History is the memory of things that have been said and done. —Carl Baker
After Liu Bang became emperor, the one thing he wanted to do most was to kill Han Xin first, and the reason why he had such a thought could only be blamed on Han Xin for pitting Liu Bang too many times, so that Liu Bang could not tolerate such a hidden danger around him. In fact, after Liu Bang became emperor, Han Xin did not have much ability to rebel anymore, but for Liu Bang, Han Xin had to die, and his reason was not only to solve hidden dangers, but also to kill chickens and scare monkeys.
Before Liu Bang became emperor, in order to seize the world, many kings with different surnames were sealed, and some of these people later received the surname "Liu" given by Liu Bang and became Liu Bang's confidants, while some of them always held power in the Han Dynasty under their own names. For Liu Bang, those who were not members of the Liu family were difficult to trust, so they wanted to use Han Xin's head to wake up those kings.
However, Liu Bang's approach only backfired, not only did not deter those kings outside, but after people saw Liu Bang's rogue disposition, more people wanted to oppose him, which also led to a very sad result, that is, the world that had just been pacified began to chaos again.
At this time, Liu Bang was very sorry, he really regretted killing Han Xin, but the reason for his regret was not whether he should kill Han Xin, but regretted that he killed han Xin too early, and he should first stabilize the kings and then kill Han Xin, that was the best choice. Someone should have been able to tell Liu Bang about this matter, but Liu Bang said that the empress dowager could not trust anyone, resulting in a bunch of confidants and strategists walking away, and Zhang Liang also chose to leave, and did not give Liu Bang a good advice.
As a result, because he killed Han Xin too early, Liu Bang did not have to go around suppressing rebellion outside until he was more than 60 years old, and when he was old, he had the opportunity to return to his hometown, saying "Make a big wind song, and and the andersons will guard the four directions!?" Sing the sadness of being an emperor.
