According to the theory of five elements, everything in the world is composed of five elements: gold, wood, water, fire and earth, which have different forms of expression in different things. For example, five colors: green, red, yellow, white and black; Five tones: horn, emblem, palace, business and feather; Five flavors: sour, bitter, sweet, spicy and salty; Five internal organs: liver, heart, spleen, lung and kidney; Five emotions: joy, joy, lust, anger and sadness; P5: Benevolence, courtesy, faithfulness, righteousness, wisdom, etc. The five contents of everything show the five elements of wood, fire, earth, gold and water respectively. The five elements have the order of generation, mutual generation and mutual control. Produce wood, fire, earth, gold and water; The order of mutual growth is: wood fire, fire born soil, native gold, gold born water, aquatic wood; The order of mutual recognition is: water can overcome fire, fire can overcome gold, Jin Kemu, Muketu and Tuke water. The combination of Yin-Yang and Five Elements Theory became the theory of ancient people to explain various natural and life phenomena. 2 Gossip Theory The gossip theory holds that in ancient times, Tai Chi gave birth to two instruments, two instruments gave birth to four images, and four images gave birth to gossip. Tai Chi is a period when Yin and Yang are inseparable and heaven and earth are chaotic. The' two instruments' are heaven and earth, such as the yin and yang fish in the' eight diagrams' soil, the white fish is yang and the snakehead is yin. The ancients compared yin-yang fish to the sun, the moon and the earth. The sun is yang, the moon is yin, the earth is yin, and yin and yang surround each other, indicating the intercourse of yin and yang. The ancients used four images to symbolize the four directions and the four seasons of the year. Gossip can be divided into "gossip about celestial bodies" and "gossip about human bodies". The human body is a system with complex structure and functions. The meaning of' human body gossip' is to reflect the body image of human body and the application of gossip in human body diagnosis. The most important thing here is the concept of harmony between man and nature. There are not only Tai Chi Yin and Yang holograms in the human body, but also' Eight Diagrams' holograms. The human body is a gossip, and every part is covered with small gossip holograms. No matter the eyes, umbilicus, ears, hands, feet, abdomen, tongue and pulse, there are eight diagrams holograms, which can be oriented through eight diagrams. Through' gossip', it embodies the relevance and integrity of the human body. The human body is also a big Tai Chi, and there are small Tai Chi in all parts. There are two taiji instruments in the brain, five internal organs and six internal organs. The human body is a large combination of yin and yang, and other parts are small combinations. The Eight Diagrams of Human Body Operation embodies the unified whole formed by man and the universe. Man's survival can not be separated from the natural environment endowed by the universe, and the movement changes between the universes are reflected in the human body. The universe and human body have mutual induction in their respective movements, which embodies the principle that heaven and man are integrated and medicine is easy to communicate through gossip. The 20-layer content of the whole map links the movement law of celestial bodies with the operation and changes of seven meridians and eight veins, meridians and acupoints, and diet health of the human body, forming a system of harmony between man and nature. This picture shows the exciting time and natural images of the twelve meridians, which is of practical value for guiding fitness, disease treatment and rehabilitation exercise, as well as for the research of time medicine, Yi medicine and top measurement medicine. The word "magic" originated from Zhuangzi Tianxiapian (see Zhuangzi Tianxiapian), which has the same meaning as "magic" and "magic", and some Taoist priests also call it "magic". Taoism has done a lot of Taoism, such as divination, character sealing, praying for blessings, forbidding spells, inner elixir, outer elixir, yellow and white fire, crossing the valley, walking, room, fairy medicine, convincing and so on. Ma Song Duan Lin once briefly introduced Taoism in the literature examination. He said: "Gai Jingqing said; Refine and improve; Say it again with food; Fu Zhuan said it again and again; Classical science and education is another story. "He said that the book of Huang Lao Liezhuang is pure and inaction, but slightly refined; Red pine nuts and Wei Boyang only talk about cultivation but not purity; Lu Sheng, Tao Shaojun and Luan Dayan brought meals without training; Zhang Daoling and Guan Qian's words are symbolic, not refined and borrowed; Du Guangting said only classic science and education below. There are many Taoist techniques, which can be roughly divided into five categories, and the five Taoist techniques can be roughly explained as follows: First, the so-called "mountain" is a kind of knowledge that cultivates "body" and "spirit" by feeding bait, building foundations, metaphysics, boxing and spells, so as to achieve physical and mental fullness. Bait-is a method of using tonic, wine and daily diet to enhance physical strength and treat diseases. Tsukiji-a method of using meditation and meditation to control the mind, qi and spirit, so as to enhance physical strength. Xuan Dian is a method of cultivating the mind and nourishing the nature based on Lao Zi and Zhuang Zi's thoughts. Boxing-is a way to keep fit by practicing various martial arts. Spell-a kind of psychic self-cultivation spell, whose main function is to ward off evil spirits, suppress evil spirits, and seek good fortune to avoid evil. In a word, "mountain" is a kind of knowledge to cultivate perfect personality by meditation, cultivation, martial arts, diet and other methods. Second, the so-called "medicine" is a method of using prescription, acupuncture and psychotherapy to preserve health and treat diseases. Prescription-a prescription for treating diseases and practicing by making various drugs into powders and pills. Acupuncture-Acupuncture and moxibustion, collectively referred to as acupuncture, is a folk prescription to treat diseases by stimulating the affected parts according to the principle of human meridian and qi and blood circulation. Psychotherapy-a good way to treat human diseases by mastering people's mind (psychological state). Now it is called "psychotherapy". In short, "medicine" is a method to treat human diseases through prescription, acupuncture, psychotherapy and other means. Third, the so-called "destiny" of life is a kind of knowledge to understand life, reach the laws of nature and improve human life by reasoning about fate. The main works used to push fate are Wei Zi Dou Shu, Zi Ping Push Fate, and Xing Ping Hui Hai. Its way is based on the time of birth and the five elements of yin and yang. In short, "fate" is to infer people's fate, and then to achieve the knowledge of seeking good fortune and avoiding evil, thus improving the needs of human development. Four, the so-called "phase", generally including "seal phase, name phase, human phase, family phase, tomb phase (feng shui)" five, in order to observe a magical method that exists in the phenomenon world. Seal-it is to look at the seal of others to decide fate. Printed in China, it used to be a certificate of power. Fame and fortune-it is a method to infer the development of good or bad luck through five paragraphs, combined with numerology, employing names or store names. Human physiognomy can be divided into two categories: physiognomy and palmistry. By observing the lines and colors of the face and hands, we found a way to know the good and bad luck and pathology of people. Home image-that is, the geomantic omen of Yangzhai-is a magical method to observe its pattern and analyze and infer the good or bad luck of human habitation. Tomography (geomantic omen)-that is, a ghost house-is a magical way to bury ancestors by choosing a place to hide their descendants. In short, "phase" is a way to observe the objects seen by the eyes in order to achieve the purpose of seeking good fortune and avoiding evil. Five, the so-called "divination", including divination, auspicious choice and divination, aims to predict and deal with things, in which the types of divination can be divided into "fragile" and "six gods". Divination-the so-called divination is based on the Book of Changes, combined with the mutual constraints of heaven, man and earth, to infer good or bad luck. Lucky Day-The main works, represented by Taoist magic, deal with unlucky factors through the combination of layout, fighting and magic, which are mainly used in ancient military affairs. Bureau measurement-the main work, represented by the number of gods, is a mathematical method to calculate the country's political destiny, fortune and historical change law through the twelve divinatory symbols. Inner alchemy, health preservation, martial arts and Taoism have many names in ancient times, such as cultivation, cultivation, self-cultivation, health preservation, hygiene and longevity. Just a few examples. Now it is generally called "cultivation", "practice" or "health preservation". The meaning of practice is to cultivate temperament and refine life. Sex refers to the spirit, and life refers to the body. Self-cultivation means self-control of the mind and body through certain ways and methods, so as to achieve the lofty goal of "my life is up to me". "
