The Mandarin Chinese phrase '难道 (nándào)' is used to indicate disbelief, doubt, surprise or to pose rhetorical questions. This phrase essentially infers 'Could it be that' or 'Is it possible' in English. It puts strong emphasis on the sentiment of the speaker, usually exhibiting shock or disbelief about a certain event or circumstances. Unlike normal questions, sentences with '难道' do not necessarily expect for an answer.
