The entrance hall, named Zhihua Gate, is a small structure with three bays across the front and two bays across the depth (13 x 7.8 meters). It originally contained four now-lost statues of the Four Heavenly Kings installed to guard and protect the temple. Taken together with the Drum Tower on the west and Bell Tower on the east immediately inside the entrance gate (shanmen), the first quadrangle serves as a preparatory space before one makes entry into the main part of the complex to venerate the Buddhas.
