当年容嬷嬷也是当了校花的
[dāng nián róng mā mā yĕ shì dāng le xiào huā de]
“容嬷嬷” refers to a strict and sometimes cruel nanny character from a classic Chinese historical drama, and “校花” means 'school beauty.' This playful name imagines a sharp contrast between severe appearances and an unexpectedly beautiful past or hidden talents or personality. It can suggest that one might have unexpected qualities under stern exterior.
