In which dynasty did large-scale migration occur in Shanxi?

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, Mongolian aristocrats Chahan Iron Eureka and Kuoko Iron Eureka used favorable terrain to defend one side and were less affected by war. Residents of North China Plain took refuge in Shanxi, which made the economy and population more prosperous than other areas. According to historical records, 138 1 year, the population of Hebei and Henan is only180,000, and there are more than 4 million in Shanxi, mostly concentrated in the south of Shanxi.

After Zhu Yuanzhang unified the whole country, in order to restore and develop the economy, he implemented the system of reclamation. 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.

The migration of Sophora japonica started in the early Ming Dynasty and lasted for more than 100 years. During the Hongwu period alone, hundreds of thousands of people moved out of Hongdong area. Some are directly distributed in Hebei, Shandong, Henan, Anhui and other provinces, and some are indirectly distributed in Sichuan, Yunnan, Guizhou, Northeast China, Inner Mongolia and other places. When reclaiming land, the state gives cattle, seeds and land rent-free for three years. Through the hard work of immigrants, the cultivated land area in the original desolate area has been greatly increased, and agricultural production has been restored and developed. At the same time, it has also contributed to consolidating border defense and promoting national integration and cultural exchanges. Because these immigrants went through the immigration formalities under the locust tree in Hongdong, they regarded this place as their hometown. Up to now, the proverb "Ask where my ancestors came from, Sophora japonica in Hongtong, Shanxi" is still circulating in the north of China.

The old Sophora japonica has long since disappeared, and the only dry matter of the old Sophora japonica is the second generation of the original Sophora japonica. Now there is a new locust tree, with lush foliage, which is the third generation. 192 1 year, Ren Jing Daqi, an official from Hongdong, Shandong Province, was well aware of the yearning of immigrants from the Central Plains provinces for Sophora japonica, and proposed to raise funds to erect a monument to build a workshop.
