Introduction to Tianmen Pass: Tianmen Pass is lined with dangerous rock walls and towering cloud pillars. It is said that people who pass through this pass can reach the heaven, so it is named "Tianmen Pass". When you climb the pass and look out, you can see the clusters of peaks. Whenever the clouds and fog roll around, the peaks and cliffs are slightly exposed, like a mirage or Yaolin's fairyland. There is a turtle stone (seal stone) nearby. There is a series of footprints on the back of the stone. It is said to be the original work of an immortal. The top area of ​​the turtle stone is only the size of a table. It is said that it was a place where immortals from all over the world played chess.
