The dragon (long 龍) is an auspicious animal in Chinese mythology. It is, although in appearance similar to the occidental dragon, a good animal and not a symbol of evils. The dragon is a scaly animal that can have different colours or sizes. In Spring it ascends to Heaven and hides itself in deep wells in Autumn.
Sages, mythological rulers or immortals are often said to ride on a dragon in their travels through the sky. It was also possible to breed dragons, like Master Dong 董, a servant of Emperor Shun 舜 who fed a lot of dragons. He was therefore given the family name Huanlong 豢龍.
Rubbing of a relief stone from the Han period, showing a rabitt and a toad in the moon (see the story of Chang E 嫦娥), and a green dragon (canglong 蒼龍) flying through the night sky.
