Fortune telling is a common name among the people. The academic title is prediction, and the academic study of fortune telling is called Yi Xue, also called Shu Shu. The core of this theory is the branches of Yin-Yang and Five Elements and the Eight Diagrams Yijing, and the theoretical system is complex and profound. Fortune-telling in a narrow sense is a prediction of the date of birth, while fortune-telling in a broad sense includes reading numbers, palm reading, eight diagrams and six hexagrams, Taoism, geography, geomancy and so on. Ancient divination and divination belong to fortune telling. Fortune-telling, China's prediction has a long history, and its origin can be traced back to Fu, the highest city. Then Zhou Wenwang played gossip, and fortune-telling began to improve gradually.

The eight characters, also called four pillars, are heavenly stems and earthly branches's eight characters found in the calendar, which represent the year, month, day and time of a person's birth with the heavenly stems and earthly branches of heaven and earth. It adds up to eight words. Eight-character (eight-character numerology, eight-character numerology) is a method to infer fate according to eight characters. Wu Tao, a teacher at Beijing Institute of Yi Studies: The main concept of eight-character fortune telling is fate, or the game of life. In short, when a person is born, the arrangement and combination of heavenly stems and earthly branches (that is, eight characters) is fate. But it's impossible to work out the good or bad luck with only eight heavenly stems and earthly branches. Therefore, heavenly stems and earthly branches has the attributes of yin and yang and five elements, and has the relationship of mutual development and mutual restriction. And derived from punishment, impulse, injury, combination and other relationships. In addition, combined with the four seasons and five directions, it is sunny day and night to piece together a fortune-telling system. The relationship between life and punishment is also called positive printing and partial printing, which hurts officials, eats gods, favors officials, is rich and partial, and is on a par with others, robbing money, and is collectively called "Ten Gods". Another important concept of horoscope fortune telling is luck. Fortune-telling focuses on relatively stable life contents such as the rich and the poor, while fortune-telling focuses on dynamic life problems such as good fortune and bad fortune, which is usually called fate. Luck includes great luck, small luck and fleeting time. Generally speaking, luck begins with birthdays, and boys and girls are born in the year of the sun and the year of the moon, combining solar terms and months. Time flies, also known as Tai Sui, is calculated according to the stem and branches of every year after birth. Besides life and luck, there are some concepts, such as evil spirit, Yin Na's five elements, fetus and the palace of life. The so-called evil is to fix some combinations between certain branches into formats, and once these formats appear in people's eight characters, they are called some evil. God is a symbol of good luck, but evil spirits are a symbol of bad luck. For example, Ji Shen's "Wenchang Guiren" is smart and elegant; The fierce "yin-yang fault" made the main marriage not smooth. Because the names of some evil spirits sound mysterious, they are often used by charlatans to scare people and cheat money. In front of the fortune-telling booth, people often report the date of birth, and fortune-tellers will tell them that life is gold or wood, which involves Yin Na's five elements. Early numerology only used five elements, and Yin Na was an ancient phonology introduced later, and its foundation was also five elements. Fetal element refers to the month when a person is pregnant, and life palace refers to the place where life lives. Eight-character fortune-telling is based on the above concepts, mainly based on the relationship between the sun Lord and the four pillars and branches, combined with the restraint of the Universiade and the fleeting branch, and referring to the situation of the Universiade, evil spirits, happiness, pregnancy and life palace, to infer various situations of life.
