《明史·列传·卷二百一十五》
我的亡父太祖高皇帝对元朝人的子孙，总是有意抚慰体恤，凡是来归顺的，总是让他们回到北方老家，例如把脱古思帖木儿送回去，他的子孙成为可汗，这些都是南北方人所共同知晓的。
我皇考太祖高皇帝于元氏子孙，加意抚恤，来归者辄令北还，如遣脱古思帖木儿归，嗣为可汗，此南北人所共知。
My deceased father, Emperor Taizu Gao, always intended to comfort and show kindness to the descendants of the Yuan people. All those who came to surrender were always allowed to return to their old homes in the north. For example, Tuoguistumur was sent back and his descendants became khans. These are things that people in both the north and the south know.
