The main body of Yanxiang Lou is 40m in diameter, with 1.5m-thick bottom wall, 0.7m-thick top wall and 14.5m-high wall. The main building was constructed according to the Eight Diagrams. With wing rooms on the left and right sides, the inner hall imitates the mansion-style building, including the back hall, the nave and the front hall. The walls, left and right doors inside and outside the hall are ingeniously carved, and the calligraphy and paintings on the walls are exquisite. The overall layout of Yanxiang Lou is harmonious, unified, beautiful and practical.
