Where is the migration place of Sophora japonica in Gansu Province?

It should be Shanxi Guohuai ~ Hongtong County, Shanxi Province.

Sophora japonica in Hongdong, because in the Ming Dynasty, the Ming government set up a bureau here to deal with immigration affairs, and Sophora japonica became a gathering place for immigrants.

At that time, all immigrants had to come to the big locust tree to receive "Sichuan capital" and then set off. Sophora japonica is deeply rooted in the hearts of these immigrants and their descendants for generations. Many descendants of immigrants also recorded in their genealogy that their ancestors came from Sophora japonica.

It is said that during immigration, officers and men will cut a knife on each immigrant's little toe as a mark, so until today, the little toenails on the feet of Hu Aixiang immigrants' descendants have two petals. You might as well look it up yourself.

When migrating, officers and men often use the form of anti-binding to prevent people from escaping on the way, and then connect them with long ropes to escort them on the road. Because of the long distance and time, carrying hands has become a habit. Most immigrants still like to walk with their hands behind their backs, and their descendants also follow the habit of factories.
