Gu Long
Neijia are a common theme in Chinese wuxia novels and films, and are usually represented as originating in Wudang or similar mythologies. Often, genuine internal practices are highly exaggerated to the point of making them seem miraculous, as in the novels of Jin Yong and Gu Long. Internal concepts have also been a source of comedy, such as in the films "Shaolin Soccer" and "Kung Fu Hustle".
