Penglai Xiandong has a large volume, rich layers and unique landscape. The total length of the cave is more than 3,000 meters, and the area occupied by the cave is more than 20,000 square meters. It has a history of more than 90 million years. Standing outside the cave, looking inward, the small hole is dark, but full of mysterious atmosphere. Entering the cave, the lights inside are colorful, like entering a fairyland. Due to the internal movement of the earth, the seawater has fallen, the land has risen, and the stalactites that have been eroded into different poses are now in front of us. The first thing I saw was the lotus platform, where the layers of stalactites were superimposed, like the tower that was formed by the opening of the lotus. Next is the Ganoderma Lucidum, which is also named after the shape of stalactites. The stalactites grow from the bottom up and spread out at the top, like Ganoderma Lucidum. Walking into the cave, not far away, you can see that there is a spacious path in the cave for tourists to watch on foot. The cave has different shapes of boulder and endless underground river. The middle hole is full of beautiful stalactites. If the object is a human being, it will be vivid and beautiful; the cave is magnificent and magnificent, and the twists and turns are deep and the landscape is strange. Standing on the path, looking up, the stalactites of various shapes and bumps are sighing, like walking into a maze. The twists and turns, the shape is peculiar. Looking forward, Xiandong is mysterious and amazed, making people have to explore forward.
