The East China Sea Wonderland is located in the south foot of Wangye Mountain. Here, there is a natural sea erosion shaft with a diameter of nearly 50 meters and a depth of more than 40 meters called the "Xianren Well". The wall of the well is steep and there are three small holes at the bottom of the well that connect with the sea. There is a Grand Canyon cracked in the middle of the mountain next to the "Xianren Well", called the Xianren Valley.
