係即時翻譯無需安裝的

可以用Bing翻譯，唔使下載。(係即時翻譯)(要連線上網)

You can try a software named Babylon its on the market for a long time.

There haven't got 100% correct translation due to the terms on different usage after the software convert to chinese you still need to find someone to proof read it make sure all wording is what you need it to be.

Hope the information help!

Cheers!
