Recently, the international gold spot and futures market prices have hit record highs, which has aroused widespread concern in the market. On December 4th, new york gold futures and London spot gold both broke through the $2,100 mark per ounce, with new york gold futures hitting a record high of $2,152.3 per ounce and London spot gold hitting a record high of $2,144.68 per ounce.

However, in the following trading days, the price of gold showed a high downward trend, and the upward price appeared to be powerless. As of the close of the 7th, the most active February 2024 gold futures price in the New York Mercantile Exchange gold futures market fell by $1.5 to close at $2,046.4 per ounce.

Some analysts said that considering that the current inflation in the United States is still resilient, it is difficult to start the interest rate cut cycle in the first quarter of next year, and the US bond issuance in the first quarter of next year is still at a historical high, thus limiting the downside of the US bond interest rate, and the gold price may face callback pressure in the short term.

"In the short term, we are still cautious." Highfill, chief investment director of UBS Global Wealth Management, explained to the First Financial Reporter that the market’s bet on the Fed’s interest rate cut next year may be over-optimistic, and the hedging premium brought by geopolitical risks may be further digested. In addition, the further rise of gold may need to see the continuous net inflow of funds into gold exchange-traded funds (ETFs).

The medium-term prospects are still optimistic.

Nevertheless, Highfill is optimistic about the medium-term prospects of gold. Looking forward to 2024, UBS believes that the gold price will look at $2,250, and the Fed’s narrative will turn to easing and cutting interest rates, which will further open up the upside of gold prices.

"The trend of gold after the Palestinian-Israeli conflict supports our view that gold is an important asset for medium and long-term capital allocation. We believe that in a balanced investment portfolio, the proportion of gold allocation in the middle single digits is appropriate." Highfill thinks that when the price of gold falls below $2,000, it is an opportunity to further invest in gold.

In November, the trend of international gold price first suppressed and then rose. At the beginning of the month, the market’s risk aversion to the Palestinian-Israeli conflict gradually cooled down, and the safe-haven premium of gold began to ebb. Even in the context of the downward fluctuation of the US dollar index, the price of gold still showed a high downward trend. After the safe-haven premium was digested, the downward trend of the US dollar index and US bond interest rates pushed up the price of gold as the inflationary pressure in the United States in October eased more than expected and the superimposed economic momentum slowed down.

On November 14th, data released by the US Department of Labor showed that inflation cooled down more than expected. In October, the consumer price index (CPI) in the United States dropped from 3.7% in the previous month to 3.2%, which was lower than the market expectation of 3.3%. The chain was flat, the smallest increase since July 2022. At the same time, the core CPI excluding food and energy decreased from 4.1% last month to 4.0%, lower than the market’s previous forecast of 4.1%; The chain rose by 0.2%, the smallest increase since July this year.

In October, housing fell to 0.3% month-on-month and 6.7% year-on-year, which is still at a high level. From the historical experience, the rent price involved in housing CPI is often sticky, lagging behind the house price for one to two years. On November 29th, S&P CoreLogic Case-Shiller national house price index data showed that house prices in 20 cities in the United States rose by 3.9% year-on-year in September, and it has been 19 months since the peak in April 2022.

Analysts said that with the Fed raising interest rates and shrinking the table, the 30-year mortgage interest rate in the United States soared to over 7% at the end of October last year, and rose to over 7.0% again in August this year. Under the pressure of high interest rates, the housing breakdown is expected to continue to improve in the fourth quarter, which will further ease inflationary pressures.

The resilience of the labor market is the basis for American residents to maintain their spending power, and it is also the key to the resilience of inflation. Recently, a number of data show that the US job market has obviously cooled down. On December 6th, the American private sector (ADP) employment report, known as "small non-agricultural", showed that the number of new jobs in ADP was lower than expected for four consecutive months in November, and the number of new jobs was revised down in October, while the wage growth rate in November hit a new low in more than two years.

All these have enhanced investors’ expectations for the Fed to cut interest rates next year. In addition, the tone of Fed officials’ speeches has eased recently. In his latest speech, Waller, a Fed governor who has always been "hawkish", mentioned the possibility of starting to cut interest rates after inflation continues to return, which triggered the market’s pricing of early interest rate cuts, driving the real interest rate and the US dollar to fall back at the same time, which boosted the gold price.

Nicky Shiels, metal strategist at MKS PAMP, said: "Gold has become a barometer reflecting the Fed’s interest rate cut expectations and market risk aversion."

Regarding the reasons for the recent rise in gold prices, analysts also believe that there are factors such as the wave of gold purchases by the central bank and the safe-haven premium brought by the geopolitical situation.

Aakash Doshi, head of commodity research in the Americas at Citigroup, said that despite the rapid rise in interest rates, the purchase by central banks was the key reason why the value of gold remained strong last year.

Is there more potential for silver prices to rise?

However, unlike the central bank’s continuous gold purchase fever, the global gold ETF has flowed out of 189 tons since the beginning of the year, and it has shown a net outflow trend for six consecutive quarters, which of course caused some investors’ concerns.

At the same time, analysts said that as the anchor of short-term pricing of gold prices, the US bond interest rate currently lacks the conditions for a downward trend. Therefore, there is a high probability that the price of gold will remain high in the short term.

Suki Cooper, an analyst at Standard Chartered Bank, said: "In the past two years, the gold market has always rushed to the monetary policy shift.Although we expect the Fed’s next move will be to cut interest rates, we don’t think it will happen soon. "

In contrast, analysts believe that,The price of silver is still seriously undervalued. With the improvement of risk appetite, silver is more elastic as a "shadow of gold" than gold and silver. And historically, it has outperformed gold in the gold bull market.

On the 7th, the price of silver futures for delivery in March 2024 closed down 16.9 cents to US$ 24.059 per ounce, and the ratio of gold to silver was 85:1, which was still at a high level in history. Looking back on the trend of gold-silver ratio in recent 50 years,The duration of high gold-silver ratio is limited, and most of the time fluctuates between 40:1 and 60:1.In 2011, the ratio fell to 30:1, and in 1979 it fell below 20:1.

Peter Schiff, chief economist of Euro Pacific Asset Management, said that at the current price, silver is really cheap, the price of silver is obviously undervalued, and the market supply and demand deficit is serious. "I think silver is especially in a good opportunity for allocation, because gold is at a record high, and silver must double to hit a record high. This shows that silver is very cheap. " He said.

Indeed, from the perspective of supply and demand dynamics, according to the latest forecast of Oxford Economic Research Institute, the demand for silver in industrial applications, jewelry production and silverware manufacturing is expected to nearly double in the next 10 years.

In 2022, the demand for silver set a record in all categories. At the same time, the output decreased slightly by 0.6% to 822.4 million ounces, resulting in a market deficit of 237.7 million ounces last year, which is the second consecutive year. The Silver Research Institute predicts that the demand will reach 1.17 billion ounces this year, while the estimated supply is 1.02 billion ounces. Although this will reduce the gap to 142.1 million ounces, it will still be the second largest deficit in more than 20 years.

The draft of "No, No, No, No, No, No, No, No, No, No, No, No, No, No,No." nbsp; What are you talking about? /a>

With the rise of the national tide, under the empowerment of the Internet, antiques and cultural relics have not only successfully "broken the circle" through the channel of e-commerce, but also moved from the attention of a few people to the public’s field of vision, and even developed into the next e-commerce category under the wave of live broadcast, creating a literary and entertainment e-commerce "unicorn" with annual sales of 43 billion yuan-micropattern.

Recently, CCTV financial reporters conducted an investigation on the micro-pat hall, and found that buyers often photographed celebrity calligraphy and paintings and even wenwan jewelry at very low prices, and these collections were equipped with appraisal certificates issued by appraisal institutions. The survey found that the goods photographed by consumers at the "missing price" were different from the introduction after identification, which made it difficult for consumers to defend their rights. Although the payment has been refunded, the appraisal fee has to be borne by the consumers themselves. Even, some merchants refused to accept the fake, and the platform said that there was nothing they could do.

In addition to media exposure, the online consumer dispute mediation platform "Dianv Bao" has also received many cases in which users suspect that counterfeit goods choose to return and fall into the dilemma of rights protection, mainly involving platforms such as micro-pat hall, playing with things, and daily treasure. Among them, selling fake goods, defective goods, wrong goods, difficult refund, delayed delivery, unreasonable deduction of store deposits and after-sales problems have become hot complaints.

Chaos 1

Commodity appraisal is "in name only", and it is difficult to guarantee 100% authenticity.

According to CCTV’s financial report, the reporter photographed 380 yuan’s bloodstone seal, 228 yuan Tian Huangshi inkstone and 192 yuan Tian Huangshi ornaments in a shop called "Wu Nian Ming Xuan". However, after testing by Beijing Peking University Gemological Appraisal Center, the article with the nominal bloodstone is actually chlorite imitating bloodstone, the inkstone with the nominal Tian Huangshi is actually dyed chlorite, and the ornaments with the nominal Tian Huangshi are actually dyed talc.

On October 6, 2020, Mr. Pan bought the third set of RMB in the "Micro-Pat Hall" of Hangzhou Micro-Pat Hall Cultural and Creative Co., Ltd., which has been identified as all counterfeit, amounting to 1380 yuan. The store is fraudulent, and the platform is only willing to refund without making any compensation.

In this regard, Meng Huixin, an analyst at the Legal Rights Department of the Network Economic and Social E-Commerce Research Center, said that at present, the supervision based on wenwan e-commerce is relatively loose, and the platform review system is not perfect, so there are frequent incidents of selling fakes, selling fakes and shoddy. Especially for wenwan items, although the platform provides testing and identification services, there are still inaccurate results that cause consumers to receive fake and inferior commodities, which makes it difficult to protect their rights.

Chaos 2

The goods are not in the right slot, and the user is caught in the "refund difficulty"

On December 12, 2019, Mr. Xun of Jilin Province purchased the brave hand-made pieces through the merchant of "Professional Hetian Jade Finished Product Management" on the platform of "playing with things". The merchant promised that the goods were the only seeds of Hetian jade in Xinjiang, which were the works of Zhang Baoguo, a national jade carving master, and supported the national re-inspection. After receiving the goods, Mr. Xun felt that the goods did not match the description of the merchants. After the goods were sent for identification, they were proved to be non-Hetian jade in Xinjiang.

"The goods delivered by merchants do not match the description, which is actually a common phenomenon of’ goods are not right’ in online shopping." In this regard, Meng Huixin mentioned that if consumers purchase the goods clearly described by the merchants and complete the payment, then the merchants should complete the delivery according to the agreement of both parties. If the goods delivered by the merchants are inconsistent with the actual situation, or even other problems occur, they should give consumers the after-sales service they deserve, instead of making consumers fall into the dilemma of "difficult rights protection".

Meng Huixin further analyzed that in view of the difficulty in returning goods, many e-commerce platforms have formulated rules to limit consumers’ returns, such as refusing to return goods for 7 days without reason, deducting handling fees, service fees and appraisal fees, so as to reduce the costs and risks that the platform should bear as an operator. Some merchants even delay the return time of goods by refusing to return parcels, and give consumers a refund, which is unreasonable for consumers.

Chaos 3

The platform privately deducts the seller’s deposit.

Mr. Pei of Shanxi Province auctioned porcelain antiques live on the micro-auction hall trading platform, and a blue-and-white porcelain powder box of Kangxi period in Qing Dynasty returned from abroad was photographed by customers. On October 3, 2020, after receiving the goods, the buyer thought it was an imitation, applied to the platform for "refund only, no return", and then asked to identify the goods, which immediately received a positive response from the micro-pat hall.

On October 22nd, the micro-pat hall sent Mr. Pei the final appraisal and handling results: selling counterfeit imitations, closing the store for 14 days, and imposing a fine of 3,000 yuan, as well as the appraisal fee of 150 yuan and the inspection fee of 25 yuan; And told the buyer that the blue-and-white porcelain with a transaction price of 1552 yuan "does not need to be returned". Mr. Pei complained that the so-called "Jian Zhen Pavilion" of the micro-pat hall platform did not have the qualification to identify ceramic porcelain or did not have this business. After fooling and deceiving the seller in such a perfunctory way, the platform was fined several thousand yuan, the buyer got an antique for nothing, and the seller lost both money and goods.

Suggestion > > >

Standardization is the "foothold" of wenwan e-commerce

Meng Huixin said that in the era when everything can be e-commerce, the "stall economy" that used to exist in the antique market has also become a "cloud tour" literary play, but the inherent ills such as fishy eyes and fake goods still exist.

Since wenwan e-commerce is mostly carried out in three links: "live broadcast+auction+appraisal", it is easy for merchants to "fish in troubled waters" to raise prices, so that consumers who sincerely buy them mistakenly think that they are "missing", but in fact they have already secretly marked the price.

At the same time, counterfeit goods have also given birth to the demand for identification. The identification itself is to distinguish between true and false, but the opposite result has appeared, indicating that the platform is incomplete and irregular in terms of identification standards and appraisers’ qualifications. Therefore, it can be said that standardization is the "foothold" of wenwan e-commerce. "Fake the truth" is still the pain point of the whole wenwan e-commerce. Driven by huge profits, many fake and shoddy goods are mixed in it. Then, for the platform, it needs to spend more cost and technology to realize it, standardize the platform merchants and ensure that the interests of consumers are not infringed.

On the evening of October 6th, Yu Chengdong, managing director of Huawei, CEO of terminal business group and chairman of smart car solutions, talked about the sales of the new M7 in the circle of friends. He said that on October 6, the number of new M7 vehicles was 7,000, and on October 5, it was 3,500, exceeding 10,000 in two days. Since its listing on September 12th, the cumulative order of the new M7 has exceeded 50,000 vehicles. "We are going all out to speed up the mass delivery of high quality." You can feel the joy of Yu Chengdong through the screen.

If, as Yu Chengdong said, the new M7 has ordered more than 50,000 vehicles in less than one month, then this wave of operation really deserves to be taken seriously. However, there is a premise that most orders can be converted into real sales.

Consumers are still hesitant to place an order

At about 10: 30 in the morning of October 10, the reporter went to the Blue Harbor Huawei Experience Store in Chaoyang District, Beijing. Because it is a working day and the time when the shopping mall just opened, the reporter did not see any consumers looking at the car. Store staff introduced that on September 12th, when the new M7 was just launched, there was no car show in the store. A few days later, the exhibition cars were sent to the stores one after another. The passenger flow in Blue Harbor is relatively large, especially there are many customers who come to the store to see cars on weekends, so the order quantity is ok, but the specific data can’t be disclosed. After October 7th, the new rights and interests given by the government decreased by 3,000 yuan compared with before, of which 15,000 yuan’s three-choice-one discount and 12,000 yuan’s interior and exterior decoration options remained unchanged. If you order now, it will take about 4 to 6 weeks to pick up the car.

Near 12 noon, the store in Heshenghui Huawei, Chaoyang District, Beijing was crowded. In 10 minutes, two groups of customers asked about the new M7. Two middle-aged men consulted the product parameters in detail and felt the interior workmanship in the car. They told reporters that because they trusted Huawei brand, they came to learn about the new M7. They are most concerned about the quality and manufacturing technology of vehicle parts. The reason why they didn’t pay the deposit today is that they are not satisfied with the vehicle space. They are going to wait until M9 is listed.

A few minutes later, a young couple stopped in front of the screen in front of the Huawei store, and immediately a staff member came forward to receive them. The couple said that because there are old people and children at home, they are more interested in space and want to choose a six-seat or seven-seat model. They have also seen Ideal L9 and Tengshi D9 recently, and have not yet decided which brand to buy. "We used to drive a fuel car, because the intelligence level of new energy vehicles is generally much higher than that of fuel vehicles, so we will not focus on comparing the differences in intelligence levels of different new energy brands. Because there is a certain mileage anxiety about pure electric vehicles, we want to see extended-range models. " The man said.

The relevant person in charge of Huawei’s Beijing auto business revealed that on October 6, Beijing’s smart car selection business was set to exceed 201 vehicles.

Multiple factors lead to the new M7 becoming a "topic" model.

Mei Songlin, senior analyst of automobile industryIn an interview with the reporter of "China Automotive News", it is believed that the new M7 has benefited from three aspects: First, the successful listing of Huawei Mate 60 Pro mobile phone has branded Huawei as "far ahead" and promoted a new round of Huawei fever; Second, the price is sincere, whether compared with the old model or the main competing products, the new M7 price has a certain price advantage; Third, product upgrades, especially smart cockpit and intelligent driving technology upgrades. Therefore, the listing of the new M7 has achieved "thunder and heavy rain".

Hao Qingfeng, Deputy Secretary-General of china law society Consumer Protection Law Research AssociationThe advantages of the new M7 can be summarized in four aspects. Technically, the new M7 is equipped with Huawei intelligent cockpit HarmonyOS car and ADS high-order automatic driving system, which provides users with intelligent in-car experience, such as voice assistant, navigation, entertainment and other functions, and meets the needs of modern consumers for intelligent cars; As a domestic technology giant, Huawei has strong R&D capability and technical strength, and is one of the representatives of China brand in the international market. In terms of space, the interior space of the new M7 is relatively spacious and comfortable to ride. In terms of power, the new M7 is equipped with an extended-range power system consisting of a 1.5T turbocharger, a four-cylinder range extender and a Huawei drive motor. The maximum power of the range extender is 92kW, and the maximum power of the drive motor is 200kW, which has strong power.

Zhang Xiang, visiting professor of Huanghe Institute of Science and TechnologyIt is pointed out that the new M7 body is reduced by 15mm, which reduces the wind resistance and fuel consumption, and the driving range is longer. In addition, the body power is improved compared with the old version. In addition, its body high-strength steel and aluminum alloy account for 80.6%, and CBS composite material is also introduced to effectively improve the body stiffness and collision safety. The new M7 upgrades the HUAWEI DATS 2.0 dynamic adaptive torque system. By intelligently adjusting the torque, it can effectively reduce the sense of bump and impact, making the vehicle more stable and more comfortable to ride. Moreover, at this stage, the extended-range models are highly accepted by consumers, and the sales volume increases rapidly. At the same time, there are not many competing products. The new M7 chooses this technical route, which also improves the sales growth rate.

Will big sales translate into sales?

On September 12th, the new M7 went on the market. The new car has launched five models, with the price range of 249,800 ~ 329,800 yuan. Among them, the price of the entry-level model dropped by nearly 40,000 yuan, and the price of the six-seat top model was lowered by up to 50,000 yuan compared with the old model. Moreover, when the new car went on the market, the official gave the rights and interests of the first sale period of 33,000 yuan before October 7.

It is reported that in the 25 days from September 12th to October 6th, the daily average number of new cars in the international trade circle is close to 2,000. Some bloggers published an order "Internal Battle Report" for AITO vehicles. As of October 7th (10: 00), the new M7 had a total of 55,506 vehicles.

The so-called big decision is to make sure that the car will be purchased after the arrival of the vehicle by paying the deposit in advance. According to the rules of the brand, it is necessary to pay a deposit of 5,000 yuan online for the new model M7. After the 24-hour "hesitation period" or the "lock order" is selected in advance (the earlier the order is locked, the earlier the production is scheduled), the deposit will not be refunded.

According to public information, in July 2022, three days after the launch of the old model M7, the brand of the company put out posters with orders of more than 60,000 vehicles in three days, but one year after the launch, there was a big gap between its actual sales volume and the number of orders at that time. So, will the new M7′ s grand meeting eventually translate into sales?

Mei Songlin said that as long as it is a real big deal, the default rate is usually very low, unless competing products are willing to pay for the liquidated damages.

Zhang Xiang also believes that the adoption of the big-setting model to collect orders can reduce the proportion of consumers’ remorse to a certain extent, so the proportion of big-setting converted into sales will be higher.

Hao Qingfeng told reporters that when consumers pay a large deposit, they will carefully consider it and be more cautious. The order is only a preliminary decision. It is not excluded that some people will hesitate or go back on their word when they really make a decision. Generally speaking, it is very high to have about 30% of the clients consulted. However, even if a big deal is made, it may not be all done. "The hot booking is just the beginning, and it doesn’t explain all the problems. The real transaction volume only explains the problem. For manufacturers, whether the car can be delivered on time, whether the pre-sales and after-sales services are in place, whether the product quality is passed, and whether the experience of the first batch of users can be guaranteed are all unavoidable challenges. " He said.

Zhong Shi, an auto industry analystFrankly speaking, only the final transaction is the last word, even the "big decision" is not very meaningful.

If the big seller is expected to return to the "poker table"

It is worth noting that the sales of Huawei’s old M7 dropped sharply. From the monthly sales of more than 1,200 vehicles at the beginning of the year to more than 400 vehicles in June. The monthly sales volume of the old M7 has not exceeded 1,000 vehicles for four consecutive months, and the monthly sales volume of the brand has been shrinking to less than 10,000 vehicles.

In this regard, many insiders also expressed their views to reporters. Zhong Shi believes that the problem in the world may stem from consumers’ unclear cognition. The car is produced by Cyrus, and Huawei provides the intelligent selection system, and promotes and sells it in Huawei’s channels, which may cause cognitive disorder to customers. He bluntly said that it is unlikely that the sales of the new M7 will suddenly skyrocket, and the brand image and product sales are done step by step. As an automobile brand, we should do a good job in products in order to win the trust of consumers.

Hao Qingfeng said that both M5 and M7 had weak sales before, and the root cause was that the product strength was insufficient, the internal space was small, the crash test performance was average, and the whole product lacked bright spots.

Hao Qingfeng believes that if the new M7 really sells well, it will have the following effects on the development of the brand: First, enhance the brand influence. The hot booking of the new M7 will generate a good reputation among consumers, enhance consumers’ trust and recognition of the brand, and thus enhance brand influence; Second, increase brand competitiveness. The unique design and excellent performance of the new M7 make it highly competitive in the new energy vehicle market. This kind of competitiveness will promote the position of the brand in the new energy vehicle market and make the brand more competitive; Third, promote brand innovation. In order to meet the changing needs of consumers, the brand must continue to innovate products. This innovation will promote the sustainable development of the brand in the market; Finally, attract more investment. If a brand orders a lot of products, it will attract more investment. This is very important for the long-term development of the brand.

Zhang Xiaorong, Dean of Institute of Deep Science and TechnologyIt is also indicated that if the new M7 can become an explosion, it will bring more profits and market share to the brand in the world and contribute to the long-term development of the brand. In addition, the success of the new M7 will enhance the popularity and reputation of the brand, and provide support for brand image building and market recognition. Successful products will also drive the sales of other products and form a good product line derivative effect.

Mei Songlin pointed out that the problem of poor sales of the old models lies in consumers’ expectations of the new models, because the potential customers knew that the new M7 was going to be listed, and they had already waited for the money to be purchased, so the old products were naturally left aside. If the current big data is reliable, this level of products (large SUVs) can have thousands of big orders every day, which means that Huawei is on the "card table" again and has become another "potential stock" in the new energy vehicle market.

　　CCTV News:The Ministry of Water Resources announced today (September 18th) that the Yellow River Basin has made phased progress in ecological environment improvement and water-saving development since the strategy of ecological protection and high-quality development was put forward two years ago.

　　In terms of strengthening ecological protection, in the past two years, through ecological regulation, the ecological flow of 15 sections of the main stream and 6 tributaries of the Yellow River has all reached the standard, the ecology of key lakes and wetlands has continued to improve, and the wetland area at the estuary has increased by 1627 hectares.

　　In terms of strengthening water management, in the past two years, the water-saving evaluation of planning and construction projects has been comprehensively promoted, and the annual water intake of the project has been reduced by 44.34 million cubic meters. According to statistics, in 2020, the water consumption per 10,000 yuan of GDP, 10,000 yuan of industrial added value and the average irrigation water consumption per mu in the Yellow River Basin will decrease by 3.4%, 9.3% and 8.8% respectively compared with 2019.

CCTV News:Satellite communication, because it has nothing to do with geographical environment and distance, is developing in the military and civilian fields all over the world. European and American countries started in the 1950s. When Sun Chenhua entered the 54th Research Institute of China Electronics Technology Corporation in 1986, China was still decades behind Europe and America in this project.

In the 32 years since he joined the work, Sun Chenhua has experienced the development process of China’s satellite communication from scratch and from weak to strong. She participated in it with a high sense of responsibility, presided over dozens of national and national defense key projects, and won 12 scientific and technological progress awards at or above the provincial and ministerial level (including 2 at the national level), ranking first in 7; In 2011, he was granted special government allowance by the State Council; In 2014, he was selected into the national 100 million talents project and was awarded the title of national young and middle-aged expert with outstanding contributions; He has won more than 10 honors at or above the municipal level, such as the National March 8th Red Flag Bearer, the Provincial May 1st Labor Medal, and the Provincial March 8th Red Flag Bearer. In 2017, he also won the Provincial Award for Outstanding Contribution to Scientific and Technological Innovation. She has trained the top domestic satellite communication team, and made outstanding contributions to the realization of China’s satellite communication from dependent introduction to independent research and development, accelerating the major transformation of China’s creation, promoting the deep integration of military and civilian satellite communication, and promoting the development of strategic emerging industries related to satellite communication between the country and Hebei Province. In 2018, she won the National May 1st Labor Medal.

Fight for 25 years to break the monopoly

When he came to the 54th Institute, Sun Chenhua first undertook the tasks of China’s first CDMA satellite communication system and the first tactical mobile satellite communication system. At that time, advanced technology was blocked by foreign monopoly. CDMA, which relies entirely on independent research and development, has experienced "eight years of anti-Japanese war", and the tactical mobile satellite communication system is even more difficult, with nearly 10 years of efforts before and after. When she was eight months pregnant, she stood up all night to solve the problems in the joint exam, returned to work three months after giving birth, and went on a business trip for more than 40 days when the child was less than one year old … … After more than ten years’ efforts, Sun Chenhua and her research group have broken through many key technologies and cultivated an independent research and development team of the "Professional Department".

She once said, "Many people don’t understand why I work so hard. Actually, it’s not that I don’t want to rest, it’s not that I don’t want to slow down, it’s because I can’t. Opening up a professional direction requires many people to make a lot of efforts, but losing a direction may be just an instant. "

Long-term experience accumulation has also laid the foundation for breaking foreign monopoly. In 2001, Sun Chenhua received a project from a military region and became the executive deputy chief engineer of the project to take charge of the overall work. This project involves a brand-new satellite communication system MF-TDMA. This is also Sun Chenhua’s first contact with TDMA. This technology has been monopolized by foreign countries for a long time, and users designated MF-TDMA system to be imported from foreign countries.

Sun Chenhua spent two months, consulted countless materials, thoroughly studied the relevant principles and data of this system, and completed the integrated application scheme. To be prudent, she asked the foreign company to give a plan. But she was keenly aware that the scheme they gave lacked a device, without which the system could not work normally. However, the foreign agent disagreed with her opinion.

"If you insist that there is no problem, then you have to sign a memorandum with us. If I am proved right later, you have to bear all the expenses of this equipment." Sun Chenhua said confidently.

Later experiments proved that Sun Chenhua was right. It was this "memorandum" that allowed foreign companies to give them 11 sets of equipment for free, each worth about 2,000 US dollars, with a total amount of nearly 200,000 yuan.

Six months after the introduction of equipment, foreign engineers came to the institute to communicate, which surprised him at the scene. "We have been developing this system for more than 20 years, and the system is particularly complicated. It is amazing that you used this system without training!"

In view of the accumulated experience in this project, in 2002, Sun Chenhua made repeated thoughts and made up his mind to develop our own TDMA communication system.

The road to project establishment is not smooth. The overall person in charge told her: "The country has long wanted to participate in this project, but it has been afraid to participate. ‘ Generation star ’ At the time of research and development, someone mentioned this system, but eventually gave up due to technical difficulties. " However, Sun Chenhua was overcome with difficulties. "Although it is difficult, this new system must be mastered in order to develop satellite communication." She organized a team to repeatedly study and demonstrate and repeatedly do technical simulation. Then, a man carrying a big laptop went to Beijing to report and ask for instructions. After three years of hard work, the project was finally successful.

"This project has been particularly hard." Sun Chenhua said that the technical difficulty is high and the development progress has been delayed for nearly one year. But in order to hand over the most perfect equipment, she resisted the pressure and tried again and again, striving for perfection. In 2011, this dual-mode satellite communication system, which she and her team have worked hard for nearly 10 years, won the second prize of the National Science and Technology Progress Award with outstanding innovations of more than a dozen invention patents and sales revenue of nearly 500 million yuan.

A "spiritual leader" who plans development with an eye to the future.

Over the years, the projects developed by Sun Chenhua have achieved fruitful results. 15. Eleventh Five-Year Plan, Twelfth Five-Year Plan and Thirteenth Five-Year Plan … … Sun Chenhua has been researching and developing in the field of satellite communication, and has built the first three-tier and three-sided operation management control system of satellite communication in China. Her multi-beam and large-span rate range networking solution has broken through dozens of key technologies and developed more than 100 kinds of high-tech products, which has reached the domestic leading and international advanced level in general.

Spatial information resources are important strategic resources of the country. The integrated information network between heaven and earth is a major infrastructure of the country. Standing at the height of national needs, China Electric Power Branch concentrated superior resources and set up the project team of "Integration of Heaven and Earth", in which Sun Chenhua is one of the deputy chief designers.

"The needs of the unit are the greatest affirmation for me." After receiving this task, Sun Chenhua went into battle with his team: sorting out and breaking through key technologies, sorting out basic conditions at home and abroad, and formulating the overall scheme of "space-based access network" and "ground-based node network" … … With a solid technical foundation and many years of engineering experience, Sun Chenhua played an important role in the major project of "integration of heaven and earth", became the "spiritual leader" in this field, and personally built the national meridians.

In order to bring the project to xiong’an new area and promote the subsequent commercial aerospace development in Hebei Province, she innovatively put forward internationally leading low-orbit access network schemes such as combination of width and narrowness, functional integration, inter-satellite interconnection and global seamless service, and presided over the development of the test system. Presided over the completion of the ground application network scheme covering 15 points across the country. It is estimated that after 2020, the industrial chain driven by the integrated information network of heaven and earth will produce an output value of more than 3 billion yuan every year.

"Her hard work is beyond your imagination."

Since August 2016, Sun Chenhua has led the professional department to apply for more than 30 pre-research projects, of which nearly 20 pre-research projects have been won. Every project report needs to be PPT, and she should read every PPT carefully. When she has time, she will do it herself, and it will be midnight, and it is common to work until one or two o’clock in the morning. Especially before the defense, Sun Chenhua will accompany everyone to revise all kinds of documents and strive for perfection, never letting go of every detail.

She is in charge of many things and often travels. Pre-research project application, bidding and so on, many things should be concentrated on the weekend to deal with. Han Ning, director of the general office of the professional department of Weitong, said that she had to be consulted for a lot of work. On weekends, everyone lined up one after another like a lantern, making her often busier than usual, working almost until eleven or twelve o’clock every night. Everyone sees her hard work, and it hurts in her heart.

She sometimes asks herself: whether you work hard or not, the result will be much worse. How to choose? Do you want to choose to bloom in a limited number of years, or do you want to be mediocre and happy? Because she often looks to the future, she is still afraid to relax today when she is over half a year old. "Scientific research is grinded out. In addition to a professional foundation, engaging in scientific research must have the determination to persist in scientific research for a lifetime." In the past 32 years, she has promoted the major transformation of satellite communication from dependence on introduction to creation in China, and will devote her whole life to achieving "China leading" in satellite communication.

In the knockout stage of new energy vehicle enterprises, Xiaomi’s "high-profile" entry into new energy vehicles has brought a lot of shock to the automobile industry. Since the technical conference, the hot topic of Xiaomi Auto has been constant, and the market is expected to be full, but it is also trapped in various disputes. At present, the official press conference will usher in a countdown, and facing the real market test, Xiaomi Automobile will usher in a new round of public opinion risk impact.

Author Miao Jian Research Institute

According to the data of Miaojian Information Big Data Monitoring Platform, from December 25th, 2023 to March 24th, 2024, 1,699,200 items related to "Xiaomi Auto" and "Xiaomi SU7" have spread across the whole network, and related topics have been listed on the hot search lists of 12 platforms including Tik Tok, Weibo and Baidu, with a total of more than 230 times, and the cumulative time on the list has exceeded 1,400 hours.

Miao Jian information analysis found that

In the "price war" period, coupled with the brand impression of "high cost performance", XIAOMI SU7, the first+first Xiaomi car, has a high degree of attention, and the public opinion has crushed all other single-brand models for three months.

The topic of price runs through the warm-up period of products. Compared with design and technical topics, price is still the most concerned topic of public opinion before the products in the automobile industry go on the market.

In 3 months, there were 319 articles related to SU7, with an average of 3.5 articles published every day. Lei Jun continued to speak out through official micro by virtue of his personal influence, which played an important leading role in the overall topic communication. Timely dispel rumors, disclose important information and respond to public concerns, constantly create and form hot topics, and maintain product popularity.

On March 28th, Xiaomi SU7 will be officially released at the listing conference, and the risk window of Xiaomi Auto’s public opinion will be reopened soon. After the product is officially listed, the risk of public opinion around the final pricing combined with test drive, comparative evaluation, marketing, sales delivery, new car problems, accidents and so on will continue to rise.

01

Sorting out the main communication threads of Xiaomi SU7 before listing.

On November 15th, 2023, the Ministry of Industry and Information Technology issued the Announcement of Road Motor Vehicle Manufacturers and Products (the 377th batch) and the Catalogue of Energy-saving and New Energy-using Vehicles with Vehicle and Vessel Tax Relief (the 56th batch), in which Xiaomi Automobile is located.

The recent major communication/public opinion events of "Xiaomi Automobile" are as follows:

A On December 25th, 2023, the official blog of Xiaomi Automobile announced that the "Xiaomi Automobile Technology Conference" would be held on December 28th, and Xiaomi officially revealed the relevant information of Xiaomi Automobile for the first time.

B On December 27th, 2023, Lei Jun released a message in his personal Weibo, paying tribute to the pioneers of new energy vehicles in China, such as BYD and Weilai. That night, Xiaomi Automobile paid a grand tribute to Huawei, Tucki, Ideality, BYD and Weilai through outdoor billboards.

C On December 28th, 2023, Xiaomi Automobile held a technical conference. Lei Jun said at the Xiaomi Automobile Technology Conference: "So don’t shout 99,000, it’s impossible." "Anyone who has this kind of performance and configuration will get more than 400,000 yuan, so there is no need to talk about 149,000 yuan, or we should respect technology."

D On January 2, 2024, a spokesman for @ Xiaomi Company wrote a rumor: We recently paid attention to a picture about Xiaomi’s automobile industry chain. After verification, at least 50% of the contents were completely wrong. It said that the information summary of the "industrial chain" pictures is full of loopholes and misleading to the public and investors, which is deeply puzzled.

On the same day, some netizens discussed the price of SU7 under Lei Jun Weibo. Lei Jun said: "Is there an opponent within 500,000?" . This reply triggered speculation that the final price of SU7 may be between 200,000 and 500,000 yuan.

E On January 5th, 2024, the car blogger "Li Sir Jiaolu" released Weibo news, questioning the suspected illegal behavior of Xiaomi Auto parking service video, and its comments questioned the blogger’s double standard.

F On January 8 -10, 2024, Xiaomi Automobile released "Answering 100 Questions from Netizens" in batches.

G On January 20, 2024, Lei Jun said in an interview with CCTV: "It is expected to be officially listed in the first half of 2024, and now it is undergoing small-scale mass production. This car has a very strong configuration and a very high cost. I think everyone is joking when they shout 99,000 yuan, 149,000 yuan or even 199,000 yuan. Pricing may indeed be a bit expensive, and we will announce it at the official product launch conference of Xiaomi Automobile. "

H On January 23rd, 2024, a spokesman for @ Xiaomi Company issued a document in Weibo to refute the rumor that Xiaomi Automobile was delivered in June. Recently, there have been a lot of rumors about the delivery time of Xiaomi Automobile. The relevant information is pure fabrication, completely false. Once again, the official release and delivery time of Xiaomi Automobile are subject to official information.

I On January 30th, 2024, Wang Hua, general manager of Xiaomi’s public relations department, responded to the issue of # Xiaomi’s policy price exposure # in Weibo, saying that in recent days, everyone should have seen the internal vehicles start to be licensed, which is also to test all the processes of running through the sales and delivery, and of course, buying insurance is also one of the links.

J On February 3, 2024, Lei Jun announced in Weibo that Xiaomi SU7 was conducting a comprehensive road test nationwide to make final preparations for the listing of Xiaomi SU7, and would focus more on the automobile business.

K On February 23, 2024, it was reported that Xiaomi’s early employees close to Lei Jun revealed that "Lei Jun is making a big move. The first car owners who buy Xiaomi cars may give them licenses if they don’t have a Beijing license." In response, a spokesperson for @ Xiaomi Company responded that it was completely inaccurate. Xiaomi’s pricing, delivery and sales policies are subject to the official release, which is well known.

On February 28th, 2024, Lei Jun voiced "Apple canceled making cars" and said that "Apple users will definitely be the best choice when purchasing smart electric cars".

M On March 12, 2024, Lei Jun released the official announcement of Xiaomi Automobile in Weibo on March 28.

N On March 13th, 2024, the reporter of science and technology innovation board Daily learned from the sales channel of Xiaomi Automobile that the price of SU7 top distribution will exceed that of M5 top distribution (about 300,000 yuan).

O On March 19th, 2024, a spokesperson of @ Xiaomi Company issued a rumor, saying that the Xiaomi road test vehicle was closed-loop tested on the closed-loop expressway, and there were no violations such as high-speed illegal U-turn, speeding, and escaping high-speed tolls.

P On March 20th, 2024, Wang Hua, general manager of Xiaomi Public Relations Department, denied that "Xiaomi Automobile will issue 1000 Xiaomi SU7F codes". "As far as I know, there is no channel for priority purchase of F codes".

02

Public opinion concerns

According to the monitoring results of Miaojian Information Big Data Platform, price is the most concerned topic of public opinion. Among them, the discussion of Xiaomi automobile product itself mainly focuses on price, technology and design.

I. Price

In the technical conference and CCTV interview, Lei Jun repeatedly said "Don’t shout 99,000, it’s impossible", "Anyone with this performance and configuration will have to pay more than 400,000, so there is no need to talk about 149,000", "The price is really a bit expensive, and 199,000 is impossible", and he even replied in Weibo "Is there an opponent within 500,000?"

The "cost-effective" label of Xiaomi’s mobile phone is deeply rooted in people’s hearts, which makes Xiaomi’s car trapped by the public opinion of "low price" and "low end" before its release. From the media point of view, Xiaomi held this technical conference just to break the existing public opinion situation, and wanted to tell everyone that "we still have to respect science and technology".

On January 5th, Wang Hua, general manager of Xiaomi’s public relations department, released the ultimate rumor about Xiaomi Automobile in Weibo: until the end of the official Xiaomi Automobile product launch conference, all the information and posters with the version and price of Xiaomi Automobile were false. On January 8th and 9th, Lei Jun Weibo released Xiaomi Auto to answer 100 questions from netizens, and also officially answered questions about pricing.

On February 21st, the price of # Xiaomi Auto was searched again in Weibo, and some cars said from the media that "the current situation is even more complicated". On March 6th, Li Guoqing, the founder of Dangdang, sent a video calling Lei Jun, asking Lei Jun to price Xiaomi for 150,000 to 200,000 yuan. On March 13th, the media learned that the price of SU7 top plate will exceed that of M5 top plate (about 300,000 yuan).

The release of technology, the voice of executives, the pressure from inside and outside the industry, and the wind of prices continue. The car industry is in a big environment of "low price". Faced with the expectation of many "rice noodles", Xiaomi will insist on going upstream and entering the mid-to high-end market in pricing, or push up the consumer’s budget through marketing and kill at a low price. The continuous price topic and various speculations will make Xiaomi SU7 in the preheating stage occupy the public opinion field in the car industry.

Mainstream media: The participating media are mainly financial media such as Caijing. com, national business daily and China Business News, mainly to report the latest development of Xiaomi Automobile and the contents of senior executives’ speeches, with few media comments.

Professionals: Guess why Xiaomi Auto has not announced its pricing.

According to national business daily, Pang Rui, a well-known brand expert and founding partner of Zhansheng Communication, "So far, regarding the pricing of Xiaomi SU7, Xiaomi is mostly denying the price circulated on the Internet, without giving any positive hints. Perhaps this is also a pricing test strategy, that is, by observing the market’s public opinion feedback on different rumored prices, Xiaomi can constantly correct the price and gradually form the final pricing in the process. "

According to China Net Finance, Liang Zhenpeng, a senior industrial economic observer, believes that "on the one hand, it takes a long time for a car to go from PPT to commercial mass production, and then to improve the yield to meet the standards of product quality, process performance and other technical parameters. For Xiaomi, the cost is difficult to determine for the time being, so the price has not been disclosed yet; On the other hand, in the process of R&D and manufacturing, Xiaomi’s automobile products will continue to be iteratively updated, and the cost will continue to change, thus affecting the final pricing. "

From the media: initiate pricing speculation discussion and analyze the situation of Xiaomi SU7 according to the actions of other car companies.

Weibo-Bigu: I feel that BYD’s price reduction can kill everything. Not all of Gaohe has fallen, and Wei Xiaoli has a hard time. If BYD starts to enlarge its recruitment further, Xiaomi will be miserable.

Weibo-_-Second Senior Brother: BYD took the lead in killing the red eye within 100,000 yuan, and extremely krypton Tucki pulled the 800V to within 200,000 yuan. Therefore, the 400V single motor introduced by Xiaomi SU7 does not have the version of lidar. Once it exceeds 200,000, it will be difficult to be a new brand. Xiaomi has only one chance to play cards.

Netizen: ridicule pricing, discuss the price in mind, think about marketing routines, and discuss price reduction issues.

First, throw a confusing 300,000 yuan to the outside world, and blow the wind. When the listing is low, it will be set at more than 20, and then the whole network will say that it is cheap and buy buy will buy it.

The marketing gimmick is full, just don’t know if the final price will satisfy the public.

Almost. Aren’t you tired of this old routine?　

Rumor? I think this is what Lei Jun wants. All the way from Xiaomi mobile phone is a similar eye-catching strategy.

The price was not announced at the press conference. By understanding how much users are willing to pay for Xiaomi Automobile, pricing is made according to this price.

If it’s so expensive, you can only wait for Redmi car; As expected, it may be accepted that there are so many piles of materials at the technical conference.

Didn’t a lot of news say 500 thousand before, and now another 360 thousand, I think it’s better to wait for the press conference

BYD’s 200,000 cars haven’t been reduced in price, so we can sell them at whatever crowd we target. If BYD drops another 10,000, we will buy them from people within 100,000.

It has been delayed for too long, and there is no enthusiasm for attention.

Second, technology

Under the public opinion environment that new energy car companies generally bear the original crime of technology, the louder the slogan of "self-research" is shouted, the more attention and condemnation it attracts. Lei Jun publicized "self-research" for many times at the press conference. Later, due to the constant controversy over "self-research", the rumors mainly focused on Xiaomi V8s super motor and Xiaomi Titan alloy, and thought that Xiaomi Automobile was just an assembly plant.

These false information have been rumored one after another. On the night of the press conference, there was a voice that Xiaomi V8s super motor was from Huichuan technology, not self-developed. Huichuan technology immediately responded to "V8s motor is self-developed by Xiaomi" on the stock trading platform, but some netizens still said, "Is Xiaomi fully self-developed? How did Huichuan know?"

In addition, the Titan alloy developed by Xiaomi was thought to be plagiarized by a university teacher, and then the teacher responded that "the ingredients were wrong, and Xiaomi did develop it himself".

A picture of Xiaomi automobile industry chain was also exposed on the Internet, which shows that most parts of Xiaomi automobile are supplied by third parties. In this regard, Xiaomi Automobile denies that at least 50% of the contents are completely wrong.

Since the media: Based on the information released by the government, this paper analyzes the five major technologies of Xiaomi Automobile and whether it is "self-developed". The overall tonality of the public opinion field is neutral.

Wechat-Zinc Scale: An industry insider told Zinc Scale, "This is the same as satirizing that the large aircraft C919 is’ assembled goods’, either ignorant or with ulterior motives. The key lies in how many core technologies are mastered, not how many parts are mastered. For example, the large die-casting equipment comes from a third-party supplier, but the large die-casting equipment cluster system is self-developed by Xiaomi Automobile, and integration is also a creative ability."

Wechat-driving AUTO: In fact, how much self-developed things Xiaomi has at this conference is something that can neither be confirmed nor falsified. Because the conclusion of netizens may be just a misunderstanding. The crux of the problem lies in who owns the intellectual property rights of technology. If it is a joint development but the intellectual property belongs to Xiaomi, from the perspective of property rights and law, Xiaomi claims that there is nothing wrong with "self-research", and even from the perspective of public order and good customs in the automobile circle, it is not against it. However, if the external publicity is renamed as "joint development", the shocking effect of publicity will obviously not be achieved, and the personnel of technological subversion will not be established, so "self-research" is necessary.

Wechat-poison tongue technology: self-research in the eyes of netizens and self-research defined by the industry are often not the same thing. Xiaomi’s plan is to explore a rotor material with leading strength with partners, thus developing a brand-new motor with 27,200 rpm. Xiaomi, a die casting machine, is not self-developed. What is really self-developed is the "millet large die casting integrated cluster". In other words, Xiaomi has developed a set of most suitable and efficient production lines, and the die casting machine is also customized by partners according to the needs of this production line. This actually does not prevent Xiaomi from saying that it is self-research.

Netizen: Mainly for poking fun at/not believing in Xiaomi’s self-developed technology, and thinking that Xiaomi encountered the black water army.

Obviously, the motor you bought has to be said to be self-developed, and you are really cheeky.

Just look at the technology of millet blowing, don’t take it seriously, let’s talk about it after seeing the actual effect.

The maximum speed limit is 120. Do you think the motor is fast and useful? Don’t argue about concepts!

Boy, the technology after these years has been pre-developed successfully now.

The precipitation of other big factories for decades and hundreds of years can’t compare with Xiaomi’s research and development in one year?

A certain group stayed up late to prepare for the exam in order to do a background check for Xiaomi Automobile.

Black Xiaomi and those who blow Huawei are the same type of accounts.

Let’s just say that a tree catches the wind. What do you think is the scandal of the dying joint venture?

Now the atmosphere is very funny, saying that Huichuan can’t prove that Xiaomi is self-researched, so Xiaomi is not self-researched. So who said it? Xiaomi said it himself. Do you believe it after Xiaomi said it himself?

Huichuan is quite powerful, with the existence of the top few in China.

Third, the design

1. Appearance is similar to Porsche controversy

Since the appearance of Xiaomi automobile in the catalogue of the Ministry of Industry and Information Technology on November 15, 2023, the appearance of Xiaomi SU7 has been controversial. Because the front face and side of the car are very similar to Porsche, it is ridiculed by netizens that "Mi Shijie" is "not that Porsche can’t afford it, but that Xiaomi is more cost-effective". One plus designer Haoran said that he copied Porsche Paramera, and many self-media published the comparison chart of Xiaomi SU7 and Porsche Taycan. Some cars discovered from the media that Lei Jun Weibo once revealed that he was reading Porsche-related books; Another online picture shows that Xiaomi’s product Xiaoai’s recognition result of Xiaomi SU7 is Porsche. The superposition of all kinds of "coincidences", coupled with Lei Jun’s mention of "comparable to Porsche Tesla" and "the goal is to compete with Porsche" at the press conference, Xiaomi Automobile is caught in a "plagiarism storm".

In addition to these doubts and ridicule, there are also many professionals who speak for Xiaomi. Regarding the question of whether Xiaomi automobile plagiarized or borrowed, many disputes helped the outbreak of public opinion.

There is no plagiarism:

Domestic automobile styling design has long bid farewell to the stage of plagiarism. As for what it looks like and what nickname it is, it is the category of the media. Sometimes quite speechless, there is always an angle to black millet; In industrial design, the streamline of coupe should be beautiful and low wind resistance, and it can only look similar, which is the only choice determined by aesthetic and scientific path after industrial design develops to a mature stage.

Ridicule plagiarism:

You don’t understand, this is actually a tribute to Porsche, the predecessor of the industry; Low-key, I think it can rival the aircraft carrier; Because it is comparable, the exterior is copied from Porsche and the interior is copied from Tesla. Combined, it is perfect.

Mention that other car companies are also suspected of plagiarism, implying that sunspots "follow the trend" and "double standard":

I’m curious why many netizens plagiarized Xiaomi’s car because it looks similar to Porsche, but no one said that the car chosen by Huawei is similar to Porsche.

2. Controversy over the design of semi-hidden door handles.

In addition, the conference also announced the patented design of the semi-hidden handle. Its embedded design not only optimizes the aerodynamic efficiency of the vehicle, but also retains the aesthetic feeling of its streamlined appearance. What’s more outstanding is that it skillfully solves the freezing problem in cold weather and avoids the pop-up difficulty that traditional pop-up door handles may encounter. However, some netizens complained that this design was "very familiar", and then Lei Jun also emphasized in Weibo that the semi-hidden door handle was completely different from the early pure mechanical structure "upturned semi-hidden door handle".

3. Other design disputes

In addition, the plum blossom wheel hub, the borderless cobblestone rearview mirror and the 105L front reserve box have also been ridiculed by some netizens that "this design has existed for a long time".

03

Analysis of communication characteristics

1. Price-related topics account for a large proportion, which is the key node to arouse public opinion.

Before the technical conference, Lei Jun revealed in Weibo that "Xiaomi SU7 is a bit expensive", and the topic was on the hot search, and public opinion tended to rise. Then there is the recurring price topic: # Rice flour expects Xiaomi car to be around 300,000 # # Lei Jun said that Xiaomi SU7 has no rivals within 500,000 # # Xiaomi car policy price exposure # # Xiaomi car pricing strategy exposure # and so on.

According to the data of Miaojian Information Big Data Monitoring Platform, the high point in the communication trend of Xiaomi Automobile’s price issue almost corresponds to the high point of Xiaomi Automobile’s overall communication trend. The price issue is the main aspect that causes public opinion controversy and is the key for Xiaomi Automobile to maintain a high degree of public concern.

2. Executives and officials frequently voice and refute rumors to promote the spread of topics.

In the early stage of the new car sale, the public opinion field was flooded with false information about price and technology. Lei Jun and Wang Hua, general manager of Xiaomi Group’s public relations department, repeatedly answered questions and rumors in Weibo. The Weibo account "Xiaomi Company Spokesperson" also released rumors about pricing and sales policies, delivery time and technology industry chain. On January 8 -10, Xiaomi Automobile released "Answering 100 Questions from netizens" to comprehensively answer all questions and focus on public concern, which to some extent avoided the persistence of false information on the brand.

According to the display of Miaojian Information Big Data Monitoring Platform, every time executives or officials intervene in the topic, it will cause a certain degree of public opinion fluctuation. On the whole, Xiaomi Automobile still holds a dominant position in the right to speak in public opinion. Although it is riddled with rumors, it has caused some self-media smearing and ridicule by netizens. However, the rapid rumor-dispelling and pre-emptive public relations method not only dispels the doubts of the industry, but also provides a continuous discussion for its own products.

3. The ups and downs of brand reputation are not obvious.

Miaojian Information Big Data Monitoring Platform shows that Xiaomi Automobile has a relatively large amount of sensitive information on the day of the technology conference, the rumor of giving Beijing license, and the extremely high-level executives talking about Xiaomi Automobile at the press conference. In the three months from the technical conference to the official conference, the topic headed by price is still in the discussion stage, and the related negatives are mainly rumors, which have limited practical impact on the brand reputation of Xiaomi Automobile.

04

Public opinion risk judgment

1. Be involved in the "price war" dilemma after pricing is released.

In the year of the Year of the Loong, Tesla took the lead in price reduction, and then BYD made a low price of 79,800 yuan. Changan Automobile, Nezha Automobile and other brands followed suit, and this year’s price war began. On February 27th, the new Extreme Krypton 001 went on the market, with a starting price of 269,000 yuan. Some media claimed that "Extreme Krypton gave Xiaomi a problem". On the day when Xiaomi Automobile announced its pricing, it will inevitably bring certain "fluctuations" to the auto market. For Xiaomi Automobile, whether to follow up the price war may become a hot topic in the market. How to break through in the price knockout is the challenge that Xiaomi is about to face.

2. Repeated marketing, led by price, leads to self-attack.

The topic of manufacturing is Xiaomi’s marketing style in the field of mobile phones. When it is used in Xiaomi cars, it is the product positioning that is close to Porsche, Tesla and other high-end products after frequent price snooping and opening. The price topic was frequently searched, and the executives responded many times. Before the conference, they paid tribute to other car companies and said that they were "comparable to Porsche" …………………………………………………………………………………………………………………….

3. It is difficult to get rid of labels such as "imitation" and "cottage"

Whether it is the marketing method of the brand or the malicious smear of peers, it has been labeled as "imitating foreign models" since it came out, which can easily deepen the stereotype of the public and thus produce psychological resistance to the brand. In the car sale stage, similar teasing will continue, which will affect short-term sales to some extent. In the long run, whether Xiaomi SU7 can get rid of the negative label with a good enough driving experience, make excellent performance a competitive advantage of the product, and reverse the relatively negative market perception will also be the focus of public opinion.

4. Other negative brands, negative road test and negative test drive affect Xiaomi’s reputation.

Recently, a Xiaomi employee said on the Internet that Xiaomi will lay off employees on February 29, and "only notice, no consultation" and "no year-end bonus after being laid off", and finally said "think twice about buying a Xiaomi car". On February 3rd, a photo of a suspected collision of Xiaomi SU7 during the road test came out on the Internet, which aroused public concern. Shake consumers’ decision to buy a car. On March 19th, Xiaomi Auto officially responded that the content was maliciously misinterpreted by some accounts, and there was no violation, and it was still communicating with the expressway group on false information. Xiaomi Automobile has attracted much attention. Once the public opinion such as the negative operation of Xiaomi Group, the negative road test of Xiaomi Automobile and the negative test drive experience of new cars in offline outlets occur, it will lead to a decline in its reputation, which will easily affect the marketing process and sales of Xiaomi Automobile.

5. Brand executives’ speeches caused controversy.

Lin Bin, vice president of Netcom Xiaomi, said in a circle of friends, "Driving Xiaomi SU7 from Beijing to Shenzhen office, starting at 7: 30 on Saturday morning and arriving at Shenzhen office at 11: 00 on Monday morning, the whole journey is 2320 kilometers, passing through Wuhan and Guangzhou, and charging for 5 times. (This is a great experience.) This content triggered some speculation about the endurance of Xiaomi SU7 from the media, and concluded that the endurance achievement rate was low. Among them, the self-media account "Chatting Car" only converted electricity consumption by charging times, and the published article was not rigorous, which was complained by Xiaomi Automobile. Some also said from the media that "if it is not full every time, he will definitely explain it clearly in the text. What an important habit it is." Executives’ speeches are often easily amplified and interpreted by the media, and if there is any imprecision, it will easily lead to controversy.

6. Peer-to-peer friends’ speeches caused controversy

Regarding Xiaomi Auto’s tribute to its peers, Yang Xueliang, vice president of Geely, said that "it’s too late". "If people always want to be paid tribute, it’s over, but if people always want to pay tribute to others, there is no promise"; Zhu Ling, vice president of Krypton, also posted a blog suggesting that Xiaomi’s marketing is more and more like health care industry’s, and commented sharply that "the last one who shouted out eco-cars seems to be LeTV mobile phones". On February 27th, at the launch conference of the brand-new Extreme Krypton 001, Extreme Krypton executives talked about Xiaomi Automobile’s "marketing is worth learning", and then # Extreme Krypton executives # boarded the hot search. After the listing of Xiaomi Automobile, the subsequent announcement may also lead to such cynicism and public controversy.

On April 1st, the province responded to the novel coronavirus epidemic in emergency headquarters and issued the "Guidelines for the Prevention and Control of the COVID-19 Epidemic in Sichuan Province in 2021 (Third Edition)" (hereinafter referred to as "Guidelines")Guide）。 The Guide requires that all localities should speed up the improvement of vaccination capacity in Covid-19, adopt a combination of fixed site vaccination and roving vaccination, and vigorously promote vaccination for people over 18 years old.

The Guide requires that the vaccination progress in Covid-19 be accelerated. All localities and departments in charge of various industries should do a solid job in propaganda and mobilization, vaccination personnel mapping and organization, and strengthen daily scheduling, weekly notification and monthly assessment. Accelerate the improvement of vaccination capacity, rely on secondary and above medical institutions to set up inoculation points, use exhibition venues, stadiums, factories, enterprises, schools and other temporary inoculation points, adopt a combination of fixed-site inoculation and roving inoculation, vigorously promote the vaccination of people over 18 years old, and earnestly do a good job in monitoring the abnormal reaction of vaccination and medical treatment. Actively promote the use of "Sichuan Tianfu Health Link" for appointment vaccination.

According to the "Guide", employees in high-risk positions such as imported cold chain food, opened isolation places, emergency rooms and isolation wards in medical institutions, customs and ports, and international aviation should be tested for nucleic acids every week; Other staff of medical institutions, sampling and testing personnel of disease control institutions, supervision places and staff of old-age care institutions should conduct nucleic acid testing for all staff every month, and complete sampling testing for vaccination personnel in Covid-19; Farmers (bazaars, seafood) markets, take-away, postal services, express delivery and other service industries and labor-intensive employees should sample nucleic acid detection every month; Nucleic acid detection should be carried out in each batch of imported cold chain food packaging; Medical institutions, isolated places, farmers’ markets, cold chain food production and processing, storage and transportation related places, to conduct environmental sampling nucleic acid testing on a regular basis.

14-day centralized isolation measures were implemented for entry personnel from the port of our province. During the centralized isolation period, three nucleic acid tests and one antibody test were completed. After the entry personnel are released from centralized isolation, all localities should take them back in a closed loop (those who return to other provinces should be sent to airports and stations in a closed loop), and the community should strictly implement home health monitoring within 7 days, and conduct a nucleic acid test on the next day and the seventh day after the release of isolation. Those who come to (return to) Sichuan after completing 14-day centralized isolation in other provinces and failing to complete 7-day home health monitoring are required to carry out 7-day home health monitoring, and complete a nucleic acid test the next day and the seventh day after arriving at their destination. During the period of home health monitoring, personal protection should be done when going out to avoid participating in gathering activities.  (Reporter   Zhang Tingming   Shi Xiaohong)

　　Action plan for soil pollution prevention and control

　　Soil is the material basis of sustainable economic and social development, which is related to people’s health and the construction of beautiful China. Protecting soil environment is an important content to promote the construction of ecological civilization and safeguard national ecological security. At present, the overall situation of soil environment in China is worrying, and some areas are seriously polluted, which has become one of the outstanding shortcomings of building a well-off society in an all-round way. This action plan is formulated to effectively strengthen the prevention and control of soil pollution and gradually improve the quality of soil environment.

　　General requirements: fully implement the spirit of the 18th CPC National Congress and the 3rd, 4th and 5th Plenary Sessions of the 18th CPC Central Committee, firmly establish the new development concept of innovation, coordination, green, openness and sharing in accordance with the overall layout of "Five in One" and the strategic layout of "Four in All", conscientiously implement the decision-making arrangements of the CPC Central Committee and the State Council, base on China’s national conditions and development stages, focus on the overall situation of economic and social development, and take improving the quality of soil environment as the core. Taking ensuring the quality of agricultural products and the safety of human settlements as the starting point, we should adhere to prevention first, protection first, risk control, highlight key areas, industries and pollutants, implement classification, separate use and phased treatment, strictly control new pollution, gradually reduce the stock, form a soil pollution prevention and control system with government-led, corporate responsibility, public participation and social supervision, promote the sustainable utilization of soil resources, and build a "blue sky is always there, green mountains are always there".

　　Work objective: By 2020, the increasing trend of soil pollution in China will be initially curbed, the overall quality of soil environment will remain stable, the soil environmental safety of agricultural land and construction land will be basically guaranteed, and the soil environmental risks will be basically controlled. By 2030, the quality of soil environment in China will be stable and good, the soil environmental safety of agricultural land and construction land will be effectively guaranteed, and the soil environmental risks will be fully controlled. By the middle of this century, the quality of soil environment has been improved in an all-round way, and the ecosystem has achieved a virtuous circle.

　　Main indicators: By 2020, the safe utilization rate of polluted farmland will reach about 90%, and the safe utilization rate of polluted land will reach over 90%. By 2030, the safe utilization rate of polluted farmland will reach more than 95%, and the safe utilization rate of polluted land will reach more than 95%.

　　First, carry out soil pollution investigation and master the quality of soil environment.

　　(a) in-depth investigation of soil environmental quality. On the basis of existing relevant investigations, focusing on agricultural land and land used by enterprises in key industries, carry out a detailed investigation of soil pollution, and find out the area and distribution of soil pollution in agricultural land and its impact on the quality of agricultural products before the end of 2018; By the end of 2020, master the distribution of contaminated land and its environmental risks in key industries and enterprises. Formulate the overall plan and technical regulations for detailed investigation, and carry out technical guidance, supervision and inspection and results audit. Establish a regular survey system of soil environmental quality, which will be carried out once every 10 years. (The Ministry of Environmental Protection takes the lead, with the participation of the Ministry of Finance, the Ministry of Land and Resources, the Ministry of Agriculture and the National Health and Family Planning Commission, and the local people’s governments at all levels are responsible for the implementation.

Revise pollutant discharge standards in a timely manner, and further clarify the requirements for special pollutant discharge limits. Improve the analysis and testing methods of pollutants in soil and develop soil environmental standard samples. Local soil environmental quality standards that are stricter than the national standards can be formulated by all localities. (Led by the Ministry of Environmental Protection, with the participation of the Ministry of Industry and Information Technology, the Ministry of Land and Resources, the Ministry of Housing and Urban-Rural Development, the Ministry of Water Resources, the Ministry of Agriculture, the General Administration of Quality Supervision, Inspection and Quarantine and the State Forestry Administration)

　　(6) Comprehensively strengthen supervision and law enforcement. Clear regulatory focus. Focus on monitoring heavy metals such as cadmium, mercury, arsenic, lead, chromium and organic pollutants such as polycyclic aromatic hydrocarbons and petroleum hydrocarbons in soil, and focus on monitoring non-ferrous metal mining, non-ferrous metal smelting, petroleum exploitation, petroleum processing, chemical industry, coking, electroplating, tanning and other industries, as well as major grain (oil) producing counties and built-up areas of cities above prefecture level. (Led by the Ministry of Environmental Protection, with the participation of the Ministry of Industry and Information Technology, the Ministry of Land and Resources, the Ministry of Housing and Urban-Rural Development and the Ministry of Agriculture)

　　Strengthen law enforcement. Take the prevention and control of soil pollution as an important part of environmental law enforcement, make full use of the environmental supervision grid, and strengthen the daily supervision and law enforcement of soil environment. Severely crack down on environmental violations such as illegal discharge of toxic and harmful pollutants, illegal storage of hazardous chemicals, illegal disposal of hazardous waste, abnormal use of pollution control facilities, and falsification of monitoring data. Carry out special environmental law enforcement for enterprises in key industries, and supervise and supervise enterprises that seriously pollute the soil environment and are strongly reflected by the masses. Improve the environmental law enforcement conditions at the grass-roots level and equip them with necessary law enforcement equipment such as rapid detection of soil pollution. Carry out one round of professional technical training on soil pollution prevention and control for national environmental law enforcement personnel every three years.

(Led by the Ministry of Environmental Protection, with the participation of the Ministry of Industry and Information Technology, the Ministry of Public Security, the Ministry of Land and Resources, the Ministry of Housing and Urban-Rural Development, the Ministry of Agriculture, the State Administration of Work Safety and the State Forestry Administration)

　　Three, the implementation of agricultural land classification management, to ensure the safety of agricultural production environment

　　(seven) the classification of soil environmental quality of agricultural land. According to the degree of pollution, agricultural land is classified into three categories, those that are unpolluted and slightly polluted are classified as priority protection categories, those that are lightly and moderately polluted are classified as safe utilization categories, and those that are heavily polluted are classified as strict control categories. Focusing on cultivated land, corresponding management measures are taken respectively to ensure the quality and safety of agricultural products. Before the end of 2017, the technical guidelines for the classification of soil environmental quality of agricultural land will be issued. Based on the detailed investigation results of soil pollution, we will carry out collaborative monitoring and evaluation of cultivated land soil and agricultural products, promote the classification of cultivated land soil environmental quality in an orderly manner on the basis of pilot projects, and gradually establish a classification list, which will be completed by the end of 2020. Delineation results are examined and approved by provincial people’s governments, and data are uploaded to the national soil environment information management platform. According to the change of land use and the change of soil environmental quality, the information of cultivated land area and distribution of various categories is updated regularly. Conditional areas should gradually carry out the classification of soil environmental quality of other agricultural land such as woodland, grassland and garden. (Led by the Ministry of Environmental Protection and the Ministry of Agriculture, with the participation of the Ministry of Land and Resources and the State Forestry Administration)

　　(8) Effectively strengthen protection. All localities should classify qualified priority protected cultivated land as permanent basic farmland, and implement strict protection to ensure that its area does not decrease and the quality of soil environment does not decline. Except for the location of key construction projects stipulated by law, it is really unavoidable, no other construction shall be occupied. Large grain-producing (oil-producing) counties should formulate soil environmental protection plans. High-standard farmland construction projects are inclined to areas where priority protection farmland is concentrated. Measures such as returning straw to the field, increasing the application of organic fertilizer, less tillage and no tillage, rotation of grain and beans, reduction and recycling of agricultural film, etc. Continue to carry out pilot projects for the protection and utilization of black land. The transferee of rural land transfer should fulfill the responsibility of soil protection and avoid the degradation of soil environmental quality caused by predatory agricultural production methods such as excessive fertilization and abuse of pesticides. The people’s governments at the provincial level should give early warning to the counties (cities, districts) where the area of priority protected cultivated land is reduced or the quality of soil environment is declining within their respective administrative areas, and take restrictive measures such as limiting the approval of environmental impact assessment according to law. (Led by the Ministry of Land and Resources and the Ministry of Agriculture, with the participation of the National Development and Reform Commission, the Ministry of Environmental Protection and the Ministry of Water Resources)

　　Prevent and control enterprise pollution. Strictly control the construction of new enterprises in industries such as non-ferrous metal smelting, petroleum processing, chemical industry, coking, electroplating, tanning, etc. in areas where priority protected cultivated land is concentrated, and the existing enterprises in related industries should adopt new technologies and new processes to accelerate the pace of upgrading and upgrading. (Led by the Ministry of Environmental Protection and the National Development and Reform Commission, with the participation of the Ministry of Industry and Information Technology)

　　(nine) efforts to promote the safe use. According to the situation of soil pollution and agricultural products exceeding the standard, counties (cities, districts) with concentrated safe use of cultivated land should formulate and implement the safe use plan of contaminated cultivated land in combination with local main crop varieties and planting habits, and take measures such as agronomic regulation and alternative planting to reduce the risk of agricultural products exceeding the standard. Strengthen the quality inspection of agricultural products. Strengthen technical guidance and training for farmers and farmers’ cooperatives. Before the end of 2017, a technical guide for the safe use of contaminated cultivated land will be issued. By 2020, the area of lightly and moderately polluted cultivated land will reach 40 million mu. (The Ministry of Agriculture takes the lead and the Ministry of Land and Resources participates)

　　(10) Fully implement strict control. Strengthen the management of the use of cultivated land under strict control, demarcate areas where specific agricultural products are prohibited from production according to law, and prohibit the cultivation of edible agricultural products; To threaten the safety of groundwater and drinking water sources, the relevant counties (cities, districts) should formulate environmental risk management and control plans and implement relevant measures. The study will bring strictly controlled cultivated land into the scope of the new round of implementation of returning farmland to forests and grasslands, and formulate plans to adjust the planting structure of heavily polluted cultivated land or return farmland to forests and grasslands. We will continue to carry out pilot projects in Changsha, Zhuzhou and Xiangtan, Hunan Province to restore farmland contaminated by heavy metals and adjust crop planting structure. Pilot implementation of the farmland rotation fallow system. By 2020, the planting structure of heavily polluted cultivated land will be adjusted or the area of returning farmland to forests and grasslands will strive to reach 20 million mu. (Led by the Ministry of Agriculture, with the participation of the National Development and Reform Commission, the Ministry of Finance, the Ministry of Land and Resources, the Ministry of Environmental Protection, the Ministry of Water Resources and the State Forestry Administration)

　　Reading tips

　　Mycoplasma pneumonia mostly occurs in autumn and winter, and there are sporadic cases in other seasons. At the initial stage of infection, the symptoms are similar to those of the common cold, which should be comprehensively judged according to the onset time, clinical symptoms, physical examination, imaging examination and pathogenic examination.

　　Recently, mycoplasma pneumonia has aroused concern, and most of the patients infected with mycoplasma pneumonia in hospitals across the country are children. The disease control departments in Beijing, Shanghai, Jiangsu, Shaanxi and other places all issued reminders, and there was a peak in pediatric clinics.

　　The reporter found that the number of outpatient and emergency departments in many hospitals in Beijing has increased to varying degrees. Most of the patients are children, but many adults have been recruited. Xu Baoping, director of the Department of Respiratory Medicine of Beijing Children’s Hospital, said that since September, the number of daily outpatients in the fever and cough clinic of Beijing Children’s Hospital has increased, and about 20% of the children tested positive for mycoplasma pneumoniae. In autumn, other pathogens such as respiratory syncytial virus, influenza virus, rhinovirus, adenovirus and other infections have also increased.

　　Mycoplasma pneumoniae can be repeatedly infected.

　　The reporter learned from Chaoyang Hospital in Beijing that mycoplasma pneumonia (MPP) refers to pulmonary inflammation caused by mycoplasma pneumoniae (MP) infection, which can involve bronchi, bronchioles, alveoli and interstitial lung. Mycoplasma pneumoniae pneumonia is the most important community-acquired pneumonia in children aged 5 and above in China.

　　Mycoplasma pneumonia mostly occurs in autumn and winter, and there are sporadic cases in other seasons. Some people think that the prevalence rate of children under 5 years old is low, but it is not uncommon for young children to be infected.

　　Mycoplasma pneumoniae is divided into many categories, with fever and cough as the main clinical manifestations, which may be accompanied by headache, runny nose, sore throat and earache. Fever is mainly moderate to high fever, and persistent high fever indicates serious illness. Cough is more severe, which can be similar to whooping cough. Some children have wheezing, especially infants. The early signs of the lungs may not be obvious, and with the progress of the disease, there may be a decrease in breathing sounds and dry and wet rales.

　　Mycoplasma pneumonia is contagious. It can be transmitted by droplets and direct contact, and it can be repeatedly infected. It is not always immune once. Experts remind that if there are two or more babies at home, they need to be isolated.

　　Because Mycoplasma pneumoniae can affect both upper and lower respiratory tract, when the upper respiratory tract is initially infected, there are symptoms similar to the common cold, such as stuffy nose, sore throat and fever. Whether you are infected with mycoplasma pneumoniae and whether the infection progresses to pneumonia needs to be comprehensively judged according to the onset time, clinical symptoms, physical examination, imaging examination and pathogenic examination.

　　Dong Xiaoyan, director of the respiratory department of Shanghai Children’s Hospital, said that if school-age children have symptoms of respiratory infection, persistent fever and aggravated cough during the epidemic season of mycoplasma pneumoniae, parents should be especially vigilant, and there may be mycoplasma pneumoniae infection. If the child is clearly infected with mycoplasma pneumoniae, and there are persistent high fever, listlessness, cough with vomiting, etc., it is necessary to seek medical attention in time.

　　There are more children with mycoplasma pneumoniae infection this year than in previous years.

　　Cao Ling, director of the Department of Respiratory Medicine of the Capital Institute of Pediatrics, said in response to the media that the high incidence of mycoplasma pneumoniae infection is from August to December every year in Beijing, and it usually reaches its peak around November every year. However, as far as this year’s situation is concerned, it is hard to say when the future summit of mycoplasma pneumoniae infection will occur. There are indeed more children infected with mycoplasma pneumoniae this year than in previous years, mainly concentrated in school-age children.

　　With the high incidence of mycoplasma pneumonia in children, there are more patients with mycoplasma pneumonia in adults. It is reported that a 32-year-old patient with mycoplasma pneumonia was admitted to the Department of Infectious Pulmonary Diseases of Ningbo Hospital of Traditional Chinese Medicine recently. While he was hospitalized, the children at home were also hospitalized, and a family of three people were recruited one after another.

　　Sun Minghuan, an attending Chinese physician in the Department of Infectious Pulmonary Diseases, reminded that Mycoplasma pneumoniae is contagious. When someone at home has symptoms such as fever and cough, he should see a doctor as soon as possible, and his family should be well protected to avoid infection.

　　Adults who stay with children infected with mycoplasma pneumoniae for a long time are still not to be underestimated. Dr. Sun Minghuan said that the susceptible population of mycoplasma pneumonia is children and adolescents, but recently, the number of adult patients with mycoplasma pneumonia admitted to them has also increased significantly compared with the past. Like mycoplasma pneumonia in children, mycoplasma pneumonia in adults is characterized by fever and cough, which may be accompanied by symptoms such as headache, runny nose, sore throat and earache. Cough is more severe and paroxysmal dry cough is more common.

　　How do parents deal with mycoplasma pneumonia?

　　Does mycoplasma pneumoniae positive mean that you have mycoplasma pneumonia? Zhang Yu, a researcher at China Center for Disease Control and Prevention, wrote that, in fact, mycoplasma pneumoniae positive and mycoplasma pneumonia are two different things.

　　The result of mycoplasma pneumoniae test is positive, suggesting that the pathogen may be infected, but the infection cannot be 100% confirmed. Detection methods of mycoplasma include PCR detection of nucleic acid and ELISA detection of antibody. Mycoplasma pneumoniae positive generally means antibody positive. There are two kinds of mycoplasma antibodies: IgM antibody and IgG antibody. If IgM antibody is positive, it indicates acute infection; If only IgG antibody is positive, it suggests that mycoplasma pneumoniae has been infected. In addition, any clinical detection method has a certain false positive rate. Therefore, a positive antibody test does not mean that you are infected with Mycoplasma pneumoniae.

　　Regarding whether mycoplasma pneumonia can cause "white lung", professionals said that mycoplasma pneumonia may bring mucus plugs to block the bronchi, which in turn will cause "atelectasis", that is, the air content of the lungs will be reduced, resulting in "white lung" in imaging. But this is two concepts with the "white lung" of diffuse lesions in both lungs.

　　By tapping the back to expel phlegm, eliminating phlegm with drugs, bronchoscopy and other means, the child can be cured in a short time, and basically will not cause life-threatening. Most children with mycoplasma pneumoniae infection have a good prognosis. Children with severe and refractory mycoplasma pneumoniae infection may leave lung structure or function damage, which requires long-term follow-up.

　　How to prevent mycoplasma pneumoniae infection? Experts say that in daily life, we should first ventilate more and gather less. At ordinary times, it is best to open the window and ventilate 2 to 3 times a day at home for 15 to 20 minutes each time. Avoid taking children to crowded and poorly ventilated public places in the near future. Secondly, we should maintain good personal hygiene habits, wash our hands and rinse our mouths frequently. Appropriate outdoor activities, pay attention to physical exercise, and ensure adequate rest time. In addition, clothing should be appropriate, and clothing should be increased or decreased in time when the climate changes, with warm hands and feet and no sweat.
