The Chinese dragon, known as long or loong (/lʊŋ/ LUUNG) is a legendary creature in Chinese mythology, Chinese folklore, and Chinese culture generally. Chinese dragons have many animal-like forms, such as turtles and fish, but are most commonly depicted as snake-like with four legs. Academics 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 and weather.
