Introduction to East China Sea Wonderland: East China Sea Wonderland is located at the southern foot of Wangye Mountain. There is a natural sea erosion shaft with a diameter of nearly 50 meters and a depth of more than 40 meters. It is called the "Immortal Well". The walls of the shaft are steep and there are three small holes and the ocean at the bottom. Similarly, next to the "Immortal Well" there is a grand canyon that looks like a split in the middle of the mountain, which is called the Immortal Valley. Outside the valley is the vast sea. The bottom of the valley is covered with round pebbles, which are naturally formed by seawater erosion. Whether you look down from the wellhead or sit in the well and look at the sky, the scenery is very strange.
