bus line: No.54, the whole journey is about 9.0km
1. Take No.54 from Xindian, pass 19 stops, and reach bus Rende station
2. Walk about 210m to Fuzhou citizen service center
2. Shopping guide is an important part of the whole sales work and the process of realizing the exchange of goods and currency. Shopping guide is the key person to realize this key leap. It is a difficult process for customers to take money out of their pockets to buy the company's procts. The shopping guide must have sufficient reasons to make customers willing to buy procts and make them feel that the procts they buy are worth the money. To achieve this, we must explain the functions of the procts in detail and patiently, and let the customer understand that this function is exactly what he needs. To achieve this, we need a lot of promotion means and skills in the process of promotion
in addition, the shopping guide is the only manufacturer personnel that customers can contact. The shopping guide reflects the image of the company. Before customers have a deep understanding of the procts, their perception of the company directly comes from the feeling and impression given by the shopping guide. Good shopping guide service can cultivate a large number of loyal customers and improve brand awareness for the company, and can cultivate potential market, because good promotion service can make customers do the following three points:
Customer repeat purchase - customer related purchase - customer recommendation purchase
famous sales number rule: 1:8:25:1, that is, affect one customer, It can indirectly affect 8 customers, and make 25 customers proce purchase intention, and 1 customer achieve purchase behavior. And so on, if you offend a customer, it will also bring corresponding losses, and the losses need you to pay twice the effort to make up. It can be seen that to provide customers with quality procts and satisfactory service is an important responsibility of every shopping guide

6. Chinese mathematics
China is one of the ancient civilizations in the world, which is located in the east of Asia and on the west coast of the Pacific Ocean. The development of mathematics in China has a long history and brilliant achievements. Now we will describe it in sections according to the development of history< The Yellow River Basin and the Yangtze River Basin were the cradle of Chinese culture in the pre Qin period. About 2000 BC, the Xia Dynasty, the first slave state in the middle and lower reaches of the Yellow River, came into being. Later, there were Shang and Yin dynasties (about 1500 B.C. - 1027 B.C.) and Zhou Dynasty (1027 B.C. - 221 B.C.). In history, it is also known as the period from the eighth century BC to the establishment of Qin Dynasty (221 B.C.)
according to the book of changes, it is said that in ancient times, the rule was made by tying a rope, and later sages changed it by writing a deed. There are many counting characters in oracle bone inscriptions unearthed in Yin Ruins. From one to ten, and hundred, thousand and ten thousand are special counting characters. There are 13 independent symbols in total. The counting is written in compound script. Among them, there is decimal system, and the largest number is thirty thousand
calculation is an ancient Chinese calculation tool, and this calculation method is called calculation. It's impossible to test the time when Suan Chou came into being, but it's certain that Suan Chou was very common in the spring and Autumn period< There are vertical and horizontal ways to count with arithmetic:
123456789
when it represents a multi digit number, the decimal value system is adopted, and the number of each value is arranged from left to right, alternating vertically and horizontally [the rule is: one vertical and ten horizontal, one hundred stand and one thousand stiff, one thousand and ten face each other, ten thousand and one hundred are equal], and zero is represented by vacancy. The algorithm establishes good conditions for addition, subtraction, multiplication and division< It was not until the end of the Yuan Dynasty in the 15th century that the abacus was graally replaced by the abacus
in the aspect of geometry, it is said in Shiji xiabenji that Xiayu had used such mapping and measuring tools as rules, moments, accuracies and ropes in his flood control, and that he had already discovered the special case of the Pythagorean theorem, which is called Pythagorean theorem in the West. During the Warring States period, KAOGONGJI, written by Qi people, summarized the specifications of handicraft technology at that time, including some measurement contents, and involved some geometric knowledge, such as the concept of angle
the contention of a hundred schools of thought ring the Warring States period also promoted the development of mathematics, and some schools also summarized and summarized many abstract concepts related to mathematics. The famous ones are the definitions and propositions of some geometric terms in Mojing, such as "circle, one middle, the same length", "flat, the same height" and so on. Mohism also gives the definition of finite and infinite Zhuangzi records the famous theories of Huishi and others, and the propositions put forward by Huan Tuan, Gongsun long and other debaters, emphasizing abstract mathematical thoughts, such as "the greatest is called the big one, and the smallest is called the small one" and "the hammer of a foot is half of the day, and it will last forever". The definition of many geometric concepts, the thought of limit and other mathematical propositions are quite valuable mathematical thoughts, but this new thought which attaches importance to abstraction and logical rigor has not been well inherited and developed< In addition, the book of changes, which tells the eight diagrams of yin and Yang and predicts good or bad luck, has sprouted combinatorial mathematics and reflects the idea of binary system< This period includes more than 1000 years of mathematical development from the Qin and Han Dynasties to the Sui and Tang Dynasties, and the dynasties they experienced are Qin, Han, Wei, Jin, northern and Southern Dynasties, Sui and Tang. Qin and Han Dynasties are the formation period of ancient Chinese mathematics system. In order to systematize and theorize the constantly rich mathematical knowledge, special books on mathematics have appeared one after another< There are two main achievements in Mathematics in Zhoubi Suanjing, an astronomical work compiled in the last years of the Western Han Dynasty (the first century BC): (1) the special case and general form of Pythagorean theorem are put forward 2) Chen Zi's method of measuring the height and distance of the sun was the pioneer of the later double difference method. In addition, there are more complex square root problem and fraction operation<
"nine chapters of arithmetic" is an ancient classic work of mathematics, which was compiled, supplemented and revised by several generations. It was written in the early Eastern Han Dynasty [the first century BC]. The book is compiled in the form of problem set, with a total of 246 problems and their solutions. It is divided into nine chapters, namely, Fang Tian, Su MI, Shou Fen, Shao Guang, Shang Gong, Jun Shu, Ying Xu, equation and Pythagorean. The main contents include four points and proportion algorithm, calculation of various areas and volumes, calculation of Pythagorean measurement, etc. In terms of algebra, the concept of negative number and the law of addition and subtraction of positive and negative numbers introced in the chapter of equation are the earliest records in the history of mathematics in the world; The solution of linear equations in the book is basically the same as that taught in middle school. As far as the characteristics of "nine chapters of arithmetic" are concerned, it pays attention to application and combines theory with practice, forming a mathematical system centered on calculation, which has a far-reaching influence on ancient Chinese calculation. Some of its achievements, such as the decimal value system, modern skills, surplus and deficiency skills, were also spread to India and Arabia, and through these countries to Europe, which promoted the development of mathematics in the world. During the Wei and Jin Dynasties, Chinese mathematics developed greatly in theory. The work of Zhao Shuang and Liu Hui is considered to be the beginning of ancient Chinese mathematical theory system. Zhao Shuang is one of the earliest mathematicians who proved the mathematical theorem and formula in ancient China. He made a detailed annotation on Zhoubi Suanjing. Liu Hui's annotation of "nine chapters of arithmetic" not only explains and deces the methods, formulas and theorems of the original book, but also has many innovations in the process of discussion. He also wrote "island Suanjing" and applied the technique of double difference to solve the problems related to measurement. One of Liu Hui's important works is to establish the circle cutting technique, which lays a theoretical foundation and provides a scientific algorithm for the research of PI
ring the northern and Southern Dynasties, the society was in a state of war and division for a long time, but the development of mathematics was still vigorous Sunzi Suanjing, xiahouyang Suanjing and zhangqiujian Suanjing are the works of this period Sun Tzu Suanjing gives the problem of "things don't know numbers", which leads to solving the problem of first-order congruence group The "hundred chickens problem" in Zhang Qiujian's Suanjing leads to the problem of three unknown indefinite equations< In this period, the work of Zu Chong and Zu Rihuan was the most representative. Based on Liu Hui's annotation of nine chapters on arithmetic, they greatly pushed forward the traditional mathematics and became the model of paying attention to mathematical thinking and mathematical reasoning. They also made outstanding contributions to astronomy. According to historical records, they have three main achievements in Mathematics: (1) the calculation of PI is accurate to the sixth decimal place, and the result is 3.1415926 & lt; π& lt; 1415927 π The density ratio is 355 / 113 2) We obtain Zu Rihuan's theorem and the formula of sphere volume 3) The solutions of quadratic and cubic equations are developed< The construction in Sui Dynasty promoted the development of mathematics objectively. In the early Tang Dynasty, Wang Xiaotong wrote the ancient calculation Scripture, which mainly discussed the calculation of earthwork in civil engineering, the division and acceptance of engineering, and the calculation of warehouse and cellar
in Tang Dynasty, mathematics ecation has made great progress. In 656, the Guozijian School of mathematics was set up with a doctor of mathematics and teaching assistants. Li Chunfeng, the imperial historian, compiled and annotated the ten books of Suan Jing [including Zhoubi Suan Jing, Jiuzhang Suan Jing, Dao Suan Jing, Sunzi Suan Jing, zhangqiujian Suan Jing, xiahouyang Suan Jing, Jigu Suan Jing, wucao Suan Jing, Wujing Suan Jing and Zhuozhu], It's a textbook for students in the math school. It plays an important role in preserving ancient mathematics classics
in addition, e to the needs of the calendar in the Sui and Tang Dynasties, the secondary interpolation method was established, which laid the foundation for the high-order interpolation method in the song and Yuan Dynasties. In the late Tang Dynasty, the computing technology has been further improved and popularized. There are many kinds of practical arithmetic books, and the multiplication and division algorithm is simple< In the heyday of the song and Yuan Dynasties, after the fall of the Tang Dynasty, the Five Dynasties and ten states were still fighting with warlords. Until the Northern Song Dynasty unified China, agriculture, handicraft instry and commerce flourished rapidly, and science and technology advanced by leaps and bounds. From the 11th century to the 14th century [song and Yuan Dynasties], the mathematics of calculation reached its peak, which was the heyday of the unprecedented prosperity and fruitful of ancient Chinese mathematics. During this period, a number of famous mathematicians and mathematical works appeared, which are listed as follows: Jia Xian's "Yellow Emperor's nine chapters algorithm" in the middle of the 11th century, Liu Yi's "discussing ancient roots" in the middle of the 12th century, Qin Jiushao's "Shu Shu's nine chapters" in the middle of the 12th century, Li Ye's "measuring circle and sea mirror" and "Yigu Yan Duan" in the middle of the 12th century, Yang Hui's "detailed explanation of nine chapters algorithm" in the middle of the 12th century Daily algorithm [1262] and Yang Hui algorithm [1274-1275], Zhu Shijie's Enlightenment of arithmetic [1299] and Siyuan Yujian [1303], etc. Mathematics in song and Yuan Dynasties reached the peak of ancient Chinese mathematics in many fields, even the world mathematics at that time. The main works are as follows:
1< It is the first time in the history of Chinese mathematics to introce symbols and use symbolic operations to solve the problem of establishing higher-order equations< 3. Dayan's solution, that is, the solution of the system of first-order congruences, is now called Chinese remainder theorem< 4. The technique of recruitment and accumulation, that is, high-order interpolation and summation of high-order arithmetic progression. In addition, other achievements include the new development of Pythagorean method, the study of spherical right triangle, the study of magic square, the application of decimal fraction, the appearance of abacus, etc. During this period, the folk mathematics ecation also developed, and the exchange of mathematics knowledge between China and Islamic countries also developed< This period lasted more than 500 years from the establishment of Yeming Dynasty in the 14th century to the end of Qing Dynasty in the 20th century. Besides abacus, mathematics is in a state of overall decline, which involves the limitations of Chinese mathematics, the deletion of mathematics content in the examination system of the 13th century, the eight section examination system of Daxing in the Ming Dynasty and other complex problems. Many Chinese and foreign mathematics historians still discuss the reasons involved. At the end of the 16th century, Western elementary mathematics began to be introced into China, which brought about a situation of integration of Chinese and Western mathematics research. After the Opium War, modern higher mathematics began to be introced into China, and Chinese mathematics turned into a period of learning western mathematics. It was not until the end of the 19th century that the study of modern mathematics in China really began
the greatest achievement of Ming Dynasty was the popularization of abacus, and there were many books about abacus. When Cheng Dawei's shufa Tongzong (1592) came out, the theory of abacus had become a system, marking the completion of the transformation from planning to abacus. However, e to the popularity of abacus, the ancient mathematics based on abacus was graally lost, and mathematics stagnated for a long time
in the Sui and early Tang Dynasties, Indian mathematics and astronomy were introced to China, but their influence was relatively small. At the end of the 16th century, Western missionaries began to work in China and translated many western mathematics monographs with Chinese scholars. Among them, the first and influential one is the translation by Italian missionaries Matteo Ricci and Xu Guangqi
China is one of the ancient civilizations in the world, which is located in the east of Asia and on the west coast of the Pacific Ocean. The development of mathematics in China has a long history and brilliant achievements. Now we will describe it in sections according to the development of history< The Yellow River Basin and the Yangtze River Basin were the cradle of Chinese culture in the pre Qin period. About 2000 BC, the Xia Dynasty, the first slave state in the middle and lower reaches of the Yellow River, came into being. Later, there were Shang and Yin dynasties (about 1500 B.C. - 1027 B.C.) and Zhou Dynasty (1027 B.C. - 221 B.C.). In history, it is also known as the period from the eighth century BC to the establishment of Qin Dynasty (221 B.C.)
according to the book of changes, it is said that in ancient times, the rule was made by tying a rope, and later sages changed it by writing a deed. There are many counting characters in oracle bone inscriptions unearthed in Yin Ruins. From one to ten, and hundred, thousand and ten thousand are special counting characters. There are 13 independent symbols in total. The counting is written in compound script. Among them, there is decimal system, and the largest number is thirty thousand
calculation is an ancient Chinese calculation tool, and this calculation method is called calculation. It's impossible to test the time when Suan Chou came into being, but it's certain that Suan Chou was very common in the spring and Autumn period< There are vertical and horizontal ways to count with arithmetic:
123456789
when it represents a multi digit number, the decimal value system is adopted, and the number of each value is arranged from left to right, alternating vertically and horizontally [the rule is: one vertical and ten horizontal, one hundred stand and one thousand stiff, one thousand and ten face each other, ten thousand and one hundred are equal], and zero is represented by vacancy. The algorithm establishes good conditions for addition, subtraction, multiplication and division< It was not until the end of the Yuan Dynasty in the 15th century that the abacus was graally replaced by the abacus
in the aspect of geometry, it is said in Shiji xiabenji that Xiayu had used such mapping and measuring tools as rules, moments, accuracies and ropes in his flood control, and that he had already discovered the special case of the Pythagorean theorem, which is called Pythagorean theorem in the West. During the Warring States period, KAOGONGJI, written by Qi people, summarized the specifications of handicraft technology at that time, including some measurement contents, and involved some geometric knowledge, such as the concept of angle
the contention of a hundred schools of thought ring the Warring States period also promoted the development of mathematics, and some schools also summarized and summarized many abstract concepts related to mathematics. The famous ones are the definitions and propositions of some geometric terms in Mojing, such as "circle, one middle, the same length", "flat, the same height" and so on. Mohism also gives the definition of finite and infinite Zhuangzi records the famous theories of Huishi and others, and the propositions put forward by Huan Tuan, Gongsun long and other debaters, emphasizing abstract mathematical thoughts, such as "the greatest is called the big one, and the smallest is called the small one" and "the hammer of a foot is half of the day, and it will last forever". The definition of many geometric concepts, the thought of limit and other mathematical propositions are quite valuable mathematical thoughts, but this new thought which attaches importance to abstraction and logical rigor has not been well inherited and developed< In addition, the book of changes, which tells the eight diagrams of yin and Yang and predicts good or bad luck, has sprouted combinatorial mathematics and reflects the idea of binary system< This period includes more than 1000 years of mathematical development from the Qin and Han Dynasties to the Sui and Tang Dynasties, and the dynasties they experienced are Qin, Han, Wei, Jin, northern and Southern Dynasties, Sui and Tang. Qin and Han Dynasties are the formation period of ancient Chinese mathematics system. In order to systematize and theorize the constantly rich mathematical knowledge, special books on mathematics have appeared one after another< There are two main achievements in Mathematics in Zhoubi Suanjing, an astronomical work compiled in the last years of the Western Han Dynasty (the first century BC): (1) the special case and general form of Pythagorean theorem are put forward 2) Chen Zi's method of measuring the height and distance of the sun was the pioneer of the later double difference method. In addition, there are more complex square root problem and fraction operation<
"nine chapters of arithmetic" is an ancient classic work of mathematics, which was compiled, supplemented and revised by several generations. It was written in the early Eastern Han Dynasty [the first century BC]. The book is compiled in the form of problem set, with a total of 246 problems and their solutions. It is divided into nine chapters, namely, Fang Tian, Su MI, Shou Fen, Shao Guang, Shang Gong, Jun Shu, Ying Xu, equation and Pythagorean. The main contents include four points and proportion algorithm, calculation of various areas and volumes, calculation of Pythagorean measurement, etc. In terms of algebra, the concept of negative number and the law of addition and subtraction of positive and negative numbers introced in the chapter of equation are the earliest records in the history of mathematics in the world; The solution of linear equations in the book is basically the same as that taught in middle school. As far as the characteristics of "nine chapters of arithmetic" are concerned, it pays attention to application and combines theory with practice, forming a mathematical system centered on calculation, which has a far-reaching influence on ancient Chinese calculation. Some of its achievements, such as the decimal value system, modern skills, surplus and deficiency skills, were also spread to India and Arabia, and through these countries to Europe, which promoted the development of mathematics in the world. During the Wei and Jin Dynasties, Chinese mathematics developed greatly in theory. The work of Zhao Shuang and Liu Hui is considered to be the beginning of ancient Chinese mathematical theory system. Zhao Shuang is one of the earliest mathematicians who proved the mathematical theorem and formula in ancient China. He made a detailed annotation on Zhoubi Suanjing. Liu Hui's annotation of "nine chapters of arithmetic" not only explains and deces the methods, formulas and theorems of the original book, but also has many innovations in the process of discussion. He also wrote "island Suanjing" and applied the technique of double difference to solve the problems related to measurement. One of Liu Hui's important works is to establish the circle cutting technique, which lays a theoretical foundation and provides a scientific algorithm for the research of PI
ring the northern and Southern Dynasties, the society was in a state of war and division for a long time, but the development of mathematics was still vigorous Sunzi Suanjing, xiahouyang Suanjing and zhangqiujian Suanjing are the works of this period Sun Tzu Suanjing gives the problem of "things don't know numbers", which leads to solving the problem of first-order congruence group The "hundred chickens problem" in Zhang Qiujian's Suanjing leads to the problem of three unknown indefinite equations< In this period, the work of Zu Chong and Zu Rihuan was the most representative. Based on Liu Hui's annotation of nine chapters on arithmetic, they greatly pushed forward the traditional mathematics and became the model of paying attention to mathematical thinking and mathematical reasoning. They also made outstanding contributions to astronomy. According to historical records, they have three main achievements in Mathematics: (1) the calculation of PI is accurate to the sixth decimal place, and the result is 3.1415926 & lt; π& lt; 1415927 π The density ratio is 355 / 113 2) We obtain Zu Rihuan's theorem and the formula of sphere volume 3) The solutions of quadratic and cubic equations are developed< The construction in Sui Dynasty promoted the development of mathematics objectively.

7. 1. Target preparation
generally speaking, people's investment in gold can be divided into short-term investment, medium-term investment and long-term investment; In terms of profit requirements, it can be divided into two types: value preservation and value increment; It can be divided into investment and speculation. The above factors, combined with the fluctuation of gold price, the funds available to families, the personal familiarity with gold price and gold varieties, and the personal investment style, can basically determine the goal of their own gold investment<
2. Portfolio preparation
gold is one of the family's different investment targets. Different investment objectives and risk control requirements, and different investment targets in different time periods will lead to different proportions of gold in the family's portfolio. For ordinary families, under normal circumstances, the proportion of gold in the total household assets should not exceed 10%. Only on the premise that gold is expected to rise sharply can this ratio be appropriately increased<
3. Variety preparation
the target of fried gold is divided into physical gold and "paper gold". Physical gold has better hedging and liquidity than paper gold, but its value-added space is smaller than paper gold. On the contrary, "paper gold" investment income is often greater than physical gold, so it has a very stable investment value-added function. Generally speaking, physical gold is more suitable for middle-aged and elderly investors to participate in, but also suitable for personal collection or gifts to relatives and friends, and "paper gold" is the preferred tool for indivial gold speculators<
4. Information preparation
because there are many factors that affect the rise and fall of gold price, and from a global perspective, the trading of gold market is 24 hours a day, so the requirement of investment in gold for information is relatively high. At present, there are more and more channels for investors to obtain gold related information. In addition to bank outlets, many financial newspapers, magazines and websites have relevant information
5. Risk preparation
although gold has a noble identity, it will also go up and down. Gold investment and gold storage are two different things. Blind entry will lead to deep hold up. Therefore, it is very important for investors to protect their own rights and interests while preventing market risks<
three skills of gold investment
skill 1: portfolio investment
gold price usually runs in reverse with most investment varieties. Adding an appropriate proportion of gold into the asset portfolio can maximize the dispersion of risks, effectively resist the sharp shrinkage of assets, and even increase the value of assets
the asset portfolio recommended by the financial planner is: cash + bonds + equity assets + gold. In this portfolio, the proportion of gold accounts for 10% - 20%, which can be increased or decreased appropriately according to its own asset status. When the risks of the financial system (such as bad debts, real estate bubbles and inflation) increase, the proportion of gold investment should be adjusted. When the atmosphere of local war grows stronger, the proportion of gold investment should also be increased
skill 2: consider the exchange rate
when the domestic currency appreciates, people can buy cheaper gold goods in foreign countries, because the price of gold at home does not move or fall, which does not mean that the value of gold itself will fall correspondingly, but may be the result of the exchange rate changes between local currency and foreign currency. Therefore, investment in gold requires a certain amount of foreign exchange knowledge, otherwise do not invest a lot in gold<
skill 3: buy in batches
strategically speaking, we should follow the upward trend of bull market, that is, operate in one direction and insist on buying in the callback. Because the lowest point can be met but not sought, it is necessary to buy in batches, wait to rise and sell, and then wait for the next buying opportunity

8. What you read depends on your existing foundation and the type of trader you want to be.
if you want to do short-term trading, read the Japanese candle chart, index strategy and other basic knowledge, combined with the accumulation of market sense, it is enough to do short-term trading in the day, and the foundation is not very high, The key is to understand the real-time changes of the market in order to deal with them in real time.
if you want to do trend trading, you'd better supplement some complete theoretical knowledge, such as wave theory, Dow Theory, Gann's trading rules and so on; Trend trading is between "immediate response" and "trend prediction"; If you have already formed your own trading style foundation, you might as well read some systematic trading books to improve it; We need to learn from disk analysis
if we want to do basic transactions, we need to have considerable analytical ability and foresight in politics, economy, currency, international trade and other aspects, and be able to analyze and judge the supply and demand changes of hedging or physical objects such as gold and silver from the changes of policy events, economic changes or monetary measures of various countries; As for books, there is nothing fixed about economic and trade policies, money, gold and silver, etc. the key to comprehensive financial books is whether they can be read and understood; After learning, you need to understand the impact of various reports and financial events or economic events on gold and silver prices

9. Those who are not familiar with the stock market often have two different wrong views. One is that the stock market is a trap, and you can't get away with it; On the other hand, they regard the stock market as a place to pick up money at will, thinking that they can make a fortune in a flash. Generally speaking, most of the new investors hold the first attitude. However, when they try to enter the stock market with small gains, their confidence suddenly increases. They often throw all their heart and soul into the market without any scruples. As a result, they lose miserably. So they sigh about the deception of the stock market, or scold the change of policy, making them deeply involved in the stock market
therefore, new investors should have a good attitude before entering the market. First, don't be afraid of the stock market. The growth of the stock market in the world shows that the development of the stock market is concive to promoting social and economic development. In the long run, the trend of the stock market is also upward. China's securities market is becoming more and more perfect. As an emerging market, there is no doubt about the growth space and development prospect of China's stock market. Second, don't have unrealistic fantasies. An important reason why many people suffer losses in the stock market is that they have high expectations. In fact, although the stock market will rise and fall greatly in a period of time, from the basic trend, its rising speed is basically consistent with the country's economic growth. In this sense, it is difficult to achieve a rate of return that greatly exceeds the level of economic development. Moreover, there are always risks in the stock market. The stock price is changing rapidly. No one can accurately predict the changes of the market. It is almost impossible to win without losing. If the market participants do not have such psychological preparation, not to mention that they may lose money, even if they can make money, it is not worth worrying all day and having trouble sleeping and eating
after adjusting their mentality, new shareholders should also consider their own financial strength. If you have a rich income and a wealthy family, you can naturally invest part of your accumulated money in stocks. For the investors who are living in a tight life and have a heavy financial burden on their families, it's time to weigh up the gains and losses, and never borrow money to invest in stocks. Because different sources of funds tend to form different investment mentality. Generally speaking, the capital entering the stock market is your own surplus. Even if you are "trapped" in the stock market, you will not affect your life, so you can be more calm. If your money is borrowed, when the deadline is approaching, the performance of the stock market is often prone to irrational behavior, which often leads to chasing up and down
new entrants should also consider whether they have enough energy. Securities investment is a kind of intellectual behavior, so after China's accession to the WTO, it will make people worry and may be frustrated at any time. The profit and loss caused by the fluctuation of the stock market must constantly stimulate people's nerves and affect people's emotions. Therefore, investors must also have plenty of time and physical strength, so that they can stand the test of spirit. For normal office workers, because the main energy is on the job, so even if they enter the stock market, they can only choose stocks with good stability to invest< In addition, new shareholders must learn certain knowledge before entering the market:
(1) economic knowledge. The stock market is an important part of the financial market. Therefore, investors must learn the necessary financial knowledge, have some knowledge about money, credit, interest rate, inflation, and understand some basic economic principles, enterprise financial accounting, marketing and other knowledge, which is concive to understanding and grasping the development direction of the stock market< (2) legal knowledge. Securities investment is a complex economic activity involving tens of millions of people, which involves many legal issues. Therefore, investors should understand and master relevant legal knowledge, such as civil law, securities law, company law, bankruptcy law, etc. We should also have a basic understanding of the regulations governing the stock market< (3) mathematical knowledge. To calculate the income and risk of government bonds, to forecast and analyze, all need relevant mathematical knowledge. If possible, you should also know how to use computers. There are many securities softwares in the market that can help you understand information and analyze market trends< At the same time, new market entrants should master certain skills:
(1) the skills of market analysis. Investors must learn to analyze the price change trend in the fluctuation of the securities market, and choose the right time to buy and sell. This includes learning to look at the quotation sheet of the securities market and understand some basic technical analysis methods< (2) trading skills. At present, many securities business departments adopt automatic entrustment of investors, which requires investors to be familiar with the proceres of automatic entrustment and improve the speed of inputting entrustment instructions, so as to better grasp various opportunities. In a word, the new investors should have spare money, spare power and certain knowledge and skills. People who do not have the above three conditions are generally not suitable for stock investment. When indivial investors start to invest in stocks, they almost have no investment common sense. The clear news dominates all investment directions. If they lose as soon as they buy, they will be blessed by their ancestors. In the future, you will only be a good resident who pays certificates and taxes; If you win as soon as you buy, the result of conceit is usually a big loss. How to minimize the loss and accumulate technology in the initial stage of investment has become the focus of this period. The following are my suggestions for new people in the stock market:
1. Read all kinds of stock investment and economic news every day, and pay more attention to the reports about stock knowledge. As for the analysis reports of indivial stocks, most of them are hearsay or outdated information, so they should not be used as the basis for buying stocks. In the daily unconscious absorption of knowledge, you have graally acquired the basic concept of value investment< However, investors should at least have the most basic market and proct concepts, and you must understand what the company is doing? What is the market evaluation of his procts? Who are the competitors? Where are the main customers? If possible, you can try to eat, try and play, and go to the front line to understand the competitiveness of procts. Growth investment is effective only after long-term observation. For retail investors, the simplest way is probably the most effective way
3. Observe the stock price changes of various companies on the Internet, daily, weekly and monthly trends, analyze the reasons for their rise, the relationship between stock price and trading volume, the relationship between stock price and news, and the relationship between stock price and margin trading.

Buffett's father is a stock broker. He instilled in him the correct investment concept when he was young. At the age of 13, he bought his first stock and got his first profit. There is no quick method for stock investment, and we can't rely on luck. We can't trust the cards, and we can't just listen to the news. If you want to make a profit from investment, you must first establish a correct investment concept, and then spend more time on research. The younger you are, the earlier you start to study, the better time will be for you. It's better to run into the sun than choose the day. No time is just an excuse. Make up your mind to start today.
therefore, new investors should have a good attitude before entering the market. First, don't be afraid of the stock market. The growth of the stock market in the world shows that the development of the stock market is concive to promoting social and economic development. In the long run, the trend of the stock market is also upward. China's securities market is becoming more and more perfect. As an emerging market, there is no doubt about the growth space and development prospect of China's stock market. Second, don't have unrealistic fantasies. An important reason why many people suffer losses in the stock market is that they have high expectations. In fact, although the stock market will rise and fall greatly in a period of time, from the basic trend, its rising speed is basically consistent with the country's economic growth. In this sense, it is difficult to achieve a rate of return that greatly exceeds the level of economic development. Moreover, there are always risks in the stock market. The stock price is changing rapidly. No one can accurately predict the changes of the market. It is almost impossible to win without losing. If the market participants do not have such psychological preparation, not to mention that they may lose money, even if they can make money, it is not worth worrying all day and having trouble sleeping and eating
after adjusting their mentality, new shareholders should also consider their own financial strength. If you have a rich income and a wealthy family, you can naturally invest part of your accumulated money in stocks. For the investors who are living in a tight life and have a heavy financial burden on their families, it's time to weigh up the gains and losses, and never borrow money to invest in stocks. Because different sources of funds tend to form different investment mentality. Generally speaking, the capital entering the stock market is your own surplus. Even if you are "trapped" in the stock market, you will not affect your life, so you can be more calm. If your money is borrowed, when the deadline is approaching, the performance of the stock market is often prone to irrational behavior, which often leads to chasing up and down
new entrants should also consider whether they have enough energy. Securities investment is a kind of intellectual behavior, so after China's accession to the WTO, it will make people worry and may be frustrated at any time. The profit and loss caused by the fluctuation of the stock market must constantly stimulate people's nerves and affect people's emotions. Therefore, investors must also have plenty of time and physical strength, so that they can stand the test of spirit. For normal office workers, because the main energy is on the job, so even if they enter the stock market, they can only choose stocks with good stability to invest< In addition, new shareholders must learn certain knowledge before entering the market:
(1) economic knowledge. The stock market is an important part of the financial market. Therefore, investors must learn the necessary financial knowledge, have some knowledge about money, credit, interest rate, inflation, and understand some basic economic principles, enterprise financial accounting, marketing and other knowledge, which is concive to understanding and grasping the development direction of the stock market< (2) legal knowledge. Securities investment is a complex economic activity involving tens of millions of people, which involves many legal issues. Therefore, investors should understand and master relevant legal knowledge, such as civil law, securities law, company law, bankruptcy law, etc. We should also have a basic understanding of the regulations governing the stock market< (3) mathematical knowledge. To calculate the income and risk of government bonds, to forecast and analyze, all need relevant mathematical knowledge. If possible, you should also know how to use computers. There are many securities softwares in the market that can help you understand information and analyze market trends< At the same time, new market entrants should master certain skills:
(1) the skills of market analysis. Investors must learn to analyze the price change trend in the fluctuation of the securities market, and choose the right time to buy and sell. This includes learning to look at the quotation sheet of the securities market and understand some basic technical analysis methods< (2) trading skills. At present, many securities business departments adopt automatic entrustment of investors, which requires investors to be familiar with the proceres of automatic entrustment and improve the speed of inputting entrustment instructions, so as to better grasp various opportunities. In a word, the new investors should have spare money, spare power and certain knowledge and skills. People who do not have the above three conditions are generally not suitable for stock investment. When indivial investors start to invest in stocks, they almost have no investment common sense. The clear news dominates all investment directions. If they lose as soon as they buy, they will be blessed by their ancestors. In the future, you will only be a good resident who pays certificates and taxes; If you win as soon as you buy, the result of conceit is usually a big loss. How to minimize the loss and accumulate technology in the initial stage of investment has become the focus of this period. The following are my suggestions for new people in the stock market:
1. Read all kinds of stock investment and economic news every day, and pay more attention to the reports about stock knowledge. As for the analysis reports of indivial stocks, most of them are hearsay or outdated information, so they should not be used as the basis for buying stocks. In the daily unconscious absorption of knowledge, you have graally acquired the basic concept of value investment< However, investors should at least have the most basic market and proct concepts, and you must understand what the company is doing? What is the market evaluation of his procts? Who are the competitors? Where are the main customers? If possible, you can try to eat, try and play, and go to the front line to understand the competitiveness of procts. Growth investment is effective only after long-term observation. For retail investors, the simplest way is probably the most effective way
3. Observe the stock price changes of various companies on the Internet, daily, weekly and monthly trends, analyze the reasons for their rise, the relationship between stock price and trading volume, the relationship between stock price and news, and the relationship between stock price and margin trading. The clearer the observation and analysis, the greater your chance of winning. Reverse investment is not just to say with your mouth and then to reverse at random. You must observe all kinds of possible changes for a long time before you can make a correct judgment
4. Analyze by yourself, tell others the analysis results, and ask them to tell you whether the stock is good or not. If the reaction is positive, try to buy one to practice your technique. There are risks in investment and financial management. Long term planning is the only way to rece risks. The Japanese stock god is Mr. kawawa yinzang's investment experience.
