The background of chivalrous image in ancient history books

The origin of "chivalry": the concept of "chivalry" was first seen in Five Mistakes by Han Feizi: "Confucianism confuses the law with literature, and chivalry forbids it with force." In this paper, "Ranger" and "Private Sword" are both called, while "Sword Holder" is characterized by "gathering disciples and holding festivals to show their names"-the concept of "knight" in later generations appears here, so it is no wonder that Sima Qian wrote the biography of Ranger, starting with "Han Feizi". It's just that this statement is vague and there are no specific examples; It was not until Historical Records Biography of Rangers that the basic characteristics of "chivalry" were outlined in detail.
