Why does every village have houses, priests and ancestors of Lao Yue? What's the name of this house?

This is called the ancestral hall, where every big family worships their ancestors. Generally, people will go to the ancestral temple to worship their ancestors when they get married, have children, enter the college entrance examination and enter high school. Usually, on holidays, the clansmen will collectively hold some sacrificial ceremonies to pray for the ancestors' peace and good weather, but this place is generally not allowed to go in and out casually.
