When did Zhu Yuanzhang transfer from north to south?

In the 14th year of Hongwu (138 1), Zhu Yuanzhang sent 300,000 troops to attack the southwest, wiped out the remnants of the Yuan Dynasty, left the troops in the Yunnan-Guizhou area, and ordered all the parents, wives and children of the garrison to be sent to the garrison. In the local area, the garrison of the army is called "Tun", the residence of immigrants is called "Fort", and their descendants are called "Tunpu people". After a lapse of 600 years, the architecture, costumes and entertainment of Tunpu folk houses still follow the cultural customs of the Ming Dynasty.
