I don't think anyone has ever objected to puns here. There's a pun tag with some 250 sentences so marked. It would be interesting to learn some Chinese puns, which must be numerous given its logographic writing.

An addition: "do", Chinese much less commonly use a generalized verb like English "to do".

Without knowing Chinese, some possibilities, in no particular order:

1. Leave the difficult sentences untranslated. Maybe you have a better idea when you meet them in the future, and there is no lack of English sentences to translate, not to speak of other languages.
2. Look at other translations of the sentence for inspiration. (But be careful to add any translation to the sentence it is a translation of.)
3. Consider a context for the original sentence, and then consider how you would or could translate the entire context, and then check if that creates a valid translation for the sentence in question.
4. To translate "He loves her." into Finnish, I have to do some maneuver like "he" -> "man/boy" or "she" -> "woman/girl", as "he" and "she" both translate to "hän", and "Hän rakastaa häntä." is a somewhat strange construction. I do consider these various variations with man, boy, girl or woman to be acceptable translations.
5. English has constructions like "There is a car in the garage.", where the "there is" part has no equivalent in Finnish, so this would simply become "Autotallissa on auto.". The structure of the sentence is different, but the meaning is the same. A valid translation.

We did receive the e-mail, which you sent five days ago. It's quite possible that the person who takes care of audio has been too busy to respond yet. I would give him more time. I sent him a note mentioning that you had posted here on the Wall as well.
