孩纸玩心不累吗
[hái zhĭ wán xīn bù lĕi ma]
This translates to 'Child Paper, Isn't Your Heart Playing Too Much?'. This might be poking fun at immature behavior, particularly related to relationships or emotions. 'Paper Child' could be referring to being thin-skinned or too sensitive. It could also suggest a playful critique toward people's excessive carefreeness and lack of responsibility when it comes to serious matters like love and relationships.
