Cao Cao has so many descendants, why does no one dare to stop Sima Yi in the face of usurpation?

The main reason for this is because Sima Yi has great power in his hands, and Sima Yi's group controls a lot of Cao Wei's military power and financial resources. The power in his hands is great, so no one dares to stop him.

Because when the brothers of the Cao family were fighting for the throne, Sima Yi had already hollowed out Cao Wei's power, so in the end, Sima Yi's power was monstrous, and naturally no one dared to stop him from usurping the throne.

The ability of Cao Cao's descendants is far worse than Cao Cao's, and they cannot restrain the Sima family, in the final analysis, it is still a matter of the ability of the descendants.

The Cao family has serious infighting, Sima Yi is too talented, knows how to disguise himself, can be good at forbearance, and launched a coup d'état in the end.

This matter is inseparable from Cao Pi, during his reign, the prevention of the Cao clan like a thief, resulting in the Cao clan's strength being greatly weakened, and it was in his hands that Sima Yi's fate began to reverse and began to enter the political center. Another reason is that Sima Yi is so capable of staying up, he survived three generations of Cao Cao, Cao Pi, and Cao Rong in a row, and finally seized power in the hands of Cao Fang, paving the way for the Sima family to usurp the throne.

The main reason is that Cao Cao's descendants were all gentlemen at that time, and some of their behaviors also fueled the arrogance of the other party and gave the other party great rights, so it led to such behavior.

Because these four famous generals are loyal, all of them are brave and mighty generals, if they are there, it will be difficult for Cao Cao to be usurped by power.

Because these four famous generals are Cao Cao's henchmen, Cao Cao regards them as his relatives. Therefore, once Sima Yi wanted to rebel, the four of them would not agree to bear the brunt, and Sima Yi's life would not be guaranteed.

Because Sima Yi is very afraid of them, if they are there, Sima Yi will not dare to usurp power so calmly.

Cao Cao used the name of the Han Dynasty to carry out the war of national unification and serve the common people.

Sima Yi is coerced by selfish desires, fighting for power and profit, and playing conspiracy.

Cao Cao was the prime minister until his death, and he was not called the emperor, even if he pulled a puppet emperor, it was different in the eyes of scholars at that time. Moreover, Cao Cao's descendants are more capable, and his sons and grandsons govern Wei quite well. Sima Yi is actually a very capable person, he has never been called the emperor, his son is called the emperor, but his descendants of the Jin State hurt China a lot, after the Eight Kings Rebellion was a devastating blow to the Han people, Sima Yi's reputation was defeated in the hands of his children and grandchildren, and the black cauldron was carried for his descendants.

Because Cao Cao's son had been deprived of military power by Sima Yi at that time, and Sima Yi firmly controlled it.

The Cao clan's forces were too weak to resist. Moreover, Cao Pi and Cao Rui lived very shortly, the later prince was young, and Sima Yi was very long-lived, holding a lot of power, and the qualifications were old, and the Cao family was powerless to resist.

Because Cao Cao's other sons have no real power, it doesn't help. After Cao Cao's death, Sima Yi began to prepare his own actions, and with the help of Cao Pi's hands, he deprived Cao Cao's other sons of their rights.

Because of fear. At that time, Sima Yi held the power of the army, and Sima Yi also trained a lot of soldiers, and the Cao family could no longer fight against him.
