Why is the locust tree in Hongdong, Shanxi the root of the descendants of the Yellow Emperor?

At the end of Yuan Dynasty and the beginning of Ming Dynasty, frequent wars and disasters left many places in the country empty, while the south of Shanxi was prosperous and densely populated. From 137 1 year (the third year of Hongwu) to 14 17 year (the fifteenth year of Yongle), the Ming government set up a bureau in Huaishu, Hongdong. In about 50 years, there have been 18 large-scale relocations, with a total of millions of people, and the relocated population is all over Beijing, Hebei and Henan. Nowadays, the descendants of Sophora japonica immigrants are multiplying all over the country, and even hundreds of millions of immigrants have moved home and abroad. For hundreds of years, the descendants of ancient Sophora japonica have returned to the big Sophora japonica to seek roots and worship their ancestors ... The big Sophora japonica in Hongdong, Shanxi Province is the root of the descendants of the Yellow Emperor.
