A worker does his job to join together two girders of the Mafanggou bridge which is part of the Yinchuan-Xi'an high-speed railway in Wuzhong, northwest China's Ningxia Hui Autonomous Region, Aug. 25, 2018. As a major constituent of China's high-speed railway network, the 618-kilometer Yinchuan-Xi'an high-speed railway is scheduled to start operation by the end of 2020 with a designed speed of 250 kilometers per hour, and will greatly reduce travel time within Shaanxi, Gansu and Ningxia.
