Children walk home together after school in Pingluo village, Guangxi Zhuang autonomous region, March 19, 2013. They are called "left-behind children", because their parents have moved to urban areas in search of long-term jobs as migrant workers. They are left behind in the countryside and cared for by relatives – usually grandparents. They are separated from their parents for many years. There are in all 1.4 million left-behind children in Guangxi; in China, the total is 58 million. [Photo by Meng Zengshi/Asianewsphoto]
