The Huns themselves have no writing, and all the records about them come from ancient books in West Asia, Europe and China, so it is very difficult to make textual research.

According to the current historical records, the Huns first appeared in history in 3 18 BC, that is, during the Warring States Period in China.

As a political power, it began in 209 BC when Morton Khan killed his father to stand on his own feet and unified the grassland. Until around 160, the northern Xiongnu Khan moved westward, and the Xiongnu slavery regime existed in the north and south of the desert for 300 years. It is basically equivalent to the period from the end of the Qin Dynasty to the Han Emperor in the Eastern Han Dynasty (one of the two emperors that Zhuge Liang said led to the decline of the Han Dynasty).

Since then, the discrete Huns have been active in the history of China for nearly two hundred years.

It was not until the end of the Northern and Southern Dynasties that Xiongnu gradually disappeared from China's historical records.

As a nation, it should have existed for a long time, but it lacks relevant historical evidence. It is said that it may be that the descendants of Xia Jie fled Shang Tang and fled to the grassland, which gradually bred such a barbaric and ferocious nation and brought great disasters to the Han nationality.
