This is a magical way to measure a person's fate. Its method is to correspond the year, month, day and hour of a person's birth with heavenly stems and earthly branches, so that only eight words are needed to describe a person's birth.

This is a kind of fortune-telling that transforms a person's birth time into a trunk, and then brings it into the trunk to perform complex operations (this operation is not "addition, subtraction, multiplication and division" that we often use, but "birth control"). The eight-character method is still the most popular way of life in Chinese mainland.
