Of course, I'm looking for an institution. Will a really good teacher come to teach you so casually? People are waiting in line for classes, and most private teachers are part-time. I dare not say that they are all unreliable, but most of them can be said to be unreliable. Of course, institutions have to find reliable and larger institutions. I think Qin Chao is bigger and more reliable in Xiamen. Their home has been in Xiamen for more than ten years. It is a piano training center with a brand chain and has won many competitions. . I hope my answer can help you. Take it.
