As temperatures rise, the ice on Xinjiang's Tianchi Lake begins to melt, marking the arrival of the limited blue ice season. The lake's crystal-clear ice scatters blue light under the spring sun, creating a dreamy landscape of shimmering ice and rippling water. This rare spectacle, lasting less than a month from March to April, is part of the UNESCO World Heritage site's efforts to boost winter and spring tourism, inviting visitors to experience the unique beauty of the Tianshan Mountains.
