Photo taken on Jan. 19, 2016 shows the scenery of mirabilite rime on the Salt Lake in Yuncheng, north China's Shanxi Province. Mirabilite rime is formed when mirabilite crystalizes at a low temperature. The Salt Lake of Yuncheng, a typical inland saltwater lake, is the world's third largest sodium sulphate inland lake. Due to its high saltness, it is also called the "Dead Sea" of China. (Xinhua/Zhan Yan)
