Is it normal to have a wrist pain or not to have a wrist when practicing calligraphy?

It's normal to have a sore wrist when practicing calligraphy. Depending on the situation, you may be practicing calligraphy. I don't know how long you have been practicing. Estimated time is not long. You should pay attention to the correct posture and practice slowly. At the beginning, the time should not be too long, about half an hour is enough. It can be extended for 5 minutes after one week, and so on. It can be extended or not after 1 hour every day, depending on your own situation.
