During the Spring and Autumn Period, Qi assisted for forty years and became one of the five tyrants in the Spring and Autumn Period. However, he also has a considerable relationship with businessmen. Guan Zhong was born in a poor family. When he was a teenager, he did business with his good friend Bao. When he gets a bonus, he often gets twice as much money. When someone was dissatisfied, Bao defended him: Guan Zhong was not greedy, but because his family was poor, I volunteered to let him. Guan Zhong almost shot the owner of the bag with an arrow. Qi Huangong wanted to kill him when he came to power. Bao defended him: Guan Zhong is a genius in the world. You use him, he will shoot the world for you. So he can be reused. Later generations often say that Guan Bao's friendship is this allusion. Because Guan Zhong is a businessman with rich knowledge of commodity production, currency and trade, he fully affirmed the position of businessmen in society after he took power. For the first time in the history of China, people were divided into social groups according to their occupations. Since then, all dynasties in China have basically accepted this typical occupational division-scholars, farmers and businessmen. Guan Zhong implements the state policy of controlling commerce, and the number of four people is stipulated in proportion. In foreign trade, he adopted a policy of encouraging development. Because Qi is close to the sea and rich in fishing salt, Guan Zhong practiced Qi fishing salt in Donglai, which made the steward sneer at it and thought it was beneficial to the princes and himself. The era in which Guan Zhong lived was an era of "ritual collapse and bad music" and rapid social changes in the history of China. After several personnel changes, Guan Zhong was finally recommended by Bao and was named Qing, honoring him as "Guan Zhong". Guan Zhong was in power for forty years, and he carried out drastic reforms, and made fruitful reforms in military affairs, politics, taxation, salt and iron, which made Qi's national strength prosperous. He helped Qi Huangong with the slogans of "respecting the king and rejecting foreign countries" and "uniting the vassals and conquering the world", making Qi the first big country to dominate in the Spring and Autumn Period. Guan Zhong's thoughts and talents are embodied in Guan Zi.

There are eighty-six articles in Guanzi, ten articles are lost, and seventy-six articles are saved. Later generations thought that it was not written by one person, and it had the characters of Warring States, Qin and Han Dynasties, and contained some ideas and theories of Guanzhong School. Its content is extensive and profound, mainly based on the thoughts of legalists and Taoists, as well as the thoughts of Confucianism, strategists, strategists, peasants and yin and yang scholars, and also involves astronomy, ethics, geography, education and other issues. Among the pre-Qin philosophers, "Xiang is far from his book." It can be said that Guanzi is the biggest miscellaneous work in the pre-Qin period. When Zhuge Liang lived in seclusion in Nanyang Longzhong, he often compared himself to wind music. "Guan" is the name of Guan Zhong and Qi; "Le" is a famous name of Le Yi, the state of Yan. They all helped the monarch to establish outstanding feats. Guan zhong (? -645 BC), whose real name is Yi Wu, whose middle name is Ming Jing, also known as Yingshang, Anhui, was a famous politician and philosopher of Qi in the early Spring and Autumn Period. He assisted Qi Huangong (Xiaobai) of the State of Qi, made a comprehensive reform of domestic and foreign policies, and formulated a series of policies and strategies to enrich the people. He collected taxes reasonably to reduce the burden on farmers in order to realize "people's wealth" and "people's security"; Improve the state management system, develop civilian armed forces, and unify military and political leadership; Use national strength to develop salt and iron industry and increase fiscal revenue; Take the diplomatic strategy of "respecting the king and rejecting foreign countries" and take the initiative in diplomacy. He reigned for three years and ruled the country together, becoming the "head of the five tyrants". Guan Zhong's achievements are not only related to his own talents, but also related to his ability to know people and selflessly recommend talents. Guan Zhong and Bao were friends when they were young. When they did business together and distributed profits, Guan Zhong privately took away twice as much property as Bao. Others are unfair, Bao said. This is not because he is greedy for money, but because his family is poor. The two men led the troops to fight, took the lead, and personally took the arrow stone, but they rushed in the back and retreated in front. Others said that Bao said that it was not because he was afraid of death, but because he had an old mother at home. Bao's spirit of tolerating others deeply touched Guan Zhong. He said, "My parents gave birth to me, but the steamed stuffed bun knows me". Later, Bao overcame many difficulties and introduced Guan Zhong to build an altar to worship, but he was willing to come second. Sima Qian said with emotion: what the world values is not Guan Zhong, a saint, but his ability to know people by writing. Guan Zhong's achievements are closely related to Qi Huangong's generosity, knowing people well and employing people without doubt. Guan Zhong originally helped Xiaobai's brother and son to correct it. It is futile to correct and strive for a position. Guan Zhong once shot an arrow at Xiao Bai, and Xiao Bai had to take off before he faked his death. Later, after Zi Zheng died, Xiao Bai became the head of State of Qi. He respected corporal xian, let bygones be bygones, accepted Bao's recommendation, and resolutely sealed Guan Zhong. When Qi Huangong personally went to the suburbs to meet Guan Zhong, when they entered the city in the same car, "people were shocked". Later, someone slandered Guan Zhong, but Qi Huangong didn't believe it and retorted. He also trusted Guan Zhong more, honoring him as "Guan Zhong", and made it clear that "major national policies should be brought before me, implemented to a certain extent, and governed by Guan Zhong". In this way, Guan Zhong can display his intelligence and achieve something.

Guan Zhong's health care thoughts mainly include: (1) He thinks that "the life of mortals must be based on fairness", that is, "fairness" is used for health care, including optimism and correctness, avoiding two evils in five quarters and being superior to others; ⑵ Advocate quietness and happiness, and nourish the soul. I believe that only "if you want to go and announce it, you will be quiet when you announce it;" Static is fine, fine is independent; If you are alone, you will understand. If you understand, you are God. "(3) think that" quiet is better than impatience ","quiet is what you get, impatience is what you lose. " (4) advocate "a sense of security for the old", if "a sense of security for the old, sleepy and tired". That is, if the elderly don't think often, they will soon become dull and promote aging. Life itself is a rhythmic form of material movement, and the rhythm of life that each of us must follow is the reflection of this rhythm. As early as more than 2,000 years ago, China has regarded daily life as an important way of health care and longevity. For example, Guan Zhong in the Spring and Autumn Period once said, "When people are alive, they should benefit from eating and drinking. Eating and drinking is good for health and life. "The ancients said that depression not only refers to the time of work and rest, but also refers to all daily activities including clothing, housing, work and rest. To embody the benefits of health preservation in our life, it is important to see whether we can arrange our life according to the laws of nature and the rhythm of the human body itself, which requires establishing a reasonable living system, living a suitable life and paying attention to ordinary daily life. To formulate a reasonable living system, we should not only adapt to the characteristics of the four seasons' climate and the law of daily changes in the morning and evening, but also make it suitable for people according to their age, physique, region, work, habits and conditions. For example, the essence of old age is declining. Therefore, it is pointed out in Qin Shou's New Book on Pension that the "banquet of walking, living, sitting and sleeping" for the elderly must be skillfully established, and it is not necessary to be wide and long, and it will stumble if it is long, and it will stumble if it is wide. In addition, there are some special living systems, such as rest, bathing and washing, which are also health care experiences with scientific value. Sun Simiao said, "If you work hard, you can't cure all diseases. "He himself is an example of insisting on labor and practicing. He made a regular life system for himself, often engaged in manual labor such as collecting and planting medicines, often climbing mountains and steep cliffs, and traveled all over his hometown, famous mountains and rivers and wilderness. The collection seasons and methods of 233 kinds of medicinal materials listed in Qian Jin Fang are the embodiment of his hard work. Arrange a suitable living environment. First, adapt to the environment, such as adjusting indoor temperature and humidity, and increasing or decreasing clothes and bedding in time. Second, the creation of the environment, such as planting flowers and trees, can adjust the air and make people feel happy; Relaxed and lively music can make people feel happy and harmonize qi and blood. Creating a clean and beautiful residence is a necessary condition for health and longevity. In addition, we should pay attention to the choice of air conditioning environment. The ancients said, "Quiet people live long, noisy people live long". The longevity of the elderly in mountainous areas is not only related to the fresh air, but also to the tranquility of the environment. All kinds of noise have serious damage to human health and life. Therefore, insisting on outdoor activities and taking part in outdoor tourism are all important ways to breathe fresh air and promote health. As the "Chu's suicide note" said: "The sound of running water can nourish the eyes, reading can nourish the heart, playing the piano to learn Chinese characters can nourish the fingers, walking with an idle stick can nourish the feet, and sitting and breathing can nourish the bones. "General daily life taboos include labor taboos, sex taboos, sleep taboos and so on. In the Song Dynasty, Pu Gan-guan approved in Health Care Records: "People who keep in good health should work less and be exhausted. Therefore, the water flow is clear and stagnant. People who want to keep fit, like flowing water, don't want to sit tired, don't want to be tired, but slow down, that is, the ability of small labor. "The' strain' mentioned by Chinese medicine refers to the damage caused by inappropriate activities and excessive fatigue." Su Wen "Xuanming Five Qi Articles" said: "Five pains, long-term blood injury, long-term gas injury, long-term meat injury, long-term bone injury, long-term muscle injury. "Atrioventricular overwork is an important cause of disease and aging. Abstinence is the consistent proposition of TCM health preservation. For example, "The Secret Book of Immortality" says: "Internal work is wisdom and external work is physique, which are enough to know how to fold, but housework is more serious, because its form and spirit are used together, and both essence and spirit are hurt. "Therefore, Lao Tzu advocates' holding on to the benefits', and Qu Li emphasizes' not wanting to hang down'. The taboo of sexual intercourse in Thousands of Women and Wings is "fatigue, drunkenness, happiness and sadness, and fever between men and women." In the story of Spring and Autumn Annals, the number of times you enter the house is "the new strong swims in the house for ten days, the middle-aged new strong, the middle-aged early declining, the middle-aged early declining, the big declining in the month, when the new strong. "The abstinence method introduced in" The Life of the Elixir of Life "is:" When you want to be passionate, you will be cold at the thought of getting sick. "
