Noin-Ula burial site
The cultural affinity of the Xiongnu was with the peoples of southern Siberia and Central Asia; with the Chinese they exchanged arrows rather than culture: the Xiongnu shot with hand bows, while Chinese employed crossbows, although the Chinese had developed the crossbow from the traditional hand bows. Lev Gumilev elaborates the roots of the Chinese cultural influence found in the Noin-Ula cemetery. The Chinese culture was spread not only by material objects, but also by population admixture. There were populations of Xiongnu that have live under the Han rule as military allies. The Chinese migrated continuously to the steppes, the first big wave arriving in the 3rd century BC during the Tsin dynasty (Pin. "Qin"), when captured Chinese became subjects of the Chanuys, a process repeated during the following centuries. The numerous Han people who deserted and entered Chanuy service (for example, Vey Lüy, Li Lin) also taught the Xiongnu the subtlety of diplomacy and martial arts. Populations of the Xiongnu people also lived under Han rule, mostly serving as military allies under Han command. The capture of populations of Xiongnu by the Han forces in a series of Han versus Hun wars also contributed to additional ethnic integration of the north-central Asian neighbors.

By the 280s, a huge number (approximately 400,000) of Xiongnu herdsmen resided in the Ordos Desert and Bing, a political division including modern-day areas of the whole Shanxi province, southwestern part of Inner Mongolia and eastern part of Shaanxi province, after Cao Cao moved them there and split them into "five departments" (五部, pinyin Wǔbù). The Southern Xiongnu continued their nomadic lifestyles of the steppes with horse breeding and to some extent agriculture. In spite of significant loss of Chinese sedentary population, the Chinese portion of the population in the state is estimated to be around 1,500,000. In addition to the Southern Xiongnu nomads, the state numbered 1,000,000 of other nomadic tribes, mainly Jie, Xianbei, Di, and Qiang, for a total of approximately 1,400,000 nomadic population, or 200 thousand yurts.
