The image shows an old, weathered cannon displayed in a glass case. The cannon is made of metal and appears to be old and weathered, with a dark grey color. It has a cylindrical shape with a pointed end and a flat base. The body of the cannon is covered in dirt and grime, indicating that it has been exposed to the elements for some time. There are two small black stands on either side of the body, which are likely used to hold the cannon in place. A small plaque with Chinese characters is attached to one of the stands, likely providing information about the cannon.
