What are the bad things Zhuge did in the official history of the Three Kingdoms?

I can tell you very clearly that Zhuge Liang is indeed not as powerful as the interpretation and writing, but he can be said to be the true "dedicated person, dedicated to death", even if he is there, it is for Shu Han! Regarding Zhuge Liang’s questions, let me answer them one by one. . . . .

1. Indirectly killed Guan Yu. Some people think that Zhuge Liang withheld the information and kept it secret. This is nonsense. Guan Yu went from being imprisoned and beheading Pang De to defeating Maicheng in just an instant. Before, Guan Yu had been receiving good news. No one could have expected that he would die, and there was no preparation at all. Furthermore, the transportation at that time was not that fast to Chengdu, and Zhuge Liang had not entered the core department of the military. So Guan Yu has nothing to do with Zhuge Liang.

2. "Greed for power." Zhuge Liang took over the power of the Shu Han after Liu Bei's death, under one person and over ten thousand people. He did not give the successor the power, which caused later generations to think that he was greedy for power. In fact, this was not the case. After Liu Bei's defeat at Yiling, the Shu Han suffered from internal and external troubles. , has been a troubled time. Yiling was defeated, and the country's power was greatly damaged; the monarch was newly dead, and people's hearts were not yet stable; there was chaos in the south, and the war was on the rise. If Zhuge Liang hands over power to his later master, Shu will surely perish; if he hands over power to Li Yan, Yizhou's power will rise and the regime will be overthrown. Zhuge Liang had to take over all the power!

3. Destroy Li Yan. In this case, many people used Zhuge Liang to eliminate dissidents and abolish Li Yan. Not really. Li Yan was also the minister of Tuogu, but his performance was too unqualified. He was supposed to be stationed in Yong'an, but he secretly left Chen to guard alone. He stationed himself in Jiangzhou, built a big city there, and asked to open a government to manage affairs. Li Yan himself made a mistake. The purpose of Liu Bei asking him to be the Tuogu Minister was to use Li Yan's Yizhou people to stabilize the power of Yizhou, but Li Yan's approach made the power of Yizhou rise (Li Yan did not understand the holy intention). Zhuge Liang repeatedly tolerated it, and finally Li Yan let go of a low-level mistake (Li Yan's case is still a mystery, so I won't go into details here). Zhuge Liang always enforced the law strictly and crippled him (rather than killed him).

4. Do not reuse Wei Yan. Wei Yan, as the most capable general in the Zhuge era of the Shu Han Dynasty and a favorite of the late emperor, was not reused by Zhuge Liang, which puzzled future generations. In fact, it was because Wei Yan was too powerful and capable that he was not reused. After Liu Bei's death, Jingzhou was lost, which meant that Zhuge Liang's Longzhong strategy could no longer be realized. Zhuge Liang knew that it was impossible to regain the Han Dynasty. He could only defend the current land in Shu and live up to the late emperor's three wishes. However, when Yizhou was tired and troubled, Zhuge Liang discovered the subtle changes within Yizhou. He chose to use defense as offense, use war to gather people's hearts and protect Yizhou. But Wei Yan was too strong, and Zhuge Liang knew that using him would expand the war and disrupt his own national policy. Even when he died, Zhuge Liang was still worried about Wei Yan, fearing that his strength would lead to the destruction of Shu Han, so he induced him to rebel and dragged him to be buried with him. (Wei Yan's rebellion is also a mystery. Zhuge Liang must have prepared for his death. The above is just a personal opinion)

In short, Zhuge Liang is truly "dedicated to death"!
