There are three golden characters "Wenshu Yuan" engraved on it, which were written by Zen Master Cidu Haiyue of the temple during the Kangxi period. The yellow color indicates that this is the pure land of Buddhism. It is impossible for any demons and ghosts to enter the courtyard through this screen wall.
