Cao Cao refused to proclaim himself emperor in order to avoid falling into political passivity. No one wants to think that his name is not justified, and the people's saliva can drown Cao Cao.
During the reign of Emperor Huan of the Han Dynasty, Cao Cao was called the Marquis of Feiting. It can be seen that Cao Cao's ancestors were Han ministers, Han people ate food, and were loyal to the Han Dynasty. It was also because of Cao Cao's shadow that his ancestors became officials. Therefore, the royal family of the Han Dynasty owed a large debt to the Cao family. Chinese people often say: "A drop of kindness will be repaid by a spring." If Cao Cao usurps the throne of the Han Dynasty, the whole world will not only scold him, but also his ancestors for eighteen generations! Logically speaking, others can usurp the throne, but he absolutely cannot.
In August 196, Cao Cao met with the Emperor of Xi'an of the Han Dynasty at Xudu and took control of the real power. Under the guidance of the Emperor, Cao Cao began the Crusades. He defeated Zhang Xiu, Lu Bu, Yuan Shu, and Yuan Shao, and finally unified the north. Cao Cao was politically enlightened, strengthening centralization and restraining local tycoons. The concept of family status was broken, and the middle and lower classes of the landlord class were placed in a higher position to curb power and strengthen centralization.

Cao Cao studied the art of war and had profound military theory. He has read the works of Sun Wu, Wu and other former military strategists. Cao Cao settled in the north and built water conservancy projects, which solved the problem of military food shortage and played a certain role in restoring agricultural production. Cao Cao loved poetry and the six arts. In the chaos of northern unification, attention was paid to the protection of the collection. Cao Cao himself was a famous poet. Cao Cao and his two sons Cao Pi and Cao Zhi were collectively known as the "Three Caos". So at that time, Cao Cao was not only capable, but also very capable, and could be said to be an all-rounder.
In 208, Cao Cao trained his army. In June, Cao Cao abolished the three kings, restored the prime minister system, and became the prime minister of the Han Dynasty. After basically pacifying the north, the front turned south. In preparation for the expedition to Jingzhou, Liu Biao and Wu Sunquan completely pacified the south. Therefore, in the Battle of Chibi, Cao Cao lost the opportunity to unify the south. At this moment, the three-party confrontation began. In 212 AD, the Xi'an Emperor of the Han Dynasty allowed Cao Cao to "visit Buming Temple, swords and shoes," as Han Dynasty Prime Minister Xiao He put it. Cao Cao was a powerful minister, but he did not usurp the throne until his death.
