Dragon dance () is a form of traditional dance and performance in Chinese culture. Like the lion dance, it is most often seen during festive celebrations. The dance is performed by a team of experienced dancers who manipulate a long flexible giant puppet of a dragon using poles positioned at regular intervals along the length of the dragon. The dance team simulates the imagined movements of this river spirit in a sinuous, undulating manner. The dragon dance is often performed during Chinese New Year. Chinese dragon(s) is a symbol of China's culture, and they are believed to bring good luck to people, therefore the longer the dragon is in the dance, the more luck it will bring to the community. The dragons are believed to possess qualities that include great power, dignity, fertility, wisdom and auspiciousness. The appearance of a dragon is both fearsome and bold but it has a benevolent disposition, and it was an emblem to represent imperial authority. The movements in a performance traditionally symbolize the power and dignity of the dragon. During the Han dynasty, different forms of the dragon dance were described in ancient texts. Rain dance performed at times of drought may involve the use of figures of dragon as Chinese dragon was associated with rain in ancient China, for example the dragon Yinglong was considered a rain deity, and the Shenlong had the power to determine how much wind and rain to bring. According to the Han dynasty text Luxuriant Dew of the Spring and Autumn Annals by Dong Zhongshu, as part of a ritual to appeal for rain, clay figures of the dragons were made and children or adults may then perform a dance. The number of dragons, their length and color, as well as the performers may vary according to the time of year. Other dances involving dragons may be found in a popular form of entertainment during the Han dynasty, the baixi (百戲) variety shows, where performers called "mime people" (象人) dressed up as various creatures such as beasts, fish and dragons.
