The Yanhu Lake covers 132 square kilometers and is 30 kilometers in length. Scientists say it was formed about 50 million years ago. As one of the top three inland salt lakes in the world, the Yanhu Lake is rich in edible and industrial salts, such as sodium sulfate and magnesium sulfate.

Experts say the rising temperatures have resulted in unusually fast growth of the algae and brine shrimps in the lake. Different types of algae at different densities reflect different lights, producing a beautiful multi-color image, which gives viewers a spectacular aerial view.

People call the Yanhu Lake China's Dead Sea. Due to its high water density, swimmers can float naturally in the lake, making it a safe destination for many tourists.
