In which province () did the migration of Sophora japonica in the Ming Dynasty take place?

The migration of Sophora japonica in Ming Dynasty took place in present Shanxi Province, which was from Shanxi to Anhui, Henan, Hebei and other provinces. Due to the war and natural disasters at the end of Yuan Dynasty, the balance of population distribution in China was once again destroyed. After the establishment of the Ming Dynasty, Taizu emigrated on a large scale at the suggestion of Liu Jiugao, a doctor of the family.

Among them, Shanxi in the middle reaches of the Yellow River is slightly damaged, and even there is a social problem that "the land is thick and the people are hard to make a living", which is the main area for population migration. According to records, most of them set up a bureau in Guangji Temple in the north of Hongdong County at that time, distributed photos, sent them to designated places, and were placed by the local government.

The Ming Dynasty experienced a 50-year migration of three emperors, covering several provinces in the Central Plains and East China, and covering more than half of China. Its duration, scale and influence are unprecedented not only in the history of China, but also in the history of world immigration. As a part of historical immigrants, immigrants in Ming Dynasty played an important role in history.

In the Ming Dynasty, immigrants strengthened local exchanges, promoted economic development, promoted the change of place names, the distribution of villages and towns, and also changed the distribution of ethnic groups.
