What font is the most comfortable to read an e-book?

The larger the screen size of the e-book, the smaller the font needed to be read. Therefore, Song font, Song font, and bold font were more suitable for the reading experience. These characters were widely used on computers, so they were also suitable for e-paper books. In addition, clear and easy to read font is also very important for e-paper reading, so you can try to use some clear and easy to read font such as regular script, running script, cursive script, etc.
