Chinese languages

Many thanks duaaagiii for your reply. How do you get these information? Is there a web site?
I really like to learn to be able to do this.

Hi, I have been looking through this forum but don't quite get it. I like to find out how to romanize a hokkien's chinese name in english. I know 吴 converts to Goh. How about these characters 思敏， 思铮， 满婷? I could not find a chart or web site that I could reference. Hope someone could help assist me.
