Gao Pian
Lü Yongzhi (呂用之) (d. December 29, 887) was a Chinese magician, military general, and politician during the late medieval Tang Dynasty, who became trusted by Gao Pian the military governor ("Jiedushi") of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu) and became very powerful at Huainan, at one point becoming more powerful than Gao himself. Subsequently, Gao's officer Bi Shiduo rose in resistance, plunging the circuit into intense internecine warfare. Lü, after Bi defeated him, aligned himself with Yang Xingmi, but after Yang's victory over Bi and Qin Yan, Yang executed him.
