yeah, by that time he really had some Private studens,you must suffer alot the hard time from him, he's strict teacher but excellent, he die more than 10 years already, thank you ssh !
may I ask which summer you took your private lessons ?
I am saddened that Mr. Liu had already passed away. He was a good man. I took private lessons with him in the summer of 1975. He was actually quite nice to me.
Mr. Liu's nephew was also a good 高胡 player. After I returned to Taishan, I went to his house on 通濟路 numerous times to learn from him. I don't remember his name any more. Are you related to him?
