Introduction to Penglai Xiang Cave: Located between the valleys on the left side of Huafeng Rock, it is a large magical cave made of travertine, which was called "Xian Cave" in ancient times. A clear spring emerges from the cracks in the rocks, which is called "the first spring in Hainan". It is the "original spring" given by the Jade Emperor to nourish the Qihuayao grass here. There is also a Mandarin Duck Pond under the spring. The spring water in the pond can cure diseases and keep fit. .
