In 2004, a project diverting water from the Yellow River eased Hanjiaoshui's water shortage. Many migrant workers returned hometown. Under the guidance of local government, they planted watermelon and developed cultivation industry. In March of 2017, Ningxia started the construction of another water project to improve water supplies in Hanjiaoshui. (Xinhua/Guo Xulei)
