In what year did the Liu family move to Henan from Hongtong County, Shanxi Province?

"Ask where the ancestors came from, Shanxi Hongdong locust tree, ask where the ancestral home is, and Shanxi Hongdong old stork nest." The migration of Sophora japonica in Hongdong began in Song and Jin Dynasties and continued to this day in the early Yuan Dynasty, but it formed a large-scale government-organized migration activity in the early Ming Dynasty. The migration activities in Ming dynasty continued in Ming dynasty, but mainly in Hongwu and Yongle years. During the reign of Qing Qianlong, this kind of activity continued, but sporadically.

At the end of the Yuan Dynasty, the frequent wars in the Central Plains, coupled with natural disasters and epidemics, made a large number of people scattered around and desolate everywhere. In Shanxi, however, because Mongolians Chahan Tieogura and Kuoko Tieogura took advantage of favorable terrain and were on one side, there were fewer war disasters. Residents of North China Plain came to Shanxi to take refuge, which led to a more prosperous economy and population than other regions. According to historical records, 138 1 year, the population of Hebei and Henan is only180,000 each, and there are more than 40 million in Shanxi, mostly concentrated in the south of Shanxi.

According to Lu, the fourteen years of Hongwu were 138 1, the population of Henan was 189 1000, the population of Hebei was 1893000, and the population of Shanxi was 4030450, which was more than that of Henan and Hebei. )

After Zhu Yuanzhang unified the Central Plains, in order to restore and develop the economy, the system of reclamation was implemented. The densely populated Pingyang county has become an important area for immigrants. Farmers who moved from counties first concentrated in the villages around the big locust tree in Hongdong, went through the formalities in Guangji Temple where the big locust tree was located, and then set foot on the journey in groups and moved to different places. As for the migration of the Liu family, it is also one after another, not moving out at once. Besides, the Liu family not only moved to Henan, but also moved to many provinces in China.
