1. Historically, ethnic minorities were very envious of the development of Han areas and took the initiative to change their names and surnames in order to integrate into the economy and culture of Han people;
2. Emperor Xian of the Han Dynasty occupied the minority areas in the campaign, and then forced the local people to change their surnames in order to consolidate their rule, and gave them names if they contributed;
3. Children of ethnic minorities and Han nationality have marriage leave, and their offspring take the surname of Han parents. Because of the large population of Han nationality, this situation will become more and more as time goes by;
At present, except the Mongolian and Kazak ethnic minorities in the north or west, the names of other ethnic minorities are basically indistinguishable from those of the Han nationality. For example, most Koreans are surnamed Jin or Li, and most Zhuang people are surnamed Wei, but they can't be seen from their names. They can only be judged comprehensively by their national attributes, daily language and clothing in the household registration book.
