Star Cluster Cave

　　Located about 500 meters west of Zhongfengkou, roughly 3 kilometers south of Biyun Cave, it features two entrances facing northeast and an elevation difference of around 50 meters. The lower cave is commonly known as “Qingming Cave,” while the higher one is called “Doubing Cave.” The cave is collectively named “Star Cluster Cave” because of the pure, large calcite crystals inside that sparkle like stars under the light. The main passage extends about 450 meters southwest, connecting via a vertical shaft to Liangfeng Cave, forming a complete cave system.
