没公主命就得有公主心
[méi gōng zhŭ mìng jiù dé yŏu gōng zhŭ xīn]
Meaning 'If not born with a princess’s fate, one must have a princess's heart'. It conveys the idea that even if someone does not come from royalty or luxury, they can still carry grace and pride within themselves. A call for dignity amidst hardship.
