How to choose a hard pen calligraphy teacher and a pen drawing teacher? Are teachers Wang Shu and Zhang Cheng teaching in Dalian?

I want to be a master, not a famous teacher. Some names are many, but most of them are not worthy of the name. Master is a teacher who really understands. For example, the teacher of Mo Lianzi (pen calligraphy crash course in Rizo, Dalian) has a good writing style and has been working in the front line for a long time. Teacher Wang Shu is Zhang Cheng's favorite pupil, and now he has founded @ Mo Lianzi. For details, please contact 858016795 @ q.
