Girls sit in a circle to play Drop the Handkerchief at Zhuhe Road Elementary School in Handan, North China's Hebei Province, May 28, 2014. In this game, one player is running around the circle with a handkerchief and puts it behind any of the players, who, if found out, chase the former around the circle. If the latter fail to catch the former before the person sit down in his or her original place, the latter is the one to drop the handkerchief. If the former is caught, he or she should perform to the other players. [Photo/IC]
