Pi was killed. In 206, Sima Ju and Xu He attacked a number of cities in Qing Province. Cao Cao sent Xiahou Yuan, Zang Ba, and Lü Qian with a large force to deal with them. After several engagements and heavy casualties on both sides, the two Yellow Turban rebels were killed. Non-Han actors Champa The Cham people in Xianglin, the southernmost district of Rinan Commandery, broke away and became the Kingdom of Lâm Ấp (Champa) in 192. In 248, Lâm Ấp seized Rinan Commandery.

Di The Di (Five Barbarians) were a people related to the Qiang living in what is now Gansu Province. In 213, the Di kings Agui and Qianwan entered an alliance with Ma Chao.
