　　[Great motherland, unforgettable songs].

　　"Splendid rivers and mountains are picturesque, and the motherland is building a cross-horse. It’s a great honor for me to be an oil worker and travel around the world wearing an aluminum helmet … …” This heroic ode to oil workers is not only a clarion call to encourage oil workers from generation to generation to join in the construction of the motherland, but also an overall portrayal of the outstanding heroes of the working class in China. Although it was written more than half a century ago, it is still so exciting and exciting to sing today.

　　The composer Qin Yongcheng (1933— 2015) is the first generation composer trained in New China. During more than half a century’s creative career, he has created a large number of musical works with high artistic achievements and wide social influence, such as the song "I offer oil for the motherland", "Chairman Mao travels all over the motherland", My People，My Country, vocal concerto "Haiyan", symphonic poem "Two Little Cowboys" and movie music "Entrepreneurship" and "Marshal and Soldiers". He made great contributions to the music, art and education in our country all his life.

　　Three days with the "Iron Man"

　　In 1964, a notice brought Qin Yongcheng into close contact with Li Jiefu, a famous composer and president of Shenyang Conservatory of Music. It was this notice that made him have an indissoluble bond with oil workers all his life. In March this year, China Musicians Association organized some composers to experience life in Daqing Oilfield and created a batch of works reflecting oil workers. Dean Hijacking also received a notice, asking him to report to Sarthou, Heilongjiang Province on March 20th. After receiving the notice, the dean of the robbery immediately made preparations for leaving. Due to physical reasons, the college is going to find a young man to accompany the dean of the robbery to "go north". At the suggestion of the dean of the robbery, Qin Yongcheng will accompany him. Unfortunately, Qin Yongcheng was suffering from a high fever and had been in bed for three days. Upon hearing this, Dean Hijacking personally visited Qin Yongcheng’s home and told him to rest at ease for illness. In the face of this rare opportunity, Qin Yongcheng looked forward to his early recovery. Although his fever had gone down the next day, he was still very weak, and insisted on accompanying Dean Jiefu.

　　On the evening of 19th, Qin Yongcheng got his wish and boarded the train to the north. In the car, Qin Yongcheng finally put forward the question that was hidden in his heart: "Where are we going to Sarthou?" Dean Hijacking told him quietly: "Sarthou is a big oil field, called Daqing Oilfield, and it is still confidential." After moving to Daqing, Qin Yongcheng lived with many famous musicians such as Lv Ji, Qu Wei, Wang Xin, Zhang Lu and Jiefu in the guest house of Daqing Petroleum Command.

　　Since the next day, the oil field has arranged courses for musicians to introduce oil-related knowledge, from exploration and drilling to oil production and refining for ten days, with one content per day. Ten days later, the oilfield arranged for them to experience life in the first line. Qin Yongcheng, Jiefu and Wang Xin (songwriters of "Singing the Motherland") were assigned to the "1205 Hero Drilling Team" with Wang Jinxi, the "Iron Man", and lived together with the "Iron Man" for three days. During this period, Wang Jinxi told Qin Yongcheng that when he held a People’s Congress in Beijing in 1959, he saw that the buses in Beijing were in a heavy mood because of lack of oil and carrying gas bags. He also listened to him tell the story of the Daqing Petroleum Congress. In the spring of 1960, Wang Jinxi’s drilling team was in Yumen Oilfield. When it was heard that a large oil field had been discovered in the north, the whole country was going to hold a general meeting there, and immediately asked the superior to fight. They said goodbye to their relatives and boarded the train going north in their light clothes. Faced with the harsh climate, hard living and working environment, and poor equipment, oil workers shouted the loud slogan of "if you have the conditions, you should go if you don’t have the conditions" in order to get rid of the label of "poor oil" as soon as possible and break the economic blockade of western hostile forces. "When the oil workers roar, the earth will shake three times."Qin Yongcheng’s soul was strongly shocked and greatly impacted by his earth-shattering fearless revolutionary heroism. Especially in the days spent with Wang Jinxi and his heroic drilling crew, Qin Yongcheng’s understanding of oil workers has been greatly sublimated, and he has a strong emotional resonance. He is determined to create works that can reflect the spirit of oil workers to express his high respect for them.

　　A masterpiece completed in the canteen of the hostel.

　　After three days of experience, Qin Yongcheng returned to the guest house, and the Propaganda Department of the Party Committee of the Oilfield prepared a batch of lyrics reflecting the work and life of Daqing Oilfield and oil workers for them, hoping that composers would compose music for them. After the old composers had chosen the lyrics, Qin Yongcheng also chose them. At this time, a lyric jumped into his eyes, which was written by oil worker Xue Zhuguo, "I offer oil for my motherland." This first-person lyric is vivid and vivid, which vividly depicts the heroic and optimistic mood of oil workers and the fearless revolutionary spirit of fighting against the world. The more Qin Yongcheng watched it, the more he liked it. The more he watched it, the more excited he became. At this moment, he was inspired and full of thoughts. In the canteen of the hostel, he finished writing this work in just 20 minutes.

　　Inspired by the artistic conception of the lyrics, the prelude of the song adopts a fast speed, a lively and elastic rhythm, and a fluctuating melody line, like a train full of oil workers galloping in the splendid rivers and mountains of the motherland, from the northwest of the motherland to the northeast thousands of miles away. Then, the heroic song of the oil workers was introduced: "The beautiful rivers and mountains are picturesque, and the motherland is building a beautiful horse. I am honored to be an oil worker and wear an aluminum helmet to travel all over the world." The melody of the song is broad, fresh and smooth, which vividly depicts the bold spirit of oil workers and the revolutionary optimism full of pride and self-confidence. On the word "kua" of "kua steed", the melody absorbs the elements of rap music and adopts a sliding tone, which is not only in line with the rhyme of Chinese four tones but also forceful, and can better highlight the bold and hearty character of oil workers. These four sentences are lyrical paragraphs, which vividly depict the heroic fighting spirit and optimistic spirit of oil workers moving to the north and south and being at home all over the world.

　　In order to show the dauntless heroism spirit and heroic spirit of oil workers, who are "fearless of heaven, fearless of earth, and fearless of storm, thunder and lightning", Qin Yongcheng treated these two lyrics into short and powerful eight-point dotted notes and syncopated rhythm, which made the music more powerful and dynamic. At the same time, it not only forms a sharp contrast with the previous lyric paragraphs, but also lays a good foundation for the climax of the whole song that appears later.

　　The climax of the song is in the last two phrases, "I contribute oil to my motherland, where there is oil, my home is there". In order to make the climax of the song more prominent and infectious, Qin Yongcheng ingeniously treated the first beat at the beginning of this sentence as a rest, and started the word "I am" from the weak beat to highlight the word "ancestor" in the next section. Then, on the word "oil" for "offering oil", the melody adopts a circuitous upward movement, forming a large-span 10-degree interval in the range. In the last four bars of the song, Qin Yongcheng skillfully used the drawl of China’s traditional opera music for reference. It is worth mentioning that in the first draft of the work, the last four sections are not like this, but after Qin Yongcheng returned to school, he sang the work to friends and students, listened to and adopted everyone’s suggestions, and changed the original last simple melody into the current one-stop drawl. In this way, the music is more infectious and dynamic, which not only depicts the free and easy character of oil workers, but also makes the whole song end in an atmosphere full of optimism and pride. The revised work was published in the journal "Music Life" of Liaoning Branch of China Music Association, which soon became a hero’s ode to oil workers in the north and south of the motherland and inside and outside the Great Wall.

　　The only "composer of oil workers"

　　The first singer of this song, Liu Bingyi, a famous baritone singer of the former Central Orchestra, also played an important role in the promotion of this song. He and Qin Yongcheng also became attached to this song, and it was sung for 50 years. And Qin Yongcheng also started from this song, and successively created a number of excellent works reflecting oil workers. In 1973, as a key project of the Ministry of Culture, Changying filmed a feature film "Entrepreneurship" reflecting the Daqing Petroleum Congress, and specially invited Qin Yongcheng to create music for this film. Qin Yongcheng lived up to expectations, and created a number of well-known songs in his film music, such as Looking at Beijing with deep feelings, Entrepreneurial songs, and The Fragrance of Oil in Tianya Wan Li. Because of Qin Yongcheng’s outstanding contribution to the creation of oil-related music, the vast number of oil workers are familiar with the name Qin Yongcheng and affectionately call him "the composer of oil workers". In 1994, China Petroleum and Natural Gas Corporation (formerly the Ministry of Petroleum Industry) awarded Qin Yongcheng the honorary title of "composer of oil workers", and he was the only composer in China to win this honor. In 1996, China Records Corporation awarded Qin Yongcheng the "Golden Record Award" for this work, which was later included in the 20th century Chinese classics.

　　Praising the motherland and people and eulogizing the times and life are the themes of Qin Yongcheng’s life creation. It is precisely because of Qin Yongcheng’s deep patriotism, deep thoughts and feelings for the broad masses of the people, including oil workers, rich musical language based on Chinese excellent musical culture, and continuous absorption of rich nutrition and creative sources in the long-term in-depth social life that he created such immortal masterpieces represented by "I Contribute Oil to the Motherland", which are full of positive energy and the main theme of the times, and have high artistic value and appeal to both refined and popular tastes.

Through ten groups of questions and answers, this paper gives you the function and application of popular science stem cells, and shows you the important position of stem cell therapy in modern medical care.

Mother, the pilot of the boat of life, not only gave birth to us, but also promoted the reproduction of mankind. She is a great inheritor of life and a transmitter of love.

Cells, the weavers of the web of life, constitute the cornerstone of the human body, which is a miracle exhibitor with various forms and complicated functions.

The human body is a magnificent movement interwoven with countless cells, the harmonious resonance of 240 kinds and 60 trillion cells, and the subtle fusion of 4 major organizations, 36 organs and 8 major systems.

She is a special cell, but also the guardian of the source of life. She can regenerate new cells, replace aging cells and repair damaged tissues and organs. She is the mother of the cell world.

This kind of cell is the root of our life-stem cells.

With the progress of science, stem cell research has become one of the most advanced and active research directions in the global medical field.

However, for the general public, what exactly are stem cells? What does it do? What kind of people are suitable for repair intervention through stem cells? What are the risks even in treatment? This article will help you understand these questions easily through ten groups of questions and answers.

Ten questions and answers about stem cells

01

What are stem cells?

Stem cells are cells with self-renewal function and multi-directional differentiation ability.

Under certain conditions, these cells can differentiate into more than 220 different functional cells in human body. Because of its remarkable homing effect, stem cells can repair and replace damaged cells and promote organ regeneration. They are the basic cells that constitute various tissues and organs of the human body, so they are known as "the source of life" and are often called "universal cells" in the medical field.

02

What are the classifications of stem cells?

Scientific research shows that stem cells exist not only in embryos, but also in adults, which can be extracted from cord blood, umbilical cord, placenta, bone marrow, fat and other tissues.

Stem cells are divided into totipotent stem cells, pluripotent stem cells and unipotent stem cells according to their extensive differentiation ability.

Stem cells can be divided into embryonic stem cells and adult stem cells according to their stages of embryonic development.

According to the tissue type of stem cell differentiation, it can be divided into hematopoietic stem cells and mesenchymal stem cells.

03

What is stem cell therapy?

"Stem cell therapy" refers to a medical intervention that extracts stem cells from patients or uses other stem cells, cultivates them under laboratory conditions, and then transfuses them into patients through specific transplantation techniques, so as to repair the cells and tissues that have lost their functions, thus promoting their regeneration and improving their symptoms. At present, hematopoietic stem cells and mesenchymal stem cells are widely used in clinic.

04

What is the difference between autologous and allogeneic stem cells?

Autologous stem cells are derived from patients themselves, which have perfect tissue compatibility, no need for matching, high utilization rate of transplanted cells and no rejection.

Allogeneic stem cells are derived from individuals other than patients and have low immunogenicity. Autologous stem cells are not recommended for people with infectious diseases, major genetic diseases or other health problems.

05

How can stem cells be used to treat diseases?

Cells are the basic unit of life. Human life is accompanied by the process of self-replication and differentiation of stem cells from birth to growth. The ability of stem cells to treat diseases mainly stems from their biological characteristics, which include:

The ability of long-term survival and continuous self-replication;

It can differentiate across different lines and germ layers, showing high plasticity;

And its chemical tendency, that is, homing effect, provides an important biological basis for cell therapy.

06

Is stem cell therapy risky?

Compared with conventional drug therapy, stem cell therapy is considered safer and has fewer side effects. But this does not mean that the risk is zero. Looking at stem cell therapy objectively, the following are some main risks of stem cell therapy:

Tumor development: If stem cells divide or differentiate into abnormal cells uncontrollably, it may lead to cancer. This mainly applies to embryonic or fetal stem cells, or reprogrammed stem cells, because the risk is based on their pluripotency.

Immune rejection: The body may regard foreign stem cells as a threat and attack them, leading to inflammation and injury. This is more likely to happen in hematopoietic stem cells (HSC).

Infection or complications related to invasive medical procedures: Stem cell therapy may lead to infection or complications related to invasive medical procedures.

Drug interaction: Stem cell therapy may have unpredictable interactions with other drugs taken by patients, which may lead to adverse drug interactions.

Unconfirmed or untested stem cell therapy: There is also the risk that unscrupulous practitioners provide unconfirmed or untested stem cell therapy, which may be unsafe or effective.

The effect of treatment is uncertain: patients should also realize that stem cell therapy does not guarantee a cure, and in some cases, it may not be effective at all. Stem cell therapy may not provide lasting results, and patients may need additional treatment.

It should be noted that these risks may be different due to individual differences, treatment methods, stem cell types and other factors. Before receiving stem cell therapy, patients should fully discuss these risks with doctors and weigh the potential benefits and risks of treatment.

07

What diseases can stem cell therapy treat?

Stem cell therapy is mainly used in the fields of treatment, health care and beauty, and it is also used to improve some refractory diseases.

Heart disease: Stem cells can regenerate damaged heart cells and maintain the health and vitality of the heart through a specific process of induced differentiation in the treatment of heart disease.

Prevention and treatment of Alzheimer’s disease: Injecting induced differentiated stem cells can replace aging brain cells and improve cognitive function.

Treatment of liver cirrhosis: generate liver cells through differentiation, and promote the regeneration and repair of liver cells.

Cancer treatment: Directionally differentiated stem cells can enhance the body’s immune function and help fight tumors.

Treatment of premature ovarian failure: Stem cell therapy can restore ovarian function, promote the repair of damaged tissues, improve ovarian microenvironment, enhance reproductive capacity, prevent follicular atresia and promote follicular renewal.

Male hypofunction: Stem cell therapy can repair the aging of reproductive system, improve sexual function, maintain the balance of sex hormones, reduce nocturia, relieve the symptoms of prostatic hyperplasia, and help prevent prostate hypertrophy and other problems.

Enhance muscle function: with the increase of age, muscle function weakens, strength and relaxation function decline, and the body is bloated. Stem cell therapy can improve muscle function, enhance strength, improve body shape and show youthfulness.

08

What is the effect of stem cell therapy?

Stem cell therapy can be carried out by systemic infusion or fixed-point intervention. Clinicians adopt appropriate cell types and treatment strategies according to patients’ health status and disease needs.

Because this treatment can directly intervene in the cause of disease, avoid other physical injuries that may be caused by drugs and surgery, and help regulate the sub-health state, the effect is usually not limited to treating diseases, but also improving the overall function.

09

Is there an age limit for stem cell transfusion?

Traditionally, some types of stem cell transplantation, such as allogeneic bone marrow transplantation, often have age restrictions, and it is usually recommended to be 50 years old or under 45 years old. However, with the progress of medical technology, this limitation is being broken.

For example, it has been reported that a 71-year-old patient successfully received autologous hematopoietic stem cell transplantation, and a 69-year-old woman also successfully received her son’s hematopoietic stem cell transplantation.

These cases show that under proper medical conditions and monitoring, elderly patients may also successfully receive stem cell transfusion therapy, which proves that the age limit is gradually relaxing.

10

What are the taboo populations of stem cells?

Patients with advanced malignant brain tumors, especially brain tumors;

Patients with shock or general failure with abnormal vital signs (requiring disease correction) and those who do not cooperate with the examination;

Patients with heart, lung, liver, kidney and other important organ dysfunction (multiple organ dysfunction syndrome);

Patients with dysfunction of coagulation mechanism;

Patients with severe local infection;

Patients with positive serological results (such as HIV, hepatitis B, syphilis, etc.);

People with high allergic constitution or severe allergic history;

People with nervous system diseases or diseases that have not been diagnosed;

This group is in a special situation and has uncontrollable risks, so it needs careful diagnosis and treatment.

Write it at the end

Stem cells have excellent regeneration and repair functions, and these abilities will gradually weaken with age. Therefore, it is an increasingly popular choice to store healthy stem cells as early as possible, which will provide the possibility for future health management and disease treatment.

The 21st century will be the era of cell therapy, and the application of stem cells and immune cells is expected to play an important role in clinical treatment.

However, at present, except for the mature clinical application of hematopoietic stem cell transplantation, other types of stem cell therapy are mostly in the research stage, and strictly designed clinical trials are needed to prove their clinical advantages, safety and effectiveness, which need further study.

Moreover, non-compliant and eager stem cell therapy and research not only threaten the safety of patients, but also hinder the improvement of stem cell therapy and its research level, which needs the attention of legal supervision, and patients with hope in stem cell therapy should also be alert to fraud and pay attention to its development and related policies and regulations.

　　CCTV News:Every year before the Spring Festival, it is the peak season for all kinds of express delivery. Since Spring Festival travel rush started on January 7th, the daily postal express delivery volume has been over 300 million pieces, with a peak of over 400 million pieces. What changes have been made to the express delivery capacity that will be tight in previous years? Can the express delivery business be guaranteed during the holidays? Is the way home by express delivery smooth?

　　At 6: 30 in the morning, at this express outlet in Zhongguancun, the person in charge, Lei Liping, simply said a few words, and the express buddy immediately threw himself into the sorting work.

　　As the nearest express terminal service point to customers, from 4: 00 in the morning, there are trucks coming into the field one after another, and express parcels sent from all over the country to nearby areas are pulled from the transit point. The express parcels waiting to be sorted and delivered quickly piled up a hill.

　　"hurry up! Hurry up! " This is the word that reporters hear the most frequently at the scene. Lei Liping told reporters that near the Spring Festival, the peak of express delivery has been ushered in recent days. Because most of them are fresh food, gifts and other new year’s goods, in order to ensure the timeliness, the express delivered from all over the country in the morning should be delivered to customers before noon. Nearly 50 courier brothers in this outlet have to arrive at their posts before 6: 30 in the morning, and breakfast can only be solved.

　　Less than 8 o’clock, the five express parcels sent in the morning have been sorted.

　　Go all out to ensure the express delivery "Spring Festival travel rush", the grass-roots outlets at the end of delivery operate efficiently, and the circulation at the end is smooth. Then, what is the transition in express delivery with a wider business scope?

　　The reporter saw in a courier transfer near the Capital Airport that dozens of unloading ports were full of trucks. On the other hand, there are long queues of vehicles waiting for unloading.

　　Handling 600,000 peak packages per day is definitely not possible by manpower alone. The reporter saw at the scene that the automatic sorting equipment helped a lot. After unloading, these parcels were transported to the automatic sorting machine, and more than 600 sorting ports could be automatically divided into different parcel bags according to the area codes on the face sheet.

　　Save enough cars and people. In order to cope with the peak of express delivery during the Spring Festival, recently, many express delivery companies have proposed "no fighting during the Spring Festival" to ensure the smooth flow of express logistics.

　　In Beijing Xinfadi Fruit Wholesale Market, Wei Dongwen, who is in charge of contacting the truck service for merchants, asked about the shipment of merchants and contacted the truck by phone.

　　Wei Dongwen told reporters that people have been going home for the New Year these days, but they have also left enough manpower to ensure the delivery needs of customers. During the Spring Festival, there are still many courier brothers who are ready to stick to their posts to ensure that the courier service during the festival is not interrupted.

　　Shi Jianting and Zhang Huanrong, couples from Linfen, Shanxi, have stayed at the delivery line for four consecutive Spring Festival. The couple planned that after the 14th day of the first month, the list was running out, and they would go home at the wrong peak.

　　The reporter learned in the interview that a number of measures have been introduced in various places to actively respond to the express delivery demand during the holiday season. Some express delivery companies start the "night delivery" mode, extend the delivery time at night, and give priority to timely delivery of drugs, epidemic prevention materials and food. Jiangsu issued 35 million yuan of government subsidies for the postal express delivery industry to stabilize and return to work, helping the postal express delivery industry to accelerate its recovery. In Luzhou, Sichuan, the bus driver undertakes the task of delivering the express delivery. After receiving the express delivery from the postal transport vehicle, the bus driver sorts and delivers the express delivery to the Jintong Post Express Station in each village to get through the "last mile" of the parcel entering the village.

With the popularity of electric vehicles, electric car charger has become an indispensable accessory for every electric vehicle user. However, there are many kinds of chargers in the market. How to choose a charger that suits you? The following will be popular science for everyone from several key aspects.

* * First, understand the battery type of electric vehicles * *

First of all, we need to know what kind of batteries our electric cars use, such as lead-acid batteries and lithium batteries. Different types of batteries have different requirements for chargers, so the choice of chargers must match the battery type.

Execution linkage, smashing inter-provincial fake wine criminal gangs

—— On-the-spot report on the case of investigating and handling the production and sale of counterfeit "Niulanshan" registered trademark liquor in Haining, Zhejiang Province

China Quality News Network News "The manufacture and sale of fake wine not only infringes on the trademark rights of merchants, but also brings food safety risks, which is extremely harmful to society and must not be tolerated!" After half a year’s careful investigation, Haining Public Security Bureau of Zhejiang Province and Haining Market Supervision Bureau jointly acted, and recently successfully destroyed an inter-provincial criminal gang that produced and sold counterfeit "Niulanshan" registered trademark liquor, and arrested 22 suspects, involving a total amount of 10,000 yuan in Wu Bai.

Winery counterfeiting provides clues

At the beginning of 2021, Xinyoutai Liquor Industry, a distributor of Niulanshan Winery in Haining, contacted the Comprehensive Administrative Law Enforcement Team of Haining Municipal Market Supervision Bureau (hereinafter referred to as the Law Enforcement Team), saying that there may be counterfeit "Niulanshan" liquor in Haining, but the specific situation is unknown, and there is neither direct evidence nor directional clues. After receiving the clue provided by the dealer, the comprehensive law enforcement team decided, through research and analysis, to keep continuous attention on the clue, strengthen daily supervision and inspection, and gradually grasp the first-hand situation through targeted troubleshooting.

In the process of obtaining evidence, law enforcement officers, as usual,the sameInspected, but paid special attention to the sales of "Niulanshan" liquor. The "Niulanshan" liquor in the canteen is placed on a small shelf far from the door. After inspection, law enforcement officers felt that there was something wrong: there was no difference between the packaging boxes and bottle labels of these wines and genuine Niulanshan liquor, and the outer packaging was printed with "Niulanshan aged liquor" and marked with "net alcohol content of 42% vol: 500ml, production date: 201910202, place of origin: Langfang City, Hebei Province (2), entrusted party: Chengdu production base of Niulanshan Distillery of Beijing Shunxin Agricultural Co., Ltd.".

After on-site inquiry, the parties prevaricated and could not tell the source. Law enforcement officers took measures to register and preserve 137 bottles of liquor in advance.

"No." At this time, the canteen operator truthfully confessed: "In January, an agent who claimed to be’ Niulanshan’ liquor came to our store to sell it and said that it could be delivered to the door. It was a little cheaper than others, and we believed that he had entered his wine." In addition, during the inspection, law enforcement officers found that other nearby snack bars for migrant workers were also supplied by this person. According to the judgment of the confession law enforcement officers, the dealers of counterfeit liquor aimed at specific sales targets and made targeted door-to-door sales. The counterfeit liquor flowing into the market was definitely not limited to the number that had been detained, and immediately decided to inform the law enforcement team of the clues of the case. After receiving the notification, the law enforcement team immediately organized law enforcement personnel to conduct a comprehensive network investigation in the incident area. Through the network-pulling investigation, they gradually grasped the micro-signal of the dealer and the preliminary illegal clues.

In the banking field, the transaction limit of bank cards can be adjusted.The feasibility and specific way of this adjustment depends on many factors, including bank policies, card types, customer needs and authentication.

First of all, different types of bank cards, such as debit cards and credit cards, may have different adjustment rules and ranges of transaction limits. For debit cards, usually the transaction limit mainly includes daily withdrawal limit, transfer limit and so on. The transaction limit of credit card may include consumption limit, cash withdrawal limit and so on.

The original intention of the bank to set the transaction limit is mainly to ensure the safety of customers’ funds and prevent large capital losses caused by stolen bank cards or misoperation. However, when customers have special needs, such as large transactions, they can apply for adjusting the limit.

There are several ways to adjust the transaction limit of bank cards:

1. Online banking: Many banks provide online banking services. Customers can log in to their online banking accounts and find the function of adjusting the trading limit in the relevant setting options. In this way, customers can operate according to the prompts, and usually need to input some verification information, such as SMS verification code and dynamic password.

2. Mobile banking: Similar to online banking, mobile banking applications usually have the function of adjusting transaction limits. Customers only need to open the bank’s application on their mobile phones and follow the instructions.

3. Bank counter: This is a more traditional but direct and effective way. Customers can bring their valid identity documents and bank cards to the bank counter and apply to the staff for adjusting the transaction limit. The staff will handle it according to the needs of customers and the regulations of the bank.

It should be noted that no matter which way the transaction limit is adjusted, the bank may strictly verify the identity of the customer to ensure that it is the true will of the customer. In addition, the adjusted trading limit is not unlimited, and the bank will set it reasonably according to the customer’s credit status, source of funds and other factors.

Take the adjustment of debit card and credit card transaction limit of a bank as an example to provide you with a simple comparison table:

In short, the transaction limit of bank cards can be adjusted, but customers should make reasonable choices according to their actual needs and risk tolerance when applying for adjustment, and at the same time abide by the relevant regulations and procedures of banks.
