女人你这辈子都是我的男人我这辈子都是你的
[nǚ rén nĭ zhè bèi zi dōu shì wŏ de nán rén wŏ zhè bèi zi dōu shì nĭ de]
This is a poetic yet somewhat confusing line that mixes traditional gender roles by playfully expressing devotion, meaning either gender is dedicated to the other exclusively, possibly highlighting unconventional love or companionship.
