Practise! By the way, "improve my oral" sounds rather rude and funny in English. It's better to say "improve my speaking" or "improve my speaking skills".

You must visit English speaking clubs and other communities, English courses. Also you can speak oral on skype with your friends from italki, who want's to improve their oral either:)

To improve your oral what? There is "oral sex". This is probably not what you mean. ;) You wanted to write: "How can I improve my oral communication skills."

I think you should say more ! you can talk with Chiese friends,they can help you improve your Oral

What do you mean exactly? o_O
