Introduction to the Heaven-turning Seal: There is a stone platform on the top of the cliff. There is a huge stone that is like a giant seal placed upside down on the platform, so it is called the Heaven-turning Seal. Since ancient times, people seeking official positions have kowtowed here to pray for their wishes. This stone is about 3 meters high, with a large top and a small bottom. The top is a 2-meter square platform, and the smallest part at the bottom is only the size of two people hugging each other. It looks like a giant oyster mushroom up close and like a large seal pointing up to the sky from a distance.
