Jianghu is a city in Guangdong Province, in southern China. It lies in the Pearl River Delta region, an area of dense urban development and manufacturing in the country's south.
The name Jianghu is also a well-known Chinese term referring to the social environment in which many Chinese wuxia, xianxia, and gong'an stories are set. The term is used flexibly, and can describe a fictionalized version of imperial China; a setting of feuding martial arts clans and the people of that community; a secret and possibly criminal underworld; a general sense of the "mythic world" where fantastical stories happen; or some combination thereof. A closely related term, wulin, refers exclusively to the community of martial artists that inhabit a jianghu setting. The terms jianghu and wulin have been borrowed into Korean as gangho and murim to refer to fiction set in Chinese-inspired martial arts worlds.
Beyond its location in Guangdong, the city is not widely documented in the available source material.
