Introduction to Yue Gu Building: The floor plan of the building is approximately elliptical, but it is actually an upper and lower floor consisting of two semicircles on the left and right sides. The shape of the building is unique. Along the walls of the building are inlaid stone carvings of famous calligraphers from the Wei and Jin Dynasties compiled by Liang Shizheng and others, totaling 495 square meters. Emperors and empresses of the Qing Dynasty often came here to read and admire ancient calligraphy.
