First of all, Cao Cao has the reputation of "holding the emperor's hand to command the princes", so I want to correct his name first. Looking at what happened at that time, at the end of the Eastern Han Dynasty, the Yellow Turban Rebellion caused chaos in the world. The first, Dong Zhuo, mobilized all the troops in Xiliang and was ordered to go to the capital. He put down the rebellion of the Shichangshi and gained the advantage of holding the emperor hostage and commanding the princes. At that time, Dong Zhuo was powerful and full of power, but he eventually died at the hands of a slave with three surnames. With Lu Bu's bravery and military prowess, he could unify the world. But in the end, he fell into Wang Yun's beauty trap and became a Diao Chan with two different bodies and heads, making the world laugh! Looking at Cao Gong again, he went down to Pi City to capture Lu Bu. Lu Bu died in the Baimen Tower. At that time, Liu Bei was the one who offered a plan to kill Lu Bu. It is true that Lu Bu was greedy for money, lustful and had no faith at all, but he was also kind to him by shooting a halberd at the gate to relieve the bloody disaster of his soldiers. Liu Bei's counterattack to his death may be closely related to Lu Bu's capture of Xuzhou, which shows that this person is narrow-minded and takes advantage of others' power. According to my own inference, Cao Cao wanted to save Lu Bu's life at that time, just as he later saved Guan Yunchang. From this, it can be seen that Cao Cao cherished talents. Just as Cao Cao did not kill Zhang Liao at that time, he accepted the advice that "a thousand troops are easy to get, but a general is hard to find". Why Cao Cao got the reputation of "holding the emperor to order the princes" is actually consistent with China's Confucian culture. Whether it is ancient China or modern China, there are always orthodox ideas deep in the hearts of the Chinese people. The emperor of the Han Dynasty killed the snake and revolted, destroyed the Qin Dynasty and established the Western Han Dynasty. Isn't this also a "rebellion"? Ignorant common people will not think about it. If a society wants to develop, good things must destroy bad things. This is an unbreakable historical law. Of course, my current point of view is that of modern people. The ancients had the limitations of their times, and Luo Guanzhong certainly could not get rid of them. We cannot force them, but people born in modern times cannot follow others' opinions. Therefore, whenever I hear people nowadays talking about Cao Cao, they always directly copy Luo Guanzhong's views, which is really sad. The main reason why people are human is that they have their own sound brains, can have their own rules for being a human being, and can distinguish right from wrong, otherwise they are no different from animals!
