The "Small Right-Angle Series Bookmarks" is designed for people who are busy and love reading. Due to the busy life of today’s people, the usual reading time is often interrupted by work and life. The small right-angled series of bookmarks have obvious decorative functions. Even if the books are put on the bookshelf, they are very conspicuous. It reminds you that you are still busy with reading. When the bookmark is re-used, it only needs to be added directly to the bottom of the page to secure the folder. When you finish reading, you can also place the bookmark on the edge of the bookcase and on the screen display, and become a good partner for your office. The theme of this section of the book is "Bevov Dragon". Its classic example is the Nordic legend from Beowulf. Bezuf was the first hero and king to kill dragons, but he also died in a fierce battle with dragons. It was tragic. The theme of this bookmark is the dragon's attitude, and it is precisely from time to time that he reminds himself like Beowulf to be brave enough to face the challenges brought about by life.
