What the author writes on the bookmark.

1. The writing requirements on the bookmark are: when writing vertically, write from right to left, with even spacing and aligned upper and lower characters.

2. Pay attention to the position of the author's name to make the format more beautiful. Bookmarks used to write book titles are generally posted on the upper left corner of the cover of ancient books, and bookmarks used to write names and mark reading progress are generally made into small pieces and sandwiched in books. With the development of the Internet era, electronic tags are derived to record reading progress and experience.
