One of divination, four-column speculative divination

Four-pillar divination is also called eight-character divination, and the main concept is fate, or fate. In short, when a person is born, the arrangement and combination of heavenly stems and earthly branches (that is, eight characters) is fate. However, it is impossible to calculate good or bad luck with only eight 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, it also combines four seasons and five directions, sunshine day and night and other factors to piece together a set of divination 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 plunders wealth, and is collectively called "Ten Gods".

Another important concept of horoscope divination is luck. Life focuses on relatively stable life contents such as wealth and fortune, while luck focuses on dynamic life problems such as good or bad luck, 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 divination pavilion, people usually report the date of birth, and the diviner will tell the seeker whether his life is gold or wood, which involves Yin Na's five elements. The early numerology only used five elements, and Yin Na was an ancient phonology introduced later, based on 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 divination 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, music, pregnancy and life palace, to infer various situations of life.
