"The Biography of Knights" is one of the famous chapters of "Historical Records", which records the historical facts of the famous knights Zhu Jia, Ju Meng and Guo Xie in the Han Dynasty. Sima Qian realistically analyzed different types of knights, fully affirmed the "heroes of the common people", "the knights of rural tunes", and "the knights of Luxiang", and praised them for "their words must be true, their deeds must be resolute, and their promises must be true." "If you don't love your body, you will go to the misfortune of a scholar... you won't care about your abilities, and you won't criticize your virtues" and other noble qualities. These people at the bottom of society, who were regarded by Ban Gu as "crimes that cannot be punished" ("Han Shu·Youxia Biography"), have become heroes who have conquered the world in Sima Qian's writings. He expressed sympathy for their misfortunes and expressed sympathy for their persecution. Their people expressed great indignation, revealing the hypocritical and unfair nature of the laws of the Han Dynasty, and showing the author's progressive view of history and the people's character of the book "Historical Records". Of course, the author denies and criticizes those heroes who are "thieves of plantar and live among the people" who are regarded as "the shame of the Zhu family". At the same time, the author used Confucianism to describe the heroes and wrote about Gongsun Hong and others' actions to punish the heroes, euphemistically expressing the author's anger towards such Confucians. Ban Gu, a feudal historian, called this article "retreating from being a scholar and advancing to become a hero" ("Hanshu Biography of Youxia"). This shows the progress of this article from another perspective.
