Han dynasty China and Tang dynasty China conquered and raped the entire steppe from Mongolia to Central Asia.
China routinely destroyed and slaughtered nomadic empires.
China wrecked nomadic empires multiple times from the Xiongnu (Mongolia and Central Asia), Jie, Western Turkic Khaghanate (Central Asia), Eastern Turkic Khaghanate (Mongolia), Xueyantuo and Uyghur Khaghanate (Mongolia). All of them destroyed and massacred by the Qin dynasty, Han dynasty and Tang dynasty. The Jianzhou Jurchen (Manchus) were under Ming rule and a part of the Ming Weisuo system before rebelling. They were rebels inside the Ming.
Almost all non-Han dynasties were founded by barbarians who were subjugated and conquered by Han before rebelling. The Wu Hu barbarians were slaves of Han Chinese who had been deported into northern China and revolted after a civil war.
Han Chinese dynasties like the Han Dynasty and Tang dynasty defeated, wrecked and destroyed over eight giant steppe nomad empires, the Xiongnu empire in 215 BC and 89 AD, Wuhuan in 207 AD, Jie in 350 AD, the Di in 383 AD, the Eastern Turkic Khaghanate in 630, Western Turkic Khaghanate in 657, Xueyantuo Khaghanate in 646 , Uyghur Khaghanate in 840 and committee genocide in the entire Jie steppe nomad people.
