Aerial photo taken on Nov. 13, 2018 shows water of a landslide-caused barrier lake on the Jinsha River flows through a drainage channel in the border area between Sichuan Province and Tibet Autonomous Region in southwest China. A drainage channel constructed by disaster relief staff successfully resumed the flow of Jinsha River, which had been blocked by a barrier lake formed following a landslide that hit the area on Nov. 3.
