穿水晶的不一定是公主骑白马的不一定是王子
[chuān shuĭ jīng de bù yī dìng shì gōng zhŭ qí bái mă de bù yī dìng shì wáng zi]
Translates to 'Wearing crystal doesn’t make you a princess; riding a white horse doesn’t make you a prince.' It cautions against judging people based on appearances or material possessions. True value and worth lie deeper than surface-level traits.
