Don't Assume It's a Compliment: The biggest mistake for learners is to use `多情` thinking it means “passionate” in a purely positive way, like in English. In modern daily conversation, it's far more likely to be interpreted as “fickle” or “flirtatious.” Complimenting your partner by calling them `多情` could easily backfire. Use
浪漫 (làngmàn) for “romantic” if you want to be safe.
