1, when reading, don't flatten the pages by hand, just spread them naturally.

2, need to record or stay in the middle page, the new book will automatically close because there is no paper hard, choose to use dry heavy objects to suppress, do not fold.

3. If you leave for a while, you can't remember the page number. Don't fold the corner on the page. Insert a bookmark or other flat tool in the middle.

4. Books you don't read are put on the bookshelf and sandwiched between a pile of books, so that the pages can be kept flat and not damaged by unexpected factors (water and dust).
