Before his death, Liu Bang sent Zhou Bo and Chen Ping to kill Fan Duo. Who did Liu Bang kill Fan For?
In fact, the reason why Liu Bang did this was the same as the way he operated to change the prince.

Does Liu Bang want to change the prince? Would very much like to. He was indeed dissatisfied with his crown prince Liu Ying, and the reason why he was dissatisfied with his crown prince Liu Ying was that he felt that this prince's personality was too weak. If this prince inherits the throne, it is very likely that his country and mountains will not be able to continue in the future, so he really wants to change the prince.
However, after passing some evaluation, Liu Bang believed that it was more appropriate to let Liu Ying inherit the throne than to let Liu Ruyi inherit the throne. The more appropriate reason is that Liu Ying is not better than Liu Ruyi, but because Liu Bang knows that he can no longer live after Liu Ruyi grows up slowly. If Liu Ruyi grew up slowly, Liu Bang died. Then, Liu Ruyi's coming to be emperor is definitely more appropriate than letting Liu Ying become emperor. However, Liu Bang's body could not resist it, and he could not wait for the day when Liu Ruyi grew up.
In this case, he can only choose Liu Ying. Why? On the one hand, Liu Ying was an adult and a changjun, on the other hand, Liu Ying had the support of Lü Hou and many ministers in the court, which made Liu Ying's ability more average, but with the support of these people, Liu Ying was more able to protect the Han Dynasty than Liu Ruyi.
Although Liu Bang had already decided not to change the crown prince, Liu Bang still had one problem that could not be solved, that is, the problem of Lady Qi. Lady Qi has been making trouble for Liu Bang to change the crown prince, and Liu Bang did not change in the end, which makes Liu Bang still have a problem that cannot be solved, that is, who will guarantee the safety of Lady Qi and Liu Ruyi?
After all, Lady Qi had followed Liu Bang for many years, and Liu Bang was very satisfied with Lady Qi and at the same time liked Liu Ruyi very much. For their safety, Liu Bang could not fail to consider.

It was precisely because of this that Liu Bang was afraid that Lü Hou's forces were too strong. In Liu Bang's view, in order to reduce Lü Hou's threat to Lady Qi, the most important thing was to attack the forces of Lü Hou's clique. As a person in charge of military power and with great prestige in the army, Fan Duo was an object of Liu Bang's attack. As long as Fan Huan was defeated, Lü Hou's strength would become weaker, and their threat to Lady Qi would be less.
In addition to reducing their threat to Lady Qi, there is also a role in cracking down on Fan Duo, that is, to reduce Fan Duo's threat to Liu Ying. Fan Duo is a foreign relative for Liu Ying, and when the king's personality is relatively weak, or the king's age is relatively young, it is the time when the foreign relative's monopoly is the most serious. That is to say, at that time, Liu Bang did not think of the possible dictatorship of Lü Hou at all, and he thought more about the monopoly of foreign relatives, after all, foreign relatives were men, and they were more likely to get involved in power in the dynasty, and it was easier to seize the throne of the weak king.
Zhou Bo and Liu Bang are not related, but Liu Bang used Zhou Bo to replace Fan Duo, obviously, in Liu Bang's view, although Zhou Bo was a foreigner, Zhou Bo was very loyal to the Liu family, and he could not have monopoly power.
Later, when Liu Bang was entrusted with orphans before his death, he also asked Lü Hou to hand over military power to Zhou Bo. It can be seen that Liu Bang has great trust in Zhou Bo.
Liu Bang wanted to kill Fan Duo, and why he wanted Zhou Bo to take his power was also based on such considerations.

However, when Liu Bang sent Zhou Bo to kill Fan Huo, he also did one thing at that time, that is, to let Chen Ping and Zhou Bo do it together. Liu Bang sent Chen Ping and Zhou Bo to kill Fan Duo together, I don't know if Liu Bang felt that Zhou Bo's intelligence was not enough, and he needed Chen Ping to help him with advice, or if he had other ideas, now we are not too clear.
Thinking that Zhou Bo was not thoughtful enough to consider things, it made sense to let Chen Ping help him with advice.
In the end, Chen Ping did not kill Fan Duo, but brought Fan Duo back, which I don't know whether Liu Bang had anticipated it beforehand or did not expect it. If Liu Bang did not expect this in advance, then it means that Liu Bang really asked Chen Ping to help Zhou Bo with advice.
However, if Liu Bang had anticipated that Chen Ping would release Fan Duo in advance, then it was very likely that Liu Bang did not really want to kill Fan Duo, but just wanted to teach Fan Duo a lesson. Because if Fan Duo was killed and completely handed over the military power to Zhou Bo, a foreigner, Liu Bang did not seem to be very at ease. After Liu Bang became emperor, he immediately killed the seven princes with different surnames, which was a manifestation of his lack of confidence in handing over military power to these people with foreign surnames.
In short, I think that Liu Bang also made the move of killing Fan Huan after careful consideration at that time. Whether or not he was able to kill Fan Duo in the end would have a great effect on ensuring the stability of the Han Dynasty and protecting Lady Qi's mother and son. This was a foolproof strategy that Liu Bang had in mind at that time.
