Fortune telling usually refers to eight-character fortune telling or four-column prediction. Luo Lihua, a master of Yi-ology, said: This is China's traditional method to predict the changing law of life movement. Astrologers arrange the year, month, day and time of a person's birth into eight characters (called "eight characters") according to heavenly stems and earthly branches, and then use the five elements of this branch to calculate a person's fate. It is a way to use personal information to predict or judge the fate, such as the lines of face and hands, the eight characters of birth, the strokes of names and so on. A learned fortune teller linked fortune-telling with the Book of Changes, one of the five classics. In fact, the Book of Changes itself is regarded by some people as the earliest book of divination, but these books are often difficult to pass scientific research, so some people think it belongs to superstition and the like.
