If you look at the romance of the Three Kingdoms, you are a traitor, but if you look at the history of the Three Kingdoms, that is another matter. If Cao Cao unified the world and created a prosperous time, he would be a worthy hero, such as Emperor Wen of Sui Dynasty who usurped the Northern Zhou Dynasty and Zhao Kuangyin who usurped the Later Zhou Dynasty. Unfortunately, princes would rather have seeds. It's true. Why does the world belong to the Liu family? Liu has lost his virtue for a hundred years, and it is time to be a wise master. It's a pity that a fire broke out in Chibi. Look at the many warlords in the Three Kingdoms. Sun Quan was unkind and ungrateful, but he could not clean up a Wu Dong, nor could he move northward. Liu Bei was down and out, accounting for a profit, and there were many major generals. All the energy he finally accumulated was lost in Yiling, and the rest was exhausted by Zhuge Liang's Northern Expedition. Yuan Shao, before him, was resourceful, but never broken. I only know that the scholar-officials don't know the king, and even their sons can't manage well. Youzhou Gongsun Zan is brave and not the material for governing the country. Marten is cool in the west, even the northwest can't decide. Ma Chao is brave, but he is an immoral master (Ma Teng's death is Ma Chao's fault). He is arrogant and brave, not the only one who can win the trust of the world. Liu Biao said nothing. He failed his reputation. Ada and Liu Zhang and his son lived together, but the Hanzhong portal was occupied by Zhang Lu, and the western Shu was undecided, so it could not be used. People like Zhang Xiu can't say, either they occupy a city, or they lead troops to get together as bandits. They are really not heroes, they all make a living in troubled times.
On regional talents, Cao Cao comes first. These are not heroes. When Cao Cao stayed in Chen, he begged Lu Bu to have no food, so he took the people as rations. This cannot be evaluated. However, Cao Cao retained the vitality of the Han people in the north, and the warlords fought and mourned everywhere. Although he has done some activities to kill cities, he is still clearly aware of the harm caused by the war to the people. For example, he wrote "The Travels of Haoli", and he also prohibited the destruction of other people's grain fields. He took many measures to develop Wei's economy and people's livelihood. His Yu Xun is a genius in Wang Zuo and a first-class master in internal affairs.
Three points in the world, 70% for Wei, 20% for Wu and 10% for Shu.
Guo Moruo, Lu Xun and others all admire Cao Cao. For example, in Wang Zhaojun written by Guo Moruo, there is a passage saying that all people are called Prime Minister Cao.
The face of history has long been changed beyond recognition, but The Romance of the Three Kingdoms is the most incredible. It is a novel and a historical framework.
In any case, Cao Cao is a successful politician and is called a great statesman and strategist in history textbooks.
