The Book of Changes talks about how a person’s fate is calculated

The "Book of Changes" is a book for divination, and the calculation of human life is from its first hexagram Qian, which shows a group of dragons without a leader, which is auspicious, to the sixty-fourth hexagram Weiji, which is good for drinking. No blame. Each hexagram represents an unknown destiny at a different time.

And each hexagram has a detailed explanation, and of course it is not just about fortune-telling. It is said that "the Yi Dao is broad and encompasses everything"~

The specific point is: first list yourself Look at the yin and yang attributes of the birth date and horoscope, and then add the remainder of the total number of strokes in your name divided by 8 to get your number~
