There has been a record of "Qin customs forbidden" in Historical Records of Qin Shihuang. Moreover, people should keep their names secret not only after death, but also before death. This may be related to the prosperity of witchcraft in the name at that time. It is generally believed that by reciting the name of the enemy or writing someone's name, black witchcraft can be practiced and people will die. At first, taboo was practiced among the upper class and authorities, but later it became popular among the people, affecting every family and becoming a folk habit.
China people have the custom of respecting ancestors and ancestors, and ancestors and elders cannot be called by their first names. This taboo exists in the ancestor worship customs of Han, Oroqen, Ewenki, Kazak, Buyi and Tibetan. The Oroqen people think that calling their ancestors by their first names is disrespectful to their ancestors, and they are afraid of offending them and bringing disaster to future generations. I dare not call my elders by their first names, or even tell others their names.
Otherwise, I don't think there will be children with joints at home. If there is something with the same name as the elder, you should change the name of the object and change the statement. Otherwise, we will die young. No matter what Han people say or write, they dare not mention the names of their ancestors and elders. When Sima Qian wrote Historical Records, his father's surname was Tan, so he changed "Zhao Tan" to "Zhao Tong" and "Li Tan" to "Li Tong". In the Six Dynasties, in order to avoid the word "tung", someone renamed the plane tree "white iron tree". In the Qing Dynasty, Liu Wencuo never listened to Yue again because of his father's name. It can be seen that the family taboos in previous dynasties were strict. Until now, children are still forbidden to call their elders by their first names, let alone their birth names, and words with the same or homophonic names are also taboo. Especially taboo is the name of the younger generation.
