How long does it take for zero-based calligraphy graduate students?

Anyway, I think calligraphy seems to be an art of self-cultivation and there is no need to take an examination. Since it is necessary to cultivate, it is certainly not that easy. Learning calligraphy is not a form of light, but more importantly, learning its spirit. In the process of relearning, you can master your own skills and improve your aesthetics. It has something to do with your values, world outlook and outlook on life. . . Very influential. In fact, the art of calligraphy is to deal with the emotional accumulation of oneself or the outside world.
