Emperor Han Ming felt a little embarrassed, he heard Yihe say this, and knew that he had laughed too early just now.

Yihe said: "Your Majesty, if you want to understand the ten heavenly stem numbers, you must learn according to yin and yang!" Because they are arranged according to yin-yang. We just need to think of one, two, three, four, as the yin or yang side of six, seven, eight, and nine. In these ten digits, both zero and ten represent nothingness and consummation. One and nine are in a group. One represents the beginning of life, and nine represents the pole of life.

Two and eight are a group, two represents the yin and yang of life, and eight represents the yin and yang of the universe.

Three and seven are a group, three represents the power of life, and seven represents the fairness and justice of society.

Four and six are a group, four represents inheritance, and having children in the family is inheritance! Six represents prosperity. The fifth is the number of old yin, which symbolizes the girl, the mother, and the Bao Xi. ”

Emperor Ming of the Han Dynasty listened carefully to Yihe's words, for fear of making any more jokes.

Yihe conjured up an apple, looked at Emperor Han Ming and asked, "Your Majesty!" If you were to divide this apple with ten digits, how many portions do you think you can divide? ”

Emperor Han Ming said: "Well, I think you can divide as many shares as you want." ”
