1. Professionalism of teachers: The higher the professionalism of teachers, the higher the cost. Of course, the more things students learn, the more professional guidance they receive.

2. Length of study: Is this mainly a short-term crash course, winter and summer classes or full-time study? The length of study time will also affect the cost.

3. Class form: refers to one-on-one private education, small class system and large class system. Among these forms, one-on-one private education is more expensive, because the one-on-one course teacher's concentration is only on you, so he can always focus on the students' dance movements and play a role in correcting them at any time.
