On August 10th, it was reported that Google publicly criticized Apple on the official website of Android on Tuesday, saying that it failed to improve the user experience of communication between iPhone and Android users. For a long time, some users have complained about green message bubbles in cross-device messages, such as poor compressed video quality, lack of read receipts, and other headaches. Google blames Apple for this, because the latter will convert the information sent between iPhone and Android users into SMS and MMS, both of which were developed decades ago and mainly designed for the plain text era.

Google believes that Apple should use Rich Communication Service (RSC) to realize this function. They believe that this is a "modern industry standard", which can improve users’ experience of sending text messages and making phone calls, and also support emoticons, videos and pictures. Android official website said, "These problems exist because Apple refuses to adopt modern communication standards when sending messages between iPhone and Android phones. Google also encourages visitors to share this topic on social media, including using "@ Apple" to remind Apple, and adding the topic tag of "#getthemessage". (Source: Sina Technology)

On the evening of August 10th, Beijing time, it was reported that Huang Renxun, CEO of NVIDIA, recently assured more than 22,000 employees of the company that NVIDIA would not lay off employees at least in the short term. Although the company issued a preliminary performance warning earlier, it said that its revenue in the second quarter would be lower than previously expected.

NVIDIA issued an early warning on Monday, saying that due to the sluggish game business, revenue in the second quarter is expected to be $6.7 billion, down 19% from the previous month and up 3% year-on-year. The revenue was lower than the $8.1 billion expected by NVIDIA and Wall Street analysts.

In response, Huang Renxun said in an email to employees that the performance in the second quarter was "significantly lower than expected", which was mainly due to the slowdown in the game business. But at the same time, he assured employees that the fundamentals of NVIDIA are still strong and the demand is still strong.

He said, "What does this mean for us? Will we lay off employees? No. On the contrary, we gave you a raise to take care of your families, because all of you are facing severe inflation. (Source: cnBeta)

Yesterday (December 10th), the National Health and Wellness Commission held a press conference and invited relevant experts to introduce the prevention and treatment of respiratory diseases in winter in China. What measures should schools, kindergartens and other institutions take to prevent the spread of respiratory diseases, and should they be vaccinated after they have recovered from cold symptoms? Understand the article ↓↓↓

one

The overall amount of diagnosis and treatment of respiratory diseases in children fluctuated and decreased.

Mi Feng, spokesperson of the National Health and Wellness Commission, said that at present, the overall amount of diagnosis and treatment of children’s respiratory diseases in medical institutions above the second level in the country has shown a downward trend, and the increase in pediatric diagnosis and treatment in some large children’s specialist hospitals and general hospitals has been alleviated.

Judging from the overall situation of fever clinics and emergency departments, the number of patients with respiratory diseases in China has been relatively stable in recent days, especially in primary medical institutions. The overall normal medical services in the country have not been affected.

2

What is the progress of influenza vaccination in China?

Xia Gang, director of the Department of Health and Immunity of the National Bureau for Disease Control and Prevention, said that this year’s influenza vaccine supply has the following characteristics:

First, the supply is early. Since July, vaccination units around the country have started influenza vaccination services one after another, earlier than the influenza epidemic season.

Second, the vaccine supply is sufficient. This year, the production and supply of influenza vaccine has increased significantly compared with last year, and it can meet the vaccination needs of the masses at this stage.

The third is to re-implement. Dispatch and deploy many times to guide all localities to actively promote the vaccination of influenza vaccine in accordance with the principle of informed consent.

three

What measures do key institutions and places take to prevent it?

Peng Zhibin, director of the Department of Respiratory Infectious Diseases of the Infectious Diseases Management Office of China CDC, said that schools, kindergartens, public transport and other areas are densely populated and relatively closed inside, and are key institutions and places for the prevention and control of respiratory infectious diseases.

For schools and child care institutions

First, we should vaccinate in time as soon as possible. Students, faculty and staff should carry out influenza vaccination as soon as possible to improve their own immune barrier and reduce the risk of illness;

Second, it is necessary to strengthen environmental cleanliness, maintain indoor hygiene, regularly open windows for ventilation, maintain indoor air flow, and improve classroom air quality. However, the outdoor temperature is low in winter and spring, and attention should be paid to keeping warm during window ventilation;

Third, it is suggested to strengthen health monitoring, do a good job in morning and afternoon check-ups, absenteeism registration, etc. Students and faculty members are advised not to go to work with illness to prevent infectious diseases from being introduced into schools or classrooms.

For public transport

First, it is necessary to do a good job in cleaning and disinfecting the interior of vehicles, and ventilate regularly to ensure the air quality inside vehicles;

Second, it is suggested to wear a mask in the high incidence season of respiratory infectious diseases to reduce the risk of exposure and illness and be the first person responsible for your own health.

How to strengthen protection for young children and the elderly?

Peng Zhibin introduced that winter and spring are the high season of respiratory infectious diseases, the immune system of young children is still not perfect, and the immune function of the elderly is relatively weak. On the basis of maintaining good personal hygiene habits and clean environment, it is necessary to focus on strengthening the following protective measures:

The first is to carry out vaccination as soon as possible. Vaccination can effectively reduce infection and reduce the risk of severe diseases, which is the most effective and economical means to prevent infectious diseases. Young children and the elderly should be vaccinated against COVID-19, influenza and pneumococcus as soon as possible.

Second, young children and the elderly should try to avoid going to places with closed environment and crowded people. When it is really necessary to go, they should wear masks scientifically to reduce the risk of respiratory infectious diseases.

The third is to strengthen the daily health monitoring of young children and the elderly. When there are symptoms of respiratory infectious diseases such as fever and cough, they should seek medical advice as soon as possible and use drugs scientifically and safely according to the doctor’s advice.

In addition, when other family members have respiratory infectious diseases, they should try to avoid close contact, especially to avoid contact with young children and the elderly at home. When children whose family members have symptoms of respiratory infectious diseases such as fever and cough go to the hospital, they should also protect themselves and avoid cross-infection.

five

Are you still vaccinated after you have recovered from cold symptoms?

Xia Gang, director of the Department of Health and Immunity of the National Bureau for Disease Control and Prevention, said that if flu-like symptoms have already appeared, it is recommended to continue to vaccinate against influenza after the diagnosis is not confirmed and self-healing. There are two reasons:

First, the symptoms of respiratory tract infection are not specific, and many pathogenic infections may have flu-like symptoms such as fever and headache. However, such symptoms are not necessarily infected with influenza virus, but may also be infected with other pathogens, the most common being the common cold.

Second, there are many types (except A, there are B) and subtypes (A has H1N1 subtype and H3N2 subtype) of influenza virus, which can cause epidemic. After being infected with a certain type or subtype, there will be the risk of getting other types or subtypes of influenza. Influenza vaccine is a multivalent vaccine covering many different types and subtypes, and trivalent and tetravalent vaccines are usually used. If you are vaccinated after being infected with a certain type of influenza (such as A), the components of other types of influenza (such as B) contained in it can still play a role in preventing this type of influenza. In addition, in the same epidemic season, different types and subtypes are commonly prevalent. For example, at present, subtype A (H3N2) is dominant, followed by influenza B.. In the past, in the same epidemic season, the dominant strains gradually changed from one type to another.

Therefore, even if you have had cold symptoms recently, it is recommended to get flu vaccine as soon as possible after recovery, especially for key people such as the elderly. Vaccination with flu vaccine can reduce infection and reduce the risk of serious illness and death.

six

On the effectiveness and safety of influenza vaccine

Peng Zhibin, director of the Department of Respiratory Infectious Diseases of the Infectious Diseases Management Office of China CDC, said that people’s understanding of the harmfulness of diseases, the safety and effectiveness of vaccines all affect their willingness to vaccinate. Peng Zhibin responded to three questions at the press conference:

First of all, about the dangers of influenza. Influenza is not a common cold, but an acute respiratory infectious disease caused by influenza virus. People are generally susceptible to influenza virus, and high-risk groups such as infants, the elderly and patients with chronic diseases are more harmful after being infected with influenza, and may have serious complications such as pneumonia.

Secondly, about the effectiveness of influenza vaccine. Scientific research and vaccination practice have fully proved that influenza vaccination is effective. For the elderly who are at high risk of becoming seriously ill after being infected with influenza, influenza vaccination can effectively reduce the incidence of influenza and the incidence of influenza-related complications in the elderly. Some researchers have made a comprehensive analysis of 95 studies on the protection effect of influenza vaccine in the world. The results show that in the flu season, after the elderly are vaccinated with influenza vaccine, the flu-like symptoms can be reduced by 39%, the confirmed flu can be reduced by 49%, and the flu-related complications can be reduced by 28%.

Taking another key population, children and adolescents, as an example, influenza vaccination can effectively reduce the incidence of influenza in school-age children, and can also reduce absenteeism from school due to influenza. Research conducted in Beijing shows that large-scale centralized vaccination of influenza vaccine for primary and secondary school students can reduce the risk of influenza concentrated fever by 50%-89%. The research carried out in Shenzhen shows that the high vaccination rate of influenza vaccine can effectively reduce the risk of absenteeism, and the preventive effect on absenteeism is 53%.

Third, about the safety of vaccines. Influenza vaccine has been used in the world and China for decades. It is a mature vaccine with good safety.

seven

These vaccines are also recommended for key populations.

Xia Gang said that in addition to influenza vaccination this winter and next spring, pneumococcal vaccine and Covid-19 vaccine are also recommended for the elderly and people with chronic basic diseases;

For children, it is suggested that on the basis of continuing to do a good job in immunization planning vaccination, non-immunization planning vaccines such as pneumococcal vaccine and Haemophilus influenzae type B conjugate vaccine can also be vaccinated.

No matter whether it is an immunization program vaccine or a non-immunization program vaccine, the requirements of vaccination specifications should be strictly followed during the vaccination process.

Original grumpy little doctor Tencent medical code　

In Chinese over 60 years old, osteoporosis has reached 56%[1].

However, there is one disease that is more frequent than it-senile foot disease, the prevalence rate is as high as 87%, which seriously threatens the health of our parents [2,3].

However, only 7.3% people will take foot disease seriously and consult a doctor [4].

As the saying goes, "people get old when they are old", and when they get old, their legs and feet are awkward at first.

Time and tide wait for no man

With the increase of age, the muscle strength of the foot is weakened, the elasticity of ligaments becomes worse, or due to unsuitable shoes, it is easy to have problems such as arch collapse and hallux valgus [1-3]. As a result, the load-bearing capacity of both feet decreases.

(Made by myself)

2. Poor foot care

Old people, bad eyes, inflexible fingers, and inability to bend over will all lead to a common result-

Give up the care of your feet.

(Made by myself)

If the toenails are too long to be trimmed or washed, it may lead to problems such as too long and thick toenails and onychomycosis.

The most common foot diseases of the elderly are [6]:

Hypertrophy of toenails (41.3%)

Hallux valgus (commonly known as "big foot bone") (28.7%)

Dry skin (26.0%)

Corns and calluses (commonly known as calluses) (24.0%)

These problems will lead to a common consequence-

If you can’t walk steadily, you will fall easily.

Many elderly people are relatively fat, and their feet are heavily burdened when walking, which makes them easy to hurt, increasing the risk of falls and fractures.

Moreover, osteoporosis is a common disease in the elderly, and it is more likely to lead to hip fracture when falling-it is called "the last fracture in life" (the mortality rate of hip fracture is as high as 22%~30%, even 50%[7-9]).

American gerontologist Hazzard said: "A clear head and a pair of feet that can move freely can make the elderly live better." [5]

Inappropriate shoes are one of the reasons why the elderly fall, and more than 70% of the elderly have inappropriate shoes [10]. So, what are the main situations in which shoes are not suitable?

1. The shoes are too narrow

Toes and soles are squeezed for a long time, so that the forefoot is deformed, hallux valgus and little toe are deformed, which will be very painful.

(Made by myself)

2. The shoes are too short

It will bend the toes, which will be deformed after a long time (that is, hammer toes or claw toes).

(Made by myself)

The skin on the instep is squeezed, slowly forming a hard cocoon, which is painful and swollen.

Diabetic elderly people with poor blood sugar control are also prone to serious infections.

Let me say one thing first:

The so-called "shoes for the elderly" should be bought carefully to avoid paying the "filial piety tax".

Many "shoes for the elderly" are branded as breathable, spacious, soft, non-squeezing, and non-slip, and can even be like twisting a towel.

(Made by myself)

But in fact, the softer the shoes, the better. Shoes that can be easily twisted are easy to deform and lack support for the arch.

When buying shoes for the elderly, we should follow the principle of "wide front, tough middle and hard heel".

Specifically, the elderly should pay attention to these three points when choosing shoes:

1. The sole has anti-slip design.

Older people’s physical balance ability becomes worse, and the perception of pressure on the soles of their feet decreases, which will increase the risk of falling when walking [5].

Therefore, it is necessary to choose a non-slip design for the sole.

2. Hard soles with sufficient support

Shoes that are too soft, such as old cloth shoes, lack sufficient support at the arch, and it is easy to feel uncomfortable when walking too much, and the feet are tired, sore and painful; Encountering a gravel road will also increase the risk of falling [11,12].

Hard-soled shoes can increase the safety and stability of the elderly when walking [13].

The middle toughness of shoes should be moderate, and you can try to twist them by hand. It is not good to twist them too easily or completely.

The heel also needs to have a certain height, at least 1.5~2.5 cm, which can disperse the pressure on the sole of the foot.

3. The vamp should be breathable, warm and loose.

Old people’s feet have poor blood circulation and are prone to cold feet, pain, blue skin and other symptoms [11].

Buying a pair of breathable, warm and loose shoes is comfortable and easy to wear, and it can also reduce the incidence of nail malnutrition and fungal infection (commonly known as beriberi) [5].

It can be a little bigger, leaving about 1 cm in front of the toes, so that the toes have enough room to move.

In addition, when the elderly buy shoes, there are three tips:

1. It’s best not to buy it by children or online shopping, but to try it yourself.

Bring socks and insoles that you usually wear. Feel it on your feet and experience walking, running and jumping in the store to choose the shoes that suit you best.

It’s best to buy it in the afternoon

Affected by gravity and venous reflux, people’s feet are usually bigger in the afternoon than in the morning.

Trying on shoes in the morning will hurt your feet in the afternoon [5].

Don’t bother, try more pairs.

Old people often encounter two feet with different sizes, for example, one foot has severe hallux valgus, or the arch of both feet collapses to different degrees.

This requires trying on a few more pairs and finding shoes that are comfortable for both feet. Or put an arch support pad on a shoe.

WU

noon

Dragon Boat Festival is one of the four traditional festivals in China.

Celebrate every year on the fifth day of the fifth lunar month.

The origins and customs are rich and varied.

Has profound cultural connotation.

The origin of Duanwu Festival

It is said that the custom of eating zongzi and racing dragon boats on the Dragon Boat Festival is to commemorate Qu Yuan, a great poet in Chinese history. It is precisely because of this that the Dragon Boat Festival was named "Poet’s Day" after the founding of New China.

In the history of our country, the saying that the Dragon Boat Festival is to commemorate Qu Yuan has a history of more than 1500 years. According to legend, after Qu Yuan threw himself into the Miluo River, the local people immediately rowed for rescue and went all the way to Dongting Lake, but Qu Yuan’s body was never seen. At that time, it was rainy, and the boats on the lake gathered together beside the pavilion on the shore. When people learned that it was to salvage the virtuous minister Dr. Qu, they went out in the rain again and rushed into the vast Dongting Lake. In order to mourn, people rowed on rivers, and then it gradually developed into a dragon boat race. The people were afraid that the fish in the river would eat his body, so they went home to bring rice balls and throw them into the river to prevent fish and shrimp from ruining Qu Yuan’s body. Later, it became the custom to eat zongzi.

dragon boat race

Dragon boat race is the main custom of the Dragon Boat Festival. According to legend, it originated in ancient times, because Chu people could not bear to part with Qu Yuan, a worthy minister, and died in the river, many people rowed to catch up and save. They scrambled to catch up with each other until Dongting Lake disappeared. After that, I will row a dragon boat on May 5th every year to commemorate it. People use dragon boats to disperse the fish in the river so as not to eat Qu Yuan’s body. The habit of racing is prevalent in Wu, Yue and Chu.

eat Zongzi

Eating zongzi on Dragon Boat Festival is another traditional custom of Chinese residents. Zongzi, also known as "horn millet" and "tube zongzi". It has a long history and various patterns. On the morning of Dragon Boat Festival, families eat zongzi to commemorate Qu Yuan. Generally, they wrap zongzi the day before, cook them at night and eat them in the morning. Dumplings are mainly made of tender reed leaves which are abundant along the river pond, and bamboo leaves are also useful in some areas, collectively called zongye. The traditional form of zongzi is triangle, which is generally named after the inner pulp. The glutinous rice dumplings are called rice dumplings, the ones mixed with adzuki beans are called adzuki dumplings, and the ones mixed with red dates are called jujube dumplings, which are collectively called glutinous rice dumplings. Jujube dumplings are homophonic for "early middle school", so they are eaten the most, and children who intend to study can win the championship early. In the past, scholars used to eat jujube dumplings in the morning on the day of taking the imperial examination. Up to now, parents have to make jujube dumplings for candidates on the morning of the entrance examination day for middle schools and universities, wishing them a good school.

Tie colorful ropes and wear sachets.

Five-color lines are mainly composed of five colors: green, red, white, black and yellow. These five colors are called auspicious colors, and they can be worn on the Dragon Boat Festival to keep you safe. Later, the custom of tying colorful ropes gradually evolved into hanging sachets, and children wore sachets on the Dragon Boat Festival. Legend has it that it meant to ward off evil spirits and drive away plague (in ancient times, people thought that they were sick because of monsters and ghosts), but it was actually used to decorate the inner head. The sachet contains cinnabar, realgar and fragrant medicine, wrapped with silk cloth, which is full of fragrance, and then tied with five-color silk threads to form a rope, making a string in various shapes, all kinds of shapes, small and lovely. In some southern cities of China, young men and women also use sachets to express their deep love.

Hanging wormwood and calamus

A folk proverb says, "Willows are inserted in Qingming Festival, and Ai is inserted in Dragon Boat Festival". On the Dragon Boat Festival, people regard inserting wormwood and calamus as one of the important contents. Every household should sweep the courtyard and put calamus and moxa sticks in the lintel and hang them in the hall. Acorus calamus, Folium Artemisiae Argyi, Liuhua, Bulbus Allii and Dragon Boat Flower are made into human or tiger shapes, which are called Ai Ren and Ai Hu. It is made into garlands and ornaments, which are beautiful and fragrant, and women compete to wear them to drive away evil. Dragon Boat Festival is also a "health festival" handed down from ancient times. On this day, people sweep the courtyard, hang mugwort, hang calamus, sprinkle realgar water, drink realgar wine, stir up turbidity, remove rot, sterilize and prevent diseases. They are considered to have the effect of exorcising evil spirits and protecting the health and safety of family members.

Point realgar wine

Realgar is also a kind of medicinal material, which is said to kill all kinds of poisons. Therefore, during the Dragon Boat Festival, Shaanxi people will soak realgar in wine and put realgar wine on children’s ears, nose, forehead, wrists and ankles. It is said that this practice can keep mosquitoes, snakes, scorpions, centipedes, geckos and spiders off their bodies.

Eating salted duck eggs on the Dragon Boat Festival is a big custom. As the saying goes, "You have to eat salted egg zongzi to send the chill." After the Dragon Boat Festival, it indicates that the hot summer is coming, and the activities of animals and plants have entered a vigorous stage.

　　The central bank conducted a 7-day reverse repurchase operation of 2 billion yuan today.

　　On April 18th, the central bank conducted a 7-day reverse repurchase operation of 2 billion yuan today, and the winning bid rate was 1.8%, which was the same as before. () iFinD data shows that there are 2 billion yuan of 7-day reverse repurchase due today, so zero delivery and zero return were realized on the same day.

　　The central bank responds whether the real interest rate is too high: different industries and enterprises feel differently, so as to prevent the involution competition from intensifying due to the low interest rate.

　　Zou Lan, director of the Monetary Policy Department of the People’s Bank of China, said that the situation of prices and real interest rates still needs to be comprehensively judged. The current low price is structural and phased. From the structural situation of prices, CPI, PPI, average interest rate of loans, etc. are all average concepts. There are differences in loan interest rates of different industries and enterprises, and the fluctuation range of product prices is different, so the real interest rate is different. The central bank will continue to closely observe the situation of economic recovery and economic transformation. It should not only keep the nominal interest rate at a reasonable level, consolidate the trend of economic recovery, but also fully consider the needs of high-quality development, avoid cutting the kinetic energy of structural adjustment, and prevent low interest rates from intensifying involution competition and idling funds, which will further reduce prices and form a bad cycle with each other. (Securities Times)

　　Central Bank: In the first quarter, medium and long-term real estate loans increased by 672.7 billion yuan, and the growth rate rebounded.

　　The State Council Office held a press conference on the financial operation and foreign exchange receipts and payments in the first quarter of 2024. Zhang Wenhong, head of the Survey and Statistics Department of the People’s Bank of China, said that new loans in the first quarter were mainly invested in key areas such as manufacturing, infrastructure and service industries, and the growth rate of loans in the real estate industry also picked up. Among them, the growth rate of medium and long-term loans in the real estate industry has increased. At the end of March, the medium and long-term loans in the real estate industry increased by 4.9%, 0.6 percentage points higher than the end of last year, and the cumulative increase in the first quarter was 672.7 billion yuan, which was higher than the same period of last year.

　　The central bank talks about M2 exceeding 300 trillion yuan: it is not appropriate to make simple comparison in the same period, and the monitoring of fund idling will be strengthened.

　　According to the Securities Times, Zou Lan, director of the Monetary Policy Department of the People’s Bank of China, said at the press conference of the State Council Office that the current broad money (M2) exceeds 300 trillion yuan, which is a reflection of financial support for the development of the real economy in the past years. Generally speaking, the current stock currency is indeed not low. At present, China’s economic restructuring is accelerating, the economy is lighter, the credit demand is weaker than before, and the credit structure is optimized and upgraded. However, all parties have a process of understanding and adapting to this change, and some banks still have "scale plots" in internal assessment, which exceeds the effective financing needs of the real economy; Some enterprises rely on their dominant position to buy wealth management or lend money to other enterprises with low-cost loans. The main business does not make money, but finance becomes the main business, which is easy to form idling and capital precipitation, reducing the efficiency of capital use. Relevant departments will strengthen the monitoring of fund idling and improve the management assessment mechanism. In the future, with the economic transformation and upgrading, the effective financing demand will be restored, the social expectation will be improved, and the phenomenon of fund precipitation idling will also be alleviated. At present, the huge monetary aggregate growth may slow down, and the data will be disturbed, so it is not appropriate to make a simple comparison in the same period.

　　Central Bank Zhu Hexin: The central bank’s goal and determination to maintain the basic stability of the RMB exchange rate will not change.

　　Zhu Hexin, deputy governor of the People’s Bank of China and director of the State Administration of Foreign Exchange, said that since the beginning of this year, the market has repeatedly expected the shift of the Fed’s monetary policy, the turmoil in the international financial market has intensified, and the exchange rate fluctuations of some currencies have increased. Although the exchange rate of RMB against the US dollar has also fluctuated, it has appreciated against a basket of currencies on a stable basis. In the short term, the economy made a good start in the first quarter, and the positive factors increased, which was conducive to hedging external disturbance factors and supported the RMB exchange rate. The RMB exchange rate remained basically stable on both macro and micro levels. In the next step, the central bank will focus on me, give consideration to internal and external balance, and adhere to a managed floating exchange rate system based on market supply and demand with reference to a basket of currencies; Pay close attention to the changes in the foreign exchange market, continue to make comprehensive policies and stabilize expectations, resolutely correct procyclical behaviors, resolutely guard against the risk of exchange rate overshoot, and keep the RMB exchange rate basically stable at a balanced level. (Securities Times)

　　Zhang Wenhong, the central bank: Although the scale of new social financing in the first quarter has declined year-on-year, it is still at a high level in history.

　　According to the Securities Times, on April 18th, Zhang Wenhong, head of the Survey and Statistics Department of the People’s Bank of China, said at the press conference of the State Council Office that the growth rate of social financing scale in the first quarter basically matched the expected targets of economic growth and price level, especially on the basis of last year’s high base, the growth rate of social financing of 8.7% was actually not low. Since the beginning of this year, the People’s Bank of China has paid more attention to guiding the balanced growth of financial institutions. Although the scale of new social financing in the first quarter has dropped year-on-year, it is still at a high level in history.

　　Central Bank: Promote the further marketization of deposit and loan interest rates, and stabilize the debt cost and net interest margin of banks.

　　The central bank issued a document in the People’s Daily, saying that the internal and external balance should be taken into account, and the prices of interest rates and exchange rates should be well coordinated. In terms of interest rates, it is necessary to improve the formation, regulation and transmission mechanism of market-oriented interest rates, promote the further marketization of deposit and loan interest rates, stabilize bank debt costs and net interest margins, and improve the sustainability of financial institutions supporting the real economy. On the exchange rate, we should insist that the RMB exchange rate is mainly determined by the market, and at the same time resolutely correct the procyclical behavior, prevent the risk of exchange rate overshoot, prevent the formation of unilateral consensus expectations and self-strengthen, and keep the RMB exchange rate level basically stable.

　　Ministry of Industry and Information Technology: Accelerate the layout of the industrial chain around innovation chain’s low-altitude economic development and accelerate the technical research and model innovation of low-altitude Zhilian.

　　Shan Zhongde, vice minister of the Ministry of Industry and Information Technology, said that we should make full use of enabling technologies such as the new generation of information and communication technologies, accelerate the technological research and model innovation of low-altitude Zhilian, and provide solid support for building a safe and efficient low-altitude operation system in the future.

　　The vegetation is lush, the rice is fragrant, and it goes to Duanyang.

　　The Dragon Boat Festival, a traditional festival that has lasted for thousands of years, bears the heavy feelings of the Chinese nation for home and country.

　　"Patriotism is the deepest and most lasting emotion in the world." "For every Chinese, patriotism is a duty and a duty, where the heart belongs and the feelings belong" … … General Secretary of the Supreme Leader has made many important expositions on patriotism, stressing the need to learn the "four histories" well and cultivate the feelings of loving the Party, patriotism and socialism.

　　This year’s Dragon Boat Festival, we are about to celebrate the centenary birthday of the Communist Party of China (CPC). The journey of a hundred years is magnificent, and the initial heart of a hundred years lasts for a long time. Let’s appreciate the profound feelings of home and country from several stories about "taste".

　　In August 1920, the first Chinese translation of the communist party Declaration was translated by Chen Wangdao and officially published in Shanghai. This booklet has guided a large number of people with lofty ideals to set up lofty ideals of communism and devote themselves to the cause of national liberation and rejuvenation, which has had an important impact on the birth of the Communist Party of China (CPC) and the victory of the China Revolution.

　　In the humble woodshed, a plank was placed on two long benches as a table … … In order to translate the communist party Declaration well, Chen Wangdao, who is proficient in English and Japanese, spent several times as much energy as usual. Once, because he was too focused, he mistook the ink for brown sugar and dipped it in zongzi, and said, "It’s so sweet." This leads to a sentence: the taste of truth is very sweet.

　　On November 29th, 2012, General Secretary of the Supreme Leader told the story of Chen Wangdao’s translation of the communist party Declaration when he visited the exhibition Road to Rejuvenation.

　　△ On June 3rd, 2021, the Memorial Hall of the First National Congress of communist party, China was newly opened. The picture shows the first and second editions of the communist party Declaration in August and September, 1920.

　　Everything goes forward, and we must not forget the road we have traveled; No matter how far you go, you can’t forget the past and why you set out.

　　"Now, it is very meaningful for you to actively preach the story of the old headmaster Comrade Chen Wangdao’s pursuit of truth and spread Marxist theory. I hope you will keep doing it and do it better … …” On June 27th, 2020, the Supreme Leader wrote back to all the members of the party member Volunteer Service Team in Fudan University’s communist party Declaration Exhibition Hall, and raised ardent expectations for party member, especially the young party member.

　　Generations of the Communist Party of China (CPC) people have planted patriotic feelings, so that the red gene and revolution can be passed down from generation to generation.

　　"share the blessings with the masses, share the difficulties, have salt with salt, and have no salt with light." On February 20, 2021, General Secretary of the Supreme Leader stressed at the mobilization meeting of Party history study and education that it is necessary to educate and guide the whole party to deeply understand the nature and purpose of the party, insist on doing everything for the people and relying on the people, always put the people in the highest position in their hearts and take the people’s yearning for a better life as their goal.

　　At that time, the Kuomintang reactionaries imposed an economic blockade on the Central Soviet Area in an attempt to prevent "a grain of rice, a pinch of salt and a spoonful of water" from entering the Soviet Area.

　　In the face of difficulties, the villagers frequently resorted to clever tricks, either breaking through the joints of the bamboo poles and loading salt, or soaking clothes with salt water, or even pretending to be beggars, and simply transported salt to the Soviet area. The villagers stepped over many obstacles and risked their lives to help the Red Army out of difficulties. The reason is that the Red Army insists that "salt is the same as salt, and no salt is the same as light" and vows that "as long as the Red Army has salt to eat, the dishes and bowls of ordinary people must be salty".

　　In the winter of 1928, the Red Army seized salt from local tyrants and distributed it to the villagers. Li Shangfa, a villager, was given salt, so he didn’t want to eat it and wanted to leave it to the Red Army. In order to prevent this precious salt jar from falling into the enemy’s hands, he quietly buried the salt jar in the tree hole behind his house. This hiding is 31 years.

　　△ At the Jinggangshan Revolutionary Museum, Li Qiude introduced the salt cans donated by his grandfather Li Shangfa.

　　Today, this brown clay pot is quietly displayed in Jinggangshan Revolutionary Museum, and the salt in it has turned black and crystallized.

　　"Salt is the same as salt, and no salt is the same as light", which vividly explains the initial mission of communist party people and profoundly demonstrates the flesh-and-blood ties between our party and the people.

　　Frogs sing and birds sing, and rice flowers are fragrant.

　　　 [Original Truck House] With the increasingly fierce competition in the domestic industry, various car companies have successively launched their own flagship brands in recent years. As a member of the heavy truck industry, I finally can’t make more tricks in the cab of Isuzu. So it came into being.

　　　 In fact, Ou Man GTL imitated it, and everyone knows this. We don’t have to judge whether it is good or not too much. After all, domestic car companies basically do this. As users, we pay more attention to the effect of use, and expect Ou Man GTL to give us a perfect answer.

　　　 In this article, we will show Ou Man GTL to you in more graphic ways. Please pay attention to other contents of Truck House about Ou Man GTL.

●　 The meaning of GTL in Ou Man

　　　 The three letters of GTL contain many meanings, such as "Global Technology Leader" (that is, world technology leader); It can also be interpreted as "Green Transport Landmark" (that is, a milestone of green transport); It can also be understood as "Gas To Liquid" (that is, natural gas synthetic oil, also known as "green dye"), but these explanations are not completely correct. In the special issue of the Mid-year Business Meeting in Ou Man, the product positioning and brand meaning of GTL were introduced in detail.

Ou Man GTL Product Positioning and Brand Meaning

●　 Ou Man GTL Appearance: Inheriting Ou Man Family Face.

　　　 As early as 2003, Ou Man began to design a new generation of cab. After seven years, Foton Motor made its debut in the GTL of Ou Man at the 2010 Beijing Auto Show. From the renderings to today’s production cars, it has made a qualitative leap. At last year’s annual meeting in Ou Man, we learned that Ou Man GTL cab can be divided into two types: flat floor cab and stepped floor cab. In addition, there is a single-row, flat-topped daytime cab. We only introduce the Ou Man GTL of the stepped floor cab here.

　　　 1. The air intake grille is upgraded without losing the family blood.

　　　 The air intake grille follows the style of Ou Man family, strengthens the brand characteristics, and is very harmonious as a whole, tough and delicate.

　　　 2. The new LOGO is more recognizable.

　　　 Ou Man GTL launched the brand-new LOGO of Foton Motor. From the appearance, the new LOGO is more distinctive and the recognition from a long distance has been improved a lot.

　　　 3. Bumper design is not well thought out

　　　 The drag hook is hidden behind the license plate frame, and the license plate can be turned down when in use; Only the lower pedal on the front bumper can stand people, and it has also been treated as anti-skid, while the upper pedal has not been treated at all. This makes it difficult to wipe the glass in daily driving.

　　　 4. Headlights with electric adjustment are rare.

　　　 GTL lighting in Ou Man adopts integrated headlights with lenses. It is commendable that its headlights have adjustable function, and the driver can adjust the illumination height of the lights inside the cab according to the weight of the cargo. This is the first time for domestic commercial vehicle manufacturers.

　　　 5. The front mask opening device has mixed opinions.

　　　 The opening device of Ou Man GTL front face mask is set on the front face, which means that the face mask can be opened without being in the cab. There may be different opinions about this design. However, Xiao Bian believes that even if it is opened, there is nothing to steal.

　　　 6. Modular design of pipeline layout-simplicity

　　　 When the mask is opened, it can be seen that the pipeline layout of GTL in Ou Man is in accordance with the modular design, and the cab adopts a four-point suspension airbag body suspension system to ensure the driver’s comfort during driving. Of course, the cab intake filter device, as a high-end model, is indispensable.

　　　 7. With a chrome-plated cover on the whistle, Fukuda is very kind.

　　　 The whistle is overhead, and a chrome-plated cover is added at the front end of the whistle, which also shows Ou Man’s "kindness" in workmanship. Its function is to prevent mosquitoes and rainwater from entering the whistle.

　　　 8. Ou Man GTL original fairing is quite powerful.

　　　 I feel that the work and quality of the spoiler components assembled on GTL in Ou Man are quite reliable, so I have specially "studied" them. The side plate of the spoiler can be folded inward, which is convenient for the driver to board the workbench for maintenance and operation.

●　 Ou Man GTL Interior: "Salute" to Mercedes-Benz Actros

　　　 Compared with the previous generation, the cab of GTL in Ou Man has been greatly improved in terms of internal space and comfort. Its interior is basically referenced, but some minor changes have been made in local positions. If it weren’t for the sign of Ou Man on the steering wheel, I would really think I got into an "improved" Actros. Let’s first test you with two pictures.

　　　 From the picture above, can you tell me which one is Ou Man GTL? Let me tell you, yes, it’s the picture on the left.

　　　 1. The cab layout imitates Mercedes-Benz Actros.

　　　 The main color of the cab is dark gray, and the local position is decorated with silver. Although the divisions of various functional areas have been slightly modified, it can still be seen that this is a replica of Mercedes-Benz Actros. If it weren’t for Fukuda’s LOGO on the steering wheel, I really thought I got into a Mercedes-Benz Actros.

　　　 2. High-end models can choose multi-function steering wheel.

　　　 The four steering wheels are designed with reference to Mercedes-Benz Actros, but the LOGO in the middle is changed to Fukuda’s. The steering wheel can be adjusted in four directions, and high-end models can also be equipped with a multi-function steering wheel, which can realize functions such as cruise control and volume increase and decrease of car stereo.

　　　 3. The top design is remarkable

　　　 A storage box, a player and some control buttons are designed in the front position inside the cab. As the flagship brand of Futian heavy truck, a skylight with insect-proof net is indispensable.

　　　 4. Standard (optional) airbag cushion seat to improve driving comfort.

　　　 The seat adopts airbag shock absorption, and the cab is suspended at four points. The driver’s driving comfort should be greatly improved, because it has not been measured and we are not sure. The right area of the seat is the gear lever and the parking brake operating switch.

　　　 5. The key layout is within reach.

　　　 The control buttons on the panel are all within reach, and the driver’s left-hand area is mainly designed with light height adjustment and backlight switch; The upper area on the driver’s right hand side is mainly composed of air conditioning knobs and control buttons; The lower area is the storage box and the cup holder.

　　　 6. The door design is simple, which improves the comfort of the legs when driving.

　　　 The lower part of the door is "clean" and there are not so many complicated settings, which makes the driver’s leg position more comfortable when driving. The driver’s door armrest integrates electric glass control, central locking, rearview mirror adjustment button, and high-end models are also equipped with mirror preheating function. The air outlet is spherical and can rotate 360 degrees or be completely closed.

　　　 7. Equipped with two power output interfaces with different voltages.

　　　 At the top of the center console, a trapezoidal storage box is designed, which can usually put some sundries. The air outlet and sundries box of the air conditioner are designed in the middle position, while in the lower position, besides the storage box, there are two power output interfaces with output voltages of 12V and 24V respectively.

　　　 8. Sleeper has more storage space.

　　　 As a driver’s other home, it is also important to rest during daily driving. Ou Man GTL high-top cab adopts double-deck sleeper. The left and right sides of the sleeper are equipped with storage boxes, reading lights and air conditioning outlets. The left side of the sleeper (driver’s side) is also equipped with keys such as cab light switch and air conditioning adjustment. The lower berth is divided into three independent storage boxes with partitions to facilitate the placement of tools.

　　　 9. The interior space is very spacious.

　　　 Ou Man GTL also has a major feature, and the drop of its internal stepped floor is very small. That is to say, the internal space is much larger than that of other domestic stepped floor models.

●　 Introduction of GTL chassis in Ou Man

　　　 The previous Fukuda Ou Man series models have always had the reputation of "no major faults, but no minor faults". Whether the appearance of GTL in Ou Man will change the brand image of Foton Ou Man Car Department is still unknown, and it is not easy to jump to conclusions. However, I am looking forward to Ou Man GTL giving us a good answer.

　　　 1. We will introduce some of them to you after the new car comes on the market.

　　　 2. The functional areas of the chassis are arranged compactly.

　　　 The Ou Man GTL we saw at the meeting place today is designed with a lightweight chassis. The front and rear steel plates are made of few leaf springs, and the front and rear axles are equipped with transverse stabilizer bars. The exhaust pipe, air storage tank, storage battery and urea tank are unknown from front to back on the left side of the car body; The right position is equipped with a largeCapacity fuel tankIt is worth mentioning that Ou Man GTL fuel tank is equipped with an independent heat source system, that is, a diesel boiler. Unfortunately, the oil-fired boiler assembled by GTL in Ou Man can only provide heating for the cab, but it cannot realize the preheating function of the water circulation system.

　　　 3. Saddle is adjustable and pipeline protection is in place.

　　　 The reserved hole on the girder allows the user to adjust the position of the saddle according to the requirements. The layout and protection of each pipeline are also in place.

●　 Editor’s note:

　　　 I believe there will be many different voices when Ou Man GTL goes public. However, judging from the appearance and interior design we saw today, the design of Ou Man GTL still took a lot of effort, and there is no complete "painting a tiger according to a cat". From the point of view of exterior modeling and interior coordination, it has greatly improved compared with previous Ou Man series models. However, we are more concerned about the performance of Ou Man GTL in future use. I hope this answer sheet can give us a satisfactory answer.

　　　 What do you think of GTL in Ou Man? Welcome to discuss with us.

　　No ability to coach, no time to coach, neither time nor ability to coach.

　　This spring, primary and secondary school students all over the country experienced a great learning migration. Once lively playgrounds and classrooms were silent, familiar deskmate teachers met online, and familiar blackboard books became electronic courseware.

　　With the arrival of the new semester, it is foreseeable that online classes will change from "freshness" to "new normal". From the first online course in Beijing 101 Middle School in 1996 to the present, all primary and secondary school students in China are online, and online education has been growing and popularizing. But at the same time, people also put forward higher requirements for online education. Online education also needs "self-evolution" on how to take educational value as the cornerstone and make full use of new technologies to improve students’ efficiency and reduce burdens.

　　"Self-evolution" of Good Teachers: From Fuzzy Experience to Accurate Data

　　What is a good teacher? The standards of each era are not the same.

　　In the past, a good teacher must have a solid classroom foundation and rich teaching experience. Grading homework and grading papers all the year round, so that they can walk the rivers and lakes with years of experience like old Chinese medicine practitioners. But in the era of online education, everything is changing gradually.

　　In the eyes of Liu Chang, the principal of the online school of learning together, students’ learning data has become the key to driving the whole teaching process. In the past, famous teachers relied on years of teaching experience, and one or two students could teach accurately according to their children’s learning characteristics. But once the number of students in the class is large, it is difficult for teachers to train according to the characteristics of each student. As a result, some children "do not have enough to eat" and some "can’t digest" in class.

　　"To a certain extent, this situation forces parents to sign up their children for off-campus training institutions."

　　Liu Chang believes that in order to solve the above problems, we must use information technology. Let each student learn data to form a user portrait, which is the key to drive the whole system to learn and improve continuously. Students produce a large number of data records in the daily learning process. Offline data can also be converted into online data through technologies such as photo correction and oral evaluation, and then analyzed through artificial intelligence technologies such as deep learning and data mining, so as to grasp the real learning situation of students.

　　Liu Chang believes that only when students learn data to drive real accurate teaching and bid farewell to "experiential" teaching can we truly "teach students in accordance with their aptitude".

　　In the front line of education, informatization has gradually penetrated into all aspects of learning. In the summer school of online school together, before each class starts, the lecturer will click on the students’ learning situation report to check the students’ weaknesses, and then design the specific content of this class to ensure targeted one-on-one explanation. After-class exercises will also be personalized according to the characteristics of students, so as to truly understand and master.

　　Obviously, a good teacher in the new era will gradually move from experience-based to data-based, and how to make better use of this information system and design a learning path for his students will become a standard to define a good teacher in the future.

　　"Self-evolution" of Good Tutoring: From Supervisor to Learning Companion

　　The parents of a student at Chengguan Primary School in Ganxian District, Ganzhou City, Jiangxi Province, have been running around for work all the year round. When he was young, he suffered from a low level of education, and he was unwilling to let his children go back to their old ways.

　　"Double-income workers like us have no time for counseling, and in the senior grades of primary school, I can’t do many questions. How can I help? Who will coach? " The parent said with emotion.

　　According to survey data, in China families, the difficulties parents encounter in their children’s extracurricular tutoring can be roughly divided into three types: no ability to tutor, no time to tutor, and neither time nor ability to tutor.

　　In essence, the tutor of the online school plays the role of the subject head teacher, taking the students to preview before class, following the students in class, and writing down the difficult points that the students feedback in the chat area. Although there is no need to make courseware, the tutor must also go deep into the subject system, knowledge points and test sites.

　　After class, the tutor can see the progress and accuracy of the exercises submitted by students in real time through the background, and give solutions to the weaknesses of different children.

　　How to be targeted and personalized? To this end, the online school of learning together launched the "Bian Que System" this year, which uses big data tools and teaching evaluation to make a systematic analysis of students’ homework, weekly test, monthly test and big test.

　　Tutors can learn about the weak links of specific students according to the evaluation situation and launch personalized education services. Different students in the same class may open the page of homework assignment, and the content may be completely different. Let the invalid and repetitive homework be greatly reduced, and the time for writing homework will also be shortened, thus reducing the burden on students.

　　Learn online school "Bian Que system" together.

　　Liu Chang believes that "a tutor who can combine the learning problems in school and open a small stove for students is a good tutor."

　　At the same time, tutors in the Internet age have to understand students’ age psychology, their hobbies, the characteristics of online language and their study habits. If you encounter a special family situation, the tutor even plays a bridge role between parents and students.

　　This "emotional teacher" may politely rush to hand in homework, or he may come to an online "home visit". The things that tutors worry about are very complicated, so parents and students can have a good user experience by doing their best and empathizing.

　　"Self-evolution" of a Class: From Standard Edition to Localization

　　It is hard to imagine that a parent in Baoan District of Shenzhen could not choose a good online class for his children under the dazzling array of online classes.

　　She said with a sad face: "The children said that the knowledge points spoken by the online school teacher are not the same as those spoken by the school teacher. After changing six online schools, her performance has improved to zero, and now she has been blacked out by these institutions. "

　　When choosing online courses, everyone has always taken brand, scale, teachers and price as the selection criteria, but it seems that the localization of courses has never been included.

　　What is a good course? According to Liu Chang, the principal of the online school, the first criterion of a good course is "adapting to local conditions". In other words, a course that is not adapted to local conditions is not a good course.

　　There are differences in the distribution and difficulty of knowledge points in different versions of textbooks, which will eventually be reflected in the examination papers. For students, not choosing localized textbooks is tantamount to taking a detour. If online schools can’t improve their grades quickly, the impact on students’ interest in learning will be enormous.

　　During the epidemic, the online school together created a super curriculum based on the local textbook version, covering the whole grade and the whole subject for primary and secondary school students who postponed their classes all over the country. This curriculum was praised and forwarded by many education experts, media people and teachers.

　　In addition to "adapting to local conditions", a good curriculum design should be "well documented".

　　Professor Chen Enhong of China University of Science and Technology believes that the use of artificial intelligence technology can promote the transformation of learning methods and teaching modes, build a new intelligent education system based on the Internet, and form an online learning and education platform integrating teaching, management and resource construction. To build an online learning education platform based on big data intelligence, it is necessary to build a learner-centered learning environment, develop a deep, intelligent and comprehensive learning analysis system, and provide accurate education and teaching services for teachers, students and administrators, which will help promote the development of personalized learning and lifelong learning, realize the rational and effective use of technology to promote learning and improve the quality of education.

　　With the help of the learning data of more than 100 million users in 160,000 schools in 31 provinces, which have been accumulated in the past 9 years of education and technology, the online school for learning together uses artificial intelligence technology to analyze and excavate, and integrates the difficulties, error-prone points and easy test sites encountered by students all over the country in their studies over the years into the curriculum design to help students complete their learning tasks quickly and efficiently.

　　From "pen tip" to "fingertip", the education system is undergoing an unprecedented change. When online classes are normalized, how to make new technologies better serve education, realize moral education and promote educational equity still has a long way to go.
