The Chinese dragon (simplified Chinese: 龙; traditional Chinese: 龍; pinyin: lóng) is the highest-ranking animal in the Chinese animal hierarchy, strongly associated at one time with the emperor and hence power and majesty (the mythical bird fenghuang was the symbol of the Chinese empress), still recognized and revered. Its origins are vague, but its "ancestors can be found on Neolithic pottery as well as Bronze Age ritual vessels."[23] Tradition has it composed of nine different animals, with nine sons, each with its own imagery and affiliations. It is the only mythological animal of the 12 animals that represent the Chinese calendar. 2012 was the Chinese year of the Water Dragon.
