我忘记你姓王叫忘不掉我忘记你姓刘叫留不住
[wŏ wàng jì nĭ xìng wáng jiào wàng bù diào wŏ wàng jì nĭ xìng liú jiào liú bù zhù]
'If I forget that you are surnamed Wang, it means I can never forget you; if I forget that you are surnamed Liu, it means I cannot hold onto you.' This implies the narrator's complicated sentiment of forgetting/remembering someone. In Chinese culture, homophones of surnames create playful meanings: 王 'Wang' sounds like 忘 ‘can't forget’; 刘 'Liu' resonates with 留 ‘to stay/hold’.
