Li Yan, who was appointed by Liu Bei as the minister of Tuogu, and Zhuge Liang, who was also the min

Because after Liu Bei's death,Li Yan did not assist Liu Chan wellMoreover, one mountain does not tolerate two tigers, and Li Yan and Zhuge Liang are also fighting openly and secretly。But Zhuge Liang was dedicated to the sake of the court. And at that time, Liu Bei didn't really trust Li Yan when he was alone, but just wanted to use Li Yan to suppress some forces.

At that time, when Liu Bei died,designed a subordinate structure of Liang Zheng Yan and Deputy Governor, that is, Zhuge Liang is Zheng and Li Yan is the deputy。Li Yan was in charge of the army, and gave him the position of protector of the central capital, and let him take charge of all the armies inside and outside. Later, after Liu Bei's death, some people rebelled, and Li Yan was the protector of the central capital, but at first Liu Bei arranged for him to guard Yong'an.

Therefore, he wanted to use the army to quell the chaos, but he could not leave Yong'an, because he was afraid that other countries would take advantage of it. Although he has the responsibility of protecting the central capital, if he does not return to Chengdu, he will not be able to exercise his rights, and the command of the army can only be handed over to Zhuge Liang.

Later, when Zhuge Liang was on the 4th Northern Expedition. It was Li Yan who was in charge of the army's food, grass and military supplies, but the weather was not beautiful, just in time for several days of heavy rain. There was no way to send grain and grass to the front line as scheduled.

Li Yan asked people to send a message to Zhuge Liang and told him to withdraw the army. Zhuge Liang also listened to Li Yan's words.

After Zhuge Liang and the others retreated, Li Yan reversed his word again, and said in a strange way, there is a lot of grain and grass, so why should he return. He also played to Liu Chan, saying that Zhuge Liang was advancing by retreating, and his purpose was to lure thieves and fight, which was obviously slander, so Zhuge Liang showed Liu Chan the letter that Li Yan asked him to withdraw from the army to him. At this point, Li Yan could only plead guilty in the end, and he was finally deposed and exiled.

Li Yan only wanted to gain greater power, and he did not sincerely assist Liu Chan, so Zhuge Liang insisted on abolishing him.

Because Liu Bei knew the person entrusted by Li Yanfei at that time, he chose Zhuge Liang to join him and let Zhuge Liang get rid of this heart disease for himself.

The statement of "Romance of the Three Kingdoms" is that Li Yan wants to shirk his responsibility (the responsibility of not doing it) and blame others (the sorrow of showing not to advance).

Because Li Yan is not a reliable person and cannot take on this great responsibility, Zhuge Liang wants to abolish him.

I think that Li Yan at that time really didn't have that much ability, and he wasn't as capable as Zhao Yun, so I wanted to abolish him.

Because Zhuge Liang's talent and strategy are very outstanding, he belongs to the best among the strategists, and although Li Yan is very capable, he does not have Zhuge Liang's talent and prestige.

Because Li Yan made a big mistake, for example, the situation of transporting grain was not particularly good, he asked Zhuge Liang to withdraw from the army, and later said that the military food was sufficient after retiring, which angered Zhuge Liang.

Zhuge Liang is the prime minister, Li Yan is at best the commander-in-chief of the front line, and Li Yan must be agreed by Zhuge Liang if he wants to mobilize the army.

Because he wants Zhuge Liang and Li Yan to complement each other, if he assigns this task to one person, it may make one person more stressed.

It was because Liu Bei felt that Zhuge Liang alone might not be able to do anything, and he would not be able to assist Liu Chan, because he knew that his son did not like to listen to others.

He has the power to balance Zhuge Liang, because Liu Bei gave Li Yan the right to serve before he died, so he can balance Zhuge Liang.

Personally, I think that Li Yan is Liu Bei's real object of entrustment, because Liu Bei handed over the military power of Shu Han to Li Yan, which is very important, so I feel that Li Yan is Liu Bei's real object of entrustment.

Zhuge Liang, because Shu Han did not have Zhuge Liang, it could not last that long at all, and the relationship between Zhuge Liang and Liu Bei was also better.

Because Li Yan's two faces ran to separate Liu Bei and Zhuge Liang, maliciously admonished and spread rumors, and blamed Zhuge Liang for the retreat due to lack of food and grass, and was finally found and wasted.
