May I ask why Cao Cao's treachery is no match for Sima Yi's treachery?

Cao Cao's treachery has nothing to do with Sima Yi's treachery. If you have to say that Sima Yi is a deceitful person, it is not necessarily, or that I was born to cheat. His deception changes with the change of environment. In the era of Cao Cao, Sima Yi was just an ordinary son with no power and influence. Being an official is also quite satisfactory. In addition to lead Wu Dong and Jiang Ji sneak attack on Jingzhou, there is nothing special. Sima Yi's step-by-step expansion is mainly related to the death of other * * *. When Cao Pi died, he was originally the four ministers of Fuzheng, Cao Zhen, Cao Xiu, Chen Qun and him. Two Cao died young, Chen Qun and he were good friends, and Sima Yi got a chance in the military. When Cao Rui died, Cao Shuang and Cao Yu were ministers entrusted to orphans, but at the suggestion of Sun Tzu and Liu Fang, they were changed to Sima Yi. Sima Yi has no right to Cao Shuang, as long as Cao Shuang is not too bad, Sima Yi is like that.

It is said that the final winner of the Three Kingdoms is Sima Yi, but the result is like this. But he was not born a winner, and he can't predict. Even at the time of his death, the three countries showed no sign of reunification.
