Introduction to the ruins of the military residence: The ruins of the general residence were the general residence for junior officers who guarded the Great Wall. Although it covers a small area, the original building was very grand. There are three exquisite stone carvings existing at the site, two of which are drum-shaped flagpole seats located on the left and right sides of the front door of the mansion, and the other is a decorative stone in front of the mansion door. Next to the ruins of the general's residence is the ruins of the "Pavilion Barrier". The walls of the "Pavilion Barrier" are made of rammed loess.
