没有公主命但要有女王心
[méi yŏu gōng zhŭ mìng dàn yào yŏu nǚ wáng xīn]
One may not live a privileged life like a princess (with lots of ease and support), but should have high self-esteem and strong will like that of a queen. Roughly translates to 'without a princess's destiny but must possess a queen's mindset'
