First, in order to avoid killing multiple surnames into single surnames.

For example, Shangguan Shi originated in Henan. Because of the war and natural disasters, ancestors moved to Shaanxi and set up aristocratic families in Gansu, Shaanxi. Shangguan's compound surname, especially in the Han Dynasty, produced the most celebrities, including General Shangguan Jie.

This man won the trust of Emperor Wu of the Han Dynasty and was entrusted with an important task, and he was an assistant minister with Huo Guangtong. Later, because of the power struggle with Huo Guang, it ended in failure and was finally blacked out. Wildfire never completely engulfed them. Of course, some people in Shangguan Shi escaped. In order to avoid Huo Guang's pursuit, they changed their surnames to "Guan".

Second, the evolution of the times has simplified surnames.

The youngest son of Yue State is the ancestor of Ouyang family. Because his fief is in the south of Ouyue in Wucheng, it is called "Oushan" for short and "Yang" in the south, so his descendants take "Ouyang" as their surname.

Because of the evolution of the times, it was gradually simplified into "Ou" and "Yang" surnames, and later some children with "Ou" surnames were changed to "District" surnames. It can be said that the ancestors of these three surnames and "Ouyang" surnames are the same person, that is, the sons without borders.

The Origin of China's Surname:

The original source of China's surname is primitive religious worship, totem worship and ancestor worship based on "Heaven". The so-called "heaven" is the law that everything has. There are three views on totem in academic circles: totem name is the same name of a group; Totem is the ancestor of the group, and all members are multiplied by totem; Totem is the patron saint of the group. ?

The origin of surnames can be traced back to the matriarchal clan system in primitive human society, so many ancient surnames in China are beside or at the bottom of female characters. Surname is a specific symbol to distinguish clans, such as the name of a tribe or the name of a tribal leader.
