I suggest you go to an institution with a small class. Oh, you can go to Peiwen. Small class teaching is highly targeted and the teacher is very responsible. It's embarrassing to make up lessons for free if you don't attend class. Finally, the learning effect is very good. I don't think it's important to choose schools and brands. The most important thing is that teachers follow up in time and teach well. Peiwen never does any publicity to support this organization.
