Introduction to Yanqi Lake: The Yanqi Lake, formed by excavation for dam construction, is surrounded by willows and peach blossoms are lying on the waves. It is clear and beautiful. Every autumn and winter, more than a hundred swan geese inhabit it. The red-lined peaks and mountains are towering. The huge rocks look like turtles looking at the sun, facing each other like camel humps, mist drifting in the air, winding around the top of the mountain. You can see Lucheng in the south and Shimen in the north, and you can have a panoramic view of thousands of things.
