Yinzhan Hot Spring Reservoir is clear and wide. When the wind has subsided and the waves have calmed down, the reservoir looks like a big mirror, reflecting the surrounding landscape and the clouds in the sky. Visitors to this spot can enjoy fishing, boating, and swimming. The hot spring is crystal clear--colorless, odorless, and sediment-free. It has been rated first class in surface water environmental quality by the National Environmental Protection Bureau. And it contains minerals that are good for the body.
