Why are they all from Shanxi Sophora japonica?

Because there were few wars in Shanxi at that time, there were only 3.78 million people in Henan and Hebei provinces at that time, while there were 4.03 million people in Shanxi, which was smaller than that in Henan. So Zhu Yuanzhang ordered Xu Jimin to divide Ding Yu into Peiping and Lu Yu for farming.

This is the beginning of the great migration of Hongdong in the Ming Dynasty, which has been carried out 18 times, with a population of one million. However, strange problems have arisen. According to the records of Hongdong County, the total population of Hongdong was 92,000 in the 24th year of Ming Hongwu, and only increased to 98,000 in the 8th year of Chenghua. However, the genealogy of millions of immigrants records that their ancestors came from Hongdong.

Introduction to history

In the Ming Dynasty, a relocation office was set up in Hongdong, where immigrants from Shanxi and surrounding provinces were concentrated, sent to Sichuan to take photos, and then set off from Dahuaishu. In other words, there are actually two kinds of immigrants, one is actually moving out of Hongdong, and the other is coming from other areas and concentrated under the big locust tree.

At that time, because the people's educational level was not enough, the concept of zoning was very limited, so the big pagoda tree was engraved in their minds, and when future generations repaired their genealogy, the big pagoda tree passed down from mouth to mouth became their hometown. This is also recorded in the Ming history. For example, ten thousand people in Taiyuan, Pingyang, Ze, Lu, Liao, Qin and Fen in Shanxi live in Beiping, and ten thousand people who have no land in Ze and Lu in Shanxi have gone.
