Xiongnu
The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.
Xunyu
Based on phonetical studies and comparisons of inscriptions on bronze and the structure of the characters, Wang Guowei (1877–1927) came to the conclusion that the tribal names Guifang (鬼方), Xunyu, Xianyu (鮮虞), Xianyun (獫狁), Rong, Di, and Hu in the old annals designated one and the same people, who later entered Chinese history under the name Xiongnu, and Eurasian history under the name Huns.
