My family lives in Bashang area of Zhangjiakou, and my surname is Wu. My family said that my ancestors belonged to Shanxi Sophora japonica. How can I verify it?

There have been a lot of activities over there in recent years. It's just an activity to find the roots and ask the ancestors. You can learn about it from the internet. If you have a long family tree, family tree. Can reflect each other's certificates. Otherwise, it will be more difficult.

Strictly speaking. The migration of Sophora japonica occurred in the middle of Ming Dynasty. 14XX year. 15th century. What about Bashang? /kloc-in the 0/5th century, there were basically no people, all of whom were Mongolian nomads. The real immigrants from Bashang began in the late Qing Dynasty and early Ming Dynasty. That is, around 1900, it was one of the three major waves of immigration in Qing dynasty, that is, western immigration (the other two were to Kanto and the lower level of Southeast Asia).

So, if your home is really big, that's right. The most likely way to emigrate is: from Sophora japonica to Zhangjiakou or Baoding, Hebei Province in the Ming Dynasty. Then in the early years of the Republic of China, because of the troubled times under the dam. So I immigrated to Bashang again.
