What's the use of writing hard pen calligraphy?

Calligraphy has been an art that can be appreciated for thousands of years.

Hard pen calligraphy is really useless now.

Mainly able to:

First, cultivate self-cultivation and cultivate sentiment.

Second, exchange ideas.

Third, being able to write a good hand outside is also my own face.

Fourth, keep a diary, weekly diary and memorabilia in your notebook. Looking back at comfort, you can also recall the scene and mentality at that time.

-To sell money? It's hard to say, haha.
