我爱你妈的儿子我爱你爸的女儿
[wŏ ài nĭ mā de ér zi wŏ ài nĭ bà de nǚ ér]
A somewhat humorous play on words expressing unconditional love for a partner's entire family—his mother’s son (him) and her father’s daughter (hers). It symbolizes a deep love that includes not just romantic partners but also embraces their families, reflecting familial bonds in Chinese culture.
