Introduction to Liaoer Stone: The stone looks like a large "crystal stone", 5.2 meters high and 5.6 meters wide. Legend has it that an old lady often stood on this stone because she was looking forward to the return of her son who was practicing cultivation on the mountain, hence the name "Liao'er Stone". It is located 800 meters north of Wushengtang, on the roadside of Shiliuyu.
