I feel that asking this question is a bit inexplicable and wonderful, first to understand the trajectory of Liu Bang, Liu Bang was indeed born in Chu in his early years, and he lived in Chu for most of his life, but as a commoner, how much affection did he have for this kind of feudal and aristocratic political state at the end of the Chu State?
Since the Chu State did not give people what they wanted, why did they let the family focus on the Chu State? You are a hooligan, not taking money, and wanting people to work for nothing!
After Xiang Yu destroyed Qin, he continued to establish Western Chu, because his Xiang family had been Chu generals for generations, and the true and true Chu nobles and roots were Miao Hong, but what about Liu Bang? What does he have ? The last King of Chu was very beloved? The king of Chu Huai was loved by people, deceived by the Qin people, and returned to Chu in a coffin, and the Chu people were pitiful, like sad relatives. But by the time Liu Bang raised his army, King Huai had been dead for almost a hundred years? Isn't his ancestor still had many feelings?
Moreover, Liu Bang's idol had nothing to do with the Chu people, because he admired Wei Guoxin Lingjun very much, and he personally went to Daliang City to find the whereabouts of Xin Lingjun!
But as a reckless hero himself, even his own son could throw him out of the car after the Battle of Pengcheng in order to escape, how much affection did he have for Xin Lingjun, a famous warrior of the Warring States? Not to mention the Chu state? He even had the luxury of asking him to establish a country with the name of Chu.
And the reason why he established Han was once sealed in Hanzhong, was for the King of Han! In this case, you will also carry Chu Jianhan.
In fact, there is another example that can reflect his original intention of betraying Chu Lihan from the side: that is, six hundred years later, his brother's descendant Liu Yu established Liu Song and did not restore the Han Dynasty, you must know that this is the real blood thicker than water, people have no idea, Liu Bang and chu state have no half-cent relationship, why restore the Chu state?
