Introduction to Bailong Cave: Bailong Cave is located next to the Yudai Bridge at the foot of the northwest mountain of Jinshan Mountain. It is said that Lingtan, the great nephew of Wu Zetian of the Tang Dynasty, came to Jinshan and meditated in this cave. The white snake escaped and the poisonous gas disappeared. Now there are two white stone statues of Bai Niangniang and Xiao Qingqing from "The Legend of White Snake" in the cave.
