Bookmarks are simple.

1. According to your own preferences, prepare a square piece of paper with any size, color and pattern.

2. Fold the paper in half, then open it, fold the other side, and then open the folding cross.

3. Fold the paper diagonally in half again. After opening, the other side is also diagonally folded in half, causing herringbone marks.

4. Fold the lower corner into a triangle after opening, and fold the folded triangle diagonally again.

5. The left corner is easily folded inward along the crease, and the right corner is also folded inward, and a bookmark is completed.

Bookmarks are used to indicate the title of a book. Generally, they are posted on the upper left corner of the cover of ancient books, and generally indicate where to read and record the reading progress. With the development of the Internet age, e-books which record the reading progress, experience and reading position have emerged.

As a sign of reading progress, we don't care too much. In fact, if you pay attention, in fact, a small bookmark will often vividly record the past life. It is like a mirror, from which we can see a thousand years of culture and all kinds of life.

The ancient scrolls brought bookmarks. In order to distinguish the contents of books and make them easy to read, the ancients tied a small card at one end of the shaft with the title and the number of volumes written on it, which is the embryonic form of bookmarks.
