Introduction to Huaiyuan Bridge: There is a ditch in front of the mountain gate of Tanzhe Temple, about two feet deep. There is a stone arch bridge on the ditch directly opposite the mountain gate, named Huaiyuan Bridge. The bridge is a single-hole stone arch bridge, 21 meters wide. It is 28 feet long. There are four stone railings on both sides of the bridge. There is a dragon head carved on both sides of the bridge arch overlooking the bridge. The shape is simple and majestic, beautiful and strong. Although it has gone through hundreds of years, it is still in use today.
