浮光散去昔年已是苍桑含情脉脉回眸确是断肠
[fú guāng sàn qù xī nián yĭ shì cāng sāng hán qíng mài mài huí móu què shì duàn cháng]
Roughly meaning 'as the fleeting lights scatter, the old days have left only sorrow; glancing back with tender longing proves heartbreaking.' It speaks of nostalgia and heartbreak as past joys have dimmed over time and reflecting on them is profoundly painful and nostalgic.
