The cost of the guitar training class depends on the teacher, the number of students and the class hours. Usually, the more students, the lower the class fee, and the fewer class hours, of course, the lower. Usually, if the winter vacation is less than one month, classes will be arranged at most twice a week, with 6-8 classes each time. /kloc-students above 0/0, the class fee is 30, and the whole winter vacation is about 200.

However, I suggest that you don't go to a large class with more than three people, because instrumental music is not like other intellectual knowledge, and it is almost enough. Most of the instrumental learning is very detailed and needs very standard to continue. If there are more than three students, the teacher can't control it at all. Students can only learn theory, and technical problems are difficult to solve.
