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.
Xiongnu
Lajos Ligeti was the first to suggest that the Xiongnu spoke a Yeniseian language. In the early 1960s Edwin Pulleyblank was the first to expand upon this idea with credible evidence. In 2000, Alexander Vovin reanalyzed Pulleyblank's argument and found further support for it by utilizing the most recent reconstruction of Old Chinese phonology by Starostin and Baxter and a single Chinese transcription of a sentence in the language of the Jie people, a member tribe of the Xiongnu Confederacy. Previous Turkic interpretations of the aforementioned sentence do not match the Chinese translation as precisely as using Yeniseian grammar. Pulleybank and D. N. Keightley asserted that the Xiongnu titles "were originally Siberian words but were later borrowed by the Turkic and Mongolic peoples". The Xiongnu language gave to the later Turkic and Mongolian empires a number of important culture words including Turkish tängri, Mongolian tenggeri, was originally the Xiongnu word for “heaven”, chengli (tháːŋ-wrə́j). Titles such as tarqan and tegin and kaghan were also inherited from the Xiongnu language.
