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.

　　CCTV News:The plot is always so similar. When people temporarily forget the barbaric growth, a sensational social news brings the rental platform under the chain home to the public’s attention.

　　On October 16th, a netizen named "My free neighbor is a fugitive" posted in Weibo that on October 13th, there was an incident of chopping people with a knife in a free shared rental house. Afterwards, there was blood all over the floor and walls of the rented house, and the smell of blood lingered, making other tenants unable to live, but they freely failed to give other tenants a reasonable explanation.

　　The authenticity and specific details of the incident have not yet been determined, but from the "deadly formaldehyde room" to the "horror camera", it claims to have the freedom of "artisan spirit" and has fallen into a number of negative public opinion whirlpools in recent months.

　　The tenant hacked people in the room. Manager: "What has affected you?"

　　On October 16, 2018, Weibo netizen "My free neighbor is a fugitive" posted that a fugitive with a criminal record had been living in his free room in Haidian, Beijing for half a year, and he hacked someone with a knife in his shared room last Saturday. After the incident, the room was covered with blood, but freely did not give other users a reasonable explanation.

　　Party Weibo (screenshot)

　　At the same time, there was a video posted on the Internet, in which there was a pool of blood on the floor of the room, bloody footprints spread all over the room, and white chairs and walls were splashed with stars. ……

　　In a recording widely circulated on the Internet, the manager’s complaint about the tenant’s anger seems quite indifferent: "I’ll have someone buy you some incense and make some fragrance in the house." In order to show his "sincerity" in handling this matter, the manager also asked the tenant what flavor of air freshener he liked.

　　In the subsequent dispute, the manager confidently asked the tenant, "What happened to you (in the house)?"

　　The authenticity of the recording can not be tested for the time being, and there is no public denial in terms of freedom.

　　After the public opinion fermented, the free customer service responded in Weibo that the matter was an emotional dispute between Ms. Zhang, a free tenant, and two men. The injured person was her ex-boyfriend and the injured person was her current boyfriend. Ms. Zhang is a free tenant, and neither the injured person nor the victim is a free tenant. He also said: the poster made a rumor that Ms. Zhang, the tenant, was a fugitive, which seriously infringed on the reputation of the company and Ms. Zhang, and freely reserved the right to pursue the legal responsibility of the rumor maker.

　　The reporter of "Legal Evening News" contacted the tenant. According to him, after the incident, due to the heavy smell of blood in the room, the poster contacted the free staff, hoping to change the similar room in the same area freely, but was rejected. If you want to "dry the blood", the tenant can go back to live that night. After the tenant refused, he freely said that he could stay in a hotel below 300 yuan for one day, and the company would reimburse him, and then he would live in the rented house after the matter was settled. "　

　　According to the owner, the tenant was taken to see the house after the incident, and only the poster failed to change the rent successfully, or the price was slightly different from the incident room because of the size and location of the room.　

　　At present, the incident continues to ferment, and there is no updated explanation from the free side, and no other actions have been seen in public relations.

　　"Privacy and life are the same."

　　Free official website (screenshot)

　　On the official website, a rental platform owned by Chain Home, there are a row of rooms to be rented: Mo Landi-colored walls and bedding, simple and neat iron or wooden furniture, and the sun shines through bright windows. This is a tenant’s ideal good residence, which meets the various needs of young people for a warm, decent, safe and orderly life.

　　At the beginning of its birth in 2011, it was free to provide an ideal home for young people struggling in big cities, and chain home executives also advertised the "ingenuity" of the company many times in interviews.

　　However, the word "ingenuity" was particularly ironic after a self-media article titled "Alibaba P7 employee died of leukemia and rented a free formaldehyde room before his death" was screened in September this year.

　　Ali, a 37-year-old employee, died of leukemia in less than two months after staying in a free room with excessive formaldehyde. Since then, the Beijing News reporter visited a number of freely rented houses and found that some houses suspected that formaldehyde exceeded the standard. According to the national standard, the indoor formaldehyde standard is 0.1 mg/m3, but the reporter found that the data was as high as 1.018 mg/m3 in a living room, which exceeded the standard by 10 times. Excessive formaldehyde has caused many tenants to have headaches, dry and itchy throats.

　　This is not the first time that formaldehyde in the room has exceeded the standard. However, in the first-tier cities where land is scarce and it is not easy to live in a big place, mature and high-quality housing is quite scarce, and the urgent need for a place to live makes people reduce their consideration of living safety to the second place. It’s just that it’s hard for a rental platform that prides itself on "artisan spirit" to make use of consumers’ eagerness to fish in troubled waters, lower the requirements for housing quality and earn "ambiguous money".

　　Some netizens said that they are a "green radish" who lives in a free room and sucks formaldehyde for free. Behind this black humor is the helplessness and protest of tenants.

　　In the face of surging public opinion, I freely apologized first, then promised that the newly collected houses would be vacant for 30 days, and then rented out after passing the formaldehyde test. In addition, I also took remedial measures such as returning the rent and measuring formaldehyde for free, which was an account for the tenants.

　　For an enterprise that has exposed multiple problems in risk control, management and compliance, "calm" has become a luxury.

　　The "pinhole camera incident" will be freely pushed to the forefront of public opinion.

　　The camera found by the party Chen Cheng (pseudonym) at home (Source: Network)

　　The client Chen Cheng (pseudonym) said that on the evening of September 11th, he found a "strange little hole" on the bedside socket, and it was suspected that a pinhole camera was installed. After reporting the case, it was confirmed by the police that there was a sneak shot device hidden behind the socket.

　　The tenant said that things have been reflected for more than a month, and the company has never given a solution. During this period, only one director stated that this matter has nothing to do with the company.

　　On October 14, the incident was exposed from the media and quickly fermented. On the 15 th, I finally made a public response freely: I have cooperated with the public security organs to file a case for investigation. It is natural to emphasize that the company has strict process inspection and system control on the decoration and configuration of newly-received and second-rented houses. After the incident, the safety management center of the company will further sort out and investigate the hidden dangers with the quality management, decoration and configuration and lease management departments.

　　On the morning of 16th, I had an interview with the tenant freely. However, at the end of the interview, the tenant said that he was free to propose another room change for himself, but he would not change rooms until the dust settled.

　　One after another, the lawsuits that have not yet "settled the dust" consume the reputation that you have been proud of for many years. Some netizens commented with intense emotions: "Living freely, privacy and life are the same." Search Weibo, and you can even see users with the nickname "Free to go out of business today".

　　Does an apology work or not?

　　In 2018, Didi apologized to the public twice for the "flight attendant murder case" and "Wenzhou girl murder case", each time being more sincere. In the open letter, Cheng Wei and Liu Qing reflected on their mistakes to the depths of their souls, saying that "the competitive heart overshadowed the initial heart" and "the lack of awe". In the eyes of the public, this did not save Didi’s reputation, more like "crocodile tears."

　　There are self-media predictions, and a free apology should not be far away.

　　As a traditional format upgraded by the Internet, it stands out in the rental market where "black intermediaries" are everywhere, focusing on better housing, stricter management, more transparent procedures and more humanized services. It is precisely because of this that young people are willing to pay hundreds or even thousands of dollars to choose it every month.

　　In recent years, snowballs have been getting bigger and bigger. In June of this year, it freely announced its achievements, saying that it has settled in nine cities across the country and managed 600,000 houses, claiming to be "the largest professional leasing institution in China".

　　However, there are frequent problems in management. In addition to several vicious incidents sorted out in the article, in the winter of 2017, in the special action of large-scale investigation, large-scale clean-up and large-scale rectification of potential safety hazards in Beijing, the partition room that was free from compliance was demolished, resulting in many households having nowhere to go; Social news about disputes over housekeeping, cleaning and household finance is also frequently seen in newspapers.

　　Looking at the free negative news, unlike Didi, it is not the business logic that has been criticized, but the procrastination and casual attitude after the incident, which is contrary to the entrepreneurial spirit it has always advocated. From indifference to formaldehyde housekeepers, to inaction in "camera incident" and "hacking incident" … … Free "arrogance" keeps consumers’ "prejudice" escalating.

　　So, here’s the problem. Where does the "arrogance" come from?

　　Internet companies provide services with matching information as the core to meet people’s needs of "food, clothing, housing and transportation". At the same time, there is also a huge "information gap" between consumers and enterprises. If you want to buy the convenience and comfort brought by this information, you must endure the "store bullying" of Internet companies.

　　Therefore, there are complaints on the Internet. In real life, on the flashing screen in the hands of "commuters", it is still dripping to match suitable vehicles for them; Young people who have just graduated still have to go back to the rented "free room" to settle down for a day’s fatigue.

　　This is a dilemma. As netizens said, "Didi is better than a black car" and "Free is better than ‘ Black intermediary ’ Good. "

　　In this dilemma, freely, Didi began to "pretend to sleep". They seem to forget that behind the massive information they have obtained are ordinary users; The market on which the pursuit of profits depends is also made up of ordinary users. They seem to forget that technology and algorithms can certainly create a more convenient life, but if consumers are regarded as dirt, it will only be a matter of time before word of mouth collapses and reputation goes bankrupt.

　　Marx once said: "Capital comes into the world from head to toe, and every pore is dripping with blood and dirty things". To clean the pores for the capitalists, it is far from enough to rely solely on their consciousness and conscience. In the past six months, Internet companies have intensified their rectification efforts, Didi has been interviewed and freely interviewed, and the "teeth" of supervision have become sharper and sharper.

　　Life is more than a room. The beautiful declaration of freedom is still hanging in official website, but they have no further explanation or public relations behavior in view of the fog of the "chopping people" incident.

　　Will the future be good?

　　"I don’t know in the future, 2013 is better. At that time, their services were not bad. " In an interview with a reporter, someone said so.

　　That year, Tencent invested 15 million yuan to take a taxi, and the iphone version of the APP was officially launched. That year, we came into contact with a brand-new concept — — "The Internet creates a better life for people".

CCTV News:Five departments, including the Ministry of Industry and Information Technology, issued an announcement on matters related to the implementation of the national six emission standards for automobiles.

In order to implement the Emission Limits and Measurement Methods of Light Vehicle Pollutants (China Phase VI) (GB 18352.6— 2016) and "Pollutant Emission Limits and Measurement Methods for Heavy Diesel Vehicles (China Phase VI)" (GB 17691— In 2018), the relevant policies to help enterprises bail out, stabilize and expand automobile consumption are implemented. The relevant matters concerning the nationwide full implementation of the National Sixth Emission Standard 6b for light vehicles and the National Sixth Emission Standard 6b for heavy diesel vehicles (hereinafter referred to as the National Sixth Emission Standard 6b) are announced as follows:

1. From July 1, 2023, the national sixth emission standard 6b stage will be fully implemented, and the production, import and sale of automobiles that do not meet the national sixth emission standard 6b stage will be prohibited. The production date is based on the vehicle manufacturing date of the motor vehicle certificate, and the electronic information of the certificate should be uploaded before 0: 00 on July 1, 2023; The date of import is based on the date of arrival of the goods import certificate; The date of sale shall be subject to the date of motor vehicle sales invoice.

Two, for some of the actual driving pollutant emission tests (that is, RDE test) report results as "monitoring only" and other light vehicles, give a half-year sales transition period, allowing sales until December 31, 2023.

Three, automobile production and import enterprises, as the main body responsible for the consistency management of environmental protection production, should disclose the vehicle emission inspection information and pollution control technical information before the vehicle leaves the factory or enters the country according to the relevant provisions of the People’s Republic of China (PRC) Air Pollution Prevention Law, so as to ensure that the actually produced and imported vehicles meet the requirements. Relevant certification bodies shall issue compulsory product certification certificates according to the national six emission standards 6b stage.

　　Recently, a master’s thesis entitled "Sociological Research on Fart" was circulated on the Internet, causing controversy. Some netizens are "sarcastic": Cold Window has studied hard for so many years, and it is really a "fart". Some netizens commented after reading that things that seem meaningless and are sneered at are "serious things to dig into."

　　The Paper noted that the paper was written in 2007 by Gao Jianwei, an in-service master of sociology at Huazhong Normal University. At that time, Gao Jianwei not only passed the master’s thesis defense with this paper, but also was rated as "excellent".

　　As early as 2015, the paper had aroused public concern. Li Yaxiong, a tutor of Gao Jianwei and a professor at Huazhong Normal University, said in an interview with the media at that time, "There are actually many aspects in life that are worth exploring, and there is no need to always repeat some meaningless topics. Some topics that look different or niche are often more worthy of consideration and there will be more interesting discoveries."

　　In this regard, Zheng Zuoyu, a professor at the School of Sociology of Huazhong University of Science and Technology, believes that whether the paper can be written well depends on whether the attitude is correct. In his view, even if the topic is high, but the attitude is not good, "no use"; On the contrary, if the academic attitude is correct, the topic "No matter how bizarre it is" can also be described as a classic.

　　The thesis was praised by the tutor.

　　"I am often mentioned by people around me such a question: How did you do such a topic?" Gao Jianwei explained at the beginning of his thesis "Sociological Research on Fart" that he chose this topic because he accidentally saw two stories about fart on the Internet. In both stories, the protagonist changed his life track because of a fart, which triggered Gao Jianwei’s thinking.

　　Gao Jianwei believes that "fart" is not only a physiological phenomenon, but also a social phenomenon, which has various correspondences with social relations. Through the study of a large number of historical materials, he pointed out that fart exists as a social taboo in both western culture and eastern culture. This taboo not only spreads in all aspects of our daily life, but also widely exists in the superstructure fields such as education, manners and customs, habits, morality and even law.

　　Gao Jianwei deeply analyzed how fart behavior and phenomenon changed from a physiological behavior to a social taboo from the perspective of social genetics, and revealed the complex mechanism of this operation process. In the process of social development, fart has evolved from indiscriminate human behavior to behavior that occurs more frequently among some social members, and then to negative behavior in moral evaluation, and finally evolved into a form of social taboo.

　　The paper mentions that in the early stage of human beings, division of labor and class have not yet appeared, and fart behavior is primitive human beings — — That is, the most frequent and common physiological phenomenon of our ancestors. With the development of productive forces, social relations have changed, and the diet types and habits of the rich have changed, and they no longer fart frequently. At this point, the human fart experience has completed the first historic change, that is, from a common physiological phenomenon of human beings to a behavior that occurs more frequently and more commonly among some members of society (more poor people).

　　Through this transformation, fart behavior has gained some social significance, reflecting the fact that the upper and lower classes coexist and oppose each other. In order to maintain its dominant position, the upper class not only establishes an absolute control position in the political, economic and cultural fields, but also strives to "shape" the social state that adapts to its dominant position. Distinguish the upper and lower classes by etiquette, self-cultivation and taste. The upper class is often considered polite, while the members of the lower class are ordinary, vulgar and even despicable. In this context, farting is labeled as a negative moral label. Under the power of discipline, "fart" has changed from a negative social behavior defined by the upper class to a social taboo, and has been recognized and obeyed by all members of society.

　　He believes that this genetic process comes from the strange characteristics of power operation, namely, duality, dependence and publicity. Then it discusses the fart behavior and phenomenon of "no taboo", and thinks that this phenomenon essentially reflects the taboo existing form of fart behavior and phenomenon, and is related to the strange characteristics of power operation.

　　The Paper noted that this is not the first time that this paper has been concerned by netizens. In 2015, Beijing Evening News reported on this matter. Li Yaxiong, Gao Jianwei’s tutor and professor of Huazhong Normal University, was quite appreciative of the paper when interviewed.

　　According to his memory, when the paper was opened, the teachers all laughed at the first sight of the topic, but after the "laugh", everyone quickly discussed its academic value from a professional point of view, not simply talking about the matter, but using sociological theory for analysis. Li Yaxiong told the Beijing Evening News reporter at that time that Gao Jianwei’s research found a new way. In the case of repeated research, it was "precious" and teachers generally supported it.

　　"The defense effect is also very good, and it has also been rated as excellent. He (Gao Jianwei) has a good writing style and clear thinking. " Li Yaxiong said that because it is not convenient to do actual investigation, Gao Jianwei presented the genesis of fart, its vertical development in different times and the social meaning behind it through literature analysis and quotations. "I welcome this topic that comes from life and has humanistic care."

　　In this regard, The Paper recently contacted Professor Li Yaxiong several times for an interview, but the other party declined on the grounds of being away on business.

　　College teachers: With a correct attitude, no matter how strange the topic is, it can become a classic.

　　In fact, in recent years, many papers have attracted public attention because of their unique topics. Previously, papers such as "The Utopian Cat: The Identity and Fantasy of Cats Fans" and "The Influence of Illicium verum on the Volatile Flavor of Braised Chicken and Its Mechanism" have caused heated discussions.

　　"This is a question of diversification of topics, which I think is a good thing." Rui Liu, tutor of master students in Huazhong University of Science and Technology, believes that the development of disciplines is characterized by "specialization" and "cross-integration", and "many problems that we didn’t think could be studied before have emerged now". "Personally, I think it is necessary to study such different problems, which can cover many blind spots of previous knowledge and inspire the society." Rui Liu said in an interview with The Paper recently.

　　In this regard, Zhou Tingting, an associate professor at the School of Journalism, Huazhong University of Science and Technology, believes that college students are active in thinking or familiar with new media, so they can really pay attention to some new phenomena. "Many phenomena can be used as the research topics of our thesis, but we should find an in-depth observation angle based on the discipline, not just describe ‘ Phenomenon ’ It is meaningless to do a simple analysis. " Zhou Tingting said.

　　Tan Songhua, a member of the National Education Advisory Committee, said that he had not read the above papers and could not comment on them. "How to write a graduation thesis, it is difficult to have a unified statement. Students with different majors, hobbies and energies have different factors to consider when choosing a topic. " Tan Songhua said that as far as he guides graduate students, the practical significance is more important when choosing the topic of the thesis, for example, it can promote the development, reform and social progress of the country.

　　For more and more "unique topics", Zheng Zuoyu, a professor at the School of Sociology of Huazhong University of Science and Technology, said that "there is nothing wrong with it". "Academic research should have cared about your life and the society you live in. Now that the era in which students live is full of these phenomena, it is natural to study these phenomena. " According to Zheng Zuoyu, the question is not whether the research topic is "innovative" or "serious", but whether the research attitude is correct.

　　Zheng Zuoyu said that individual students "lead a muddled life" and "choose the most mindless topic" when writing their papers. "Such a topic, even if it sounds tall, is actually vague." Zheng Zuoyu said that attitude is more important for writing papers.

　　"When I take part in the insurance research interview, I will ask students what fields they are interested in and have studied." Zheng Zuoyu found that most students from rural areas would say "I want to do rural research", or most female students would say "I want to do gender research". "But not many of these students have really studied the relevant knowledge. They just think that because of their identity, they can make some sense at worst. " Zheng Zuoyu believes that in this case, even if the topic is tall, the attitude is not correct, and it is "no use"; On the contrary, if the academic attitude is correct, the topic "No matter how bizarre it is" can also be described as a classic.

　　What do students think about the topic of the thesis? Li Yong (pseudonym), a graduate student in a university in Hunan, told The Paper that according to his observation, the source of the topic mainly has three parts, one is the combination of previous practical activities, the other is the combination of interests, and the third is from the tutor. "I prefer topics that I am interested in, and at the same time consider the significance of research, so I am motivated to write." Li Yong believes that interest is a good entry point. "When the school informs you to write a paper, you often feel confused and then choose a familiar field." (The Paper reporter He Liquan intern Hu Tianyi)

Have not had sex all the time, can you not do gynecological examination?

First of all, answer the first question: even if you have never had sex, you need to have a gynecological examination.

Of course, here we should distinguish between broad and narrow gynecological examinations. When it comes to gynecological examination, many fairies first associate it with gynecological examination.

It requires women to lie on a special gynecological examination bed, and doctors can open the yin channel through a speculum (duck-billed forceps) to check the yin channel and the cervix, and if necessary, take samples and check the secretion of the yin channel and the exfoliated cells of the cervix, and then know whether there is any abnormality in the uterus and bilateral ovarian fallopian tubes through Shuang Hezhen or triple diagnosis.

The gynecological examination that our doctors usually say includes a series of laboratory tests such as ultrasound and tumor markers, in addition to physical examination.

For female friends who have never had sex, gynecological examination is definitely not suitable, but this does not mean that we don’t need gynecological examination.

We should not actively ignore or passively refuse gynecological examination because we have never had sex.

Yaota met many female patients who had never had sexual life in clinical work. It was precisely because of the wrong idea that there would be no gynecological diseases without sexual life that the best treatment opportunity for the disease was delayed. Among them, there were many cases of malignant tumors, which can be said to be a lesson of blood.

What makes me feel most sorry is a patient not long ago. She never had sex, so she never had a gynecological examination. She had a gynecological B-ultrasound by chance and found a tumor in her uterus. She sought some Chinese medicine treatment by mistake, but it didn’t work. One day she came to our hospital because of acute abdominal pain.

We thought it was just a simple fibroid degeneration, but after the operation, we realized that the condition was far more serious than we thought. The final postoperative pathology was uterine sarcoma, a highly malignant uterine tumor.

After surviving the postoperative rehabilitation period and unusually uncomfortable chemotherapy, I thought everything was going well. However, less than a month after the end of chemotherapy, the tumor recurred and metastasized to the intestine, and she underwent laparotomy again.

The last time I contacted her, she told me, Yaota, I won’t go to your hospital. The tumor has metastasized to the lungs. I’ll go to another hospital. Later, I didn’t see her update her circle of friends. I don’t know how she is now, but I can still remember her strong smile.

Forgive the demon tower. I’m old, and I feel it. It’s a bit far.

What tests should I do if I have no sex life?

Then answer the second question: even if we have never had sex, we can still do gynecological B-ultrasound (transabdominal or anal ultrasound); You can also check yin secretion, tumor markers and hormone levels. And from the point of view of gynecological physical examination, although we can’t do Shuang Hezhen, we can learn about pelvic cavity through anal examination when necessary.

Gynecological B-ultrasound: It can help us to know the thickness of endometrium, whether there is abnormal echo in uterine cavity (such as endometrial polyp and submucosal myoma), whether there is abnormal echo in myometrium (such as hysteromyoma and adenomyosis) and whether there is abnormal echo in ovarian fallopian tube (such as ovarian tumor and hydrosalpinx);

Yin secretion: it is not that there will be no yin inflammation without sexual life! Doctors can use a cotton swab to get yin secretion for laboratory examination without opening the yin channel with a speculum.

Tumor marker: This test is more routine and simple, that is, blood drawing. Among many tumor markers, CA125, which is closely related to female diseases, is the most common and you know the most. Generally speaking, CA125 will be elevated in many cases, such as before and after menstruation, endometriosis, adenomyosis, pelvic inflammatory disease and ovarian malignant tumor.

Hormone level: including six items of sex hormones, AMH and other tests, we often need to use the results of six items of sex hormones to help doctors judge the condition when diagnosing and treating female endocrine diseases such as abnormal uterine bleeding and polycystic ovary. AMH can help us understand the reserve function of female ovaries and better guide pregnancy preparation. These are also blood tests.

What will happen if I accidentally do the yin examination?

The third question: What will happen if you accidentally do the yin examination?

Before answering this question, first of all, we need to be clear. First, we can’t choose not to check out because of fear or concern. Second, when we ask the doctor, we should clearly tell the doctor that I have never had sex before, so as to avoid the possibility of accidentally doing yin examination to a great extent.

Through the description of gynecological physical examination in Yaota, I believe you may have guessed that the following may happen to women who have no sexual life after yin examination.

ache

Yin Dao flap (common name hymen) is a mucous membrane with certain elasticity. With the invasion of speculum, yin Dao flap has not broken yet, but it will induce vulvar pain due to expansion. At this time, something must be done to stop it.

Rupture and bleeding of yin valve

Some female friends have high elasticity of the yin valve, and there may be no obvious pain in the process of entering the speculum, but with the opening of the upper and lower leaves of the speculum, the yin valve will basically rupture or even bleed during this process.

At this time, it is necessary to compress the wound to stop bleeding. Generally, a sterile cotton ball will be selected, and it will be removed after 5 to 10 minutes of compression to observe the bleeding of the wound.

Because the yin flap is thin, there are often some capillaries distributed here, which can basically stop bleeding through compression. However, if it happens to damage a relatively large blood vessel, it may be necessary to stop bleeding through suture if necessary, but this situation is very rare.

infect

If this happens unfortunately, you must pay attention to the cleanliness of the vulva after the bleeding stops, so as to avoid infection of the wound. Of course, this kind of situation is also very rare, because this kind of wound of yin mucosa usually heals very quickly.

Yao ta Xiao tips

If the doctor gives you a gynecological B-ultrasound checklist, you must see clearly whether it is through the yin channel, abdomen or anus before paying the fee. If it is through the yin channel, or if you feel that you can’t accept the transanal B-ultrasound examination, you must find a doctor to change the checklist.

Original title: "It is strongly recommended that all women must do these four tests during physical examination (whether they have sex or not)"

　　　　First of all, understand the prices of the next three mobile phones: Youth Edition.　3GB+32GB version costs 1199 yuan, and 4G+32GB version costs 1499 yuan.The 4G+64GB version is 1799 yuan.;　The 2 4GB+32GB version is priced at 1799 yuan, and the 4GB+64GB version is priced at 1999 yuan.The 6G+64GB version is 2299 yuan.; Charm blue Note 6　　3GB+16GB version costs 899 yuan, 3G+32GB version costs 999 yuan, and 4G+32GB version costs 1299 yuan.The 4G+62GB version is 1499 yuan.

　　　　This time, I will make a comprehensive comparison of the appearance, system, photography, performance and battery life of these three flagship machine models, and finally give my own opinions for your reference. Let’s start with the appearance of these three mobile phones.

Appearance: three "idols" with close prices and two full-screen models.

　　　　From the appearance point of view, the three models have obvious differences: small size, plus a full screen up to 75.88% of the screen ratio, even a girl with small hands can feel the thrill brought by the big screen; As Lao Luo said, it is a "sharp foreign body", and the design of double-sided glass body with gold thread around it looks very unique.

　　　　It is very mainstream. Because it came out earlier, it failed to catch up with the comprehensive screen design. It is more simple and generous. Of course, 71.73% of the screen is not inferior to the comprehensive screen mobile phone in terms of visual experience.

　　　　On the front of the mobile phone, the three mobile phones are slightly different. Thanks to the 12-layer optical processing mirror upgraded to version 2.0, the touch feel of the youth version is better. The shallow design of the receiver can effectively prevent dust accumulation, which is very intimate;　2 With the minimalist hidden earpiece design, the front is as smooth and bright as a mirror, without any sag or bulge. The front camera is not placed on the left or right, but innovatively set in the middle, which satisfies Virgo’s "mind" for many years; Breathing light, which is equipped with a response system above Charm Blue Note 6, is unique, and the metal edges around the Home button shine under the illumination of lights.

　　　　On the back of the fuselage, the three mobile phones also have different characteristics, and whoever looks better varies from person to person: Glory 9 Youth Edition doesn’t have much innovation, but more is improvement. Its back of the fuselage is very simple, and the dual camera holder is slightly raised. Thanks to the 12-layer nano-scale process, the overall mirror effect is more beautiful than most mobile phones with double-sided glass body, and the hand feel is also very good after one day’s use.

　　　　The back of Nut Pro 2 inherits the "special" logo design of the previous generation, the circular groove template, and the frosting treatment of the "T" letter, so that you can’t help but touch the center circle when holding the mobile phone, because it is made of glass, so you don’t have to worry about touching off the paint. The double cameras that look like a single shot are an innovative move of hammer technology. The 12 million cameras with a large aperture and the 5 million sub-cameras that have been flattened, and the LED fill light with the same aperture next to them, are very novel. Hammer is a company that likes to dig into details. It is precisely this that the nut series products have turned over so successfully.

　　　　From the back, almost all of them are the shadows of their predecessors: the symmetrical design on the top and the flowing flash on the top. However, Meizu’s industrial design rarely disappoints us. The flash integrated into the antenna belt, the double camera arranged up and down, and the front fingerprint recognition all look very comfortable.

　　　　The design of three mobile phones at the bottom of the front of the fuselage has its own advantages: the bottom of Glory 9 Youth Edition is printed with the exclusive "honor”logo of glory, and the recognition of the mobile phone is very strong. You can recognize that it is HONOR from a distance or a close look at others; Nut Pro 2′ s "flat and narrow" function bar is unique, and the vibration given by pressing is relatively light and cool, which is very good; There is not much to say on the front of Charm Blue Note 6, which is not far from the mainstream 16:9 mobile phone. The design of pressing the mBack Home button with integrated fingerprint is more comfortable and resilient.

　　　　At the bottom of the mobile phone, Glory 9 Youth Edition and Charm Blue Note 6 all adopt the current popular design. From left to right, there are 3.5mm headphone jack, Micro-USB and a row of speakers. The nut Pro 2 is more simple, with the 3.5mm headphone jack removed, the Type-C jack in the middle, symmetrical speaker holes on both sides, and no screw at the bottom. This design adds points to the look and feel of the nut Pro 2.

　　　　Side contrast is also the mainstream of Glory 9 Youth Edition and Charm Blue Note 6. The left SIM card slot design, the right power button and volume button design, while the nut Pro 2 looks a bit "bright", and there is a flash capsule shortcut button on the left. The surrounding Phnom Penh also makes it have enough "hammer features".

　　　　Summarize the design of three mobile phones: Glory 9 Youth Edition double-sided glass design, which belongs to the rounded appearance of the fuselage. Thanks to the comprehensive screen design, it has a greater visual experience in a smaller body size and is suitable for students.

　　　　Nut Pro 2 is different (of course, different doesn’t mean ugly), which keeps the sharp fuselage of the previous generation as a whole, further enhances the smoothness around it, and looks more mature than the previous generation. The four minimalist designs of hidden earpiece, hidden distance+light sensor, hidden double camera and hidden fingerprint recognition are also the unique competitiveness of nut Pro 2 in terms of face value.

　　　　Although Charm Blue Note 6 doesn’t have many features, it feels more neat and square. Although the CNC high-gloss trimming in the last two weeks is somewhat cut, it is relatively firm to hold, and there is no need to cover the silicone case and worry about slipping.

　　　　Of course, turnips and vegetables have their own tastes. I can’t instill my own preferences in the comparison of appearance. I have to say that this one is better than that one, and it is more the user’s own repeated research and pondering to choose his favorite one.

System: Flyme6/EMUI8.0"silky" fluency　　　Smartisan OS 4.1 is innovative.

　　　　There are two major developments in EMUI this year. One is to upgrade EMUI5.0 to EMUI5.1, and the other is to launch EMUI8.0. According to the inertia of glory, the thousand yuan machine is usually equipped with EMUI5.1 system, but it is really gratifying to have EMUI8.0 with conscience. The EMUI8.0 system is greatly optimized and intelligent, which enhances the intelligent experience of users.

　　　　This model supports enhanced F2FS file system, efficiently optimizes system cache and defragmentation, and creatively optimizes the problem of long-term usage of Android system. Built-in Kirin i5 coprocessor in the fuselage can count steps at any time with low power consumption, and the step counting data can be automatically synchronized to the movement. It can be said that it is very intelligent.

　　　　Equipped with Smartisan OS 4.1 with deep customization, the small improvement of many functions is the highlight of the system.

　　　　Smartisan　OS　4.1Including the 1.0 official version of the flash capsule (adding reminders and accessories. One-on-one sharing and other small functions), Big Bang version 2.2 (voice conversion text is added in the editing mode to help users modify the semantic substitution function of typos), and the intelligent sorting function of dragging and dropping the sharing sidebar is added. In appearance, Hammer Technology likes to dig into details, but in the system experience, the practical small function of "grounding gas" still fails to disappoint consumers.

　　　　2017 is not only the first year of full-screen explosion, but also the year of system leap and upgrade. Facing the system optimization of various manufacturers, it is not inferior. This machine is based on the deeply optimized Flyme 6 operating system of Android 7.1.2. Flyme 6 has been comprehensively improved in three aspects: design, function and artificial intelligence. This system further adjusts the main color and UI layout, which is uniform, textured, well-defined and readable, making it dominant in color, andFlyme 6 is the second biggest killer for Charm Blue Note 6 to conquer users after taking photos.

　　　　Flyme　6Based on the user’s scenes, habits, information and content to be sent out, geographical location and other information, Charm Blue R&D team developed a series of analysis engines for the original intelligent thinking engine "One Mind", so that it can learn the user’s operating habits independently, and provide efficient solutions according to the use of scene intelligence to create a smarter and more casual system.

　　　　From the system comparison, the three mobile phones all have their own different characteristics. The youth version tends to be "smart", 2 tends to be "innovative", and Charm Blue Note 6 tends to be "practical". How to choose it depends on the user’s wishes.

Shed pat: the data is a piece of stone, but three pieces are all "gold"　

　　　　Shed shooting is a standard for us to judge taking photos, and it is also a link for evaluating mobile phones. The essence of photos can not be separated from several dimensions, such as resolution, color orientation, white balance, tolerance, etc. Therefore, our evaluation standard starts the standard photo environment, builds a datable photo template, and quantifies the experimental data with the help of Imatest, and finally obtains authentic evaluation results.

　　　　Resolution refers to the ability to distinguish the details of the original object. The better the resolution, the better the control of the details, and the more natural the transition of the details of the picture. There are many ways to test the resolution. Here we choose the linear test method, which has the advantage of being very intuitive and can be observed with the naked eye. We intercept part of the test sample as the test area to test the resolution of three mobile phones.

　　　　It is not difficult to see that the resolution of the camera is slightly excellent, and more details are reserved. All three models are dual-camera phones, and the resolution results are close to the standard of flagship models.

　　　　Shoot the 24 Color Check test card in the tent shooting environment, and get the color deviation δ E and white HSV saturation through Imatest analysis. Color difference ΔE is actually the difference between the measured color and the real color. The bigger the difference, the more serious the color cast.

　　　　It can be seen that the color difference δ E of is the smallest, which is 8.71, followed by. The size of the color difference also shows the different manifestations of the imaging style of the mobile phone from the side. The youth version strives to be true but slightly bleak.Charm blue Note 6The colors presented are brighter and more pleasing to the eye.

　　　　White balance is an index to describe the white accuracy after the mixture of red, green and blue primary colors is generated. Many people will encounter such problems when shooting with digital video cameras: the images taken in the fluorescent lamp room will appear green, the scenery taken under the indoor tungsten filament light will be yellow, and the photos taken in the sunlight shadow will be inexplicably blue, and the reason lies in the "white balance". The value of white balance is as small as possible, so the values of Glory 9 Youth Edition and 2 are the same, slightly better, and Charm Blue Note 6 is also better.

　　　　Dynamic range refers to the brightness range of the subject-the brightness span from the darkest point to the brightest point in the subject. Shoot the gray-scale color card in the tent shooting environment, and calculate and analyze the dynamic range level of the camera through Imatest. The bigger the value here, the better, so we can see that the dynamic range of Glory 9 Youth Edition and Charm Blue Note 6 is better, with the total number reaching 6.31 and the score of Nut Pro 2 reaching 6.03, which is also excellent. All three phones can retain more details from the brightest to the darkest.

　　　　The above data may not intuitively show who is better at taking pictures. After all, according to our Zhongguancun Online standard, they have got a lot of full marks in various tests. Now, mobile phone photography may need to consider whether the film is more pleasing to consumers’ eyes. Then, let’s look at a set of real-life proofs.

Proof: the strength of dual camera is not simple. All three images are satisfactory.

　　　　The front and rear are equipped with 13 million+2 million dual cameras, and the front camera has a maximum aperture of f/2.0. With more layered hardware-level blur, AI private customized beauty, and gesture photography, you can peel off the most dynamic and beautiful pictures at any time.

　　　　The rear main camera has 12 million+5 million pixels, and adopts IMX386 sensor, which has a pixel size of 1.25 μm and a large aperture of f/1.8. This sensor is quite famous and has been used in many flagship machines.

　　　　It is also a "famous camera". Its camera with 12 million+5 million dual cameras, f/1.9 aperture and PDAF phase focusing has a good imaging effect. Let’s enjoy the proofs together:

caption

　　　　Generally speaking, the three dual-camera performances are of the same price and higher level. First, the youth version has more accurate resolution and more realistic colors, which is closer to the scenery seen by human eyes. The color of 2 is more beautiful, and the perception is more pleasing to the eye, and when shooting at night, both the control of background purity and the noise treatment of lighting show the flagship charm; The overall shooting performance of Charm Blue Note 6 is not weak. Whether it is day or night, the details are handled in place.

Performance: play well. The other two items need to be improved.

　　　　In this part, we will have a most detailed comparison from CPU, GPU and the overall running score through three mainstream running scores. This test is the most objective confrontation, and a high score means strong performance. In addition, I will also test the fluency of these three models when running large-scale games respectively.

　　　　The HiSilicon Kirin 659 eight nuclear processor is adopted. This processor is an upgraded version of Kirin 650, and the highest frequency can reach 2.36GHz. Due to the 16nm process, this processor is particularly excellent in power consumption and heat generation, which can bring a stronger performance experience.

　　　　　2 equipped with Snapdragon 660 mobile platform, this processor must be familiar to most mobile phone enthusiasts. It is worth mentioning that,Snapdragon 660 mobile platform is the first time to introduce HVX (Vector Extension) based on the whole DSP processing in Snapdragon 600 series, which can provide very large throughput and handle a lot of operation work at a faster speed, which has great applications in graphics processing, computer vision and neural networks.

　　　　Qualcomm Snapdragon 625 mobile platform is used, and the graphics processor is Adreno 506. This chip has eight cores, the highest frequency is 2.0GHz, and it adopts 14 nm process technology, so it has sufficient performance and low power consumption. Since the Youth Edition does not support the installation of Geekbench 4 for the time being, there is no comparison of this item for the time being.

　　　　I believe that many netizens usually measure the performance of mobile phones by running scores. However, if we objectively evaluate the comprehensive experience of mobile phones, it is of little significance to run points. Because when running a score, the processor usually tries its best to brush the score. However, in daily use scenarios, in order to control the balance between performance and power consumption, the performance of the processor will be limited. For example, when running scores, eight cores may rush to brush scores together, while the daily operation state may be "one core works and seven cores watch".

　　　　Let’s talk about the significance of running score software. The function of running score software is to quantify the performance and show the peak performance of a chip in the form of digital score, which is simpler and easier to understand than technical terms. Here, we need to pay attention to a word: "peak performance". Yes, most running score software measures the peak performance, that is, the ultimate performance of the chip, but it may not work so hard in daily use.

　　　　Therefore, although the three models didn’t get high running score data, they still won a large number of users to buy and use with their perfect system optimization and stable thermal control.

Endurance: Charging "off the charts" has good endurance.

　　　　　　　　The endurance test is divided into two parts. The first part is the charging test. The author starts charging three models from 0% at the same time, and records the power every 5 minutes for a total of 30 minutes. The second part is endurance test, which adopts Zhongguancun online 5-hour heavy use model. The test results are as follows.

　　　　As you can see, of the three mobile phones, 2Support QuickCharge 3.0 fast charging,Half an hour is the fastest charging speed, charging 50% of the power, followed by Charm Blue Note 6, charging 35% in half an hour, which needs to be improved.

　　　　The power consumption test results are obvious, and the low energy consumption advantage of Snapdragon 625 equipped with Charm Blue Note 6 is revealed.Actually, 59% of the power remained, which greatly exceeded my expectation for this mobile phone. I didn’t expect Meizu to control the power consumption of Snapdragon 625 so well, and this achievement is also the top level in our database.

summary

　　　　After reading the comparison of the three thousand yuan double cameras in this issue, I don’t seem to have clearly ranked the total accurately. Generally speaking, the three thousand yuan double cameras have sufficient characteristics and advantages.

　　　　If you are value-controlled, and have no high pursuit of performance, Youth Edition is your best choice; If you are more inclined to "features" and are keen on the small design and functions of mobile phones, Nut Pro 2 will give you a heart-warming feeling; The economy is not affluent, and just like having a practical, beautiful-looking, non-card mobile phone, Charm Blue Note 6′ s high cost performance beckons to you.

　　On March 29, 2023, local time, Ukrainian soldiers stood in front of a tank in the Donetsk region. Vision china diagram

　　Senior US government officials revealed that confidential documents about NATO and the United States assisting Ukraine in preparing for war were leaked and appeared on social platforms this week. The Pentagon is investigating this.

　　According to a report by The New York Times on April 6, these leaked documents detailed a secret plan of the United States and NATO, which planned to help Ukraine prepare for the spring counterattack against Russian troops. The leaked documents appeared on social platforms such as Twitter and Telegram. Telegram is a social platform widely used in Russia.

　　The report quoted military analysts as saying that some parts of the leaked documents seem to have been revised, exaggerating the US estimate of the number of Ukrainian people killed in the conflict and reducing the estimate of the number of Russian people killed. Although there are traces of revision, the document still discloses information about weapons delivery, troop setting, strength, action plan and so on.

　　Officials of the US President Biden’s government tried to delete these leaked information from the Internet, but as of the evening of April 6, local time, it was still unsuccessful.

　　The New York Times said that the leaked documents did not provide a specific operational plan. Besides, these documents have been out of date for five weeks. However, these documents can provide analysis materials for military personnel.

　　According to Reuters’s report on April 7, Ukrainian government officials said that the leaked documents were "false intelligence actions" by the Russian side, aiming at "spreading doubts" about Ukraine’s counter-offensive plan.
