My daughter took small piano lessons in harmony for a year when she was 5 years old. After the second grade, I studied at Fengfengsheng Piano School. Now I have passed the piano amateur level 5. My friend’s son is very naughty and also studied at Fengfenshi (her mother introduced me to this school). Now I have reached level 8 and will take the exam in the summer vacation. It's level ten. Before the Level 5 exam, it was 40 yuan/class for half an hour, but now it is 50 yuan/class for half an hour. Once a week. Personally, I think the teachers at Prosperity are pretty good. There is a young female teacher named Lu Leyi who is very nice and very patient in teaching students. Some teachers will scold or hit others, which will make children feel bored and refuse to practice. But Teacher Lu has a very good teaching method. In fact, practicing piano is a boring process. The most important thing is persistence. My daughter stopped playing piano for two years and then was introduced to take classes at Fansheng. Now she has developed a good habit. So I suggest you go for Boom, or Harmony. Because these two schools have been open for a long time and have rich educational experience, some of the newly opened schools may lack teaching staff. Personal advice, hope it helps you.
