Panlong Cave Introduction: Panlong Cave is one of the seven dragon caves on Yishan Mountain. The four characters "Panlong Cave" on the stone wall at the entrance of Panlong Cave were written by Wang Zijin during the Wanli period of the Ming Dynasty. There are eight wonders in the cave: the cold spring in the empty valley, the ear-cleansing spring, the mysterious and far-reaching stream, the light everywhere, the hourglass in the sky, the sunrise with three poles, bell stones and bell stone inscriptions. The most magical one is this bell stone. Panlong Cave is very deep, with nine twists and turns inside, with every step leading to a scene and a spring.
