The image shows an old cannon displayed on a wooden stand in a museum. The cannon is made of metal and has two large wheels attached to it. The wheels are made of wood and have a curved shape. The body of the cannon is cylindrical in shape and appears to be made of a light-colored material. There is a small plaque on the right side of the stand with Chinese characters on it, which likely provides information about the cannon. The background of the image is a white wall with a tiled floor.
