Man,You mean how to improve your English skill??There's no good English or bad English XD!
Honestly speaking,i suggest you to read English Newspaper daily.For Instance,SCMP(South China Morning Post.)I read it everyday so as to learn more new vocabulary,grammar and idioms,It really helps.
What's more,to speak fluently,you should always speak more,maybe with your fds.
