The dying words of Han Xian Emperor Liu Xie reminded us that after experiencing the control of Dong Zhuo, Wang Yun, etc., Cao Cao's "hijacking the emperor to order the princes" came. "The bustle in the world is all for benefit; the hustle and bustle in the world is all for benefit." It was the dying words of Emperor Xian of the Han Dynasty that revealed the world's pursuit of fame and fortune, and his heart was naturally as clear as a mirror to the treacherous and loyal ministers.
Liu Bei proclaimed himself emperor in 221 AD. He claimed that he helped the Han Dynasty and had many followers for a while. Naturally, Liu Bei's rise was very rapid, while Sun Quan did not proclaim himself emperor until 229 AD. When Emperor Xian of the Han Dynasty saw Liu Bei and Sun Quan proclaimed themselves emperors, he looked up to the sky with great emotion and laughed. On the contrary, Cao Cao has never sat on the position of emperor in his life, and becoming emperor does not seem to be that desirable to him.
In fact, Cao Cao was considered a semi-loyal minister, and he was considered "courteous" to Emperor Xian of the Han Dynasty throughout his life. When he was alive, he never coveted the title of emperor of the world, but it was a fact that he "held the emperor hostage to order the princes". On the contrary, it was Liu Bei and Sun Quan who came to attack Cao Cao from the highest point of morality, euphemistically called "eliminating the Han traitors". They are really on the road to becoming emperor, and let the title of rebellious minister be placed on their shoulders. On the other hand, Cao Cao is more like a treacherous minister, someone who hides behind the emperor and gives orders.
In fact, the three of them are just for their own interests. Cao Cao does not have a name recognized by the world. Rebellion is the last "shame" to truly become emperor. Some people say that Emperor Xian of the Han Dynasty had already abdicated the throne at that time, and their proclaiming the emperor was not considered disloyal. But it is true that Emperor Xian of the Han Dynasty is still alive, and it is not that there is no royal bloodline anymore. The fact that Emperor Xian of the Han Dynasty is still alive is a deterrent to them. From ancient times to the present, if you want to establish yourself as an emperor, you need to be justified.
