Guanyin Ancient Cave is located on the stone side of the mountain after the Putuo Mountain Meiling in Zhoushan City, Zhejiang Province. It was originally a natural cave. There are no temples, only a few plum trees, so it is also known as "Gumeiling". The main existing Buddhist buildings are the main temple; the important cultural relics are the Guanyin sitting statue and the "25-round pass" group statue. The main hall of Guanyin Ancient Cave is rectangular, and there are 25 round-shaped statues inside.
