Many immigrants lived in the Xiongnu pasturelands, but at first they did not mix with the Xiongnu. To be a Xiongnu, one had to be a member of a clan, born of Xiongnu parents. The newcomers were well off, but were outsiders, and could marry only among themselves, not the Xiongnu. Only later did they intermix, increase in numbers, even created a state that existed from 318 to 350 AD.
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.
