红颜弹指老刹那芳华
[hóng yán dàn zhĭ lăo chà nèi fāng huá]
This phrase 'Beauty fades in an instant, splendor lasts only a moment' speaks of the fleeting beauty and youth, how rapidly time flows making attractive features diminish quickly. This reflects contemplation upon human appearance aging gracefully and understanding the brevity of youthful glory.
