Personally, I think the most important thing if you want to open a calligraphy class is not to mislead students. Teaching writing is the same as doing things. It must be worthy of one's own conscience, have real talents and practical learning, and allow students to truly learn knowledge and skills that will last a lifetime.
Calligraphy does not have obvious results in a short period of time like other skills. Therefore, when recruiting students, we must recruit students who really love writing and come to sign up voluntarily. We must not recruit students who come to study under the pressure of their parents, because there are no Interest, no matter how good you are in teaching, it is difficult to teach outstanding students. In other words, if your parents pay the tuition but cannot see the effect, would you accept it if it were you?
