本宫不死尔等永是妃子
[bĕn gōng bù sĭ ĕr dĕng yŏng shì fēi zi]
The phrase translates to 'As Long As I Don't Die, You Will Always Be Consorts.' It refers to the ancient imperial system where a concubine (or 'feizi,' which translates loosely as consort) would stay in such status unless the emperor elevates or demotes them. The term has a tone of dominance and authority that harks back to traditional hierarchies.
