What was the Ming Dynasty's view of Xiongnu?

Xiongnu is a northern nation with a long history, and its ancestors lived in Siberia in Eurasia. Xiongnu in China ancient books is a powerful nomadic people who ruled the northern part of the Central Plains in the late Qin Dynasty and early Han Dynasty. Defeated by Emperor Wu of the Western Han Dynasty, he retreated to Mobei and split into five parts. During the Han and Yuan Dynasties, he divided Xie Han and his relatives into five parts. Later, in the Eastern Han Dynasty, it was divided into the northern and southern Xiongnu, and the southern Xiongnu surrendered to the Han Dynasty. After the westward migration, the northern Xiongnu disappeared into China's ancient books. So there were no Huns in the Ming Dynasty.
