Because the degree of Chineseization in the previous period was not deep, the naming was more casual, and still retained the characteristics of naming by ethnic minorities; later, as the influence of Han culture became more and more profound, naming should follow the order of the genealogy, that is, The first character of the name is arranged according to seniority. People of the same generation are the same, except of course the emperor, to avoid taboos. This is a general rule for ethnic minorities taking over the Central Plains. That is, although they temporarily conquer the Han people by force, their culture is always affected to varying degrees. This is not limited to the issue of names.
