Recently I've asked "How do we choose the correct characters for a westerner name?", and now, I'm facing a similar, yet kind of different problem, which I think applies to any westerner or Chinese student at a beginner level.
There are two exercises that ask to translate some sentences, which are not that hard, thanks to the glossary, but I've faced a small, nonetheless daunting difficulty, which is the translation of Chinese names.
When I have to translate a sentence like "Mr. Hu/Huang/... is a lawyer", how do I know which character corresponds to that name? Are there any guidelines for selecting the right character (apart from asking the person directly)?
