Liu Bang, the founding emperor of the Han Dynasty, naturally had nothing to say about his strength. But before he became famous, he also experienced many life-threatening moments, at the Hongmen Banquet, he was always facing the danger of being in a different place, in front of him was the heroic and fierce Xiang Yu, "Man is a knife trick, I am a fish meat" can describe his situation.

At this critical moment, Fan Duo suddenly rushed in, an impassioned speech, so that Xiang Yu spared Liu Bang, and later Fan Duo also saved Liu Bang's life many times, it is reasonable to say that Liu Bang should be grateful to Him, this is also a lifelong friendship, but in his later years Liu Bang sent someone to kill Fan Duo, which was mainly driven by political interests.
In 206 BC, Liu Bang took the lead in leading troops into Xianyang, bypassing the main offensive of the Qin army, and Xiang Yu directly defeated the main force of the Qin army, and ran all the way to find Liu Bang, the two had agreed that whoever entered Xianyang first would be called king, but Liu Bang was using a sinister move, so Xiang Yu was naturally unconvinced, the Hongmen banquet was to ask for an explanation, originally Liu Bang would almost die, if it were not for Fan Duo, I am afraid there would be no later Han Dynasty.
In the early days of the founding of the Han Dynasty, Liu Bang was still very good to him, and he was knighted and added to the official, but because Fan Duo was married to Lü Lu's sister, fan Duo was Liu Bang's brother and brother-in-law, but in fact Fan Duo was a person from Lü Hou's side, and Liu Bang's favorite son was Liu Ruyi, and he was afraid that after his death, Lü Hou would attack Liu Ruyi, so he sent Chen Ping and Zhou Bo to kill Fan Duo.
At this time, Liu Bang was still lying on the sickbed, and Fan Duo was still being rehabilitated outside, there was a long distance from the capital, it would take a long time to get there, Chen Ping and Zhou Bo did not intend to kill Fan Duo, but to arrest him back to Liu Bang for disposal, because after all, Fan Duo was a person of Lü Hou, and there was a high probability that Liu Ying would take the throne in the future, then Lü Hou must be powerful, and Liu Bang also had little time, if he killed Fan Duo, he would not have a good end.
Their speculation is indeed correct, on the way to go, Liu Bang died, the moist emperor was Liu Ying, so the person in power became Lü Hou, so Liu Bang did not kill Fan Duo, and the last Fan Duo died of illness, but his family did not have such a good ending, after all, political disputes are not so easy to get rid of.
After Lü Yan took power, she vigorously suppressed the people surnamed Liu, did not want these forces to develop, and then vigorously developed the Forces of the Lü Family, which caused dissatisfaction among the people surnamed Liu in the world, so the descendants of the Liu family everywhere began to rebel against the Lü family, including Chen Ping and Zhou Bo, who were in the palace, and it was naturally more convenient to move.
However, it is certainly not so easy to kill Lü Yan, it is necessary to start from the surrounding forces first, the Lü family is about to usher in a catastrophe, as the fan duo family of the same camp will naturally not have a good end, they have not escaped the disaster after all, Fan Duo's wife and son have been brutally killed, and the only surviving heir is the son of the concubine, Fan Shiren.
Later, after many years, the Han Wen Emperor Liu Heng took the throne, Fan Huan saved the life of the founding emperor Liu Bang many times before his death, it should be a respected person, although Liu Bang once wanted to kill him, but the people of later generations must have done enough in superficial kung fu, so the people of Fan City who survived by chance ushered in good luck.
Originally he was born of a concubine and would not inherit the title of Fan Duo, but now he has all this, of course, this is also a helpless move, as the only surviving son of Fan Duo, this practice can also be regarded as giving Fan Duo an explanation, so that his descendants continue to enjoy the glory and wealth he deserves, and give him an official position.
In fact, Fan Duo was originally a founding hero, he saved Liu Bang many times, and the founding emperor had a lifelong friendship, if it were not for the political intrigue, he would not have almost become a victim of the monarch's suspicion, but fortunately he was not killed in the end, but his family was not so lucky.
