Dragon occupies a very important postion in Chinese mythology. It shows up in arts, literature, poetry, architecture, songs, and many aspects of the Chinese conscience. The origin of Chinese dragons is unknown, but centainly pre-dates the written history. Chinese dragons are legendary creatures in Chinese mythology and folklore, with mythic counterparts among Japanese, Korean, and Vietnamese dragons. In Chinese art, dragons are typically portrayed as long, scaled, serpentine creatures with four legs. In contrast to European dragons that are considered evil, Chinese dragons traditionally symbolize potent and auspicious powers, particularly control over water, rainfall, and floods. In yin and yang terminology, a dragon is yang (male) and complements a yin (female) fenghuang "Chinese phoenix".
The origin of Chinese dragon is not certain, but some scholars believe that it originated from totems of different tribes in China. Some have suggested that it comes from a stylized depiction of existing animals, such as snakes, fish, or crocodiles.

From its origins as totems or the stylized depiction of natural creatures, the Chinese dragon evolved to become a mythical animal. The Han Dynasty scholar Wang Fu recorded Chinese myths that long dragons had nine anatomical resemblances.

Further sources give variant lists of the nine animal resemblances. Sinologist Henri Doré lists these characteristics of an authentic dragon: "The horns of a deer. The head of a camel. A demon's eyes. The neck of a snake. A tortoise's viscera. A hawk's claws. The palms of a tiger. A cow's ears. And it hears through its horns, its ears being deprived of all power of hearing."

Chinese dragons are strongly associated with water in popular belief. They are believed to be the rulers of moving bodies of water, such as waterfalls, rivers, or seas. They can show themselves as water spouts (tornado or twister over water). In this capacity as the rulers of water and weather, the dragon is more anthropomorphic in form, often depicted as a humanoid, dressed in a king's costume, but with a dragon head wearing a king's headdress.

In modern times, belief in the dragon appears to be sporadic at best. There appear to be very few who would see the dragon as a literally real creature. The worship of the Dragon Kings as rulers of water and weather continues in many areas, and is deeply ingrained in Chinese cultural traditions such as Chinese New Year celebrations. Dragon kites are also used in these celebrations
