The most important thing is the teacher's ethics and qualifications! Then there is whether the teacher has experience and methods for young children. Then there is the price and distance. It is not recommended to go to a musical instrument store or training center, because the class fee there is relatively low (yours is definitely not cheap) and the time is tight. If you think the teacher in the music store is good, you can go directly to the teacher's house. Time is easier to accommodate, teachers are more attentive, and the quality is good.
