What is the function of the ancestral hall?

Sacrifice to ancestors.

The ancestral hall is a place where tribesmen worship their ancestors or sages. Ancestral halls have many uses. In addition to worshiping ancestors, these spacious ancestral halls will also be used as a place for activities when the grandchildren of each house handle weddings, funerals, birthdays, celebrations, etc. Clan relatives sometimes discuss important matters within the clan in the ancestral hall.

In addition, the ancestral hall is also the place where the clan leader exercises clan power. Anyone who violates clan rules will be educated and dealt with here, or even expelled from the ancestral hall. Therefore, it can also be a moral court in the feudal era.
