Scientific calligraphy practice

If it doesn't work, talk less, choose posts, etc. You don't have to answer. I suggest seeing Mr. Qiu Zhenzhong's calligraphy practice, which is the most scientific way to practice calligraphy. Start with the basic movements. It doesn't matter what position you choose. If you do the basic movements correctly and learn what you like, the rest will be very easy to complete. For example, the most important thing in calligraphy is to lift the wrist. If you can tell the size of an egg with your wrist, you shouldn't use your arms or your fingers. In this way, the center is naturally successful, and the lines are thick and textured. Is it difficult to do anything else?
