Introduction to Stone City: Stone City is located in a typical Danxia cave. The top of the rock slopes out. The recessed space under the rock can accommodate more than a hundred people. In front of the stone wall, there is a length of more than 50 meters and a base width of more than 50 meters. It is surrounded by a 1.5-meter curved city wall with three city gates. Outside the wall, there are clusters of Luohan bamboos and green trees all year round. There are cliff stone carvings such as "Stone City", "Youran Jian Nanshan" and "Ziyun Low" on the rock walls in the city.
