Font problem of hard pen calligraphy

1. It has something to do with pens. But it's mainly a matter of skill.

2. Turn the pen to adjust the direction. In general, it is to achieve the effect of "thickness on copybooks".

According to the size of the words you write, the words in the hard pen are generally very small, and you don't need a wrist. But on the whole, I still follow my own habits.

All the above are personal opinions, I hope to help you.
