I hear it is taboo to call any family member by their given name, especially if you are speaking to an older relative. Or if not taboo, then at the very least it is extremely rude. Do people ever call their mom/grandmother/aunt by their given name to disrespect them on purpose? Like in movies or something? Or does nobody ever do it at all?
In English I have heard kids call their parents by their name as a joke, or if they are feeling very hateful and bitter towards their parents. I also know someone who calls their aunt by name (just Kim, not Aunt Kim) because they are not close at all, basically like strangers. I wonder if you can do the same in Chinese or if it is more offensive than in English.
