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.
