Qulu Lake is located in the volcanic zone and is affected by nearby volcanic activities. There is a hot spring at the bottom of the lake. There are also many volcanoes and natural geothermal hot springs near the lake . The main hot springs near Kussha Lake include Renfu Hot Spring, Heqin Hot Spring, Sanxiang Hot Spring and Shatang Hot Spring. On the west bank of Lake Qufu Road, geothermal hot springs will emerge from the ground. Known as the sand soup, this landscape is a famous landscape on the shore of Lake Kussharo. Because of the cold winter, there are hot springs on the shore of the lake. The warm lake has become the winter home of wild swans. Therefore, every winter, there are dozens or even hundreds of swans, so I gave it up. The name of "Swan Lake". Sand soup is a nature reserve, but it does not surround the animals like ours. We can get close to these lovely swans. As soon as the car stopped, we heard the sound of the swan coming from the lake. Five or sixty swan swam in the lake, or screamed at the neck, or slap the wings to chase each other, and it was very lively. The swan's wings are graceful, but when they fall on the ice, they are not so elegant. Because they are too slippery, they must walk carefully and sway and slowly walk down into the lake. I don't know what the swan is like. I made up for the picture. Unfortunately, their big feet are awkward, but they are still relatively stable and have not given me this opportunity.
