Thence it descends into the Korfen Valley and proceeds by Chelu to Korfen on the right bank of the Amur River. This line covers a distance of 350 miles, two thirds of which run on comparatively level land and one third in mountainous district. This is the shortest line from Tungchin to the Amur River and the Russian territory on yonder side. g. The Tungchin-Yaoho Line This is the seventh line that radiates from this railway center.
