姑娘若美若当年少年若青涩如初
[gū niáng ruò mĕi ruò dāng nián shăo nián ruò qīng sè rú chū]
The phrase describes reminiscence about youth, translating to 'The girl is as beautiful as in old times, and the young man remains innocent just like the first time.' This reflects nostalgia for past relationships when both were youthful and naive.
