Nuo, also called the nuo sacrifice or nuo ceremony, was originally a type of sacrificial and magic ritual held to expel evil spirits and pestilence. Its name is derived from one such ritual, where people shouted nuo, nuo to drive away the devil.
The nuo ritual procedure includes inviting, welcoming and thanking spirits. Following the solemn ritual, nuo drama is performed to entertain the spirits. Masked performers with whips dance to the sound of different mysterious tunes -- some wearing black, white or red masks with varied expressions -- from the amiable to the frightening and ferocious.
