薄荷不及你凉柠檬不及你酸
[bó hé bù jí nĭ liáng níng méng bù jí nĭ suān]
In a literal sense, it means 'mint is not as cool as you; lemon is not as sour as you.' Metaphorically, it implies comparing someone's effect on oneself as cooling (indifferent) or souring (upsetting or making sad) feelings more powerfully than any ordinary comparison.
