洋葱的爱青葱的菜
[yáng cōng de ài qīng cōng de cài]
Using onion and scallions metaphorically, where 'onion love' suggests layers that could mean a multi-faceted form of affection and green onions implying freshness. A poetic way to say that relationships can be complex, tear-inducing and refreshing like cooking ingredients.
