Built by the Japanese, the Yalu River Border Railway Bridge is located in Ji'an City, Jilin Province. The main scenic spot is a four-story bunker which is rarely found in China. During the war to resist U.S. aggression and aid Korea, the voluntary army entered into DPRK through this bridge. The bridge withstands the War of Resistance Against Japan, the Liberation War and the war to resist U.S. aggression and aid Korea. Its trail of damages left by the bombardment by the U.S. during Korea War evidences the history. On the bridge, one can enjoy the local customs and practices across the river, and the local features. Visitors can experience crossing the border between China and DPRK with only one step on the border river, border bridge and border dam.
