The image shows a piece of stone with a keyhole in the center. The stone appears to be old and weathered, with a rough texture and cracks on the surface. The keyhole is made of metal and has a small loop at the end. On the top of the stone, there is a yellow plaque with Chinese text written in black. The plaque is mounted on a beige-colored wall. Below the plaque, there are two smaller rectangular plates with Chinese characters written on them.
