儿子立正跟爹混女儿稍息跟娘走
[ér zi lì zhèng gēn diē hùn nǚ ér shāo xī gēn niáng zŏu]
This nickname reflects a traditional family hierarchy and relationship in a humorous way. In this context, '立正' (stand at attention) signifies following the father's orders or path while '稍息' (at ease) means following the mother more loosely or comfortably.
