How did the eight-character fortune-telling method come about?

Eight-character fortune telling is to summarize the law of human survival in the natural environment. According to the date of birth of heavenly stems and earthly branches's Five Elements, the ups and downs of Yin and Yang, and the changes of birth and grams with the Universiade and fleeting time, we can infer a person's fate. The universe gives the earth gas and essence all the time. A person's fate can be dominated by the nature of the universe at the moment when his parents' sperm and eggs are born. The eight-character fortune-telling theory originated in the Spring and Autumn Period (Confucius said: life and death are determined by fate, and wealth is in the sky; If you don't know your life, you don't think you are a gentleman. ) developed in the Han Dynasty (Wang Chong in the Eastern Han Dynasty said in Lun Heng: People are born with qi and grow with qi. Expensive is expensive, and getting * * is expensive. In the three volumes of Li Zhuan's "Letters from Li's Life" in the Tang Dynasty, Han Yu said the deepest in his epitaph: "The five elements are based on the year, month, day and the day when people started. Prosperity leads to decline, and decline leads to death." Li's letter has only three pillars, and the year, month and day are used to push good or bad luck. In Song Dynasty, Xu Sheng wrote Yuan Hai Zi Ping, inferring a person's birth and death, good or bad future according to the date of birth. It is the first systematic and theoretical work in the history of eight-character fortune telling, which officially opened the eight-character fortune telling method. In the Ming Dynasty, Wan Mingying perfected the eight-character fortune-telling on the basis of predecessors, compiled twelve volumes of Three Commandments, picked out the essence from them, corrected paranoid views, and made a completely flexible argument. Since the middle of the Ming Dynasty, people who talk about stars and destiny have taken the "Three Destinies Meeting" as the confluence. In the past twenty years, fortune-telling has made new progress, and many forecasting masters have emerged, all of whom have a set of ground-breaking theories. Since ancient times, medicine, divination, astrology and physiognomy are one family, and "medicine" and "Yi" are the same principle. A skilled doctor of traditional Chinese medicine wrote a case of pulse diagnosis for patients, which is a medical academic paper. Pulse-following case treatment can cure people's diseases. An expert astrologer, he approved a numerology table, that is, a numerology academic paper. According to the numerology table, he seized the opportunity, pursued the success of his career, predicted good or bad luck, and ensured the prosperity of his career. Therefore, doctors and prophets are messengers to save lives.
