Introduction to the Tiancheng Urn: is a typical representative of the unique landforms of the northern mountains. It has high value for geological examination and tourism. On cloudy days, the place is surrounded by auspicious clouds. Holding the railing, it feels like a dream, like entering a fairyland. It comes naturally; on a clear day, you can climb the ladder and plank road, admire the strange peaks and rocks along the way, walk flatly against the blue clouds, and suddenly feel like you are embracing the moon for nine days; in the rainy season, the three waterfalls flying down the southern cliff are very spectacular.
