懵懵懂懂的小青春兵荒马乱的小时光
[mĕng mĕng dŏng dŏng de xiăo qīng chūn bīng huāng mă luàn de xiăo shí guāng]
This refers to the confusing and chaotic yet precious times during one’s youth. '小青春' (little youth) refers to adolescence, a time filled with innocent dreams, confusion, and adventures; '兵荒马乱的小时光' evokes an era or time when things are chaotic but also meaningful in retrospect.
