姑娘眼睛多美不太适合流泪少年薄唇多软不太适合吮烟
[gū niáng yăn jīng duō mĕi bù tài shì hé liú lèi shăo nián bó chún duō ruăn bù tài shì hé shŭn yān]
This poetic line describes the beauty of a young woman's eyes and the tenderness of a young man’s lips. However, it also conveys that the woman should not cry, and the boy shouldn’t smoke. This reflects an idealized view of youthfulness and innocence.
