A person's palm depends on his left hand or his right hand.

Because the traditional Yin theory holds that men are mainly inherited by their fathers, so the left hand is dominant and women are inherited by their mothers, so the right hand represents women. This is because traditionally, the left side represents father and man, and the right side represents woman and mother. Five faces, the left represents the father and the right represents the mother. If the left eyebrow is high and the right eyebrow is low, then the father died from the mother. This statement is efficient!
