Introduction to Yanzi Cave: Yanzi Cave is located above the Qijie River. It is developed in the dark gray medium-thick dolomitic limestone of the first section of the Yongning Town Formation. It is 1040 meters above sea level. The entrance of the cave is trapezoidal and the top edge is about 60 meters wide, 68 meters wide at the bottom, and about 50 meters high.
