Beijing, August 1 (Youth.cn) - A photo taken on July 21st, 2023 in Haixi Mongolian and Tibetan Autonomous Prefecture of Qinghai Province shows the scenic West Taijinar Lake in Golmud City. The G315 National Road, a popular tourist route, cuts through the middle of the lake, separating the water into two sides—one blue and the other green. The green color is a result of the higher copper ion content in the lake water, while the blue color is due to the high salt content, reflecting the sky and creating a stunning contrast of colors during the summer, making the scenery even more enchanting.
