The intensification of the contradiction between Sima Yi and Cao Shuang eventually led Sima Yi to take advantage of Cao Shuang's visit to Gao Ping Ling (Wei Mingdi Mausoleum) and launch a coup in Luoyang, deposing Cao Shuang in the name of the Queen Mother and monopolizing the power of Cao Wei. This is the Gaopingling incident in history.
After this incident, Sima Yi, Sima Shi and Si Mazhao passed down the political position of dominating the state affairs for two generations, and finally Sima Shi abolished Wei Lijin.
Extended data:
In the first month of AD 249, something really happened. 10 years ago, Wei Mingdi entrusted orphans. 10 years later, on the sixth day of the first month, Cao Fangdi took his Cao Shuang brothers to visit the imperial tomb in Gaopingling outside the city. Sima Yi staged a coup in Luoyang, known as the Gao Ping Ling coup in history.
Sima Yi, in the name of the Empress Dowager, closed the city gate, took out weapons, and sent a message to the emperor outside the city, accusing Cao Shuang of abandoning his life and ruining the country, arrogating power to himself from the inside, keeping the supreme, alienating the second palace, hurting his own flesh and blood, threatening the world and making people afraid, and demanding that the emperor remove the relieving of Cao Shuang and his brothers.
Sima yi gave the other party a bait, saying that as long as you hand over the relieving, we will save your life, swear by waterinfo. Cao Shuang's trusted official, Yin Damu, was sent to deliver this message.
Cao Shuang hesitated. First, larger foe. If you do it with Sima Yi, you are afraid that he will fail. Second, if we fight hard, won't our beautiful wife and concubine Meibao in Luoyang be gone? Cao Shuang hesitated all night and decided to surrender, thinking that if he gave up and surrendered the relieving, perhaps Sima Yi would give him a life and become a rich man.
The wily Huan Fan, known as a think tank, specially ran out of the city to dissuade Cao Shuang and told him that a man was holding hostages and wanted to live. Huan Fan wants Cao Shuang to directly confront Sima Yi in the name of the son of heaven! But as Jiang Ji told Sima Yi, although Huan Fan was wise, Cao Shuang would not listen to Huan Fan.
Jiang Ji is right and Huan Fan is wrong. Huan Fan wept bitterly and said, Cao Zidan (Cao Zhen) is really a hero! It's better to have brothers than pigs and dogs! Huan Fan's remarks were repeatedly quoted by Zhao Kun in the Tang Dynasty in the long and short classics, which shows his strategic wisdom. It's a pity that he misjudged people and fell into the hands of Cao Shuang.
In the end, Cao Shuang gave in easily, and Sima Yi failed to keep his promise not to kill. Cao Shuang and others were killed for treason, and Huan Fan also took his life. The power of Cao Wei is completely in the hands of Sima Yi.
