Tianchi is like sapphire and blue sky and white clouds, beautiful, the surface area is9.82 square kilometers, the circumference is13.1 kilometers, and the thawing is from mid-June to early December every year. The water is full of unique rainbow trout. The top of the mountain is windy, although the temperature is not low, it will feel a little cold, but as long as it is sunny, short sleeves can not be frozen, if the cloud can not see the Tianchi, can wait for the clouds to open the fog, because the weather becomes fast when the wind is strong.
