白九妹你是我的妻啊哈哈刘哥哥你是我的夫啊哈哈
[bái jiŭ mèi nĭ shì wŏ de qī a hā hā liú gē gē nĭ shì wŏ de fū a hā hā]
In translation, it says 'white-nine-meidi(usually means younger sister in Mandarin), you are my wife haha Liu-gege (literally elder brother) you are my husband haha'. Perhaps it refers to someone from the movie or novel, and it also reflects a humorous attitude with playful use of familial titles.
