Originally named Bagua Tower, it was named after the installation of a Bagua caisson inside the building. The Xieshan roof with three eaves and two floors is 17.04 meters high and divided into two floors. The overall building is composed of three parts. The south side is a half memorial archway, and the middle is a pavilion with three eaves and two floors. The ound ridge roof with back eaves forms the second stage in the Guanmiao Temple, which is very rare in the Ming and Qing dynasties.
