In the Spring and Autumn Period, chivalrous men were a special group. He has the responsibility to alleviate difficulties and worries, protect his master's health, assassinate political opponents, retaliate, face others bravely, oppose injustice, value righteousness over profit, and keep his promise. Such people are called chivalrous men. During the Spring and Autumn Period, soldiers and civilians were divided into two categories: intellectuals sought jobs through knowledge and strategy, and warriors made a living through martial arts skills.

Most of the earliest samurai were aristocratic children. They study martial arts in order to become famous in the army. Samurai groups are gradually being replaced by civilians. These civilians who make a living from martial arts have become expensive customers in different countries. Like He of Chu, there are thousands of warriors, many of whom are warriors loyal to their martial arts masters.

Although some soldiers are not regular doormen, they are loyal, honest and trustworthy, and are not afraid of death. In some novels, such as "Three Heroes and Five Righteousness", chivalrous men such as Nan, Bei, Shuang and Xiao He all come from all walks of life. However, there is still a big gap between the real knight-errant and the knight-errant in our mind now.

In history, "chivalrous man" is the embodiment of justice and the spiritual sustenance of the people. In different historical periods and stages, "chivalrous man" also influenced the whole politics and society. However, with the development of social economy, "chivalrous men" are no longer a special group, but "chivalrous men" who live in all walks of life for self-defense. There are also knights in bodyguards, nursing homes, teaching places and entertainment places, as well as scholars, farmers, businessmen, officials, strongmen and lawless elements.
