Jia Chong
In 260, the Wei emperor Cao Mao launched a coup in an attempt to seize back power from the regent Sima Zhao, but failed and ended up being assassinated by an officer serving under Jia Chong, one of Sima Zhao's close aides. Chen Tai tried to rush to the scene to defuse tensions, but he showed up too late. Upon seeing Cao Mao's dead body, he wept and refused to attend imperial court sessions as a protest against the emperor's assassination. However, he relented and returned to work after Sima Fu, a highly respected Wei official and uncle of Sima Zhao, persuaded him to do so. Jia Chong took responsibility for Cao Mao's death but Sima Zhao spared him and had the officer executed instead; Chen Tai strongly opposed Sima Zhao's decision and urged him to execute Jia Chong but the regent refused. Chen Tai died in distress not long later.
