Introduction to the Wanren Palace Wall: The "Wanren Palace Wall" screen wall faces Yundu, with a total length of nearly 100 meters. On the south side of the screen wall, there are four large brick characters "Wanren Palace Wall", each about 1 meter square. "Ten Thousand Ren Palace Wall" comes from "The Analects of Confucius: Zi Zhang Pian": "...the Master's wall is tens of (thousand) Ren high, and no one can enter through the door." It means to praise Confucius for his profound knowledge and very high level of moral writing. There is a brick workshop at each end of the palace wall, with three bays and three arches. The middle door is taller and has a brick-engraved banner on it. In the east is "Depei Tiandi" and in the west is "Tao Guanguanguandi". These eight characters were all written by Zeng Guofan.
