Not Cao Cao, but the son of the eunuch's adopted son. He was born in a bad family, but his father was a senior official at that time, Qiu, the nominal commander-in-chief of the three armed forces, Cao Cao, and he was a man with a great political mind. He didn't usurp Han, not because he was incompetent, but for many reasons. Later, he was regarded as the real ruler. The reason why Cao Cao didn't stand on his own feet was that he didn't have the title of "emperor", which actually had a lot to do with his personality. When he first started out, he didn't have any great ambitions. His "relying on the emperor to make the princes" is nothing more than a political and military means to complete the reunification of the motherland and put an end to ethnic division. At that time, he didn't "hold the emperor to make the princes", that was Yuan Shao, and maybe there were others. Look at that time, besides Cao Cao, who else had the ability to achieve Cao Cao's later achievements? It can be said that his achievements and chassis are all played by himself.

The reasons for Cao's failure to unify are as follows

A Cao Cao's personality reasons

Cao Cao's personality is perverse, and Cao Cao loves talents like life. He is a corporal who also has obvious shortcomings and advantages. He is a bit horny, moody and suspicious, and regards human life like dirt. All this makes it difficult for him to become the unified master of the world. Cao Cao often deviated from the right track and acted according to his own likes and dislikes, killing people in his dreams, drinking alcohol and killing concubines at will. Killing Kong Rong and Yang Xiu, including killing hundreds of thousands of innocent people in a rage, is not what a hero should do, but more like a ranger. So his personality inevitably influenced his decision-making. This has a great influence on his great cause of reunification.

Second, Cao Cao lost the hearts of the people.

After defeating 50 thousand and pacifying Liaodong, Cao Cao's strength and prestige reached a peak. It turns out that Cao Cao appeared as a minister of ZTE in the Eastern Han Dynasty. He "held the emperor to make the princes" and "held the emperor to make the princes". Cao Cao originally stood on the side of justice, hanged the people and fought against the princes, which was different from the previous powerful ministers He Jin, Dong Zhuo and Yuan Shao. So Cao Cao won the hearts of the people. However, Cao Cao conquered half of China by force, especially after acquiring the richest and most core area in China at that time. Just after Cao Cao occupied Yecheng, his ambition expanded, and he overhauled civil engineering, such as the bronze sparrow terrace, for his own enjoyment, and then he became the prime minister and ran rampant in the ruling and opposition parties. In the Romance of the Three Kingdoms, it is recorded that Cao Cao has no son of heaven and often deceives you. On one occasion, he even "covered himself in front of the son of heaven to meet him" and "provoked Master Guan to kill him with a knife". Although it is a romance, it also reflects some facts at that time.

(3) Failure to train commander-in-chief talents

Since Cao Cao made his fortune in Yanzhou, almost all battles have been commanded by him and rarely handed over to others, which directly led to the fact that many of his generals, though brave, are not marshals. Only one commander-in-chief is busy in the east and west. How can he be too busy to rule the country? Facts have proved that Cao Cao's subordinates, such as Xia and Zhang Liao, are all commander-in-chief talents, but Cao Cao didn't give them a chance to play.

4. Economic reasons

Economically, the focus of the traditional small-scale peasant economy is still in the north, but the commodity economy gradually shifted to the south with the population migration of the three countries, and the economic strength of Cao Wei was weakened. Although it is strong on the whole, it is inevitable, and Wu Shu's economic strength is constantly increasing, thus ensuring its national strength against Cao Wei's invasion to the south.

5. Political reasons

After Cao Cao, the eunuch, although his family was rich, he claimed to be the descendant of Cao Can, the founding father of the Han Dynasty, but in fact his reputation was far less than that of Yuan Jia, the "Four Kingdoms", or even the fourth Qiu Yangjia. At the end of the Eastern Han Dynasty, when the family thought was very strong, it was difficult to get the support of literati and aristocratic families. Therefore, although Cao Cao is strong in force, his political foundation is not solid. This is one of his fatal injuries.

6. Military reasons

Militarily, although Cao Wei had the largest and strongest army, it fought on two fronts, with nomadic people in the north and Wu Shu in the south, and Wu Shu occupied the geographical advantage. Under the leadership of Sun Quan and Liu Bei, Cao Wei did not dare to underestimate the overall military strength. Before Cao Cao's death, China was not completely in a stable state in the later period. Besides Sun Liu, there were governors such as Ma Chao, Han Sui, Liu Biao, Liu Zhang and Zhang Lu. Talent mobility is great, and these governors are not inferior to Cao Cao in talent soft power, and sometimes even catch each other and kill each other. Although Cao Cao's soldiers are skilled and versatile, he is also short of money.
