心死什么温暖都白费
[xīn sĭ shén me wēn nuăn dōu bái fèi]
Translating to 'if one's heart has grown cold/dead, then warmth is of no use', reflects deep disillusionment and indifference; feeling too emotionally numb to respond positively even to kindness, indicating hope lost or feelings frozen by negative past experiences.
