A year ago, my situation was similar to yours, and my English foundation was almost zero. My friend recommended it, and my friend said that Beijing is very cost-effective. I went to wizbee for English consultation, and their course consultant was very patient. I spent an afternoon consulting him that day. I have studied for almost 1 year now, and now I can communicate with foreigners (foreign teachers) basically without obstacles. You can also try. I hope you can learn it soon.
