儿子看好爹给你摇个娘姑娘看好娘给你变个爹
[ér zi kàn hăo diē jĭ nĭ yáo gè niáng gū niáng kàn hăo niáng jĭ nĭ biàn gè diē]
This quirky phrase humorously describes roles reversal within family dynamics; it implies 'let your son grow up to become someone like me, while my daughter will grow up being just like you' in a comical sense.
