妲己再美终是妖纣王再丑终是王
[dá jĭ zài mĕi zhōng shì yāo zhòu wáng zài chŏu zhōng shì wáng]
'Even if Daji is as beautiful as an enchantress she's still regarded as monster whereas King Zhou even ugly still reigns supreme as a king'. Here 'Daji' and 'Zhou Wang' come from classic legends of ancient China, implying one should see beyond appearances and not to judge only by what you see.
