庭帷落花依争艳旧人旧事早已更
[tíng wéi luò huā yī zhēng yàn jiù rén jiù shì zăo yĭ gèng]
'The fallen flowers under the courtyard canopy still vie for brilliance, but old people and past events have long since changed' evokes the theme of impermanence in life: things around may seem the same or even thriving, yet people and events from the past have already faded away.
