Workers shovel mirabilite onto a conveyer belt at the salt fields of Yanhu Lake in Yuncheng city, Shanxi province, Jan 14. Yanhu Lake, an inland saltwater lake covering an area measuring 132 square kilometers, is called China's Dead Sea due to its high salinity. The nitrate and salt produced from the lake, including sodium sulfide and barium sulfate, are important raw materials and sell well in China and abroad. Winter is the best season in which to harvest salt. [Photo/Shanxi Daily]
