Why do you have to hang a pen when writing brush?

Because there are several advantages: 1. The written words are neat and beautiful. It is easy to control the strength when writing. 3. If you write horizontally instead of hanging a pen, the hair of the pen tip will be scattered, and the written words will be vague, untidy and unsightly. Actually, there is no need to hang up the pen. Su Shi, a famous painter, only wrote with a horizontal pen, but he wrote heroism with a pen. The most important thing in writing is to concentrate on the nib and control the brush with your arm. It's no use hanging a pen if you can't use your strength well.
