Children learn to write Spring Festival couplets at a charity school in Hangshan Village, Taihe Township, Nanfeng County, east China's Jiangxi Province, Feb. 5, 2018. Hangshan Village is located in a remote area in the region. As many parents here leave home for work, many children had to stay at home. Xi Weixing, a local villager who started business in Guangdong Province, builds a charity school here, providing free-of-charge after-school courses plus lunch for the left-behind children, whose parents usually work as migratory workers in other cities. The school is open to children on weekends and holidays. (Xinhua/Song Zhenping)
