Introduction to Yunguang Cave: Yunguang Cave is located on a flat land in front of Longjing Peak, where the scenery is beautiful and pleasant. According to historical records, during the Dading period of the Jin Dynasty, Wang Chongyang came east to teach disciples and founded the Quanzhen Sect of Chinese Taoism. Wang Chuyi of Dongmou worshiped him as his teacher and practiced Taoism. After completing his studies, Wang Chuyi traveled east to Chashan and came to Yunguang Cave, where he founded the Kunshan School of Quanzhen Sect. The famous "Yunguang Collection" was completed here. Because there are eight treasures in Yunguang Cave: ginkgo tree, wisteria, saltwater cave, Longquan Well, Immortal Bridge, stone carving tomb, tickle tree, and Bodhisattva temple, it is also called "Eight Treasures Yunguang Cave".
