Chinese students kick a handmade shuttlecock in front of a washroom on a rooftop playground at a primary school for migrant workers' children in Wuhan on April 11, 2005. The school is built on the second floor of a farmers' market in the city, with the playground on the rooftop of the two-storey building. About 406 students study at the school. The Chinese characters read "It's glorious to maintain personal hygiene." Photo: Reuters
