"Younger" foreign language school in Shenyang is a national chain, a regular foreign language training school, which is similar to what you said, and it is a small class taught by all foreign teachers, and the learning effect is very good.
You can listen to it first when you are free.
Younger is in Taiyuan Street, Shenyang Station, which is quite close to the Medical University.
Just take bus No.220 and get off at Taiyuan Street.
