On Friday, the Caka Salt Lake, located in Ulan County, northwest China's Qinghai Province, unveiled its breathtaking scenery in the twilight of dusk.

Caka Salt Lake is dubbed China's "mirror of the sky", as the water is very clear, meaning it is also very reflective. It is located in the eastern Qaidam Basin, which has the largest salt reserve in the world.
