Sun Wu, who was known as the "Saint of Soldiers" during the Spring and Autumn Period, described those who were good at fighting in his book "Sun Tzu's Art of War", saying: "Therefore, the victory of the good warrior is also, there is no strange victory, no wisdom name, no courageous merit", when he was fashionable and young and studying at home, Cao Cao, when he saw this passage, he wrote a sentence, which was far more famous than Sun Wu's original words, that is, "a good warrior, no outstanding merit".
This means that those who are really good at fighting and fighting will not have a particularly prominent reputation, because their victories all seem bland, and this blandness seems so natural and natural, without too much scheming. He hit it, and then he won, so much so that it was no surprise in the eyes of the world.
Friends who know something about the Three Kingdoms must have heard the saying ,'Guo Jia doesn't die, Wolong doesn't come out'". Wolong naturally spoke of Zhuge Liang, and Guo Jia was once the first strategist under Cao Cao, known as "Ghost Talent". Many people have such a view that if Guo Jia does not die, this Zhuge Liang does not dare to go out of the mountain, such a statement I do not agree with, but whether it is history or interpretation, guo Jia's death is indeed the time for Zhuge Liang to go out of the mountain
However, if the key to whether Zhuge Liang could go out of the mountain at this time was not someone else, it was his lord Liu Bei, if Liu Bei had not fled to the south and defected to this place in Jingzhou, it is estimated that Zhuge Liang's name would not have been heard of, and there would have been no matter of him going out of the mountain at that time. Behind cao Cao's many victorious battles, Guo Jia was guiding. In the second year of Jian'an (197), Cao Cao was defeated by Zhang Xiu, and Yuan Shao's side even wrote letters to humiliate him. Guo Jiawen thus put forward the famous "ten wins and ten defeats" theory.
It not only stabilized the military's morale, but also formulated a general strategic direction for Cao Cao. In addition, the destruction of Lü Bu, the collection of Liu Bei, the battle of Yuan Shao, the conquest of Wuhuan and other major historical cases are almost all planned by Guo Jia behind his back. It is no wonder that Cao Cao praised him for having seen people and being his own "Qizuo". Unfortunately, Guo Jiaying died early, and died of illness at the age of thirty-eight during Cao Cao's conquest of Karasuma. In 170, before Guo Jia died of illness, he said a last word, which was the last sentence of the ghost Guo Jia before his death, which can be described as a heartfelt word of repaying Cao Cao's kindness.
Guo Jia did not say anything about big strategic issues, but mentioned a key person. This person was none other than Sima Yi. Before his death, Guo Jia once said to Cao Cao, "If Sima Yi can use it, use it, and if he can't use it, kill it." Cao Cao was very hesitant to hear his words, and did not immediately get rid of Sima Yi, but believed that he had the ability to control Sima Yi, and that sima Yi was not enough to worry about in his lifetime. At that time, Sima Yi hid very deeply, and his heart was full of cunning and forbearance, and the Cao family could not see his ambition at all.
Sima Yi's founding time began with the guidance of Cao Pi, who, as Cao Pi's instructor, slowly gained the trust of the Cao family. After Cao Pi succeeded to the throne, the State of Wei had no one to use, so Cao Pi began to reuse Sima Yi, and Sima Yi's ambitions began to swell from that time and slowly exposed. So that the deposed emperor later ended the Cao family's hegemony, and the "three horses and the same slot" finally became a reality. Of course, this problem is not in Cao Cao himself, after all, whether it is Cao Cao or Cao Pi or even Cao Rui, they can control Sima Yi, but their life expectancy is too short, which gives Sima Yi the opportunity, if Cao Cao can take the most decisive measures, just like Guo Jia said to get rid of it, maybe things really won't happen.
