The Xiongnu are also the ancestors of the Mongolian people.

The Xiongnu were the predecessor of Mongolia. The Mongols originated from the Mengwu Shiwei, a branch of the Donghu. The Wuhuan and Xianbei tribes in the east of the Xiongnu were called "Donghu", and the oasis people in the Western Regions to the west of the Xiongnu were called "Xihu".

The Xiongnu were a nomadic people who arose in the 3rd century BC and "lived in pursuit of water and grass".

According to records in "Historical Records: Biography of the Xiongnu", the Xiongnu were the descendants of their ancestors, the Xia Hou family, and were named Chunwei.

The Xiahou surname is the surname of the monarch of the Xia Dynasty, the first hereditary dynasty in our country. After the death of Xia Jie, the last king of the Xia Dynasty, Xun Yu, the son of Xia Jie, took Xia Jie's concubines for his own use and took refuge in the desert of the northern barbarians.

The land has multiplied from generation to generation. This is the origin of the Xiongnu.

Extended information: The Xiongnu became powerful in the early Western Han Dynasty and invaded the border repeatedly, posing a strong threat to the Western Han Dynasty and controlling the Western Regions. It was not until Emperor Yuan of the Han Dynasty that Wang Zhaojun came out of the country to marry a Xiongnu Chanyu in order to stabilize the peace on the border.

In the later period, there was internal turmoil among the Xiongnu for the throne, and the Xiongnu split into northern and southern Xiongnu. The Han Dynasty took the opportunity to drive the northern Xiongnu to Central Asia.

The Southern Xiongnu surrendered to the Han Dynasty and were resettled in the Monan area from Qingyang, Ningxia, Shanxi, Shaanxi, Hebei Province in today's Gansu Province, and Hohhot to Baotou in Inner Mongolia.

With the passage of time, the southern Huns were gradually sinicized, and the Mongols, Turks, Khitans, etc. were all their descendants. This is also what the "Hulu" and "Xiongnu" in Yue Fei's poems refer to.
