美国超人有裤衩中国悟空有短裙
[mĕi guó chāo rén yŏu kù chà zhōng guó wù kōng yŏu duăn qún]
Translated loosely as 'Superman wears underpants whereas Sun Wukong wears shorts', it reflects on cultural differences between superheroes from the East and West in terms of attire. The user is making a lighthearted comparison of costumes from popular culture heroes in China and America, indicating that even iconic figures like these have distinct regional characteristics.
