Introduction to the screen wall: The screen wall is located outside the Confucian Temple, facing the Dacheng Gate to the north. The screen wall is 9.85 meters long, about 5 meters high and 0.95 meters thick. It is made of bricks in the shape of a "one" and has a glazed tile roof. There is a circular brick decorative pattern in the middle of the north side, which is a relic of the Qing Dynasty. It was saved from demolition for decades by its use as a fence.
