Villagers build a water tank in Yao Autonomous County of Du'an, south China's Guangxi Zhuang Autonomous Region, July 23, 2019. 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.
