There is no son at home, only a woman moves the grave. What's the point?

The burial date of the old man is not chosen by whether there are children or not, and it has nothing to do with whether there are children. It was placed on the bed of the funeral home, not on the ground. That is to say, although they have been dead for three years, they are still not buried, and their souls can move at any time without being buried. The date of burial is the date when the deceased belonged to the same family. For example, if the deceased is a horse, the date of burial is used, that is, the date of sheep, and if it is a mouse, the date of burial is used, that is, the date of burial of cattle.
