It's good to have jazz saxophone in the modern music department of Shanghai Conservatory of Music.

Sichuan Music Quartet of Sichuan Conservatory of Music is very good. Teacher Li Yusheng should be good.

The saxophone of Shenyang Conservatory of Music can also be Zhao Daguang.

I don't know much about others.

I hope it helps you. I always feel that the national instrumental music in the central region is not as good as that in Sichuan. Sounds good.

Jazz saxophone in Shanghai should be good.
