There is a saying in China that the habit of “male left female right” is related to Fuxi and Nuwa, the ancestors of the legendary human being.
It is said that after Pangu opened the earth in the past, his body was turned into everything in the heavens and the earth, in which his left eye was turned into the sun god, that is, Fuxi; the right eye turned into the moon god, that is, the son-in-law.
Fuxi is on the left and the son-in-law is on the right. The son-in-law creates the human being with the loess, which is the ancestor of mankind and the symbol of ancient motherhood.
Since people respect the son-in-law, they also advocate the right, so the right side represents a higher status. Therefore, the habit of “male left female right” has been formed.
