Aerial view of Yuncheng Salt Lake in N China's Shanxi

Aerial photo taken on Feb. 28, 2019 shows a view of the Yuncheng Salt Lake in Yuncheng, north China's Shanxi Province. Yuncheng Salt Lake, as one of three inland salt lakes with sodium sulfate in the world, covers an area of 132 square kilometers. In the biting winter, clear "flowers" shaped like coral form as mirabilite crystallizes on the lake surface. As the temperature rises, the lake looks like a giant colorful "palette" from the air.
