Is it difficult to diagnose and treat cough variant asthma? Professor Xie Jiaxing summarized four suggestions.

The original nine Wan Li sorted out the medical respiratory channels included in the collection #2022 world asthma day 5.

* For medical professionals only.

4 suggestions +2 expectations. What does Professor Xie Jiaxing say?

Asthma is one of the most common chronic respiratory diseases in the world. It is estimated that there is one asthma patient in every 20 people in the world, and there are about 20 million asthma patients in China. There is no cure for this disease. Fortunately, proper management and medication can control this disease and enable patients to live a normal and active life.

Therefore, it is very important for clinicians to make standardized diagnosis and treatment of patients to improve the control level of asthma and improve the quality of life of patients. May 3rd, 2022 is the 24th "world asthma day". The Medical Respiratory Channel is fortunate to invite Professor Xie Jiaxing from the Department of Respiratory Medicine of the First Affiliated Hospital of Guangzhou Medical University to teach us about the diagnosis and treatment of cough variant asthma (CVA). Let’s have a look!

Is it asthma or cough?

Please keep these two suggestions about diagnosis!

Professor Xie Jiaxing introduced that CVA is a special type of asthma. Although it has the same pathophysiological mechanism as classic asthma, its clinical manifestations are different. Cough is its only or main clinical manifestation, and there are no obvious symptoms such as wheezing and shortness of breath. Airway hyperresponsiveness is the most important feature of the disease.

The main clinical manifestation is irritating dry cough, which is usually severe. Cough at night and in the early morning is its important feature. Cold, cold air, dust and lampblack are easy to induce or aggravate cough.

As asthma, CVA has a place in chronic cough. Domestic multi-center survey results show that CVA accounts for about one-third of the causes of chronic cough and is one of the most common causes of chronic cough. Therefore, CVA needs to be differentiated from other chronic coughs, such as upper airway cough syndrome (UACS), eosinophilic bronchitis (EB), allergic cough (AC) and so on.

So, how do we diagnose CVA?

At present, the diagnosis of CVA should be based on the comprehensive analysis of symptom-driven, pulmonary function examination and the effectiveness of anti-asthma treatment, and the diagnosis can be made only if the following three conditions are met [1]:

(1) Chronic cough, often accompanied by obvious irritating cough at night.

(2) The bronchial provocation test is positive, or the average diurnal variation rate of PEF is more than 10%, or the bronchial relaxation test is positive.

(3) Anti-asthma treatment is effective.

Considering the current situation of equipment and personnel training in primary hospitals, Professor Xie Jiaxing offered two suggestions:

(1) pay attention to avoid misdiagnosis and missed diagnosis.

In clinical work, Professor Xie Jiaxing met many patients who were diagnosed with CVA in primary hospitals. Many cough patients were diagnosed with CVA only because of a positive bronchial provocation test, so they used many drugs to treat asthma.

But in fact, this condition alone is not enough to diagnose CVA, and we should fully consider it according to our diagnostic criteria. For example, the patient’s symptoms, does the cough last for a long time, often at night? For example, after asthma treatment, is the patient’s symptoms obviously relieved?

In addition, Professor Xie Jiaxing said: "We sometimes see it in clinic, because some grass-roots hospitals can’t carry out bronchial provocation test, and they do bronchodilation test. Perhaps the basic ventilation function of many CVA patients is normal, so it is difficult to make a positive result from the bronchodilation test. At this time, CVA may be missed because of negative results."

(2) Under limited conditions, consider the peak current meter to help check.

Considering that some primary medical institutions do not have the conditions for lung function examination, the peak current meter, as an instrument that can quickly and objectively reflect the peak expiratory flow rate (PEF), can monitor PEF and daily variation rate at any time, and record asthma diaries or draw charts to evaluate and monitor the severity of asthma, and can also find the regularity of asthma attack, which is equivalent to a sphygmomanometer commonly used in hypertension examination or a blood glucose meter commonly used in diabetes examination, and can play a certain role.

Grass-roots doctors can monitor for one week by using the peak current meter. If the PEF changes greatly and exceeds a certain value (for example, the weekly variation rate is more than 20%), it can also prove that patients may have airway hyperresponsiveness, which is helpful for the diagnosis of CVA.

Treatment of CVA, pay attention to patient compliance.

When talking about the treatment of CVA, Professor Xie Jiaxing said that the drugs and principles of CVA are basically the same as those of classic asthma, because they have the same pathophysiological mechanism, and early intervention will help to prevent CVA from developing into classic asthma.

Here are the treatment suggestions listed in the Guide to Diagnosis and Treatment of Cough (2021):

(1) It is recommended that inhaled corticosteroids be combined with bronchodilators, such as long acting beta-agonists (LABA) or inhaled corticosteroids alone (1B). Combined therapy can relieve cough symptoms more quickly and effectively than inhaled corticosteroids or bronchodilators alone, but more clinical research evidence is needed. The treatment time is more than 8 weeks, and some patients may need long-term treatment or intermittent treatment as needed. It is suggested to refer to the asthma treatment mode, evaluate the patient’s treatment response during the treatment and adjust the treatment plan (2D).

(2) If the patient has severe symptoms or airway inflammation, or has poor response to inhaled corticosteroid therapy, oral corticosteroid therapy (10~20mg/d for 3 ~ 5 days) or inhalation preparation of ultrafine particles can be used for a short time. Long-term oral corticosteroid therapy for CVA(2C) is not recommended.

(3) Leukotriene receptor antagonist is effective in treating CVA, which can relieve cough symptoms, improve the quality of life and slow down airway inflammation (2B). Leukotriene receptor antagonist therapy may be effective in a few patients who have failed to respond to inhaled glucocorticoid therapy. The course of treatment and its inhibitory effect on airway inflammation still need further study.

(4) Traditional Chinese medicine believes that CVA is related to wind evil invading the lung and lung qi failing to propagate, so the treatment should be dispersing wind and dispersing lung, relieving cough and relieving sore throat, and Suhuang Zhike Capsule has a certain effect (2B).

If inhaled corticosteroid treatment is ineffective for more than 4 weeks, it needs to be re-evaluated, and attention should be paid to whether there are diagnostic errors, false positive bronchial provocation test or other diseases, or some factors affecting the curative effect.

Therefore, inhaled glucocorticoids are the most commonly used drugs for CVA, but there is a problem of low patient compliance. Here, Professor Xie Jiaxing shared two points to improve patient compliance:

(1) reduce the fear of "hormones"

Many patients will have resistance when they hear the word "hormone". Clinicians can tell patients: "Inhaled glucocorticoids only work locally in our bronchi, and rarely enter the whole body. The side effects are very slight, so we usually don’t have to worry too much."

(2) emphasize not to stop taking drugs by yourself.

This is often the case in clinic. After several days of inhaled corticosteroid treatment, some CVA patients have completely recovered their self-feeling, or they will stop taking the drug on their own after taking the medicine for a period of time with the concept of "three drugs are toxic".

This requires clinicians to make it clear as soon as possible, so that patients can fully realize that this behavior of stopping taking drugs by themselves may lead to repeated illness, and the symptoms may only be relieved after taking drugs for a period of time. For example, "Although the symptoms are suppressed for a short time, chronic inflammation and hyperresponsiveness in the airway still exist, and stopping taking drugs by themselves may easily lead to recurrence or progress from CVA to more serious classic asthma. Therefore, stop taking drugs by yourself, and doctors will use instruments to check related indicators to determine whether you can reduce or stop taking drugs."

In addition, the determination of exhaled nitric oxide (FeNO) as a convenient method for airway inflammation has been popularized in most primary hospitals. If the result is significantly increased, it also suggests the possibility of CVA, and it can also be used to evaluate the patient’s treatment response and adjust the treatment plan.

Expectation and prospect

Professor Xie Jiaxing has been engaged in the diagnosis and treatment of respiratory diseases such as asthma for many years, and put forward two expectations for the diagnosis and treatment of asthma in the future:

(1) New drugs/therapies

At present, inhaled glucocorticoids, as commonly used drugs, need to be used by patients every day, which is prone to low patient compliance and inconvenient compared with other dosage forms such as oral administration. Then, it is expected that more convenient drugs or better alternative therapies will appear in the future, which will be more convenient to use and better control the airway inflammation and airway hyperresponsiveness of CVA, so that diseases can be better treated.

(2) Move towards precision medical care.

Precision medical care is the general direction of modern medical care. We have been carrying out all kinds of cutting-edge research to explore new treatment methods, new technologies and new hopes that are expected to cure various diseases. We also look forward to the development of CVA in this respect, such as clarifying the deep-seated causes of CVA, carrying out individualized radical treatment, completely avoiding CVA from progressing to classic asthma and blocking the disease process.

How damaged is the earthquake in Turkey? This set of satellite images reveals huge ground deformation.

  There were two strong earthquakes in Turkey.

  On February 13th, The Paper (www.thepaper.cn) reporter learned from the Eighth Institute of China Aerospace Science and Technology Corporation that in order to obtain the coseismic deformation field of this earthquake, scientifically grasp the damage degree of the earthquake, and provide important data support for post-earthquake rescue, the Bureau of Science and Technology for National Defense, the National Satellite Remote Sensing Application Center of the Ministry of Natural Resources, and the National Institute of Natural Disaster Prevention and Control of the Ministry of Emergency Management called the Landsat No.1 01 satellite developed by the Eighth Institute. On February 10th, 2023, the post-earthquake synthetic aperture radar (SAR) image was obtained. After differential interference processing with the pre-earthquake SAR image (April 11th, 2022), the coseismic deformation fields of two strong earthquakes were obtained.

  Benefiting from the advantages of L-band radar of Landsat-1 01 satellite, such as long load wavelength and strong penetration of surface vegetation, two SAR images separated by 10 months still maintain high coherence in the coseismic surface deformation area. The InSAR deformation results of Landsat-1 01 accurately describe the damage degree of this earthquake and provide important data support for post-earthquake rescue.

  Co-seismic deformation interferogram of Turkey earthquake in 2023 The pictures in this paper are all from the National Institute of Natural Disaster Prevention and Control.

  From the coseismic deformation interferogram, it can be seen that the interference fringes in the epicenter area are very dense (a single fringe represents that the surface changes by half the radar wavelength along the line of sight, about 11.9cm), which reveals that the two earthquakes have caused huge surface deformation.

  Coseismic deformation field of Turkey earthquake in 2023

  From the image of coseismic deformation field, it can be seen that the maximum dislocation amount caused by two earthquakes is 4-5 meters, and the distribution characteristics of InSAR deformation are consistent with the sinistral movement of faults marked by red lines.

  According to the Eighth Academy, Group 01 of Land Exploration No.1 is a distributed SAR satellite system, which consists of two L-band SAR satellites with the same design parameters. This group of satellites was developed by the Eighth Academy of Sciences. A and B satellites were successfully launched into orbit on January 26, 2022 and February 27, 2022, respectively, and the world’s first L-band double-star constellation for surface deformation interferometry was constructed. The deformation measurement accuracy can reach millimeter level, which can meet the application needs of land resources, earthquakes, disaster prevention and mitigation, basic geographic information acquisition, forestry and so on, and plays an important role in safeguarding national resource security and ensuring people’s life safety.

  At the same time, the Eighth Academy revealed that this group of satellites has been successfully applied to deformation monitoring in typical geological hazard-prone areas such as Datong coal mine in Shanxi and Liupanshui landslide in Guizhou, and also played an important role in demonstration applications such as Luding earthquake in Ganzi Prefecture, Sichuan Province on September 5, 2022.

A move by an American football player caused the vice president to leave angrily.

CCTV News:Earlier, US President Trump and NFL players had a dispute because the players refused to stand up while playing the national anthem. On the 8 th local time, some players knelt down to protest before the game. US Vice President Burns, who was watching the game on the spot, left angrily and expressed his support for Trump.

 

At the NFL game, some players knelt down in the national anthem before the game to express their protest against Trump.

This is the scene of an NFL game in Indiana, USA. In the national anthem before the game, this scene appeared again. The players said that this was done on the one hand to protest against the unfair treatment suffered by blacks, and on the other hand to protest Trump’s position on "kneeling to protest against players".

US Vice President Burns (red circle) who is watching the game on the spot.

US Vice President Burns, who was watching the game on the spot, immediately left with his wife to express his dissatisfaction with these players. He also posted on social media that "I am on the side of President Trump, and I will always stand up for our national flag and national anthem".

 US Vice President Burns posted on social media that he supported Trump.

Subsequently, Trump also issued a document to "like" Burns, and Trump said that he was proud of the decision of the Burns couple.

However, the rugby players who participated in the protest believed that Vice President Burns was making a show.

San Francisco 49ers rugby player Reid:I have great respect for the military national anthem and national flag. Every time I interview, I will say that this is about the systematic racial oppression that has been rampant in the United States for decades. Vice President Burns is confusing the information we want to convey, and I am speechless.

News review

 Black player Kepnik refused to stand up to pay tribute to the national anthem before the game.

 Kepnik took a step back, stopped sitting during the national anthem of other competitions, but did not stand up. Instead, he continued to express his protest by kneeling on one knee.

 Kepnik stopped sitting during the national anthem of other competitions, but did not stand up. Instead, he continued to express his protest by kneeling on one knee.

On August 26th, 2016, Capernacle, a black player of the San Francisco 49ers, refused to stand up and pay tribute to the national anthem before the game to express his dissatisfaction with racial discrimination and police violence in the United States. In September last year, Kepnik got down on one knee before another game and once again expressed his protest. Trump criticized the players for disrespecting the country and even swearing at the players. Trump has been bombarded by people in the sports world, and the "national anthem demonstration" has also intensified.

Heavy metals in well-known rice noodles exceed the standard? Don’t panic, experts have come to interpret it in detail.

Original scientific parenting editorial department Scientific family parenting is included in the topic # Novice parents absolutely need to bring baby cheats! 66

Do you still remember the event # Baby rice noodles with heavy metals exceeding the standard # years ago?

Source: Phoenix Network Video

At that time, many parents were frightened, and there were many messages expressing concern about rice noodles in the background!

Years later, Keke searched several baby rice noodles on the Internet and found that they were still on sale.

So, is this report authoritative and reliable?

Is this rice noodle still edible? How to eat?

If you don’t eat rice noodles, are there other complementary foods to choose from?

How to choose rice noodles?

Today, Keda is going to talk about baby rice noodles.

Image source: scientific family parenting original

one

Can baby rice noodles still be eaten? Listen to the expert’s answer!

The incident of excessive heavy metals in baby rice noodles is related to an investigation report issued by the House of Representatives of the United States Congress.

It is pointed out in the report that the contents of heavy metals such as arsenic, lead, cadmium and mercury in some well-known baby foods on the market reach dangerous levels, which will have adverse effects on the health of infants. In particular, it will damage the development of the brain and nervous system and is irreversible.

However, it was found that the heavy metal content in the investigation report reached a dangerous level, which was only a conclusion compared with drinking water. …

It should be known that in China’s standards, the limit of heavy metals in drinking water is only 0.01mg/L, which is 20 or even 30 times lower than other foods.

Therefore, this comparison is not rigorous! !

Moreover, the heavy metal content of the products mentioned in the report did not exceed the standards set by the US FDA.

Therefore, parents who have eaten this brand for their babies, don’t panic! !

Image source: scientific family parenting original

However, Keke wants to tell you that the ability of rice to absorb heavy metals (arsenic and cadmium) is indeed much stronger than that of ordinary crops!

Our environment (soil, groundwater, irrigation water) has been polluted by heavy metals to some extent, and it is impossible to make rice arsenic-free and cadmium-free. As long as crops grow in the soil, they will absorb these heavy metals.

So, how to eat rice food?

1. Increase the diversity of food and avoid eating only rice noodles.

When the baby starts to eat complementary food, he can choose rice flour fortified with iron grains, such as barley rice flour, oat rice flour and mixed grain rice flour. (The baby is not allergic to food).

In the daily diet, you can also add some coarse grains and miscellaneous beans to reduce the frequency of eating rice.

The department strongly recommends that the proportion of coarse grains should not exceed one-fifth of the staple food, because coarse grains are not easy to digest, and excessive intake may also affect the absorption of minerals.

Image source: scientific family parenting original

Generally, when the baby is 8-10 months old, parents can give the child rotten noodles, gruel, etc. according to the baby’s acceptance, instead of continuously feeding with a single rice noodle.

2. Limit the intake of high-risk foods (such as snacks containing rice ingredients).

Parents should give their children as little as possible snacks made of rice, such as puffs, rice cakes and molar biscuits.

Not only because of the problem of heavy metal content, most snacks like this contain various flavoring agents such as sugar and salt, which easily leads to children’s picky eaters.

3. Try to choose the National Bank version of rice noodles.

In fact, the National Bank Edition means that if foreign brands want to sell in China’s formal channels, they should readjust the ingredients in food until they meet the relevant standards of China.

Therefore, when buying rice noodles or other baby foods, it is best to buy them in formal channels and avoid buying them from private channels. Let the country check for you!

Image source: scientific family parenting original

Finally, Keke would like to emphasize: as long as the content of heavy metals in rice and other foods does not exceed the national standards, we can safely eat them! After all, it is meaningless to talk about toxicity without dose. Unless you eat rice and burst your stomach! (The same is true for baby rice noodles).

So how should parents scientifically choose rice noodles? Keda is coming to teach you how to choose!

2

Choose healthy rice noodles and keep in mind 3 hard standards!

1. See if it contains sugar, salt and essence.

When purchasing rice noodles, parents must carefully read the ingredient list of the products!

If the baby ingests rice flour containing sucrose, it will increase the risk of sweet taste and dental caries.

And containing salt or essence may cause children to be picky eaters. Because babies are very sensitive to taste, they will have a preference for sweet, salty and other tasty foods.

In the end, it is likely that the baby will refuse to accept tasteless food and interfere with breastfeeding and formula feeding.

Image source: scientific family parenting original

2. See if there are any ingredients that are allergic to your baby.

In order to increase the taste of rice noodles and the content of protein, some merchants will add:

Image source: scientific family parenting original

These ingredients are very likely to cause allergic reactions in babies, and they must be discharged after being sensitized, and then eaten routinely.

Secondly, the "nuts" in many compound fruit and vegetable rice noodles are also easy to cause allergies, such as walnuts.

Therefore, when parents buy rice noodles, they must learn to look at the ingredient list to make sure that the ingredients contained are not allergic to children before adding them to prevent anaphylactic shock after eating a lot!

3. See if the iron content is appropriate.

According to the national standard "GB10769-2010 Infant Cereal Supplementary Food", every 100 kilojoules of rice flour should contain 0.25 ~ 0.50 mg of iron.

Therefore, parents should pay attention to the nutrient composition table when choosing, and it is not recommended to buy rice noodles below the national standard range.

Note here that the iron content is not as high as possible, but should be judged according to the baby’s diet!

If the baby is already eating iron-containing food, then you can choose a rice noodle with medium iron content; If the baby only eats breast milk, then you can choose rice flour with high iron content to supplement it.

Image source: scientific family parenting original

If you insist on changing the baby’s rice noodles, it’s not impossible! Because without rice noodles, we have many other choices!

three

Baby’s first bite of complementary food, look for one principle!

For babies aged 4-6 months, breastfeeding can no longer meet the baby’s iron needs, and can only be ingested through complementary food.

Therefore, the baby’s first complementary food lies in "iron supplementation", not in taking some fixed food!

For Xiaobaobo, there are two best choices for iron supplementation:

1. Fortified iron rice noodles

Baby rice noodles on the market are fortified with iron, which can well meet the baby’s demand for iron. Moreover, the sensitization rate of rice is very low, which is not easy to cause baby allergy, and it is nutritious and convenient.

Therefore, baby fortified iron rice flour is the first choice for baby’s first complementary food.

However, Keke does not recommend parents to make rice noodles for their babies!

Because:

① The iron content of rice itself is very low, and it lacks iron-fortified rice flour, which has no supplementary significance for babies.

② Studies show that the arsenic content of homemade rice flour/brown rice flour is even higher than that of ordinary rice flour!

If you really don’t feel comfortable giving your baby rice noodles, then we have other ingredients to choose from:

2. Other ingredients rich in iron

(Note: Be sure to confirm that the baby is not allergic before feeding! )

Image source: scientific family parenting original

If the baby’s iron supplement is not in place, it is likely that the following two situations will occur:

Image source: scientific family parenting original

So how to make iron supplements? Ke has prepared a recipe for iron supplementation for everyone:

Tomato and beef millet porridge:

Ingredients: tomato, beef and millet.

Image source: scientific family parenting original

When feeding the above complementary foods, you must have an allergy test! ! (Be sure to operate under the guidance of the doctor when he thinks it is necessary, and don’t try it at will.)

Image source: scientific family parenting original

If the baby is allergic to these, or is picky about food, it is easier to feed with rice flour.

Finally, in the face of this rumor, Ke greatly wants to tell parents:

1. Baby rice flour is only a stage in the addition of complementary food, and it is usually enough to eat it for 2-4 months.

If the baby is strong enough to accept food and is not allergic, he can even stop using rice flour and switch to iron-supplemented food earlier.

This incident also tells everyone that as long as there is heavy metal pollution in the environment, food is inevitable.

As long as the content of heavy metals does not exceed the national standard, we can eat with confidence! After all, it is meaningless to talk about toxicity without dose.

Finally, increasing the diversity of children’s food is king!

It is better to eat any food in moderation. If the meals at home are always too concentrated on a certain food, then even if the heavy metals do not exceed the standard, other problems will occur!

A balanced and varied diet can make your baby healthier!

Face recognition can’t be brushed? The official responded to the problems encountered when taking the subway!

  

  On April 1st, the first day of commercial operation of Jinan Rail Transit Line 1, many citizens encountered many problems when taking the subway to "try early". On the afternoon of the 2 nd, the relevant person in charge of Jinan Rail Transit Group explained the eight major problems reflected by the public.

  1. Face recognition can’t be brushed? It has been suggested to the public to send clear photos for system optimization.

  "Brush your face" through the security check sounds very "tall", and many citizens have uploaded photo information early, just waiting for "brush your face and try it early" when taking the bus. However, some citizens have encountered the problem that "brushing their faces" cannot be recognized.

  It is understood that the subway ticketing system of Jinan Rail Transit Line 1 is the first in the national subway. For the problem that citizens can’t accurately identify their faces when they brush their faces, the staff analyzed that, first, the system photos were uploaded by users themselves, and the input effect was different; Second, the recognition system is influenced by the environment and brightness; Third, the height and thinness of the citizens and the location of the distance recognizer have an impact on the recognition effect.

  In response to this problem, the relevant person in charge of Jinan Rail Transit Group said that technicians have been instructed to optimize the face recognition modules in a targeted system, and at the same time, the surrounding environment and illumination of each face recognition module are analyzed again. "The face recognition system also has self-learning technology. With the gradual learning and improvement, the recognition speed and accuracy will be improved. At the same time, it is also recommended that the public upload clear photos and try not to upload outdoor photos or backlight photos. "

  2. The bus card can’t be recognized? Some old cards have security vulnerabilities, so it is recommended to replace them with new cards.

  During the operation of Line 1, some citizens who came to the bus with bus cards were stopped in front of the gates because of "invalid cards".

  According to staff statistics, bus cards with problems are divided into two categories. First, activity cards including spring and autumn cards and green travel cards; The second is to issue older cards and bus cards.

  The person in charge of Jinan Rail Transit said that the bus activity card had been notified before and could not be used when taking the subway. The older cards and bus cards were issued earlier because of the long time span and security loopholes. "Including buses, they are gradually replacing old cards with security loopholes. You can replace new cards at bus service outlets for free or apply for Quancheng Pass at subway stations." Among them, Quancheng Tongka can enjoy a 20% discount, but there are no free rides or other preferential activities.

  3. Brush the QR code and allow it in and out? Confusion of multiple payment methods will optimize the APP interface.

  On the first day of the bus ride, some citizens also encountered the problem of brushing the QR code into the station but unable to leave the station.

  According to the person in charge of Jinan Rail Transit, after the statistics of the first day, most of the abnormal users used QR codes to enter and leave the station, which was mainly caused by the mixed QR codes of one-way tickets and stored-value tickets on the APP. "It is possible to brush the QR code of a one-way ticket when entering the station, and turn off the APP during the ride. Because the options of one-way ticket and stored-value ticket are close, the QR code of stored-value ticket was mistakenly selected when leaving the station, resulting in the inability to leave the station without pit stop information. " In this regard, they will optimize the interface when the subsequent version of Jinan Metro APP is updated. "The QR code of the stored value ticket is left on the home page, and the one-way ticket is placed on the secondary interface to strengthen the distinction." Among them, citizens can enjoy a 20% discount by brushing the QR code of stored value tickets, but there is no discount for one-way tickets.

  4. What about the elderly and the disabled? Blind people can enter the station with a disabled card, and guide dogs can also enter the station.

  The person in charge of Jinan Rail Transit said that according to relevant regulations, elderly people aged 60 to 64 can enjoy half-price concessions, and elderly people aged 65 and over can enjoy free rides. "If the old card can’t be brushed, you can arrange to take the green channel. It is recommended to replace the new card in time next time."

  Disabled people who take the subway can enter and leave the station directly through the gate with their love cards, while blind people can enter the station directly with their disability cards and ride for free. Staff will be arranged at the entrance and exit of each station of Jinan Rail Transit Line 1 to help the blind. "Guide dogs can also enter the station". In addition, all stations are equipped with wheelchairs and wheelchair pedals to provide passengers in need.

  5. The subway APP can’t be used? Users are advised to uninstall the ticketing version in time and download the latest version.

  During the trial operation, Jinan Rail Transit launched the "Grab Ticket APP" to provide experience services for citizens who want to "try early". Since March 20, the APP has stopped serving. On the first day of operation on April 1, some unsuspecting users encountered obstacles when using the "grab ticket version APP".

  In this regard, the relevant person in charge of Jinan Rail Transit said that the Jinan Metro APP has been downloaded simultaneously in Android and Apple, and the test version that originally included the ticket-grabbing activities for the visit has stopped serving. "Please ask the public to uninstall the ticket-grabbing version of the APP in time and download and install the latest version in the application market. Jinan Metro APP".

  6. The ticket vending machine can’t buy tickets in cash? Only cash can be bought by the staff.

  The person in charge of Jinan Rail Transit said that with the development of mobile payment technology, the amount of cash tickets purchased is getting less and less. Some cities have gradually cancelled the cash ticket purchasing function of automatic ticket vending machines, and gradually reduced the number of automatic ticket vending machines. At the beginning of the operation of Jinan Rail Transit Line 1, considering that most passengers are used to the convenience brought by mobile payment technology, Jinan Metro encourages passengers to use WeChat or Alipay to purchase tickets at automatic ticket vending machines. For passengers who really only have cash but can’t purchase tickets through WeChat or Alipay, they can pay the cash for the tickets to the on-site staff, and the staff will purchase tickets for the passengers through the ticket vending machine.

  7. How to get an invoice for non-cash ticket purchase? Each station customer service center can receive an APP to provide electronic invoices.

  The relevant person in charge of Jinan Rail Transit said that at present, citizens will provide invoices when purchasing tickets in cash at the customer service centers of all stations across the line. For citizens who use one-way tickets, bus cards and Quancheng Pass cards, they can collect invoices from the station customer service center with valid tickets.

  For citizens who use the QR code and face brushing functions in Jinan Metro APP, they can use the "Electronic Invoice" function in the "Personal Center" interface of Jinan Metro APP to receive electronic invoices according to the prompt process.

Chengdu Rural Commercial Bank bid farewell to Anbang Insurance, and the largest shareholder spent local state capital.


  Since the Anbang incident, Chengdu Rural Commercial Bank Co., Ltd. (hereinafter referred to as "Chengdu Rural Commercial Bank"), the largest shareholder, has been paid close attention to by the market.


  Earlier, it was reported that Chengdu Xingcheng Investment Group (hereinafter referred to as "Xingcheng Investment") would replace Anbang Insurance Group Co., Ltd. (hereinafter referred to as "Anbang Insurance") in Chengdu Rural Commercial Bank, but there was no official response.


  On March 11th, the news was finally verified. In the afternoon, the announcement issued by Chengdu Agricultural Bank in official website showed that Xingcheng Investment intends to accept 3.5 billion shares of the bank held by Anbang Insurance, a shareholder of the bank, accounting for 35% of the shares.


  In a Letter of Commitment for Major Shareholders of Chengdu Rural Commercial Bank Co., Ltd. dated January 9, 2020, Xingcheng Investment also confirmed the above-mentioned equity transfer, but disclosed the specific capital contribution.



  According to the equity transfer project of Chengdu Rural Commercial Bank on December 30, 2019, the price of 3.5 billion shares transferred this time is about 16.5 billion yuan.


  According to official website, Chengdu Rural Commercial Bank, this bank is a joint-stock commercial bank reformed from the former Chengdu Rural Credit Cooperative. It was listed for business on January 15th, 2010, and completed capital increase and share expansion in 2011, with a registered capital of 10 billion yuan. The Bank has 649 institutions at all levels, including 1 business department of the Head Office, 8 branches, 173 sub-branches and 467 branch offices. All 39 zhongcheng village banks initiated in Shandong, Jiangsu, Fujian, Hebei, Sichuan, Yunnan and Xinjiang have been opened.


  According to the audit report of PricewaterhouseCoopers Zhongtian Certified Public Accountants, as of the end of October last year, the bank had total assets of 544.56 billion yuan, total liabilities of 493.978 billion yuan, operating income of 10.6 billion yuan and net profit of 6.285 billion yuan.


  21st century business herald reporter looked up Qixinbao and found that the shares of Chengdu Rural Commercial Bank were scattered. Except Anbang Insurance, only Chengdu Jiaozi Financial Holding Group Co., Ltd. held more than 5% of the shares. After the completion of the equity transfer, Xingcheng Investment will undoubtedly become the largest shareholder of Chengdu Rural Commercial Bank.


  It is worth noting that Xingcheng Investment is 100% owned by Chengdu SASAC and belongs to a state-owned enterprise with strong financial resources.


  According to public information, Xingcheng Investment was established in 2009 with a registered capital of 5.525 billion yuan. By the end of September 2019, the company’s total assets were about 198.2 billion yuan and its net assets were about 81.1 billion yuan.


  Two-year "shrinking table" 160 billion



  On December 30th, Beijing Financial Assets Exchange put up the equity transfer project of Chengdu Rural Commercial Bank. The proposed equity transfer project of Chengdu Rural Commercial Bank is divided into two parts. One is the 3.5 billion shares held by Anbang Insurance Group, and the listing price is about 16.508 billion yuan. Second, Anbang Insurance Group took over about 2.050 billion shares entrusted by Shanghai No.1 Intermediate People’s Court, with a listing price of about 9.669 billion yuan, with a total transfer of about 5.550 billion shares and a transfer price of 26.177 billion yuan.


  Chengdu Rural Commercial Bank was established on December 31, 2009 with a registered capital of 10 billion yuan. According to the special purpose audit report of PricewaterhouseCoopers, at the end of September 2019, the total assets of Chengdu Rural Commercial Bank were about 549.993 billion yuan and the net assets were 43.265 billion yuan; In the third quarter of 2019, Chengdu Rural Commercial Bank had an operating income of 9.076 billion yuan and a net profit of 3.987 billion yuan.


  Based on this calculation, the transfer price per share of Chengdu Rural Commercial Bank is 4.72 yuan, which is about 9% higher than the net capital premium of the bank at the end of September this year.


  Anbang cleared Chengdu Rural Commercial Bank for 16.5 billion yuan, which had been listed once before, but the transferee was delayed. In December 2018, Anbang Insurance Group listed and transferred its 35% stake in Chengdu Rural Commercial Bank at a transfer price of 16.8 billion yuan. According to the net assets of Chengdu Rural Commercial Bank at the end of September 2018 of 4.16 yuan per share, the transfer premium at that time was 1.15 times.


  At that time, an insider of a local bank in Sichuan said that the receiver of Chengdu Rural Commercial Bank may be state-owned assets in Sichuan Province, but the problem of taking over the largest asset of Anbang is the source of funds.


  Chengdu Rural Commercial Bank was once Anbang’s most important financial asset. By the end of 2016, the total assets of Anbang Life Insurance were 1.45 trillion yuan, while the total assets of Chengdu Rural Commercial Bank were 673.149 billion yuan, accounting for 46%.


  Looking back on the history of Anbang’s shareholding in Chengdu Rural Commercial Bank, in December 2009, the CBRC approved the opening of Chengdu Rural Commercial Bank. In September 2011, Anbang Insurance spent 5 billion yuan to acquire 35% of the bank’s equity and obtained a controlling position. The registered capital of Chengdu Rural Commercial Bank increased to 10 billion yuan.


  Judging from the information disclosed in the listing transfer, Chengdu Rural Commercial Bank has been "shrinking its table".


  The bank has not disclosed the financial report after the 2018 annual report. From the end of 2013 to the end of 2017, the total assets of Chengdu Rural Commercial Bank increased significantly from 429.316 billion yuan to 705.562 billion yuan, an increase of 1.64 times in four years. By the end of September 2019, the total assets of Chengdu Rural Commercial Bank had decreased to 549.993 billion yuan. By October, it had dropped to 544.56 billion yuan. That is, in the past two years, the asset scale of Chengdu Rural Commercial Bank has decreased by more than 160 billion yuan.

Ask the world M8 will come! Provide a layout of 5/6 seats, or sell for 350,000 ~ 400,000.

Although there are only three models on sale at present, its M5/M7/M9 models are the top "players". For example, can you imagine a large SUV with a price of more than 470,000, but in May, it obtained the report card of sales data of more than 16,400 new cars? Therefore, with the empowerment of Huawei, the brand of the world can indeed be called a soul, which is exactly what other car companies envy.

No, after the new model, the new model and the customer M9, the customer brand will soon launch a brand-new customer M8 model. The new car is expected to provide a 5/6 seat layout, and the price we guess will start at around 350,000 ~ 400,000. If the price forecast comes true, then there will undoubtedly be opponents in this price range. Let’s take a brief look at it.

Judging from the spy photos exposed, the appearance of the asking world M8 is basically the same as that of the asking world M9. It is also an iconic family-style front face design and a penetrating taillight. The overall visual perception is not much different from that of the asking world M9, but it is slightly smaller than that of the asking world M9 in terms of volume sense, which is also the reason why the positioning of the two models is different.

The picture shows the M9 extended range version (left) and the pure electric version (right).

As for the interior, the M8 is expected to adopt the same interior design as the M9. The center console is composed of a large LCD screen, which looks highly integrated, and the interior should also be equipped with Huawei’s latest HarmonyOS cockpit.

Other configurations, such as rear projection, car refrigerator, 25-speaker HUAWEI SOUND sound system and ADS 3.0 smart driving, should also be available, so I don’t think friends who care about configuration and functionality need to worry too much. This M8 can definitely give it to you.

In terms of power, if there is no accident, the M8 should also provide extended range version and pure electric version for selection. Taking the M9 as a reference, its extended-range model is equipped with a 1.5T turbocharged engine and two front and rear motors, with a total power of 496 HP and a total torque of 675 Nm. The battery CTLC has a pure electric cruising range of 225km and 275km.

The pure electric version of the M9 is more simple and rude. The total power of the dual motors is 530 HP, and the maximum torque is 673 Nm. In terms of battery life, the CLTC of the pure electric version M9 has a pure electric cruising range of 630km and a battery capacity of 100kWh, using batteries from Contemporary Amperex Technology Co., Limited. However, there are only two versions of the pure electric version, and the lowest starting price has reached 509,800, so most users may still buy the extended-range version.

Finally, there is no doubt that the market share of the ideal L8 must be threatened by the arrival of M8. After all, regardless of the price, size, configuration and power form, the M8 seems to be chasing the ideal L8. Therefore, if this new car is really sold at a price of less than 400,000, then the ideal L8 obviously has a strong opponent.

In a word, the brand of Jiejie, which is empowered by Huawei, has already begun to show its edge. With the coming of another new model, Jiejie M8, we also believe that the new car will definitely catch fire after it goes on the market, don’t you believe it? Then let’s wait and see ~ (Text/Youshi Automobile Dazhuo)

Report on the Development Trend of Agriculture and Rural Areas in China in 2023-Accelerating the Construction of an Agricultural Power

China must be strong and agriculture must be strong. The 20th National Congress of the Communist Party of China drew a grand blueprint for promoting the great rejuvenation of the Chinese nation with Chinese modernization, and clearly put forward the great strategic goal of accelerating the construction of an agricultural power. The most arduous and arduous task of building a socialist modern country in an all-round way is still in the countryside. This report reviews the development of China’s agriculture and rural areas in 2022, predicts the development trend in 2023, and points out the key issues that need attention in the future economic and social development of China’s agriculture and rural areas.

Agriculture has progressed steadily, and grain has climbed at a high level.

The year 2022 is a crucial year for the "14th Five-Year Plan" and an important year for China to build a socialist modern country in an all-round way and March into a new journey towards the goal of the second century. China’s economy overcame the multi-point spread of the epidemic and showed a recovery trend in the second half of the year. Agriculture and rural areas continued to develop steadily with high quality, which once again reflected the important role of ballast stones.

The basic position of agriculture and rural areas has been further consolidated. All localities have effectively responded to the epidemic situation and the impact of natural disasters, and the agricultural and rural economy has maintained a good momentum of development as a whole. In 2022, the added value of the primary industry increased by 4.1% over the previous year, reaching 8,834.5 billion yuan, accounting for 7.30% of the GDP of 121,020.7 billion yuan, slightly higher than that in 2021. In the first three quarters of 2022, the total output value of agriculture, forestry, animal husbandry and fishery was 9.8 trillion yuan. Among them, the total output value of agriculture was 5,194.2 billion yuan, the total output value of forestry was 399.15 billion yuan, the total output value of animal husbandry was 2,670.9 billion yuan, and the total output value of fishery was 989.62 billion yuan, which provided a solid support for stabilizing the overall situation of economic and social development.

Grain production continued to climb at a high level, and the goal of stable production and supply was successfully achieved. In 2022, the national grain sown area was 1.775 billion mu, an increase of 10.519 million mu over the previous year, with a year-on-year increase of 0.6%. The total grain output reached 1,373.06 billion Jin, an increase of 7.36 billion Jin over the previous year, and remained stable at more than 1.3 trillion Jin for eight consecutive years. In the face of the global food crisis, China’s grain production has achieved "19 consecutive harvests", and Chinese’s rice bowl has become more secure. The national soybean and oilseed productivity improvement project was launched, and the soybean oilseed expansion has achieved remarkable results, expanding the scale of grain-soybean rotation and promoting the soybean-corn strip compound planting area of more than 15 million mu; The area, yield and total yield of rapeseed harvested in summer have achieved "three increases", and other oil crops such as peanuts and oil sunflower have shown a stable production trend.

In-depth implementation of the strategy of "storing grain on the ground and storing grain in technology" has continuously improved the comprehensive agricultural production capacity. By the end of 2022, 1 billion mu of high-standard farmland will be built nationwide, accounting for more than half of all cultivated land; The seed industry revitalization campaign started well, and a world-class national crop and marine fishery biological germplasm resource bank has been built; Stabilize grain, expand oil, improve quality and efficiency, optimize and adjust national seed production counties and regional breeding bases, and increase the seed supply guarantee rate from 70% to 75%; The level of agricultural mechanization has improved steadily, and the mechanization rate of crop cultivation and harvest has exceeded 72%, of which the comprehensive mechanization rate of wheat cultivation and harvest has reached over 97%, basically realizing the whole mechanization. The mechanization level of animal husbandry, aquatic products and facility agriculture has improved significantly; The agricultural technology system and agricultural technology extension system were further improved, and the contribution rate of agricultural science and technology progress exceeded 62%.

The price fluctuation of agricultural products is widely concerned. In the four quarters of 2022, the producer price index of agricultural products (the same period of last year =100) was 93.3, 99.3, 108.2 and 105.7 respectively. Among them, the price of livestock products fluctuated the most, and the producer price index was 74.7, 88.3, 115.4 and 125.2 respectively. Pork prices showed a trend of first falling and then rising. From January to March, 2022, the ex-factory price of lean-skinned pigs dropped from 18.95 yuan to 15.73 yuan per kilogram. After March, the price of pork continued to rise, reaching a peak of 34.41 yuan per kilogram in October and falling back to 24.79 yuan in December.

The price of important agricultural materials is rising obviously. The price of corn is at a historical high, and the prices of other major raw materials are higher than the same period in 2021, which has promoted the year-on-year increase in the ex-factory prices of compound feed and concentrated feed products. The price of soybean meal continues to rise. Since February 2022, the opening price of soybean meal futures has exceeded 4,000 yuan/ton. In the first three quarters, the prices of chemical fertilizers such as potassium chloride, urea and diammonium phosphate generally showed an upward trend. In September 2022, the prices of domestic potassium chloride, domestic diammonium phosphate and domestic urea were 3,954.8 yuan, 3,776.16 yuan and 2,745.71 yuan per ton, respectively, which were 28.32%, 17.74% and 20.52% higher than those in January. In November, it dropped to 3604.30 yuan, 3589.30 yuan and 2695.15 yuan per ton respectively.

Agricultural products trade keeps the pattern of "big import and small export"

Affected by the global extreme weather and the conflict between Russia and Ukraine, the world agricultural products market volatility intensified in 2022. The food price monitoring data of the Food and Agriculture Organization of the United Nations (FAO) shows that the international food demand continues to be firm, but the food supply decreases, and the prices of all kinds of food in the international market remain high.

In 2022, the import and export amount of agricultural products in China reached US$ 334.32 billion, a year-on-year increase of 9.9%. Among them, the import value was US$ 236.06 billion, up 7.4% year-on-year; The export value was US$ 98.26 billion, up 16.5% year-on-year. The export was mainly concentrated in labor-intensive agricultural products such as aquatic products, vegetables, melons and fruits and tea. The trade deficit of agricultural products reached US$ 137.8 billion, slightly larger than that in 2021. Generally speaking, China’s agricultural products trade still presents a pattern of "big import and small export", supplemented by the international market, which meets the domestic demand for agricultural products.

The import quantity of different varieties of grain mostly shows a downward trend compared with the same period in 2021. In 2022, except for the significant increase in rice imports, wheat imports increased slightly, and corn and soybean imports decreased. Among them, corn imports were 20.62 million tons, down 27.3% year-on-year. Soybean imports were 91.08 million tons, down 5.6% year-on-year. However, due to the rising international soybean prices, China’s soybean imports still increased by 14.4% compared with the same period in 2021, reaching 61.24 billion US dollars. China’s soybean imports mainly come from Brazil and the United States, with Brazil accounting for about 2/3 and the United States accounting for about 30%.

Green development of agriculture has reached a new level.

The green development of agriculture has achieved remarkable results.

First, the supply capacity of high-quality agricultural products has been continuously enhanced. According to the data of the Ministry of Agriculture and Rural Affairs, in 2022, the pass rate of routine monitoring of quality and safety of agricultural products in China exceeded 97.6%, and the number of green, organic and geographical indication agricultural products totaled more than 63,000, and the brand effect of agricultural green food continued to expand.

Second, the environmental protection effect of agricultural producing areas is remarkable. The improvement of comprehensive utilization rate of crop straw, agricultural film recycling rate and comprehensive utilization rate of livestock manure effectively promoted the governance of agricultural industrial environment, reaching 88%, 80% and 78% respectively. By the second quarter of 2022, the effective coefficient of farmland irrigation water in China has increased to 0.57. According to statistics, in 2021, the national fertilizer application amount was 51.91 million tons (in pure terms), which was 13.8% less than that in 2015, and the fertilizer application amount kept decreasing for six consecutive years, and the fertilization structure was optimized. The consumption of pesticides in China was 248,000 tons (100% off), which was 16.8% lower than that in 2015, and kept negative growth for six consecutive years. At the same time, low-toxic and slightly toxic pesticides accounted for 85%. The coverage rate of green prevention and control of major crop pests and diseases in China is 46%; The safe utilization rate of polluted farmland exceeds 90%.

Digitalization helps increase agricultural efficiency and farmers’ income.

Remarkable progress has been made in the construction of digital villages, and the digital gap between urban and rural areas has been further narrowed. Internet infrastructure in rural areas has been comprehensively improved. According to the report of China Internet Network Information Center, as of June 2022, the Internet penetration rate in rural areas reached 58.8%, up 1.2% from December 2021. According to the statistics of the Ministry of Industry and Information Technology, more than 800,000 5G base stations will be opened in 2022, realizing "broadband access to every village" and "5G access to counties" nationwide.

E-commerce of agricultural products has developed vigorously, and online retail of agricultural products has increased significantly. In 2022, the national rural online retail sales reached 2.17 trillion yuan, a year-on-year increase of 3.6%. The online retail sales of agricultural products nationwide reached 531.38 billion yuan, up 9.2% year-on-year, and the growth rate was 7.3 percentage points higher than that in 2021. Rural e-commerce has become an important means to help rural revitalization and consolidate and expand the achievements of poverty alleviation.

In recent years, the overall development level of county digital inclusive finance in China has been continuously improved, which has injected new kinetic energy into rural revitalization. Emerging modes such as land transfer, agricultural materials e-commerce, online platform for agricultural machinery services and online agricultural technology services have also promoted the further application of digital information and technology in the circulation of agricultural production factors.

The per capita disposable income of rural residents continues to grow faster than that of urban residents. In 2022, the per capita disposable income of rural residents was 20,133 yuan, up 6.3% year-on-year. After deducting the price factor, the real growth rate was 4.2%, which was 1.2 percentage points higher than the economic growth rate, and the nominal growth rate and real growth rate were 2.4 and 2.3 percentage points faster than those of urban residents respectively.

From the perspective of income composition, all four types of income have increased throughout the year. Among them, the wage income is 8449 yuan, accounting for about 42.0% of the per capita disposable income of rural residents; The net operating income is 6972 yuan, accounting for about 34.6%; The net transfer income is 4203 yuan, accounting for about 20.9%; The net income of property is 509 yuan, accounting for about 2.5%.

With the continuous improvement of rural logistics system and commercial facilities, rural residents’ consumption expenditure has overcome the impact of the epidemic and gradually recovered in fluctuations. In 2022, the per capita consumption expenditure of rural residents was 16,632 yuan, a real increase of 2.5% after deducting the price factor. The per capita consumption expenditure of rural residents is 2.7 percentage points higher than that of national residents and 4.2 percentage points higher than that of urban residents.

The Central Rural Work Conference emphasized that consolidating and expanding the achievements of poverty alleviation is the bottom line task of comprehensively promoting rural revitalization. Whether this task can be promoted smoothly depends on the industrial development in poverty-stricken areas and the employment situation of poverty-stricken people.

In 2022, the subsidy funds for rural revitalization by the central government increased by 5.4% over the previous year, reaching 165 billion yuan, of which more than 55% was used for industrial development. All 832 poverty-stricken counties in China have cultivated leading industries in combination with their own resource conditions. In order to ensure the employment of the people out of poverty and increase their income, relevant local departments have strengthened employment training and developed public welfare posts, and achieved good results. More than 65.7% of the monitored objects have eliminated the risk of returning to poverty. The number of migrant workers out of poverty nationwide reached 32.78 million, exceeding the annual target and task. In November 2022, the General Offices of the General Office of the Central Committee of the CPC and the State Council issued the Measures for the Implementation of the Responsibility System for Rural Revitalization, which further clarified the responsibilities of departments at all levels and consolidated the institutional foundation for rural revitalization.

Modernization transformation has entered a critical stage.

At present, China’s agricultural and rural areas have entered a critical stage of modernization, and the future development of agricultural and rural areas should focus on the following links.

First, profoundly grasp and practice the concept of big food. The central rural work conference pointed out that it is necessary to establish a big food concept, build a diversified food supply system and develop food sources in multiple ways. With the improvement of living standards and agricultural production efficiency, the food consumption structure of residents has changed significantly, and the single diet structure has become a thing of the past, and the food sources are more diverse and abundant. This requires the effective supply of meat, fruits and vegetables, dairy products, aquatic products and other foods to meet people’s nutritional and health needs while ensuring food supply. All-round and multi-channel development of food resources is not the uncontrolled development of natural resources such as cultivated land, grassland, forest and ocean, but the efficient use of resources under the framework of ecological civilization construction, with more emphasis on resource conservation and ecological protection. To practice the concept of big food, it is necessary to constantly improve the agricultural production and management system and mechanism with the rural land system as the core, and adopt environment-friendly agricultural production and processing technology to achieve the balance between material demand and natural resources.

The second is to accelerate the reshaping of urban-rural relations. Influenced by traditional industrialization, China’s urban-rural dual structure has not been completely broken, which restricts the process of economic and social modernization. The income gap between urban and rural areas is the most direct manifestation. Although the income ratio between urban and rural areas is decreasing, the ratio of urban and rural per capita disposable income is 2.45∶1 in 2022, but the absolute value of the per capita disposable income gap between urban and rural residents still reaches 29,150 yuan. Report to the 20th CPC National Congress, the Communist Party of China, put forward that priority should be given to the development of agriculture and rural areas, and the integration of urban and rural areas should be adhered to, so as to smooth the flow of urban and rural factors. Urban prosperity and rural prosperity cannot be separated. In essence, the rural revitalization strategy is to rationalize the relationship between workers and peasants and the relationship between urban and rural areas from a strategic perspective. To completely break the dual structure of urban and rural areas means changing the one-way flow pattern of resources from agriculture and rural areas to cities and industries, and realizing the two-way flow of urban and rural labor, capital, technology and data. In the future, we should focus on county development and comprehensively promote the integrated development of urban and rural areas. On the one hand, it is necessary to upgrade the infrastructure and basic public services in rural areas within the county scope to enhance the rural value; On the other hand, it is necessary to optimize the layout of county space and industrial planning, accelerate the two-way flow of factors, and realize that agriculture is supplemented by industry, rural areas are led by cities, and agricultural and rural areas are promoted to prosperity by urban radiation.

Third, give full play to the important role of rural collective economy in agricultural and rural modernization. Developing a new rural collective economy is one of the core tasks of building an agricultural power. At present, the new rural collective economy has formed various forms of development, and its business activities include resource contracting, property leasing, intermediary services, resource use rights, and rural construction projects with financial input. All localities are still exploring the integration of multi-village resources by strong village companies to encourage the development of the group. With the deepening of agricultural modernization, the business activities of collective economic organizations extend to the fields of scale operation and agricultural socialized service. Generally speaking, the new rural collective economy has shown great vitality, and its role in rural economic development, industrial prosperity and farmers’ income increase has become more and more obvious. To speed up the process of agricultural and rural modernization, we need to give full play to the important role of rural collective economy. As one of the forms of public ownership, the collective economy is an important part of the market economy in Socialism with Chinese characteristics. Adhere to the advantages of the combination of unification and separation of rural management system, give play to the function of "unification" of rural collective economy, and lay a solid foundation for common prosperity.

The growth trend will remain unchanged in 2023.

Combined with the employment population of various industries, social fixed capital investment and employment of migrant workers from 2011 to 2021, a forecasting model is established according to the input-output structure of 135 departments in China. Considering the domestic and international development situation, the report results are simply averaged by setting different simulation schemes with the model, and the development trend of agriculture and rural areas in 2023 is predicted as follows.

The economy continued to maintain its growth trend, and agriculture boosted GDP growth by 0.73 percentage points. The forecast results show that the agricultural added value continues to grow, and it is estimated that the growth rate of agricultural added value will be 9.8% in 2023, which is higher than the growth rate of GDP; The proportion of agricultural added value has increased, reaching about 8%, slightly higher than that in 2022; The added value of processing industries (grain grinding products, feed processed products, vegetable oil processed products, sugar materials and sugar products, meat processed products, aquatic products processed products, vegetables and fruits processed products, dairy products and tea) with main agricultural products as raw materials will continue to grow, with a growth rate of 2.0%, accounting for 1.7% of GDP. It is estimated that the trade volume of agricultural products will reach US$ 387.45 billion in 2023, up by 15.9% year-on-year, of which the export volume of agricultural products will be US$ 110 billion, up by 11.9% year-on-year; The import value of agricultural products was $277.45 billion; The trade deficit of agricultural products was US$ 1,674.5, up by 21.5% year-on-year; Imports of edible oil seeds, edible vegetable oils and livestock products will account for more than 60% of domestic agricultural products imports, and the proportion of aquatic products imports is expected to further increase.

Per capita disposable income in urban and rural areas continues to increase. It is estimated that in 2023, per capita disposable income will exceed 41,000 yuan, up 11.2% year-on-year, including 53,100 yuan for urban residents and 22,400 yuan for rural per capita disposable income, up 7.7% and 11.3% respectively. In 2023, the per capita consumption expenditure of residents will maintain a growth trend, and it is estimated that the per capita consumption expenditure of residents will be 26,700 yuan, an increase of 8.8% year-on-year; The average consumption expenditure of urban residents and rural residents was 33,000 yuan and 17,200 yuan respectively, up by 8.6% and 3.4% year-on-year; Judging from the categories of residents’ consumption expenditure, the per capita service consumption expenditure and medical care expenditure of residents both increased at a rate of more than 15% year-on-year.

To sum up, China’s agricultural economy has strong resilience, great potential and sufficient vitality, and its long-term positive fundamentals remain unchanged.

Take various measures and comprehensively promote rural revitalization

To promote rural revitalization in an all-round way and accelerate the construction of an agricultural power, it is necessary to unswervingly guarantee the priority development of agriculture and rural areas with the ambition of "Yu Gong Yi Shan" and the perseverance of dripping water wears away stones.

Firmly promote farmland construction and seed industry revitalization to ensure food security. Ensuring food security is a necessary condition for building a strong agricultural country, and we should continue to thoroughly implement the strategy of "storing grain on the ground and storing grain in technology". While ensuring the number of high-standard farmland construction, we will further promote the transformation and upgrading of high-standard farmland. Update and transform farmland infrastructure, explore high-standard farmland management and protection mode, prevent soil fertility from declining, and ensure that "grain field" is "fertile field". Strengthen the monitoring and investigation of cultivated land quality, promote conservation tillage, promote the recuperation of cultivated land, and strive to improve the quality of cultivated land. To promote the revitalization of seed industry, on the one hand, we should continue to accurately identify and protect germplasm resources and improve the resource database of important seed products; On the other hand, we should continue to focus on the breeding of improved varieties, effectively guarantee the supply of improved varieties, and comprehensively improve the level of improved varieties. In terms of technological innovation, efforts should be made to tackle the key problems of "sticking the neck" technology, strive to make breakthroughs in cutting-edge technology fields, increase the protection of original breeding innovations, and promote the transformation of China from a big seed industry country to a strong seed industry country.

Continue to optimize the trade structure and ensure the supply of agricultural products. Improve the strategic layout of agricultural products trade, broaden trade channels and give play to the important role of regional markets. Deepen the economic and trade relations of agricultural products with the countries and regions of the regional comprehensive economic partnership agreement and the "Belt and Road Initiative", build the whole trade chain including warehousing, logistics and transportation, and continuously expand the trade space of agricultural products. On the import side, it is necessary to broaden the import channels and promote the diversification of the import market of agricultural products, so as to spread risks, avoid the break of supply chain and ensure the supply of important agricultural products. In terms of export, it is necessary to cultivate the international competitive advantage of agricultural products and improve the terms of trade of agricultural products. By promoting the scale and standardization of production, the quality of agricultural products will be continuously improved. We should adhere to the market demand-oriented, provide public services to support enterprises to build agricultural products brands and carry out international marketing, promote the export of superior agricultural products based on quality and guided by brands, constantly explore the international market, expand value-added space, and enhance the market influence of China’s agriculture in global competition.

Based on the high-quality development of agriculture, vigorously promote agricultural socialization services. Practice has proved that agricultural socialized service can promote the use of advanced agricultural green technology by expanding production scale and standardizing operations. To promote the high-quality development of agriculture, it is necessary to improve the socialized service system of agriculture and effectively realize the organic connection between small farmers and modern agriculture. To give full play to the role of agricultural socialized service in agricultural production, first, we should further strengthen the level of agricultural basic service, and provide more advanced and diversified service modes for agriculture by increasing the scientific and technological content of agricultural investment, improving farmers’ professional quality and building agricultural basic service stations. Second, we should improve the quality of agricultural socialized services, enhance the enthusiasm of farmers to participate in socialized services, so that the majority of farmers can participate in the agricultural production process and ensure agricultural production efficiency. Third, we should continue to strengthen financial investment in rural areas. Agricultural socialization service aims to provide efficient services for farmers in the production process. In order to ensure the quality of agricultural socialized service, we should provide sufficient financial support to ensure the healthy development of agricultural socialized service system.

Increase investment in digital rural construction and improve the commodity service network system. Digital village is an important breakthrough to comprehensively promote the rural revitalization strategy, and it is also an important content of building a digital China. Therefore, first, we should increase investment in digital rural construction and improve rural information infrastructure. To ensure the priority development of agriculture and rural areas, it is necessary to increase investment in infrastructure, and information infrastructure is an important content. It is urgent to fill the shortcomings of rural information infrastructure, establish and improve the rural information service system, and accelerate the narrowing of the digital divide between urban and rural areas. At the same time, we will strengthen the education and training of farmers’ Internet ability, promote online transactions such as digital inclusive finance and land transfer, and expand the application scenarios of digital technology in agriculture and rural areas. Second, we should build an efficient modern commodity service network system. Build a rural logistics information platform, improve the county and rural three-level logistics system with the Internet and information technology as the core, promote the informationization and visualization of the whole process system of the supply chain, reduce the distribution loss and cost, reduce the transaction cost generated by the circulation link, and avoid the efficiency loss of factor allocation and product circulation.

Promote non-agricultural employment and return to their hometowns to start businesses, and ensure sustained and steady income growth. Smooth flow of urban and rural factors is an important condition to realize rural revitalization. On the one hand, we should continue to steadily promote the non-agricultural employment of rural labor force, increase the skills training for farmers, especially those who are out of poverty, strengthen employment guidance services, and promote the non-agricultural employment of rural labor force. On the other hand, we should create conditions to promote returning home to start businesses and reverse the one-way flow of factors between urban and rural areas. At present, there are more than 10 million entrepreneurs returning to their hometowns in China. By attracting entrepreneurial talents, strengthening entrepreneurial services, building entrepreneurial parks, and providing preferential land and tax support, we will promote returning home to start businesses. In addition to ensuring the growth of net operating income and wage income, it is also necessary to promote the growth of net property income and net transfer income of rural residents. It is necessary to improve the net income level of rural residents’ property, implement various subsidy policies in agriculture and rural areas, and ensure the sustained and steady growth of income.

Continue to deepen rural reform and develop and strengthen the rural collective economy. To realize the goal of agricultural and rural modernization and common prosperity, it is necessary to further deepen rural reform and develop and strengthen rural collective economy. First, continue to deepen rural reform. Improve the rural management system, innovate the agricultural management system and mechanism, and promote the reform of rural collective property rights system, unify the strengthening of the foundation of collective ownership, safeguarding and realizing the rights of farmers’ collective members with activating resource elements, do a good job in the separation of rights and powers of rural collective resource assets, and let farmers share more achievements in the reform. The second is to improve the management ability of rural collective economic organizations and expand the rural collective economy. Increase financial support, multi-sectoral joint efforts to implement tax incentives for rural collective economic activities. On the one hand, the value-added tax and income tax involved in the transfer and change of rural collective assets, as well as the taxes and fees in the operation process of rural collective economic organizations, and the tax deduction policy for public welfare, welfare expenditure and social security expenditure borne by rural collective economic organizations is implemented to ensure that rural collective economic organizations go into battle lightly. On the other hand, we should increase innovative financial support policies and improve the financing capacity of rural collective economic organizations.

Is it unsafe for banks to brush their faces to withdraw money? Experience: if you think too much, you don’t spit money directly.

  Zhongxin. com, Beijing, November 23rd (Wang Jiayu, Li Jinlei) Brush your face is going deep into the lives of Chinese people. Recently, many domestic banks have launched the ATM machine "face-brushing withdrawal" function. So, what is the "face-brushing withdrawal"? What about its security? Zhongxin. com conducted a field visit.

  Experience — — You can withdraw money in half a minute.

  Zhongxin. com noted that recently, a number of banks, including China Merchants Bank and Agricultural Bank, announced the launch of ATM machines’ "face-brushing withdrawal" function in some cities and outlets, which attracted attention.

  So, how should "brush face to withdraw money" operate? What kind of experience? Zhongxin. com came to the business outlet of a bank in Beijing. At present, the outlet has been equipped with an ATM machine with the function of "brushing face to withdraw money".

  Click the "brush face to withdraw money" button on the ATM machine, and enter the face recognition interface, prompting the cashier to look straight at the camera, exposing his forehead, bareheaded, and keeping a distance of 50CM from the camera.

  Zhongxin. com found that face recognition is very fast, only 1-2 seconds. After the face is brushed, the cashier is required to enter the ID number or mobile phone number, and finally enter the withdrawal password to enter the account selection page. After selecting an account, you can withdraw money, and the whole process can be completed in about half a minute.

  So can you brush your face successfully when the cashier wears a hat and sunglasses? When the cashier tried to wear a hat and sunglasses one after another, it was unrecognizable when brushing his face.

  Do you need to open it separately? Is there a limit?

  Regarding whether the face-brushing withdrawal function needs to be opened separately, the customer service staff of Agricultural Bank told Zhongxin.com that "face-brushing withdrawal" does not need to be opened; The customer service staff of China Merchants Bank said that this function needs to be opened. The process is to log in to the mobile banking, click "My"-"All", and click "ATM Brush Face Withdrawal" in the "Assistant" to open it.

  In addition, there is a quota limit for "face-brushing withdrawal". China Merchants Bank’s cumulative withdrawal limit for a single card on the same day is 3,000 yuan; Agricultural Bank of China does not exceed 3,000 yuan per day for a single transaction, 10,000 yuan per day in total, and no more than 5 times per day.

  Investigation — — What do people think of "brushing face to withdraw money"?

  So, what is the public’s attitude towards this convenient function of withdrawing money without inserting a bank card?

  When Ms. Wang, a white-collar worker, first heard about this function, she expressed her concern to Zhongxin. com: "This thing is very dangerous. If you are kidnapped, just take it directly and brush your face without forcing you to say your password."

  Others are not clear about the process of "brushing face to withdraw money", thinking that bank cards still need to be inserted. Some people, like Ms. Wang, mistakenly think that they can withdraw money by brushing their faces without entering other information.

  After the field experience, we can find that, in fact, you don’t need to insert a bank card to withdraw money, but after face recognition, you still need to enter your personal identification information and withdrawal password before you can withdraw money. It’s not what you think, you can withdraw money simply by brushing your face.

  Discussion — — Is it safe to "brush your face to withdraw money"?

  Qiu Xuekan, a visual analysis expert of 360 Artificial Intelligence Research Institute, told Zhongxin.com that "face-brushing withdrawal" uses face comparison technology, that is, whether the face in front of the ATM and the face registered by the user ID card in the system are the same person, before comparison, it is necessary to ensure that the face in front of the camera is real and effective, that is, live detection.

  Regarding whether "face-brushing withdrawal" is safe, the relevant bank told the media that the technology is safe, and it can completely resist photos, face-changing videos, remakes and mask attacks, with high recognition accuracy.

  However, many people are still worried that technologies such as 3D masks may still break through this technology. Qiu Xuekan emphasized that "brush face to withdraw money" does not mean that you can withdraw money by brushing your face, but you can first brush your face and enter your mobile phone number for identity comparison, and then enter your password to withdraw money. Therefore, the role of face brushing is to replace the physical bank card, and the security of withdrawal is still mainly guaranteed by password, and the key is to ensure that the withdrawal password is not leaked.

  Huang Di, an associate professor at Beihang University, said that every technology can’t be perfect, and high-tech technologies have both "attack" and "defense". For any science and technology, attacks with various intentions always exist. After the system is threatened, some emergency plans will be put forward according to the attacks. "Attack" and "defense" can be said to be progressing together.
