The two ruins are located 18 km from the border between China and the State of Mongolia, and expand to the territory of Mongolia. The interior wall is as tall as a six-storied building, while the exterior2 wall is a little taller. The top of the walls are 2.3 m wide, and the top part itself is 1.15 m tall.
The walls were built of rocks from nearby places, and stuffed with sand. Long time of erosion has pushed the rocky part to slant3 to the middle. Several stone pits have been discovered in the mountains next to the walls.
Not far from the walls, the ruins of a beacon4 tower were found, which was built with similar material and technology to the walls. Now, its southern wall has become a part of a cottage.
