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.

After the defeat of Northern Shanyu (1st century), deduced from the number of casualties and immigrants, an estimated figure of 200,000 is given for the Xiongnu still remaining on the northern steppe. Remnants of the Xiongnu managed to keep their identity until the early 5th century, living on the Orkhon River under the tribal name "Bayeqi" (拔也稽) before being eliminated by the Rouran.
