‘Āi shēng tàn qì’ literally combines four characters: ‘āi’ (a sighing interjection), ‘shēng’ (sound), ‘tàn’ (to sigh), and ‘qì’ (breath or air). Together, they form an idiomatic verb meaning to sigh repeatedly—often with a slumped posture or downcast eyes—to express deep dejection, frustration, helplessness, or weariness. It’s not just one sigh, but a habitual, audible pattern of sighing that reveals inner emotional exhaustion.

This phrase is commonly used in spoken and written Chinese to vividly portray someone overwhelmed by misfortune, disappointment, or chronic stress—such as failing an exam, facing financial hardship, or enduring long illness. It carries a slightly literary yet conversational tone and often appears in narratives, dialogue, or descriptive commentary. While it evokes sadness, it’s more about passive resignation than active grief or anger.
