flow of urban resource elements to the countryside, and enhance the vitality of agricultural and rural development.

　　The integration of urban and rural development is an important symbol of national modernization. In the process of industrialization and urbanization in China, a large number of factors of production flow from rural areas to cities, and cities have developed rapidly due to the accumulation of resource factors, while the development of vast villages has lagged behind due to the outflow of resource factors, which has caused problems such as unbalanced urban-rural development and insufficient rural development.

　　At present, the problem of insufficient imbalance between urban and rural development in China still exists, and the contradiction between urban and rural dual structure is still prominent, which has become one of the main obstacles restricting the integration and development of urban and rural areas in China.

　　Report to the 20th CPC National Congress, the Communist Party of China, put forward that priority should be given to the development of agriculture and rural areas, and the integration of urban and rural areas should be adhered to, so as to smooth the flow of urban and rural factors. Accelerating the integration of urban and rural development is not only the meaning of building a socialist modern country in an all-round way, but also the only way to achieve common prosperity.

　　The imbalance between urban and rural development is not sufficient, which is the inevitable result of the imbalance of urban and rural spatial structure and the unreasonable allocation of resource elements. To fundamentally break the institutional barriers that hinder the equal exchange and two-way flow of urban and rural factors, it is necessary to establish and improve the system and mechanism of urban-rural integrated development, promote more development factors and various services to the countryside, take the lead in breaking the dual structure of urban and rural areas in the county, and accelerate the equalization of basic public services.

　　To explore a new road of urban-rural integration and development, it is necessary to speed up the establishment and improvement of institutional mechanisms and policy systems conducive to the two-way flow of factors between urban and rural areas. It is necessary to improve the multi-input guarantee mechanism, increase investment in agricultural and rural infrastructure construction, accelerate the interconnection of urban and rural infrastructure, and provide support for promoting the two-way flow of talents, land, capital and other factors between urban and rural areas. It should be pointed out that rural development can not be achieved only by rural areas, but by promoting the orderly flow of urban resource elements to rural areas and enhancing the vitality of agricultural and rural development.

　　To explore a new way of urban-rural integration and development, and to smooth the urban-rural economic cycle, the core lies in developing county economy. Industrial revitalization is the top priority of rural revitalization and the starting point of practical work. In rural areas without industrial development, it is difficult for farmers to increase their income, which is not only difficult to gather popularity, but also difficult to attract talents. It is necessary to rely on the advantageous resources with rural characteristics, with the help of leading enterprises, family farms, new rural collective economic organizations and other main bodies to enhance the carrying capacity of counties in building agricultural industrial chains and characteristic industrial clusters, promote the new urbanization process through the development of county economy, and make up for the gap in the level of factor development between urban and rural areas.

　　To explore a new road of urban-rural integration, we should increase the supply of basic public services and promote the integration of urban-rural basic public services and social security systems. In recent years, China’s rural construction has achieved certain results, but the rural infrastructure is still not perfect, the level of public services is not high, and there are still many historical debts. In fact, the long-term imbalance in the allocation of public goods between urban and rural areas is one of the main reasons why the urban-rural dual structure is difficult to crack. Therefore, based on the inclusive characteristics of basic public goods, we should focus on rural basic old-age care, basic medical care and basic education, and narrow the gap between urban and rural basic public goods supply.

　　Urban-rural integration is a basic direction of future development, and attention should be paid to overall coordination and classified policies in the process of promotion. First of all, the flow of urban and rural factors involves many aspects, such as cities and villages, economy and society, population, resources and environment, etc. We should not make a sudden progress in policy guidance, but build a more systematic policy system to promote the free flow of urban and rural factors in a coordinated and efficient manner. Secondly, integration is not to eliminate the spatial functional differences between urban and rural areas, nor to pursue simple and uniform development, but to promote the complementary functions of urban and rural areas and smooth economic cycle by building a new type of urban-rural relationship, so as to achieve high-quality development in the coordinated progress of urban and rural areas.

　　In the use of pure electric vehicles, battery problems have been bothering many consumers. The difficulty in installing charging piles, long charging time and battery decay all affect consumers’ daily experience. In order to solve these problems, the power exchange mode came into being. Especially under the impetus of the policy, this year’s electricity exchange market is more lively. Since the first power exchange station of Chang ‘an New Energy was completed in Chongqing in September this year, power exchange stations from Geely and Dongfeng have successively landed or appeared in Chongqing, Jinan, Wuhan and other cities, breaking the situation that Weilai and BAIC were "equally divided" in the previous power exchange market. However, it is worth noting that it is nothing new that the battery replacement mode has already appeared. Behind the current lively situation, the constraints of profitability and battery specifications faced by the battery replacement mode remain unresolved.

　　▼ Policy spring breeze wakes up the rivers and lakes.

　　As the name implies, changing electricity means centralized storage, centralized charging and unified distribution of a large number of batteries through centralized charging stations, and battery replacement service for electric vehicles in battery distribution stations. Compared with the ordinary charging mode, the battery replacement mode can solve a series of problems caused by the difficulty of charging new energy vehicles, battery attenuation and easy spontaneous combustion, and the vehicle-electric separation mode adopted in the battery replacement can also effectively reduce the first purchase cost. This obvious advantage attracted many people to try layout more than ten years ago.

　　Image source Better Place Weibo

　　In 2007, Israeli Xia Jiaxi founded the first operating company, Better Place, which aims at changing electricity for passenger cars. However, the mode of changing electricity needs to lay a large number of power stations as the foundation, which is undoubtedly a "bottomless pit" for burning money in the early stage of operation. In 2013, Better Place declared bankruptcy and liquidation because it was difficult to balance the investment and income of the business model. At the same time in China, Dongfeng, Zotye, Kangdi, Nanjing Automobile and other companies also put a number of operating vehicles in the mode of changing electricity into the market, but they also did not stir up a splash.

　　Now, many years later, with the continuous expansion of the scale of new energy vehicles in China, the problems of charging difficulty and battery attenuation of pure electric products are becoming more and more serious. In order to solve the battery-related problems, the spring breeze of national policy has blown to the power exchange mode. In April this year, the "Notice on Improving the Financial Subsidy Policy for the Promotion and Application of New Energy Vehicles" jointly issued by the four ministries and commissions of the country clearly encouraged the development of the power exchange model; In May, after discussion and deliberation by delegates and members, the power exchange station was written into the government work report for the first time as an important part of the new infrastructure. Driven by the policy spring breeze, the domestic power exchange rivers and lakes are becoming more and more lively.

　　▼40 days, 3 car companies entered the game.

　　On September 10th, the first power exchange station of Chang ‘an New Energy was officially completed in Chongqing Olympic Sports Center. As a new heavyweight contestant after Weilai and BAIC, Chang ‘an New Energy Power Exchange Station has attracted great attention from the outside world. Generally speaking, the process of changing electricity mainly covers five steps: generating an order-entering the station-changing electricity-testing-leaving the station. Prior to this, the power exchange time announced by Weilai and BAIC remained at about 3 minutes, but the appearance of Chang ‘an New Energy Power Exchange Station refreshed this data. According to public information, Changan New Energy has reduced the time from battery taking to battery loading to 30 seconds, and the whole process from vehicle entering the station to battery replacement takes only 1 minute.

　　Geely Automobile also set a new record. A week after the completion of Chang ‘an New Energy Power Station, Geely Automobile’s first power station was officially unveiled at the 2020 Zhibo Fair and landed in Liangjiang New District, Chongqing. A month later, on October 18th, the second power station of Geely Automobile was put into operation in Jinan, Shandong. The data shows that Geely Power Station adopts a double-bin design, which can accommodate 39 battery packs, and can provide nearly 1000 power exchange services every day, and the power exchange time is about 90 s.

　　On October 19th, Dongfeng Motor’s intelligent power exchange station was also unveiled. At the 5th Science and Technology Innovation Week, after a Fengshen E70 (parameter | inquiry) drove into Dongfeng’s intelligent power exchange station, the vehicle was transported to the operation room by the conveyor and lifted, and the battery exchange robot automatically unloaded the old battery and installed the new battery. The whole process only took about 1 minute.

　　In just 40 days, the power exchange stations of the three major car companies have successively landed or appeared. Coupled with the paving of Weilai and BAIC, the prototype of the power exchange market has begun to appear. However, it is worth noting that even with the blessing of policies, the fundamental problem of the power exchange model-the contradiction between cost and profit-has not been solved.

　　▼ The contradiction between cost and profit is difficult to solve.

　　In the mode of power exchange, the separation of vehicle and electricity is an important link. Compared with ordinary pure electric vehicles, the battery cost of pure electric vehicles is no longer borne by consumers, and a series of risks such as battery attenuation are also transferred to the vehicle enterprises. These benefits enjoyed by consumers mean that car companies need to invest a lot of money in building power stations and buying batteries.

　　For example, Zhu Jiang, then vice president of Weilai Automobile, previously revealed that the daily operating cost of Weilai’s free power exchange was about 50,000 RMB. It has also been estimated by insiders that the average operating cost of each power station in Weilai is 400,000 yuan. From 2018 to now, Weilai Power Station has invested more than 500 million yuan. BAIC, which explored the power exchange market earlier, invested more. Wang Chunfeng, deputy general manager of BAIC Blue Valley Marketing Service Co., Ltd., said that in terms of power exchange station operation, the investment of a single power exchange station of BAIC New Energy is about 3 million yuan, but this figure is slowly declining.

　　Corresponding to the high cost is the uncertainty of profit prospects. At present, the power exchange in the market is mainly aimed at two groups, one is the private vehicles of ordinary consumers, and the other is the operating vehicles represented by taxis. Weilai, Beiqi New Energy, Chang ‘an, Geely and other enterprises have changed power stations, only Weilai’s power station is aimed at private users, while the latter three are mainly for taxis and network cars. In addition, in 2018, BAIC New Energy also released a battery-changing model called EU Quick Change Edition for ordinary consumers, but few people bought it.

　　In these two modes of operation, from 2018 to now, the number of power exchange orders for Weilai Power Station for private consumers has accumulated more than 1 million times. However, Weilai launched a lifetime free service for car owners, which means that the previous investment of 500 million yuan was a pure loss. Recently, however, Weilai has adjusted the policy of free power exchange: from October 12, 2020, users who pay big orders will be changed from unlimited power exchange to free power exchange for the first 6 times a month; Car owners who pay before October 12, 2020 still enjoy life-long unlimited free nationwide power exchange service. As for whether this adjustment can improve the profitability of the power station for Weilai, it still takes time to test.

　　As of June this year, 187 Beiqi new energy power stations for operating vehicles such as taxis have been built and put into operation in 19 cities across the country, with a total of 4.8 million power exchanges. However, in terms of profitability, BAIC New Energy and its partner Aodong in the field of power exchange have never been publicly disclosed. Aika Automobile found out from the announcement issued by BAIC Blue Valley (6.490, 0.04, 0.62%) when BAIC New Energy increased its capital for Aodong last year that the operating income of Aodong from January to April 2019 was 3,610,800 yuan and the net profit loss was 19,122,200 yuan. This means that among all the distribution power stations of AUTO, only a few power stations operating at full capacity have achieved profitability.

　　The picture shows the Aodong electric bar changing power station.

　　In addition to the difficulty in making profits, consumers have also encountered many difficulties in the process of using the power exchange service. "The pure electric taxi we drive can change electricity, but there are only thirty or forty power stations in Beijing. When we are running a sports car in the city, we often encounter the situation that the car has no electricity but the battery of the power station is not enough." Master Yang, a Beijing taxi driver, told Aika Automobile. It is understood that Master Yang’s "dissatisfaction with electricity" refers to the situation that the battery in the power station is not fully charged. Generally speaking, each power station will be equipped with thirty or forty batteries, but when the power exchange vehicle exceeds the upper limit of the power exchange station, the batteries of the power exchange station will be replaced by the power exchange vehicle before they are fully charged. When Aika Automobile met Master Yang at a power station in Haidian, there were already eight taxis waiting in line to change power.

　　▼ Scale is the key to breaking the game

　　"In order to optimize the power exchange experience and achieve profitability, it is not enough for enterprises to fight alone." Regarding the contradiction between high cost and profit prospect, and the "power shortage" encountered by Master Yang, an industry expert told Aika Automobile that the "power shortage" was mainly caused by the imperfect network layout of power exchange stations, and the imperfect layout of power exchange stations was caused by the excessive investment of a single power exchange station, which was difficult for enterprises to bear. Only by changing the number of power stations can the consumer experience be optimized and improved; Only when the number of electric vehicles increases, can we bring enough passengers to each power station, and the power station can achieve profitability. The two are complementary and interlocking. "

　　The losses of Weilai and Beiqi New Energy Power Station prove that enterprises only serve their own products to change electricity, and it is difficult to achieve profitability. At the same time, if every enterprise invests a lot of cost to lay the power station network, it will not only be difficult for enterprises, but also waste resources for the whole society. In the expert’s view, only when the car companies combine Lian Heng in power exchange and the overall market forms a scale effect can the problem be fundamentally solved.

　　Chang’ an’s mode of changing power stations is based on this idea. Aika Automobile understands that by joining hands with partners such as Contemporary Amperex Technology Co., Limited, Aodong, State Grid and Iron Tower, Chang ‘an New Energy Power Exchange Station can support the power exchange services of seven major automobile companies such as BAIC, GAC, SAIC, FAW Hongqi, Pentium, Dongfeng Qichen, Chang ‘an and Jianghuai, which means that the power exchange station will have higher turnover rate and profitability.

　　But for the whole market, this model also means a new round of competition for the right to speak. "If you want to realize the universal interchangeability of batteries in many enterprises, you must formulate a unified battery specification. Whoever formulates this specification will occupy a dominant position in the new round of power exchange market. " The expert said, "If you want to continue to develop the power exchange mode, more and more car companies will cooperate, and the standard dispute of pure electric batteries will soon appear. At the same time, this debate is not limited to car companies, and charging operators are also important players in the power exchange market. Whether this standard is customized by car companies or formulated by charging operators also determines the right to speak in the battery field. "

　　In fact, despite the warmth of policy spring breeze, there are still a lot of problems for car companies to promote the development of power exchange mode. In addition to a large amount of capital investment, the cooperation between enterprises at the same level, the unification of battery specifications, the acceptance of consumers and the future dispute over the right to speak are all issues that need to be considered.

　　Since the beginning of this year, the Finance Bureau of Chengde City, Hebei Province has focused on standardizing the procurement process management, making full use of standardized template methods, focusing on three aspects of work, and promoting the scientific, accurate, transparent and efficient development of government procurement in the city.　

　　The first is the standardization of the preparation of the procurement plan demand plan.On the basis of fully implementing the electronic filing of government procurement plans, Chengde Finance Bureau issued the Notice on Standardizing the Planning of Government Procurement Plans according to the relevant requirements of Hebei Provincial Department of Finance, which put forward detailed requirements on internal control management, capital requirements, demand review, policy implementation, contract management, performance acceptance, etc., and made a planning template, and the purchaser made multiple-choice questions or fill-in-the-blank questions one by one according to the actual project to improve the planning of procurement plans.　

　　The second is the standardization of filing materials for government procurement plans.In view of the different situations involved in the filing, review and approval of government procurement projects, Chengde Municipal Finance Bureau has separately compiled the One-time Notice of Government Procurement Plan Filing, the One-time Notice of Government Procurement Import Product Auditing and the One-time Notice of Government Procurement Plan Approval, so as to clarify the materials required for filing of procurement plans of various procurement projects. All procurement projects in Chengde have been upgraded from paper filing to electronic filing and then to one-time standardized electronic filing. The purchaser can complete the preparation and filing of procurement plan requirements within 1-2 working days after completing the investigation and review of procurement requirements, and the procurement efficiency is obviously improved.　

　　The third is to optimize the standardization of business environment policy implementation.In order to further compact the purchaser’s main responsibility, strictly implement the government procurement policy, strengthen the preparation of procurement documents, and determine the qualification conditions of suppliers according to laws and regulations, Chengde Finance Bureau began to implement the commitment system for optimizing the government procurement business environment policy on August 1 this year, and produced the Commitment for Optimizing the Government Procurement Business Environment Policy, which requires the purchaser to strictly implement it before carrying out procurement activities, and the main person in charge of the unit makes a commitment to ensure the full implementation of the policies for optimizing the business environment from the source.　

State and municipal people’s governments, provincial committees, offices, departments and bureaus:

-The supporting capacity of high-level all-optical networks has been further enhanced. The total bandwidth capacity of the Internet out of the province is 40T, the gigabit broadband coverage rate of key places is 100%, the broadband access capacity of administrative villages is more than 100 megabytes, and the fiber access rate of natural villages (more than 20 households, the same below) is 75%.

-Accelerate the construction of advanced ubiquitous wireless networks. The optimization of 4G network has achieved remarkable results. The boutique tourist routes in go on road trip and the tourism ring road in western Yunnan have achieved 4G network coverage, and the effective coverage rate of 4G network in natural villages has increased to 90%. There are 56,000 5G base stations, creating a 5G boutique network, fully supporting the highlights of converged application demonstrations, and gradually achieving continuous coverage of 5G networks.

-application infrastructure has been further consolidated. Build a high-level Internet of Things, and enhance its support for intelligent manufacturing, artificial intelligence, smart agriculture and industrial parks. Promote the transformation and upgrading of the internal and external networks of industrial Internet enterprises, carry out the construction of public service nodes for identification and analysis of provincial industrial Internet, and realize interconnection with top national nodes.

-Great breakthroughs have been made in the international communication hub business of radiating South Asia and Southeast Asia. Improve and optimize the network structure, and add the direction of China and Vietnam to cross-border optical cables. Accelerate the expansion of international value-added services and government-enterprise special line services. We will build a dedicated channel for Internet data and promote the implementation of regional Internet transfer services.

Second, the main task

(A) to build a high-level all-optical network

1. Accelerate the optimization and upgrading of the backbone network. Promote the integration of national trunk lines and provincial trunk lines, realize the one-hop direct connection of large-bandwidth circuits between states, cities and backbone networks, reduce transmission delay, and provide a highly reliable bearer network for 5G. Continue to increase the direction and routing of optical cables out of the province, and improve the network carrying capacity and the inter-provincial export bandwidth of the Internet. Carry out grid evolution of backbone transmission network. In 2021, the total bandwidth capacity of the Internet will reach 40T.

2. Promote the construction of gigabit broadband. Give priority to the deployment of Gigabit broadband access networks in the urban economic circle in central Yunnan and tourist cities such as Dali, Lijiang and Xishuangbanna, gradually expand the coverage, and organize the special action of "double promotion" of urban and rural broadband. Promote the development of education private network and medical private network from 100 megabytes to gigabit. We will upgrade and transform broadband access network capabilities, accelerate the construction and deployment of 10G industrial passive optical networks (PON), and gradually form users’ universal access to Gigabit broadband networks. In 2021, the coverage rate of gigabit broadband in key places such as transportation hubs, schools, hospitals and major industrial parks will reach 100%.

3. Build a rural 100-megabit optical network. Promote the special action of "double promotion" of urban and rural broadband in rural areas, effectively narrow the gap between urban and rural areas, and strive to achieve the same speed on the same network. In 2019, the broadband network access capacity of administrative villages reached more than 100 megabytes. Guide telecom enterprises to gradually reduce broadband access fees for rural e-commerce and industrial poverty alleviation in poor areas, and continuously improve the utilization rate of broadband network resources in poor areas.

2. Build a new generation of green data center. Make full use of the advantages of Yunnan’s location facing South Asia and Southeast Asia, abundant clean energy and cool climate, and strengthen the planning and layout of building a new generation of green data centers. Significantly reduce the electricity cost of large data centers (IDC), guide enterprises such as national websites, big data and cloud computing to choose IDC access in Yunnan, and explore the construction of an international Internet application data center in China (Yunnan) Pilot Free Trade Zone. In 2021, 10,000 new racks will be built.

3. Accelerate the construction of industrial Internet infrastructure. Accelerate the construction of high-speed, low-delay, safe, reliable, flexible networking and time-sensitive industrial Internet. Promote the transformation and upgrading of internal and external networks of enterprises, and build an industrial Internet with high reliability, low delay, large bandwidth, wide coverage and customization. Optimize and upgrade the backbone network, and initially complete the IPv6 transformation of interconnection nodes between networks. Carry out the construction of public service nodes for identification and analysis of provincial industrial Internet, and realize interconnection with top national nodes. Explore the application of technologies based on 5G, NB-IoT, PON and industrial wireless in industrial sites in key industries, and build a number of benchmark demonstration networks for industrial intranet/extranet.

4. Improve the service ability of the network to support economic transformation and upgrading. Guide basic telecommunications enterprises to provide differentiated service solutions from network support to tariff concessions for industrial parks, high-tech industrial development zones and small and medium-sized enterprises. Promote the application of network slicing technology and adapt to various types of applications as needed.

(5) Promoting the construction of an international communication hub.

1. Build an international communication infrastructure for South Asia and Southeast Asia in an all-round way. Expand the export bandwidth of international communications, further improve and optimize the network structure, and accelerate the construction of cross-border optical cables. Complete the multi-route transformation of Ruili (China-Myanmar) and Mengla (China-Laos) international export channels and international optical cable export, build a new Hekou (China-Vietnam) international optical cable and transmission system, and set up a new China-Vietnam international channel import and export bureau to improve the level of international communication interconnection. In 2021, the international export bandwidth reached 3.4T.

2. Build a direct international Internet information "highway". We will promote the construction of dedicated channels for Internet data to Beijing, Shanghai and Guangzhou, and greatly improve the performance of Internet access. Improve the ability to unblock international voice services and Internet transfer services in Yunnan, South Asia and Southeast Asia, and promote the implementation of regional Internet transfer services. Focus on South Asia and Southeast Asia, provide large-capacity information network support for international trade enterprises, strive to build Kunming into a regional export hub for international communication services in China, and strengthen Yunnan’s position and role as a radiation center for international information hubs in South Asia and Southeast Asia.

(6) Strengthen the security of cyberspace.

Adhere to the combination of "technology management" and improve the security protection capabilities of new technologies and services such as 4G, 5G, industrial Internet and Internet of Things. Implement network security systems such as network security level protection and risk assessment, strengthen the "three synchronizations" of network security facilities, and promote telecom enterprises and Internet enterprises to strengthen the capacity building of network security situational awareness. Enhance the ability of emergency communication support system and strengthen the construction of emergency communication support team.

III. Implementing the Project Plan

(1) Fill the shortcomings in the development of information and communication infrastructure (2019)

Improve the quality of broadband and wireless network coverage, optimize the layout of information application infrastructure, promote the construction of international communication hubs, and fill the shortcomings of development. (See Table 1 for details)

(2) Building high-quality information and communication infrastructure (2020)

"From point to area" made a comprehensive breakthrough, improved the network carrying capacity and inter-provincial export bandwidth of the Internet, accelerated the deployment of gigabit broadband networks, and the coverage rate of gigabit broadband in key places reached 40%. Improve the service level of 4G network, build a 5G boutique network, realize continuous coverage of 5G network in some key areas, and promote the "5G+" application demonstration. Further enhance the ability of application infrastructure and accelerate the construction of international communication hubs and dedicated channels for Internet data. (See Table 2 for details)

(3) Improve the capacity of information and communication infrastructure as a whole (2021)

We will build a high-level broadband network, comprehensively improve the carrying capacity of backbone networks and the inter-provincial export bandwidth of the Internet, and deploy gigabit cities on a large scale, with a gigabit broadband coverage rate of 100% in key places. Further strengthen 4G deep coverage and improve network quality. Achieve continuous coverage of 5G networks and fully support the integrated applications in all fields of society. Improve the application infrastructure capacity in an all-round way, and complete the construction of an international communication hub and a dedicated channel for Internet data. (See Table 3 for details)

Fourth, safeguard measures

(A) to strengthen organizational leadership, the establishment of collaborative promotion mechanism.

A leading group for coordinating the construction of information and communication infrastructure was established, headed by the deputy governor in charge, and composed of functional departments such as communication management, industry and informatization, development and reform, finance, housing and urban-rural construction, natural resources and ecological environment, and basic telecom operators. The office of the leading group is located in the Provincial Communications Administration, which takes the lead in promoting the project construction, implementing the decision-making matters of the leading group and coordinating the work of various departments. Each state and city shall establish an organization, leadership and coordination mechanism.

(B) increase fiscal and tax support to reduce energy costs.

Give full play to the policy-oriented role, take advantage of the opportunity of the national pilot implementation of universal telecommunications service, strive for central subsidy funds, and increase support for the construction of rural remote areas in our province. Coordinate financial funds to support the construction of 5G base stations and the integrated application of advanced network technologies such as 5G and Internet of Things in digital towns, industrial parks and key industries. Support innovative project financing mode, encourage and guide social investment, and realize investment diversification. Make full use of preferential tax policies, and eligible enterprises can enjoy preferential tax policies such as high-tech enterprises, software enterprises and the development of the western region. Power enterprises should strengthen the power supply network to ensure the stability of power supply. We will implement preferential policies for the good use of electricity, open market access for basic telecommunications enterprises, support enterprises to participate in electricity market transactions, and reduce energy costs.

(3) Simplify the approval process and strengthen resource sharing.

Relevant departments should open up a green channel, handle the examination and approval of land use and electricity use and land title certificate for information and communication infrastructure projects, simplify the examination and approval procedures, and reduce or exempt relevant fees in accordance with regulations; Government agencies, administrative institutions, state-owned enterprises, universities, residential areas, airports, stations, subways, exhibition halls, tourist attractions and other affiliated buildings, as well as street lamps, road signs and other public facilities are free to open. Promote the co-construction and sharing of urban and rural information and communication infrastructure, basic pipelines of special communication networks such as electric power, transportation, water conservancy and education, and various base stations. Promote the co-construction and sharing of power tower resources while ensuring the safe operation of the power grid. Promote the simultaneous supporting information and communication infrastructure for residential areas, subways and other construction projects, and implement the construction of communication pipelines, towers, rooms and other supporting facilities within the building red line. It is forbidden for any institution or individual to obstruct the construction of information and communication facilities without reason or charge unreasonable fees.

(4) Strengthen coordinated promotion and strengthen policy implementation.

The people’s governments of all prefectures and cities should take the construction of information and communication infrastructure as a key task, combine it with the implementation and work promotion of relevant documents such as digital Yunnan, digital countryside, industrial Internet, artificial intelligence, and 5G application, decompose the construction tasks year by year, regularly study relevant matters, and effectively help the construction unit solve the problems of difficult base station location, pipeline laying, and demolition compensation. The Provincial Communications Administration and the Provincial Department of Industry and Information Technology set the annual construction task objectives, and jointly with relevant departments, timely report the implementation of key tasks and supporting policies in the action plan.

(5) Strengthen publicity and training to create a development environment.

Provincial Communications Administration, Provincial Department of Science and Technology, Provincial Department of Ecology and Environment and other departments organized the popularization of electromagnetic radiation from base stations covering all states, cities, counties and districts in the province to eliminate people’s doubts and misunderstandings about base station radiation. Relevant departments should publicize the effectiveness of infrastructure and create a good atmosphere for the construction of information and communication infrastructure.

Press Conference of Yunnan Provincial People’s Government Press Conference of Three-year Action Plan for Information and Communication Infrastructure Construction in Digital Yunnan (2019-2021)

The story should start with a family dance competition.

In the future, these competitions will be held online, and families will be divided into three groups and four groups.

Jack’s family is a foursome.

Father, mother, brother, sister, members gathered together and loved each other perfectly.

But … wait.

Father is white, mother is black and two children are yellow?

This family composition is complicated enough.

More complicated.

At the end of the game, Jack’s family lost.

However, the son (Yang)’ s hand still kept waving and waving.

He actually … crashed! ! !

Yes, literally, my son turned out to be a robot!

From cross-racial to cross-biological, Sir is more and more curious. Where will this story go?

Yanghou

After Yang

After Yang, a new film A24, is adapted from the short science fiction novel Say goodbye to Yang.

Yang, the hero of the movie, is a robot set as a boy in China.

American movies, Korean directors, China protagonists and China culture collide to produce wonderful chemical reactions.

"Fruits of Summer" and "Everything about Lily Zhou", all kinds of popular elements, dream back to twenty years ago at any time.

On the surface, the film is still about robots.

But under the fusion of various new elements, this time, the director wants to express more than "the relationship between robots and people".

01

breakdown

Tell the story back.

Jack’s family are all worried about Yang’s crash.

Yang is an outsider in this family.

When Jack bought Yang, it was to accompany his yellow-skinned daughter Mika to grow up, so that she wouldn’t be upset because of her different skin color from her parents. -Mika is actually adopted.

The severance of blood relationship and emotional alienation make the word "home" more ambiguous.

For many years, Yang taught Mika Chinese and told her about China culture.

Mika, on the other hand, has always called Yang "Brother" in Chinese.

The family is very dependent on Yang.

Yang is good everywhere, but the quality is not good.

Strange to say, jack was greedy for cheap.

To buy Yang Shi, he did not buy it directly from the official company, but from an agency.

It means that Yang is not brand new, but has been returned to the factory to be rebuilt.

The buyer told him that Yang had only been used for five days, but it could save a lot of money for their family.

There is no such thing as a "free lunch".

Sure enough:

Yang suddenly shut down without warning.

Mika cried for her brother.

Jack and his wife Keira had to bite the bullet and continue their lives.

But the situation is far more difficult than they thought.

I found the agency that bought Yang in those days and ran away early.

Find the official repair point of the original company, and people say that the parts are all normal, but the bad part is the core fault, which can’t be repaired.

So, Jack looked for various methods.

Beyond all legal forms and commercial terms, ask for help from robot researchers in exchange for his maintenance on the condition of studying Yang.

Salvation is the motive force at the beginning of this story. They tried their best to save Yang, and at the same time, they were also saving the family.

However, the title of the film, as you know, is Queen Yang.

In fact, a more accurate translation is After the Death of Yang.

02

secret

After Yang is a very soft soft science fiction.

As a robot, Yang has neither super power display nor dazzling technology embodiment. Remove the element of artificial intelligence, and you can even treat him as an ordinary person.

This is the director’s intention.

Look at Sir.

The background color of Queen Yang is like a mourning film wrapped in quiet sadness.

At the beginning of the film, Yang died.

The rest is just a long farewell.

In many movies, we can see this "routine", that is, the more familiar we are with the person, the more we can understand this person after his death. Diary of the Sea Street and Long Farewell …

After Yang is no exception.

Yang has always been a perfect robot.

He has a high IQ and can communicate freely with human beings. Gentle personality, take care of the family in every way.

Rich in knowledge, just like a walking museum of Chinese culture.

Especially when Jack and Keira are busy at work, he is an indispensable good helper.

Yang is like a member of a traditional family who works hard and is extremely dependent on everyone.

But one day, the family suddenly lost him.

Everyone was caught off guard.

Jack opens Yang’s memory bank, which contains an image he recorded every day.

Like entering a secret forest, unknown.

Mika’s growth record.

And Yang’s own smile in the mirror.

Huh? Why is there a strange girl?

The memory fragments like the stars of Yang are accompanied by the family’s memories of Yang.

His image is gradually three-dimensional and complicated.

It turned out that they ignored so much.

He can think for himself.

Taking a family photo, Yang fiddled with the camera and watched his family call him over. Yang suddenly lost his mind for a moment.

At that moment, he was probably thinking about what he meant to this family.

He will still fall in love.

Jack found the girl that Yang stored in his memory through various clues.

Only then did I know that he would strike up a conversation with a girl he likes, date her and talk on the phone like a human being.

And then along more memory storage fragments.

Jack found out.

He is their Yang, not just their Yang.

The stories he has experienced and the emotions he has are far more complicated than the Jack family imagined.

Yang is a robot that has experienced several generations.

The cello version of "Fruits of Summer" quietly sounded after the family got to know Yang again.

The melody is sad, but here, Chinese can feel it better.

How relevant the lyrics of its Mandarin version are.

"Maybe giving up can get close to you."

"The accumulation of time, the fruit of this midsummer, the lonely fragrance in memories."

On the surface, the director is talking about the relationship between man and artificial intelligence-whether AI has feelings or not, and human beings don’t know the secrets of AI enough.

But in fact, what the director wants to examine through AI is human’s own consciousness and emotion.

When we maintain our image, form a family and integrate into a large group, do those barriers really disappear?

You vaguely feel that something is wrong, but you can’t tell where it is.

In other words, everywhere.

03

minority

According to the data of the US Census Bureau in 2020, among the more than 300 million people, whites only accounted for 53%.

Of the rest, 18% are Latino, 13% are African-American … and Asians also account for 5%.

True to its name, it’s a multi-ethnic melting pot.

The future society built by Queen Yang is a huge diversified melting pot.

In addition to the protagonist family, white people, black people, Chinese people and robots.

And, human cloning.

The film spent a lot of time talking about the differences and barriers of various identities.

"Identity" is the key to understanding movies.

The two plots are meaningful.

Conversations from Yang and "Father" and "Mother" respectively.

First, Jack and Yang discuss China tea.

When Jack talks about tasting tea, it feels like walking through the forest after the rain, and the scene is all in a cup of tea.

He also taught Yang to smell tea, saying that he could smell history from the inside.

He forgot.

Imagination and synaesthesia seem to be the privileges of human beings.

But then, Yang described another beauty of tea in his eyes from the perspective of his "robot".

Tea blooms and floats in the water.

I hope to know more about tea.

I hope I have a true memory of China tea.

At that moment, it seemed a little beyond Jack’s cognition.

He subconsciously asked the basic question to test "Are you a human or a robot": Are you happy?

Yang replied, I don’t know if this is a problem for me.

A delicate game.

The other is that Keira and Yang talk about death.

Yang said, even if life is nothing after the end, I can accept it.

Keira was obviously shocked to hear such words from a robot population.

Like Jack, she asked Yang, Will you feel sad?

Happy, sad.

People always use their own emotional standards to measure everything.

Just like after Yang’s "death", Jack asked his clone girlfriend if Yang had ever suffered for being a robot and wanted to be human.

Yes, after all, in the concept of human beings, in countless works about robots, they all want to become human beings and even replace human beings.

But the girl laughed after hearing it: this is the question that human beings ask.

We are all familiar with the tradition of China, and we all know the story of "a child is not a fish". Yang has always said "Zhuang Zhou Meng Die", but no one really understands the meaning of these two stories.

On the surface, what we are discussing here is the identity of human and non-human, but in fact, under the shell of biological dialectics, everyone is confused in reality.

Namely:

What is me?

We miss live high, but we often materialize our lives.

By wealth, by status, by knowledge, by skin color.

Even robots are unconsciously enslaved.

In the movie, Yang often asks his girlfriend:

Are you Chinese? What are the characteristics of Asians?

This is because.

His sister, as the daughter of Chinese, is often asked about her biological parents by her classmates at school, which hurts her very much.

Asians and Americans, robots and people, the corresponding relationship designed here is very clear.

To put it bluntly, Asians still exist in a weak position in a seemingly mixed and diverse environment.

Which is what we call a minority.

Reject the label and you will be marginalized.

But if you erase the label and go into the mainstream, you may also lose your "self".

This is probably the confusion that Guo Gongda, as a Korean director, really wants to express.

Later Yang figured it out.

I don’t want to live in the perfect narrative of others.

He used "grafting", a technology invented by Chinese thousands of years ago, as a metaphor for the fate of the brother and sister.

A branch is taken from one tree and grows together with another tree.

That’s all it is.

Mika blurted out:

"It’s just pretending to be part of this tree."

Yang said, "Doing so can create new things."

An almost beautiful and extravagant hope.

Because we are well aware that the 23 million Asian population in the United States will still face more or less discrimination at a time when different groups are increasingly divided and conservative, and misunderstandings and conflicts are surging.

However, After Yang believed in hope.

In the process of saving Yang and re-understanding Yang, the family finally reached some kind of emotional redemption and perfection.

This is the value of "After Yang".

It’s not a rush to smooth out the differences.

To tell you honestly, the difference is there, and the gap may not disappear completely.

But those most universal and sincere feelings are always the channel to understand another language and another existence.

Just like Mika came to Yang Zeng’s room in immature Chinese and said goodbye to him.

Just like his girlfriend lying on Yang’s chest, as if he still had a heartbeat.

You can think of him as AI.

But if you read it out gently:

It is love.

The picture in this article comes from the Internet.

Editor’s Assistant: M is the murderer.

Have you noticed that there has been a lot of good news from operators recently?

It is also a port number transfer network, and it is also vying to get on VoLTE.

One of them, Xiao Lei, has been waiting for a long time-the mobile phone number supports remote account cancellation.

This policy not only saves time but also saves money. (After all, the trip home can cover your phone bill for several years.)

Yes, you heard me right.

From January 1st this year, all three major operators can cancel their accounts in different places.

Xiaolei wants to praise Unicom most, and he went online to cancel his account early, so we don’t have to run the business hall again.

As for mobile telecommunications, it is a little more difficult.

Last week, Mobile began to pilot online account cancellation. But if you open China Mobile App, you probably can’t find the account cancellation entrance, because it is only limited to Shaanxi Mobile number for the time being.

Mobile number and telecom users in other areas can only go to the business hall to handle it.

(account cancellation entrance: China mobile App→ classification → life → online sales number)

Lei doesn’t know when it will be open to the whole country. Before that, mobile phone users should take a look at the preparations first …

Method for cancel number of mobile telecommunication in different places

Listen, to cancel the number in the business hall, you need:

I bring my ID card and service password and go to the designated business hall to handle it.

Not all business halls can do it.

Take Guangzhou, where Xiaolei is located, as an example. Only the business hall can close the account in different places.

(An authorized agency like this won’t do)

So before you go, be sure to call 10086/10000 to find out which business halls can do it.

But, you can’t just cancel it if you go.

Your mobile phone number cannot have the following conditions:

Arrears;
Have a contract;
It is bound with services such as family number and broadband.

Only one situation:

At the time of inquiry, Xiao Lei found a secret, and the method of canceling the account between Mobile GSM and M-Zone Shenzhouxing was actually different.

The customer service explained this to me:

You must go to the business hall to make an appointment to cancel your account. If you don’t pay for the next 90 days, you will automatically sell the number;
And Shenzhouxing and M-Zone will automatically cancel the number if the arrears exceed 90 days.

You don’t pay your phone bill for 90 days. How can there be such a big difference?

Under the coercion of Xiao Lei, the customer service told Xiao Lei:

Because GSM is prepaid, arrears will affect credit, so you have to make an appointment to cancel your account;
However, Shenzhouxing and M-Zone are post-paid, and how much is charged, even if the arrears are directly thrown away, it will not affect the credit.

In other words, Shenzhouxing and M-Zone don’t have to go to the business hall to close their accounts.

Fortunately, little ray asked, and saved you another thing?

In a word, Xiao Lei suggests that you call 10086/10000, where you belong, to find out your account cancellation conditions, so as not to make a trip in vain.

If there is a Shaanxi mobile phone friend who is reading this article, the account cancellation process on the mobile App is similar to that of China Unicom, and Xiao Lei said it together.

Unicom remote number cancellation method

Xiao Lei cancelled a Unicom number in January.

The entrance is easy to find:

"Mobile phone business hall App → service → handling → account cancellation"

First of all, we have to go through the triple verification of "SMS verification code+uploading ID photo+face recognition". The ID card must be taken now, and photos in the photo album cannot be used.

I can’t help it. I have to prevent others from maliciously canceling your number.

At this time, China Unicom will remind you that the phone bill should not be less than 50 yuan, otherwise it may not be possible to cancel the account ~ (Mobile can cancel online as long as it does not owe money at that time)

In order to close the account successfully, Xiao Lei gritted his teeth and charged the phone bill again.

Of course, the extra money will be refunded to you.

It is only by transferring to the balance of another Unicom number in the same province.

For example, the number of Xiaolei Guangdong Unicom cannot be transferred to Jiangsu Unicom.

Just when I crossed my heart and thought I was done, huh? ? ? Unknown error. What the hell? !

Ray suddenly felt struck by lightning.

No way, find customer service! When I opened Unicom official website and found that there were only two people waiting in line, Lei was secretly pleased.

The problem is that miss customer service can’t solve the problems that Xiaolei encountered, and finally she just gave a complaint feedback link …

Just when Xiaolei was disheartened, ready to give up and went directly to the offline business hall to cancel the account, he suddenly had a flash of light and thought of the key to the problem: Unicom’s mobile phone card number is divided into 4G and 2 G and 3 G.

Generally, 4G numbers belong to China Unicom’s national system CBSS, while many 2 and 3G numbers still belong to local provinces and cities BSS. The two card systems are not connected, so naturally they cannot be transferred.

And the number I want to transfer to is the 3G card!

Sure enough, Xiao Lei changed the number to a colleague’s 4G card, and it was a success.

Almost a month later, the balance was directly charged to the number I filled in.

In addition, Unicom also provides a way that it likes very much-just don’t.

However, if you want cash, you can do it. You have to go to Unicom’s own business hall to cancel the number, and support bank card transfer to refund the balance.

It should be noted that the donation fee is non-refundable, and only the money that you recharge can be refunded.

In contrast, the refund of mobile telecom is very pit.

Lei asked the customer service:

At present, there is no uniform standard for telecommunications, and whether cash can be refunded depends on local policies;
Mobile can only transfer the balance to the mobile number of the same attribution, and cannot refund cash.

Although mobile tries to save the user churn rate by raising various thresholds.

But now there is a remote account cancellation+port number transfer, and it is not a simple matter of who we want to use.

I asked if you were afraid.

Wait a minute! Don’t go after reading the article!
