There are too many English trainings in Wuxi, Jiangsu, so we should make a good comparison. As far as my own situation and the English training institutions I have participated in are concerned, EF English may be more suitable for your situation. They offer English courses at all levels, depending on your personal English ability. In addition, the class time is more flexible. I think it's not bad, and I've made great progress, probably because these courses are more systematic and targeted.

You can attend their formal classes for free.
