你姓刘而我却留不住
[nĭ xìng liú ér wŏ què liú bù zhù]
'You surname Liu, but I just can't hold you back,' which could be a phrase with personal meanings between the narrator and the target, possibly pointing out that though one has tried hard, he or she still can not prevent the other from leaving. 'Liu' might either just be used as a name or may sometimes refer to staying in Chinese (留下).
