The image shows a small, rectangular object in a clear plastic display case. The object appears to be made of metal and has a dark brown color. It has a small knob on the top, which is likely used to open or close the object. On the surface of the object, there are Chinese characters written in white ink. The characters are written in a traditional Chinese script and appear to be carved into the metal. The background of the image is blurred, but it seems to be a museum or exhibition space.
