据说数学不好的女生都很美
[jù shuō shù xué bù hăo de nǚ shēng dōu hĕn mĕi]
Translated as 'Girls who are poor at mathematics tend to be beautiful,' this is based on a common but nonscientific stereotype suggesting those who aren't naturally gifted in mathematics may compensate by being especially pretty. It highlights an amusing contrast between perceived intellectual ability and physical attractiveness according to cultural bias.
