What far-reaching influence does patriarchal clan system have on our society?

1) has the phenomena of "respecting ancestors" and "confessing ancestors to the clan", which has formed the traditional virtues of the Chinese nation such as "filial piety first" and "not forgetting clan".

Negative effects:

1) the idea of carrying on the family line and giving preference to boys.

2) obvious interception and differentiation between different surnames and different clans.

3) Form a style of cronyism and obedience.

There are also some social systems, such as the tenure system for cadres.

That's about it. You can also discuss it with your classmates. I'm here for reference only.
