giàu vì bạn, sang vì vợ

Vietnamese

(literal) men tend to act rich to their friends, classy to their wives
(figurative) men tend to put on different façades when dealing with their friends and their wives
(literal) men are rich thanks to their friends, classy thanks to their wives
(figurative) friends and wives are invaluable to men

Since vì could mean either "for the sake of" or "due to", there are two interpretations of the same phrase.
