I don't know if seniority is a culture, but it's really a science to find out about seniority. In China, the origin and history of generations are unknown to me. However, from the records in ancient books and my childhood experience, I feel that generations have changed and dynasties have changed. Generation, for a person, is decided at birth, and he has no choice. The seniority between the same clan is strictly observed. For example, the title must be accurate. In daily life, we should pay tribute to our elders, give up our seats, and pay great attention to seating, so as not to confuse the etiquette. A person's words and deeds and even his fate will be influenced by clan etiquette and bound by traditional morality. I have read such historical materials. There is a big village with more than 4,000 people under Wutai Mountain in Shanxi-Huaiyin Village. Zhao accounts for more than 90%, known as Zhao Village, with a prosperous population and ethnic groups. According to Records of Huaiyin Village, Huaiyin Village has been inhabited by human beings since the Neolithic Age. From the Hongwu year of Ming Dynasty, the ancestor of Zhao, Bo Yinggong, moved from Mayi, Shuozhou to Wutai and settled in Huaiyin. He gave priority to farming and thrifty housekeeping, and gradually became a noble family of five. The Zhao family has been bred for more than 600 years and passed down for 25 generations. It begins with diligence, generosity, and strict generation after generation. Also arranged and planned a set of 12 volumes of Zhao's Genealogy. The Zhao family's seniority is strictly observed. Even the white-haired old man must call the dolls older than himself grandpa and uncle. If someone calls the wrong name, they will be immediately accused and corrected by their people. The names of children in the clan are also based on the generations in the genealogy, and cannot be taken at will. It can be seen that people in Huaiyin Village have lived in this relatively closed or semi-closed environment for hundreds of years, and gradually formed and settled in a relatively independent culture and etiquette system, which has influenced generation after generation. There is little population movement here, people live a stable life and are relatively poor and backward. Self-sufficient natural economy inevitably requires the unity and cooperation of the same clan and the same family, helping each other, and the relationship between clans is relatively close, which is also closely related to the development and openness of social economy.
