凉了时光病了心脏老了少年
[liáng le shí guāng bìng le xīn zàng lăo le shăo nián]
'The times have turned cold, the heart has fallen ill, and the youth has grown old.' This is a melancholic statement reflecting on how times and personal experiences can make someone feel emotionally hurt, worn-out or matured quickly beyond their actual age.
