The difference between a brush and a pen. What is the difference in the meaning of practice?

Brush is soft calligraphy, pen is hard calligraphy. Brush can write thick and thin lines according to the position, direction and strength of the pen, while the thickness of the lines of the pen does not change much because of the nib, and it is two different ways to hold the pen.

Therefore, writing with a brush is not necessarily good. (But most practitioners know the importance of font structure to Chinese characters. So the writing brush is good, and the pen is not too bad. )

Pen can copy software characters, but mainly copy font structure.

The same font and font, written with pen and brush, are mainly different in content created by lines. A brush has more room for change on paper, while a pen is smaller. If you don't have a good command of calligraphy before, you'd better start with official script, which is easier to master. For beginners, Cao Quanbei is a good copybook for beginners to practice. Don't write regular script until you master and skillfully use the brush.
