After all, choosing an excellent and responsible studio can save you a lot of detours in the art college entrance examination, so you need to be careful.
Personally, I don't like big studios. Although the learning atmosphere is stronger, after all, a teacher can't take care of dozens of students. Learn methods in large classes and learn things in small classes.
I suggest that every family try it for a few days and compare which teacher speaks it well.
Highly recommended: Blue Studio and Quyi Studio have strong teachers.
