The image is a photograph of a transparent mirror, which is a type of decorative mirror. The mirror is displayed on a white board with Chinese text written on it. The text explains that the mirror is a mirror of the Western Han period, which can reflect an image, but when held to reflect a beam of light, it can throw onto a wall and magnified the image of the decorative pattern and inscriptions on its back. The image also shows a circular design with a central medallion in the center. The design is made up of a series of concentric circles, each with a different color and pattern. The colors range from light blue to dark blue, and the patterns are arranged in a way that creates a sense of depth and dimension. The background of the image is blurred, but it appears to be an indoor space with other people in the background.
