In fact, we all know that "The Romance of the Three Kingdoms" is a masterpiece of historical wars during the Three Kingdoms period. It can be said that this book has written many wise sayings that have been passed down through the ages. There is such a sentence in the book, Sima Zhao Zhixin is known to everyone on the road. This sentence was said by Cao Mao, the puppet emperor at that time. So under what circumstances did he say it? Let's take a look.

Let’s talk about Sima Zhao first. Sima Zhao was a native of Wei during the Three Kingdoms period. His father, Sima Yi, was a man who knew how to endure. He successfully defeated Zhuge Liang and finally gained Cao Wei's world. Starting from Sima Yi, the power of the Cao family has been gradually weakened.

After Sima Shi came to power, he deposed the then emperor Cao Fang and established Cao Mao as the then puppet emperor. But unfortunately he died young. Then his younger brother Sima Zhao stepped onto the stage of history. This Sima Zhao was more vicious than Sima Shi, and he wanted to ascend the throne.

What Sima Zhao was thinking at that time was that since he had established a child as the emperor, why couldn't he be the emperor himself. Ever since he started having this idea, he couldn't stop it.

At that time, Cao Mao was not a fool. He was also a very capable person. He could tell that Sima Zhao was very impatient with him. In order to stabilize the throne, Cao Mao rewarded Sima Zhao with many things. But Sima Zhao didn't accept it, and Cao Mao knew that what he valued most was his throne, but this was something he couldn't bear. So Cao Mao summoned his ministers to discuss it. He said: Sima Zhao's heart is known to everyone on the road. We must kill Sima Zhao in order to live a good life.

But his ministers were not calm and felt that it was impossible to kill Sima Zhao, so they tried to persuade him one after another. Cao Mao led his 300 guards and maids to kill Sima Zhao. The final outcome was very sad. Simple, get killed.
