久溺深海冷不冷长居悲痛累不累
[jiŭ nì shēn hăi lĕng bù lĕng zhăng jū bēi tòng lĕi bù lĕi]
The phrase 'If I were to drown in deep seas for too long, would I feel cold living permanently in sorrow, would I feel weary?' expresses feelings of prolonged emotional pain, suggesting that the person might be submerged in grief for a long time without respite.
