流年染指经不起的伤浮生衬着调不起的情
[liú nián răn zhĭ jīng bù qĭ de shāng fú shēng chèn zhe diào bù qĭ de qíng]
The fleeting years have left wounds too profound to bear, and the ephemeral life highlights the emotions that cannot be tuned or adjusted. This implies a bittersweet nostalgia for past hurts that are intertwined with unchangeable sentiments.
