Quxielu Lake is the largest lake in the park, and is famous for its swimming, boating, warm volcanic sand, and the local version of the "Loch Ness Monster". It is said that there will be a large group of swans and wild cranes here. We didn't see any of them when we went there. We thought they were pitted. It is estimated that swans and wild cranes will fly in autumn and winter, and then the weather will gradually become colder.
