Cctv news(News Network): Social security concerns people’s most concerned, direct and realistic interests. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has put the construction of social security system in a more prominent position, and pushed the construction of China’s social security system into the fast lane. At present, China takes social insurance as the main body, including social assistance, social welfare, social preferential treatment and other systems, and a fully functional social security system has basically been established.

　　Since 2012, with the in-depth implementation of the universal enrollment plan, the number of people participating in basic old-age insurance in China has increased from 790 million ten years ago to 1.03 billion, and the number of people participating in basic medical insurance has exceeded 1.36 billion.

　　From "wide coverage" to "full coverage", in order to make more insured and uninsured people have income, a sense of security, medical care and help … … Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has insisted on universal coverage of social security as the goal of building a well-off society in an all-round way, and put forward the policy of full coverage, basic protection, multi-level and sustainable development. Following this new policy, a social security reform has begun: from unifying the basic old-age insurance system for urban and rural residents to integrating the basic medical insurance system for urban and rural residents; From promoting the universal enrollment plan, reducing the social insurance rate to starting the implementation of the national overall planning system of enterprise employee pension insurance … … In the land of China, people, regardless of urban and rural areas, regions, genders and occupations, have corresponding institutional guarantees in the face of risks such as old age, illness, unemployment, work injury, disability and poverty.

　　Since the 18th National Congress of the Communist Party of China, China’s social security reform has witnessed the greatest strength, the fastest development speed and the widest coverage. It is also a period in which people are most concerned about the most direct and realistic interests and the most urgent problems are solved.

　　Liu Lingzhi, a retiree who lives in Shijiazhuang, Hebei Province, just applied for an electronic social security card online, so that she can directly "scan the code to buy medicine" in some pharmacies. Not only that, but in the future, her medical insurance credit card records and monthly pension payment will be "available online". From cards to codes, from basic social security services to diversified convenience services, social security cards are becoming more and more powerful. In addition to receiving social security benefits and handling the transfer of social security relations, they can also serve as medical cards, bus cards, park cards and library cards in some provinces and cities … … Nowadays, the number of social security card holders in China has increased from 341 million at the end of 2012 to 1.355 billion, of which the total number of applications for electronic social security cards has exceeded 540 million.

According to Sina Entertainment, Xú Zhēng said today that "it is very difficult to make movies now".

According to the news of Securities Times quoted by Sina Entertainment, the realistic movie "Retrograde Life" written, directed and acted by Xú Zhēng has been in constant turmoil recently.

This film has been criticized by many viewers as "the rich play the poor" and "consuming suffering to beautify suffering". Xú Zhēng, the film’s director and star, objected: "It’s hard to make a movie now, because making a movie can’t satisfy everyone, and everyone’s feelings are different, but if you don’t watch it, you can spray it directly, which is unfair to a movie."

He also said that after watching the movie, the audience will accept all the good reviews and bad reviews.

Geely is "unlucky" this year, but it is in a quagmire!

It is reported that the merger negotiation between Geely and Volvo will be postponed until 2021, because Geely will return to the listing of science and technology shares, and the merger can only be suspended.

As the first domestic independent brand, Geely’s market value of more than 20 billion is far less than that of the emerging forces Weilai (more than 30 billion) and Tesla (600 billion).

On the other hand, Geely has launched many electric vehicle brands, but its main product geometry is bleak, and the development of Geely’s new energy vehicles is obviously weak.

With a negative credit rating and heavy debts, why did the light of domestic cars fall here?

How did Geely, once the first domestic independent brand, break the game?

Is Geely still a car company with frequent business actions and obvious changes in executives?

The sorrow of "Brother One": Geely is no longer "Geely"

In 2017, Geely surpassed the Great Wall and Chang ‘an, and officially became the first brand of domestic independent brands in China, and it has been sitting steadily for three years. Geely’s image of "One Brother" is deeply rooted in people’s hearts.

Unfortunately, the highlight moment of self-owned brands didn’t last long. Since 2018, China’s automobile market has ended its 28-year continuous growth, and has turned into a slow decline.

Among them, the downward trend of independent brands is the most obvious. During the three years from 2017 to 2019, the total share of independent brands dropped from 43% to 39%.

Since the beginning of this year, the market share of independent brands has further declined, leaving only 36%.

As a "brother", Geely’s decline has arrived.

As can be seen from Geely’s prospectus, the total sales of Geely’s three major brands (including Lectra) in the past three years were 1,247,100, 1,500,800 and 1,361,600 respectively, which has already seen a significant decline.

In the first half of this year, Geely sold only 530,400 vehicles. Even without the impact of the epidemic, the possibility of Geely’s sales rebound is slim.

The impact of sales volume is reflected in revenue. In 2019, Geely’s performance dropped sharply by 34.67%. In the first three quarters of this year, Geely Holding achieved a net profit of 3.087 billion yuan, down nearly 50% year-on-year.

Moreover, the current liabilities of Geely Holding in the third quarter were 168.328 billion yuan, and the short-term liabilities due within one year totaled 45.724 billion yuan.

In particular, Geely’s cash flow is also declining.

At present, the net amount is only 5.219 billion yuan, and in 2017-2019, this indicator exceeded 40 billion.

However, Geely is still playing the mission of an "investment company", acquiring shares in Volvo, Proton and Lotus, acquiring shares in saxo and Terrafugia, and establishing joint ventures with China Railway and Tencent …

Geely’s response to the financial crisis is to go public in science and technology innovation board, so that it can seek public financing, which is really a good way. However, this can’t change the current decline in sales. If the car sales don’t go up, the bleak performance will continue to affect the stock price, and Geely’s follow-up pressure is not small.

Aside from the big environment, what happened to Geely, who bought Volvo against the wind?

Ten years ago, Geely’s market value was only 3 billion yuan, and Volvo’s market value was also 2 billion dollars. The news of Geely’s high-profile acquisition of Volvo was ridiculed by the industry as "snake swallowing elephant".

Affected by the financial crisis at that time, most automobile manufacturers in the world struggled in the crisis, but Geely developed six modern work brands with great fanfare, and Geely also announced that it would launch six new cars in the next 18 months and threatened to develop 42 new cars in four years.

Everyone thought Geely was crazy.

As early as 2005, when it was listed in Hong Kong, Li Shufu, the founder of Geely, entered Europe for three years and missed his ambition to enter America.

While many auto companies are still breathing, Geely is eyeing Volvo. Geely believes that Volvo is in a trough at this time, and it is bound to gain great benefits by biting its teeth to buy Volvo through the trough.

At that time, Geely changed its business philosophy from "the boss’s name is affordable car" to "safe, environmentally friendly and energy-saving car", which also coincided with Volvo’s image characteristics.

After the acquisition of Volvo, Geely was in high spirits at this time, intending to narrow the gap between BBA (BMW, Mercedes-Benz and Audi). After becoming a subsidiary of Geely, Volvo achieved an increase in sales with the help of China bonus.

But it is also cruel that Volvo doesn’t understand China.

In the next decade, competing products such as BBA promoted the localization strategy on a large scale, and more fully tapped the "China bonus" of young users and low-level cities, further widening the gap with Volvo.

BBA’s usual way of playing is to invest in film cultural products, customize advertisements, and bind its own positioning with labels such as "high-end, status", thus catering to the vast number of China consumers who are getting richer and pursuing quality of life.

What is Volvo doing at this time?

There is only one "safety card" to play. Even though Volvo is second to none in the field of safety, Geely and Volvo are relatively independent, which makes Volvo completely ignorant of China people.

"Face" and "lining", BBA chose the former and Volvo chose the latter.

That is to say, at the beginning of Geely and Volvo’s hand in hand, the agility of flaunting independent brands did not bring too many competitive chips to Geely Volvo.

Geely’s worry: exerting new energy and getting cold.

Of course, Geely will not sit still.

In 2015, Geely launched its models, and in 2018, both models were "oil to electricity", and then launched the free electric vehicle brand "Geometry".

In 2017, in order to benchmark Tesla, Polar Star became independent from Volvo and became an independent pure electric brand.

In April this year, Geely once again hatched an electric brand: Maple Leaf, and at the end of July this year, it cooperated with Mercedes-Benz to form "smart".

Geometry A, Polar Star, Maple Leaf, and smart in the future. If you add the long-distance car and London electric car under Geely New Energy Commercial Vehicle Group, there are already six new energy brands under Geely Holding.

Under the general trend of new energy vehicles, Geely is ambitious and full of energy, but no matter how you look at it, you are a little eager to achieve success.

From the perspective of brand segmentation, the geometric positioning is biased towards the middle and high end, and the maple leaf is positioned at the low end. At the same time, there are several kinds of "oil to electricity", which seem to be different brands and different positioning.

But realistically speaking, many brands of Geely are too scattered in the field of new energy vehicles. It takes resources, time and manpower to build each new brand, which leads to resource diversion, weak competitiveness and no explosion of new energy.

All Geely’s new energy sources put together are not as good as others’ new energy brands, and as long as one explosion appears, it will naturally form a chain reaction to drive other brands.

Moreover, Geely didn’t seize the time. Take Polar Star for example, Geely started to operate in 2017. At this time, the new energy subsidy is still in a stable period, and Tesla has not yet entered China, so Geely has ample room for development.

But in 2019, the sales volume of Polaris was still 0.

With limited resources, you can’t want everything. As a result, you may get nothing.

Geely has a huge system. On top of new energy projects, there are many brands such as Link. Geely cannot balance resources on new brands and technologies.

If there is another reason, it is that Tesla, as an opponent, moves too fast.

In May 2018, Tesla was registered in Shanghai, signed an agreement in July, and the site selection was successful in October. Just after New Year’s Day in 2019, the Tesla Shanghai factory officially broke ground.

Moreover, at the end of 2019, the Shanghai factory has been delivered.

In the first half of this year, Tesla Model3 sold 45,000 vehicles, far ahead of all new domestic car-making forces.

With the lapse of time, Geely’s opportunities are also disappearing. Not only the super power like Tesla is in the front, but also the new car-making forces such as Weilai, BYD and Tucki are secretly exerting their strength, and they have also gained considerable market sales and attention.

It is still very difficult for Geely to seize the opportunity to surpass it.

Geely, which is slow to shoot on new energy vehicles, missed the development time and missed the opportunity. Under the general trend of pure electrification in the next decade, how Geely can keep the market is also a problem.

finally

Just a few days ago, Geely Holding changed its CEO, and it turns out that businessmen are better at doing business.

Geely officially announced that Li Donghui officially became the CEO of Geely Holding, and An Conghui, who had previously held this position, became the president of Geely Holding.

And who is Li Donghui?

This person is very good at operation and capital operation. An Conghui, who was originally in this position, was transferred, which actually shows two development directions after Geely, one is the traditional automobile manufacturing led by An Conghui, and the other is the new technology automobile road led by Li Donghui.

It is obvious that Geely’s intention is to let a financial person build a car.

Latma Island: science and technology innovation board’s first "car", Geely A shares seek medicine.

Zinc scale: Geely’s electric PlanB: Polaris foreground geometry?

Financial Unscrupulous: The Ten-year Itch of Geely Volvo

36Kr: Nearly five months after the suspension of market news, the merger plan between Geely and Volvo will be restarted.

Flower Finance: "No wonder Geely doesn’t engage in electric cars. It turns out that there is no money!"

Auto business review: In November, there was a heavy personnel change, and Geely monopolized six fights.

　　On June 25, the Supreme People’s Procuratorate held a press conference, emphasizing the implementation of three major measures to crack down on new drugs, "dark net" transactions and other new drug crimes. The mysterious network of "dark net" has once again entered the public eye in the near future.

　　The operation is secret and the supervision is difficult.

　　The Internet is like an iceberg. What people contact and use is only the tip of the sea, that is, the "surface net", while the larger and more complex "deep net" is hidden outside the reach of the public and grows wildly. The "dark net" is an important part of the "deep net", also known as the "hidden net". Access to the "dark net" requires multiple special means, and ordinary users cannot search and access it through conventional Internet means.

　　This is also the biggest feature of "dark network". It can connect every terminal through a special network protocol, but at the same time, these terminals have no determinable IP address, but transmit through the "dark network" protocol. This means that it is extremely difficult for people to supervise the "dark net".

　　The concept of "dark net" was first put forward by American scientists. In 1996, three scientists from the U.S. Naval Research Laboratory proposed in their papers that the "dark net" came into being in order to build a system in which users could connect to the Internet without revealing their identities to the server.

　　How can I get the content on the "dark net"? First of all, we can build a "hidden server" access according to the specific coding technology adopted by the "dark network". The user’s access request will not jump directly to the destination, but will be sent along a circuitous path. In addition, you can also obtain the "dark net" content with the help of targeted crawler (a program that automatically obtains the content of web pages) and specific search engines. Because the server address and data transmission of the "dark network" are usually "invisible" and the data and passwords are protected layer by layer, it seems that people can enjoy the ultimate "freedom" in the "dark network" space.

　　Trade is rampant, threatening public safety

　　Under the temptation of this extremely private space, the "dark net" has gradually become a breeding ground for evil deeds such as black-related, terrorism-related, child pornography, selling stolen goods and money laundering, killing people and stealing goods.

　　It is also through the "dark net" that some drug transactions are bridged. The data shows that except for nearly half of meaningless data, drug information accounts for about 6.3% of the "dark net" information data, followed by extremist information, illegal pornographic information, hacker information and violent information, which also constitutes a threat to public safety and social order to some extent.

　　At the same time, privacy security is also challenged with the rampant "dark net" transactions. In August 2018, the user information of hotel chains under the hotel group was suspected to be leaked, and the seller packaged and sold 500 million pieces of guest data in the "dark net". Such a "dark net" of unscrupulous sales of citizen information once again triggered public concerns about network information security.

　　In addition, cryptocurrency has always been the biggest boosting factor for the "dark net" to mature. These cryptocurrencies with anonymous attributes enable criminals to circumvent the supervision of the government and banks and avoid the identification and tracking of relevant institutions when purchasing related "services" through "dark networks". The blockchain analysis agency released a report on July 1, saying that in 2019, the transaction volume of a virtual currency in the illegal online market of "dark net" is expected to exceed 1 billion US dollars, a record high.

　　Upgrade technology and strengthen international cooperation.

　　Using the "dark net" to commit cyber crimes has become one of the most prominent problems in the field of cyber security, and it is also the focus of international cyber security governance. In 2016, the Netan Corps of Beijing Public Security Bureau successfully destroyed a group that used Internet media such as "dark net" to spread obscene information about children for the first time, and arrested eight suspects. This case became the first case of overseas covert network crimes uncovered in China. In July 2017, the United States smashed the "dark net" black market trading website "Alpha Bay", which was the largest black market trading website smashed in the world at that time. In addition, Europol, the Netherlands, Thailand, Canada, Britain, France, etc. also participated in the action against the "dark net" black market.

　　Although countries have been cracking down on "dark net" crimes, there are still many difficulties in technology and system. Breakthrough in technical means is one of the key elements to further crack down on "dark net" crimes. Qin An, director of the Institute of Cyberspace Strategy in China, said that at present, countries have made attempts in this regard, such as establishing a "dark net" space search engine based on threat intelligence clue mining, completing the detection and collection of "dark net" entries, links and contents, and trying to actively sniff "dark net", tracking "dark net" transaction data and reasonably mastering "dark net" network structure and data resources. Continue to map the "dark net" through technical means, mine threat information, and track and confront threats from the "dark net".

　　Perfecting the system and strengthening international cooperation are also important means to crack down on "dark net" crimes. On the level of international cooperation, Lu Chuanying, secretary-general of the Center for International Governance of Cyberspace of Shanghai Institute of International Studies, believes that the main problem at this level lies in the differences in policies, laws, systems and technologies in different countries and regions. Therefore, in order to eradicate the "dark net", a cancer that threatens all mankind, we should actively promote the establishment of a comprehensive international law and mechanism to deal with the "dark net" cyber crime on a global scale, and at the same time strengthen interaction and coordination with relevant UN mechanisms and issues.

Recently, the tension of the US trade war with China has intensified. Following the imposition of tariffs on electric vehicles, its allies strengthened their control over China’s semiconductor exports, which triggered China to take rare sanctions and issued a strong warning to a wide range including 29 countries. In this context, some countries began to re-evaluate their relations with the United States and the European Union, seeking distance. With the approaching of the US election, Biden’s term of office has come to an end, but the US containment strategy towards China has become increasingly fierce. A series of tariff measures in the United States, the European Union and Canada, as well as the escalation of Dutch export restrictions on semiconductors to China, all show this trend. Faced with this pressure, China had frequent and in-depth communication with the EU since the initial investigation stage, but the other side insisted on its own opinion, forcing China to implement unprecedented countermeasures, including four major countermeasures against Canada, one of which initiated the world’s first "anti-discrimination investigation" in a pioneering way, which was not only aimed at Canada, but also intended to warn other 29 countries and countries potentially considering similar actions.

China’s tough response has caused subtle changes in the international situation, and Spain, Norway and other countries have begun to show differences from the positions of the United States and Europe. Spanish Prime Minister Sanchez and Norwegian Prime Minister Steller visited China one after another, expressing their desire to maintain dialogue and cooperation in their differences and showing their diplomatic posture of seeking win-win results for all parties. The leaders of both countries have emphasized the importance of maintaining cooperative relations with China and are unwilling to blindly follow the US policy toward China.

In addition, Turkey’s trend is particularly remarkable. Due to the stagnation of the process of joining the European Union, it actively seeks to join the BRICS framework, with a view to promoting economic ties with Russian, China and other countries, and positioning itself as a bridge connecting Europe and Asia. Behind this move, Turkey’s judgment on the changes in the global geopolitical pattern is intended to find a balance between the East and the West, and at the same time, it also reflects concerns about China’s possible counter-measures.

On the surface, this series of diplomatic interactions is an attempt by countries to avoid becoming the target of China’s counter-measures, which in essence reflects the profound changes in the global power balance. As a force that can compete with the United States, the effectiveness and determination of China’s counter-measures make the traditional alliance face a test, and the international community’s strategy towards China is divided. The current dynamic adjustment of international relations is more based on the cognition and adaptation to the new reality of strength comparison.

　　CCTV News:According to the website of China Consumers Association, in the first half of the year, consumer demand such as holiday shopping and travel continued to be released, and the regulatory authorities created a safe and secure consumption environment to boost consumer confidence. How to ensure the protection of consumers’ rights and interests in the colorful consumption experience has become the focus of public concern.

　　The China Consumers Association, People’s Daily Public Opinion Data Center and China Consumer Magazine jointly found that in the first half of 2023, the offline performance was "difficult to refund", the hotel B&B broke the contract infringement dispute, the hidden dangers of food safety problems of well-known catering brands, the poor service experience of video platform members, the infringement "trap" of research tour, the Carrefour supermarket shopping card restricted consumption, the air mileage points were cleared, and the online celebrity bamboo tube milk tea was exposed.

　　First, there is a dispute about "difficulty in refunding tickets" for offline performances.

　　Social influence: 95.4

　　Topic analysis

　　In the first half of the year, many consumers reported that they encountered problems such as "difficulty in refunding tickets" during the consumption of offline performances. Consumers complained that barley net, Fanwan Island and other well-known ticketing platforms had unreasonable measures to change their tickets and refund tickets, and topics such as "Why are concerts being refunded" were once on the hot search list of social platforms. Some public opinion has questioned that some organizers and ticketing platforms have taken measures such as real-name registration system to crack down on scalpers, but they have not matched the perfect after-sales service, and have passed on the business risks and costs to consumers, which is contrary to the original intention of protecting consumers’ rights and interests.

　　In related disputes, some ticketing platforms responded with the rhetoric that "the cultural services carried behind the tickets are characterized by timeliness and scarcity, and once the tickets are refunded, the secondary sales will be affected", but it has not been recognized by the public. Many consumers believe that tickets sold in the aviation, railway and film industries also have such characteristics, and relevant industries have introduced specific measures or actively supported the "return and change of tickets". All parties in the offline performance industry should actively refer to the experience of such industries and properly solve the infringement concerns when the offline performance market is hot.

　　Second, the hotel B&B was exposed to many infringement disputes.

　　Social influence: 90.4

　　Topic analysis

　　Before and after the May 1 holiday, the "price increase and breach of contract" of hotel homestays caused public concern, and many consumers reported that the accommodation link became a bad experience in their journey. "Women’s booking in February is approaching ‘ May Day ’ Cancelled order ""B&B ‘ May Day ’ In hot topics such as lying about being seized because of prostitution for price increase, consumers claimed that they encountered infringement disputes such as "breach of contract" by hotel operators and booking platforms during their holiday trips.

　　In fact, consumers have a certain psychological tolerance for the moderate increase in the price of holiday hotels. Consumers’ disappointment mainly stems from the fact that at the moment when the enthusiasm for traveling is high, the accommodation service that welcomes consumers is not based on more standardized management and more personalized experience. On the contrary, the merchants disregard consumers’ rights and interests for economic benefits, and they violate the contract with tricks, which undoubtedly "pours cold water" on consumers’ enthusiasm. Some consumers have questioned that some platforms are not sound enough to punish businesses for breach of contract, which leads businesses to dare to ignore consumer rights. Public opinion appeals that all parties in the hotel and lodging industry should show "sincerity" and actively change the status quo that infringement problems frequently appear during holidays.

　　Third, well-known catering brands are exposed to food safety problems.

　　Social influence: 86.5

　　Topic analysis

　　During the "March 15th" this year, in such incidents as "the blue frog in online celebrity restaurant was exposed and the kitchen was chaotic", "the meal was retrieved from the demon trash can for a long time and served to customers" and "43 cockroaches were found after Yoshinoya’s eating", the food safety problems of well-known catering brands were exposed and caused heated discussion among netizens. Many consumers called "the professional ethics of the merchants dare not compliment", "various routines make consumers lose trust" and "How many restaurants can withstand the investigation".

　　In this kind of incident, how to improve supervision and let consumers "buy with peace of mind and eat with peace of mind" in the food field has become the focus of public opinion. Some brands take well-made meals and high-quality ingredients as their selling points, and attract consumers to "pay the bill" through various marketing means. However, there may still be food safety problems that infringe on consumers’ rights and interests under their carefully created brands. Once such hidden dangers are exposed, not only the brand reputation of the enterprises involved will be lost, but also the overall image of the catering industry will be affected. Public opinion believes that standardizing online and offline interconnected catering brands and stores has put forward higher requirements for regulatory means. To protect consumers’ "safety on the tip of the tongue", we can’t always rely on "undercover" exposure, and to make supervision more "sensitive" requires exploring various paths.

　　Fourth, the video platform membership service is "discounted"

　　Social influence: 85

　　Topic analysis

　　At the beginning of this year, many members of the video platform complained about their bad consumption experiences on social platforms, including limiting the number of login devices and the definition of screen projection, etc. Some consumers thought that some practices of the video platform were suspected of infringing consumers’ rights and interests. For example, some consumers who claimed to be "seven-year-old fans" of iQiyi took Aiqiyi to court for "unilaterally changing the terms of the contract, which constituted a breach of contract". Some consumers also said that in recent years, the membership fees of video platforms such as Youku, iQiyi and Tencent Video have been rising, but the rights and interests of members have been discounted, accusing the video platform of "coercive price increase" and criticizing the video platform for "eating ugly".

　　Public opinion believes that in the fiercely competitive market environment, video platform operators can’t pass on all the pressure to consumers under various pretexts, or even "generate income" at the expense of consumers’ consumption experience. When some conventional services force consumers to pay the bill, it will inevitably lead people to question their formulation of the "overlord clause"; At the same time, when the video platform takes relevant measures to limit the reselling and dismantling of accounts, it should also avoid "accidentally hurting" the basic rights and interests of consumers. Public opinion appeals that the video platform should adopt a responsible business model in its operation, and sincerely provide thoughtful services for its members and users.

　　Fifth, the infringement of the study tour is frequent.

　　Social influence: 84.8

　　Topic analysis

　　During this year’s small holiday and summer vacation, the infringement problem in the consumption of study tours has attracted attention. Topics such as "Parents exposed their children to participate in research tours and were scolded by instructors", "Some research tours did not study" and "10,000 yuan of Qingbei research became a photo punch at the school gate" frequently appeared on the online hot search list. In this kind of incident, parents expect their children to broaden their horizons and improve their literacy through educational research tours, and they will not hesitate to pay high fees to sign up for various "research camps" for their children. However, they have encountered problems such as improper goods, mere formality and high prices. Some research projects have even been found to have problems such as inadequate security risks and staff punishing students. Many chaos makes parents and students "come on the spur of the moment and return home disappointed", which also makes many parents flinch.

　　In this kind of incident, some research institutions blurred the key information during publicity, which made parents misunderstand the real situation. There are also some institutions that "bury traps" in contracts. Once an accident occurs, they will shift the responsibility to insurance companies, individual students and even parents, which leads some parents to fall into a situation of "difficult rights protection". Public opinion calls for strengthening the standardized guidance of the "study tour" industry, promoting the survival of the fittest in the industry on the basis of protecting consumers’ rights and interests, and giving students and parents more choices, so as to achieve a win-win situation between operators and consumers.

　　Six, Carrefour shopping card to limit consumption

　　Social influence: 80.4

　　Topic analysis

　　At the beginning of January, the media reported that "Carrefour shopping card settlement is limited" was reported in Beijing, Shenyang, Kunming, Wuxi and other places. A large number of consumers said that they were restricted when paying with shopping cards after Carrefour shopping, which aroused widespread concern in society. Some consumers said that in the past, Carrefour’s shopping card could be used to pay for all goods, but now only a small number of goods can be paid by shopping card, which is suspected to be related to the operating difficulties of many Carrefour stores.

　　Public opinion believes that the incident exposed hidden dangers such as "low illegal cost of card issuers", which led to infringement problems. According to some media surveys, from the model texts of card purchase agreements in Beijing, Jiangsu and other places, the liability for breach of contract is limited to returning the balance of the gift card, and there is little agreement to pay liquidated damages to the defaulting party. This objectively leads to the situation that the illegal cost of the card issuer is too low, and it is difficult to properly solve the consumer dispute.

　　Seven, the clearing of air mileage points caused consumer dissatisfaction.

　　Social influence: 74.8

　　Topic analysis

　　On June 18th, Hu Bing, an actor, posted a video on social platforms, saying that her accumulated 500,000 China Eastern Airlines mileage points suddenly became invalid, and questioned the airline’s reminder service. For a while, topics such as airline points redemption, points invalidation, and points service have sparked heated discussions. Hu Bing’s experience is not a unique case, but a major factor that promotes the hot topic of the event. According to the media, there have been many similar complaints against other airlines before, and the problem of "clearing points" not only exists in the civil aviation field, but also involves hotels, restaurants, e-commerce and other fields.

　　Public opinion believes that the hidden dangers of infringement on members’ consumption points have long existed. On the one hand, some consumers think that the consumption points are only the benefits attached by the merchants, and they don’t pay attention to this right, and they don’t know it when their rights are damaged. On the other hand, consumers are relatively passive compared with merchants, and there is not much bargaining space in the rules of consumption points. Consumers can only "bargain" with customer service when safeguarding their own rights and interests, and it is difficult to obtain an ideal solution. Public opinion appeals that when making points into value-added services to improve users’ stickiness, businesses should show enough sincerity in setting conditions such as deduction of points, redemption of prizes, and time limit for using points, instead of just using this as a gimmick to increase new users. When consumers want to redeem points and benefits, they can’t set up many obstacles, causing infringement disputes such as "difficulty in redemption".

　　Eight, the shared charging treasure is accused of "good borrowing is difficult to repay"

　　Social influence: 74

　　Topic analysis

　　In recent years, with the continuous expansion of user scale and usage scenarios, problems such as unreasonable charging, low charging efficiency, easy borrowing and bad repayment, charging after returning, forcing false advertisements, and obtaining personal information beyond the limit have become consumers’ "slots", and "charging treasure assassins" have repeatedly appeared on the online hot search list, and related consumer rights protection incidents have attracted public attention. If a consumer spits out that in order to return the "street electricity" shared charging treasure, he actually spent more than 100 yuan on oil to drive to the original place to return it; Some consumers said that they borrowed a "search electricity" shared charging treasure, and after returning it on time, they found that they were still deducted in the early morning of the next day and felt "wronged"; Some consumers said that the "monster charging" charging treasure rented in different locations was three times more expensive than borrowing it for three hours, questioning the "pricing mystery" of charging treasure.

　　In related disputes, compared with operating companies, consumers are often in a weak position. In the process of safeguarding rights, they need to negotiate and communicate with operating companies many times, which takes time and effort to recover losses, and sometimes they are delayed, shirked and even deadlocked by operating companies. In addition, some consumers may fail to detect the wrong deduction of fees or privacy disclosure in time, resulting in damage to their rights and interests without knowing it. Public opinion believes that solving the current situation of frequent problems in the shared charging treasure industry requires the participation of all parties and joint management. In addition to clearly marking the price and other matters, enterprises also need to clearly indicate the consumer complaint feedback channels to improve the efficiency of consumer dispute resolution.

　　Nine, online celebrity bamboo milk tea was exposed to food safety issues

　　Social influence: 73.7

　　Topic analysis

　　"Bamboo milk tea" is a new product in online celebrity in the second quarter of this year. However, controversial issues related to it are also emerging on social platforms. Some consumers have reported that the "bamboo milk tea" sold by some merchants is not only expensive, but also tastes worse than expected, and even there are food safety hazards. If a netizen sends a video exposure, a tea shop in Tangqi Scenic Area in Hangzhou "cleans the moldy bamboo tube and prepares it for milk tea"; Some media exposed that the bamboo tubes of the bamboo tube milk tea shop in Nanjing Confucius Temple Scenic Area were directly labeled and sold to customers without disinfection, infringing on consumers’ right to safety and security.

　　In the highly competitive new tea market, "bamboo tube milk tea" is a marketing attempt made by merchants to conform to the trend of "face value economy", and its popularity shows that this kind of product has a side that suits consumers’ preferences. However, frequent disputes show that the internal quality of this product is still difficult to satisfy the public. Public opinion calls for businesses not to trample on the "red line" of food safety in pursuit of profits, and relevant departments should continue to strictly supervise such "online celebrity" products to effectively protect consumers’ rights and interests.

　　Ten, low-cost tour groups hidden compulsory shopping problem.

　　Social influence: 64.3

　　Topic analysis

　　On June 4th, some netizens posted videos on social platforms. A female tour guide of a tour group in Yunnan forced tourists to buy goods, and satirized the dissatisfied tourists for being "indifferent, selfish and shameless", and the low-cost tour "forced consumption" infringed on consumers’ rights and interests, which caused heated public opinion. In addition, some media surveys have found that there are many chaotic phenomena such as "changing the itinerary at will", "killing customers", "compulsory shopping" and "tourists being stranded" in the low-cost tour groups for the elderly launched by some travel agencies.

　　Some consumers said that the problem of infringing on consumers’ rights and interests, such as low-cost group compulsory shopping, has become a "chronic disease" mainly because tourism, as an experiential consumption, can only judge its advantages and disadvantages after experience, which makes it difficult to safeguard rights. Especially after disputes arise, travel agencies often hinder consumers’ complaints on the grounds that the specific itinerary details, the number of shopping spots and the length of stay are not agreed in the contract. Public opinion appeals that during key periods such as holidays, relevant departments should pay more attention to consumers’ complaints and reports about violations of consumers’ rights and interests by low-cost tours, and accurately crack down on illegal activities such as deceiving registration, concealing rules, and compulsory shopping, so as to eliminate "black-hearted merchants" who do not live up to their names, ensure the normal order of the tourism market, and let tourists enjoy a comfortable journey.

　　On the whole, all parties in the industry are actively exploring various measures to improve the consumer experience, but it also exposes many potential risks of infringement. First, some businesses or platforms have inadequate rights and interests protection measures, which are inconsistent with the actual needs, resulting in some safeguards not being effective, or forming new rights protection difficulties and lacking "sincerity". Second, when some operators carry out online celebrity marketing, they only pay attention to the appearance of commodity packaging and the flow of brand communication, but ignore the inherent quality assurance of products, which has become an IQ tax that consumers dislike. Third, practitioners in some industries take advantage of consumers’ pursuit of "good quality and low price" to "cheat consumers" by sacrificing service quality and even infringing on consumers’ rights and interests, which leads to constant controversy. At the moment of promoting the sustained recovery of consumption, it is expected that all parties in the industry will take the protection of consumers’ rights and interests as an important part of their long-term planning in the subsequent development, taking into account their own interests and the legitimate rights and interests of consumers, and completely change the frequent and high-incidence situation of infringement problems in some fields.

Introduction

Time flies, and 20 years have passed like a wonderful long-form drama. Now, Zhang Jiahui, a legendary superstar in the Chinese film and television industry, has decided to write a new chapter in this drama of his life. He joined hands with powerful actress Hu Xinger and the new generation of Xiaosheng Zeng Shunxi to participate in the filming of the Youku criminal investigation drama "Blood of the Humble Dog", bringing the audience an audio-visual feast that spans time and space. This news was like a stone thrown into a calm lake, causing countless ripples, triggering the public’s enthusiastic attention and expectation for this drama.

Main characters and background, Zhang Jiahui: The Best Actor’s Screen Return

Cheung Ka Fai, the best actor who conquered thousands of audiences with his superb acting skills and low-key and restrained temperament, has created many characters that have been deeply rooted in the film and television industry since he stepped into the film and television industry in 1989. Whether it is the cold killer in "Witness" or the down-and-out boxer in "Guild Wars", his performances always accurately capture the soul of the character and give it life. Despite his brilliant achievements in the field of film, Cheung Ka Fai’s love for TV dramas has never diminished. His last starring role in a TV series can be traced back to the 2004 TVB classic "Tianya Hero Doctor". This return after a lapse of two decades is not only an important turning point in his personal artistic career, but also an affectionate look back on the golden age of Hong Kong TV dramas.

Xinger Hu: The Muse of Power

Wu Xinger, a tenacious force in the Hong Kong film and television industry, is widely praised for her solid acting skills and diverse character-building abilities. After participating in the Miss Hong Kong election in 1999 and winning the third place, Wu Xinger quickly rose to the forefront of TVB, participating in many well-known works such as "Up to the Sky" and "My Savage Grandma", and won the crown of the TV series many times. She and Zhang Jiahui have worked together tacitly in works such as "Street of Rage", and this time they joined hands again, which undoubtedly injected a strong chemical reaction into "The Blood of the Dog".

Zeng Shunxi: The new generation of forces is ready to go

Zeng Shunxi, as a rising star in the mainland film and television industry in recent years, has won the love of young audiences with his sunny and handsome image and increasingly mature acting skills. From "The Best Time of Youth" to "Yitian Dragon Slayer" and other works, he has shown great performance potential and character control. Joining "Blood of the Dog" this time, with his predecessors Zhang Jiahui and Hu Xinger on the same stage, is undoubtedly an important experience in his acting career, and will also add a touch of youthful vitality to the series.

An Overview of the New Drama "Blood of the Dog"

The Blood of the Pigeon Dog is a masterpiece of criminal investigation directed by former TVB gold medal team Su Wancong and written by UEFA Champions League. The drama takes complex and tortuous cases as the main line, deeply analyzes the light and darkness of human nature, and shows the fierce collision of justice and evil. Su Wancong and UEFA Champions Ying, a golden partner, have worked together to create many well-known masterpieces, such as the "Apostle Walker" series. Their addition has undoubtedly provided a solid guarantee for the quality of "Blood of the Pigeon Dog".

Shooting plan and location

According to reports, "The Blood of the Pummy Dog" is scheduled to start shooting at the end of September this year, and the crew will shoot in Macau and Jiangmen. These two cities full of story history not only provide a rich and diverse visual background for the series, but also have a deep connection with the Hong Kong TV drama industry. Macau’s unique cultural blend of Chinese and Western cultures, as well as Jiangmen’s historical sedimentation as an important city in the Pearl River Delta, will add a strong regional color to the plot, making the audience feel as if they are in the story.

Zhang Jiahui’s return significance

Zhang Jiahui’s return is not only a continuation of his personal artistic pursuit, but also an affectionate tribute to the style of traditional TV dramas. He admits that TV dramas give actors more abundant performance space, allowing them to dig deeper into the connotation of characters, which is why he misses and longs to return. Facing the new script and character challenges, Zhang Jiahui expressed his expectation to surpass other versions and pass on the "performance torch" in his hand. At the same time, his working partnership with Hu Xinger foreshadows that there will be wonderful antagonists waiting for the audience in the play.

Audience expectations and market reaction

As soon as the news came out, the majority of fans and the media responded enthusiastically to Zhang Jiahui’s return, and expressed their eagerness for "Blood of the Dog". On social media, the relevant topic trendiness continued to soar, which was enough to foresee the market potential of the drama after it was broadcast. Zhang Jiahui’s appeal, Hu Xinger’s stable play, and Zeng Shunxi’s fresh blood are expected to trigger a new round of drama chasing craze, injecting a boost into the long-sluggish Hong Kong TV drama market.

conclusion

Overall, "The Blood of the Hump Dog" not only carries the ambition of Zhang Jiahui to fight for the screen in 20 years, but also inherits and carries forward the spirit of the golden age of Hong Kong TV dramas. This work, which brings together the best actor, the queen and the new generation of actors, is expected to become an annual hit series with its excellent production, gripping plot and profound character portrayal, which has far-reaching significance for Zhang Jiahui personally and the entire Hong Kong TV drama industry.

Let’s look forward to the brilliant bloom of "The Blood of the Dog", witnessing how Zhang Jiahui, Hu Xinger, and Zeng Shunxi interpreted a police and bandit situation intertwined with crime, redemption, and human nature in the play, presenting a visual and spiritual double feast for the audience.

Responsible editor:

　　April 7th is World Health Day. This year, the World Health Organization has set the theme as: supporting nurses and midwives. In China, this year’s publicity theme is "Pay tribute to medical care and fight against the epidemic together". The reporter of Health News interviewed Jiao Yahui, the supervisor of the Medical Administration and Hospital Authority of the National Health and Wellness Commission in Wuhan, Hubei Province, focusing on the mainstay of anti-epidemic — — Nursing team.

　　● 70% of the medical aid team in Hubei are nurses, and there are more young people after 90 s and 95 s. They have practiced the Nightingale spirit well.

　　● Nurses have a particularly heavy workload and undertake professional nursing, life nursing and even trivial work, which is really hard.

　　● Compared with physical care, nurses play a greater role in psychological comfort. This is the real holistic nursing.

　　● Give nurses more training opportunities, invest in nursing-related projects and improve nurses’ salary.

　　Health News: How many nursing staff are there in the medical teams that rushed to Hubei and Wuhan? What is the principle of redeployment?

　　Jiao Yahui: This time, the nurses practiced the Nightingale spirit very well. The front-line nurses are all Nightingale, which is excellent. Specifically, there are 343 local teams with 38,632 people, including 26,530 nurses. In other words, nearly 70% of the rescue team are nurses.

　　At the beginning, the number of patients was relatively small, and the number of nurses sent was relatively small, mainly specialist nurses, such as nurses responsible for bedside hemofiltration treatment. At that time, there were dozens and hundreds of people in the rescue team. At the same time, because the shelter hospital was not built at that time, and the nursing staff in the designated hospitals were the most scarce, the specialized nurses who rushed to help were sent to the designated hospitals.

　　One day, I was particularly impressed. On January 27th, entrusted by the Supreme Leader General Secretary, Premier Li Keqiang, leader of the Central Leading Group for novel coronavirus’s response to the pneumonia epidemic, came to Wuhan to inspect and guide the epidemic prevention and control work, and to visit the medical staff who expressed condolences to patients and fought in the front line. That is, on that day, we received the task to send 800 intensive care nurses to Wuhan.

　　Later, the shelter hospital was built, and the mild and severe patients were separated. At the same time, we began to organize the medical team. Since then, nurses have basically never been sent alone.

　　When people arrive, they will match different human resources according to different positions. For example, in intensive care, it is basically a specialist nurse. However, there are mostly mild patients in Fangcang Hospital, and general nurses provide nursing services.

　　There is also a remarkable feature of the nursing team that rushed in this time. There are more young people after 90 s and 95 s, and many support hospitals have also sent male nurses.

　　Health News: In the front line of anti-epidemic, medical staff are "dancing with wolves" all the time. What are the challenges for nurses?

　　Jiao Yahui: In this battle, the workload of nurses is particularly heavy. From professional nursing, to life nursing, to some trivial work, all should be done by nurses.

　　During the epidemic period, many hospitals have no nurses, cleaning staff and workers. Nurses should not only feed patients with water and food, but also do basic care, such as turning over and patting their backs, as well as specialized care, such as hemodialysis. At the beginning of the epidemic, medical oxygen was insufficient, and nurses turned into porters, wearing uncomfortable protective clothing and pushing nearly 100 kilograms of oxygen bottles to the isolation ward.

　　Nurses are really hard. In the quarantine area, nurses stay longer than doctors. On duty at night, doctors can rest, but nurses can’t. In the early days, there were not enough protective materials, and many nurses had to wear a suit for seven or eight hours. During this period, they didn’t eat, drink or go to the toilet. In addition, at work, they all need to wear double gloves to operate, such as infusion, which is more difficult.

　　There is also a reality: the number of specialized nurses in the fields of severe diseases and infectious diseases in China is far from meeting the needs of fighting the epidemic, and a large number of nurses come from other professions, such as internal medicine and surgery. Once, I met a stomatological nurse in the ward. For them, the initial pressure is even greater. In order to ensure the quality and safety of medical care, medical teams and institutions have made great efforts in infectious disease nursing expertise and hospital infection prevention and control, and have been training continuously.

　　There is a detail that moved me — — Many nurses cut their hair short to reduce infection, and some even shaved their heads. For them, this is also a significant decision. Two days ago, when I sent the medical team back, I saw many people with small hair stubbles. They were so young and lively.

　　Health News: In this epidemic, what are the outstanding functions of nurses?

　　Jiao Yahui: Compared with physical care, the greater role of nurses lies in psychological comfort. COVID-19 is a severe infectious disease, and family members can’t accompany them. At this time, nurses have replaced the role of family members and given them care in words and actions. For example, for the patient’s birthday, painting, singing, while feeding water and food. Many medical staff bring their own milk, millet gruel and clothes to patients. What they have done has gone far beyond the scope of psychological counseling, and more is to comfort.

　　In my opinion, this is the real holistic nursing. In normal times, although everyone has been emphasizing and practicing quality nursing, they always feel a little worse. But in this special period and environment, everyone cares and takes care of every patient spontaneously and naturally, without education and words.

　　In fact, the goal of holistic nursing is to provide the best care for people according to their physiological, psychological, social, cultural and spiritual needs. Nurses should not only pay more attention to the patients themselves, but also pay attention to the factors that affect the patients’ recovery, such as their environment, psychological state and physical factors.

　　The daily system represented by holistic nursing has played a very important role in the prevention and control of this epidemic. They were not established because of COVID-19. They are all common core systems, such as the medical quality system that has been emphasized all the time, and the establishment of difficult case discussion, death case discussion and critical illness system by combining medical department, nursing department and hospital feeling office.

　　Health News: Last May, in Geneva, Switzerland, the World Health Assembly designated 2020 as the International Year of Nurses and Midwives. Tan Desai, Director-General of the World Health Organization, said, "Nurses and midwives are one of the pillars of health systems in all countries, and countries are called upon to invest in nurses and midwives in 2020, and strive to realize the promise of health care for all." What do you think of the word "investment"?

　　Jiao Yahui: First, nurses should be given more opportunities to receive training and strengthen their professional skills. Second, invest in the related work of nurses. For example, nurses need to develop nursing projects, as well as training materials and consumables, all of which need financial support. In addition, a reality that can’t be ignored is that the aging is becoming more and more serious, and the demand for nursing in families and communities is far more than medical care, and the on-site service of nurses is becoming more and more urgent. In this regard, how to make home care feasible and sustainable requires the state to provide funds or allow related services to be charged. Third, improve the salary and treatment of nurses, so that the income of nurses can match the workload and work pressure.

　　Health News: The epidemic situation has also left many reflections. What are the thoughts on the training of nursing staff?

　　Jiao Yahui: This big exam reminds us that the training of nurses should be a combination of basic nursing and specialist nursing, and both should be strengthened. Before, the contradiction of the shortage of specialized nurses was not prominent, but the epidemic situation fully exposed this contradiction. For example, nurses in the field of infectious diseases usually receive less training in critical illness and have weak coping ability, which is a shortcoming.

　　In addition to the prominent demand for specialized nurses, more exposed problems are that basic nursing needs to be further strengthened. After all, the main body of the nursing team in China is general nurses who can do basic nursing. In fact, both specialist nurses and general nurses must be able to do basic nursing first. On this premise, we will train specialized nurses. If we simply emphasize specialist nurses without basic nursing support, it will not only affect the nursing effect, but also affect the whole treatment result. For example, some serious patients have been hospitalized for a long time and have pressure ulcers, which means that the obvious basic nursing is not in place and needs to be corrected immediately.

　　In fact, in addition to nursing, the epidemic has also exposed some shortcomings in the medical and public health system. For example, in the treatment of infectious diseases, breathing, multi-organ support and other treatments are a weakness; During the treatment, some general hospitals requisitioned did not meet the requirements of infectious disease facilities, and there were no three areas and two passages, and the ventilation, heating and oxygen did not meet the requirements. The reserve of medical materials is even more fragile. Due to the previous policy of zero inventory and zero difference rate, there are almost no emergency materials in hospitals. Therefore, there should be an overall consideration in the future, because these shortcomings are not only in nursing and medical care, but also in system construction and material reserve.

The epidemic is merciless, and donations warm people’s hearts. In recent days, the COVID-19 epidemic in Hainan Province has touched the hearts of countless people, and all sectors of society have actively donated epidemic prevention materials to help the epidemic prevention and control work with practical actions.

The Provincial Women’s Federation issued a donation to the group members in the "Hainan Women’s Federation System Capacity Enhancement Reading Group" to mobilize everyone to cheer for Hainan with practical actions. By 23: 00 on August 15th, 77 people had donated money, raising 16,700 yuan, including 63 people from Group Solitaire.

The All-China Women’s Federation and the China Women’s Development Foundation have collected more than 520,000 yuan worth of medical surgical masks, family standing medicines, hand-washing-free disinfection gel and other caring materials. At present, the first batch of 100,000 medical surgical masks donated by Changzhou Meisheng Biomaterials Co., Ltd. has arrived in Lingshui County on August 15, and other materials are being sent to Hainan one after another, and will be put into Hainan’s anti-epidemic front line in the near future.

With the efforts of Hainan Women’s Federation, Guangdong Women’s Federation, Guangdong Women’s and Children’s Foundation and Deng Lao Jinfang Pharmaceutical Science and Technology Group donated 20,000 boxes of Deng Lao Qing Guan Drink (No.1) to Sanya. On the morning of August 15th, anti-epidemic materials were delivered to Sanya Red Cross Society, which distributed them to frontline medical staff and volunteers to relieve the heat and cool them down.

In order to thank the frontline anti-epidemic workers for their efforts and help the charity Hainan No.4 Action, Danzhou Red Cross Society, Danzhou Women’s Federation, Hainan Media Center, Hainan Music Broadcasting Coconut FM and the caring company Nanguo Baby jointly launched the "Concerted Anti-epidemic Hainan Must Win" action to help Danzhou. After many efforts to purchase and unite major maternal and infant brands, Nanguo Baby donated milk powder, hand sanitizer, nutrition and other maternal and infant protection materials worth more than 80,000 yuan to Danzhou City.

On August 13th, Danzhou Shuyue Mummy Yuezi Center, Hainan Xiermeiyue Health Management Co., Ltd., Danzhou Women’s Federation, Nada Town Chamber of Commerce, Yongyexing Consulting and Evaluation Group, Danzhou Jinliufu Lucky Jewelry Store and other caring enterprises jointly launched the "Concerted Fight Against the Epidemic in Hainan" campaign to help the frontline anti-epidemic workers with caring materials, with a total value of 12.

Since August 8th, Muchen Chicken Dunteng Sweet Shop in Danzhou City has donated 1,336 sugar water, 100 packages to medical staff and volunteers, and donated 105 mops for epidemic prevention. The company said that it plans to give 100 sugar water to the epidemic prevention line every day in the future.

Lingshui County Women’s Federation, Federation of Industry and Commerce and County National Defense Sports Association gave full play to the advantages of "Lian", mobilized enterprises to practice social responsibility, actively contacted manufacturers and major supermarkets to raise materials, and after many contacts, donated 290 boxes of mineral water and 20 boxes of instant noodles to the anti-epidemic front line.

Party member Huang Lingyan, a caring female entrepreneur in Lingshui County, donated 3,000 Jin of wax gourd to Yingzhou Town.

Later, Huang Lingyan contacted caring enterprises to donate masks, instant noodles, bread and other epidemic prevention materials to the grassroots epidemic prevention and control line, and helped the epidemic prevention and control work with practical actions, contributing to Lingshui’s victory in the epidemic prevention and control war.

Thanks to the efforts of women’s federations at all levels in the province, love donations are still coming together, bringing care from the whole society to the front line of anti-epidemic, contributing to winning the battle against epidemic at an early date!

How is your pure electric car experience in the cold winter?

The discount on battery life may not be the worst thing. Recently, more than a dozen Tesla owners in Canada have reported that even the air conditioner can’t be used in winter. Not only is the car frozen at a discount, but people are also frozen with a snot and tears.

Moreover, the basic things that can’t be heated in winter are heat pump air conditioners.

This is very strange. The high-efficiency and energy-saving advantages of heat pump air conditioners have not been brought into play, but they cannot be heated, which has attracted the doubts of some Canadian car owners and attracted the attention of Tesla’s R&D team. Musk said that this is a high priority for Tesla.

But even weirder, Musk said that the failure of heat pump air conditioner turned out to be a software problem, which can be completed by firmware update. Perhaps many people have never heard of it, and air conditioners still need OTA. However, after understanding the structure and working principle of Tesla heat pump air conditioner, we can find that this set of hardware can realize 12 different functions, and all the functions are controlled by software.

Therefore, the problem of Tesla heat pump air conditioning may really be a software problem.

So, how amazing is Tesla’s heat pump air conditioner? Why can’t refrigeration occur under extremely cold conditions? Can the industry solve this problem? After reading the patent of Tesla heat pump air conditioner and having a conversation with the Weiling engineer of Midea, the car found the answer to the question.

This month, countries in the northern hemisphere ushered in the coldest time since winter, and electric vehicles also entered the worst stage of the year.

Recently, Tesla owners in Canada reported that they were driving in an extremely cold environment and the heat pump air conditioner could not be used.

Twitter user @TSelvig said that when traveling that day, the temperature had dropped to-40 C. In this extremely cold weather, when he was driving Tesla Model Y, the heat pump air conditioner could not be used. After trying to restart the vehicle and call Tesla customer service, this problem still cannot be solved, and the owner is a few hours’ drive from the nearest service center, so it is impossible to drive without air conditioning.

In the end, the family switched to a fuel car.

Another Model Y owner @paateach has a richer experience. His Model Y has no warm air for two consecutive winters.

He tweeted that he lived in Saskatchewan, southern Canada, and in February last year, he encountered the situation that the heat pump air conditioner could not be used, and there was no warm air for a whole month. Later, Tesla replaced a group of super manifolds for him, and the heat pump air conditioner could be used at that time. However, by this winter, when the temperature dropped to -30℃, he once again encountered the situation that the heat pump air conditioner could not be used.

At that time, he photographed the prompt on the car screen: the cockpit climate control system needs maintenance, and the heating and cooling systems will be restricted or unusable.

Two car owners questioned Tesla: Why did Tesla’s heat pump air conditioner fail in extremely cold weather? Tesla has been repaired several times, why is the maintenance plan still invalid?

Some car owners even said that after this winter, they hope to sell their Tesla in exchange for a fuel car, at least there will be no air conditioning and heating failure.

Angie Dean, chairman of Tesla Owner’s Club in Alberta, Canada, said: "In Alberta and Saskatchewan, Canada, more than a dozen Tesla owners have experienced the problem that heat pump air conditioners cannot be used."

Just last week, the owner community Drive Tesla Canada tweeted @ Musk, asking him to comment on the heat pump problem. Musk replied to the tweet within 5 minutes, saying that maintaining the heat pump air conditioner has a very high priority. After 40 minutes, Musk said that the new firmware of heat pump air conditioner has been introduced to users.

It is quite curious that why the failure of heat pump air conditioner can be repaired by firmware update? In addition, after the firmware update is completed, there is still feedback from the owner that heating cannot be done. Is the firmware update useful?

In a patent document published by Tesla in 2019, the structure and operation mode of the heat pump air conditioning system were demonstrated. At the beginning of 2020, with the mass production of Model Y, this patent was also transformed into the mass production application of Tesla.

If you open the front case of Tesla, you can see the heat pump air conditioner and many pipes and harnesses. In fact, this is just the tip of the iceberg of the heat pump system. From the patent drawing, Tesla’s heat pump air conditioner has 11 main components, and is responsible for the thermal cycle of the whole vehicle, which can lead to different parts of the vehicle such as cockpit, battery pack and motor.

These main components are compressor, cabin condenser, cabin evaporator, battery system cooling device, cabin blower, motor liquid-cooled condenser, storage battery, three-way compressor air outlet, low-voltage electric cabin heater (PTC), recirculating air conditioner and heating.

Among the 11 main components, Tesla did not directly cancel the traditional PTC heating, but still equipped with a low-voltage PTC heating. However, due to the lack of power, this PTC heating device can not directly heat the cabin, but provides auxiliary heating when the heat pump system is insufficient.

Surprisingly, Tesla’s hardware can realize 12 different working modes, which are completed by different software scheduling.

Among these 12 working modes, there are only three modes in which heat pump participates. Heat pump participation in heating can be divided into pure heat pump mode and mixed heating mode. When the heat pump efficiency is high, the pure heat pump mode is activated, and when the efficiency is low, the mixed heating mode is activated. The heat pump can be mixed with PTC heating and can also be added to the evaporator for heating together.

In addition, the cabin and battery system can be heated simply by using the compressor and evaporator. In addition, the in-vehicle thermal circulation system can also realize the functions of cabin defogging, defrosting, dehumidification and so on.

A conclusion can be drawn here: it is indeed feasible to fix the problem of heat pump air conditioning through firmware update.

When there is nothing wrong with the hardware of the heat pump air conditioning system, the adjustment of the heat pump air conditioning system can be realized by adjusting the software scheduling in different environments.

As far as the heat pump system is concerned, there is a strong relationship between the efficiency of heating the cabin and the efficiency of the heat pump. Because the working principle of heat pump air conditioning is to exchange heat energy inside and outside the car.

Through the evaporator, the refrigerant can absorb heat from the external environment, and after the refrigerant in the car is liquefied, it releases heat, so that it can heat the cabin.

However, if the temperature of the external environment is lower, it is more difficult for the refrigerant to obtain heat from the external environment, which leads to the low heating efficiency of heat pump air conditioning in extremely cold environment.

Tesla also knows this obvious problem, so it adds auxiliary heating devices in addition to heat pump air conditioning.

Tesla drew a chart in the patent, which can explain the efficiency of heat pump air conditioning at different temperatures. The efficiency coefficient of heat pump air conditioning is expressed by COP(Coefficient of Performance). When COP=1, it means that the consumed electric energy is equal to the generated heat energy. When COP>1, the heat pump air conditioner is in the high efficiency area, which means that it can get more heat energy by consuming less electric energy.

As can be seen from Tesla’s chart, when the ambient temperature and battery temperature are lower than -20℃ at the same time, the efficiency of heat pump air conditioning will be very low, which is also considered as extremely cold temperature by Tesla, and there is no solution below this temperature. But at this time, just heat the battery, the COP value will increase, and the heating system can be used normally.

When COP=1, the heat pump air conditioner does not work and relies on evaporation to achieve heating. When COP≥1, the heat pump air conditioner will participate in heating, and the temperature needs to be above -10℃.

The second conclusion can be drawn here: if the weather outside is extremely cold, even if the firmware of the heat pump air conditioner is updated, the heating effect will still be poor. The solution is to heat the battery, or preheat it before going out.

However, under the tweet that Musk replied to the updated firmware, there are still many users who feedback that the vehicle still cannot heat.

Then, there is probably a hardware problem.

Tesla owner @paateach said on Twitter that his Tesla Model Y has been replaced with two super manifolds, including the sensor of heat pump air conditioner, expansion valve and refrigerant pipeline. The heating system can be used temporarily, but I am very worried that it may be damaged again.

Twitter user Tesla owner revealed the research and development story of heat pump air conditioner online. Recently, Tesla’s engineers in California and Alaska are testing heat pump air conditioners. The test results show that Tesla’s heat pump air conditioners can work normally below -30℃ because the heat pump air conditioners have two refrigerant cycles.

At the same time, engineers also found the problem: in extremely cold weather, the cover plate of the front air inlet will be frozen and damaged, which will lead to the inhalation of cold air during driving. Because the cold air temperature is too low, the sensor will report an error to the system after sensing it. At this time, the compressor will stop working and the heating will stop.

In order to solve this problem quickly, Tesla may start the compressor by software, temporarily avoiding the heating failure in extremely cold weather. But to solve this problem completely, Tesla may need to update some hardware later.

For the automotive industry, heat pump air conditioning is still a new thing, and Tesla Model Y was mass-produced in early 2020. Prior to this, pure electric vehicles generally used PTC to heat the interior of the car. But even under ideal conditions, the COP of PTC is 1. Low efficiency leads to very large electricity consumption for PTC heating, which further becomes a major factor affecting the battery life of electric vehicles in winter.

The efficient performance of heat pump air conditioning has attracted the attention of electric vehicle companies. In 2021, all new pure electric vehicles were basically upgraded from PTC heating to heat pump air conditioning. However, due to the limitation of refrigerant, when the temperature is below -10℃, the efficiency of heat pump will be greatly reduced. At this time, it is necessary to rely on PTC heating to heat vehicles.

For example, Tucki P5 is equipped with a heat pump air conditioner to achieve efficient heating, but it is also equipped with PTC. When the temperature is lower than -10℃, the vehicle will start PTC heating to heat the interior.

It can be said that Tucki P5 has solved the shortcomings of heat pump air conditioning to some extent, but it has not been completely solved.

Weiling, another new auto parts manufacturer, has solved the heating problem in extremely cold weather. Speaking of Weiling, maybe many friends in the automobile circle are no strangers. Weiling is a subsidiary of Midea Group, a domestic appliance head enterprise.

Last year, several auto parts announced by Weiling included automotive heat pump air conditioners.

At present, R134a(CH2FCF3, tetrafluoroethane) is usually used as the refrigerant for heat pump air conditioning, but when the outside temperature is low, the heating capacity is obviously attenuated. Therefore, there are explorations of mixed refrigerants in the industry, but the performance cannot be significantly improved.

The engineers of Weiling parts found another way, using carbon dioxide as refrigerant, and the heating efficiency was obviously improved at extremely cold temperatures.

Weiling’s rotary CO2 electric compressor can achieve a heating efficiency of COP=2 at -30℃. At the same time, the noise is low during operation and the overall design is lighter.

Engineer Weiling introduced that in extremely cold weather, users don’t need to "cover the quilt" to drive. At the same time, compared with traditional heat pump air conditioners, the heat pump with carbon dioxide as refrigerant can increase the cruising range of vehicles by up to 20%.

The CO2 electric compressor alone has 220 domestic invention patents and 14 international invention patents, and has completely independent intellectual property rights. At the same time, CO2, as a common greenhouse gas, is collected and used as a refrigerant, which also contributes to "carbon neutrality".

Last year, the heat pump air conditioning products of Midea Group Weiling components have been installed on pure electric brand vehicles such as Tucki and Weilai, which has become a microcosm of the rapid transformation of domestic component enterprises to electrification.

In 2020, Tesla put the heat pump air conditioner into a pure electric vehicle, which led the electric vehicle industry to take another step towards high efficiency. In just one year, by 2021, heat pump air conditioning has become the standard of high-end electric vehicles.

Obviously, the technology that will not be used in the era of fuel vehicles may be a huge innovation in the era of electric vehicles. In today’s increasingly fierce global competition for electric vehicles, there is still huge room for innovation in the field of electric vehicles.
