铅笔画不出薄荷
[qiān bĭ huà bù chū bó hé]
'The Pencil Cannot Draw Mint' signifies the impossibility of depicting certain sensory experiences (like taste or smell), specifically something as distinct as mint. The metaphor here suggests something that can't be captured through ordinary means—there are elements of life which go beyond our tools, indicating there are aspects of beauty or experience beyond tangible reach.
