好伙子夜夜不休好姑娘永垂不朽
[hăo huŏ zi yè yè bù xiū hăo gū niáng yŏng chuí bù xiŭ]
'Good guys don't sleep while good girls live forever.' This is an ironic expression of night life culture, implying the liveliness and vigor associated with young people staying up late and being engaged in nightlife activities. Or metaphorically describing intense passion for life or dreams of youth never fading.
