This photo taken on April 2, 2018 shows icicles on a wind-driven iceberg ashore Ulunggur Lake in Fuhai County, northwest China's Xinjiang Uygur Autonomous Region. In spring, the frozen surface of Ulunggur Lake began to thaw, leaving fractured ice under the sway of strong winds. Blown by the winds towards the lakeshore, the ice blocks then accumulate and form icebergs that stretch for over ten kilometers. (Xinhua/Hu Huhu)
