Chen Qiuju talks with her 11-year-old student Zhang Jian. The boy's father is a migrant worker, leaving him and his mother alone at home. Zhang used to be the naughtiest boy in class, quarreling and fighting with other boys. However, he has made great progress and is well-behaved now under Chen's guidance. "He sends me flowers and lovely sweet potatoes during the festival which deeply moves me." [Photo by Chen Weisong/China.org.cn]
