求翻译：但是我并不是专业人员，我从没在音乐大学学过音乐和钢琴，我会弹钢琴曲和教人们如何用正确的姿势弹钢琴，但是我对乐理的了解非常有限，所以我想请教你在你的音乐学校老师都教哪些关于钢琴和乐理方面的知识。是什么意思？

But I am not a professional, I've never studied music and piano at the University of music, I can play the piano, and taught people how to use the correct posture to play the piano, but I'm very limited understanding of music theory, so I would like to consult you in your music school teachers are to teach what knowledge of piano and music theory.
