Si Mazhao was wei ren in the Three Kingdoms period. His father's name is Sima Yi, and he is a general of Wei State. After Wei Mingdi's death, Cao Shuang and Sima Yi were entrusted to assist Cao Fang, the king of Qi, to govern the world. Cao Shuang and Sima Yi pushed each other out. After a fierce power struggle, Sima Yi tried to punish Cao Shuang, and the military and political power of Wei fell into Sima Yi's hands.

After Sima Yi's death, his eldest son, Sima Shi, quickly abolished Cao Fang, who was an adult but failed to lead the government, and made 13-year-old Cao Mao emperor, more powerful than Sima Yi, but soon died of illness. When Sima Shi was seriously ill, he gave power to his younger brother Si Mazhao.

After Si Mazhao came to power, he was even more ambitious and always wanted to replace Cao Mao. He kept rooting out dissidents and attacking political enemies. Young Cao Mao knew that even if he was a "puppet" emperor, he wouldn't last long, and he would be removed by Si Mazhao sooner or later, so he planned to take risks and kill Si Mazhao by surprise.

One day, Cao Pi called his confidant ministers and said, "Everyone knows Si Mazhao's heart. I can't stand the shame of being overthrown in vain. I want you to crusade against him with me. " Several ministers knew that doing so was tantamount to throwing a moth into a fire and advised him to be patient for a while.

A man named Wang Jing who was present at that time said to Cao Mao: "Now the power is in Si Mazhao's hands, and the civil servants in the Qing Dynasty are all his people; Your majesty, you are weak and weak, and the consequences are unimaginable if you act rashly. You should think carefully. "

Cao Mao refused to accept the suggestion and personally led hundreds of servants and guards to attack Si Mazhao. Who knows that some ministers have reported the news to Si Mazhao. Si Mazhao immediately sent troops to intercept and killed Cao Mao.

Second, the source of "Si Mazhao's heart is well known":

From The History of the Three Kingdoms, Shu Wei San Shao Di, Ji Gui Xiang Gong Biography, Pei Songzhi quoted Hanshu Chunqiu: "Everyone knows Si Mazhao's heart. I can't just sit back and wait. Today, I should ask Qing (and others). "

"Everyone knows Si Mazhao's heart" means that ambition is very obvious and well known. Si Mazhao was Chen Wei in the Three Kingdoms period. After his father Sima Yi and his younger brother Sima Shi, he continued to develop the power of Sima family and was in power in the ruling and opposition parties.

Cao Pi, the Wei Emperor, described his ambition as "everyone knows the heart of Si Mazhao". Later, he led a crusade against Si Mazhao and was stabbed to death by his henchmen, while Si Mazhao was not investigated. Later, he was made King of Jin. After his death, his son Sima Yan usurped Wei's right to self-reliance. Later, people used the phrase "Si Mazhao's heart is well known" to illustrate that the conspirators' ambition is very obvious and well known.
