Historical background of westward advancement.

Immigrants from the west have a profound historical background.

In the early Ming Dynasty, the imperial court set up the "Nine Borders" (nine military regions) to defend the northern frontier. More than 800,000 troops and more than 300,000 war horses stationed in the border areas have caused great pressure on the finances of * * *.

Hongwu began to implement the system of changing grain into salt in three years, which brought an opportunity for the formation of Shanxi merchants.

In the mid-Ming Dynasty, horse markets were opened in Zhangjiakou and Shahukou, which greatly promoted the transformation of Shanxi merchants from salt industry to diversified management.

However, businessmen were not allowed to do business in the hinterland of Mongolia in the Ming Dynasty, so border trade was greatly restricted.

After the Ming and Qing Dynasties, the northern border moved forward, and Kangxi conquered Geerdan, quelling the pounding of hooves in the northwest and breaking the previous ban on Han Chinese entering Mongolia.

Hequ people, separated from the Mongolian grassland by water, got there first, and then crossed the river to the north one after another, and came to the Mongolian grassland for reclamation and development.

Because Mongols are not good at farming, and thousands of miles south of Daqingshan are cultivated land, this provides a place for brothers who want to go west.
