In China, square dancing 广场舞 is a common form of community exercise and socializing in the evenings. It has simple dance routines that everyone can participate such as working people, seniors, and even youth. In Shanghai I saw mostly women and men dancing. People seem to participate to get exercise and have some fun while moving in sync to the beat of music on street corners. When I was photographing people were dancing to traditional music but I understand that modern music is also incorporated.
