At the age of 40, it’s time to prevent osteoporosis.

  After the solar term in beginning of winter, the temperature plummeted. According to the annual clinical consultation, the risk of falls and fractures of the elderly will show an upward trend. This is related to environmental factors such as reduced activity in winter, thick clothes and slippery roads, and also related to physical factors such as aging and degeneration of various organs of the elderly. Today we will focus on the problem of osteoporosis. According to the epidemiological survey of osteoporosis in 2018, 6% of male patients with osteoporosis over 50 years old, 32.1% of female patients, and 51.6% of female patients over 65 years old in China. Our country not only has a high proportion of osteoporosis population, but also does not pay enough attention to osteoporosis. The bone mineral density of people over 50 years old is only 3.7%. In fact, both men and women have entered the early stage of bone loss since the age of 40, and we should prevent osteoporosis from this time.

  1 minute self-examination of osteoporosis risk

  By answering the 1-minute osteoporosis risk test of the International Osteoporosis Foundation, you can quickly know whether you have the risk of osteoporosis.

  1. Parents have been diagnosed with osteoporosis or have been fractured after a light fall.

  2. One of the parents has a hunchback.

  3. The actual age is over 40 years old.

  4. Is there a fracture due to a light fall in adulthood?

  5. Do you often fall down (more than once last year) or worry about falling down because you are weak?

  Has the height decreased by more than 3 cm after 6.40 years old?

  7. Is it underweight (body mass index value is less than 19)

  8. Have you ever taken steroid hormones such as cortisone and prednisone for more than 3 months (cortisone is often used to treat asthma, rheumatoid arthritis and some inflammatory diseases)?

  9. Do you have rheumatoid arthritis?

  10. Have you been diagnosed with gastrointestinal diseases or malnutrition such as hyperthyroidism or hyperparathyroidism, type 1 diabetes, Crohn’s disease or celiac disease?

  11. Do you stop menstruating at or before the age of 45?

  12. Have you ever stopped menstruating for more than 12 months except pregnancy, menopause or hysterectomy?

  13. Did you have your ovaries removed before the age of 50 and didn’t take estrogen/progesterone supplements?

  14. Do you often drink a lot (drink more than two units of ethanol every day, which is equivalent to 570ml of beer, 240ml of wine or 60ml of spirits)?

  15. Currently used to smoking or used to smoke.

  16. Exercise less than 30 minutes a day (including doing housework, walking and running, etc.)

  17. Can’t you eat dairy products and don’t take calcium tablets?

  18. Have you been engaged in outdoor activities for less than 10 minutes every day and have not taken vitamin D?

  As long as the answer to one of the above questions is "yes", it is positive, suggesting the risk of osteoporosis, and suggesting bone mineral density testing or evaluating the risk of fracture.

  Bone mineral density detection is suitable for the following groups

  It is not necessary for everyone to do bone mineral density test. Compare the following self-test options to see if you need to have a bone mineral density test.

  1. Women over 65 years old and men over 70 years old, regardless of other risk factors for osteoporosis.

  2. Women under 65 and men under 70 have one or more risk factors for osteoporosis.

  ■ A slight collision or fall will cause a fracture.

  ■ Adults with low sex hormone levels caused by various reasons.

  ■ Those with diseases affecting bone metabolism or a history of using drugs affecting bone metabolism.

  ■ Patients receiving or planning long-term glucocorticoid treatment

  ■ Small and thin people

  ■ Long-term bedridden patients

  ■ People with chronic diarrhea

  ■ The answer to the 1-minute osteoporosis risk test is positive.

  Normal osteoporosis

  Remember "Five Origins and Three Stages" in Prevention and Control

  The prevention and treatment of osteoporosis should follow five principles. First, increase bone mass and increase bone peak value; The second is to delay bone loss; Third, inhibit secondary hyperparathyroidism; The fourth is to prevent the first fracture; Fifth, reasonable dietary structure and nutritional composition ratio, quitting bad eating habits, increasing calcium intake, participating in moderate exercise and increasing sunshine.

  Then, according to these five principles, the measures to prevent osteoporosis can be divided into three stages according to age: primary prevention, secondary prevention and tertiary prevention.

  The primary prevention of osteoporosis is to start from childhood, to reach the highest bone mass (peak bone mass) in one’s life from childhood and adolescence to around 30-35 years old, with the goal of avoiding or alleviating the occurrence of osteoporosis as much as possible. There are mainly the following measures.

  Reasonable dietary structure: milk is the most ideal calcium source, with 120mg of calcium per 100ml of fresh milk and a calcium absorption rate of 30%. The daily intake of calcium can be ensured by taking 500ml for adults, 750ml for children and 800ml for adolescents.

  Choose foods with high calcium content: sesame sauce, shrimp skin, dried seaweed, kelp, milk, bean products and cheese are all foods with high calcium content.

  Vitamin D intake: The daily intake of vitamin D is 400IU, and the vitamin D content in foods such as cod liver oil, canned sardines, egg yolk, shad and chicken liver is high. Sunlight irradiation is also one of the important ways to supplement vitamin D. Walking in soft sunshine for 40 minutes can ensure the vitamin D needed by the body. It is best to choose the irradiation time before 10 a.m. or after 3 p.m., so as to avoid too strong sunlight damaging the skin and eyesight.

  Moderate exercise: participating in moderate exercise is helpful to increase bone mass and increase the peak bone mass.

  Adhere to a healthy lifestyle: not addicted to alcohol and tobacco; Drink less coffee, strong tea and carbonated drinks; Less salt and less sugar.

  When people reach middle age, they reach the secondary prevention stage of osteoporosis. The core of prevention at this stage is to delay the loss of bone mass in middle age and try to avoid the first osteoporotic fracture. Women aged 40-49 and men aged 40-64 enter the prophase of bone loss: the annual bone loss rate of women is 0.4%-0.6% and that of men is 0.3%-0.5%. Women enter the period of rapid bone loss 1-10 years after menopause, and the rate of bone loss is obviously accelerated, while men do not have the period of rapid bone loss. In addition to food supplement, physical exercise and a good lifestyle, the main preventive methods need to be supplemented with vitamin D and appropriate calcium. The recommended intake of vitamin D for adults is 400IU/d, and the maximum tolerable intake is 2000IU/d. When vitamin D is used for prevention and treatment of osteoporosis, the dosage is 800-1200IU/d..

  The tertiary prevention of osteoporosis is the stage of mending after the sheep is dead, mainly aimed at the elderly, which is mainly reflected in inhibiting bone resorption, reducing bone turnover rate and preventing accidental injuries and fractures. Osteoporosis can be treated by supplementing calcium and vitamin D and taking anti-osteoporosis drugs under the guidance of professional doctors, so as to avoid osteoporotic fractures and re-fractures as much as possible.

  Calcium supplementation alone cannot replace treatment.

  The daily calcium intake standard recommended by China Nutrition Association is: 400mg; from birth to 6 months; 600mg; for 6-12 months; 800-1200mg; under 10 years old; 11-24 years old 1200-1500mg;; 1400mg; for pregnant or lactating women over 19 years old; Postmenopausal and postmenopausal women who did not take estrogen 1500mg;; Take estrogen 1000mg; for postmenopausal and postmenopausal women; Middle-aged male 1000mg;; 1000-1500mg for the elderly.

  However, calcium supplementation alone cannot replace the treatment of osteoporosis. Osteoporosis patients can’t overcome the obstacle of calcium utilization by bones only by taking calcium orally, so they should be treated regularly under the guidance of doctors.

  About 30% of elderly people over 60 years old and postmenopausal women have gastric acid deficiency. If they have flatulence and constipation after taking calcium carbonate, they should change to calcium citrate. The absorption of calcium citrate is independent of gastric acid and can prevent kidney calculi, which is especially suitable for those with gastric acid deficiency.

  However, whether calcium supplementation is needed or not should be decided by consulting a specialist in a regular hospital and doing a bone mineral density examination. There is a threshold for calcium absorption. Excessive supplementation is not only a waste, but also can lead to kidney calculi’s disease, ectopic calcification and atherosclerosis. Kidney calculi, patients with advanced bone metastasis, hypercalcemia and cardiac and renal insufficiency are forbidden to supplement calcium.

The United Nations Security Council held its first meeting on artificial intelligence, and China put forward five principles of governance.

  UN Security Council Secretary-General Guterres called for the establishment of a global regulatory body to supervise artificial intelligence, in much the same way as other institutions supervise aviation, climate and nuclear energy. The proposed institution is composed of artificial intelligence experts, sharing their expertise with government and administrative agencies that may lack relevant technical knowledge.

  Zhang Jun, Permanent Representative of China to the United Nations, pointed out that in order to seek technological hegemony and build exclusive circles, some developed countries maliciously obstruct the technological development of other countries with various excuses and actions and artificially create technological barriers, which China resolutely opposes.

  On July 18th, local time, the UN Security Council held a high-level public meeting with the theme of "Opportunities and risks brought by artificial intelligence to international peace and security". Antonio guterres, Secretary-General of the Security Council, called for the establishment of a global regulatory body to supervise this new technology.

  This is the first time that the Security Council has held a meeting on artificial intelligence. Zhang Jun, Permanent Representative of China to the United Nations, put forward five principles on the governance of artificial intelligence: first, adhere to ethics first; second, adhere to safety and controllability; third, adhere to fairness and inclusiveness; fourth, adhere to openness and tolerance; and fifth, adhere to peaceful use.

  It is still far from reaching a legally binding resolution.

  On the same day, Guterres, Jack Clark, co-founder of Anthropic, an artificial intelligence startup, and Ceng Yi, a researcher at the Institute of Automation, China Academy of Sciences, gave a briefing.

  Guterres warned that artificial intelligence is playing a role in many fields, but it may also be used by malicious people, including using it for terrorism, inciting hatred and violence. He welcomed the call for the establishment of a new UN agency, saying it would help to maximize the role of artificial intelligence and better manage risks. He said that the artificial intelligence regulatory agency of the United Nations should standardize, supervise and enforce the rules of artificial intelligence, and the supervision method is roughly the same as that of other institutions in supervising aviation, climate and nuclear energy.

  At the meeting, diplomats and leading experts in the field of artificial intelligence explained to the Security Council the risks and threats of artificial intelligence technology, as well as its scientific and social benefits. They said that although the development speed of this technology is accelerating, there are still many unknowns. "It’s like making an engine without understanding the combustion principle." Clark said that private companies should not be the only creators and regulators of artificial intelligence.

  The body proposed by the Security Council is composed of experts in the field of artificial intelligence, who will share their expertise with government and administrative agencies that may lack technical knowledge to solve the threat of artificial intelligence.

  At present, it is still far from reaching a legally binding resolution on governance. However, most diplomats support the formulation of global governance mechanisms and international rules.

  James Cleverly, the British Foreign Secretary who presided over the meeting, said: "No country is immune from artificial intelligence, so we must involve the broadest alliance of international actors from all fields." Britain holds the rotating presidency of the Security Council this month.

  China: Oppose the use of artificial intelligence to seek military hegemony.

  Zhang Jun pointed out in his speech that artificial intelligence, as a "double-edged sword", is good or bad, good or evil, depending on how human beings use it, how to regulate it, and how to coordinate science, development and security. The international community should uphold the true spirit of multilateralism, conduct extensive dialogues, constantly build consensus, and explore the guiding principles for the governance of artificial intelligence. China supports the United Nations to play a central coordinating role in this regard, supports Secretary-General Guterres to convene in-depth discussions among all parties, and supports all countries, especially developing countries, to fully participate in and make contributions.

  Zhang Jun put forward five principles about artificial intelligence governance. First, adhere to ethics first. To ensure that artificial intelligence technology will always benefit mankind, we must take "people-oriented" and "intelligence for goodness" as the basic criteria to standardize the development direction of artificial intelligence and avoid this technology becoming a "runaway wild horse". On this basis, gradually establish and improve the artificial intelligence ethics, laws and regulations and policy system.

  The second is to adhere to safety and controllability. There are many uncertainties in the development and application of artificial intelligence related technologies, and safety is the bottom line that must be kept. The international community should strengthen risk awareness, establish an effective risk early warning and response mechanism, ensure that risks beyond human control do not occur, ensure that machines do not kill themselves, and ensure that humans have the ability to press the stop button at critical moments.

  Guterres said on the same day that the United Nations must reach a legally binding agreement before 2026 to ban the use of artificial intelligence in automated war weapons.

  The third is to adhere to fairness and inclusiveness. Zhang Jun said that developing countries’ equal access to and utilization of artificial intelligence technologies, products and services is essential to bridge the technological gap, digital gap and development gap between North and South. In order to seek hegemony in science and technology and build an exclusive circle, some developed countries maliciously obstruct the technological development of other countries with various excuses and actions and artificially create barriers to science and technology. China firmly opposes this.

  The fourth is to adhere to openness and tolerance. The development of science and technology should achieve a relative balance between promoting technological progress and ensuring safe application. The best way is to maintain open cooperation, encourage interdisciplinary, cross-disciplinary, cross-regional and cross-border exchanges and dialogues, oppose various forms of "small courtyard walls" and "decoupling and breaking chains", and create an open, inclusive, fair and non-discriminatory environment for scientific and technological development.

  The fifth is to adhere to peaceful use. It is necessary to focus on tapping the potential of artificial intelligence in promoting sustainable development, promoting cross-disciplinary integration and innovation, and better empowering global development. The Security Council can deeply study the application and influence of artificial intelligence in conflict situations and take measures to enrich the United Nations peace toolbox. All countries should uphold a responsible national defense policy and oppose the use of artificial intelligence to seek military hegemony and undermine the sovereignty and territorial integrity of other countries.

  Zhang Jun said that China adheres to the concept of the community of human destiny and has always participated in the global cooperation and governance of artificial intelligence with a highly responsible attitude, and has successively submitted two position papers on the military application and ethical governance of artificial intelligence on the UN platform. China is willing to work with the international community to actively implement global development initiatives, global security initiatives and global civilization initiatives in the field of artificial intelligence, adhere to development priorities, safeguard common security, promote cross-cultural exchanges and cooperation, join hands with countries to share artificial intelligence technological achievements, and jointly prevent and respond to risk challenges.

I’ve been invisible for several years, and the folding screen is ok again.

Text | Deep Eyes Finance Zhang Wei

The folding screen caught fire in 2022 and the fire spread all the way to 2023.

The title of "the first year of folding screen" was born in 2022, one of the reasons is the high growth of folding screen shipments in 2022. According to IDC data, in the third quarter, China shipped more than 1 million folding screens, up about 246% year-on-year.

More importantly, this transcript of the folding screen was achieved in an environment of overall decline in smartphone shipments. According to the consulting data of Ai Media, the overall shipment volume of China mobile phone market will drop from 560 million in 2016 to 310 million in 2020. In 2021, mobile phone shipments rebounded slightly, but the overall environment is still not optimistic, with an annual shipment of only 350 million units.

It is not only the China market that participates in this folding screen carnival. According to Counterpoint research report, it is estimated that the global folding screen mobile phone market will increase by 52% year-on-year in 2023, reaching 22.7 million units.

You know, since the birth of the folding screen mobile phone, it has always been a niche track because of its relatively small market share, average sales volume and general market response.

When it was launched in the early years, it was also vomited by users because of the high price, obvious screen creases and heavy weight. Then, why did the folding screen, which was not welcomed by capital and market before, grow against the trend this year?

1. Capital betting, folding screen to become a new story?

Behind the fierceness of folding screen mobile phones is the embarrassment that mobile phone manufacturers urgently need to grow.

In the downturn of consumer market, the butterfly effect of mobile phone consumers is triggered: consumers who have no money in their belts naturally reduce their demand for mobile phones, and their replacement rate drops, which leads to a downward trend in mobile phone shipments. From January to November 2022, the total shipments of mobile phones in the domestic market totaled 244 million units, down 20.2% year-on-year.

In this context, as a relatively new product form, folding screen has become a "life-saving straw" in the mobile phone industry, and major mobile phone manufacturers have taken this opportunity to get involved in folding screen mobile phones.

At present, almost all mainstream mobile phone manufacturers have released new folding screen mobile phones, including Huawei’s Pocket S, Samsung’s Galaxy Z Flip4, OPPO’s Find N, Xiaomi’s Mix Fold2, VIVO’s X Fold+, etc., and the competition is fierce.

In 2022, Samsung, Huawei, OPPO, VIVO, Xiaomi and other mobile phone manufacturers released more than 10 folding screen mobile phones. According to the current news, there will be many new folding screen machines released in 2023, and even Apple has rumors that it will release folding screen smart phones in 2023.

In the past, high-end machines competed for chips, image capabilities, screen refresh rates, etc. Now, due to the involvement of smartphones in the Red Sea, technologies have entered a mature stage, and these technologies have been decentralized to low-end machines.

Although mobile phone manufacturers bet on the folding screen market, the herd effect is not fully applicable to consumers. In the era of information explosion, consumers are no longer the lambs to be slaughtered who are completely obedient to others.

On the one hand, from the perspective of mobile phone form, the design of folding screen is more futuristic. Compared with the previous folding screen mobile phones, the subdivision of scenes is one of the factors contributing to the growth of folding screen mobile phones, which means that folding screen mobile phones can radiate a wider range of people, and their product design, size, thickness and operation are different from business scenes, car scenes and game fields.

For example, OPPO Find N2 has not only paid attention to the internal and external screens, but also started to cut into the half-folded hovering, so that the mobile phone has a natural bracket, which brings more brand-new experiences to users from entertainment, and is more abundant in watching videos, photography and other leisure games.

Another example is Huawei’s main "folding screen meta-universe", which starts from smart life and exerts its strength on the external screen, and can obtain the weather, payment, camera, application and other dynamics without unfolding the screen. It can be said that the segmentation scene of the folding screen has jointly contributed to the shipment.

At the same time, the product forms of horizontal folding inner screen, horizontal folding outer screen and vertical folding screen also meet the habits and preferences of different people.

On the other hand, high-end is the only way for most industries to mature, and the mobile phone industry is no exception. According to relevant data, the average selling price of mobile phones in China market has increased from 1500-2000 yuan to 3000 yuan. The sales volume is falling, the average selling price is rising, and high-end mobile phones are increasingly favored by consumers.

In order to enhance the competitiveness of products, mobile phone companies are gradually abandoning the original sea tactics and moving towards the "fine machine" mode. According to the data released by China Xintong Institute, from January to October 2022, there were 308 new models on domestic brands, down 10% year-on-year.

The folding screen just meets the needs of users’ high-end machines. However, compared with the "puffy" folding screen four years ago, the folding screen now is more "material".

Previous folding screens always revolved around two problems: poor quality and high price. The report on the development trend of GFK China Folding Screen Smartphone released in 2022 shows that weight and price are still the core issues that prevent users from buying folding phones.

At the same time, according to the survey data of Ai Media Consulting, nearly 80% of the interviewed users buy folding screen mobile phones for entertainment needs, and the reason why the interviewed users don’t buy folding screen mobile phones is that they are expensive, accounting for 59.5%.

Under the focus of mobile phone manufacturers, according to the folding screen mobile phones recently launched by mobile phone manufacturers, today’s folding screen mobile phones are lighter, cheaper and have stronger endurance. For example, on December 25th, OPPO released the new folding screen flagship machine-—OPPO Find N2, which weighs only 233g and costs less than 9000 yuan.

Like the flagship machine Pocket S launched by Huawei, the weight is controlled at 190 grams while maintaining the screen size; Samsung Galaxy Z Fold4 is only 263 grams; Xiaomi’s MIX Fold weighs only 262 grams. Nowadays, almost all folding screens have controlled the weight below 300 grams, which makes it more convenient for users to use.

The price problem doesn’t stop there, and the price will remain downward. According to the Counterpoint research report, in view of the increasingly fierce competition in the folding screen smartphone market, it is expected that its price will be more close to the people in 2023. It can be said that the folding screen mobile phone confirms its "worth" step by step.

2. Self-developed core parts, "cost reduction" achieved initial results.

In order to change the status quo and make the folding screen realize another spring in the mobile phone industry, mobile phone manufacturers choose to break through from the upstream of the industrial chain.

Previously, in the folding screen mobile phone industry, Samsung not only dominated the industry, but also controlled the main components. According to Fomalhaut Techno Solution in the report, Huawei folding mobile phones Mate Xs and Xiaomi Mix Fold both use flexible screens made by Samsung, and Korean parts account for about 30% ~ 50% of the total.

According to the Monitoring Report of Folding Screen Mobile Phone Industry in China in 2022, the quality problem is the biggest concern for users to buy folding screens. Among the quality problems concerned by consumers, the crease of mobile phone is the most concerned, and hinge technology is the key to the crease problem.

And the main cost of folding screen mobile phone is 69% higher than that of non-folding mobile phone, of which the main cost comes from hinge and screen. According to the data of CGS—CIMB, the BOM cost of Galaxy Fold, Samsung’s first-generation folding screen mobile phone, was 636.7 USD, of which the display module cost was 218.8 USD, accounting for 34.4%, and the mechanical/electromechanical structure cost was 87.5 USD, accounting for 13.7%.

The display module cost of Samsung’s bar phone Galaxy S9+ accounts for 21%, and the mechanical/electromechanical structure cost accounts for 7.9%. From the perspective of BOM cost, screens and hinges are the main sources of the increase in the cost of folding screens.

In order to eliminate "bad reviews" and prevent key parts such as hinges and flexible screens from getting stuck in the neck, China brand has been gradually realized.Domestic substitution. The data shows that the number of patent applications related to folding screen hinge technology in China is on the rise, and the number of patent applications related to folding screen hinge in China is 160 in 2020.

At present, independent research and development of hinge technology has gradually become the core solution of mainstream terminal factories. According to the incomplete statistics of the potential silver optical chain, the hinge technology of various terminal factories has been constantly breaking through and innovating with the release of products, such as the aerospace-grade floating silver hinge of VIVO and the double-rotating eagle wing hinge of Huawei.

On the other hand, the folding screen mobile phone on the market has been optimized from 100,000 times in the early stage to 400,000 times, which is obviously improved.

According to the forecast of relevant industry organizations, the global hinge market for folding screen mobile phones will be 1.267 billion yuan in 2021, and it is expected to increase by 136.8% year-on-year to 2.999 billion yuan in 2022, which shows that hinge technology is the focus of the current breakthrough of folding screen.

Moreover, the domestic upstream display industry has achieved breakthroughs in technology, manufacturing and market, and domestic panel manufacturers such as BOE, Shentianma, TCL Huaxing and Visionox have accelerated the innovation and mass production of flexible screens. According to Omdia data, the global OLED production capacity is expected to increase from 31.51 million square meters in 2021 to 75 million square meters in 2027.

Including the optimization of appearance, Samsung has weakened the width of the hinge and the black edge of the screen, accounting for the external screen of the Galaxy Z Fold.

Judging from the recently released new products, the functions of folding screen mobile phones have become more and more perfect, such as the newly released X Fold+ of VIVO, which continues the characteristics of VIVO bar mobile phones, focusing on battery life and fast charging functions. Similarly, the latest Find N2 released by OPPO also has the function of improving endurance and satisfying fast charging.

3. Has the problem of folding screen been solved?

The folding screen mobile phone market has maintained growth for several consecutive quarters, and the growth rate in the third quarter of this year has also reached a new high. In the forecasts of various institutions, the folding screen market is expected to grow significantly.

So, can this situation be maintained, and who is buying a folding screen mobile phone?

The market is inseparable from the word supply and demand. If there is supply, there will be demand.

From the demand side, users as a whole are younger. The data shows that the young people under the age of 35 among the latest folding screen mobile phone users have increased significantly, accounting for 58.2%. Therefore, the supply and demand sides change rapidly in functions such as battery life and thinness.

In addition, according to the daily interactive big data, users of folding screen mobile phones not only have high requirements for mobile phones, but also have certain pursuits for quality of life. For example, they love to use life sharing apps such as Little Red Book and Public Comment.

From the demand side, the folding screen mobile phone has gradually developed from the ready to the development stage. The oversized screen is no longer as "chicken ribs" as before, but has derived more entertainment, business and other performances in terms of user needs.

However, after a year of focus, have the problems of folding screen phones really been solved?

Of course not. In the process of development, any industry will inevitably encounter different problems.

Even though the folding screen market has maintained growth for several consecutive quarters, the reason for maintaining high growth lies more in the focus of mobile phone manufacturers and the small market scale.

On the whole, the optimization of folding screen market has achieved initial results, but the problem has not really been solved. Different from the big step forward of the industrial chain, the recognition degree of folding screen is still at a low level, whether from product design to personal experience.

Judging from the black cat complaint data, most complaints about folding screen mobile phones are still focused on screen quality.

At present, most social platforms are still full of spit on folding screen mobile phones, and some of the reasons for spit are still the problems that were spit out a few years ago, including but not limited to screen off-line, liquid leakage, black spots and so on.

The main frequency of the folding screen model is not as durable as that of the integrated model, and the damage degree is higher. What is more "fatal" is that the follow-up maintenance cost is also higher. Taking Samsung’s latest Z Flod4 as an example, the price of the inner screen+outer screen assembly has reached 4,460 yuan, even for the lower-priced Samsung ZFILIP 4, the assembly price of the inner and outer screens also needs 2,460 yuan.

In the solution to the screen, the practice of major mobile phone manufacturers is to launch a broken screen saver service. Like Huawei’s Pocket S and VIVO’s Fold+, the official broken screensaver price is as high as 1199. The broken screensaver is not only high in price, but also guaranteed for only one year, which invisibly increases the follow-up cost of consumers.

The development of folding screen is also in line with the "first cause effect". In the early stage of development, due to the product’s too small, high price, fragile screen and other problems, it brought a deep negative impression to consumers, which led to the difficulty of market education in the later stage and the low recognition of the product.

One of the key problems is that the crease of mobile phone has not been verified by the market.

Even with the rapid development of hinge technology, the current folding screen market is still in the development stage. The major mobile phone manufacturers have launched newly upgraded folding screen mobile phones for more than one year, while the average service life of a mobile phone is three years.

The screen material will accelerate the aging speed after being folded for a long time. Although official website publicizes that the current flexible screen can be folded for 500,000 times, it does not rule out the possibility that the screen will be folded because of repeated folding.

According to the observation of "Deep Eyes Finance", the folding screen mobile phone just changes the product form, its functional integrity is not as good as that of the straight smart phone, and the improved functions are basically corresponding to the straight smart phone.

The main highlights of folding screen are split screen and multi-video viewing, but these requirements are not just needed by users and are irreplaceable.

As a high-end series product that has been tempered in the market for four years, its underlying logic is undoubtedly to meet the premise that "the folding screen is indeed better than the ordinary straight mobile phone".

Compared with the straight mobile phone, the straight mobile phone with the same price is obviously better from the processor. For example, Huawei’s Pocket S is equipped with 4G Snapdragon 778 processor, and the price starts at 5988. The P50 released by Huawei last year was equipped with Snapdragon 888 processor, and the price was only 4,088 when it was released.

Hard power is important, and soft power is indispensable. On the whole, the folding screen mobile phone still has a large market space, but when imagining the future, we should also study how to meet the demand side and strive for a larger market share.

The way of reading in the eyes of academicians

  "Looking at today’s society, the fragmentation trend of reading is relatively strong. This way of learning is short and fast, and knowledge is acquired quickly and lost quickly. If you want to read some classic works, it takes a lot of time and energy, but the results are also great. " Recently, Liu Jiaqi, an octogenarian academician of the China Academy of Sciences and a volcanic geologist and Quaternary geologist, shared his "way of reading" with the public at the National Library’s "Mr.’ s Study" activity.

  "Reading can not only increase knowledge and talents, broaden horizons, but also cultivate sentiment and gain spiritual enjoyment." Liu jiaqi said that when he was a child, reading was a luxury. Reading is difficult, borrowing books is difficult. At that time, he also thought that he could be a librarian in the future, and reading might be more convenient.

  In Liu Jiaqi’s view, reading is the way to grow up. His fate is also changed by reading. "My road to study, as Qu Yuan’s poem says, ‘ It’s a long way to go in Xiu Yuan, and I will go up and down for it ’ 。”

  Under difficult conditions, Liu Jiaqi went all the way from primary school to university, and later went to graduate school, but still felt that what he had learned was limited. In 1978, 10 years after graduation, Liu Jiaqi took the postgraduate exam again and came to Beijing. "I turned 40 when I was 30, and I wanted to drive back the past 10 years."

  After careful calculation, Liu Jiaqi spent 27 years and 8 months as a student. "Reading is very important for the growth of my life." Liu Jiaxuan said. About how to read? He summed up some experiences.

  First of all, we should be clear about the purpose of reading. To be wise and skilled, be determined to be a man first, and be determined to be a man first; Don’t fish for three days and dry the net for two days when reading.

  In the process of reading, we should pay attention to methods and think. "It is better if you can find faults in books." Liu Jiaqi said that reading should be selective, and it is necessary to read good books and classics; It is necessary to combine professional books with non-professional books, scientific books with artistic books, and systematic books with fragmented information. Don’t always indulge in fragmented information.

  "Reading is not only about growing up, but more importantly, making contributions to the country in the future." Liu Jiaqi studied earth science, and he told young people that in the process of studying, they should also specialize in one line and love another.

The small plane was chased by the US military plane and eventually crashed. The information on the crew was revealed!

  BEIJING, June 5 (Xinhua)-According to foreign media reports, on the 4th local time, a light plane was suspected to have broken into the sky above Washington, USA, and was chased by American fighter planes at high speed. The light plane eventually crashed in Virginia, and the identity of the owner and crew of the plane attracted attention.

  According to The Washington Post and The New York Times, this plane is a private business plane registered with a company named Encore Motors of Melbourne in Florida, USA.

  American media contacted the company’s operator, 75-year-old John Roupell, by telephone. He revealed that his daughter, two-year-old granddaughter, nanny and pilot were all on the plane.

  John Roupell said he knew little about the crash. He said in a choked voice that if the plane loses pressure, "they will all fall asleep and never wake up again … … I don’t think they have found the wreckage yet. It drops at a speed of 20,000 feet per minute, and no one can survive in this situation. "

  The Daily Beast, an American news website, noted that Barbara Roupell, the wife of John Roupell, was registered as the president of Encore Motors of Melbourne, but she declined to comment.

  According to the records of the Federal Election Commission obtained by this website, Mr. and Mrs. John Roupell are both well-known business people in Florida. In the past few years, they have donated money to many Republican candidates running for federal office, including hundreds of thousands of dollars to former President Trump and his political organization.

  According to the report, public information shows that Barbara Roupell is also a long-term member of the National Rifle Association (NRA). Since 2002, she has been a member of the NRA Women’s Leadership Committee.

  On the 4th local time, a Cessna light plane was suspected to have broken into the sky above Washington, and the US F-16 jet fighter scrambled for high-speed pursuit, causing a sonic boom over the US capital. During this period, the US military tried to establish contact with the pilots on Cessna plane.

  According to the statement of the Federal Aviation Administration (FAA), the Cessna plane took off from Elizabethan, Tennessee on the 4th and was scheduled to fly to Long Island, new york. But inexplicably, the plane turned around over Long Island and plummeted over Washington, D.C.. The plane later crashed in the mountains of southwest Virginia.

  It is not clear why the Cessna plane did not respond to the control of the authorities, and it is not clear why it crashed.

Two Apple 16 yuan netizens shouted: I can’t afford fruit this year.

  Recently, many people have found that the price of fruits has gone up. Fruits such as litchi and cherries, which are usually relatively expensive, are even more expensive than "don’t want to buy" … … According to the data released by the Nutrition Society of China recently, the average daily fruit intake of urban and rural residents in China is at a low level, so experts suggest that a person should eat one catty of vegetables and half a catty of fruit every day. In this regard, the online discussion group went astray, "Fruit is more expensive than meat", which expressed the voice of many netizens in one sentence.

  Fruit is more expensive than meat.

  Netizen: "My heart hurts when I eat."

  Yang Yuexin, chairman of the China Nutrition Society, pointed out that fruits and vegetables provide the human body with daily essential vitamins, minerals, dietary fiber, plant compounds and other nutrients, and are an important part of a reasonable diet. Insufficient intake of fruits and vegetables will increase the morbidity and mortality of hypertension, cardiovascular disease and cancer. Ma Guansheng, vice chairman of the Nutrition Society of China, even suggested that we should ensure that there are vegetables in meals and fruits every day, and one should eat one catty of vegetables and half a catty of fruits every day. Unexpectedly, for this statement, many netizens have exploded, and the topic has gone astray collectively. Listen to the personal experience of netizens:

  "peaches are 20 yuan a catty, and you can’t afford fruit in Hainan"; "Nectarine is 15 yuan a catty, and the taste is still average"; "Six little mango 58 yuan, really can’t afford it"; "A quarter of a watermelon is 17 yuan, which hurts when you eat it"; "Even the unpretentious apples have gone up in price. The total price of two apples with average appearance and taste is 15.98 yuan, almost 8 yuan each. Can you believe it?" Judging from everyone’s feedback, the most "kind" banana is: "Just three bananas are more than a catty, and all the others have started with six pieces. I really can’t afford it."

  Netizens like rabbits sleeping standing up: I can’t afford to eat, and now fruit is more expensive than meat. The glory of the king, a netizen, beat his younger brother: Now the price of fruit is almost catching up with that of seafood. I can’t afford it, so I can only eat one and a half kilos of vegetables.

  The reporter visited the retail terminal

  Three apples are equal to a catty of pork belly.

  On the 14th, the reporter visited several farmers’ markets and supermarkets in Chengdu. The price tag on the fruit and what the vendors said confirmed this: the price of fruit is indeed a bit high recently.

  In a chain supermarket, a catty of cherries is 50 yuan, and a randomly weighed cherry is 1.25 yuan, which can buy an egg with a moderate price; A catty of red Fuji 9.9 yuan, the price of three red Fuji apples can buy a catty of pork belly; Peaches are 16.8 yuan a catty, and the prices of three peaches and a catty of pork belly are also quite the same. "The most expensive is cherries, 50 yuan/kg, cherry 35 yuan/kg, mangosteen 25 yuan/kg, and the cheapest banana is 5 yuan/kg." In an ordinary farmer’s market in Jinjiang District, a fruit merchant told reporters that even the most common apples have sold to 11 yuan for 1 catty, which is several pieces higher than the price at this time last year. In the store next door, the price of cherries has reached 70 yuan/Jin. Vendors say that all the fruits sold in the store are seasonal, and if they are sold out of season, the price is more expensive. "Since the beginning of this year, the price of fruit has risen sharply, and our business is not good." In the farmer’s market, the vendors frowned. As for the reasons, they are not very clear.

  On a nationwide scale, the prices of various fruits are on the rise. According to the monitoring of "National Agricultural Products Wholesale Market Price Information System" of the Ministry of Agriculture and Rural Affairs, among fruits, the biggest increase is Red Fuji apple. Since mid-March, the ring has been showing a year-on-year growth trend, and in the past two weeks, the year-on-year increase has even exceeded 40%. In addition, after the Spring Festival, the price of bananas has been higher than that of the same period last year, and the price of watermelons has been rising year-on-year for nearly two months.

  The fruit retail data released recently in many places also point to the same result: price increase. For example, according to the information released by the Guangdong Provincial Department of Commerce, the average retail price of fruits increased by 0.2% from May 6 to May 12. Due to the rainy weather last week, the transportation and storage costs of fruits increased slightly, driving the overall price of fruits to rise. According to the data of Guangxi Department of Commerce, from May 6 to May 12, the retail price of fruits was 9.46 yuan/kg, and the price increased by 1.94% from the previous month. Among the seven retail fruit varieties monitored, the retail prices of apples, grapes, pears, watermelons and lychees rose.

  Why is fruit so expensive this year?

  Too much rain during the flowering period of Longquan loquat leads to reduced production.

  "The price of loquat is good this year, and the bad ones are removed, and the large and small fruits are packaged and sold. 10 yuan weighs a catty, which is twice as high as last year." Zeng Xinjian is a big loquat planter in Longquan industrial and rural areas, planting 20 mu of loquat. Due to the weather, there is too much rain at the flowering stage of loquat, which leads to insufficient flower bud differentiation, low fruiting rate and nearly half of loquat yield. "In the past, it was possible to produce 1,500 kg to 2,000 kg per mu, but now it is reduced by about 1,000 kg per mu, and the overall output is reduced by at least 40%." Zeng Xinjian said that at the end of April, loquat was about to mature, entered the last expansion period, and suffered from high temperature. The loquat facing the sun all showed "sun scars" to varying degrees. "The taste of this kind of loquat has not changed, but the appearance is very poor, and the purchaser will not want it. It must be picked out when picking." Zeng Xinjian said that as a result, the output has dropped by tens of thousands of Jin, making the overall output drop by 60%, the output drop and the price of loquat rise, making his income this year lower than last year. "Last year, it was able to sell for 120,000 yuan, and this year it is estimated to be only 80,000 yuan."

  Zhang Wenxiang, director of the workers’ and peasants’ villages, said that there are 2,000 mu of loquat planting areas in industrial and rural areas. At present, the purchase price is from 10 yuan to 12 yuan/kg. Due to weather factors, the overall output has dropped this year, but the price has doubled compared with the same period last year. "It is estimated that the income of villagers this year will be the same as last year."

  Large watermelon growers switched jobs, resulting in reduced production.

  At 4 o’clock in the afternoon, Chengdu Pengzhou Mengyang Fruit Wholesale Market was deserted. Last year, the watermelon area where Ren Dajie was located was not like this.

  "Even at this time last year, the watermelons were sold from one end to the other." Sister Ren has been engaged in watermelon business for more than ten years. This year, the price of watermelon is really high and "affordable". At present, Chengdu basically sells local watermelons in Dayi. It has been sold for half a month since 3.1 yuan/Jin -3.3 yuan/Jin, which was listed in early May, and the wholesale price is still maintained at 2.5 yuan/Jin -2.6 yuan/Jin.

  "In previous years, just two or three pieces were listed. In a few days, a large number of watermelons were listed, and they immediately fell to a few hairs." Ren Dajie said that the main reason is the reduction of production. In the past few years, the price of watermelon continued to be low. Last year, it suffered from floods. Large growers lost money year after year, and large growers in other places retreated and changed careers, resulting in a decline in production, at least by half. "As soon as the price is high, many people will stop eating, and fewer people will buy melons."

  Apple and pear suffered from frost during flowering period, resulting in reduced production.

  Speaking of the prices of apples and pears, Deng Darong, who has been a fruit wholesaler for 30 years, said, "It is rare for decades, and the price has risen fiercely, quickly and greatly." Deng Darong said that the apples sold in the market are all from Jingning County, Gansu Province. At present, the wholesale price of apples varies according to the size of the fruit, and the price is 5 yuan/Jin -8 yuan Jin. The reason is that in April last year, when the apple bloomed, the northern part suffered from frost, the fruit setting rate was low, and the output was significantly reduced by 2/3, and the appearance was not good. Since it was purchased and put into storage last year, all localities began to snap up, and the purchase price per Jin was higher than that of previous years. This year,

  "When the output is small, all localities are grabbing goods, and the price is even higher when they grab it." Deng Darong said that in addition to apples, there are pears and other fruits affected by frost. He predicted that although apples and pears are out of stock at present, there is little room for future price increases. "It has reached the peak, and the possibility of rising again is very small."

  Insufficient nutrition of litchi and other reasons lead to reduced production.

  For litchi, this year is a veritable small year. At present, the litchi sold in Chengdu comes from Haikou, and the output has decreased by at least two-thirds. Now the wholesale price is 17 yuan/Jin -18 yuan/Jin. He Qun, the person in charge of Renping Fruit Industry Co., Ltd., said that litchi has a three-year cycle. The year before last and last year were bumper harvest years, and this year happens to be a small year for litchi. "The bumper harvest for two consecutive years has excessively consumed the nutrition of branches. In addition, last year, it was a warm winter in the south, and it was affected by rain, which directly led to a decrease in yield." She predicted that Guangdong litchi would be listed in the next few days, but it was also affected by the reduction in production, and the price dropped slightly, but there was not much room for decline.

  The origin of cherries is not large, and the price has been high over the years.

  And online celebrity fruit "cherries", He Qun said, this is a normal price, which is not much different from previous years. Recently, cherries sold for 70 to 80 yuan a catty, because cherries are produced in Shandong. "People produce early, the output is not big, and the price has been high over the years." He Qun said. Now Wenchuan and Hanyuan cherries have been listed, and the wholesale price is from 15 yuan/kg to 25 yuan/kg, and the price is not much different from previous years.

  National Bureau of Statistics: Prices will not remain high.

  The State Council Press Office held a press conference on the morning of 15th. Liu Aihua, spokesperson of the National Bureau of Statistics, introduced the national economic operation in April this year and answered relevant questions. Liu Aihua said that consumer prices rose by 2.5% in April, an increase of 0.2 percentage points over the previous month. The year-on-year increase of individual varieties has risen, and the year-on-year increase of pork, fresh vegetables and fresh fruits has exceeded 10%. There are two factors that led to the increase in April, one is the increase in pork prices, and the other is that fresh vegetables and fruits with strong seasonality are greatly affected by seasonality. Among them, from the price of fresh vegetables and fresh fruits, these two varieties are obviously affected by seasonal factors of extreme weather, and these seasonal short-term shocks are not sustainable, and the price increase of fresh vegetables and fresh fruits will not last at a high level. From these aspects, food prices have a stable foundation.

With the arrival of spring, "Document No.1" emphasizes these five "strengths"

  Spring is the first year of the year, and agriculture is the first. At the beginning of the Spring Festival, "Document No.1" arrived as scheduled with spring. This is the first Central Document No.1 issued after the 20th Party Congress, which writes a blueprint for rural revitalization and emphasizes "keep ‘ Agriculture, countryside and farmers ’ The basic dish is very important and can’t be lost, which conveys a strong signal of emphasizing agriculture and strengthening agriculture.

  Document No.1 of the Central Committee has made nine arrangements for comprehensively promoting the key work of rural revitalization. The first task is to pay close attention to the stable production and supply of grain and important agricultural products. It is the experience of last year and the direction of this year that "agriculture, rural areas and farmers" are improving and taking the initiative in the overall situation. Looking back on 2022, in the face of the stormy international environment and arduous domestic reform, development and stability tasks, China’s grain production achieved "19 consecutive harvests" and "agriculture, rural areas and farmers" made solid progress, winning the initiative to effectively cope with the impact of unexpected factors. Looking forward to 2023, to turn the big goal of "keeping the national grain output above 1.3 trillion Jin" into a small goal, we must not only stabilize the area, focus on yield per unit area, and strive to increase production, but also strive to ensure that farmers can earn money from growing grain. Only by increasing production and stopping losses, and simultaneously strengthening agricultural infrastructure construction, agricultural science and technology and equipment support can we protect the rice bag, vegetable basket and oil bottle.

  A strong country must first strengthen agriculture, and a strong agriculture can strengthen the country. Earlier, the Party’s Report to the 20th CPC National Congress first proposed "accelerating the construction of an agricultural power". What is the strength of an agricultural power? Document No.1 of the Central Committee gives the answer — — Strong supply guarantee, strong scientific and technological equipment, strong management system, strong industrial toughness and strong competitiveness. To achieve these five goals, the bottom line is to ensure food security and prevent large-scale poverty. On this basis, we must solidly promote key tasks such as rural development, rural construction and rural governance. It is a strategic and long-term task to strengthen agriculture and strengthen agriculture. At present, only by focusing on promoting rural revitalization in an all-round way, concentrating on human input, material allocation and financial security, and solidly promoting the "five revitalization" of rural industries, talents, culture, ecology and organization can we provide solid support for accelerating the construction of an agricultural power.

  In the final analysis, promoting the high-quality development of agriculture and rural revitalization is to benefit farmers and meet their expectations for a better life. This needs to promote the overall improvement of the countryside from the outside to the inside, both in form and spirit, so that farmers can be rich in both pockets and brains. Rich "pocket" depends on promoting employment, increasing skills and carrying out reforms. Broaden the channels of increasing income and getting rich, so that hundreds of millions of peasants can get property benefits in a down-to-earth manner and share the fruits of reform, which can better stimulate their enthusiasm. Rich "brains" require equal attention to rural shaping and soul casting, and coordination between material civilization and spiritual civilization, so that the "high-priced bride price" and "big-scale operation" that everyone cares about can be effectively managed, and the customs can be truly changed, so that the countryside can be stable and peaceful, livable and suitable for business, and the happiness index can be higher and higher.

  A year’s plan starts with spring. At present, from Woye in the South to the granary in the Central Plains, all localities are in full swing to carry out spring tube spring ploughing, and the vast countryside is full of spring and hope. If the nation is to be revived, the countryside will be revitalized. In the new year, we should make strenuous efforts, implement the No.1 Document of the Central Committee, and keep the basics of "agriculture, countryside and farmers", which will surely enable the broad masses of peasants to live a good life with a growing sense of gain, and make progress in building a strong agricultural country and promoting rural revitalization.

On the first day of work years later, all walks of life in the new district quickly entered the working state.

  Open column language

  New year’s new atmosphere, strive to open a new bureau! 2023 is the first year to implement the spirit of the 20th Party Congress, a crucial year for Tianjin to build a socialist modern metropolis in an all-round way, and a crucial year to speed up the construction of a beautiful "coastal city" in the new era. At the beginning of the new year in the Year of the Rabbit, all the development zones, towns, departments and units in Binhai New Area are working hard, and every minute counts. A tough battle centered on the implementation of high-quality development support and leading actions in Binhai New Area is blowing horns and beating drums in the land of Bincheng. The vast number of builders in the new area are facing difficulties and seizing the opportunity. With the winning belief and high-spirited attitude of "starting at the beginning of the year, starting a decisive battle", they have turned a high-quality development "construction drawing" into a "real map". In order to fully show the vivid situation and brand-new look of "struggling to open a new bureau and make a good start" in the new district, and further carry forward the spirit of "starting a second business" in Binhai New Area, the media center of Binhai New Area has launched a column "Bincheng opened a new bureau to win a good start".

  Yesterday was the first working day after the Spring Festival holiday. The reporter walked into various departments, enterprises and construction sites in Binhai New Area, and a busy labor scene appeared in front of him. Everyone has said that we should start early, not take a nap, and quickly enter the working state with a full mental state to show the new year’s new atmosphere.

  The department actively serves the enterprise masses.

  At 9 o’clock yesterday morning, the government service staff in the bonded area had already sat in front of the computer. "Hello, what business do you handle?" The deputy agent wearing a "red ribbon" warmly greeted the staff of the enterprise after seeing them. After inquiry, it was learned that it was the enterprise that needed to apply for the Drainage Permit. Under the guidance of the deputy agent, the enterprise staff soon got the Drainage Permit through the "notification commitment system".

  "I thought that just after the New Year, the approval of the license would not be so fast. I didn’t expect the work efficiency of the bonded area to be so high after the year. It is so convenient for the company to get the Drainage Permit immediately by signing the letter of commitment! " The business staff said with satisfaction.

  Teng Lizhen, head of the government affairs service hall in the bonded area, said: "Although today is the first working day after the Spring Festival, the service windows of the government affairs service hall have all been opened, and the staff members are full of enthusiasm and full of energy to receive the business people who come to handle business.

  On the first day of work, the reporter learned from the District People’s Social Security Bureau that in order to seize the favorable opportunity of the Spring Festival and actively implement the relevant policies of stabilizing employment and ensuring employment, the new district began to organize a "Spring Breeze Action and Employment Assistance Month" job fair every week from January 29, and organized a live post-taking activity every month. In combination with the relevant requirements of epidemic prevention and control, offline recruitment activities were launched in a timely manner to build an efficient docking platform for employers and job seekers to help all kinds of people with employment needs get full employment. The vast number of job seekers and enterprises can log on to "Bincheng Employment Talent Network" in https://www.bhrc.com.cn to sign up.

  It is understood that the activities are mainly aimed at rural workers who are willing to work and start businesses, including rural laborers who plan to go out to work and start businesses nearby, migrant workers, workers who come to Tianjin in the pairing assistance area, all kinds of people with employment difficulties, graduates from previous universities and other job seekers, as well as employers with employment needs, especially key industrial chain supply chain enterprises.

  Enterprises strive to achieve a "good start"

  On the first day of work years later, although the festive atmosphere has not completely dissipated, all the staff of Tianjin International Biomedical Joint Research Institute quickly returned to their posts with full spirit and started a new journey in the New Year. In the laboratory on the eighth floor, several staff members in lab clothes are absorbed in the experimental operation. The R&D Center for Transformation Products of the Joint Research Institute has been deployed according to the work plan for 2023, and the annual order task has been arranged. All the staff of the center began to carry out relevant experiments in early January. "At present, the first batch of customized synthetic orders (ADC drug Liner) has been completed halfway. On the first day after the end of the Spring Festival holiday, the center staff immediately put into the experiment, made synthetic feeding, and closely connected the experimental work before the holiday to ensure that the order task was completed in an orderly manner according to the time node. " Dr. Cai Yan, director of the R&D Center for Transformation Products of the Joint Research Institute, was busy with the experiment while introducing it.

  Yesterday, the reporter learned from Lishen Battery, an enterprise in High-tech Zone, that Lishen Battery adheres to the spirit of "decisive battle is the beginning, and sprint is the beginning", and has continuously produced, stabilized and increased production, welcoming the "acceleration" of production and "a good start" of development.

  In the production workshop of Lishen battery, the PACK production department made every effort to ensure that the upcoming Dongfeng supporting power battery project was successfully delivered, and the front-line employees stuck to their posts without taking a nap and quickly put into work. From equipment inspection, commissioning, line alignment to first article confirmation and start-up production, the team cooperated tacitly, and the production rate was planned to reach 100% on the same day. The person in charge of Lishen Battery said that in the new year, the company will usher in new development opportunities and achieve new breakthroughs in scientific and technological innovation, capacity improvement and base construction. In 2023, the project is expected to produce supporting power batteries for more than 45,000 new energy vehicles.

  On the first day of work after the holiday, the dry composite film workshop, the third phase expansion project of Gaolier (Tianjin) Packaging Co., Ltd. located in Tianjin Port Free Trade Zone, showed a busy scene: the equipment was running stably, the technicians were skilled in operation, and the composite film was running smoothly on the roller … After joint acceptance, electromechanical installation and joint operation and debugging of the equipment, the project entered the trial production stage. However, the related equipment operation indexes of photovoltaic power generation projects that have just completed grid-connected power generation have also remained stable, and enterprises have enjoyed the new impetus brought by green energy.

  It is understood that Gaolier (Tianjin) Packaging Co., Ltd. belongs to Italian Gaolier Group, an industry leader in the field of flexible packaging. Since it was completed and put into operation in Tianjin Port Bonded Zone in 2006, it mainly produces composite packaging bags for liquid products and patented products in the coffee field, and is committed to providing a full range of customized packaging solutions. After more than ten years’ development, the company has all kinds of excellent packaging equipment and a complete set of quality inspection equipment, which ensures sufficient production capacity and stable quality.

  The construction site played the "Endeavour Music" for returning to work after the holiday.

On-site graders and bulldozers are advancing back and forth in an orderly manner, and the site is being leveled; Excavators and drillers are lined up in turn, and drilling is performed according to the working procedure. The company broke the practice of entering the site after the spring blossoms in previous years, implemented the project content according to local conditions, and rationally arranged and adjusted the process plan according to the temperature conditions, which greatly improved the effective utilization rate of time during the construction period.

  It is understood that in order to achieve the project construction goal, 300 workers and more than 100 sets of construction equipment have been put into work after the holiday. At present, the main construction contents of the project are bridge pile foundation construction, water supply and drainage construction, subgrade construction and temporary construction of the project.

Reporting/feedback

Why is it so "pit" that the coach is unqualified and the swimming pool is unsanitary?

  Ms. Kong’s 8-month-old child in Tianjin developed a small pimple on her stomach after swimming, and was diagnosed with contagious molluscum. She went to the hospital every one or two weeks and was completely cured in more than three months.

  With parent-child swimming becoming more and more popular with young parents, swimming like Ms. Kong’s children is infected with various diseases, and even babies are in danger of drowning. A survey by Xinhua Viewpoint reporter found that many parents-child swimming classes, which cost hundreds of thousands of dollars at a time, lack qualified coaches, and the health management of swimming pools is chaotic, and the safety of children is not guaranteed.

  Parent-child swimming blooms everywhere, and a class costs hundreds to thousands of dollars.

  A reporter from a water education early education hall in Guangzhou saw that there was a pool of about 8 square meters in the middle of the water education hall, and there were two small swimming pools next to it. There were swimming AIDS such as neck rings, pillows and underarm rings in the hall. According to the person in charge of the swimming pool, children aged 0 to 6 can come to swim.

  Parent-child swimming pools like this are blooming everywhere in major cities. The reporter visited many parent-child swimming institutions in Chengdu and Guangzhou and learned that the general courses are divided into group classes and private classes. Group class is a class where a coach leads many parents and children together, and the general charge is above 300 yuan per hour; Private classes are one-on-one teaching, and the tuition is relatively more expensive, usually thousands of dollars an hour.

  Swimming institutions offer a wide variety of courses. The Australian "WWSS" course shown to reporters by a staff member of a large parent-child swimming pool in Yuexiu District, Guangzhou, shows that through learning, the baby can strengthen the ability of primitive reflex, hand-eye coordination and learn body control and breathing control. "The goal is to let the baby really learn to swim and fall in love with swimming. Our youngest here came to class 15 days after birth. " The staff member said.

  It is understood that the courses of most parent-child swimming institutions are packaged and sold. The reporter saw in the investment list of "Yourui International Parent-child Swimming" that, taking Beijing as an example, the average unit price per class hour is 350 yuan according to the membership standard, and the average annual class hour per student is 40 class hours. Some parent-child swimming institutions in Guangzhou start selling at least 58 class hours, which means that parents invest at least about 20 thousand yuan at a time, and there are 70 thousand yuan or 80 thousand yuan in expensive class bags.

  Changing water in the swimming pool cannot be guaranteed, and auxiliary equipment can be used at will.

  Many parent-child swimming pools have advertised slogans such as "Enhance the baby’s physique from the root", "Children who swim for a long time have high immunoglobulin index in their blood", "Parent-child swimming makes babies less sick" and "Swimming is the only independent exercise that can start from the age of 0", and some institutions have also publicized the concept of "implanting foreign parent-child swimming concept".

  "Parent-child swimming is just a normal exercise. Children’s swimming can really promote development and growth to a certain extent, but it does not have those exaggerated effects. Babies under 1 year old are very weak and still in the initial development. It is not recommended to start swimming too early. " Zhu Hua, chief pediatrician of Chengdu Third People’s Hospital, said.

  Zhou Weihang, a former national swimmer, told reporters that many parents believe in the propaganda of some organizations and hope to achieve some unrealistic results through swimming. In fact, the main purpose of parent-child swimming is not to teach children to swim, but to explore each other and establish deeper parent-child feelings during swimming.

  Hygiene is the most concerned issue in parent-child swimming. Some parents reported that although many swimming pools promised to change water every day, they could not guarantee it and were not supervised. In a large parent-child swimming pool in Yuexiu District, Guangzhou, the staff said that it was disinfected and replenished with new water every day. When the reporter asked whether to change the water every day, the staff vaguely said that the whole pool is close to 100 square meters, and it will take a long time to change it all, unless there are really children urinating in it, the water will be changed temporarily. "Changing the water will affect the course arrangement, and it is very troublesome to send a notice temporarily."

  In order to prevent children from urinating in the water, the swimming pool will require children to wear waterproof diapers. The reporter saw in a parent-child swimming pool in Guangzhou that a warning paper was posted by the pool: "Any child who urinates in the pool will be fined 360 yuan." There are three children about one year old swimming in the big pool, and none of them are wearing waterproof diapers.

  There are also many bath towels in swimming pools that also have health hazards. Ms. Kong told the reporter that the child was looking for the cause of the illness after he got sick. The doctor said that the child might have been exposed to unclean bath towels. Infectious molluscum is mainly transmitted through direct contact, and many patients are infected in public bathrooms or swimming pools.

  In addition, security risks can not be ignored. Some parent-child swimming pools are quite casual in the use of baby swimming AIDS. A staff member of a swimming pool in Guangzhou told reporters that there is no uniform standard for children to use auxiliary swimming equipment. Generally, they wear neck rings for less than 6 months, pads for more than 6 months, and underarm rings for more than 2 years old.

  Zhou Weihang introduced that the neck ring is easy to cause certain damage to the child’s spine. The children’s bones did not harden six months ago, and it is easy to hurt the spine with the neck ring, which poses a safety hazard. In May last year, a July-old boy in Fuzhou drowned in a swimming pool wearing a sitting swimming ring. Fortunately, the child was not life-threatening after being sent to hospital.

  "Some informal swimming pools have misunderstandings about parent-child swimming, and the methods are more radical. They want to teach in a few months, and the curriculum is unreasonable, which does not meet the physical development of small babies." The coach of a parent-child swimming pool in Chengdu said.

  Emerging industries urgently need to establish health and safety standards.

  The reporter learned that at present, the opening of the parent-child swimming pool only needs to register a business license, and there are no standards such as health inspection and personnel requirements, and there is no clear supervision.

  Coach is an important guarantee for children’s safety. The reporter learned in the investigation that some parent-child swimming pools claim to learn from foreign countries in their coaching training methods, but many of them have no qualifications at all. "Some parent-child swimming pools have almost zero threshold for recruiting employees. Some are kindergarten aunts who are recruited to be coaches of parent-child swimming. How to ensure the safety of children?" An industry insider in Chengdu said.

  Shen Yong, head coach of a parent-child swimming pool in Guangzhou, said that there is no uniform standard for parent-child swimming pools in China at present, and it depends entirely on industry self-discipline. "For coach specifications, each swimming pool generally sets its own standards." Some standardized swimming pools require coaches to obtain lifeguard certificates and swimming social sports instructor certificates, and at the same time, they must be trained as parent-child swimming teachers for infants before they can take up their posts.

  Chen Yunde, director of the Complaints and Consultation Department of Sichuan Consumer Protection Committee, said that parent-child swimming is a new industry, and it is urgent to formulate clear standards in sanitation and disinfection, personnel qualifications and safety management to ensure the safety of infants and young children. People in the industry call for speeding up the guidance and establishment of industry self-discipline standards, such as coach training mode and the threshold for recruiting students, so as to make this emerging industry develop healthily and orderly.

  Zhu Hua and other experts said that parents should treat parent-child swimming correctly, and focus on parent-child interaction, instead of seeking to let babies learn swimming skills quickly.
