The origin and function of bookmarks;

Bookmarks originated in the Spring and Autumn Period and the Warring States Period, when they were called "toothpicks". Made of bamboo, whenever you see a very important place in the book, you will insert a "toothpick" at one end of the book for easy reading. Bookmarks are even more useful when scroll books become folded books. After the Song Dynasty, more and more attention was paid to bookmarks, and sometimes sentences such as aphorisms were handwritten on bookmarks. Today's bookmarks are printed with poetry aphorisms, celebrity aphorisms and decorative paintings, which is the reason.

Now, we not only use bookmarks to mark the progress of reading, but also use bookmarks to record our reading experience and write comments. Bookmarks with books echo the traditional aesthetic principle of China, just like wearing a suit and tie, a book with bookmarks is a complete book.
