Was it male left and female right when buried? What if it's not?

If monogamy, after death, according to the ancient etiquette, men are generally left and women are right. If this is not the case, it is nothing. It's like changing seats when you are alive.

If there is polygamy, there are two arrangements:

Sandwich arrangement; That is, the husband is in the middle, the original is left, the latter is right, the third is left, and the fourth is right.

Arranged along the coffin; Husband ranks first, the original match is on the right, followed by the original match, the third is on the right, and the fourth is on the right, in turn.
