The unfrozen river is a section of the Haraha River. Because there is a lot of geothermal heat in the underground of the river, the hot springs are used all the year round, causing the water temperature to exceed zero degrees, so the river surface cannot freeze. Every day at sunrise and sunset, the sun shines through the birch forest on the hillside, which is the most beautiful moment. Under the light, the sunset of the west falls on the river, it is still very beautiful. The frozen river is like a nine-striped gold belt floating on the earth, with some cattle and white birch trees dotted around it, the whole picture is more dynamic. .
