丢了少年失了梦乱了夏天蓝了海
[diū le shăo nián shī le mèng luàn le xià tiān lán le hăi]
'Lost Youth, Lost Dreams, Disturbed Summer, Blue Sea' seems poetic and melancholic; it refers back to someone reflecting on losing important parts of their youth: ideals and dreams perhaps. This may also reflect on how these losses disrupt the peaceful or happy moments such as summer days by the blue sea, symbolizing a mix of longing and melancholy for the past.
