丢了少年失了心丢了少年失了心
[diū le shăo nián shī le xīn diū le shăo nián shī le xīn]
'Lost Youth and Heart' (Repeated twice for emphasis) means one has lost both their youthful self and heart along the way. It describes a regretful loss of innocence, energy, and feelings, suggesting an inability to recover those aspects after growing up.
