The image shows a display case with a piece of metal on it. The metal appears to be old and rusted, with a yellowish-brown color and a rough texture. It is resting on a clear acrylic stand with a white background. On the right side of the display case, there is a small plaque with Chinese characters written on it, which likely provides information about the metal. The plaque is likely a reference to the late Warring States period, as indicated by the text on the plaque.
