没有公主命就要有女王心
[méi yŏu gōng zhŭ mìng jiù yào yŏu nǚ wáng xīn]
The literal meaning is 'if you do not have the life of a princess then you should have the mentality of a queen.' Encourages people born in ordinary conditions to still maintain dignity, pride, independence, and confidence, not giving in due to lack of privilege
