海不会再深不会再亡天不会再晴不会再蓝
[hăi bù huì zài shēn bù huì zài wáng tiān bù huì zài qíng bù huì zài lán]
Translated into 'The sea won't get deeper again, never lost again; the sky won't get clear again, never blue again', it conveys finality after profound change—perhaps suggesting closure and the inevitability of transformation in emotion or circumstance.
