It's best to find an excellent training school to sign up for a remedial class, otherwise you will take a lot of detours.
Friend, are you in Taiyuan?
If you can come to Taiyuan, I recommend Taiyuan Foreign Languages Institute, which is the largest foreign language training base in Taiyuan, with eight foreign languages: English, Japanese, Korean, French, German, Russian, Italian and Spanish.
There are new classes every month, including daytime classes, evening classes, weekend classes, winter and summer classes, all of which can be auditioned for free.
