李希烈
As of 779, Li Zhongchen was said to be greedy, violent, and sexually immoral. If his officers and soldiers had beautiful wives or daughters, he would often force the women to have sexual relations with him. He entrusted the important matters of the circuit to his brother-in-law Zhang Huiguang (), whom he made his deputy. Zhang was said to be corrupt and causing much grief to the soldiers. Zhang's son, an officer, was even more corrupt than his father. Li Xilie was supported by the soldiers, and he took this opportunity to plot a mutiny with his colleague Ding Gao (). On March 28, 779, Li Xilie and Ding killed Zhang and his son and expelled Li Zhongchen. Li Zhongchen fled to Chang'an. Emperor Daizong, crediting him for his past achievements, kept him at Chang'an and gave him the honorary title of acting "Sikong" (司空, one of the Three Excellencies) and allowed him to exercise his previously-honorary authorities as a chancellor. He made Li Xilie prefect of Huaixi's capital Cai Prefecture () and acting military governor (nominally serving under Emperor Daizong's own son Li Zao () the Prince of Xin), but stripped the circuit of Bian (汴州, in modern Kaifeng, Henan) and Ying (潁州, in modern Fuyang, Anhui) Prefectures, transferring them to Yongping Circuit () under Li Mian's command, moving Yongping's headquarters to Bian Prefecture. After Emperor Daizong died later in the year and was succeeded by his son Emperor Dezong, Emperor Dezong formally made Li Xilie the military governor of Huaixi.
