Parents anxious after cleaver attack in Changsha (3/3)

A parent at the gates of Guoqing Primary School in Changsha, capital of central China's Hunan province, signs a document on March 14, stating that parents who take their child home would accept responsibility for his or her welfare. The school management took this measure after several knife-wielding assailants attacked passers-by on a street near the school on Friday morning.[Photo by Lv Chunrong]
