臧覇
After the Yellow Turban Rebellion broke out in the 180s, Zang Ba entered the service of Tao Qian, the Governor of Xu Province, and gathered adventurers and gangsters around the area to fight the Yellow Turban rebels. Within his recruits, Sun Guan (), Wu Dun (), Yin Li and Chang Xi () were the most outstanding, and together they protected Xu Province from incursions by the rebels. However, they did not return to Tao Qian after the campaign and instead camped at Kaiyang () and established their own independent regime.
