Many names in "Knife in the Snow" give people a sense of sight. For example, Chulushan, with a big figure, always reminds people of some historical figures. In fact, the author of "Fierce Knife in the Snow" is familiar with history and has integrated many historical figures to shape the characters in "Fierce Knife in the Snow", but the protagonist Xu Fengnian has no historical prototype.

Xu Fengnian, the prince of the Northern Liang Dynasty, is famous for his image of ten thousand people, but he has a plan in his heart. Equipped with double knives, Dahuang Hospital was awarded by Wang Zhonglou.

Xu Fengnian studied under Shiguo Li Yishan, and was half a teacher and half a friend with Li Chungang, one of the four great masters in Jianghu before Jiazi. After the Battle of Two Mangs, Xu Fengnian unloaded the burden of North Wang Liang, changed the North City to Luoyang City, and became addicted to Jianghu from then on.

Xu Fengnian achieved his goal of practicing martial arts, revenged his mother and fulfilled his father's last wish. Although 300,000 soldiers in Beiliang died, they died for the people of the Central Plains, and they died a fair death. As for Xu Fengnian, retiring from the Jianghu and refusing to be emperor should also be the best choice for Xu Fengnian.
