Summer is the main holiday season at Qinghai Lake because of the cool weather and beautiful views. But the tourism boom has also brought some ecological problems. We find some empty aluminum cans and plastic packets scattered by the lake.

The water is slightly cold and clear, which is so gratifying. Through the water I saw a small scaleless carp, one of the special inhabitants of Qinghai Lake.

I say goodbye to mysterious and beautiful Qinghai Lake after about an hour.
