As a swing, Wei Bao should please both sides, but why did he swear at Liu Bang?

After Wei Bao betrayed Liu Bang, because of Wei Bao's superstition, he dared to swear at the emissary sent by Liu Bang to surrender. When preparing to leave Liu Bang, he first found a fortune teller to predict his future. As a result, the fortune teller said that although Wei Bao himself was not an emperor, he could have a son as an emperor. Wei Bao, who was overjoyed, believed the fortune teller's words, so he became very inflated, disdaining Liu Bang's surrender and even humiliating him.

Chu and Han contended, the situation was changeable, and the strength of Liu Bang and Xiang Yu also changed at any time. Wei Bao, who originally followed Liu Bang, was born a swing, always acting according to immediate interests. When Liu Bang was defeated by Guan Yu in Pengcheng, it was the time when Liu Bang needed the support of people around him most. But Wei Bao was unfaithful at this time, thinking that Liu Bang might be difficult to confront Xiang Yu again, and secretly planned to betray Liu Bang and take refuge in Xiang Yu.

So Wei Bao asked Liu Bang for leave on the grounds of going home to visit his seriously ill parents. At this point, because there is no good man around, he dare not offend his supporters easily, thinking that Wei Bao still followed him until now, so Liu Bang believed Wei Bao's story and agreed to Wei Bao's departure. After Wei Bao, who had a successful strategy, returned to Wei, in order to give Xiang Yu a surrender gift, he began a series of acts of betraying Liu Bang, which made Liu Bei fall into a more unfavorable position.

After learning the truth, Liu Bang was very depressed. But at this time, Liu Bang couldn't concentrate on dealing with Wei Bao, so he had to send messengers to Wei, hoping that Wei Bao would come to their senses, for mutual affection. Who knows, superstitious Wei Bao is convinced that his future son is the emperor, and he gets carried away. He refused to accept surrender, was hostile to the emissary, angered Liu Bang, and was finally attacked and killed by Liu Bang.

It is worth mentioning that the fortune teller said that Wei Bao's son was the emperor, which made people laugh and cry, because after Wei Bao was eradicated by Liu Bang, Wei Bao's concubine became the concubine of Liu Bang's harem. A few years later, she gave birth to a son who did inherit the throne, but not Wei Bao's son.
