At the end of the Yuan Dynasty and the beginning of the Ming Dynasty, the war was continuous, once the war broke out, floods, droughts, locusts continued, according to the "History of the Yuan" recorded that during the late Yuan Dynasty, rain and drought alone occurred 19 times in Shandong, 17 times in Henan, 15 times in Hebei, and 8 times in the two Huai regions.
In the "History of Yuan" or "Five Elements of the History of the Yuan" can be seen: "Grass does not enter the land, people cannibalize", in order to avoid cholera, the people began to migrate south, after the establishment of the Ming Dynasty, the Central Plains area seriously lack of labor, the Ming Taizu period in order to introduce labor force to use immigrant Tuntian.
Although the Central Plains regained some vitality, but the Battle of Jingnan broke out, Ming Chengzu led troops all the way in, the Central Plains moved again, they went all the way to the Shanxi area, Hongwu about fourteen years, shanxi population reached 4.03 million, while Henan only 1.8 million people, Hebei 1.89 million.
Ming Chengzu would not sit idly by and ignore this imbalance, and in the first year of Yongle, Ming Chengzu issued an edict that the people sent to the frontier would be sent to Beijing and wearing sin to cultivate fields in Beijing, but this only did not restore the vitality of the Central Plains, so Ming Chengzu ordered a forced relocation, and officials everywhere spread the "Qishan Plan" in order to complete the task.
They told the fleeing people that there was only Hongdong County in Shanxi, and that only people from Zaoqiang County in Hebei did not migrate to Shandong, and that people from other counties were moving to Shandong.
When the time was almost right, the officers and men surrounded them, tied them up one by one, and forcibly escorted them to Shandong, and these people all cried and refused to leave, so in order to make it easier for them to find their roots in the future, the officers and soldiers gathered them under the big locust tree and cut a knife to the small toe, so Shanxi had the saying "Who is the person under the ancient locust, the little toe of the foot to check the shape of the nails" and "where the eagle nest is now, sitting on the sangzi armor."
The Ming Yongle Great Migration is the largest, most extensive and longest migration in China, this migration is as long as 50 years, involving 812 surnames, and tens of thousands of descendants who have moved from here to various places, so every year people come to the big locust tree to recognize their ancestors.
