Introduction to Lema Cliff: The legend of Lema Cliff is even more magical. This deep stream did not exist in the past, and the mountains on both sides are connected. When Wang Mang rode here, the horse suddenly jumped into the air with its front hooves and threw Wang Mang off. Suddenly there was a thunder in the sky, and Wang Mang watched as the mountain in front of him collapsed and turned into a deep cliff. Some people say that this is God's warning to Wang Mang: he should rein in his efforts; others say that an earthquake happened to happen, which was a coincidence.
