学习不好的姑娘都很漂亮
[xué xí bù hăo de gū niáng dōu hĕn piāo liàng]
'Girls who don't do well in studies are very beautiful'. This carries a societal observation and subjective judgment implying physical attractiveness does not necessarily relate to academic performance, but it also contains a hint of irony or criticism against superficial stereotypes.
