The sea-in pool in Puji Temple in Putuo Mountain was built in the Ming Dynasty. The pool water was accumulated by mountain springs. The lotus blossoms were grown in the pool. The lotus blossoms were clustered in summer. The whole pool water was covered with greenery and the scenery was charming. There are three stone bridges on the pool, connecting Puji Temple Zhongshan Gate, Octagon Pavilion and Yubei Pavilion on the same central axis. This is a classic view of Putuo Mountain.
