If you want to learn spoken English, you can try the Midland English training class recommended by my colleague. I have participated in it, and I think American English is quite good. There is no time limit. You can attend classes anytime, anywhere, without worrying about being late or attending classes. It is more convenient to attend classes. Moreover, he also adopts the teaching form of one-on-one oral training and counseling, which can stop teaching your oral English in a targeted way. One-on-one class mode will give you more opportunities to practice oral English, eliminate the influence of your mother tongue and correct pronunciation mistakes. If you want to learn spoken English, Midland English is a good choice!
