Shanyu

Chanyu (Chinese: 單于; Chinese: 单于; pinyin: Chányú; short form for Chengli Gutu Chanyu (Chinese: 撐犁孤塗單于; pinyin: Chēnglí Gūtu Chányú)) was the title used by the nomadic supreme rulers of Middle and Central Asia for eight centuries and was superseded by the title "Khagan" in 402 CE. The title was used by the ruling Luandi clan of the Xiongnu during the Qin dynasty (221-206 BCE) and Han dynasty (206 BCE–220 CE).

According to Book of Han, Chēnglí 撐犁 means "heaven", gūtu 孤塗 "son" and chányú 單于 "immense appearance". Chengli might be a Chinese transcription of Tengri, the Turkic sky god, in which case the title means "The Son of Tengri".
