The inclusion of martial arts as a feature of jianghu was a recent development in the early 20th century. Novelists started creating a fantasy world of jianghu in which characters are martial artists and in which the characters' enforcement of righteousness is symbolised by conflicts between different martial artists or martial arts sects and the ultimate triumph of good over evil. Martial arts became a tool used by characters in a jianghu story to enforce their moral beliefs. On the other hand, there are characters who become corrupted by power derived from their formidable prowess in martial arts and end up abandoning their morality in their pursuit of power. Around this time, the term "jianghu" became closely related to a similar term, "wulin" (), which referred exclusively to a community of martial artists. This fantasy world of jianghu remains as the mainstream definition of "jianghu" in modern Chinese popular culture, particularly wuxia culture.
