First, from the moment the life story is exposed, it is doomed to tragedy. In the background at that time, Qidan and Dasong were incompatible. Even Qiao Feng himself thinks that the Khitans are? Qidan dog? This also doomed his tragedy. He is a Khitan, grew up in Dasong, and became a beggar leader by his own efforts. However, even if his identity is revealed, it is unacceptable that Qiao Feng is a Khitan. Qiao Feng disdains explanation and flattery. He is too honest to be used by some unscrupulous people and exposed by Mrs. Ma. If Qiao Feng had been tactful enough, he wouldn't have been framed by Mrs Ma in public, but he was a perfect hero, Qiao Feng.
Second, I personally ruined my ordinary life. Qiao Feng was too persistent to find his father's killer. Even if the Wulin doesn't allow him now, he still wants revenge. On the way to revenge, he met Arju. If Qiao Feng can put down his hatred and choose to live outside the Great Wall with Arjun, it will be a perfect ending, but Qiao Feng is bent on revenge. This is his trouble. Arjun loves Qiao Feng and doesn't want to embarrass Qiao Feng, but he can't watch Qiao Feng kill his father and then be hunted.
Third, loyalty is hard to do. The war between Dasong and Daliao was the last thing Qiao Feng wanted to see, but he couldn't stop it. Qiao Feng's excellence lies in that he conquered everyone around him with his own verve. If another person advised Yeluji not to go to war, Yeluji would not take a reason and be a hero. In the end, Qiao Feng traded his life for peace between the two countries, and the outcome of a generation of heroes was not as good as that of an ordinary person. Qiao Feng's regret for Aru's death is irreparable.
