What did Sima Yi say before he died that made Si Mazhao afraid to proclaim himself emperor?

After Sima Yi launched the change of Gao Pingling, Cao Cao's power has basically been completely eradicated. It is also a matter of wanting to be an emperor too much. However, Sima Yi promised that Cao Pi would only be a Chen Wei in this life, so he never claimed to be the emperor until his death. This is somewhat similar to Cao Cao's practice, and both of them have the same concerns. However, neither of Sima Yi's sons said such a thing. Why didn't Sima Shi and Si Mazhao proclaim themselves emperors? Especially Si Mazhao's ambitious Dalin Sima Yi was ashamed, but it was Sima Yi's last words that made Si Mazhao give up the idea of being an emperor. What did Sima Yi say before she died?

Sima Yi has always been a forbearing person. When Cao Cao unified the Central Plains, Sima Yi remained dormant. Even so, Sima Yi's talent was noticed by Cao Cao. Guo Jia, the first counselor of Cao Cao, asked Cao Cao to kill Sima Yi before he died. But Sima Yi acted cautiously and never gave Cao Cao a chance to get rid of him. After Cao Pi ascended the throne, Sima Yi began to show his talents. With the help of Sima Yi, Wei became rich. It laid the foundation for the reunification of the three countries in the future. During the reign of Cao Rui, Sima Yi was suppressed by Cao Shuang and other Cao Shi clansmen. However, Sima Yi did not strike back, but tolerated again and again. Everything he did was waiting for an opportunity, an opportunity to change Sima's fate.

In 249 A.D., ICY, the young master, went out to worship the first emperor in the imperial city, and Sima Yi staged a coup in Gao Ping Ling, destroying Cao Shuang forces in one fell swoop and taking control of the actual regime of Cao Wei. Since then, the Cao Wei regime has fallen into the hands of Sima Yi.

After Sima Yi's death, State affairs were held by Sima Shi and Si Mazhao. Both Sima Shi and Si Mazhao have ambitions, especially Si Mazhao. After taking control of Cao Wei's regime, he can do whatever he wants. However, Sima Shi and Si Mazhao never proclaimed themselves emperors. Why?

It turns out that this has something to do with Sima Yi's last words. Sima Yi told Si Mazhao before he died: "You two are good at managing state affairs and helping the emperor pacify Kyushu. Be careful! Be careful! " Especially the last two "cautious", Sima Yi said twice in a row. It is not difficult to understand that Sima Yi, who was cautious by nature, said such last words before he died. So what did Sima Yi make Si Mazhao cautious?

In my opinion, Sima Yi made Si Mazhao cautious for two reasons. One is prudence, which is one of the main reasons why Sima Yi can win the world. No matter when he is careful, he must not be careless. Second, Sima Yi made Si Mazhao cautiously proclaimed himself emperor. At that time, many people still took refuge in Cao Wei, and it was not the time to be the emperor. Therefore, Sima Yi asked Si Mazhao to be cautious. Because of this, Si Mazhao did not dare to proclaim himself emperor until his death.
