Speaking of the courtiers entrusted to orphans, Sima Yi was the most famous courtiers in the Three Kingdoms period. After Cao Rui's death, Sima Yi and Cao Shuang were left to help Cao Fang. First of all, Cao Shuang's autocratic power caused great losses to Wei. Then infighting continued, Sima Yi killed Cao Shuang, and finally Sima Yi took Wei, but Zhuge Liang's nephew Zhuge Ke was not a simple advocate. After Sun Quan's death, Zhuge Ke was left as an orphan, and Zhuge Ke became an orphan.
In fact, the Eastern Han Dynasty was a dynasty in which consorts and eunuchs took turns to be autocratic, and the demise of the Western Han Dynasty was Wang Mang's arbitrariness. To this end, Liu Bei had to guard against what kind of person his son was. As a father, of course, it is clear that Liu Bei not only arranged Zhuge Liang to be an orphan, but also arranged Li Yan to be an orphan and * * * assisted Liu Chan.
Liu Bei's arrangement is: Zhuge Liang is in command, assisting Liu Chan in handling state affairs but not mastering military power; Li Yan is in charge of the military power of Yong 'an, the important town, and is responsible for the defense of the eastern Shu Han land; Li Yan and Zhuge Liang contain each other inside and outside; It is enough to have Wei Yan guarding Hanzhong in the north!
In addition, Zhuge Liang's army is backed by Jingzhou. As an outsider, its foundation in Yizhou is naturally unstable. Li Yan is not only from Jingzhou, but also entered Yizhou very early. He has a natural connection with the local family in Yizhou, and also has a certain connection with the former Jingzhou Army. The choice of these two people is also based on the consideration of stabilizing the regime.
With the gradual stability of Shu and Han, the power struggle between Shu and Han became fierce. Before the Northern Expedition, Zhuge Liang used various tricks to weaken Li Yan's influence except the Southern Expedition. Finally, it was broadcast before the lifting of the ban on the Northern Expedition, and Li Yan's mistakes in the Northern Expedition were discovered. He hit it to the end with a stick, and it took him eight years to completely eliminate the cause left by Liu Bei!
