Liu Bei believed that Cao Cao was a thief and that Cao Wei usurped the land of the Han Dynasty and detained the emperor of the Han Dynasty. The reason is very simple, because Cao Wei is not surnamed Liu, but Cao. Since Liu Bangbai took the oath, the emperor of the Han Dynasty has been surnamed Liu. Even if there is an absurd thing in the middle, it will soon be replaced by Liu Xiu, so Liu Bei thinks Cao Cao is a thief. Liu Bei's political slogan is to revive the Han Dynasty. Born in the Han Dynasty, Liu Bei has always claimed to be a relative of the Han Dynasty. At the same time, his lifelong pursuit is to rebuild the Han Dynasty. Although Liu Bei finally proclaimed himself emperor, it was only after Cao Pi usurped the throne that Liu Bei proclaimed himself emperor in order to continue the legal system of the Han Dynasty. Liu Bei's country name is still "Han". When Liu Bei established the Han regime, all the emperors of the Han Dynasty were enshrined, which theoretically continued the incense of the Han Dynasty.
Cao Cao thought that Liu Bei was a thief, because Cao Cao unified the whole northern China under the banner of Emperor Xian of Han Dynasty, with the Han regime established by Liu Bei in the southwest and the Wu regime established by Sun Quan in the southeast. Theoretically, the Cao Wei regime inherited most of the land area, population and influence of the Eastern Han regime, and Cao Pi's throne was granted by the last emperor of Han Dynasty, Emperor Xiandi, which is theoretically said. Moreover, at that time and later dynasties, Cao Wei was orthodox, which can also be seen from the records in historical books. For example, the biography of the supreme leader of Cao Wei was recorded as "Ji" in the History of the Three Kingdoms. For example, Cao Cao's biography was called "Ji of Emperor Wu", Liu Bei's biography was called "Biography of the First Master" and Sun Quan's biography was called "Biography of the Master Wu". Anyone who has read history books knows that Ji was an emperor.
Sun Quan asked who was Han and who was a thief, and the answers were different. Standing on Liu Bei's ambition, of course I think Cao Cao is a thief, while standing on Cao Cao's ambition, I think Liu Bei is a thief. From Sun Quan's standpoint, it doesn't matter who is the Han thief. As long as the Wu regime continues, then this question can't be answered at all. However, if we look at this question from the perspective of the last emperor of the Han Dynasty, then the answer is: they are all thieves, including Liu Bei, Cao Cao and Sun Quan.
Liu Xie, Emperor Liu Hanxian of the Han Dynasty, was the emperor who had been a puppet for the longest time in the history of China. Emperor Xian of Han Dynasty was a puppet from birth. His fate has always been in the hands of others, never in his own hands. At the age of 9, he was made emperor by the traitor Dong Zhuo and was controlled by Dong Zhuo. If 9-year-old Liu Xie had been sensible, he would have thought Dong Zhuo was a thief. Later, Liu Xie was controlled by Wang Yun, Li Jue and Guo Si, and finally by Cao Cao. In Liu Xie's mind, Cao Cao was a Han thief, so he rebelled against Liu Xie. However, Liu Xie was unable to get rid of Cao Cao, so he could only survive. But deep down, Liu Xie always wanted to kill Cao Cao, so from Liu Xie's point of view, Cao Cao was the biggest thief. What about Liu Bei and Sun Quan? Although Liu Bei is doing his own business under the banner of revitalizing the Han Dynasty, he never cares about the life and death of Emperor Xian. Even in the event of imperial edict matching clothes, Liu Bei didn't want to participate in it at first. Later, Cao Cao and Liu Bei boiled wine to talk about heroes, which made Liu Bei feel that Cao Cao had doubts about him. Liu Bei only wore clothes to participate in the imperial edict. In the end, Liu Bei proclaimed himself emperor. Liu Bei never thought about saving Emperor Xian of Han Dynasty for a day, so Emperor Xian of Han Dynasty also thought that Liu Bei was a thief, under the banner of rejuvenating the country.
Cao Cao, Liu Bei and Sun Quan As for Sun Quan, in the eyes of Emperor Xian of Han Dynasty, they are no different from the local warlords who are independent, and they don't care about the life or death of Emperor Xian of Han Dynasty. Who will try to save the world for the Han Dynasty? No one, so Emperor Xiandi of Han also thought Sun Quan was a thief. If we look at this question from an objective historical perspective, then the answer is: Liu Bei, Cao Cao and Sun Quan are not thieves. When the regime of the Eastern Han Dynasty developed to the period of Emperor Xian of the Han Dynasty, the foundation of its existence had been destroyed and could not be saved. Just like a terminally ill person, it is only a matter of time before he dies. The demise of the Eastern Han Dynasty is an objective factor of historical development, not because of anyone. The law of its demise is that a dynasty has come to an end.
Since the end of the Eastern Han Dynasty, the three major forces, Liu Bei, Cao Cao and Sun Quan, which rose in troubled times, all rose by virtue of their own abilities and strength. Their rise is not accidental but inevitable. Cao Cao could not defeat the combined forces of Sun Quan and Liu Bei in Battle of Red Cliffs. Although there are various reasons, history is history, which has happened and cannot be changed. Can only follow the trend of the times. Liu Bei, Cao Cao and Sun Quan, as the tripartite forces of the Three Kingdoms, are not thieves, but heroes, all of whom have left their influence in the dust of history.
