Time for square-dancing to face the music

The phenomenon of Chinese square-dancing, which is known for generating widespread public complaints about loud music, will be regulated and choreographed by China's sports and culture authorities.

Developed as a positive form of exercise, Chinese square-dancing - generally groups of older women who dance in open spaces to loud music - has sparked heated debates online.

Complaints over the noisy music and even pictures of Chinese grannies occupying sites such as New York's Sunset Park and the square in front of the Louvre in Paris, have made headlines overseas.
