Introduction to Jianmen Strange Stones: Jianmen Strange Stones are located at Jinfeng, the highest peak of Yushan Mountain. The cliff here is a huge cliff, but the middle suddenly cracked, like a knife cutting with a sword. It is said that King Wu Fu Chai split it here when he tried his sword. The top of the crack is as narrow as a crack in a door. The narrow spot is only about two feet. There are huge boulders crisscrossing each other. It is amazing that it is about to fall in the air but does not fall.
