Kids learn aerobic dance moves for free under the direction of a fitness instructor at the Zhongdajiudeli community gym in Shanghai's Songjiang district on Aug 17, 2011. The gym opens its dance room and swimming pool free of charge for kids in the community this summer during the slow periods when there are few other users. The service allows children to enjoy a healthy and cool summer holiday instead of being addicted to TV or the Internet. [Photo/Xinhua]
