没有小怪兽的凹凸曼没有凹凸曼的小怪兽
[méi yŏu xiăo guài shòu de āo tū màn méi yŏu āo tū màn de xiăo guài shòu]
This is a bit cryptic but references popular Chinese children's cartoons where AotuMan (a superhero) fights against monsters ('小怪兽'). The phrase suggests that they're meaningless without each other, akin to the yin-yang philosophy in Chinese culture which emphasizes mutual dependence between opposites.
