Second-grader Tang Lei (front) and her classmate Tang Yisi play rope-jumping during recess at Xiehe village of Yantan town in Dahua Yao ethnic autonomous county, Guangxi Zhuang autonomous region, May 17, 2010. With more villagers moving away to become migrant workers, more children are leaving with their parents. Facing a shortage of students, the primary school decided to only accept students under third grade, while older students attend a bigger school a few kilometers away. The school has only one teacher, Wei Fengmei, who teaches all subjects, including Chinese, English, math, music, art and physical education (PE). The two girls in the second grade have become very good friends. They will celebrate the upcoming Children's Day together. [Photo/Xinhua]
