意味
Admitting lack of information
文化的背景
Hanoians tend to be more formal. Using 'Xin lỗi' is strictly expected when you cannot help someone, as it maintains the 'elegant' (thanh lịch) image of the city. Saigonese are more casual. You might hear 'Hổng biết' or 'Hổng rành' (not expert in). 'Dạ' is used frequently as a polite filler. In a company, saying 'I don't know' can be seen as a lack of competence. It is better to say 'Tôi không rõ, để tôi tìm hiểu' (I'm not clear, let me find out). Students are encouraged to admit when they don't know rather than guessing, but they must always use the 'Dạ... ạ' structure to show respect to the teacher's authority.
The 'Dạ' Rule
Always start with 'Dạ' when speaking to someone older. It makes 'I don't know' sound much more respectful.
Avoid 'Tôi' with Elders
Using 'tôi' with your grandmother or a teacher will make you sound like a robot or a rude stranger.
