In Chinese, Ya means duck, and Lu means green. The river derived its name from its color and its shape resembling to the head of a duck. Descending from the southern foot of Mt. Changbai in Jilin Province, it runs through Changbai, Ji'an, Kuandian, and Dandong, with a length of 795 kms, and finally empties itself into the Yellow Sea. It is the boundary river between China and Korea. The river passes through 300 kms of Dandong City, with vast water and beautiful scenery along the banks. There are two iron bridges over the river, one was erected in 1909 but was destroyed during the Korean War, the other was erected in 1940.
