Excuse me, did the son-in-law who was adopted by adoption in ancient times enter his ancestral grave or the woman's? Somebody give me a big advice.

hehe, two levels of consideration. First, it's usually buried in the wife's house. Second, the adoption of a son in law means that it is not prosperous to recruit a male son in law, so from the perspective of geomantic omen, the land of the woman's house is not very ideal, so after careful study, I mean that when the geomantic omen of both men and women is not ideal, find a place with better geomantic omen and bury it again.
