The image shows a stack of books on a wooden shelf. There are nine books in total, arranged in a pyramid-like shape. The books are of different sizes and colors, with the topmost book being yellow, the middle one being white, the bottom one being red, and the bottom two being black. Each book has Chinese characters written on it, which appear to be related to the year 1997-2008. The titles of the books are written in both English and Chinese. The shelf is against a beige wall, and there is a red fire extinguisher visible in the background.
