Hua Jianghu: Bu Liang Ren IV

Wuxia (武俠), which literally means "martial heroes", is a genre of Chinese fiction concerning the adventures of martial artists in ancient China.

The heroes in wuxia fiction typically do not serve a lord, wield military power, or belong to the aristocratic class. They often originate from the lower social classes of ancient Chinese society. A code of chivalry usually requires wuxia heroes to right and redress wrongs, fight for righteousness, remove oppressors, and bring retribution for past misdeeds. Chinese xia traditions can be compared to martial codes from other cultures, such as the Japanese samurai bushido.

Note: It is difficult to categorize Wuxia and Xianxia without haven't experienced the show, so there's likely some overlap or ambiguity in this Stack.
