You can go to the musical instrument store. Generally, a musical instrument store takes 5~ 10 yuan for one hour. You can also learn from the teacher in the musical instrument store. An hour is about 120. This piece of music you said is not difficult. I have been learning piano for eight years. If you find a more responsible and better teacher and practice by yourself, you can learn it in almost a month. But playing the piano is a very hard thing, it depends on whether you can persist.
