In the middle school textbooks, there is an article on Yang Xiu's death, from the above we can know that Yang Xiu is a very smart person, you can guess Cao Cao's thoughts, at that time Wei Guo in addition to Yang Xiu, there is a smart person who is almost the same as Yang Xiu, Sima Yi.
But later, in order to stabilize Jiangshan, Cao Cao found an excuse to kill Yang Xiu but did not kill Sima Yi.
Proud of yourself
In fact, before Yang Xiu was killed, he had offended Cao Cao many times because of his cleverness. For example, Cao Cao's bedside pastry, which he wrote "one crisp", was dismantled by Yang Xiu's self-righteous "one person and one bite of puff pastry" and distributed to the prince's ministers.
Of course, this is only a small thing, and Cao Cao will not kill because of a box of pastries
。 Yang Xiu thought through this matter that Cao Cao had not embarrassed him, and he was even more arrogant and arrogant, feeling that he was intelligent and intelligent, and Cao Cao was reluctant to kill himself. But the truth was the opposite, because Yang Xiu's arrogance and arrogance naturally did not get the favor of the emperor and the ministers, and over time, Cao Cao began to dislike him very much.
Sima Yi
On Sima Yi's side, his wisdom belongs to great wisdom, he is low-key and modest in his dealings with the world, knows how to hide his purpose and sharp edge, and will slowly achieve his purpose step by step, not at all ostentatious, such a person can be called a conspirator.
Yang Xiu and Sima Yi, a clever Zhang Yang, a smart low-key
。 Cao Cao also understood in his heart that these two kinds of people were actually more dangerous for Sima Yi, and if one of these two people went to rebel and seize his own Jiangshan, it must be Sima Yi. But Cao Cao killed Yang Xiu and left Sima Yi to the end, why?
Succession to the throne
In the end, it was still about the future succession of the throne, when Cao Cao planned to choose a son between Cao Pi and Cao Zhi, who could inherit the throne after his death.
However, he found that although Cao Zhi was very intelligent and very good in literature, he was not firm enough and was not interested in national politics, so he changed it to Cao Pi, and he was afraid that after his death, the two brothers would fight and kill each other, so he must weaken Cao Zhi's power and make him give up the idea of competing for the throne
。 Therefore, at that time, Yang Xiu, as a supporter of Cao Zhi, must be killed, otherwise after his death, a wise person like Yang Xiu would definitely encourage Cao Zhi to compete for the throne for his own interests.
Assisted by Cao Pi
Sima Yi was not killed, first, because he was very clever, and second, he was a supporter of Cao Pi, no matter what he wanted, at least he was willing to assist Cao Pi. Cao Pi needed Sima Yi's guidance in many ways, especially in the situation where the Three Kingdoms were at its peak at that time, and if Cao Pi did not have a person around him who could support him, the State of Wei would definitely be destroyed by Wu and Shu.
Therefore, after Cao Cao's death, for the sake of the Wei state of Jiangshan Sheji, although he felt that he was a dangerous person, he still left him.
