灰姑娘也变王后青蛙也会变王子
[huī gū niáng yĕ biàn wáng hòu qīng wā yĕ huì biàn wáng zi]
Translates to ‘Cinderella turns into a queen, and the frog into a prince too’. It reflects fairy-tale optimism that people, regardless of their current circumstances or how others perceive them, can still become their best selves with time.
