Adults in Beijing learn piano, and the tuition fees are different according to the level and grade of teachers. Teachers who graduated from normal colleges have a class 100, teachers who graduated from professional colleges have a class of 200-300 yuan, and teachers who graduated from professional colleges have a class of 500-800 yuan, with a higher professor level. If adults are beginners, it is suggested that teachers in normal colleges can have one class (45 minutes). Tuition is calculated according to one class. If time permits, it is best to enroll in this study for half a year, or find a teacher for twenty or thirty classes at one time, so that the overall tuition fee is much cheaper after the discount.
