Not long ago, the State Council issued the Action Plan for Promoting Large-scale Equipment Renewal and Consumer Goods Trade-in (hereinafter referred to as the "Plan"), proposing key tasks such as carrying out trade-in of automobiles and household appliances and promoting trade-in of home-improvement consumer goods. According to the National Development and Reform Commission, this measure can not only promote technological upgrading of enterprises, improve production efficiency, but also guide residents to upgrade their consumption, realize energy saving and carbon reduction, and reduce potential safety hazards.

To implement a new round of trade-in of consumer goods, major manufacturers and platform enterprises have responded to this trillion-dollar huge market and launched promotional subsidies. What is the feedback from this wave of "more fashionable" markets? Where is the "new" in this round of trade-in? How can production and marketing enterprises and consumers seize the opportunity to achieve a win-win situation of high-quality development and high-quality life?

The home appliance market is moving from "is there" to "is it good"

On March 20th, in the store of Xinjiekou store in Suning.cn, Gao Rongping, a promoter, introduced in detail to Uncle Sun who was interested in buying air conditioners: "The first-class energy efficiency ratio of this Hisense bright air conditioner is as high as 5.28, which is fresh and silent, with a thickness of only 13.4 cm. The paint panel will not turn yellow and discolor after being used for a long time." Gao Rongping said that this air conditioner is currently heavily discounted. She calculated an account. "The market price of air conditioners is 5,099 yuan, which will go straight to 800 yuan during the event. The replacement of old machines at home can subsidize 600 yuan at the highest level, and the actual payment may be as low as 3,699 yuan."

"At present, upgraded products with large size, large capacity and multifunction are particularly popular. Since the launch of the trade-in activity, the sales growth rate of new energy-efficient air conditioners, large-capacity refrigerators and large-screen color TVs over 80 inches has exceeded 120%; Dishwasher sales increased by 103% year-on-year, and dryer sales doubled. " Wang Yisheng, the general manager of Suning.cn Xinjiekou Store, said that the 10 billion-yuan subsidy for trade-in will provide users with a large subsidy of up to 30%, which can be participated online and offline, and also provide services such as free door-to-door, disassembly and handling.

In Wuxi, the ongoing "Revitalization of Quality Life" activity of the 2024 Taihu Shopping Festival has launched a number of preferential policies to boost the release of large-scale consumer demand for household appliances. The maximum subsidy for replacing household appliances is 15%, and the maximum subsidy for a single household is 4,500 yuan. Consumers who purchase new green and energy-saving home appliances and new smart home appliances (the unit price is more than 500 yuan) in the event merchants can use China Unionpay Quick Pass APP payment code to reduce the turnover by 10%, and the maximum single subsidy is 1000 yuan. If the household appliances are trade-in, and the paid-in amount of each piece reaches 4,000 yuan, 6,000 yuan and 10,000 yuan, Wuxi Municipal Bureau of Commerce will give consumers 200 yuan, 300 yuan and 500 yuan extra incentives for trade-in.

The promotion of car companies is also in full swing. BYD launched the activity of "Old Friends Rejuvenating the New Season". During the activity, car owners can get a replacement subsidy of up to 8,000 yuan when they replace BYD’s new energy vehicles in the store, and a new car gift package worth 3,888 yuan. Dongfeng Motor’s trade-in action covers more than 50 models, and the replacement subsidy is expected to exceed 10 billion yuan; FAW-Volkswagen introduced the old car replacement down payment policy …

"In fact," trade-in "is nothing new. As early as 2009, the state launched a combination of" home appliances going to the countryside "and" trade-in ",and enterprises cooperated with the government to implement subsidy policies to recycle and sell services, initially forming an operation mode of trade-in; Since 2016, home appliance sales companies have joined hands with manufacturers to organize their own trade-in activities, subsidize consumers, and develop their own trade-in sales system. " Qian Zhengming, secretary of the Party branch of the Provincial Household Electrical Appliances Association, said.

With the comprehensive popularization of durable consumer goods in China, the demand for upgrading the stock of consumer goods is constantly increasing, and the consumer market is changing from "whether there is" to "whether it is good". According to reports, the home appliance market in Jiangsu Province has accounted for about 10% of the national market over the years, among which it is estimated that there are more than 30 million home appliances in extended service, which has great demand and potential for upgrading. Qian Zhengming believes that the trade-in action will not only enable consumers to enjoy more convenient services and more favorable prices, but also promote the high-end, intelligent and green development of the manufacturing industry. For the society, it will also help to eliminate old household appliances and eliminate security risks.

Let "unwilling to change" and "afraid to change" become "comfortable to change"

I don’t know who to look for to disassemble the toilet, and I want to buy a dishwasher, but there is no reserved position in the kitchen, and the discarded old mattress waste station is not needed … As the real estate industry enters the era of stock, the renovation of old houses has gradually become the main force in the home industry. However, as a kind of low-frequency consumer goods, consumers will not only think twice when buying furniture, but also the disposal of waste furniture often makes people feel quite tricky.

"The biggest problem in this industry is the long consumption decision-making cycle and low conversion efficiency." Bai Yang, the head of Shilin Home Furnishing Division, said that unlike home appliances, automobiles and other industries, the replacement of furniture faces the problems of "difficult handling, difficult handling and low added value of recycling", which makes it difficult for customers to make choices and make decisions.

How to shorten the consumer decision-making cycle? "In addition to providing sufficient discounts in shopping malls, providing convenience services in residential quarters has become an important means to capture service information and increase user stickiness. For example, free recycling of used mattresses, provision of toilet disassembly services, design and local reform of cabinets and balconies … The core is to let consumers see how the service is done and feel the changes in consumption concepts, thus solving the pain points that customers are afraid to change, unwilling to change, and do not know how to change. " Bai Yang said that by integrating merchants to build solutions, the company has now settled in 25 communities and served nearly 1,000 families.

From 2021 to 2023, about 220,000 pieces of household appliances were recycled in Suning.cn, and a total of 19.9 million yuan of old machine residual value subsidies and new machine subsidies were distributed. The proportion of old-for-new appliances was about 3.1%, and there was still much room. In the same period, JD.COM Wuxing recycled 8573 old household appliances, showing a trend of small total and high growth rate. According to statistics, from 2021 to 2023, the household appliance recycling enterprises in Nanjing recycled 3.164 million sets of "four machines and one brain" (TV sets, refrigerators, washing machines, air conditioners and microcomputers).

"At present, the trade-in of home appliances is independently carried out by manufacturers, and the government’s blessing is needed in terms of subsidies and credibility. At the same time, it is necessary to increase publicity, change consumers’ awareness of "home appliances are not broken and not replaced", and help consumers realize the harm of home appliances that are over-aged. In addition, the original definition of trade-in commodities is less, and there are not many participating enterprises. It is necessary to expand the categories and expand the scope of trade-in participating enterprises. " Qian Zhengming suggested.

At present, the automobile consumption demand in the whole province and even the whole country has entered a period of steady development, and the activities of car subsidies are carried out separately in various places, which are more to attract the consumption power of cities with low policy activities and cannot drive new demand.

In this regard, Zhao Qiang, director of the Wuxi Municipal Bureau of Commerce, said that in addition to subsidizing individual consumers who scrap or transfer non-operating passenger cars under their personal names and buy new cars, they will also explore ways to promote the upgrading and expansion of the automobile aftermarket and promote the integrated development of automobile maintenance, cultural experience, professional competitions, vehicle modification and consumer finance. In addition, encourage the transformation from "brokerage" to "distribution", improve the comprehensive management and supporting service functions of the used car market, and encourage qualified enterprises to make full use of various trade promotion platforms to broaden overseas market channels.

Recycle and make good use of misplaced resources.

The "Program" requires the implementation of recycling actions. Improve the recycling network of waste products and equipment, support the circulation and trading of second-hand goods, promote remanufacturing and step-by-step utilization in an orderly manner, and promote the high-level recycling of resources.

On the disassembly assembly line of Nanjing Kaiyan Electronics Co., Ltd., an average ordinary refrigerator produces about 0.4 kg of copper, 0.8 kg of aluminum, 17 kg of iron and 7 kg of plastic after disassembly procedures. Song Guoping, the company’s administrative director, said that the company’s refrigerator line disassembly processing capacity can reach 1,000 units per day, and the annual processing capacity of "four machines and one brain" reaches 1.93 million units. "These renewable resources after resource and harmless treatment have greatly reduced the mining of copper mines and iron mines, reducing carbon emissions and turning waste into treasure."

"Scrapped motor vehicles are a collection of steel, aluminum, rubber, plastics, glass and various non-ferrous metals. If they are dismantled by themselves or by illegal and irregular enterprises, a large number of rubber, plastics and glass will be abandoned and burned, which will seriously pollute the ecological environment. In addition, illegal dismantling of scrapped motor vehicles, vehicle transactions and cross-regional transfer will pose great security risks to road traffic. " Li Zheng, general manager of Nanjing Coson Ning Environmental Protection Technology Co., Ltd. said that scrapped motor vehicles must be disposed of in accordance with the Law on the Prevention and Control of Environmental Pollution by Solid Wastes, and it is suggested that they be scrapped in the vehicle registration area and managed locally.

"At present, China is at the peak of household appliances scrapping. However, at present, enterprises are carrying out the" trade-in "activity, and most of the recycled waste household appliances, except air conditioners, have nowhere to be accepted and piled up in the open air, causing environmental pollution. Some of them flow to the second-hand market and illegal dismantling channels. Even if they enter the formal dismantling enterprises, they have gone through many links, and the expenses are high, so the enterprises lack enthusiasm for operating at a loss. In addition, the’ illegal dismantling’ of used household appliances has no environmental protection disposal facilities, and there is no actual tax payment at the recycling end and the sales end, and the operating cost is low, which directly leads to the lack of competitive advantage in the price of formal dismantling enterprises, resulting in bad money expelling good money. " Qian Zhengming said.

Sun Bo, Secretary-General of Nanjing Renewable Resources Association, said that the recycled waste materials should not just be scrapped, but must enter the formal recycling and dismantling enterprises, and then enter the remanufacturing process, so as to realize the goal of turning old materials into new ones and turning waste into treasure.

The reporter learned from the Nanjing Municipal Bureau of Commerce that this year, we will speed up the cultivation of home appliance recycling and dismantling industries, standardize and rectify the circulation order of second-hand home appliances, and strictly prohibit the illegal renovation and disassembly of three-no products from entering the consumer market. Accelerate the development of "replacement+recycling" logistics system and new model, support household appliance production and sales enterprises to build reverse logistics system through distribution, installation, maintenance and other channels, or cooperate with professional recycling enterprises to recycle waste household appliances at home. Explore the formulation of local standards or industry standards for the service life and scrapping conditions of different types of household appliances, and relax the qualification control of household appliance production and sales enterprises applying for electronic and electrical products processing. At the same time, encourage capable dismantling enterprises to expand home appliance recycling business to the front end, and encourage the construction of recycling network system.

Recent studies have found that chronic obstructive pulmonary disease (COPD) is one of the significant factors that affect the death of patients in COVID-19. Among the dead people in COVID-19, the proportion of patients with chronic obstructive pulmonary disease is 6%, but only 1% among the surviving people. In addition, although patients with chronic obstructive pulmonary disease may not be more likely to be infected with Covid-19, they are more likely to die when they are infected.

What is chronic obstructive pulmonary disease? Chronic obstructive pulmonary disease (COPD) is a chronic bronchitis and/or emphysema characterized by airflow obstruction, which can further develop into chronic diseases of cor pulmonale and respiratory failure. Different from common chronic diseases such as hypertension and diabetes, chronic obstructive pulmonary disease is often not well known.

1. The prevalence rate of COPD in men over 70 years old is nearly 50%, and the difference between male and female is nearly 1 time.

According to the latest China Lung Health Survey (CPH2018), among 50,991 people surveyed from June 2012 to May 2015, the prevalence rate of COPD was 8.6%. Based on this, it is estimated that about 99,900 million people in Chinese suffer from COPD. The prevalence rate of COPD increases with age. The prevalence rate of people over 40 years old is significantly higher than that of people aged 20-39. The prevalence rate of COPD in men over 70 years old is nearly 50%. At the same time, the prevalence rate of men in all age groups is higher than that of women, and the prevalence rate of men over 30 years old is more than twice that of women.

　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 Figure 1: Prevalence of COPD in different gender and age groups.

2. Smoking is the main risk factor, and air pollution is the main risk factor for non-smokers to get sick.

CPH2018 also made a statistical analysis of possible risk factors of COPD, including smoking, air quality, BMI, family history, education, etc. The results showed that smoking, air pollution, low BMI and parents’ history of respiratory diseases were all risk factors of COPD, among which smoking and air pollution were the main risk factors.

　 　 　 　 　 　 　 　 　 　 　 　 　Figure 2: odds ratio (OR) of 2：COPD risk factors

Note: odds ratio (OR, Odds ratio) is the ratio of the exposed and unexposed people in the case group divided by the ratio of the exposed and unexposed people in the control group. Greater than 1 indicates that this factor is a risk factor, less than 1 indicates that this factor is a protective factor, and equal to 1 indicates that this factor does not work.

The analysis also shows that smoking history has a significant impact on the overall prevalence of COPD, and the prevalence of COPD increases with the increase of smoking years. Air pollution has no significant effect on the prevalence of COPD in the whole population, but it has a significant effect on non-smoking groups. The more serious air pollution is, the higher the prevalence of COPD is.

　 　 　 　 　 　 Figure 3: Smoking history and COPD prevalence Figure 4: Smoking years and COPD prevalence.

　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　Figure 5: Air quality and COPD prevalence rate

The Prospective Research Project of Chronic Diseases in China also published a survey of 280,000 non-smoking adults in China in 2019. The results show that using solid fuel is an important risk factor for major respiratory diseases, and switching to clean fuel such as natural gas can reduce the risk. Because chronic obstructive pulmonary disease is related to the concentration of sulfur dioxide and carbon monoxide, people who are engaged in jobs with dust environment, such as teachers and coal miners, are also prone to COPD.

3. The prevalence rate of people over 40 years old is different in different regions, with the highest in southwest China (20.2%) and the lowest in central China (10.2%).

The research conducted by China Center for Disease Control and Prevention on 66,752 people in 2014-2015 found that the prevalence rate of COPD over 40 years old also showed obvious differences in different regions, with the highest prevalence rate in southwest China (20.2%) and the lowest in central China (10.2%).

　 　 　 　 　 　 　 　 　 　 　 　 Figure 6: Prevalence rate of COPD among people over 40 years old in different regions.

4. Up to 56% of COPD patients may have cognitive impairment.

A large number of neuropsychological tests suggest that up to 56% patients may have cognitive impairment. The Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD)2021 also pointed out that cognitive impairment is common in COPD patients, and the prevalence and severity vary according to the evaluation type, with an average prevalence of about 32%. Moreover, cognitive impairment will aggravate the health problems of COPD patients. Compared with patients with single disease, patients with cognitive impairment and COPD have a higher respiratory-related hospitalization rate of 48% and a higher mortality rate of 3 times. Therefore, it is particularly necessary to help patients with complications to carry out effective self-management.

In addition, cardiovascular disease, osteoporosis, depression/anxiety are also common and important complications of COPD.

5. The mortality rate of COPD has decreased obviously year by year, but it is still high compared with other developed countries.

The mortality rate of COPD in China decreased from 99/100,000 in 1990 to 68/100,000 in 2017, and the mortality rate of standardized age decreased by 68.6%. Although the mortality rate in China is decreasing year by year, it is still at a high level compared with other developed countries (see the figure below).

　 　 　 　 　 　 　 　 　 　 　 　Figure 7: Mortality rate of male COPD patients aged 50-74 in countries around the world.

6. The diagnosis rate is lower than 30%, and the proportion of hospitalization is lower than that of outpatient treatment.

The diagnostic rate of COPD in China is between 23.61% and 30.00%, which shows that the diagnostic rate of COPD in China is low and the missed diagnosis and misdiagnosis are serious. On the one hand, COPD is asymptomatic in the early stage. In epidemiological screening, more than 70% of patients (I~II stage) have little or no symptoms, and even if they have symptoms, they just cough and expectoration, which has not attracted the attention of patients. On the other hand, due to the cost of examination and technical operation, lung function examination, as a gold standard for the diagnosis of COPD, has not been popularized in many hospitals (especially in primary hospitals), resulting in many patients not being diagnosed with COPD in time and delaying treatment.

　 　 　 　 　 　 　Table 1: COPD pulmonary function staging (GOLD staging) [After inhaling bronchodilator]

In addition, the diagnosis and treatment of COPD in China is also more severe. The conventional treatment rate of COPD patients is only 7.9%, and 84% of patients with stage ⅱ and above have not received treatment. The proportion of COPD patients receiving outpatient treatment is about 50%, while the proportion receiving hospitalization is only between 8.78% and 35.60%.

7. The average medical expenses of COPD ranged from 5,000 yuan to 16,000 yuan.

At present, no scholars have studied the medical expenses of COPD patients nationwide, and most of the research on COPD expenses is limited to local or regional areas.

A study on the medical expenses of COPD patients in Ningbo, Zhejiang Province found that from October 2012 to October 2013, the hospitalization expenses of male patients and female patients are shown in the following table. Among them, the average total hospitalization expense for men is 16,000 yuan, while that for women is 14,500 yuan, and only about 30% is borne by individuals.

　 　 　 　 　 　 　 　 　 　 　 　 　 　 Table 2: Hospitalization expenses of COPD patients in Ningbo, Zhejiang Province

In recent years, because the prevalence rate in southwest China is higher than that in other regions, many scholars have begun to choose southwest China to study the treatment cost of COPD patients. The following table is part of the research results, from which we can find that the overall cost of the western region is low, and the average hospitalization cost does not exceed 10 thousand yuan. In addition, according to the survey data of Sichuan province, the cost of western medicine accounts for the highest proportion, accounting for 38.32%, followed by the cost of diagnosis, accounting for 24.41%.

　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　Table 3: Hospitalization expenses of COPD patients in western China　

8. About 58% of commonly used drugs for COPD have been included in the medical insurance catalogue.

COPD can be divided into stable stage and acute exacerbation stage according to the progress of the disease course. In the stable stage, the symptoms such as cough and shortness of breath are stable or mild, while in the acute exacerbation stage, the respiratory symptoms that lead to additional treatment are seriously aggravated, and the patients’ cough and wheezing are aggravated, or may be accompanied by fever and other inflammatory manifestations. Drug therapy is a common treatment for COPD. GOLD2021 edition points out that drug therapy can alleviate COPD symptoms and reduce the frequency and severity of acute exacerbation. At present, there are data showing that drug therapy can reduce mortality. It is worth noting that COPD patients need to take drugs for a long time, mainly inhaled drugs, supplemented by oral drugs. With the progress of COPD, the therapeutic drugs and management methods used have been adjusted.

Imagine that there is a virus lurking in your body, which quietly ambushes and waits for an opportunity to make you "miserable". More than 90% of adults will carry this virus, which is ready to attack at any time, but we often don’t know it …

This virus is the varicella-zoster virus that causes herpes zoster.

Once infected, carry it for life!

After the first infection, about 70% people will have symptoms of chickenpox, while 30% people will not get sick and become recessive infection. The virus is quietly lurking in the "neurons of the spinal dorsal root ganglion". Terrible is, regardless of symptoms, this virus will be carried for life, and may be activated at any time due to decreased immunity, thus causing herpes zoster.

The pain during the attack is unimaginable.

The pain of herpes zoster can reach ten levels, which has reached the highest level among the most commonly used pain levels at present! At the time of attack, there are various forms of neuralgia, including knife-like, acupuncture-like and burning-like pain, which usually intensifies at night, making it difficult for people to sleep. What’s more, even if the herpes is cured, there may be a long-term neuralgia. According to statistics, about 9%~34% patients with herpes zoster will suffer from this kind of torture, and the pain may last for more than one year, or even as long as 10 years or more.

Treatment within 72 hours is crucial.

Although herpes zoster is a self-limiting disease, most people will heal themselves in about two or three weeks. However, the golden period of herpes zoster treatment is 72 hours! Receiving antiviral treatment in time within 24~72 hours after the appearance of rash can not only effectively control pain, accelerate the healing of rash, but also reduce the risk of post-traumatic neuralgia. Especially when the lesions occur in the head and face, immediate treatment is needed to avoid serious complications.

Who is more likely to be the "target" of herpes zoster?

Epidemiological data show that about one third of adults will suffer from herpes zoster once or more in their lifetime.

Especially the following five high-risk groups, we should be more vigilant:

1. Middle-aged and elderly people over 50 years old: With the increase of age, human immunity gradually declines, and the resistance to varicella-zoster virus weakens. In addition, the risk of herpes zoster in women is relatively higher.

2. Patients with immune system diseases: such as cancer patients, patients with lupus erythematosus, AIDS-infected people, etc., are more prone to herpes zoster due to low immune function.

3. Patients with chronic diseases: such as diabetes, chronic obstructive pulmonary disease, cardiovascular disease, chronic kidney disease, asthma and other chronic diseases, their risk of herpes zoster is also significantly increased.

4. Sub-healthy people: Long-term staying up late, improper diet, sedentary and other bad habits lead to decreased immunity, making this group of people more susceptible to infection.

5. People who regularly take hormones: Hormones will inhibit immune function, and excessive dependence on hormones may even lead to the disappearance of immunity, thus increasing the risk of herpes zoster.

How to prevent herpes zoster?

1. Vaccination: the most effective protection

The data show that within 3 years after vaccination with herpes zoster vaccine, the protective effect on adults aged 50-59 is as high as 96.6%. Therefore, people over 50 years old and people who have suffered from herpes zoster twice or more should be actively vaccinated.

2. Improve immunity

Regular work and rest: It is recommended to fall asleep before 23 o’clock every night, ensure 7-9 hours of sleep, and improve immune cell activity.

Balanced diet: eat more than 12 different kinds of food every day, not less than 25 kinds every week to ensure adequate nutrition; It is recommended to eat more fresh vegetables and fruits, whole grains and potatoes, and supplement probiotics.

Appropriate exercise: It is recommended to carry out moderate-intensity aerobic exercise for 30~45 minutes five times a week, such as jogging, cycling, yoga, etc., to enhance physical fitness.

Step 3 avoid contact

Although herpes zoster is not contagious, close contact with patients should be avoided, especially touching herpes fluid. When there are patients with herpes zoster at home, isolation measures should be taken. At the same time, pay attention to daily disinfection and indoor ventilation to reduce the chance of virus transmission.

To sum up, varicella-zoster virus is hidden in more than 90% adults, and once infected, it will be carried for life. Herpes zoster has a strong pain and may be accompanied by postherpetic neuralgia, so it should be treated with antiviral therapy in time. High-risk groups need to be vigilant, and herpes zoster can be prevented by vaccination, improving immunity and avoiding contact with patients.

That’s the headline of Dr. Zeqiao’s health. See you tomorrow!

　　On May 2, local time, Tesla announced that it would refinance US$ 2 billion, including the newly issued US$ 650 million common shares (about 2.7 million shares) and US$ 1.35 billion convertible bonds, to maintain the overall operation of the company.

　　Financing is like "tearing off a band-aid"

　　Tesla CEO Musk said at the investor conference that although Tesla currently has enough cash flow to support its business development, having more cash will help Tesla to buffer in order to cope with the unexpected macroeconomic situation and the potential demand headwinds in the automobile market.

　　Musk was finally willing to "plan ahead" to face the reality, and also let investors worried about Tesla’s tight cash flow breathe a sigh of relief. Dan Ives, managing director of the asset research department of Wedbush Securities, a wall street brokerage, believes that Tesla’s financing decision is like "tearing off a band-aid". He said: "Tesla is finally willing to listen to investors. Before, the market was worried that Tesla might not have enough cash to support it through the second quarter. The data can tell everything."

　　In this round of financing, Musk said that he would buy Tesla shares worth $10 million (about 41,896 shares). According to InsiderScore, Musk’s move to buy back shares implies that the market can buy Tesla shares in the short term. In the three months after Musk’s five purchases, Tesla’s share price rose by more than 40% on average.

　　In addition, the new documents show that Musk personally owes more than $500 million in loans to investment banks. According to Tesla’s latest submission, Musk personally owed $213 million, $209 million and $85 million to Wall Street investment banks Goldman Sachs, Morgan Stanley and Bank of America, respectively, but this was $117 million less than that of the same period last year. Last year, Musk personally owed $624 million to investment banks.

　　Musk holds about 20% of Tesla’s shares, with a total value of 8 billion to 12.6 billion US dollars. Tesla warned that if the stock price continues to fall and the bank forces Musk to sell some of its shares, it may in turn put new pressure on the stock price.

　　It is worth noting that the primary participants in Tesla’s new financing plan, including Goldman Sachs and Citigroup, have all given Tesla shares a "sell" rating, which is relatively rare on Wall Street.

　　The market value should reach 500 billion dollars.

　　After Tesla announced a $2 billion financing plan, its share price rose by 4%. However, this year, Tesla’s share price has fallen by nearly 30%, with a market value of $42 billion. Musk also told investors recently that autonomous driving will make Tesla a company with a market value of more than 500 billion US dollars.

　　This means that Tesla’s market value will be more than 10 times on the current basis. According to Musk, Tesla will become a "value-preserved" model. He expects that the value of each Tesla will be between 150,000 and 250,000 US dollars in three years, thanks to the upgrade of Tesla’s autopilot software. He also predicted that there will be 1 million autonomous Robotaxis on the road next year.

　　However, Musk’s confidence has also been doubted by analysts. For example, Jeffrey Osborne, an analyst at Cowen, a Wall Street investment bank, wrote in a letter to investors: "We believe that the transformation of Tesla’s technology and execution strategy will face great risks. If Tesla wants to compete with NVIDIA in hardware, Google Waymo in software, and the shared taxi platform that is dominant in the current market in the operation of self-driving taxis, it is very difficult to achieve."

　　Osborne also pointed out that Tesla did not fully plan how to operate self-driving taxis, because some basic questions have not been answered, such as pricing, insurance liability and legal supervision. Musk said after the earnings conference last month that Tesla is considering launching its own insurance financial products.

　　Zach Kirkhron, Tesla’s newly appointed CFO, maintained his expectations for the company’s prospects at the investor conference, that is, 90,000 to 100,000 Tesla vehicles were delivered in the second quarter and 360,000 to 400,000 Tesla vehicles were delivered throughout the year.

Do you know Google trends? If you are doing overseas business, you should have heard about it. Google Trends can help you analyze your competitors, understand the hot news of various countries and analyze market segments.

Google is the largest search engine in the world, and there are more than billions of information and data searched by Google every day. Google Trend is its product. Through Google Trend, you can get related keyword popularity and trends from all over the world and so on. Here are some usages of Google Trend, so you can learn it quickly if you are in an overseas market.

1. View the latest hot search

When you open the Google Trends website, you can see that there is a popular section in the upper left corner, which is the hottest topic in every country at the moment, arranged from top to bottom according to the highest heat.

Different countries have different topics. You can choose the corresponding countries according to the market you have made to check the hot topics. Combining hot topics can help you understand what users are concerned about now, and then combine them to provide ideas for your social media update.

Generally speaking, this section is more suitable for those blog forums or technology websites that output articles, because writing articles must keep up with current events. Of course, if you are a seller, you can also pay attention to whether there are popular products through popular search. For example, if there is a hot topic in cycling season, and you sell bicycles, then you can consider whether to increase the promotion.

Step 2 analyze competitors

Google Trends can search for keywords, such as brand name or product model, and customize the time range to view its hot trends. You can check the trend of competitors’ popularity by entering their brand names or competing products. If the popularity of your competitors suddenly soars or continues to surpass yours in a certain period of time, then you should analyze what happened during that period, whether your competitors made strategic adjustments, etc., and how you can make your own adjustments to this point.

Take Xiaomi SU7 as an example. On March 34, 2024, Xiaomi SU7 held a press conference and was officially delivered on April 3. We input Xiaomi SU7 into Google Trend, and we can see that its popularity has a rapid growth trend from March 17th to April 6th, 2024.

Image source: trends.google.com

The reason for this obvious peak must be the release, listing and delivery of the new car. At that time, Xiaomi SU7 really caused a very heated discussion, and the search for SU7 on the Internet also increased significantly. Similarly, if you want to search for other competing products, you can also search in this way.

In addition to directly searching for competitors’ keywords, you can also enter your own brand or product for comparison at the same time. Google Trends will simultaneously give a comparison chart of the heat of two competing products, which can visually see how the competition between them is in each time period, and also help sellers to analyze whether there are problems in their marketing strategies.

3. Judge whether it is a seasonal product.

Some products with special properties are seasonal products, such as Mother’s Day gifts, Christmas gifts, hand warmers, etc., which cannot be "resident" products because of their unique attributes. We can also judge these products by using Google Trends.

For example, when searching for Christmas gifts, we can see that there is an obvious peak in the trend from mid-December to Christmas Eve, and the search volume in the rest of the time is almost zero, which is a very obvious seasonal trend.

There are also some products whose seasonality is not particularly obvious that we need to search and judge through Google Trends, such as sunglasses. Most people will think that sunglasses are more needed in summer when the sun is strong, but in fact, through search, we can see that sunglasses have peaked in most time periods of the year, which is convenient for sunglasses sellers to find the right time and increase their promotion efforts.

4. Analyze market segments

By analyzing market segments, it helps sellers to find the target market more accurately and launch marketing planning for the target market. I can give an example of Google trends with laptop as the key word.

Search for laptop in the past 90 days in the United States, and the top five in terms of search popularity are New York, Washington, Virginia, Columbia, and Texas.

Through the inquiry of each region, we can see that New York State mentions Lenovo brand more, and Virginia mentions HP more. This will help merchants to make targeted marketing strategies according to the degree of brand preference of each state, and the user market will be more accurate, which is very beneficial to sales.

5. Find accurate keywords

Like e-commerce platforms such as Amazon, the keywords of products are very important for your ranking in search engines, and only when you use the right keywords can you get ahead.

There are many paid keyword research tools on the Internet, but we can use Google Trends, a free tool, to query keywords, so as to determine what keywords are more accurate.

Let’s take laptop as an example. When we search laptop and laptop computer at the same time, we can see that the interest index of laptop is much higher than laptop computer, which shows that the word laptop is more accurate.

Image source: trends.google.com

In addition, by looking at the related query section below, we can see the hot topics related to the searched keywords, such as "shop luggage" and "snapdragon x elite laptop", which will help businesses find some potential customer needs.

6. Optimize Google shopping strategy

Google Shopping Advertising is also a very important promotion strategy for businesses that make sea brands. In addition to the functions mentioned above, Google Trend can also search Google Shopping Data, just switch.

We use glove as the key word to search, and we can see that in the past five years, the sales volume of glove has obviously increased in June every year, and then it has shown a downward trend. For merchants, according to the data given by Google Trends, they can make preparations in advance when the peak season is coming, so as not to be in a hurry to catch up with the progress during the activity period.

These are the six usages of Google trends to be introduced today, and those that have not been introduced are welcome to discuss in the comments section.

There seems to be no connection between the first two news items and the last one, but if you have heard the ins and outs of Taiwan Province’s Pinyin War, you may have some new knowledge about the origin between Taiwan Province and Chinese Pinyin.

Anyone who has been to Taiwan Province, or is familiar with Taiwan Province, knows that there are many pinyin systems in Taiwan Province, which are different from those in mainland China. The function of phonetic notation for Chinese characters is undertaken by phonetic symbols (that is, the system that looks a bit like Japanese katakana). The romanization of Chinese characters, Chinese Pinyin and Universal Pinyin are competing for who will undertake the function of Latin Chinese characters (that is, spelling Chinese characters with Latin letters). In particular, the contest between the latter two went beyond the linguistic category and rose to a political struggle, which caused widespread concern and heated discussion, so it was called "Pinyin War".

We are all familiar with Chinese Pinyin, so I won’t say much here. The Romance of Mandarin comes from the French Pinyin of Romance of Mandarin (commonly known as "Lao Guo Luo") formulated by the Preparatory Meeting for the Unification of Mandarin in 1926, and the compilers brought together many famous linguists such as Qian Xuantong, li jinxi, Zhao Yuanren and Lin Yutang. In 1928, Nanjing Kuomintang Government College published it as "Mandarin Phonetic Alphabet II", which was implemented simultaneously with phonetic alphabet. In 1986, Taiwan Province released the Second Form of Phonetic Symbols in Mandarin, commonly known as "New Country Luo". The universal pinyin scheme was first put forward in 1997 and was first used in Taipei City where Chen Shui-bian was the mayor in 1998. In 2002, the Ministry of Education of Taiwan Province adopted the "Chinese Pinyin System as Universal Pinyin", and replaced Chinese Pinyin with Universal Pinyin.

To tell the truth, Mandarin Roman and Universal Pinyin look similar to Chinese Pinyin, both of which use Latin letters, but there are differences in handling some problems, such as which letter to use to express some pronunciations, whether to add additional symbols, how to express Chinese tones, etc. For example, there is a Mucha area in Taipei, which is spelled "Muzha" in Chinese pinyin, "Mucha" in Roman characters and "Mujha" in common pinyin. Generally speaking, all countries or regions want to promote a standard spelling scheme, but different spellings often coexist in Taiwan Province for a long time.

The coexistence of various spelling schemes of Chinese characters is actually the result of political wrestling in Taiwan Province. Before the Chinese Pinyin Scheme was launched in mainland China in 1958, there were always many Latin schemes for Chinese characters in the Chinese character circle. However, after 1958, the spelling in mainland China was unified as Chinese Pinyin, while Taiwan Province, on the other side of the Taiwan Strait, still insisted on using Roman characters, the national language.

Even in Chinese Pinyin, which has been adopted by the United Nations Secretariat since 1979, it is used to transliterate the names and places of China in various Latin alphabets; Even though the International Organization for Standardization (ISO) stipulated in 1982 that Chinese Pinyin should be the international standard (ISO7098), Taiwan Province still used Roman characters to spell Chinese characters, and even released a set of "New Country Luo" which few people used. The competition between Roman characters in Mandarin and Chinese Pinyin may be regarded as a prelude to the Pinyin War.

About because Chinese Pinyin has gained more and more international recognition, due to the need of exchange of scientific, technological, cultural and academic materials, and in order to be in line with the world, in 1999, the administrative department of Taiwan Province authorities decided to adopt the Chinese Pinyin method in mainland China, and it was planned to make Chinese Pinyin a compulsory course for primary school students two years later.

If the story ends here, then the "Pinyin War" is also strangled in the cradle. It happened that in 2000, Chen Shui-bian came to power, implemented the "Taiwan independence" policy, and constantly "localized" and "de-China" in culture. In this context, the universal pinyin, which claims to be more suitable for spelling "Taiwanese Mandarin", has replaced the Chinese pinyin.

Such a move was fiercely criticized and resisted by all sides of the island, and the "Pinyin War" broke out. The main argument of the opponents in the debate is that the universal pinyin is not universal at all, and even it is difficult to pass in Taiwan Province, let alone meet the international standards. Although the official said that universal pinyin would not be enforced, counties and cities that can adopt "universal pinyin" can apply for huge subsidies, while those that adopt Chinese pinyin have no preferential policies. Despite this, some counties and cities do not buy it. For example, Taipei City, which once took the lead in universal Pinyin, insisted on using Chinese Pinyin.

Although the degree of cooperation among all parts of the island is not high, and the backlash from all walks of life has never been cut off, Taiwan Province officials have never given up their efforts to make universal pinyin "unify the world", and even prepared to make all place names adopt universal pinyin by the end of 2007. However, the situation suddenly changed in 2008, when Ma Ying-jeou became the leader of Taiwan Province region. On September 16th, the Ministry of Education of Taiwan Province decided to completely abandon the common pinyin and switch to the Chinese pinyin which is common with the mainland. The "Pinyin War" that lasted for many years finally came to an end.

Of course, although the war is over, there are still many battlefields to be cleaned. For example, in the past six years, the promotion of universal pinyin has left a lot of signboards, and it is naturally a large expenditure to replace them all. Therefore, it is inevitable that the two schemes will coexist for a long time.

Whether to use Chinese Pinyin or Universal Pinyin is originally just a linguistic question. It is not difficult to get an answer by comparing which scheme is more systematic, which scheme can accurately record and reflect Chinese pronunciation, which scheme is easier to teach and which scheme is more in line with international standards. In fact, Chinese pinyin and universal pinyin are roughly the same, with only a few differences. Linguists and users have their own judgment on which of the two schemes is better or worse. However, when Universal Pinyin was implemented, the two parties, the state and the pro-China, also criticized the Democratic Progressive Party authorities for "politics trumps professionalism and ideology overturns practicality". It is no wonder that when the relevant authorities in Taiwan Province decided to change the Chinese transliteration policy from "Universal Pinyin" to "Chinese Pinyin", the People’s Daily at that time was accompanied by an eight-word commentary: "A pragmatic move".

From the perspective of economic, social and urban development, one of the important backgrounds of the transformation of old urban communities is that China’s urbanization has entered the second half. In 2019, China’s urbanization rate has reached 60.60%, and the per capita GDP has exceeded 10,000 US dollars, which is higher than the average level of upper-middle-income countries. The process of urbanization in China has entered between the second turning point (urbanization rate is 50%) and the third turning point (urbanization rate is 70%), and the urban development has shifted from incremental expansion to the era of upgrading stocks. Urban governance needs to pay special attention to people’s livelihood issues and promote urban transformation and development.

The city is a living body, and urban renewal is an eternal topic. The renovation of old residential areas embodies the development idea of "making people more convenient, more comfortable and better in urban life". As early as the central city work conference held in 2015, the central government has proposed to speed up the transformation of old communities. The the Political Bureau of the Communist Party of China (CPC) Central Committee Conference held in July 2019 proposed to implement short-board projects such as the renovation of old urban communities, urban parking lots and the construction of urban and rural cold chain logistics facilities. The renovation of old residential areas has been accelerated.

According to the deployment, in 2020, the country plans to renovate 39,000 old urban communities, involving nearly 7 million residents, double the number in 2019, with the focus on residential areas completed before the end of 2000. This work has also become a new starting point for "stable investment" in urban and rural construction after the investment in shantytown renovation. The renovation of old residential areas can not only promote the organic renewal of the city, improve and upgrade the living environment of residents, but also create new investment and jobs, which is also of great significance to the current work of "six stabilities" and the implementation of "six guarantees".

At present, the year 2000 is generally used as the node to divide old communities and new communities. The residential quarters built before the end of 2000 generally have the demographic characteristics of "prominent aging phenomenon", the location characteristics of "adjacent to the old city center", the architectural entity characteristics of "five or six floors without elevators" and the social governance characteristics of "lack of property management". Therefore, there are housing safety problems, infrastructure problems, supporting services problems and community management problems in old residential areas that need to be solved.

Old residential areas have universal characteristics, and the reconstruction work needs to start with these universal characteristics and summarize the possible problems. The author believes that there are six main problems in the renovation of old residential areas: first, in community governance, residents’ cognition and demands for the renovation and upgrading of residential areas are different and difficult to coordinate; Second, in terms of updating hardware facilities, community supporting facilities are old, some facilities are lacking in functions, and some facilities even have hidden dangers; Third, the construction of public service facilities, land shortage and difficult to supplement; Fourth, in terms of standards and norms, relevant norms need to be further established and improved; Fifth, in the aspect of fund-raising, it is necessary to establish a fund mechanism that is reasonably shared by multiple subjects; Sixth, in terms of institutional mechanisms, relevant approvals need to strengthen coordination and cooperation.

The renovation of old residential areas needs system design, and the goal of "five modernizations" is clear: First, it is suitable for aging, including barrier-free design and installation of elevators; Second, greening, energy saving and consumption reduction, and integration with urban green development; Third, communization, promoting the leadership of party building and residents’ autonomy, and developing smart communities in governance; Fourth, the circle of life, including "15-minute life circle", "10-minute old people circle" and "5-minute children circle" and the construction of public charging piles and public laundry rooms; The fifth is human culture, which combines the transformation of old residential areas with the protection of local characteristics and the continuation of urban cultural context to promote urban organic renewal.

The renovation of old residential areas needs comprehensive planning, and the renovation objects and tasks can be classified. The renovation of old residential areas includes the following aspects: first, the renovation of single buildings to make them more solid and beautiful; The second is the transformation of residential environment, which makes residents’ life more quality; Third, all kinds of facilities are perfect, making residents’ lives more convenient; Fourth, the community management is perfect, which makes the community life more orderly.

According to this, the task of old residential area renovation can be divided into three categories: first, the basic category to meet the needs of safety and basic life, including municipal supporting infrastructure such as water, electricity and heating roads, and maintenance of public parts of buildings; The second is the improvement of life and convenience, including the improvement of residential environment and supporting facilities, the installation of elevators and the increase of parking facilities in conditional residential areas; The third is to improve the quality, which can be provided by the market, including the supply of community public service products, such as pension, nursery, health, etc. The provision of such public services must be based on the principle of adapting to local conditions and seeking truth from facts, and strive to provide residents with "menu-style" optional services.

The transformation of old residential areas needs the participation of social capital and the promotion of multi-subject and multi-source power. The executive meeting of the State Council held on April 14th this year proposed to establish a mechanism for the government, residents and social forces to share the reconstruction funds reasonably, with subsidies from the central government and special debts from local governments to encourage social capital to participate in the reconstruction operation. The transformation of old residential areas needs to solve the problem of "where does the funds come from", and it is necessary to establish a framework system of normalized maintenance and renewal funds.

Social governance must be innovated in the renovation of old residential areas. The transformation of old residential areas is an eternal theme in the process of urban development. Its core concept is to implement the people-centered development idea, the development concept of "innovation, coordination, green, openness and sharing" and the transformation principle of "seeking truth from facts and adapting to local conditions". As a livelihood project, the renovation of old residential areas must encourage the public to actively participate, listen to the opinions of all sectors of society in time, and form a good working atmosphere. Efforts should be made to solve the outstanding problems strongly reflected by the masses, so that the masses can have more sense of gain in the transformation of old residential areas. This process is bound to be a social governance process of mutual consultation, co-construction, co-governance and sharing.
