凉了时光病了心脏留了少年
[liáng le shí guāng bìng le xīn zàng liú le shăo nián]
'Time fades away, sick at heart, remaining a youth.' A poetic line implying sadness or depression ('凉' literally 'cool/chill') affecting the writer emotionally and physically as time passes, keeping a memory of someone or some period ('少年' refers to young age, but not just in terms of years old, it represents a more precious and pure time).
