鉛筆畫再美終是灰色旳
[qiān bĭ huà zài mĕi zhōng shì huī sè dì]
Literally translated as 'No matter how beautiful the pencil drawing is, it ends up gray.' This phrase expresses melancholy over something temporary or transient yet aesthetically pleasing (like a pencil sketch). In life context, this might reflect upon brief pleasures or dreams that cannot come true and will fade eventually despite looking appealing at present.
