Water tanks have been built here to help ease water shortage and provide safe drinking water. Due to harsh environmental conditions such as the stony desertification and mountainous landform, Dahua County in Guangxi has long been a less developed area. In recent years, local government carried out many measures for the poverty alleviation work. The government helped local people build roads, repair houses and improve education.
