at the end of the eastern Han dynasty, heroes competed for the world. During that period of intrigue and turmoil, it was not surprising that those in power were driven to exterminate the future trouble. They were not afraid of being accused of cruelty by future generations, just for their peaceful mastery of power and no worries. Cao Shuang's three clans were executed by Sima Yi, but one of them was left out
As we all know, Sima Yi seized a very prominent position and power for Sima Jia by his own strength, and later he became an important courtier in charge of Wei's state affairs, which is why Sima Yi became Zhuge Liang's worry. When Wei Mingdi's son just succeeded to the throne, he was still very young and could not properly handle all kinds of government affairs. At that time, his two most trusted ministers were Sima Yi and Cao Shuang.
At first, Sima Yi was not in power very smoothly, so he was ostracized by Cao Shuang and others. What's more, Cao Shuang even advised the Emperor to demote Sima Yi as a teacher without real power. Cao Shuang ran amok on the court by relying on his power, which caused resentment and dissatisfaction from Sima Yi and other ministers. Later, in order to seize power, Sima Yi took advantage of the emperor's unprepared, occupied Luoyang, Kyoto, alone, and wiped out the three families of Cao Shuang by virtue of military and political power, but he neglected to leave a person behind.
This man is Huan Fan's youngest son, Huan Kai, who didn't dare to have the slightest idea of revenge when Sima's family was still in power, so he just hid. But later, this little person who was not regarded by anyone brought endless troubles to Sima's family.
After a long period of self-cultivation, the Huan family finally led the army to rise, and Huan Wen, a descendant of Huan Kai, became a leader in the Eastern Jin Dynasty, dominating the party and becoming an independent regime, creating a world for his descendants. Finally, the Huan family destroyed the Sima family. The wind and water turn around, and the heaven is good, which eventually leads to such a situation, but it is just retribution for Sima Yi's use of improper means to seize power.
