Swan Lake is the home of these beautiful swans. This is a beautiful place to integrate the landscape of flora and fauna, wetland landscape and water system landscape, and it is a pristine and quiet earth. The temperature around the four-week low is below minus 20 °, but the natural spring water here is dense, forming a natural wonder of winter water surface not icy, and various water grasses provide a rich food for the swans. The moment the white feathers of the swan wet the lake, the moment the ripples open, like a soaked note.
