Kunshan Huaqiao? If it is junior high school or senior high school English, KT English is the first to be promoted, or the English savior. That teacher is very famous and has a set of learning methods, which can improve self-study ability. Children have tried it, and the effect is really obvious. If it is adult oral English or business English, you can try Maya English.
Learning methods and introduction are the key. Personally, if you have the ability to learn by yourself or have mastered the thinking mode and method of English learning, you can learn by yourself. There is no need to go to training classes.
