姑娘眼睛多美不适合流泪少年薄唇多软不合适抽烟
[gū niáng yăn jīng duō mĕi bù shì hé liú lèi shăo nián bó chún duō ruăn bù hé shì chōu yān]
Translated to 'a girl's beautiful eyes are too pretty for tears, a boy's delicate lips too soft for smoking'. This contrasts beauty with harmful behaviors and implies that one should cherish their grace and purity rather than tainting it with negative actions.
