Li Fengji
By fall 825, Li Fengji and Li Cheng had grown to dislike each other. Meanwhile, Li Cheng's relative Li Rengshu (李仍叔) had informed the official Wu Zhao (武昭), who had been stuck in an undesirable position — serving as the secretary general of Emperor Jingzong's granduncle Li Shen (李紳 — not the same person as the official that Li Fengji resented) the Prince of Yuan — that Li Cheng had wanted to give him a better position, but Li Fengji blocked the move. Wu thus resented Li Fengji, and one day, after he got drunk, he told his friend Mao Hui (茅彙) that he wished to kill Li Fengji. This remark was overheard and reported. Li Fengji's associate Li Zhongyan tried to induce Mao into implicating Li Cheng. Mao refused. In the subsequent investigation, Li Zhongyan's attempt to induce Mao to bear false testimony was revealed. As a result of the investigations, Wu was executed by caning, Li Rengshu was demoted, and Mao and Li Zhongyan were both exiled.
