 The Dragon was associated with rain, and during the Han dynasty, a dance may be performed during a ritual to appeal for rain at time of drought.According to the Han dynasty text "Luxuriant Dew of the Spring and Autumn Annals" by Dong Zhongshu, as part of the ritual, clay figures of the dragons were made and children or adults may then perform a dance.The number of dragons, their length and colour, as well as the performers may vary according to the time of year.
