Many of these activities are accompanied by singing, dancing, and instrumental performances that are art forms in their own right. They are mostly held as part of the festivals like Spring Festival and other days of significance. The Bamboo Pole Dance of the Li ethnic group is an example. The participants squat or kneel in pairs opposite each other and hold the end of a bamboo poles in each hand. The couples bring the poles together and apart in time with the rhythm of musical accompaniment. Graceful dancers perform between the moving poles, ensuring that they maintain a rhythm that is in time with the poles so as to avoid being trapped between them. This is a very skillful and entertaining sight.
