Chinese mythology
The Chinese dragon is one of the most important mythical creatures in Chinese mythology, considered to be the most powerful and divine creature and the controller of all waters who could create clouds with their breath. The dragon symbolized great power and was very supportive of heroes and gods. The conventional dragon has a certain description, however there are other dragons or dragon-like beings that vary from this description. For example, the Chi of mythology lacks horns. Dragons often chase or play with a mystical or flaming pearl. A dragon-fenghuang pairing is a common motif in art, the fenghuang often being called a "phoenix".
Chinese dragon
The number nine is special in China as it is seen as number of the heaven, and Chinese dragons are frequently connected with it. For example, a Chinese dragon is normally described in terms of nine attributes and usually has 117 (9x13) scales—81 (9x9) Yang and 36 (9x4) Yin.
This is also why there are nine forms of the dragon and there are 9 sons of the dragon (see Classical depictions above). The Nine-Dragon Wall is a spirit wall with images of nine different dragons, and is found in imperial Chinese palaces and gardens. Because nine was considered the number of the emperor, only the most senior officials were allowed to wear nine dragons on their robes—and then only with the robe completely covered with surcoats. Lower-ranking officials had eight or five dragons on their robes, again covered with surcoats; even the emperor himself wore his dragon robe with one of its nine dragons hidden from view.
