The image is a photograph of a whiteboard with Chinese text written on it. The text is written in black ink and appears to be a description of a piece of wood. On the left side of the board, there is a black and white illustration of a tree trunk. The tree trunk is drawn in a sketch-like style and is slightly tilted to the left. Below the illustration, there are two smaller illustrations of the same tree trunk, one on the right side and one in the bottom right corner. The background of the whiteboard is a beige wall.
