A villager repairs a water tank in Dahua Yao Autonomous County, south China's Guangxi Zhuang Autonomous Region, Dec. 8, 2016. In the region, nearly half of poverty-stricken people live in areas with stony desertification which caused severe drinking water shortage. During China's 13th Five-Year Plan (2016-2020) period, local authorities have stepped up the constructions of water conservancy facilities, helping ease water shortage and providing safe drinking water for the locals.
