賈充
In 260, the Wei emperor Cao Mao, unable to contain his anger about Sima Zhao's monopolisation of power, attempted a coup d'état to try to take back power from the regent. When forces led by Sima Zhao's brother Sima Zhou quickly collapsed against Cao Mao's forces, it was Jia Chong who was willing to stand against the emperor and who further ordered his subordinate, Cheng Ji (成濟), to take any measure to defeat the emperor and his loyalists. Cheng Ji killed Cao Mao by spearing him to death. In the aftermath of the incident, the people demanded for Cheng Ji and Jia Chong to be executed. Sima Zhao considered the matter for more than 10 days, eventually resolving to kill Cheng Ji (and his clan) but sparing Jia Chong, not wanting to execute someone who had been so loyal to him. From that point on, however, Jia Chong's reputation among the people was one of regicide.
