Introduction to the Wanzhang Monument: The Wanzhang Monument is located at the concave intersection of the ridge lines of Longshan Mountain and Hushan Mountain just north of Xiantong Temple. The original monument is about 2 meters high, 56 centimeters wide and 20 centimeters thick. The front and back sides of the monument are shaded. The seal characters engraved with "Zhushan Wanzhang" and "Namo Ami" were the boundary monuments of the three provinces of Jiangsu, Henan and Anhui. They were destroyed during the "Cultural Revolution". Now there is a stone monument nearby, with the words "Green Mountain" engraved on it. Climb the place where the monument is erected, and you can overlook the panoramic view of Huaibei.
