The image is a photograph of a white paper with black text written in Chinese. The text is written in both English and Chinese characters. Below the text, there is an illustration of a ship with a shadow scale on it. The ship appears to be a replica of the Tomb of the Marquis of Ruyn, as indicated by the text at the top of the image.

The illustration shows the ship in detail, with the shadow scale clearly visible. The shadow scale is used to measure the depth of the ship's surface and the position of the Vernal Equinoxes. The illustration also includes a legend that explains the meaning of the colors used in the illustration. The background of the paper is plain white, making the text and illustration stand out.
