The Chinese Dragon, also known as the loong, long or lung, is a legendary creature in Chinese mythology, Chinese folklore, and Chinese culture at large. Chinese dragons have many animal-like forms such as turtles and fish, but are most commonly depicted as snake-like with four legs. Academicians have identified four reliable theories on the origin of the Chinese dragon: snakes, Chinese alligators, thunder worship and nature worship. They traditionally symbolize potent and auspicious powers, particularly control over water.

Chiwen is an roof ornamental motif in traditional Chinese architecture and art. Chiwen is also the name of a Chinese dragon that mixes features of a fish, and in Chinese mythology is one of the nine sons of the dragon, which are also used as imperial roof decorations. As architectural ornaments or waterspouts, they are comparable with Western gargoyles, but are not related to the mythological character.
