Introduction to Fairy Cave: Halfway up the mountainside of Yanglinjian Peak is a marble cave that is rare in North China. The entrance is 2.5 meters high and 5 meters wide. Less than two meters into the cave, there is a small cave. The cave is about 30 meters deep and merges into the large cave, hence the name "Fairy Lovers Cave". The cave is sometimes wide and sometimes narrow, sometimes high and sometimes low. The wide part is like an open hall, which can accommodate hundreds of people gathering. The narrow part can only be walked sideways and with bowed heads. This cave is connected to Pingshan Qiubo Cave and is 15 kilometers deep. The huge rocks hanging in the cave have strange shapes, like humans and apes, which are quite spiritual. Ancient swords and alchemy furnaces have been excavated. The locals call it the "Fairy Cave".
