再怎么回忆那月亮也缺了再怎么怀念那天空也黑了
[zài zĕn me huí yì nèi yuè liàng yĕ quē le zài zĕn me huái niàn nèi tiān kōng yĕ hēi le]
However much I recall, the moon still wanes; no matter how much I reminisce, the sky darkens - This phrase indicates the inevitability of loss or change even amidst attempts at preserving memories and moments of happiness, highlighting bittersweet nature of time passing
