Beijing, July 9 (Youth.cn) - On July 6, 2025, in Haixi Mongolian and Tietan Autonomous Prefecture, Qinghai Province, the Emerald Lake presents a dramatic landscape as it complements the snow-capped mountains.

The Emerald Lake stands as a paradigm of coexistence between industrial heritage and natural endowment. Over 30 mining ponds within the scenic area display a gradient spectrum from Tiffany blue to emerald green, owing to varying concentrations of elements. Photo/CFP
