Gou Mang

One of several cosmic dragons from Chinese mythology, Gou Mang, together with Rou Mang, is messengers of the sky gods and is sometimes represented as a double dragon. Gou Mang brings good fortune with the return of spring and is said to promote longevity, while Rou Shou represents bad fortune and the coming of autumn.
