Primary students enjoy themselves in exercises when taking part in a nationwide sports hour campaign in Jinan, north China's Shandong Province, on Sunday morning, April 29, 2007. The campaign was launched in a situation where more and more Chinese students are suffering from obesity, with average physical strength having declined in recent years, related sources said. The compulsory drills pulled hundreds of millions of students from primary, middle schools and universities out of classrooms and on to playgrounds.
