简介：In the middle and late Ming Dynasty, due to the victory in the perennial war against Mongolia, Mongolia formally professed its vassalage to the Ming Empire, and the trade channel with Mongolia was opened.

Horses have caused private horse farms in Hebei and Shandong to close down and change careers.
