The woman must be a pillar to eat and hurt, and the man must be an official to kill.

In real life, most people have one child, but very few have twins, some have male twins, some have female twins and some have twins. In addition to yin and yang feng shui, twins have a special performance in the eight-character numerology.

In the eight characters, a woman suffers from food injury, and if she exposes two injured officials, she will give birth to a pair of male twins. Exposing two food gods in the sky will give birth to a pair of female twins. The man in the column is injured by food, and the two injured officials are exposed to the sky, which will give birth to a pair of female twins; Male officials kill the king in the column, and Erqi kills the heavenly stems, which will give birth to a pair of male twins. Women who give birth to twins have mixed food and injuries in the column; The man who gave birth to twins was mixed in the official killing. When they gave birth to twins, most of them were Zhu Ji, who liked to use the Year of God. A child will also be born in a year when God is taboo or weak.

In practice, we can see that a couple who give birth to twins, especially a couple who give birth to male twins, the female side will eat the pillars and the male side will kill the strong, which shows the magic of nature and the efficacy of eight-character numerology.
