丢了少年失了心乱了夏天蓝了海
[diū le shăo nián shī le xīn luàn le xià tiān lán le hăi]
'Lost the youth, lost the heart, disrupted the summer, blue (saddened) the sea' conveys a profound sense of loss and nostalgia. The speaker mourns for youthful days and loves passed, which seem to have left the world disarrayed, turning once vibrant scenes somber.
