The reason why Yan Bingyun backstabbed Fan Xian
There were several possibilities for why Yan Bingyun had backstabbed Fan Xian. It could be inferred that Yan Bingyun might have stabbed Fan Xian to protect the safety of the Qing Kingdom and prevent it from falling into internal strife. Fan Xian had discovered the collusion between the Second Prince and Eldest Princess in Northern Qi, as well as their illegal actions. Yan Bingyun might think that Fan Xian's actions would be detrimental to the Qing Kingdom. In addition, Yan Bingyun might have considered the stability and interests of the Qing Kingdom. He believed that Fan Xian's existence would cause turmoil in the Qing Kingdom, so he chose to betray Fan Xian to ensure the stability of the Qing Kingdom. However, there was no clear answer to the specific reason, because these explanations were based on the plot and character relationships in the novel "Celebrating Years".
