星期八嫁你好吗
[xīng qī bā jià nĭ hăo ma]
Can I Marry You On Sunday (the Eighth Day)? : Playfully refers to marrying the other person on a made-up day of the week—Saturday is traditionally 7th day in Chinese counting, hence humorously adding a non-existent day suggests a playful or dreamy notion beyond reality.
