What's the difference between the horizontal version and the vertical version of traditional books?

The difference between vertical and horizontal calligraphy is that the first writer in ancient times usually wrote vertically from right to left, and the center of gravity of the words was basically on a vertical line, paying attention to the white cloth from the side to the back.

Second, modern people generally write horizontally from left to right. Of course, in order to create calligraphy, people nowadays imitate ancient posts and can also write vertically.

Three-point vertical calligraphy is like a picture scroll unfolding slowly, which is easy to resonate with the appreciator and can better reflect the beauty of calligraphy. Horizontal writing is suitable for modern hard pen writing, not as smooth as vertical writing.
