装淑女的个个都是老女人
[zhuāng shū nǚ de gè gè dōu shì lăo nǚ rén]
The username suggests that everyone who pretends to act ladylike appears as an old woman, indicating cynicism about those who affect artificial behaviors to give off a good impression. Be cautious: the phrase holds some disrespectful and stereotypical prejudice.
