What should students do if they want to learn calligraphy but find it expensive?

If it is a one-on-one class, 60 is not expensive at all. If it is a group class, it may be a little more expensive, but the specific analysis depends on the teacher's level. The first consideration in teaching is the teacher's level. If the level doesn't reach a point, it will be cheaper, even if it doesn't cost money. High level is the first factor, including professional level, ability to explain, and whether the class characteristics are suitable for this student. On this basis, see if this level is worth the money, and then consider your own economic situation. As for the level of teachers, don't simply think that "I haven't studied, but I don't understand". This is an artistic aspect, not math and physics. As long as you are artistic, even if you haven't studied it, you don't have to tell the difference between good and bad.
