Cao Cao was the King of Wei in the State of Wei during the Three Kingdoms period, and as the most powerful dynasty in the Three Kingdoms period, Cao Cao made great contributions to the establishment of the State of Wei. Although Cao Cao was very powerful, he was able to establish the state of Wei, which was inseparable from his advisers. Later generations praised Cao Cao as "a capable minister who governs the world and a traitor to a chaotic world".
In the novel Romance of the Three Kingdoms, liu bei is praised and Cao Cao is belittled. However, after reading the Romance of the Three Kingdoms, the impression of Cao Cao will change. The reason why Cao Cao was able to unify the north was inseparable from his advisers, and secondly, Cao Cao was thirsty for talents and reused a large number of sages, and his men were full of talents.
The most famous strategist under Cao Cao was Guo Jia, who helped Cao Cao unify the north, and without Guo Jia's assistance, I am afraid that Cao Cao may not be able to unify the north. After Cao Cao unified the north, his State of Wei reached its peak. Guo Jia under Cao Cao was one of the most famous strategists, followed by Sima Yi.
In the late Wei dynasty, Sima Yi blocked Zhuge Liang's sixth exit from Qishan, and it should be known that Zhuge Liang in history was almost a figure close to the gods. However, Sima Yi was able to block Zhuge Liang's strategy, which shows that Sima Yi was by no means a simple person. However, Sima Yi's descendants usurped the throne and were despised by their descendants.
In fact, in addition to Sima Yi and Guo Jia, Cao Cao also had a very powerful strategist under him, and this person was Cheng Yu. Cheng Yu did not have such a sharp edge as Guo Jia and Sima Yi, but also had Guo Jia's talent and Sima Yi's longevity. In general, Cheng Yu is a combination of Guo Jia and Sima Yi.
No, Yu Yu should be the most mysterious strategist in the Three Kingdoms period. Cheng Yu is talented and famous. At that time, after Cao Cao knew Cheng Yu, he was thirsty for talents. Unexpectedly, as the most mysterious strategist of the Three Kingdoms, Cheng Yu actually took the initiative to join Cao Cao's command. But the history books record an even more shocking thing.
At that time, when Cao Cao first saw Cheng Yu, he said seven words: "Qingdang is my heart in the end." Cheng Yu was also very shocked after listening to it, and he felt that he was following the right person. Cheng Yu made a lot of achievements in the process of following Cao Cao, which at that time, allowed Cheng Yu to go to his peak.
In 239 AD, Cheng Yu was assigned to the Taimiao Temple, and sat on an equal footing with the great general Xiahou Huan and the great Sima Cao Ren. But Cheng Yu's personality is very admirable. He is upright, he is a public servant, and in the face of other people's gangs and factions, only Cheng Yu never forms parties for personal gain, which is very admirable.
Politically, Cheng Yu posed no threat to Cao Cao at all. At that time, Cao Cao went south to Jingzhou, Liu Chun surrendered, and the overall situation in the Central Plains was decided. At this time, Cao Cao sent a dark time to Cheng Yu, and at the same time, Cheng Yu also knew that he was going to retreat. After Cheng Yu retired, he stopped asking about political affairs and lived a pastoral life.
Cheng Yu's ability was not under Guo Jia, and Cao Cao asked Yu in many ways. After Cheng Yu retired, life was comfortable. In 220 AD, Cao Pi became emperor, and cheng Yu died that year at the age of eighty. Cao Pi was sad and distressed when he learned of the death of Cao Wei's founder.
