刘哥哥你是我的夫白九妹你是我的妻
[liú gē gē nĭ shì wŏ de fū bái jiŭ mèi nĭ shì wŏ de qī]
Roughly translates as 'Brother Liu is my husband; Sister Bai Jiu (a name referring to someone with white skin or being the 9th daughter) is my wife', which reflects a humorous and nonsensical statement playing on the idea of sibling relationships and roles within a family.
