Cao Cao of the Three Kingdoms
At the end of the Eastern Han Dynasty, it was an era of flames and heroes, and Cao Cao was like a unique piece of jade, shining in the torrent of history. He is not only the embodiment of wisdom, but also the representative of heroics, talented and ambitious, and has become a legendary figure with constant controversy in later generations. 
Cao Cao, he is like a cunning fox, witty and treacherous, on the one hand he is bold and generous, on the other hand he is ruthless. He was an outstanding military strategist, strategizing and winning thousands of miles away; He was also a brilliant politician and poet, and his pen was full of flowers and fine words. His thirst for talent and courtesy have made countless talents bend their waists; And his sentence "I'd rather teach me to bear the world, and stop teaching the world to bear me" is even more respectful. However, this hero, who covered the sky with one hand, has never been able to usurp the Han and establish himself as the emperor. Why is that? First of all, Cao Cao attached great importance to his reputation. He knew that once he became the emperor, he would be infamous through the ages and become a usurper. He cherishes his feathers and does not want to leave a stain on history. Second, Cao Cao possessed extraordinary political wisdom. He judged the situation, weighed the pros and cons, and knew that the situation was complicated at that time. Although they hold great power, the power of Sun Quan and Liu Bei should not be underestimated. Therefore, he chose to be patient and wait for the time to come. Moreover, Cao Cao was a pragmatic person. He is more focused on actual power than on illusory thrones. In his opinion, having real power to control the world is far more important than having an empty throne. He understands that he can't have it both ways, so he focuses on the actual grasp of power. Cao Cao's choice not only demonstrated his political wisdom, but also demonstrated his pragmatic spirit. This spirit allowed him to gain a foothold in troubled times, and eventually achieved great things. His forces were mainly concentrated in the north, with Sun Quan in the south and Liu Bei in Western Shu hanging above his head like two sharp swords. Cao Cao understood that in order to secure the country, he must eradicate these threats and achieve the unification of the world. Therefore, he set his sights on the further future, not only to become emperor, but also to establish a stable and long-lasting regime. Cao Cao's pragmatic spirit is reflected in his emphasis on talent. He recruits talents, does not stick to one pattern, and only looks at ability. This way of employing people made his power grow rapidly and laid a solid foundation for his future career. At the same time, he also paid attention to domestic reforms, reducing taxes and resuming agricultural production, so that the people could recuperate and recuperate, and won the hearts and minds of the people. In military affairs, he was good at using troops, flexible and changeable tactics, and became a generation of military strategists
To sum up, there are many reasons why Cao Cao did not become emperor: personal morality, political wisdom, pragmatism, and accurate grasp of the situation. His choice not only left a deep historical mark on future generations, but also provided us with an example of political wisdom, strategic vision and pragmatism. Cao Cao's life is full of legends, and his story inspires us to keep a clear head, be firm in our convictions, and put them into practice in the face of complex situations.
