Li Yan
However, Zhuge Liang absolved himself from the campaign, and returned to Chengdu to deal with Li Yan. On the way back to Chengdu from Hanzhong Commandery, Zhuge Liang did not reprimand Li Yan, but he secretly preserved Li Yan's letter. When the returning officers greeted the emperor at the imperial palace, Zhuge Liang showed Li Yan's handwritten letter to Liu Shan, so Li Yan could not deny his fault. Then, Zhuge Liang asked Liu Shan to strip Li Yan off all of his titles and official posts and exile him to Zitong Commandery. There, Li Yan lived the rest of his life as a civilian until he heard the news of Zhuge Liang's death in 234, after which he became ill and died.
