柠檬不及我心酸薄荷不及我心凉
[níng méng bù jí wŏ xīn suān bó hé bù jí wŏ xīn liáng]
'Lemons are less sour than my heart, mint less chilling'. This metaphorical phrase depicts deep feelings of sorrow and coldness beyond simple comparison with lemons’ sour taste or mint’s cool effect. It portrays the depth of sadness within the person.
