Li Fengji
In 824, Emperor Muzong died and was succeeded by his son Emperor Jingzong. After Emperor Jingzong's ascension, the chancellor Li Fengji became very powerful. Li Fengji was resentful of the official Li Shen, and thus falsely accused LI Shen of not supporting Emperor Jingzong and instead wanting to support Emperor Muzong's brother Li Cong (李悰) the Prince of Shen. Li Shen was exiled, and Li Fengji further tried to have Emperor Jingzong order Li Shen's death. Wei Chuhou, who passed the imperial examinations in the same year as Li Shen, submitted a defense of Li Shen, pointing out that there was no real evidence of Li Shen's alleged crime and that, as Li Shen was a close advisor of Emperor Muzong's, Emperor Jingzong should not be acting against him so quick after Emperor Muzong's death. When Emperor Jingzong subsequently discovered a petition in the archives in which Li Shen sought to have Emperor Jingzong created crown prince, Li Shen was spared.
