Li Fengji
In 825, there was an incident in which one Wu Zhao (武昭) was accused of threatening to kill Li Fengji. Previously, after Wu had served as a prefectural prefect, he sought a better appointment, but was given the largely powerless position of serving as secretary general to Emperor Jingzong's granduncle Li Shen (李紳) the Prince of Yuan. Li Cheng, who was friendly with Wu, wanted to give Wu a more useful position, but Li Fengji, who by that point was no longer friendly to Li Cheng, opposed, and Li Cheng's relative Li Rengshu (李仍叔) informed Wu of this. Once, when Wu became drunk, he made the remark to his friend Mao Hui (茅彙) that he was going to kill Li Fengji. When this was reported, Wu was arrested. Li Fengji's follower Li Zhongyan suggested to Mao that, if Mao was willing to implicate Li Cheng, he would be rewarded. Mao refused. As a result of the subsequent investigations, Wu was executed by caning; Li Rengshu was demoted; and Li Zhongyan and Mao were exiled.
