Why should people recognize their ancestors and return to their ancestors?

This is the most normal thing, and it is also the most common thing for all people in China. There is no need to ask questions. The ancestors of our Chinese nation are China people, and we are all descendants of China people, so we will pay a public sacrifice to the people of China at the national level. Every big family also sacrifices to their ancestors every year. After the rapid flow of population and the one-child policy, some parents paid little attention to this family tree, which led some people to be unfamiliar with it and not understand it at all. So there may be a question to ask.
