Cao Mao
In 260, the Wei emperor Cao Mao summoned Wang Jing, Wang Chen and Wang Ye to meet him in private and discuss plans to launch a coup to seize back power from the regent Sima Zhao. Cao Mao did not heed Wang Jing's suggestion and proceeded with the coup, but ended up being assassinated by Sima Zhao's men. After Cao Mao's death, Sima Zhao had Wang Jing and his mother arrested and executed.
