Why does it feel comfortable to write with a hard pen?

There is no difference between fingers and wrists. Don't be dull when learning calligraphy. To be precise, you should be calm when writing, and then concentrate all your attention on your arms, wrists and fingers. Wrist controls large direction and strength, and fingers need to be fine-tuned. Both are indispensable, otherwise the written words will definitely make people feel that something is missing! Be flexible and pay attention to flow. If we think too much, the words we write will be very lifeless and meaningless.
