Introduction to Gongbao Stone Village: Gongbao Stone Village was formed by the fall of fault rock on the mountain wall. In the past, there were several stone houses. The terrain is dangerous, easy to defend and difficult to attack. The entrance of the village is hidden. There used to be a gate and a doorway. It is about 1.6 meters wide and 7 meters high. Standing guard at the entrance of the cave has the effect of "one man can guard the gate, and ten thousand men cannot open it".
