The origin of the idiom "Sima Zhao's heart, known to passers-by" can be traced back to the "Three Kingdoms Zhi Wei Shu Three Young Emperors", mainly involving the story of Sima Zhao, a powerful minister of the Wei state during the Three Kingdoms period.

At the end of the Wei state during the Three Kingdoms era, Sima Yi launched a mutiny to destroy the Cao Shuang clique, and from then on, the power of the Wei state completely fell into the hands of the Sima clan. Sima Yi's two sons, Sima Shi and Sima Zhao, also held heavy military power. Later, Sima Zhao was promoted from general to Xiangguo and was made the Duke of Jin, intimidating the Wei emperor Cao Xin. Seeing that his power was weakening day by day, Cao Xian felt resentful, and he really could not bear this life as a puppet emperor, so he summoned three people, Wang Shen, Shangshu Wang Jing, and Wang Ye, a regular attendant, and said to them: "Sima Zhao's heart is known to passers-by. I cannot sit and wait for him to come and clean me up and suffer the shame of being deposed, and today I will personally go out with you to fight him and eradicate this rebel thief. ”

Subsequently, Cao Xin tried to resist, but was killed by Sima Zhao's subordinate Jia Chong and others. Since then, people have used the idiom "Sima Zhao's heart, everyone knows it" to describe the ambition of conspirators or powerful ministers, which has reached the point where everyone knows and no one knows. #Sima Zhao##檀健次#
