姑娘眼睛多美不该拿去流泪
[gū niáng yăn jīng duō mĕi bù gāi ná qù liú lèi]
'The Girl Has Such Beautiful Eyes, They Shouldn't Be Used for Crying' expresses a poetic lament over someone beautiful being sad. It's a sympathetic plea to a young woman not to waste her beauty on crying; rather, she should remain joyful. The implication is that there may be something or someone causing her unhappiness.
