hey friend. just talk to others especially native speakers as much as possible. during this, you can learn the way they think, talk and the way they express, then you can use what you learned next time when talking with other...yes just talking, practising

The secret is 'fun'. You won't have fear to a funny thing. So don't study it, try every way you can imagine to make english funny to you. As you keep using english, it will naturally improve, and you will master practical english. Instead of havling a lot of difficult and useless english words in you mind.

Hi Chen , you can always try to work in a company where you can practice English everyday, that way you will become more confident.

Hello Chen The problem with languages is that you have to practice to be able to speak when it is necessary. Here on Italki you have this opportunity to connect with a lot of different people and you can share your knowledge with them. Or you can take some sessions with a teacher who will be able to guide you and help you with your speaking skill. Look on the left hand side and click on "languages teacher" if you want.

兄弟，何不让我们从头再来？
