Introduction to the Liang Ladder: The Liang Ladder was built in the Ming Dynasty on two cliffs in the east of the village. It has 28 steps in total. Each step is made of stone slabs about 1.5 meters long and 40 centimeters wide. One end is inserted into the rock wall and the other is suspended in the air. When it was built, each two levels opened up to each other, hence the name. On the pedestrian ladder, you can see the misty blue sky above your head, and the deep valley below your feet. It is scary, dangerous and strange at the same time.
