Longjing introduction: Longjing is located between Yanmen and Yanzhen. Under the hundred-foot cliff, there is a pure and sweet well, known as Longjing. The cliff is high and wide, green and yellow, and is reflected in the lake water, like a mural. It is called the wall reflecting the lake. There are two waterfalls hanging above the Longjing, hanging from the mountain stream. These are the Shuanglong Waterfalls.
