1. I experienced Dong Zhuo's rebellion with my family when I was young, and I was educated by Confucianism since I was a child. My family has inherited the art of war (Sima Art of War is the experience summed up from numerous military failures). When he was young, Zhao Hu, a powerful mentor, was jealous of their intimate relationship and almost killed him. The unstable childhood life made young Sima Yi mature. At an early age, he understood the hardships and intrigues of life, and created a mature and steady character of forbearing and waiting for orders.
2. Sima Yi's utilization of resources and his understanding of himself are higher than those of his peers, which is reflected in his philosophy of life. Far-sighted, cautious, will not be carried away by immediate success, nor will they feel sorry for themselves because of adversity.
3. There is a view that Sima Yi objectively killed three ancestors of Cao family, which is good. My opinion is slightly different. Sima Yi is not a god. He doesn't know when Cao Jiazu's Sun San generation will die. He is a pragmatic long-term strategist. Not only in politics and military, but also in life planning.
Choose working methods according to the different personalities of Cao Shi's leaders. The last three generations of leaders were very satisfied with him. Even though they trusted Sima Yi more or less, Sima Yi, who acted wisely, had no reason not to use him, let alone kill him.
4. Keep a cool head in adversity, make full use of resources, coordinate interpersonal relationships, handle contradictions reasonably, and make work plans. There is a saying from Sima Yi in the "Military Division Alliance", "Along the way, there are no enemies, only teachers." It is precisely because of this understanding that Sima Yi can judge the situation calmly, come up with the best plan and implement it unswervingly. If his eyes are full of enemies, how can he sober himself up? We should know that it is hard to bear unimaginable psychological pressure to treat people around us as enemies at all times, and emotional expression is anxiety and excitement. This mentality can only make things worse and worse.
For example, in the face of Zhuge Liang's Northern Expedition and Cao Zhen's death, Sima Yi replaced Cao Zhen to fight against the invasion of Western Shu. There are several problems on his face. First, soldiers didn't bring them out by themselves, so they need to know each other. Second, the differences between generals in strategic and tactical deployment have no prestige and are not easy to convince the public; Third, the central leaders' incomplete trust in themselves; Fourth, based on incomplete trust in leaders, the state has limited decentralization.
Compared with the military and political power of Prime Minister Zhuge, Sima Yi is very passive in exercising power at arm's length, the absolute tacit understanding between generals and soldiers trained for many years, and the great advantage of supporting national military activities. In the end, Sima Yi persisted in winning with a positive attitude and extraordinary wisdom, which brought a turning point in life, from passivity to initiative.
5. Years of political passivity must be tolerated. Although it is a tough character and strong psychological quality is the solid support behind it, such long-term depression is also the accumulation process of negative emotions. When Cao Fang succeeded to the throne and Sima Yi survived, I think Sima Yi's mentality at that time was still in the best period of Fuzheng, from dangerous beach to smooth sailing. At that time, few people really wanted to kill Sima Yi, so the etiquette of supporting politics was almost the peak of Sima Yi's life at that time.
Sometimes it is necessary to believe in fate. Sima Yi and Cao Shuang lived in peace at the beginning of Fuzheng, and the balance of power was broken by Cao Shuang. I have my own opinion on whether Cao Shuang killed Sima Yi. Cao Shuang sent someone to visit Sima Yi's illness. After confirming that Sima Yi was still alive, he thought there was no threat, so he didn't kill him, not because Cao Shuang was kind. Although Sima Yi withdrew from the center of power, he still has popular support. Sima yi is still in the old military region below. Sima yi has been respected in the DPRK for decades, and the foundation of ministers is still there.
Sima Yi's performance was so perfect that Cao Shuang couldn't find a reason to kill him, not because he didn't have the heart to kill him. This can be seen from Cao Shuang's means of overhead Sima Yi's power.
Sima yi is thinking about the fate of Sima Jia behind him at this time, let nature take its course? Fear that in his later years, Cao Shuang came to power, not necessarily because he or his family made some mistakes that might lead to death. Even if Cao Shuang doesn't commit suicide, then after one hundred years, the Sima family is likely to recover. What's the value of enduring it for so many years? So we must seize power.
The event of Gao Ping Ling was the way for Sima Yi to seize power, and after Gao Ping Ling, Sima Yi's repressed spirit was released. Therefore, compared with the past, Sima Yi's ruthless and violent attitude is quite different from his previous moderate and humble attitude. Sima Yi, who has witnessed so many power struggles and intrigues, wants to kill all threats to himself and his family. Not only that, but he can't be stable and practical. This is the sorrow of the powerful minister and the honor of the powerful minister!
If we put down many titles such as Sima Yi's militarist, strategist and politician, and treat Sima Yi's life as an ordinary successful person around us, you will find that Sima Yi is nothing more than an ordinary person with flesh and blood, and his life track is reasonable. He is not a saint, he has his own life and work, and he also has a good and evil side. When you are kind, build water conservancy projects and reform farmland, which objectively benefits the people and is conducive to national construction. When fierce, blood is easy to kill, mistakes will be reported, and political enemies are ruthless.
Let's take a look at Sima Yi in the Military League. That's what I was told, stripping away those glamorous titles. Sima Yi stood before us alive. History is the history of mankind, and Sima Yi's history is his observation report and clinical research record. There is nothing good or bad, loyalty and betrayal, only our thinking about life, that's all.
All the above are personal opinions. Let's express our opinions, seek common ground while reserving differences and discuss together.
