Introduction to the Urn in the Cave: On the stone cliff on the north side below Laojun's furrow, visitors can climb up to the top of the stone by stepping on the stone nest and holding the iron rope in their hands. They can only reach the entrance of the cave by crossing the single-plank bridge. They see a black glazed urn in the cave. There is also an urn inside the urn. The two urns are one and cannot be separated. It is called Wengli Weng. Many tourists are surprised by the small entrance of the cave and the large body of the urn. How to put the urn into the cave has become one of the top ten mysteries of Huashan.
