一切都是过眼云烟一切都是昙花一现
[yī qiè dōu shì guò yăn yún yān yī qiè dōu shì tán huā yī xiàn]
'All things are like a passing cloud; everything is ephemeral as the night-flowering cereus'. This conveys an idea that all worldly matters and glories don't last forever, showing a philosophy of regarding wealth and status as trivial.
