In fact, the most obvious feature of the three countries is that it is safest to hold military power in your own hands. After all, in troubled times, if we can have our own army, it's like chickens laying eggs and eggs laying chickens. Marching to fight and developing our own battlefield cannot be separated from the support of our own army. At the same time, if your army is in your own hands, you can always protect your thoughtfulness. When Cao Cao made his debut, his troops were still few, and there were thousands of people in the team. It was very convenient to command the team in his own hands. In other words, for such a small person, it is enough to lead troops to fight when fighting, and Cao Cao's military strength is also outstanding. Cao Cao fought almost by himself in the process of unifying the north. Therefore, Cao Cao's early choice of his soldiers is also reasonable. Although Cao Cao was surrounded by Xiahou Che, the first general of Cao Wei, and Jiang Yang. But not many people can choose to be alone. Small battles may come out to resist once. However, if there is a Sino-Korean war or the same Guandu war, Cao Cao himself will not feel at ease. Moreover, if there is an emergency in the war, the process of conveying and giving orders before and after is itself a very troublesome thing.
Another reason is the system with one person, not the soldiers in the Three Kingdoms. Just like Liu Bei cheated Cao Cao's war horse, in the process beyond Cao Cao's control, these 50 thousand war horses directly entered Liu Bei's command. Therefore, not all the soldiers in the Three Kingdoms follow their masters. Then Cao Cao received a very dangerous signal. In other words, if the subordinate generals mutiny, their losses will be infinite. At the same time, it also brought huge losses to itself. In fact, Cao can't help it. I am the best on the border of the Three Kingdoms, but I have a very picky emperor on my head. It can be said that Han Xianzhi did not always count Cao Cao, but made great efforts to eliminate Cao Cao's selfishness. But everything that threatened him was cleaned up by Cao Cao. But there is still adultery. Shunde is one of them, and he has always been bitter about Cao Cao's later meeting with Wang Wei. It can be said that in the process of Cao Cao reaching the peak of power, there were constant voices of opposition around him, and many capable people fled after seeing Cao Cao's face. You choose the reputation of the Chinese constitution that you like.
There are so many people in the court who are against it. Cao Cao said that if he stayed in Hutu all day, these people would kill him sooner or later. Then, if you hold the military power in your own hands and can lead your own army in case of war, that is the greatest guarantee for your own safety. (william shakespeare's Hamlet and War) Moreover, in the event of a war, Cao Cao has enough ability to mobilize the army, and he can issue a notice to ensure the effective operation of the army, whether attacking or retreating. In fact, Cao Cao chose his own conscription action entirely for personal reasons. For their own safety, surrounded by soldiers to protect, much safer than Xuchang. Xuchang is also known as Cao Cao's territory, but it's easy to avoid backstabbing with an open gun. At the same time, Cao Cao also has his own grand goals. That is a dream of a unified world. Although it has not been realized, people who value their career will directly lead troops to fight, which will not only improve morale, but also better carry out the war.
