Introduction to Linyutan: Linyutan is also known as the Water Pearl Curtain. Its rock system is called Fengli Peak, which resembles a stone phoenix standing upright. There is a cannon hole in the opposite rock wall, and the echoes of the cannons shake the sky. The shape is there, very much like a stone phoenix singing in the sky. Chen Xiangdao, a Jinshi of the Song Dynasty, once studied here and wrote a poem about the scene: The east wind is floating on Buddha and the rain is slender, blowing from the air and touching the grass and trees. I remember the announcement of the Three Palaces Day, and the bead curtain was half scattered in the sky.
