Located in Haixi Mongolian and Tibetan Autonomous Prefecture, northwest China's Qinghai Province, Mangya city has emerged as a popular tourist destination thanks to its striking natural landscapes. Among its most iconic attractions is Feicui Lake, or Emerald Lake, which spans roughly 26 square kilometers. The lake is rich in lithium, potash, mirabilite, and other mineral salts. Variations in mineral concentration give the water breathtaking shades of light blue, emerald green, and deep green, creating a scene that looks like an oil painting set against the vast canvas of the Gobi Desert.
