心死不能复生
[xīn sĭ bù néng fù shēng]
'Dead heart does not revive,' indicates emotional trauma, despair, or resignation to a dead-end situation. In the metaphor, 'dead heart' could be seen as the failure to regain the courage to fall in love again, losing faith in people, events, systems, or ideals due to previous disappointments. It portrays a heavy sentiment of having been hurt so deeply that optimism and hope seem beyond reach.
