Regarding the decoration of the library, a large part will choose content that is useful to children, rather than what style is required. For example, describe the season, month and safety on the wall, so that children can understand the instructions at the same time. The library is a place that pays more attention to details and environment. Too cold colors will make children feel empty. It is recommended to use warm colors, which have a warm feeling. If you still want to post something, it is recommended to use soundproof paper. In short, the primary school library, to put it bluntly, just lets children have a preliminary understanding of books, and lets children cultivate their sentiments and like decoration. If it doesn't work, you can do a survey before the renovation and ask questions to children of different grades. I hope it works for you.
