What are the characteristics of induction in the Research Report on Li's History and Present Situation?

Don't study such general things. Li is the world's largest surname, and its source is super complicated. There are many branches, and some branches are not related at all. Only * * takes Chinese characters as their surnames. If you want to study, you will lack a lot of data support, and it is very likely that the tributary will be regarded as the mainstream and the lateral center as the center. If you want to learn, I tell you, just learn a certain sect, such as Longxi Li, Jinyang Li and Handan Li.
