Why is it said that "father and son sit at different tables, uncles and nephews drink at different tables"? What's going on?

Chinese culture is extensive and profound, and its thousands of years of history and culture can still shine brightly today, influencing generations of people. Traditional culture can be divided into essence and dross. China’s excellent traditional culture is the soul of Chinese culture. Common sayings are also a kind of traditional culture. There is a saying called "Father and son sit at different tables, uncle and nephew don't drink at the same table". Why is it said like this?

First of all, on the surface, this sentence means that fathers and children should not eat at the same table, and uncles and nephews should not drink happily at the dinner table. Many people will think that this sentence is rubbish, does not make sense, and is nonsense. If we take it at face value, this sentence is outdated today. Today, it is very common for fathers and sons, uncles and nephews to sit at the same table. ?Father and son sit at different tables, uncle and nephew don't drink at the same table? It is natural for everyone to criticize them.

I think this sentence has an extended meaning: filial piety and respect. Ancient China has always advocated filial piety. There are three types of unfilial piety, and the worst is not having children. What we are talking about today is: "The tree wants to be quiet but the wind does not stop; the child wants to be nourished but cannot be kissed". Respect and filial piety to parents are traditional virtues of the Chinese nation, which we have always promoted. The same is true for uncles and nephews. The uncle is an elder to the nephew. Respecting them is what a junior should do. "Father and son sit at different tables, uncle and nephew don't drink at the same table", more describes the relationship between father and son, uncle and nephew of the older generation.

Under the new environment, the relationship between father and son has also undergone great changes. Nowadays, many fathers and sons get along more like friends. Whatever happened to his son at school, he was happy to come back and share it with his father. The two of them were very harmonious watching movies and football matches together. I think this is also a new identity model for father and son to get along with each other outside of this identity. The traditional relationship between father and son may be a little reserved and unnatural.
