　　Recently, it was revealed that the relevant departments issued a new regulation on webcasting dramas: from now until June, all online dramas, TV dramas and online movies with costume themes, including martial arts, fantasy, history, myth, crossing, biography and palace fighting, are not allowed to be broadcast. Remove all the pages that have been broadcast, and arrange all the ones that have not been broadcast another day. Under the new regulations, many costume dramas, such as The Legend of the New White Snake, A Letter from the Pillow of Sansheng Sanshi and Joy of Life, will be affected.

　　However, the reporter found that although many people in the industry affirmed this trend. But up to now, the website of the State Administration of Radio, Film and Television has not issued a notice. Costume dramas such as "East Palace", "Swinging" and "Eternal Dragon Slayer" are still being updated normally on video websites.

　　"Trilogy": Transfer to Network, Offline and Backlog

　　This year, costume dramas have been broadcast, and many of them occupy the scenery. For example, the big IP adapted the screenplay "East Palace", recently won the championship of the whole network heat week, and became the online drama with the largest barrage, and also made a bunch of fans named "East Palace Girl". However, for the dramas listed in the video websites to be broadcast in 2019, such as The Longest Day In Chang’an Joy of Life’s "A Letter to the Sleeping Lady of Sansheng Sanshi", The Biography of Sun Ruowei, The Mysterious Record of Kyushu, Chang ‘an in the World, The Lonely City is Closed, and The Poems of Dasong Palace will be affected by the "ancient restrictions". Among them, Joy of Life’s six films, Biography of Imperial Concubine Sun Ruowei, Young Tales of the Song Dynasty, Doubtless Pride, Poems of the Palace of the Song Dynasty, and The Mysterious Record of Kyushu, are still costume dramas to be broadcast by five David TV stations.

　　In addition, "The Legend of the New White Snake" recently announced that it would be broadcast alone in iQiyi on March 27, and as a result, it was announced that it would be "suspended due to schedule adjustment", and the launch conference was also cancelled. The "Chang ‘an in the World", which was suspected of touching the red line, was "even worse". In 2018, it suffered two withdrawals, and the series was cut from 68 episodes to 48 episodes. The director once wrote that "I don’t even know if I change it again." With an investment cost of 500 million yuan, it is still a question whether the company can recover its capital.

　　As early as 2018, the industry was rumored that costume dramas were strictly controlled. The two great dramas, Biography of Ba Qing and Ruyi’s Royal Love in the Palace, have a bumpy fate, and the former is still overstocked. "Fire is like a Song", "Lonely World" and "Secrets of the Three Kingdoms" were also webcast. In the beginning of 2019, the online Kung Fu drama was completely banned, and the second round of Ruyi’s Royal Love in the Palace and Story of Yanxi Palace broadcast by Satellite TV was also stopped. Plays such as "Shake Up" and "My Little Girl Never Abandons" only landed in the Weekly Theater of Satellite TV.

　　Today, the "ancient order" has been upgraded again. The story of Xi Fei, which invested 60 million yuan to build a shed, was notified to stop working. Chen Qiaoen was originally invited to star in Tencent’s self-made TV series "Yanyuntai", and the contract was also cancelled.

　　The popular costume dramas "East Palace", "Swing" and "Eternal Dragon Slayer" recommended by the three major video websites have disappeared. In addition, Weibo, the original producer of "The Queen of Dugu" @ Mr. Beixi, said that "The Queen of Dugu" will be permanently offline after the finale, and then said that it will disappear completely on the 25th, which may be related to the new regulations.

　　Content and business orientation have been "severely cracked down"

　　In fact, costume dramas have many fans. What is the problem? In April 2018, Nie Chenxi, director of the State Administration of Radio and Television, clearly pointed out at the national TV drama creation planning meeting: resolutely oppose historical nihilism, arbitrarily misinterpret history, derogate and blaspheme classic traditions, and tamper with important historical events and historical figures that have reached consensus and conclusion. Fantasy, Xianxia and overhead interpretation of costume dramas can’t be made up to increase entertainment and attract attention.

　　On January 25th, the official blog of Beijing Daily published a document listing the "five sins" of Gongdou Opera, which was regarded by the industry as the clue of this wave of "ancient restrictions".

　　Specifically, the drama of the heroine, such as Biography of Sun Ruowei, the Imperial Concubine of Daming, and Old Friends of Jiangshan, which involves the struggle between the court and the court, may face deletion. However, many film and television companies have turned to the machiavellian machiavellian dramas after the heroine’s drama encountered a bottleneck in the market. However, at present, Joy of Life’s machiavellian dramas such as He Lai Hua Ting, Sword Dynasty and Your Highness the Wolf are also quite dangerous. As for the direction of historical dramas such as Chang ‘an in the World, Lonely City Closed, and Poems of the Song Dynasty Palace, it still depends on whether the plot deviates too much from history and whether the value orientation is correct. In addition, according to the analysis of the insiders, the rising copyright fees for the single episode of Gongdou drama have also led to excessive pursuit of commercial interests.

In recent years, more and more new energy vehicles have entered our sight. Whether it is the improvement of travel awareness or the helplessness of being forced to shake the number, in short, some consumers have already started to buy. Of course, one of the important reasons why new energy vehicles can enter people’s homes is the dual action of national and local subsidy policies, but in the face of these complicated policies, do you really understand them? Which "black boxes" are mixed with them, and you haven’t noticed them? Below, let’s talk together.

● "Double-decker" subsidy for new energy vehicles

If we talk about subsidies for new energy vehicles, perhaps most people know that "national+local" will give subsidies to consumers, but how much will the specific national and local governments make up? How to subsidize? Which new energy vehicles can enjoy? Maybe not many people fully understand it.

The first level: state subsidy policy.

In order to accelerate the development of the new energy vehicle industry, in September 2013, the relevant state departments issued the Notice on Continuing to Promote the Application of New Energy Vehicles, which made it clear that in 2013 -2015, consumers will continue to be subsidized to buy new energy vehicles.

First of all, the scope of subsidies is new energy vehicles that are included in the scope of central financial subsidies, and the vehicles meet the requirements (what are the requirements? The third page details) pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Secondly, the state has made it clear that the new energy subsidies given are not for car companies and dealers, but directly for consumers. When buying new energy vehicles, consumers pay after deducting subsidies from the sales price.

Finally, it should be noted that the subsidy standard is decreasing year by year. This mainly takes into account the scale effect, technological progress and other factors. According to the notice issued by the state in February 2014, the subsidy standard was reduced by 5% in 2014 and by 10% in 2015.

The second level: local government subsidies

The country takes the lead in promoting new energy vehicles, and local governments naturally need to implement them. What’s more, in the Notice on Continuing the Promotion and Application of New Energy Vehicles issued in September 2013, it has clearly pointed out the demonstration areas that hope to "respond to the call" immediately, that is, Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and other areas with heavy fine particle control tasks.

I have to say that the response of local governments is indeed fast enough. In November 2013, the first batch of new energy vehicles were promoted and applied in the list of cities or regions (what does it mean to enter the list? The third page has been released, which covers the regional cities that were previously "named" by the state. Next, the editor will take four first-tier cities in North, Shanghai, Guangzhou and Shenzhen as examples to talk about the local subsidy policy for new energy vehicles.

Beijing:

In January, 2014, the Beijing Municipal Government issued the Administrative Measures for Demonstration and Application of New Energy Passenger Cars in Beijing. The policy shows that the subsidy for purchasing new energy vehicles in Beijing is consistent with that of the state, that is, the subsidy standard is determined according to the ratio of 1:1 between the state and Beijing. However, it should be noted that the total financial subsidies of the state and Beijing do not exceed 60% of the vehicle sales price at the highest.

In addition, Beijing only subsidizes small and micro pure electric vehicles and fuel cell vehicles, and plug-in hybrid vehicles in the state subsidy policy are not among them. At the same time, only the new energy vehicles listed in the Catalogue of Recommended Vehicles for Demonstration and Application of Energy-saving and New Energy Vehicles and those listed in the Catalogue of Production Enterprises and Products of Beijing Demonstration and Application of New Energy Passenger Cars can enjoy subsidies. At present, the catalogue has not been published. Therefore, it is uncertain which new energy vehicles can be shortlisted.

In addition to price subsidies, you can buy new energy vehicles that meet the "conditions" in Beijing, and you can also shake the number in the configuration indicators of special new energy passenger cars. The results of the first lottery will be announced on February 26th, 2014. According to the data released by the Passenger Car Indicators Office, more than 1,700 applications and confirmations for extension of individual demonstration application of new energy passenger car allocation indicators have been received. According to the rough calculation of the quota and allocation ratio of passenger cars in this city this year, there will be 1,666 new energy vehicle indicators distributed to individuals in each period. Although the number of applicants in the first batch is slightly higher than the quota and needs to be shaken, compared with ordinary cars, the 98% chance of winning the bid for new energy vehicles is already much higher.

Shanghai:

In 2012, Shanghai promulgated the Interim Measures for the Pilot Implementation of Encouraging Private People to Buy and Use New Energy Vehicles in Shanghai, in which plug-in hybrid passenger cars will receive a subsidy of 30,000 yuan each, and pure electric passenger cars will receive a subsidy of 40,000 yuan each, and special license plates can also be obtained free of charge (at present, the auction price of Shanghai automobile license plates is around 70,000 yuan-100,000 yuan). Of course, subsidized vehicles should also enter the Information Form of Pilot Vehicles for Private Purchase of New Energy Vehicles in Shanghai issued by the Shanghai Economic and Information Committee.

It is worth noting that the above policies expired at the end of 2012, and the new subsidy standards in Shanghai have not yet been introduced. However, the editor learned from the dealers in Shanghai that the purchase of new energy vehicles can still be implemented according to the old policy, and the new policy will be introduced in the near future, and the subsidy may be reduced.

Guangzhou:

In 2012, Guangzhou issued the Trial Measures for Purchasing Subsidies for Energy-saving and New-energy minibuses in Guangzhou, which showed that after vehicle registration, new-energy minibuses and hybrid vehicles with a fuel saving rate of more than 20% were given a subsidy of 10,000 yuan per vehicle. Although the amount of subsidy is small, and the subsidized models also need to enter the Catalogue of Recommended Models for Demonstration and Application of Energy-saving and New Energy Vehicles of the Ministry of Industry and Information Technology, the models include non-plug-in hybrid models, and in theory, more models will be subsidized.

In addition, according to the "Trial Measures for the Regulation and Management of the Total Number of Small and Medium-sized Passenger Cars in Guangzhou", all new energy vehicles that meet the "conditions" can also be shaken in the incremental indicators of 12,000 new energy vehicles in Guangzhou. Compared with ordinary cars, the chances of winning the lottery are higher.

It is understood that the "Trial Measures for Purchasing Subsidies for Energy-saving and New Energy minibuses in Guangzhou" will expire on March 31, 2014, and there is no continuous policy yet. Not long ago, Pan Jianguo, director of the Guangzhou Municipal Development and Reform Commission, revealed that in the future, Guangzhou citizens will be subsidized to buy new energy vehicles according to the ratio of 1: 1 between the central and local governments. In addition, citizens who buy new energy vehicles can also apply for a lottery directly. From this point of view, Guangzhou will soon adjust the existing subsidy and lottery policy for purchasing new energy vehicles to adapt to the national subsidy policy in the next few years.

Shenzhen:

In 2010, Shenzhen’s "Subsidy Policy for Private Purchase of New Energy Vehicles" was first introduced. At present, Shenzhen can enjoy the national and local 1:1 subsidy policy for purchasing electric vehicles and plug-in hybrid vehicles. It is also known that in the face of the new energy subsidy continuation policy issued by the state, Shenzhen is working on the relevant detailed rules for local new energy vehicle subsidies. The proposed plan may not be "decreasing year by year" like the central financial subsidy, but continue to adopt the original subsidy standards, namely, the maximum subsidy for pure electric vehicles is 60,000 yuan/vehicle, and the maximum subsidy for plug-in hybrid vehicles is 35,000 yuan/vehicle.

● Those "black boxes" mixed in the new energy vehicle policy.

After a general understanding of the national subsidy and local subsidy policies for new energy vehicles, most consumers will think that these policies are perfect. However, after editing and investigation, it is found that some key issues are very obscure, and they are like "black boxes". If we don’t open them one by one, we will inevitably have misunderstandings in the purchase of new energy vehicles.

It is not possible to buy new energy vehicles in any area.

It has been clearly pointed out in the notice on continuing to promote and apply new energy vehicles issued by the state that it will continue to promote and apply new energy vehicles relying on cities, especially megacities. If the conditions of demonstration cities or regions are met, an implementation plan for the promotion and application of new energy vehicles can be compiled and submitted to the four ministries and commissions, and the list of demonstration cities can be determined on the basis of merit.

In other words, only cities that enter the demonstration list can promote new energy vehicles, and local consumers can buy new energy vehicles locally and enjoy subsidies. At present, the four ministries and commissions have published two lists of cities or regions for the promotion and application of new energy vehicles, including first-tier cities in North, Shanghai, Guangzhou and Shenzhen, as well as urban agglomerations such as Hebei Province and Zhejiang Province. According to statistics, the two lists include 40 pilot cities or regions. If you want to know whether your place is a new energy demonstration city, you can click here to see [1] [2].

Not all new energy vehicles can enjoy state subsidies.

When understanding the national subsidy policy, we must carefully read the scope of subsidized vehicles, because not all new energy vehicles can get subsidies.

According to the Notice on Continuing the Promotion and Application of New Energy Vehicles, the new energy vehicles included in the scope of central financial subsidies should meet the requirements of pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Among them, the words "meet the requirements" mean that vehicles need to enter the Catalogue of Recommended Vehicles for Demonstration and Application of Energy-saving and New Energy Vehicles, and the vehicles that enter this catalogue are selected from the Announcement of Vehicle Manufacturers and Products of the Ministry of Industry and Information Technology, and only domestic vehicles such as independent and joint ventures will be included in this announcement.

After going around for so long, it’s actually a sentence—Imported new energy vehicles cannot enjoy state subsidies.

. Having said that, I believe many friends will question, isn’t the preferential policy given by the state to new energy vehicles just to promote energy conservation and emission reduction and promote air pollution control? So why is there a "nationality" when facing new energy vehicles?

In my opinion, the national new energy subsidy policy will shut out imported cars, so the scope of consumers will be reduced when buying cars; However, on the other hand, if subsidies are given to imported new energy vehicles, it is likely to increase their sales, which will certainly have an impact on self-owned brand vehicles and will not help China’s new energy vehicle industry to substantially improve. However, the subsidy policy is not to save the poor. Without core technology, it is impossible to speed up the industry by relying on policy subsidies blindly. Because the national policy has also given multinational car companies a new export-domestic.

Reading the Notice on Continuing to Promote and Apply New Energy Vehicles carefully, it is not difficult to find that the relevant policies issued by the state are first to accelerate the development of new energy vehicle industry. Although the subsidy policy refuses to import new energy vehicles, joint ventures can make imported new energy vehicles domestically or build joint-venture independent products to obtain subsidies. In this way, we can still leave some technology behind. At present, in fact, many joint ventures have set foot on the road of joint ventures and independent brands, and in order to comply with national policies, their first products have been designated as new energy vehicles, such as Dongfeng Nissan Qichen Chenfeng e30, FAW-Volkswagen Carrier Electric Vehicle, BMW Brilliance and so on.

Enjoy the "state" subsidy models, may not be able to get subsidies in the "local".

In theory, new energy vehicles that can receive state subsidies will naturally receive subsidies from local governments. But after investigation, it is found that this theory may not work everywhere.

For example, the new energy vehicles that enjoy local subsidies in Beijing do not include plug-in hybrid vehicles, and only pure electric vehicles and fuel cell vehicles that enter the Catalogue of Beijing Demonstration and Application of New Energy Passenger Cars, which is formulated by Beijing itself, can enjoy government subsidies.

When communicating with some dealers, the attitudes of dealers of different brands are also obviously different. A BYD salesman said, "Now you can’t get subsidies for buying e6 electric cars in Beijing, and it’s uncertain whether you will enter the subsidy catalogue in Beijing in the future.". In contrast, the dealers of Beijing Automobile are very confident, and the sales said, "Beiqi electric vehicles have entered the Beijing subsidy catalogue, and now they can enjoy a 1:1 subsidy when buying a car."

Not only in Beijing, but also in Shanghai, the sales staff of Roewe 4S store said that "E50 electric vehicles can enjoy subsidies". Another dealer said, "You can’t get subsidies for buying BYD e6 here". It is understood that only vehicles that enter the Shanghai new energy vehicle subsidy catalogue can enjoy local subsidies. At present, the Shanghai Economic and Information Committee has announced four batches, among which the local brand models Shanghai GM Sail SPRINGO electric vehicle and SAIC Roewe E50 were the first to be approved.

What causes the local subsidy policy to take more care of "local electric vehicles"? Some insiders said that this is the same as the state subsidy refusing to import cars, and it is "local protection". We won’t discuss this too much for the time being. After all, the first batch of subsidies in Beijing has not yet been issued, and the relevant rules for new energy vehicles in other regions have not yet landed. At present, the state has made it clear that the number of foreign brands in vehicles promoted and applied in demonstration cities or regions shall not be less than 30%. Do not set up or set up obstacles in disguise to restrict the purchase of foreign brand vehicles. Literally, the state’s attitude towards "local protection" is very firm, and we hope that this requirement will not become a dead letter when it is implemented and supervised.

New energy vehicles are not sold in all 4S stores.

In addition to policy-related matters, at present, some automobile manufacturers are not in place in the pre-sales service of new energy vehicles. Not long ago, the editor, as a potential consumer of new energy vehicles, tried to consult some information about new energy vehicles through the internet and telephone. From the result, the experience is not ideal.

On the official websites of some car companies, there is no detailed introduction to their electric vehicles. On some websites, even the place of sale is not publicized. The editor continuously called a brand’s 4S stores in three different regions to consult new energy vehicles, but they were all told not to sell them here, and a 4S store selling electric vehicles also introduced the local electric vehicle subsidy policy vaguely.

Here, I hope that manufacturers can quickly establish a set of perfect pre-sales and after-sales systems for new energy vehicles. At the same time, it is also suggested that potential users of new energy vehicles can consult the official 400 first to find out where the vehicles are sold, which can reduce useless work to some extent.

● Summary:

The subsidy policy itself is a catalyst for the development of new energy vehicles. The state and local governments go into battle together, so that consumers can get double benefits when buying new energy vehicles, which can effectively increase the sales of new energy vehicles. In addition, if we can make no distinction between "nationality" and "household registration", or at least get through the latter, so that new energy vehicles can be subsidized in more cities, perhaps new energy vehicles can develop faster in China.

Of course, it is far from enough to rely on policy support to promote new energy vehicles, and it is particularly important to rapidly develop the construction of related supporting facilities. At present, the state has made it clear that if applying for a demonstration city or region, it is necessary to formulate plans for the cumulative promotion of new energy vehicles and the construction of supporting facilities. Whether these military orders can be realized in future demonstration cities is worthy of attention. (Text/car home Qi Tianxiang)

　　Shortly after the bell rang on the first day of the promotion at 20:00 on May 13, 2025, the mobile phone that Ms. Fu of Dongguan City, Guangdong Province just placed in Tmall was delivered to her home by SF Brother. This is the first express delivery of Tmall 618 3C in 2025. This single delivery not only opened a new curtain for upgrading the logistics service industry under the dual-drive background of "national subsidy +618 promotion" in 2025, but also reflected the industry benchmark strength of SF as the head of the industry in terms of policy response speed, delivery stability and terminal execution ability.

　　Make up for the country and promote the rejuvenation of categories:

　　SF category expansion+intelligent collection to create a dual engine of state-funded logistics

　　In 2025, with the continuous promotion of the national subsidy policy, the national subsidy will expand its consumption in multiple categories at the 520 and upcoming 618 consumption promotion nodes. SF actively responded to the policy call, and comprehensively upgraded the full-link "rejuvenation delivery" solution for the "state subsidy" scenario, with multi-category expansion and AI testing technology capability guarantee.

　　First of all, in terms of service categories, SF has further expanded its support for "personalized rejuvenation" categories such as early education machines, electronic dictionaries and girlfriends machines on the basis of conventional high-frequency 3C categories such as mobile phones, smart wear, tablets and notebooks, and the service scenarios are closer to the needs of family users, parents and children and social gifts.

　　Secondly, in terms of terminal information collection capability, SF Express relies on mature terminal delivery system and intelligent terminal equipment to provide "one-stop collection of national compensation information" service to meet the requirements of product delivery startup/activation picture collection and serial code picture collection. Face-to-face on-site closed loop, and support the differentiated demands of different customers.

　　It is worth mentioning that in the face of massive subsidy delivery orders and the diversified implementation needs of customers such as e-commerce platforms and brand manufacturers in the subsidy scenario. For example, in the face of the difference of policies in different places and the different information collected by distributors of various platforms and sub-categories, SF Express can adjust effectively and quickly, support diversified verification methods, flexibly combine modules and go online quickly to meet the standards of subsidy rules in different categories and different places.

　　On the whole, SF has built its unique advantage in the state-funded delivery scenario: one-stop collection. The information collection process is embedded in the logistics node, and when the goods are delivered, the on-site collection of national compensation information is directly carried out to improve the overall service efficiency; Full link security. Ensure the safety of goods and accurate subsidies through multiple verification by means of serial code verification, AI detection and other technical means; Customized service. Support special customers’ demands for diversity collection of national compensation tasks.

　　Festivals are polite and rejuvenated quickly.

　　Shunfeng leads the national logistics track with professionalism.

　　This year, Tmall 618 countries made up for the first purchase, focusing on "spot, cheap and simple". Consumers can not only buy spot state-subsidized goods in advance, but also enjoy the state subsidy preferential treatment by superimposing the rights and interests such as promoting official reduction, large consumption coupons, interest-free installment and trade-in subsidies. Among them, the discounts for mobile phones, computers, flat-panel watches, digital products and other categories are as low as 50%. Among popular brands and single products, Apple dropped by 2,000 yuan, and iPhone16 Pro also entered the national subsidy for the first time, and the hand price was only 5,499 yuan. Chinese tonic goods can be delivered in time through SF Logistics, so that consumers can experience the happiness of promoting consumption in the first time.

　　The national subsidy policy has temperature, holiday gifts have attitude, and SF service has speed. The state subsidy policy is not only a key lever to boost the economy, but also a powerful path to improve people’s livelihood, optimize the structure and promote consumption. When the national subsidy policy overlaps with the "520" and "618" promotion nodes, SF Express, as a positive responder of the policy and a deep builder of scientific and technological logistics services, builds a solid delivery pillar for the temperature of the national subsidy policy with reliable professional guarantee, stable performance delivery and exclusive national subsidy service, providing consumers with a reliable path of trust and truly benefiting the people.

On May 19th, Huawei held a new product launch conference for nova14 series and HarmonyOS computers in Chengdu, and released two extraordinary masters of HarmonyOS computers, HUAWEI MateBook Pro and HUAWEI MateBook Fold. Among them, the extraordinary master of HUAWEI MateBook Fold, as the world’s thinnest commercial folding computer and the world’s largest commercial folding screen computer, not only created a new form of folding screen computer, but also became an important milestone in the application of Vivid Jingcai audio-visual technology on the PC side.

The treatment of blank wall is an important link in house decoration. Proper treatment can lay a good foundation for the subsequent decoration work, and also enable the wall to achieve the ideal decorative effect. The following is a detailed introduction to the treatment methods and related matters needing attention of the blank wall for you.

The first is grass-roots treatment. There are usually impurities such as dust, oil pollution and loose objects on the surface of the blank wall, which need to be cleaned comprehensively first. You can use brooms, vacuum cleaners and other tools to remove dust. For the parts with serious oil pollution, you can use cleaning agents to wipe them. If there are cracks, holes and other defects in the wall surface, it needs to be filled with gypsum or special repair materials. Small cracks can be directly repaired with putty, and larger cracks need to be embedded with bandages or mesh cloth before filling them to prevent cracks from cracking again.

The next step is wall leveling. Uneven wall will affect the subsequent decoration effect, so leveling is needed. Commonly used leveling materials are cement mortar and putty powder. If the deviation of wall flatness is large, coarse leveling can be carried out with cement mortar first, and fine leveling can be carried out with putty powder after drying. When daubing putty, it is generally necessary to daub it for 2-3 times, and the interval between each time should be determined according to the weather and material description, usually 1-2 days. The thickness of each application should not be too thick to avoid cracking.

Then it is sanded. After the putty is dried, it is necessary to polish the wall surface with sandpaper to make the wall surface smoother and flatter. The mesh number of sandpaper should be selected according to the flatness and grinding stage of the wall. Generally, rough sandpaper is used for preliminary grinding first, and then fine sandpaper is used for fine grinding. Pay even attention when polishing to avoid polishing marks.

Finally, the wall decoration. After the previous treatment, the wall can be decorated, such as painting latex paint and pasting wallpaper. When painting latex paint, we should pay attention to selecting products with good quality and high environmental protection performance, and make deployment and construction according to the requirements of the manual. When pasting wallpaper, pay attention to the splicing and alignment of wallpaper to avoid problems such as empty drum and edge warping.

In the process of dealing with the blank wall, there are also some matters needing attention. When treating at the grass-roots level, it is necessary to ensure that the wall is completely dry before the next step of construction, otherwise it will affect the adhesion and drying speed of subsequent materials, and even lead to problems such as moldy and falling off the wall. In the process of wall leveling, it is necessary to control the proportion and coating thickness of cement mortar and putty powder to avoid cracking and hollowing. When sanding, you should pay attention to protective measures, such as wearing masks and gloves, so as to avoid inhaling dust and causing harm to your body. In the stage of wall decoration, we should pay attention to the temperature and humidity of the construction environment, and avoid the construction in the environment of high temperature, high humidity or low temperature, so as not to affect the decoration effect.

The following is a simple comparison table for you to understand the main points of different processing stages:

Through the above methods and precautions, I believe you can handle the blank wall to achieve the ideal effect and add a beauty and comfort to your home environment.

　　CCTV News:Recently, Ms. Zhang, a consumer in Beijing, bought low-priced postage goods in two stores of an e-commerce platform. She can’t help but wonder: How do individual travelers send a courier to 10 yuan or so, and how do businesses guarantee such low-priced goods?

　　Merchants would rather lose money in marketing and attract consumers.

　　According to a reporter’s investigation, low-priced package goods are very common in major e-commerce platforms, especially "9.9 yuan package" has become a word that consumers are accustomed to. But questions like Ms. Zhang’s are common among consumers.

　　Ms. Zhang told reporters that she asked the owners of two stores afterwards. Both shopkeepers said that the low-cost package was to attract consumers and sell at a loss.

　　 Marketing at a loss, don’t businesses make money?

　　Yao Jianfang, an analyst at the E-commerce Research Center, told reporters that the fundamental reason for the existence of low-priced postal goods is that businesses are profitable. Online shop operation flow is king, and low-cost postage can be used as a good drainage method, which is lower in cost than other means of burning money. Compared with violations such as brushing a bill, it is better to post some money for promotion.

　　The reporter searched for "garbage bags" on an e-commerce platform. According to the comprehensive ranking, the turnover of garbage bags below 10 yuan and including postage was as high as 200,000 to 300,000. Of course, there are also stores with slightly higher prices and no postage.

　　Even if it is a low-cost package, not all businesses are making money at a loss.

　　Yao Jianfang explained that in order to make money by low-cost package, it is necessary to have low-cost purchase channels and control purchase costs.

　　Long-term cooperation with courier companies to keep the courier cost to a minimum. The sum of the prices of these two parts is controlled below the sales price. If the goods are sold enough and even become explosive, the profit will be considerable.

　　How does the courier company make money?

　　A courier practitioner said that for customers with large orders, they adopt a monthly settlement method, and the price is different from the usual zero order. Pricing varies from province to province. The nearest place within 3kg is generally 4 yuan, and the price of some courier companies may be lower. Some express outlets increase their business volume by collecting a lot of money, which can not only make small profits but also expand their right to speak.

　　Mr. Huang of Beijing bought a pair of scissors for 6 yuan postage online. Afterwards, he found on a wholesale website that the lowest wholesale price of this pair of scissors can be around 2 yuan. The reporter noticed that the commodity link of this pair of scissors shows that its monthly sales volume is 15,000, and the total sales volume has exceeded 100,000. Even if a pair of scissors can’t earn 1 yuan money, the total profit can be counted.

　　Have you inadvertently walked into the business routine?

　　In addition to small profits but quick turnover, low-cost postal merchants have other ways to make money. Common operations are:

　　Selling low-priced postal goods is accompanied by advertisements for other goods in the store, and making money through the sales of other goods;

　　After attracting attention and brushing traffic through low-cost postage, replace the goods with high-priced goods or raise prices step by step;

　　Set multiple specifications labels under a link, and consumers will find multiple styles and specifications when they enter the link through low-priced goods, thus improving the exposure rate of high-priced goods;

　　Even some merchants don’t tell consumers the specific content of low-priced goods in the name of "blessing bags", but consumers find that they are inferior goods after receiving the goods. (This article Source: Workers Daily)

"Long life" is everyone’s wish, although not everyone can achieve it, but even if you can’t live long, you must live a healthy and healthy life.

With the improvement of living standards and people’s attention to health preservation, more and more people doubt that they are sub-healthy, so what about their health?

Xiaobian has compiled some characteristics of a healthy body, which can be compared. If you are satisfied more, then you will be healthier.

01

The wound is repaired quickly.

If the wound heals easily, it means that the blood coagulation ability, white blood cell sterilization ability and blood vessel health are all good. If a minor wound or minor burn takes a long time to heal, or slight pressure causes unexplained skin bruising, see a doctor.

02

Stable weight

Chinese medicine believes that fat people have more qi deficiency and more phlegm and dampness; Thin people have more yin deficiency and more fire. At this time, as long as it is not too fat or too thin, there is no need to deliberately lose weight or gain weight. The weight has remained stable, indicating that the body is very healthy.

If the weight changes suddenly, it means unhealthy and needs special attention!

03

A full night’s sleep

A healthy sleep state is that you have fewer dreams, get up less at night, and sleep until dawn. This is the healthiest state of sleep.

The quality of sleep is poor. I get up several times every night. Although I sleep for a long time in MUBI at night, my brain and organs really get a rest for a very short time, which is also a sign of my unhealthy body.

04

Nails are ruddy and without edges.

Nails are directly related to the viscera and meridians of the human body, and the healthy changes of the human body can be fully reflected through nails. The health of nails is related to the nutritional status of the body, the intake of vitamins and the stability of detoxification. The ruddy nails without edges indicate that the blood is sufficient and there is no calcium deficiency, which also indicates that the endocrine is normal.

And the liver is the main rib, and the nail is a part of the tendon. The health of the nail will also reflect the health of the liver. The liver is known as the "general of the human body" and plays an important role in the health of the human body. The liver is good and everything is fine!

05

Hair moist

Chinese medicine believes that "kidney, its China is in the hair" and "hair is in addition to blood". The growth, shedding, moistening and withering of hair depend not only on the nourishment of essence in the kidney, but also on the nourishment of blood. The healthier a person is, the fuller the blood is, and the hair will naturally be moist. On the contrary, when the essence and blood are deficient, the hair tends to turn white and fall off.

06

Less meat on the stomach

The belly fat that can’t be thrown away is a headache for many people. Abdominal obesity is not a trivial matter, which not only affects the beauty of body shape, but also is a signal of pre-illness state-causing hypertension, angina pectoris, myocardial infarction, diabetes and so on.

Studies have shown that the risk of death faced by women with abdominal obesity is 20% higher than that of ordinary people. Usually pay more attention to the waist circumference, which is less than 90cm for men and 85cm； for women; Don’t eat too late for dinner, or you’ll get fat. Exercise more and control your weight.

07

pleasant personality

Cheerful personality will make the body in a pleasant state, and the function and state of the body are at the best. The enzyme activity of the body is also in a good state, so it is healthier and longer.

08

Defecation once or twice a day.

Stool obstruction is one of the important criteria to test the health of digestive and excretory systems. Always can’t solve the stool, stool accumulation, will continue to produce toxins, resulting in gastrointestinal dysfunction, endocrine disorders, mental stress and other problems.

A cup of boiled water in the morning can promote excretion, prevent constipation, dilute blood and promote blood circulation.

The financial business has a very high "gold content" among foreign automobile companies. For example, there are only two major business segments: "manufacturing+finance", and the profits from the financial segment also exceed 20% of the total profits of the public. The financial sector made a greater contribution to GM. Before the bankruptcy of GM, the profit from financial business accounted for more than 60%.

Gu Feng was given the "task" by Chen Hong, chairman of SAIC, to increase the profit of SAIC’s financial business from about 8% at present to 15%-20%. In order to achieve the goal smoothly, SAIC Finance Department was established, and Gu Feng was appointed as the general manager. At the same time, Wu Heng, deputy general manager of the Finance Department, and more than a dozen middle and senior cadres of SAIC were appointed.

Now, with Gu Feng’s departure, whether SAIC’s huge plan in financial business can continue to be implemented remains to be further verified.

Following the departure of Zhang Hailiang, former vice-president of SAIC, and joining LeTV in March this year, the senior management team of SAIC changed again.

A few days ago, 21st century business herald reporter learned that Gu Feng, CFO of SAIC (equivalent to vice president of SAIC), has submitted his resignation report, which is currently awaiting the approval of Shanghai SASAC.

Together with Zhang Hailiang, who left in March this year, this is the second vice president-level executive of SAIC in half a year.

Like Zhang Hailiang, Gu Feng was born after 70, and his career was in the prime of his life. People who are familiar with him are very appreciative of his professional ability and personality. In addition, like Zhang Hailiang in charge of SAIC’s service and trade sector, Gu Feng is also responsible for the transformation of SAIC. In the first half of this year, SAIC has established a financial division, with Gu Feng as the general manager.

After the establishment of the financial business department, Chen Hong, chairman of SAIC, hopes that the financial business profit will now account for about 8% of SAIC’s total profit and rise to 15%-20% in the future. This is also an important symbol of SAIC’s transformation from a traditional automobile manufacturing industry to a comprehensive company that provides comprehensive services to consumers, and will directly affect SAIC’s market value promotion plan, which Gu Feng has also made before. With Gu Feng’s "departure", whether Chen Hong’s transformation plan can be smoothly promoted is also facing a test.

Salary limit must be an excuse.

Some people think that Gu Feng’s resignation was due to "salary restriction". SAIC began to implement the salary limit system in the second half of last year, and the annual salary of municipal cadres has been greatly adjusted.

Generally, the level of vice-president is deputy bureau level. According to the standard of city management cadres, the annual salary is only 600,000, and Gu Feng is one of them. There are more than 1,000 people in SAIC with an annual salary of over one million, which also means that as the vice presidents of SAIC, Gu Feng, Zhang Hailiang and others have an annual salary less than that of an engineer. Prior to this, in 2015, the annual salary of the vice presidents of SAIC Group exceeded one million.

Then compare other companies in the automobile industry horizontally. Generally, private enterprises are native to vice-president professional managers with an annual salary of at least one million, and there are not a few imported talents with an annual salary of more than two million. In 2015, President and Executive Director Gui Shengyue had the highest annual salary, reaching 8.646 million; Executive Director Hong Shaolun, with an annual salary of 7.353 million yuan; Wei Jianjun, the chairman, ranked third with a salary of 5,692,400 yuan.

Even so, a person familiar with Gu Feng told reporters: "It must be an excuse to say that Gu Feng left because of salary restrictions."

Gu Feng, born in 1972, graduated from Shanghai University of Finance and Economics with a doctorate in management and a professor-level senior accountant.

As a trained financial man, if he valued his income, he didn’t need to stay in SAIC for a long time. As a traditional manufacturing industry, the annual salary of SAIC executives is only 2 million yuan, which is really insignificant compared with the financial industry.

According to the average wage of urban employees in 2015 released by the National Bureau of Statistics in May this year, the financial industry is still the industry with the highest income, and the annual salary of financial executives is relatively common.

Gu Feng, who could have entered the hottest financial industry naturally, dedicated his career of nearly 20 years after graduation to SAIC.

Gu Feng, who joined SAIC in 1997, participated in the establishment of Shanghai General Financial System. In 2001, after being transferred to SAIC, he led and participated in SAIC’s overall restructuring and listing in three places in 2004 (Shanghai, Hong Kong and new york, but failed to be listed in the end due to various reasons). In 2016, he led SAIC’s whole vehicle business to be injected into the listed company 600104 (the first case in Shanghai and Shenzhen), and led the acquisition of SAIC in 2007. At the same time, using the capital market platform to actively explore the financing channels of SAIC, during his tenure, he raised nearly 40 billion yuan through financial products such as separate transactions and convertible bonds, private placement and medium-term notes, and finally took the lead in setting up the first 20 billion standby syndicated loan in SAIC’s history. The scope of use of syndicated loans has opened up a new direction for standby syndicated loans.

As the chief financial officer in charge of the company’s financial power, Gu Feng also devoted a lot of energy to independent brands, including how to give more support to independent brands from financial resources, how to formulate more reasonable financial processes and systems for independent brands, and how to make independent brands develop more healthily.

At the same time, SAIC has been acquiring and merging its own brands in recent years, and the financial team led by Gu Feng has been actively exploring mergers and acquisitions with the Group, making a strict risk assessment from the financial point of view, and evaluating the long-term value of the acquired fields and whether they meet the company’s future strategic needs and value-added, so as to promote SAIC’s value investment in emerging technology fields.

During his career of nearly 20 years, Gu Feng has served as the deputy manager of the finance department of Shanghai Automotive Industry (Group) Corporation, the deputy manager of the finance department of Shanghai Automotive Group Co., Ltd., the executive director of the capital operation department, the financial controller and the executive director of the capital operation department. Along the way, he is currently CFO of SAIC, general manager of Shanghai Automotive Hong Kong Investment Co., Ltd., general manager of Shanghai Automotive Group Investment Management Co., Ltd. and general manager of SAIC Finance Division.

Elephant turns to PK new platform and goes into battle lightly.

Where to go after SAIC left? Gu Feng himself has not yet announced it. "I want to have a rest first." Gu Feng said.

People who are familiar with Gu Feng speculate that he should enter a new automobile enterprise or a transformation franchise company to engage in his financial "old line".

"With its personal ability and strength, it is possible to make a leap on a new platform and a new starting point." People familiar with Gu Feng think.

In fact, this time coincides with the transformation of SAIC. Under the leadership of Chen Hong, SAIC is actively seeking transformation. Chen Hong integrated SAIC’s business into four sectors: vehicle, parts, automobile service trade and finance.

However, after all, the elephant turns around. For a behemoth like SAIC, any small change means that it may cost a lot. This is also the reason why many large international companies prefer to be conservative rather than innovative.

For SAIC executives, in the traditional manufacturing industry, they will also encounter the ceiling of career development. For example, for Gu Feng, there is almost no room for CFO to move up, unless he leaves SAIC and enters government departments. For example, Ding Lei, the former vice president of SAIC, left the top official of SAIC to be the deputy head of Pudong New Area, but eventually jumped out of the "circle" and joined LeTV with Zhang Hailiang.

On the contrary, the outside world is wonderful. For example, Zhang Hailiang and Ding Lei, who have left SAIC, have successively joined LeTV and become their executives responsible for global business and China business; For Gu Feng, after jumping out of SAIC, it has a wider range of choices. Like Ding Lei, Zhang Hailiang, it can join a new automobile company and enter the financial industry. The financial industry is mostly international, and for Gu Feng, it has more opportunities to display its talents.

Chen Hong’s transformation business faces challenges.

However, Gu Feng’s departure can only be described as "pity" for SAIC.

SAIC is at the critical stage of improving market value management. After taking over from Hu Maoyuan as the chairman of SAIC in August 2014, Chen Hong was questioned by investors at several shareholders’ meetings of SAIC: SAIC’s financial situation is very healthy, and it was called the "most valuable investment" target of A shares by investors, but SAIC’s share price is not high.

Improving market value management has also been written into Chen Hong’s work agenda. In August last year, Chen Hong revealed that SAIC has added the company’s market value management function and investor relations maintenance work in the office of the board of directors.

At the same time, SAIC has implemented SAIC’s transformation strategy through a series of innovative business expansion. According to Chen Hong’s plan, SAIC will accelerate from a traditional enterprise mainly relying on manufacturing to a comprehensive supplier providing consumers with all-round products and services, and strive to become a world-famous automobile company with global layout, transnational operation, international competitiveness and brand influence.

The "task" given by Chen Hong to Gu Feng is to increase the profit of SAIC’s financial business from the current 8% to 15%-20%. In order to achieve the goal smoothly, SAIC Finance Department was established, and Gu Feng was appointed as the general manager. At the same time, Wu Heng, deputy general manager of the Finance Department, and more than a dozen middle and senior cadres of SAIC were appointed.

The financial business has a very high "gold content" among foreign automobile companies. For example, Volkswagen’s business sector has only two large pieces of "manufacturing+finance", and the profit from the financial sector also exceeds 20% of the total profit of Volkswagen. The financial sector made a greater contribution to GM. Before the bankruptcy of GM, the profit from financial business accounted for more than 60%.

After the establishment of the Finance Division, Gu Feng once revealed ambitiously that the future SAIC Finance Division mainly involves four major functions. First, SAIC will integrate and re-plan the businesses of SAIC Finance Company, SAIC General Finance Company, SAIC Equity Investment and Insurance Company under the Finance Division, with the purpose of linking the financial business with SAIC’s industry, so that the financial business can serve the industry, such as launching the business of car owners’ wealth management and car owners’ balance treasure. Even, the financial department may expand SAIC’s financial business by acquiring banks or insurance companies.

Second, after the establishment of the Financial Division, the financial business of SAIC will be centrally managed. Formulate KPI performance appraisal indicators suitable for financial business. Thirdly, SAIC Finance Division will also have the function of investment bank, and make mergers and acquisitions or acquire technologies through the leverage effect of financial business, so as to enlarge and strengthen the business sector. The fourth is to further enhance SAIC’s asset allocation capability.

Now, with Gu Feng’s departure, whether SAIC’s huge plan in financial business can continue to be implemented remains to be further verified.

　WeChat official account News of CBN WeChat, the critical moment of COVID-19 epidemic prevention and control, a paper published in the New England Journal of Medicine, pushed the China Center for Disease Control and Prevention (hereinafter referred to as "China CDC") to the forefront.

The reason is that, according to this paper, research shows that interpersonal communication has occurred between close contacts since mid-December 2019. In addition, from January 1 to January 11, a total of 7 medical staff were infected. But at this time, the public knew nothing about it.

Should scientists publish papers first or prevent them first? The focus of controversy comes from this. On the morning of January 31st, CBN reporter interviewed Gao Fu, a member of the National Health Commission high-level expert group and director of China CDC. He is the co-author of the above paper.

"This is a retrospective analysis! In mid-December, I still don’t know what the disease is, and the pathogen is unclear. It is the inference of investigating more than 400 cases of epidemiology! Onset’s days are all speculation, which everyone didn’t understand! Mix epidemiological investigation with clinical diagnosis. " Gao Fu told CBN.

Gao Fu also said that retrospective investigation is one of the responsibilities of CDC, to find the culprit, retrospective investigation, and guide future prevention and control. "Our prevention and control has never stopped, and everyone has not slept for a month."

This is a retrospective analysis.

This paper, published on January 29th, US time, was led by China CDC, including professionals from Hubei CDC and Hong Kong University. Correspondents of the study include Feng Zijian, deputy director of China CDC, and Yang Bo, director of Hubei CDC. Co-authors also include Gao Fu.

In this paper, the investigation team analyzed the reported 425 laboratory-confirmed cases as of January 22, 2020. Analysis shows that among the first 425 confirmed patients, the median age is 59 years old and the male is 56%. Most cases (55%) occurred before January 1, 2020 were related to the seafood wholesale market in South China, and the subsequent cases were 8.6%. The average incubation period was 5.2 days, and the 95th percentile of the distribution was 12.5 days. In the early stage, the scale of epidemic cases doubled every 7.4 days, the average continuous interval of infection was 7.5 days, and the number of basic infections (R0) was estimated to be 2.2.

According to this information, the paper said that there is evidence that interpersonal communication has occurred between close contacts since mid-December 2019.

This paper reveals more information about the epidemic situation in COVID-19, which has aroused widespread doubts.

On January 31st, China CDC published an article entitled "Notes of China Center for Disease Control and Prevention on Publishing Articles in the New England Journal of Medicine". The article stated that the paper was based on a retrospective analysis of 425 confirmed cases (including 15 medical staff) reported as of January 23rd, 2020, and all cases were published to the public before the paper was written. The 15 cases of medical staff infection mentioned in the paper were announced to the public by Academician Zhong Nanshan, the leader of the high-level expert group in National Health Commission, on the evening of January 20th and the Wuhan Health and Health Commission in the early morning of January 21st.

The viewpoint that "interpersonal communication occurred among close contacts in December 2019" put forward in this paper is a retrospective inference based on the epidemiological investigation data of 425 cases.

The article also said that publishing the survey results in academic journals in time will help professional colleagues at home and abroad to understand the characteristics of the disease in time, jointly evaluate and judge the epidemic situation, and improve the prevention and control strategies.

However, this article did not respond, when did China CDC come to the judgment that "interpersonal communication occurred among close contacts in December 2019".

For infectious epidemiology, retrospective study is indeed extremely important. Without retrospective study, it is impossible to understand the incidence of infectious diseases more clearly and then formulate prevention and control strategies for infectious diseases. Therefore, after the outbreak of an infectious disease and case diagnosis, epidemiological investigators will appear first.

An expert in epidemic virology also told reporters that retrospective research is the basic work of infectious diseases and must be carried out according to existing cases. Without cases, no one can observe what the development path of this virus is.

"In fact, the data of 425 cases is not enough to show the characteristics of the new virus. It can only explain the situation in the past and (425 cases) at that time. How to develop in the future needs to continue to be observed." The above-mentioned experts in epidemic virology said.

For example, China CDC stated that these cases were previously confirmed cases, and the research team used these public data to start a retrospective analysis.

How to carry out retrospective analysis?

According to this paper, the earliest cases in COVID-19 were identified through the surveillance mechanism of pneumonia with unknown etiology.

In order to identify pneumonia cases and strive to improve the sensitivity of early detection, the research team developed a tailor-made monitoring program to identify potential cases on January 3, 2020.

The initial working case definition for suspicious COVID-19 is based on the case definition of SARS and Middle East Respiratory Syndrome (MERS). After obtaining new information about confirmed cases, the epidemiological criteria for defining suspicious cases were updated on January 18, 2020.

Once suspicious cases are found, a joint team composed of China CDC, provincial CDC, local CDC and county CDC will be notified to carry out detailed on-site investigation and collect respiratory tract samples, which will be tested in the Center for Viral Disease Prevention and Control of China CDC.

A joint team composed of staff from China CDC and local CDC also conducted detailed field investigations on all suspected and confirmed cases. They collected epidemiological data through interviews with infected people, relatives, close contacts and medical staff, so as to determine the contact history of patients two weeks before onset, including the date, frequency, frequency and mode of contact with wild animals, especially the wild animals available in the South China Seafood Market in Wuhan. In addition, the researchers also collected information about exposure to any relevant environment and contact with others with similar symptoms.

All the epidemiological information collected in the survey, including contact history, timetable and the identity of close contacts, were cross-checked.

Through this path, the research team obtained the epidemiological information of 425 cases.

The basic infection number is about 2.2.

The importance of retrospective analysis of infectious diseases lies in seeing clearly the laws of infectious diseases, and only by seeing clearly the enemy can we make better prevention and control.

In addition to the above-mentioned questioned contents, what other noteworthy information does this paper reveal?

In this paper, the researchers estimate the growth rate of the epidemic by analyzing the data of cases between December 10, 2019 and January 4, 2020.

According to the paper, limited to the data before January 4th, it is estimated that the basic number of infections in COVID-19 is about 2.2, which means that each patient spreads the infection to 2.2 other people on average. As far as COVID-19 is concerned, the paper said that the control challenges include the obvious existence of many mild infections and the limited resources to isolate cases and close contacts.

However, due to the increased awareness of the epidemic situation and the increased availability and utilization rate of inspections in recent weeks, the confirmed infection rate will increase.

A chart used in this article shows that after January 11th, the number of cases decreased. However, the paper also said that it is probably due to the uncertainty of recent cases and the delay in identification and reporting, rather than the real turning point of incidence.

Considering that the availability and usage of test kits will increase with the passage of time, the paper said that extra care should be taken in explaining the growth rate of cases in January.

In short, the research results also show that in the early stage, the case size doubled every 7.4 days. The average continuous interval is 7.5 days.

The paper also reminds that the urgent next step includes determining the most effective control measures to reduce the spread within the community. With a better understanding of epidemiological characteristics and the dynamic mechanism of cases, it is also necessary to improve the definition of work cases. At the same time, it is also necessary to continue to monitor cases to find any changes in epidemiology, such as infections among young people or medical workers.
