What are the big locust tree immigrants, Han people?

The background of Sophora japonica migration is that due to the cruel rule of Yuan Dynasty and years of war, Shandong, Henan and southern Hebei are thousands of miles apart and inaccessible. In order to restore social vitality, Zhu Yuanzhang decided to immigrate to Shandong, Henan and other places on a large scale from the relatively densely populated southern Shanxi area. At first, it was mainly voluntary, and later it became compulsory. In that case, who cares what nationality it is? What's more, there was no strict ethnic policy at that time, as long as people could be caught. Therefore, not only the Han people immigrated to the tree, but also many people from other nationalities, but these people were relatively few, and they were quickly assimilated by the Han people after leaving the original nationality.
