I don’t know if seniority is a culture, but understanding seniority is really a science. In China, the origin and history of seniority cannot be verified by me, who is not very talented and knowledgeable. However, the records in ancient books and my own experience from childhood to the present have allowed me to touch the river of subtle changes in seniority through the vicissitudes of time and the changes of dynasties. Seniority, for a person, is determined when he is born, and he has no choice. The seniority among members of the same clan is strictly observed. For example, the names must be accurate. In daily life, one must greet the elders, offer smoke, give up seats, and give way. The order of sitting is also very particular, and etiquette must not be messed up. A person's words, deeds, and even destiny will be affected by clan etiquette and bound by traditional morality. I have read historical data like this: In Shanxi, at the foot of Wutai Mountain, there is a large village of more than 4,000 people - Huaiyin Village. The surname Zhao accounts for more than 90%, and people in the village are called the Zhao family, with prosperous people and a prosperous family. According to "Huaiyin Village Chronicles": Huaiyin Village has been inhabited by humans since the Neolithic Age. Beginning in the Hongwu Year of the Ming Dynasty, Boying Gong, the ancestor of the Zhao family, moved to Wutai from Mayi, Shuozhou, and settled in Huaiyin. He mainly engaged in farming, was diligent and thrifty, and gradually became a prominent family in Wutai. The Zhao family has been multiplying for more than 600 years and has been passed down for 25 generations. They started hard, treated others generously, passed on the family tree, and were strict in seniority. They also organized and planned a set of 12 books called "Zhao Family Genealogy". Seniority is strictly observed in the Zhao family. Even the old man with white hair must call the children who are older than him as grandpa or uncle. If someone calls someone by the wrong name, they will be immediately criticized and corrected by the clan members. The naming of children in the clan is also based on the seniority in the genealogy and should not be chosen arbitrarily. It can be seen that the people of Huaiyin Village have lived in such a relatively closed or semi-closed environment for hundreds of years, and have gradually formed and settled a relatively independent culture and etiquette system, which has influenced one generation after another. a generation. There is little population movement here, people live a stable life, and their lives are relatively poor and backward. The self-sufficient natural economy inevitably requires the unity and cooperation of the same clan and family, helping each other, and the ties between clans are relatively close, which is closely related to the development of social economy and opening up. The degree is also closely related.
