Students having the same hair style take a break after a physical education class at the 5702 Factory School in Wugong, North China's Shaanxi province, Sept 2, 2010. The school, which enjoys a high reputation for its teaching quality, requires all female students to have the same haircut despite of the opposition of some girls. Boys are forbidden to add waves to their hair or have hair dyed. A deputy headmaster said the rigid measures are to keep students focused on their studies, local media reported. [Photo/CFP]
