Population migration in Yongle period

In fact, many people died after the battle of Ming Chengzu and others, but Shanxi was relatively unaffected by the war and had a large population, so they ordered people from Shanxi to move to other places. At that time, a big family built a genealogy, which recorded that they came from the big locust tree in Hongdong County, Shanxi Province, while other Shanxi people didn't know which county they were from, but they were all in Shanxi anyway, so they said they were from there. In fact, think about it, there are so many people living under the big locust tree.

Write so much, give me a high score.
