The first reason is that there is an old saying in China that no rules can make Fiona Fang. It is important to have national laws and family rules. And some noble families, with large populations, have children and grandchildren living together. The existence of family law is a deterrent, which can make the family have a better order, whether for better management of family affairs or for better promotion of family prosperity. This is the wisdom of the ancients.
The second reason is that China is a nation that emphasizes blood relationship. In ancient times, people with status and knowledge basically came from big families. A big family means that all people of the same clan live together, so it is very important to have a good order in a big family, that is, the existence of family rules.
The third reason is that ancient aristocratic families attached importance to clan inheritance, and family rules were also a kind of cultural inheritance. In ancient times, influenced by feudal thoughts, many intellectuals advocated Confucianism. Confucianism emphasizes benevolence, righteousness, propriety, wisdom and faith, which is highly respected by many intellectuals with status and prestige in ancient times. Therefore, these well-educated people, after having their own clan, will attach great importance to the inheritance of their family. Therefore, family rules should be used to better restrain the younger generation in the family. Only in this way can the family's good traditions be passed down and talents be cultivated slowly.
