In the season when diseases and plagues are prone to occur, dance can play a role in eliminating disasters and diseases. There is no certain standard requirement for this kind of dance body movements. It only needs people to sing and dance heartily, so it can exorcise evil spirits and eliminate disasters and keep fit. Primitive ancestors have realized this and invented dances that advocate human functions. The traditional dance method of treating diseases and keeping fit is still very popular. Dancing with lions and yangko in Han festivals, as well as Diane dance in Mongolia, are also the historical heritage of our ancestors' disease prevention and fitness.
