Chinese culture
Chinese dragons are legendary creatures in Chinese mythology, Chinese folklore, and East Asian 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. They traditionally symbolize potent and auspicious powers, particularly control over water, rainfall, typhoons, and floods. The dragon is also a symbol of power, strength, and good luck for people who are worthy of it in East Asian culture. During the days of Imperial China, the Emperor of China usually used the dragon as a symbol of his imperial power and strength. They are also the symbol and representative for the Son of Heaven, the Mandate of Heaven, the Celestial Empire and the Chinese Tributary System during the history of China.
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.
