Yuncheng Salt Lake, located in Jinnan Basin, Shanxi Province, China, was formed in the fourth generation of Cenozoic era. Because the mountains go out to sea, a large number of salty minerals gather here, and after long-term precipitation and evaporation, a natural salt lake is formed. In feudal society, the salt tax of Yuncheng Salt Lake once accounted for one-eighth of the national fiscal revenue, which made great contributions to the survival and reproduction of the Chinese nation.

Yuncheng Salt Lake is comparable to the world-famous Dead Sea in Israel. The black mud in the lake contains seven kinds of constants and sixteen kinds of trace elements. People can row boats in the lake, and the black mud in the lake can beautify the skin, so Yuncheng Salt Lake is called the sea of death.

Yuncheng Salt Lake is the third largest inland lake of sodium sulfate type in the world, with an area of 65,438 0.32 square kilometers and a development history of more than 4,000 years. Salt Lake is bounded by Zhongtiaoshan in the south, Mingtiaogang in Emei in the north, Yaotai in Sushui in the east and the old capital of the Yellow River in the west. The lake is covered with silver, vast and boundless, surrounded by reed wetlands, and waterfowl gather.

The ancient Yanchi Temple is located on the bank of the salt lake. Yanchi Temple is spectacular in scale, rigorous in structure, bright and novel in layout and magnificent in architecture, with a total area of 26,000 square meters and a history of over 1000 years. Here, the Three Great Halls, Salt Culture Museum, Guang Hai Building, Gexun Building and Salt Mining Workshop in Han and Tang Dynasties are a series, which allows visitors to appreciate the profoundness and infinite charm of salt culture and Yellow River culture while enjoying the beautiful scenery of Yuncheng Salt Lake.
