　　Snowflakes are fluttering in the north and rainy in the south. On the 14th, the largest range of rain and snow weather since winter came online. What is the reason for the rain and snow? What will the weather be like in the future? The reporter interviewed relevant experts.

　　The snowfall in the north has a large impact range and strong intensity.

　　Fang Yi, chief forecaster of the Central Meteorological Observatory, said that around the 14th, the snowfall in the north was generally characterized by a large impact range and strong intensity, which was the largest and strongest snowfall in North China since winter. There are small to medium snow or sleet in central Inner Mongolia, Hebei, Beijing, Tianjin, Henan and other places, which gradually weakens after nightfall that day. Snowfall in Liaoning, Shandong and eastern Inner Mongolia will last until the morning or day of the 15th.

　　Just two days ago, the snowfall on the 12 th has already surprised many small partners in the north. It is also snowing, but the snow on the 14th is somewhat different from that of the previous days.

　　Fang Yi pointed out that the difference between the two snowfall processes lies in the different sources of cold air and water vapor. This round of snowfall is due to the continuous eastward movement of cold air in northern Xinjiang and southward along the northwest road. Before the influence of cold air, the ground inverted trough and the low-level southerly wind were significantly strengthened, which transported the warm and humid airflow from the south to the north, which was beneficial to the formation of snowfall in Huanghuai area of North China. On the 12th, the snowfall process was mainly caused by the return of cold air from the East Road. In addition, there was an easterly wind in Bohai Sea to transport water vapor, which led to snowfall in Huanghuai area of North China.

　　Strictly speaking, the snow on the 14th was the third snowfall in Beijing recently. Not only that, since February, there has been obvious snowfall in many places in the north, including Beijing.

　　Chen Lijuan, chief of the Climate Prediction Office of the National Climate Center, said that the precipitation situation is closely related to the coordination of cold air activities, water vapor transport and other conditions. In February, there were two strong cold air processes affecting China. At the same time, the subtropical high in the western Pacific is stronger than normal, and it is north by west, which leads a lot of water vapor from the northwest Pacific and the South China Sea to be transported to China, especially to the north of the Yangtze River, where it merges with the cold air guided by the trough from Mongolia to Northeast Asia, forming favorable conditions for precipitation in the north. Because the temperature is obviously lower than normal, it appears in the form of snowfall.

　　The continuous rain in the south has lasted for a week.

　　Since February 7th, there has been continuous rainy weather in southern China for one week. Fang Yi said that due to the strong and stable subtropical high, the south branch trough is more active, the low trough keeps moving eastward, and the warm and humid airflow is strong, resulting in continuous rainy weather in the south.

　　He said that in the coming week, there will be continuous rainy weather in Jiangnan, South China, Jianghuai, Jianghan, Chongqing and Guizhou. In particular, it should be noted that from 17th to 18th, heavy rain may occur in parts of central and western South China and central and western South China, and the possible secondary disasters should be prevented in time.

　　Fang Yi pointed out that for the northern region, Xinjiang, Tibet, Qinghai and other places will have small to medium snow, local heavy snow or blizzard from 14th to 16th. Around the 18th, there will be a snowfall mainly with light snow in south-central North China, Huanghuai and other places, and moderate to heavy snow may occur in some areas of Huanghuai.

　　Chen Lijuan said that from December 1, 2018 to February 13, 2019, the national precipitation was 29% higher than the normal average, but the spatial distribution was extremely uneven. The eastern region was "less in the north and south, more in the middle", that is, less in the northeast, north China and eastern South China, but more in Jianghuai and Jiangnan, and more in the western region as a whole.

　　Ruixue is a good year, especially for the northern region. Because of less precipitation in the early stage, snowfall is very beneficial to alleviate drought and agricultural production. However, the continuous rainy weather in the southern region will affect the growth of crops to a certain extent.

　　The global climate is closely related, and El Ni? o "adds fuel to the fire"

　　Looking around the world, not only has there been precipitation in many places in China recently, but there have also been frequent snowstorms in Europe and the United States.

　　Chen Lijuan pointed out that Europe, influenced by the Atlantic warm current, belongs to a temperate maritime climate, and the water vapor conditions are still abundant in winter, which is favorable for precipitation. If cold air from the polar regions moves southward, it is easy to form snowfall. Influenced by the water vapor transport conditions in the western Atlantic Ocean and the eastern Pacific Ocean, the United States is also prone to heavy snowfall when it encounters strong cold air activities. From January 26 to 30, the polar vortex invaded the United States southward, and two-thirds of the United States suffered from extremely cold weather, and the temperature dropped to the lowest in many years.

　　She said that from the global climate background, since September 2018, the tropical Middle East Pacific has entered an El Ni? o state, which will form an El Ni? o event, which is conducive to transporting more tropical ocean water vapor to the southern United States. El Nino event has no direct contribution to the cold wave in North America, but when the cold wave occurs, if more water vapor is transported to the mainland of the United States, it will easily lead to heavy snowfall, thus aggravating the disaster and influence of cold wave activities.

　　At the same time, when El Ni? o occurs, it is beneficial to transport more water vapor from the western Pacific Ocean and the South China Sea to China’s land areas, creating conditions for precipitation in the eastern part of China, and cooperating with the process and intensity of cold air activity in the middle and high latitudes, causing rainfall or snowfall in different parts of China.

The first commodity was named lifan 520. On March 3, 2014, Iranian state-owned automobile industry manufacturers held the exit ceremony of Lifan automobile assembly production line, which meant that Lifan automobile’s assembly car manufacturing in Iran was fully launched.

　　The 14th Five-Year Plan for the Development of Big Data Industry recently released by the Ministry of Industry and Information Technology (hereinafter referred to as the Plan) proposes that by 2025, the estimated scale of China’s big data industry will exceed 3 trillion yuan, and a modern big data industry system with strong innovation, high added value and independent control will basically take shape.

　　When interpreting the Plan, China Information and Communication Research Institute and China Electronic and Information Industry Development Research Institute pointed out that digital industrialization supports industrial digitalization, and industrial digitalization drives digital industrialization. The Plan systematically lays out the new stage to promote the high-quality development of big data industry. We must seize the opportunity and push the development of big data industry to a new level.

　　Big data industry ushers in a broader development space.

　　Xie Shaofeng, Director of the Information Technology Development Department of the Ministry of Industry and Information Technology, said that the "14th Five-Year Plan" period is a crucial period for China to accelerate the construction of a manufacturing power, a network power and a digital China, which puts forward new and higher requirements for the development of the big data industry, and the big data industry will enter a new stage of integrated innovation, rapid development, in-depth application and structural optimization. He said that data has become the fifth largest factor of production after land, labor, capital and technology. The value of data elements is reflected in two aspects. One is that data is the "oil" in the digital economy era, and the other is that data is the "diamond mine" in the digital economy era.

　　According to the Plan, during the 14th Five-Year Plan period, the development of big data industry should focus on promoting high-quality development, take supply-side structural reform as the main line, take the value of data elements as the guide, focus on consolidating the foundation of industrial development, focus on promoting high-quality data resources, innovative technology and high-efficiency infrastructure, focus on building a stable and efficient industrial chain, focus on improving industrial supply capacity and industry empowerment effect, coordinate development and safety, and cultivate an independent, controllable and open cooperative industrial ecology.

　　According to the Plan, by 2025, the big data industry will maintain rapid growth, the value system will be initially formed, the industrial base will continue to be solid, the industrial chain will be stable and efficient, the industrial ecology will develop healthily, and the modern big data industry system with strong innovation, high added value and independent control will basically take shape. Among them, the estimated scale of the big data industry exceeded 3 trillion yuan, and the compound annual growth rate remained at around 25%.

　　Focusing on releasing the value of data elements, consolidating the foundation of industrial development, building a stable and efficient industrial chain, and building a prosperous and orderly industrial ecology, the Plan puts forward the main tasks of high-quality development of big data industry during the 14 th Five-Year Plan period and deploys key actions.

　　Promote the high-quality development of the big data industry

　　Zhang Li, president of China Electronic and Information Industry Development Research Institute, said that the Plan is based on the realistic foundation of China’s big data industry development, conforms to the law of the times when the industrial economy is striding forward to the digital economy, faces the new direction and new requirements of data factor market cultivation, supports industrial digitalization with digital industrialization, and drives digital industrialization with digital industrialization, which systematically lays out the new stage to promote high-quality industrial development, and is an important guide for the development of China’s big data industry.

　　Zhang Li said that China’s big data industry is welcoming a new round of development opportunities and should vigorously promote the high-quality development of the big data industry.

　　First, strengthen the basic advantage and change the development advantage into the driving force for development. Generally speaking, the advantages of data resources scale, first-Mover advantage in some fields and broad market space are the important support for China’s big data industry to become better, stronger and bigger. We should base ourselves on basic advantages, turn advantages into motivation, fully stimulate the potential of data elements, accelerate the promotion of the big data industry chain to high-end and modernization, continue to deepen the integration of big data and the real economy, and push the development of big data industry to a new level.

　　Second, grasp the core of development and promote the release of the value of data elements.

"Fashion is the most fashionable"　

Salute: as exquisite as Bond? Make costumes into high-end customized brands.

　 　 Kingsman is adapted from a cartoon of the same name in mark millar, which mainly tells the story of Harry Hart, an old agent of Kingsman Secret Service played by colin firth, training Egsey, a little agent played by taron egerton. However, Harry didn’t teach Egsey any real skills. It’s all up to Merlin, the bald instructor played by mark strong. Harry’s task, to be elegant, is to help Egsey, a street thug, become an elegant aristocrat, and to put it bluntly, to teach him how to dress. Therefore, the biggest attraction in the first half of this film is not fists or high-tech weapons, but Harry keeps showing off his suits, shoes, ties, watches and glasses. "Oxford is better than Brock", this clever trick of wearing shoes is an admonition that Harry emphasized to Egsey the most times. I think I was influenced by the spy film ipcress file starring michael caine in 1965.

　 　　Just like Bond, those clothes in Kingsman are well-known. In fact, the Kingsman Secret Service is ostensibly a tailor’s shop, located in the famous Saville Street in London. The shops in this street are all top clothing stores that serve the royal families and nobles of various countries. The prototype of Kingsman storefront is actually a world-famous custom clothing store Huntsman. It is worth mentioning that the film hired Ariane Phillips, who once served "Single Man", as a fashion designer, and cooperated with Mr. Porter, a British men’s fashion e-commerce, to create a customized series of "costume to collection" inspired by movies, which was sold in real life. In addition, the luggage accessories in the film are also of great origin: Turnbull & Asser’s shirt, Drake’s tie, Culture&Gross’s glasses, Swaine Adeney Brigg’s suitcase, Bremont’s watch and George Cleverley’s shoes.

Subversion: gentlemen don’t need muscle blocks!

　 　　Colin firth once played a homosexual in Single Man, and his performance style inspired Matthew Vaughn. We can hardly see any masculine flavor in Harry Hart, but we can experience a different kind of feminine charm. It is not difficult to understand that Matthew Vaughn is deliberately playing against Bourne ultimatum, Mission Impossible and the daniel craig version of 007. "Now spy films are getting more and more boring" is exactly what he thinks of these films. It doesn’t matter to him whether he has a muscle mass or not. The important thing is to wear a suit, which is the kind of elegance and grace shown between gestures. What he wants to pay tribute to is "Underwater City of 007" starring roger moore in 1977. Although this version of Bond has limited physical fitness, it has become the most attractive Bond in Vaughan’s mind because of its ease of weight and humor.

[Carrying equipment can kick and hit]

Salute: Which agent didn’t order high-tech goods?　

　 　　Harry is naturally very proud of his image and clothes, but Egsey, who just came out of the slum, doesn’t buy it. He grew up on the street and likes to wear hoodies or sportswear with hip-hop style. The rebellious teenager was easily fooled by Harry to report to the Secret Service, mainly because Harry’s cool weapons and cool skills shocked him. Like most spy movies, Harry’s high-tech equipment is enough to make him blind. The umbrella he carried when he first met him is a powerful weapon that can be attacked and defended. The tip of the umbrella can fire and the tarpaulin can prevent guns. And almost every accessory on him is a weapon at the same time. There is a sharp knife hidden in the toe of leather shoes, a 500,000 Ford catapult hidden under the dial of the watch, a miniature explosive with the power equivalent to a Grenade in the lighter body, and a toxic pill in the pen tube. Of course, his haute couture suit is also made of special bulletproof material.

Subversion: the moves are fierce and the hair can’t be messy.

　 　 When it comes to fighting, Harry’s action features are bright and neat, which can not only deal a powerful blow to the enemy, but also maintain the elegance of his posture and ensure that his carefully managed hairstyle will not be messed up. It was also in the scene where they first met Egsey that they met a gang of gangsters to provoke them. Harry calmly closed the doors and windows of the hotel, knocked down the gangsters one by one with three strokes and five divisions, and it was like a dance. Colin firth trained for three hours every day for several weeks in order to make a good show. The crew specially invited a number of experts to help, including Jackie Chan’s training team, world Muay Thai champion and Olympic gold medal gymnast. There is also a special forces guy who is responsible for guiding how to use a gun.

　 　　However, if you really meet a strong opponent, it is out of place to consider the image of a gentleman. Terrorists who intend to cleanse mankind are all ruthless dissidents, and agents can only protect themselves if they give them back in their own way. Vaughn deliberately designed the action scene to be fierce and abnormal, which led to the final R rating of the film. Take the opening scene as an example. Agent Lancelot went deep into the tiger’s den to save the hostages and killed all the terrorists. He was so ruthless that people thought he was a villain. Unexpectedly, in the blink of an eye, the goods were split in half by the female killer Jia Zeiler (sofia boutella). Cruel enough! That’s not all. Vaughn later let this sad agent appear again, and his two halves of the body were sewn together by a rope for the villain Valentine (samuel jackson) to "enjoy and ponder". Such humor may be the essence of Vaughan’s aesthetics.

Qingyuan released April sunny and rainy at first sight.

It coincides with the warm spring and flowers.

It’s a good time to step into spring.

Accompanied by frequent turnover of personnel

It is easy to cause diseases such as respiratory tract and intestine.

Qingyuan CDC reminds citizens

When going out to play

Attention should be paid to safety and health first

Be careful in April.

The following seven diseases

hand-foot-and-mouth disease

Hand-foot-mouth disease is mainly caused by enterovirus EV71, Coxsackie virus A16, Coxsackie virus A6 and other enteroviruses. The incubation period is 2-10 days (average 3-5 days). The clinical manifestations are mainly fever and rash or herpes on hands, feet, mouth and buttocks. It spreads through respiratory droplets and faeces, and it is easy to occur in infants under 5 years old. It can occur all year round, and it is spring from April to July.

Guidelines for disease prevention

1. Vaccination with EV71 vaccine can significantly reduce the risk of serious illness and death. In order to play a protective role as early as possible, children are encouraged to complete the whole vaccination before the age of 12 months.

2. Nursery institutions strictly implement the regulations on the management of infectious diseases, implement morning and afternoon inspections, check the causes of absence due to illness, and report the clustered epidemic situation in time.

3. Maintain good hand hygiene, wash your hands before and after meals and after going out and returning.

4. Closed public places and rooms should be ventilated frequently to keep the air circulating. Frequent contact parts, daily necessities and children’s toys are cleaned and disinfected regularly.

whooping cough

Pertussis is a highly contagious acute respiratory infectious disease caused by Bordetella pertussis infection. Since the wide implementation of DTP vaccine immunization, the incidence of this disease has been significantly reduced. However, in recent years, the number of reported cases of pertussis in our city has been on the rise, and some cases have typical paroxysmal and spasmodic cough, with a course of 2-3 months.

Guidelines for disease prevention

1. Vaccination is one of the important methods to prevent pertussis. Children in China should be vaccinated with one dose at the age of 3, 4, 5 months and 18~24 months, and school-age children should be vaccinated with pertussis in time.

2. Try to avoid exposure. If there is a definite infected person at home, the infected person should follow the doctor’s advice and take antibiotics for treatment in time, and pay attention to ventilation at home to reduce close contact with other family members. In particular, infants who have not been vaccinated at home should try to avoid contact with infected people or live in the same room.

3. Strengthening ventilation, washing hands frequently, wearing masks and other preventive measures can effectively prevent diseases transmitted through respiratory tract.

Tick-borne diseases

Acari, generally reddish brown or taupe, long oval, flat back and abdomen, is only the size of a grain of rice before blood sucking, and can expand several times to dozens of times after blood sucking. Ticks mostly live in grassland, farmland, bushes or wooded environment and animal body surface. As the weather warms up, ticks gradually enter an active period. Ticks can spread many diseases after biting people, such as Lyme disease, forest encephalitis, tick-borne hemorrhagic fever, Q fever, relapsing fever, spotted fever, rabbit fever, tick-borne typhus, human granulocytic anaplasmosis, Bartonella infection and so on.

Guidelines for disease prevention

1. Try to avoid sitting and lying for a long time in the main habitats of ticks, such as grasslands and Woods. Do personal protection and wear long-sleeved clothes; Fasten the trouser legs or stuff them into socks and shoes; Don’t wear sandals; Don’t dry clothes on the grass or trees.

2. After you come back from forests, grasslands and other places, you should pay attention to checking clothes and various parts of your body to ensure that there are no ticks attached; If you bring a pet, you should also carefully check the whole body of the pet to prevent ticks from being carried home in the pet hair.

3. After being bitten by ticks, it is generally not recommended to handle it by yourself. It is best to go to the hospital for treatment.

dengue

Dengue fever is an acute mosquito-borne infectious disease caused by dengue virus, which is mainly transmitted by the bite of Aedes albopictus (commonly known as "flower mosquito"). Mainly popular in tropical and subtropical Southeast Asia, Western Pacific, America and Africa. Dengue fever has the characteristics of typical import and suddenness, rapid spread, high incidence, general susceptibility of the population and high mortality of a few severe cases.

With the increase of temperature and rainfall, the density of mosquito vectors increases, which does not rule out the possibility of local infection caused by imported cases in some areas.

Guidelines for disease prevention

1. Wear long-sleeved clothes when going out and try to choose light-colored clothes; Mosquito repellent products such as mosquito repellent can be used in exposed parts of the skin; Install screen doors, screens and other physical protection measures; Avoid staying in the shade, shrubs, grass and other mosquitoes densely.

2. Reduce the breeding of Aedes mosquitoes

Sealing: sealing the water tank, sealing the sewer manhole or installing anti-mosquito devices and sealing useful utensils.

Fill: Fill potholes, waste ponds, ditches, bamboo holes and tree holes.

Dredging: dredge ditches, clean up silt and weeds on the shore.

Row: clear the accumulated water.

Cleaning: remove small containers of garbage, as well as garbage containers such as plastic film bags, discarded bottles and cans.

Novel coronavirus infection

At present, the epidemic situation of novel coronavirus in our city shows a low level of epidemic fluctuation. novel coronavirus has not disappeared, but it is still mutating, and there is still the risk of infection. The general public still needs to do a good job of self-protection.

Guidelines for disease prevention

1. Take the initiative to vaccinate COVID-19 vaccine, wash hands frequently, ventilate more, gather less, maintain good hygiene habits, and wear masks scientifically in crowded places.

2. Enhancing self-immunity and improving self-immunity is an important means to prevent various diseases. Please ask the general public to maintain a healthy lifestyle such as regular work and rest, exercise, drink plenty of water, eat healthily and have a good attitude.

flu

Influenza is an acute respiratory infectious disease caused by influenza virus, which has the characteristics of short incubation period, strong infectivity, rapid spread, etc., mainly manifested as acute onset, severe headache, chills, fever, body aches, fatigue and other symptoms, which are easy to cause outbreaks; High incidence in winter and spring, the whole population is susceptible, pregnant women, infants, the elderly and patients with chronic basic diseases are high-risk groups, and serious complications may occur.

Guidelines for disease prevention

1. Vaccinate against influenza. Vaccinate against influenza is the most effective means to prevent influenza, which can significantly reduce the risk of serious complications of vaccinators. The virus is easy to mutate, so it is recommended to vaccinate once a year, especially for the elderly, children, pregnant women, patients with chronic diseases, caregivers and medical staff.

2. Maintain good personal hygiene, wash your hands frequently and correctly, avoid dirty hands touching your eyes, nose and mouth, cover your nose and mouth when coughing or sneezing, and wash your hands in time.

3. Reduce going to crowded places and wear masks scientifically.

4. Ventilation indoors to keep the air circulating.

5. Have a balanced diet, moderate exercise and adequate rest to avoid excessive fatigue.

chickenpox

Chickenpox is an acute respiratory infectious disease caused by varicella-zoster virus, which occurs frequently in winter and spring. It is characterized by patches, papules, herpes and scabs on the skin and mucosa in batches with mild systemic symptoms. The incubation period is long, generally 14-16 days (ranging from 10-21 days) after exposure to the virus. From 1-2 days before the outbreak of chickenpox infection to the scab of the rash, the infected person is contagious. It is mainly transmitted through respiratory tract and direct contact. April-June and November-January are the high incidence seasons of chickenpox every year.

Children aged 1 -12 are susceptible, and chickenpox is highly contagious. About 90% of susceptible people will get sick after contacting patients, commonly known as "face-to-face transmission". Places where people gather, such as kindergartens and schools, are prone to outbreaks.

Guidelines for disease prevention

1. Vaccination with chickenpox vaccine is the most economical and effective measure. Chickenpox vaccine is suitable for people who are susceptible to chickenpox at the age of 1 and above. Vaccination is recommended for school-age children and people with high exposure.

2. Nursery institutions, schools, etc. strictly implement the regulations on the management of infectious diseases, implement morning and afternoon check-ups, check the causes of absence due to illness, etc. Once suspicious patients are found, they should be disposed of in time, and standardized disinfection should be carried out on the items they have contacted.

3. Maintain good personal hygiene habits. Wash your hands frequently, eat a balanced diet, strengthen physical exercise, and try to avoid contact with patients with acute chickenpox.

4. Strengthen environmental ventilation. Closed public places and rooms should be ventilated frequently to keep indoor air circulation and clean environment.

5. Patients must be treated in isolation at an early stage until all herpes scabs or not less than two weeks after illness.

Shanghai Metro has been able to use the APP directly without a bus card. What’s so special about this APP?

Since January 20, 2018, the whole network of Shanghai Metro has tried to scan the code and pass the gate. It is no longer afraid to take the subway without change and forget to bring the bus card. The scanned QR code is neither Alipay nor WeChat, but an APP called Metro Metropolis.

During the week of operation, people wearing red vests and Yi Labao can already be seen in subway stations, and more and more passengers are using them. For this change that is closely related to travel, curious babies naturally want to know more about it.

Let’s talk about the pioneer of "off-card" pit stop: NFC.

Before Metro was launched, Shanghai Metro was not the only way to get in and out of the station. In addition to bus cards, we can also see many passengers smartly taking out their mobile phones, smart watches and other equipment to enter the station.

I have to mention NFC here. Mobile phones and smart watches that can be swiped into the station are all card simulation modes using NFC technology. The simple understanding is that the device will record the magnetic core information of the bus card when it is tied, and the device is an analog card when it is used.

The efficiency of entering the station is comparable to that of a real bus card, but its limitations are also fatal-only some Android phones are supported. Apple’s mobile phone has actually had NFC function since the iPhone6, but Apple only opened this function for its own Apple Pay, but it also continued its style; Therefore, NFC has lost half of its territory congenitally, and naturally it has been tepid.

"Scan code" is the magic weapon to be compatible with mobile phone operating system.

With the promotion of scanning code payment by Alipay and WeChat, users have become accustomed to scanning code, and the mass base is quite strong. Indeed, the development of mobile payment in China is no worse than anywhere else in the world. The most important thing is that the hardware limitation of code scanning is not as high as NFC, which can basically cover all subway passengers.

Accurate passenger travel data

Scanning the code into the station is undoubtedly a good thing for passengers, and there is another choice, especially for passengers who easily forget their cards and often lose them. However, it seems unreasonable for Shanghai Metro officials to make great efforts to upgrade the gates and bear the extra operation and maintenance costs only from the convenience of passengers-or because Hangzhou next door supports scanning code to buy tickets and scan code to enter the station, and Shanghai, as a first-tier city, has been left behind too much, and it is hard to face.

Of course, there is no way to guess the specific reasons, but accurate passenger travel data is a scarce wealth.

When using the bus card, the subway company also holds the travel data, but all available data are partial, such as which platform has a large passenger flow and which route has a large passenger flow. According to the personal data of passengers, there are actually related records, such as the frequency of this user taking the subway, the route he often takes, and the time of commuting. However, because the bus card is anonymous, it is impossible to attribute these data to a certain user, let alone the user who triggered this part.

When users start to scan the code and enter the station, all this changes, and the data can be accurately corresponding to a passenger; Perhaps this part of the data can’t be used for the time being, but it is a scarce wealth for smart travel and smart city construction in the future.

Scanning code is a good thing, but why should there be a "Metro Metropolis"? Why not use Alipay or WeChat directly? This is also a question of many people. Obviously, using Alipay has a better experience for passengers. In view of the installed capacity of Alipay, there is no need to worry that users need to download an APP again when using it.

Besides Alipay, there are WeChat and UnionPay.

When Shanghai promoted the matter of scanning code and taking the subway, it was impossible not to consider Alipay at all, but if you think about it carefully, there are WeChat and UnionPay. Do you need compatibility? After all, Shanghai is not Hangzhou, so it is impossible to bet on the Alipay family. If you scan the code and take the subway in Alipay now, the current ticketing system and gate equipment are bound to be reformed. When you access WeChat or UnionPay in the future, you will face the possibility of repeated reforms. Why don’t official website Metro make its own Metro Metropolis APP, establish its own platform, and unify the specifications, so that no matter whether it is connected by WeChat or other manufacturers in the future, there is no need to make additional transformation. This is actually a long-term plan.

Who is the subject and who is the entrance of traffic?

Who is the subject. If Shanghai Metro opens the boarding code function on Alipay APP, the answer to this question will be vague, and scanning the code to ride will become a function of Alipay, which will contribute to Alipay’s market share and stability in Shanghai, and the entrance of user traffic will also be concentrated on Alipay APP. Shanghai Metro won’t do this, thus losing its initiative and future bargaining power.

Moreover, the installed capacity of Shanghai Metro’s own official APP has been very small, and it is not suitable for commercial advertisements. You can just take a ride to promote the function of scanning code and increase the download volume of "Metro Metropolis". After traffic, putting some advertisements can also be regarded as a means of profit.

Travel data

If the user completes the whole process of scanning the code on Alipay APP, all the user data will remain in Alipay. The accurate user travel data that the subway official has always wanted, as well as the reach of users in the future, is a fantasy.

Indeed, we found that the scope of cooperation between Metro Metropolis and Alipay and UnionPay is limited to providing users with real-name authentication capabilities and payment capabilities.

For various reasons, Shanghai Metro chose to build its own APP, but their experience and technical strength are far less than those of professional Internet companies in making applications.

Here are a few cases:

"Oh, my God, why do you have to turn on Bluetooth?"

Among them, the most talked about is to turn on Bluetooth. Indeed, when our "Metro Metropolis" APP scans the code, it must turn on Bluetooth. Why? The direct reason is that official website chose the self-built APP, and the fundamental reason is that the QR code can only interact in one direction, and the APP can’t get any information through the QR code. The passenger’s fare calculation is done independently by APP. If APP can’t get the location of the station, it can’t calculate the fare at all.

In order to solve this problem, Shanghai Metro has also spent a lot of effort. Through a series of problems with companies, it has launched the technology of "Double Offline BLE Bluetooth Write-back of QR code", and the story of "Double Offline" is left to the next node, saying that "Bluetooth Write-back" is actually a means for subway gates to inform APP passengers of the information of getting in and out of the station. The general process is as follows:

1. The mobile phone generates a two-dimensional code (including the user’s id, mobile phone Bluetooth address and other related information).
2. The gate reads the QR code information and sends it to the controller.
3. The controller on the gate calls the Bluetooth module of the mobile phone.
4. The mobile phone Bluetooth establishes communication with the gate controller, and writes back relevant information (information of the subway station, arrival time, etc.).
5. The gate is released.

Under normal circumstances, the above interaction process needs to be completed within half a second.

So, you must turn on Bluetooth. Why don’t you turn on Bluetooth when Alipay shows the QR code for payment, because nothing will be written back at all during the payment process. After the merchant scans the code, it has nothing to do with the QR code, and the user Alipay only receives the follow-up notice.

The impact of this technology:

1. The existence of Bluetooth write-back technology also prevents criminals from taking my QR code screenshot to ride.
2. Due to the problem of Bluetooth adaptation, subway officials have listed a list of unsupported mobile phone models. Many mobile phone manufacturers have castrated the Bluetooth function, so this kind of mobile phone is not in the support list.

"We are really thinking about passengers. If you don’t believe me, look at our dual offline technology."

In the real use process, some users will still stand in front of the gate and connect to the internet, then open the APP and bring up the QR code page. In fact, as long as the QR code is loaded, there is no need to connect to the internet for future refreshing. This point also fully considers the user’s usage scenarios. The signal in the subway is always unstable. If users are required to connect to the Internet during the process of opening or refreshing the QR code, it will greatly affect the user experience.

Conflict with NFC

Because the newly modified gate supports bus cards, NFC devices and code scanning devices at the same time, if a smart phone has NFC turned on and Metro Metropolis installed at the same time, it will be difficult to identify the gate, and it is obvious that passengers want to use Metro Metropolis. As a result, NFC may work because of the wrong approach posture, leading to the success of swiping the card. Because of this, the Android version of Metro Metropolis requires passengers to turn off the NFC function during the activation process. But in the long run, when the subsidy for "Metro Metropolis" ends, I think passengers may close the "Metro Metropolis". After all, NFC swipes cards faster and can take public transportation.

"Where did you put our bus passengers?"

From the above introduction, we can feel that Shanghai Metro has completely abandoned the bus card in this mode. There is no need to use the bus card in the whole process, but the good thing is half done. When passengers take the bus, they can’t use the "Metro Metropolis". At this time, they can only take out the bus card honestly, and after swiping the card, they find that the concessions for subway bus transfer are gone. Passengers are definitely unhappy. After all, there are not a few passengers who transfer between subway and bus during commuting. These users are destined not to become deep users of "Metro Metropolis".

I have also experienced the "metro Metropolis" many times recently, but I have never chosen to use it during the morning rush hour, or I quietly turned out my bus card and quickly passed the gate.

Product experience:

1. The stability of the APP: Many people have reported that after the code scanning is successful, the gate will not be released at all.
2. Number of gates: Now it seems that there are two gates at the entrance and exit of each platform to support code scanning. The number is still small. During the peak period, there was a queue in front of the code scanning gate, but the ordinary gate was unimpeded.
3. There is a single type of gate: in addition to ordinary gates, there is also a large baggage gate, and there is no large baggage gate that supports code scanning at present.
4. Efficiency of passing the gate: scanning code is faster than NFC, and faster than swiping the card. If someone opens the APP in front of you in the morning rush hour, it’s not enough to brush it a few times. You must want to kick him to death in your heart, but he is also in a hurry.

Brief analysis of product positioning;

The people who take the subway are roughly divided into permanent residents and tourists.

If permanent residents often take the subway, they will definitely get a bus card, which is faster than you. If the monthly consumption quota reaches a certain limit, there will be a discount, and there will be a discount for transferring to the bus.

Tourists certainly don’t understand and don’t want to understand "metro Metropolis". It seems that a one-day subway ticket is more suitable for them.

At least for now, regardless of existing subsidies. I think the bus card is better than "metro Metropolis", both in terms of convenience and economy.

This analysis has not yet involved the design of other product functions and the interaction with related pages. Wait until the user is stable, and after several iterations, do another analysis.

Recently, a news in the field has aroused widespread concern. It is reported that some owners of Xiaomi models found a new function called "lap time assessment in ranking mode" when receiving the update of Xiaomi HyperOS system. This function claims that if the owner can achieve the officially recommended lap time on the designated track, he can unlock the ranking mode.

This news quickly fermented on the Internet, which triggered heated discussions and doubts among car owners. However, the situation quickly reversed, and many car owners confirmed that Xiaomi had cancelled this OTA update.

In the face of this storm, Xiaomi officially responded quickly. They said that the company has always been committed to establishing good relations with users and attaches great importance to users’ feedback and interests. In the future, before OTA push, we will strengthen communication and forecast with users to ensure the transparency of information and users’ right to know.

According to a car owner of Xiaomi SU7 Ultra, Xiaomi’s sales staff has contacted him actively, apologizing for the incident and offering a car wash machine and points as compensation. The owner said that although the track mode is not used frequently for him personally, he still appreciates Xiaomi’s positive response and compensation measures.

"I think Xiaomi’s handling of this incident is very sincere," the owner said. "They plan to launch a new version of the car machine within 4-6 weeks, and provide 5000 points and car washing machines as compensation for the owners who are locked in power. You can also enjoy the service of free pick-up and delivery of cars to upgrade new cars. "

This incident not only tested Xiaomi’s crisis handling ability in dealing with emergencies, but also highlighted the importance of user feedback to enterprises again. Xiaomi’s quick response and positive compensation measures have undoubtedly alleviated the dissatisfaction of car owners to some extent.

However, different car owners have different views on this incident. Some car owners think that Xiaomi’s compensation measures are sincere enough, while others hope that Xiaomi can pay more attention to the actual needs and experiences of users in future product updates.
