There are also lower-priced products like vivo, Big Cola, and Desai, and how to choose depends on everyone’s needs.

Reveal the 3 major routines behind the legality of online car-hailing!

　　[Pacific Automobile Network, Industry Channel] When Didi and Kuaidi were on sale in 2014, it was a loss to go out and not take a taxi. It would be really good to be a good driver, and there would be no such thing as cracking down on black cars. Speaking of big things in the world, we will be together for a long time, and it is more distressing to burn money, right? As a result, Didi Kuaidi merged in early 2015.

　　At that time, I felt okay, because thanks to Uber’s timely entry into the competition, there were still a lot of coupons for the people who ate melons. With the development of the taxi business, Didi played a variety of tricks such as express cars, hitchhiking, and special cars. A large number of private cars were connected to the taxi platform, and taxis were indeed more convenient and fast. This period of brutal growth also exposed many problems. For example, if there were more people taking taxis in the morning and evening rush hour, would the city be more congested? A large number of drivers entered the platform, causing frequent passenger safety problems. In addition, it was particularly important to seize the territory of taxis. This period was also a period of high disputes between taxi drivers and taxi platforms.

Shijiazhuang taxi driver smashes foreign rental

　　Can the old and new business forms sit in rows and share the fruits? Impossible! The government and taxi drivers say that your online car-hailing is a black car! We want to crack down on black cars! Didi Uber said that we are a sharing economy, and we are committed to mobilizing resources to solve travel difficulties. How on earth can we do this? The Ministry of Transportation has not officially issued a document. Online car-hailing has grown into giants while being beaten up. It is already a subconscious habit for most young people to go out and open Didi or Uber, and the market that has burned no less than 10 billion has been cultivated!

　　Finally, on July 28, 2016, a day destined to be recorded in the history of taxis, the central government’s regulations on the management of online car-hailing were issued. The people who were supported by coupons praised it one after another, and it was a cheap taxi! Take a look at the picture below to feel it.

　　However, 4 days later, Didi merged with Uber! Speaking of major events in the world, it must be combined for a long time, this is all a routine! After learning that Didi acquired Uber, the mood of the melon eaters was immediately different. Take a look at the picture below to feel it.

　　Before discussing the issue of whether there will be cheap cars in the future, it is necessary to see the essence of the online car-hailing management method clearly. If you have the patience to read the official release of a "guiding opinion", a "temporary measure", and a "service specification", you will find that there are many routines, and the spring of online car-hailing is over!

　　First, let’s take a look at the official tone set for online car-hailing, "Prioritize the development of urban public transportation and moderately develop taxis, according toHigh-quality service, differentiated managementThe principle of orderly development of online car-hailing ".

　　Students pay attention, high quality and differentiation are the key points, especially from the perspective of the details, the requirements for online car-hailingBasically, it points to the existing special car.: "In-vehicle facility configuration and vehicle performance indicators should besignificantly higher thanLocal mainstream cruise taxis should provide Internet wireless access, mobile phone chargers, paper towels, etc. for passengers to use. "

　　And online car-hailing "should not patrol to pick up customers, and should not set up unified cruise car dispatch service stations at airports, railway stations, etc., or pick up customers in places where waiting in line is implemented." After the online car-hailing was subordinated to the management of the local transportation authorities, the original taxi was in charge, but now it is also in charge of online car-hailing. Taxi companies can calm down, we are our own relatives!

　　There were no bright spots in this taxi reform either, although it was mentioned that "all new taxi operating rights will be used free of charge" and "paid user fees will be gradually abolished". The amount of new additions was originally small, and there was no specified time limit for the gradual cancellation, which means nothing was said, especially when it comes to the issue of brother’s money, it is only mentioned as "equal association". Equal negotiation? According to the previous routine, the negotiation has to wait for the brothers to go on a collective strike, right? This is purely spiritual support for my brother.

Taxi money

　　This time, the online ride-hailing management method is like a "black jade intermittent cream" for traditional taxis. It will not be replaced. Even if it is complained, it will continue to exist as a cruise taxi.

　　This time, in addition to setting the tone and general norms, the specific management authority has been delegated to the local government, so the local government is the final speaker. It is expected that the policies of various places will require the following three major routines.

　　Routine 1: Price control, is this the rhythm of price increases?

　　Traditional taxis are priced by the government, and online car-hailing is no exception. "It shall not operate at a price lower than the cost to disrupt the normal market order." "Online car-hailing freight rates are subject to market-adjusted prices. The city people’s government believes thatExcept where it is necessary to implement the government-guided price"…"

　　And the performance of online car-hailing stipulated by the government is significantly higher than that of taxis, which is bound to increase the cost of taxi-hailing. Especially after the merger of Didi and Uber, can the people who eat melons still care about the promotion as much as before?

　　Although Didi officials have said that there will still be discounts, it is conceivable that areas with promotional incentives must be areas that need to expand, and the extent and scale of promotion will not be as good as before. After all, the government stipulates that the price must not be lower than the cost price to disrupt the market.

　　Will the price increase? Didi and Uber have already completed a large-scale price increase between June and July. The cost of Didi Express per kilometer has increased from 1.5 yuan to 1.8 yuan, and the cost per minute has increased from 2 cents to 3 cents. Uber’s cost per kilometer has increased from 1.5 to 1.79, and the cost per minute has increased from 2.5 to 30 cents. With the fluctuation of oil prices and the increase in hardware costs, future price increases are really possible.

　　In terms of price, it is impossible to get a cheap car. While providing fast and comfortable service, the price will also return to the cost line, which will be the new normal for online car-hailing prices!

　　Routine 2: Quantity control restricts expansion

　　Although national-level policies do not specify whether to implement quantity control on online car-hailing, it is conceivable that quantity control will definitely be standard.

　　As for Wu, the Wuhan traffic control department said that according to the investigation situation, it is necessary to see whether the number needs to be controlled, and the number should be controlled. They said that the formulation of the plan is not blind, and a process of investigation is required to see how big the market demand is and how much online car-hailing needs to be put into consideration.

　　Routine 3: Access control drives up administrative costs

　　Online car-hailing platforms, online car-hailing, and online car-hailing drivers all need to apply for a license, which is natural, but specific to various places, "The city people’s government issues the" Online Booking Taxi Transportation Certificate "to online car-hailingIf otherwise stipulated, from its provisions…

　　"The specific standards and operating requirements of the vehicle shall be determined by the corresponding taxi administrative department…Determined according to the actual local situation". Combined with the actual local situation, for example, if the online car-hailing operation in Guangzhou is purchased uniformly, can it work? Obviously not satisfied!

　　In general, the regulations on online car-hailing at the national level still respect market-oriented operation, but the authority delegated to local governments is very large, or is this itself a routine?

　　All localities can have their own version of management, and they will be introduced before November 1. Is it to streamline administration, delegate power, or strictly govern? Is it to encourage innovation or maintain stability conservatively? In addition to the orientation of local governments, the power rent-seeking that may be brought about by various controls is also worthy of vigilance.

　　What is this called? This is called God closing a door and then using it to clamp your brain.

　　The sharing economy essentially improves resource utilization on the basis of mutual benefit. Uber is a typical representative of the sharing economy. It absorbs private cars to engage in online car-hailing services. But after the New Deal, can private cars be directly converted into special cars? The measures stipulate that "online car-hailing services shall not be provided in the name of private passenger car sharing."

　　Therefore, the private car must change its operating nature, purchase the corresponding commercial insurance, obtain the corresponding license, and then meet certain requirements for the age and condition of the car, such as installing satellite positioning devices, emergency alarm devices, and not recording 12 points in the last three consecutive scoring cycles.

　　Such a threshold will obviously repel a lot of original intention to do carpooling/ride-hailing private cars, and the original full-time network car owners, in view of the hard requirements of the vehicle, a number of economical private cars may be cleared.

　　Since it is called the sharing economy, it is also an essential part to benefit drivers. At present, the share of drivers on the Didi platform is about 20%. Will the share be increased after the merger? Will the incentive be reduced? At present, Xi’an Didi drivers have revealed to the media that since August 4th, Didi has reduced the reward for all private car franchise drivers by 80%. It is expected that all rewards for private car franchise drivers will be cancelled next.

　　As an ordinary person who has received Didi discounts, he belongs to a group that is more sensitive to taxi prices. He has never played the special car himself. Fortunately, the essence of poverty is not unique to me.

　　According to a report by Peking University, from the characteristics of riders, young people and migrants are more likely to choose online car-hailing trips. This shows that online car-hailing is becoming an effective tool to ease the "travel difficulties" of people without (qiong) cars (ren). But the new online car-hailing clearly refers to high-end special cars. Do you have to honestly squeeze the bus and subway? Has the sharing economy gone to see Marx?

　　Conclusion:

　　For Youshi, online car-hailing is just a new form of taxi, and it needs to be controlled. Although the new policy takes care of the vested interests of traditional taxis and constrains online car-hailing, I am not worried about online car-hailing at all, because the new technology is unstoppable. Especially a local snake like Didi, with its size and influence, actually occupies a great advantage in the market competition.

　　Taxi is just the first step. The unified Didi will become a huge transportation platform entrance in the future. On the basis of optimizing big data processing capabilities, it will be able to develop diverse services and achieve far more commercial value than it is now.

　　It’s just that the monopolistic ride-hailing platform has become the strong party. Didi’s current valuation has reached 27 billion US dollars. In the face of such a huge business empire, drivers and passengers have no bargaining power at all. As a result, the share of the national market, similar to molecular money, makes the ride-hailing platform actually become another kind of taxi. In the short term, the various hardware costs and administrative costs brought about by the game between the ride-hailing platform and the local government will naturally be passed on to consumers. So, the next question is – do I want to buy a bicycle or a battery car?

Beijing released ＂Thirteen Questions on Haze Protection＂

　　CCTV News:In order to help you prevent haze scientifically, today (9th), Beijing Municipal Health and Family Planning Commission and Beijing Municipal Center for Disease Control and Prevention released.Thirteen Questions about Haze Protection.

　　1. What is haze?

　　Haze is a kind of weather phenomenon that a large number of tiny dust particles, smoke particles or salt particles are suspended in the atmosphere, which makes the air turbid and reduces the horizontal visibility to less than 10 kilometers. Haze is generally milky white, which weakens the color of objects, making bright objects in the distance reddish yellow and dark objects reddish blue.

　　Relevant research conducted by Beijing CDC in 2013-2015 found that the main components of smog are water-soluble inorganic ions (nitrate, sulfate and ammonium salt ions, etc.), metals and metalloids (lead, cadmium, arsenic, etc.), and carbon substances (organic carbon and inorganic carbon).

　　2. Does smog affect the human body?

　　Smog has an impact on the human body! According to the data, the impact of smog on human body is generally divided into direct impact and indirect impact.

　　Direct impact: When the concentration of air pollutants rises sharply in a short period of time, people may cause acute harm by inhaling a large amount of pollutants, resulting in respiratory tract and eye irritation symptoms, such as cough, sore throat and headache. If it is exposed for a long time, it will cause chronic inflammation, decreased immunity and allergies.

　　Indirect effects: smog can affect our health through long-term indirect effects, such as affecting solar radiation and microclimate, producing greenhouse effect, destroying ozone layer and forming acid rain.

　　3. Why should we reduce outdoor activities in foggy weather?　

　　Relevant research conducted by Beijing CDC in 2013-2015 shows that the indoor PM2.5 concentration is 30% to 40% lower than the outdoor concentration in severe haze weather, so it is suggested to minimize outdoor activities in haze weather.

　　4. Do you want to wear a mask when the smog comes? How to choose? How to wear a mask correctly?

　　If you have to go out in foggy days, wearing a mask is the most important protective measure. Any mask has a certain protective effect, but it is recommended to choose a mask with good protection.　

　　According to national standards, the protection level of masks is divided into four levels from low to high: D, C, B and A, which correspond to different air quality conditions.

　　Grade A corresponds to "serious pollution" and is used when the concentration of PM2.5 reaches 500 micrograms per cubic meter. Grade d corresponds to "moderate and below pollution" and is suitable for situations where the concentration of PM2.5 is less than or equal to 150 micrograms per cubic meter.

　　Wearing a mask should follow the instructions for use. When wearing, you must completely cover your nose, mouth and chin, and keep the mask close to your face. The better the tightness, the better the protection effect.

　　5. What should I pay attention to when wearing a mask?

　　Not everyone is suitable to wear a mask. The tight structure and filter material of the mask will increase the respiratory resistance and reduce the comfort.

　　Different groups of people should pay attention to wearing masks: pregnant women should pay attention to their own conditions and choose products with better comfort, such as protective masks with exhalation valves to reduce exhalation resistance and sultry feeling; Children are in the stage of growth and development, and their faces are small, so it is difficult for general masks to achieve the effect of close fitting. It is recommended to choose children’s protective masks produced by regular manufacturers. When the elderly, patients with chronic diseases and special people with respiratory diseases wear masks, it is recommended to use them under the guidance of professional doctors.

　　Masks are not suitable for wearing for a long time. On the one hand, pollutants such as particulate matter are adsorbed on the outside of the mask, resulting in an increase in respiratory resistance. On the other hand, bacteria, viruses, etc. in exhaled breath will also accumulate inside the mask. Failure to breathe fresh air for a long time will make people’s own immunity decline.

　　Non-disposable masks should be cleaned regularly, and the filter membrane should be replaced. When they are not worn, they should be kept properly.

　　6. How to pay attention to personal hygiene after going home for outdoor activities in foggy weather?

　　After going out for activities in foggy weather, clothes, nose and mouth, and bare skin will be attached with a large number of pollutants in the smog, which will be harmful to health. Therefore, it is suggested to take off your coat, wash your face, wash your hands, and wash your mouth and nose in time to reduce pollution.

　　7. Why should children and the elderly pay more attention to smog protection?

　　Children are in the stage of growth and development and are more sensitive to the environment than adults. The elderly have low body resistance and usually suffer from basic diseases. A large amount of dust and particles in the smog will stimulate the respiratory tract and easily cause respiratory irritation symptoms. Therefore, children and the elderly should pay more attention to the protection of smog.

　　8. What should I do if there are symptoms such as cough and sore throat in foggy weather?

　　The acute harm caused by people inhaling a large amount of pollutants in haze weather is mainly manifested in respiratory tract and eye irritation symptoms, such as cough, sore throat, red swelling and tears in eyes, etc. It is suggested that symptomatic treatment be taken when necessary to alleviate the symptoms.

　　It is suggested that sensitive people with basic diseases should reduce outdoor activities in foggy days, but also reduce to crowded places with dirty air, pay attention to personal hygiene, wash their hands frequently, and pay attention to increasing or decreasing clothes at any time to maintain good physical condition.

　　9. How do families choose air purifiers?

　　The air purifier has a certain effect on purifying the air. When selecting, the first thing to do is to make clear the purpose of use, and to buy a purifier with purification effect on PM2.5.

　　Second, we should pay attention to the performance indicators of the purifier. According to national standards, a truly effective air purifier should achieve the energy efficiency index of "three highs and one low".

　　High clean headroom: The clean air volume (CADR) is the purification effect index of the purifier. The greater the CADR value, the stronger the purification ability of the purifier and the better the purification effect.

　　High cumulative purification capacity: The higher the cumulative purification capacity (CCM) value, the more pollutants to be purified and the longer the life of the filter screen.

　　High energy efficiency value: The higher the energy efficiency level, the more energy is saved.

　　Low noise level: the working noise of the instrument is generally lower than 50 decibels, which is relatively quiet. When purchasing, you can observe the prototype for intuitive feeling.　

　　Thirdly, in order to achieve the purification effect, the air purifier must be turned on for a certain period of time according to the room area, the power and purification efficiency of the purifier, so as to effectively reduce the pollution degree of indoor pollutants. Pay attention to the product manual when purchasing. Generally, the product manual indicates the test report or certificate of conformity issued by the air purification effect testing unit. Products that have not given experimental conditions and are too simple or even absolute should be purchased carefully.

　　10. What should I pay attention to when using the air purifier?

　　Attention should be paid to the purification effect of the air purifier during use, and it is suggested to replace or clean the filter material according to the product instructions. If it is found that the purification effect is obviously reduced, or that there is an odor after the air purifier is turned on, it is necessary to replace the filter material and clean the filter in time. Moreover, the purification materials in the air purifier also have a service life. In order to avoid secondary pollution, they should be replaced in time according to the pollution degree and service time. When indoor pollution is serious, the replacement frequency of filter media can be increased. Self-protection should be done when replacing the internal materials of the air purifier. For example, gloves and masks should be worn when replacing the filter screen to prevent contact and inhalation of trapped harmful substances during replacement.

　　11. Does smoking affect indoor air?

　　Indoor smoking has a great influence on indoor air. The experimental data of Beijing CDC show that the indoor PM2.5 concentration can reach more than 500 micrograms per cubic meter when one cigarette is burned in a 30 cubic meter experimental cabin. Therefore, it is recommended to avoid smoking indoors in foggy weather.

　　12. How do families cook reasonably in foggy weather?

　　Home cooking is also an important source of indoor PM2.5 Relevant research by Beijing CDC shows that the instant PM2.5 concentration can exceed 800 micrograms per cubic meter even if the cooking methods such as frying, frying and frying are used in the kitchen (doors and windows are closed). And can spread to the living room, bedroom and so on to a certain extent. However, the concentration of PM2.5 in the kitchen does not change much when cooking by steaming or boiling.

　　Therefore, it is suggested that when cooking in foggy weather, the kitchen door should be closed and the range hood should be turned on; During the period of heavy pollution, try to steam and cook; After cooking, you should continue to turn on the range hood for 5 to 15 minutes.

　　13. How to pay attention to the indoor environmental sanitation in foggy weather?

　　The indoor activities of human beings increase in foggy weather, which will lead to the gradual increase of indoor PM2.5 concentration when doors and windows are closed. Therefore, in heavily polluted weather, wet cleaning method should be adopted for indoor cleaning, and wet mops and rags should be used for indoor cleaning, and the frequency should be increased appropriately. If the smog clears, open the window in time for ventilation for at least 15 minutes. (CCTV reporter Zhang Jing)

Military newspaper articles talk about soldiers’ live broadcast： confidentiality first and will explore and spread the image of soldiers

　　Topic backgroundIn 2013, the domestic online live broadcast platform began to rise; In 2015, there were nearly 200 online live broadcast platforms with 200 million users. With the popularity of 4G and wireless networks, the habit and demand of netizens watching videos on the mobile Internet are being cultivated, and everyone can become a "live car". Some media said that the "national live broadcast era" is coming.

　　With only one smart phone and one software, life in the military camp can be "broadcast live". Going back ten years is unimaginable for many people. As smartphones enter the military camp in an orderly manner, the "mobile phone live broadcast" platform has also been favored by many officers and men. At the same time, the live broadcast has also brought new problems and challenges to the army management. Facing the "mobile phone live broadcast fever", a recent experience of a regiment of the 14th Army of the Army may bring us some enlightenment.

　　"Push-ups" on the live broadcast platform

　　At the beginning of June this year, Xiao Wang, a noncommissioned officer of a regiment of the 14th Army of the Army, downloaded a mobile phone live APP and registered an account during his vacation. Every day, he does push-ups, singing and other programs. In less than a month, the number of fans has soared from zero.

　　After returning to the team, Xiao Wang’s "live broadcast" was interrupted. I can watch my account constantly "dropping powder", and Xiao Wang is a little anxious. One weekend, Xiao Wang resumed the long-lost "live broadcast". After the company cadres found out, they immediately stopped.

　　Coincidentally. Xiaoshi, a battalion secretary, likes playing games since he was a child. He was a "game anchor" when he was in college. Last year, after re-using his smartphone, he joined the "live broadcast" of the game, and sometimes used the weekend to anchor online game competitions. Once, a fan guessed Xiaoshi’s military status in the live broadcast and asked him about the army. Xiaoshi suddenly became alert and stopped the live broadcast.

　　It has been found that many officers and men use the "mobile phone live broadcast" platform one after another, which makes the first battalion pay attention to this issue. Although most officers and men do not have "live online", there are also many people who "watch live". Some live content is not nutritious, and some are even mixed with negative information. The first battalion immediately stipulated that officers and men should not use the "mobile phone live broadcast" platform.

　　It didn’t take long for a comrade-in-arms to post on the Youth League’s political work website with the topic "Is it really wrong to broadcast live on mobile phones?", which triggered a discussion.

　　discuss about sth enthusiastically

　　How does the military camp view "live broadcast"?

　　“‘ Mobile phone live broadcast ’ It is no accident that it can be fired. " Zhao Zhang, a company soldier, said that he likes to record the moments around him with his mobile phone when he is on vacation. A touching scene is presented through live broadcast, which is more likely to resonate with everyone than empty preaching.

　　"My favorite anchor often shares some practical skills in daily life." Peng Yuxi, a female soldier, watched the live broadcast on weekends. Every time she watched it for a short time, she gained a lot. Not long ago, she applied the storage skills learned from the live broadcast to the loading of carrying materials, which greatly improved the space utilization of carrying tools. This storage method was also used for reference by other officers and men in thy company, and everyone said it was good.

　　In sharp contrast, some battalion chiefs frown at the mention of "mobile phone live broadcast". Some people think that if it is not strictly controlled, live broadcast software can easily turn mobile phones into "grenades." Instructor Ruan Liedong warned: "If you are not careful, if you put military secrets ‘ Live broadcast ’ What should I do if I go out! "

　　In addition, the content of the "mobile phone live broadcast" platform is also worrying. The instructor of the 3rd Battalion said to Lei, "The reason why I object ‘ Live broadcast ’ It is worried that the officers and men are not strong in discriminating ability, and the live webcast content is varied and bizarre, which makes it easy for young soldiers to indulge in it. " He once found that some soldiers wasted a lot of money to give virtual gifts, and even became "moonlight clan".

　　The heated discussion among officers and men attracted the attention of Liu Jijun, the political commissar of the regiment. “‘ Mobile phone live broadcast ’ It is an emerging product in the era of mobile Internet. When QQ and WeChat just emerged, the army did not let everyone use it. But it turns out that blind prohibition is a kind of ‘ Ostrich mentality ’ 。” Liu Jijun believes that "mobile phone live broadcast" does have certain hidden dangers, but it is not completely harmful. Barracks have their own particularity, and new things can neither be left unchecked nor banned at once. Instead, we should strengthen supervision while doing a good job in education and guidance, and unblock them simultaneously.

　　"Education+Supervision" Facing the Challenge

　　The more you argue, the clearer you become. A group of party members of the group quickly reached a consensus that there is nothing wrong with "mobile phone live broadcast" itself, but the time, place, method and content of its use must be clearly regulated and restricted.

　　To this end, Liu Jijun prepared a special lecture for all officers and men to educate and guide officers and men to treat "mobile phone live broadcast" rationally. The regimental organs carefully sorted out the problems that are easy to occur in the "mobile phone live broadcast", invited the network engineers of the automation station to conduct technical analysis and answer questions on the spot, and timely launched a photo exhibition of network security warning education to enhance the awareness of network security prevention of officers and men.

　　"The existing laws and regulations do not explicitly restrict the use of ‘ Mobile phone live broadcast ’ Software, but without approval, soldiers can’t expose their military identity on the Internet. Confidentiality is always a top priority. " Liu Jijun said that in order to strengthen supervision, the regiment refined and improved the "Regulations on the Management of the Use of Smartphones", stipulating that officers and men can only watch and conduct "live broadcasts" in the designated areas of military cafes on vacation or in casual clothes, and the content must not be related to the troops, and the military identity cannot be revealed; When performing tasks or under other special circumstances, you must disable functions such as camera shooting on your mobile phone.

　　The group also developed smart phone management software and set up network supervisors in each company to find and correct violations in time. Not long ago, soldier Xiao Li just wanted to broadcast his physical training live in the company fitness room, but he was found and stopped. In addition, in order to prevent the erosion of bad information, the group actively cooperated with the resident network supervision department to grasp the situation of the mobile phone live broadcast platform with illegal problems for the first time and put it on the "list of prohibited software".

　　"Through management education, officers and men are now right about ‘ Mobile phone live broadcast ’ The use of the platform has a clear specification. ‘ Mobile phone live broadcast ’ With media attributes, after reporting to the higher authorities for approval, we will consider exploring the use of live broadcast platforms to spread the good image of military personnel in the future. " Liu Jijun said.
