Ask a responsible piano tuning lawyer in Hefei to tune it himself.

I recommend Mr Wang Yi. My piano always had abnormal noise at first (later I learned it was called noise). The tuning lawyer recommended by the teacher failed to repair it seven or eight times, and then I was refunded the money for not repairing it. Later, when I saw Mr. Wang at a friend's house, I asked him to come home and help me adjust the tone. I didn't expect it to be fixed in a few minutes. Later, he also tuned our teacher's piano.
