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.
Xirong
Xirong () or Rong were various people who lived primarily in and around the extremities of ancient China known as early as the Shang dynasty (1765–1122 BCE). They were typically to the west (in modern Gansu, etc.) of the later Zhou state from the Zhou Dynasty (1046–221 BCE) onwards. They were mentioned in some ancient Chinese texts as perhaps related to the people of the Chinese civilization.
