Haiyin Pool is located here in Puji Temple in Putuo Mountain Scenic Area. It is a large pond, separated by a stone bridge and a Zhengyu monument in the middle. The pond is full of lotus flowers and is very beautiful. This place was originally a release pool, probably because there were too many releases, and a sign was erected next to it to prohibit release, and it was also to maintain the ecological balance in the pond. However, stop here to enjoy the beautiful scenery, behind the bells and aroma of the Buddhist temple, which is a pleasure for the soul.
