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.
Xiongnu
Coincidentally, the Southern Xiongnu were plagued by natural disasters and misfortunes – in addition to the threat posed by Punu. Consequently, in 50 AD, the Southern Xiongnu submitted to tributary relations with Han China. The system of tribute was considerably tightened by the Han, to keep the Southern Xiongnu under control. The "chanyu" was ordered to establish his court in the Meiji district of Xihe commandery and the Southern Xiongnu were resettled in eight frontier commanderies. At the same time, large numbers of Chinese were also resettled in these commanderies, in mixed Han-Xiongnu settlements.
Economically, the Southern Xiongnu became reliant on trade with the Han.
