Longnan is very important in Chinese history: it was the home of Rong tribes that troubled the Shang and Zhou dynasties and is considered the homeland of the House of Ying, the family of the Qin dynasty that united China at the end of the Warring States period.
964 BCE: King Mu of Zhou defeated the Quanrong and the following year attacked the Western Rong and Xurong.
When the (c. 4th BCE) Classic of Rites recorded stereotypes about the Siyi "Four Barbarians" (Dongyi, Xirong, Nanman, and Beidi) in the four directions, Dongyi had acquired a clearly pejorative nuance.
The Xirong tribes that lived near Qin also rebelled, exterminating the senior branch of the House of Ying at Quanqiu (present-day Lixian in Gansu).
