风华不过一指流砂苍老也是一段年华
[fēng huá bù guò yī zhĭ liú shā cāng lăo yĕ shì yī duàn nián huá]
Translated as 'Elegance flows through fleeting sand grains; aging too is an era of time,' this suggests that youth fades quickly like sand slipping through fingers, while aging itself signifies a period in one's life that has its significance.
