As temperatures rise in Korla, NW China's Xinjiang Uygur Autonomous Region, melting ice on the Dujuan River has expanded the habitat for over 400 wintering wild swans, drawing visitors to witness the graceful birds swimming against a backdrop of blue water and sky. Staff members from the local landscaping center regularly feed and patrol the area to ensure their safety, continuing a 20-year tradition of the swans wintering in the city.
