曾经的曾经兜是曾经现在的现在兜是现在
[céng jīng de céng jīng dōu shì céng jīng xiàn zài de xiàn zài dōu shì xiàn zài]
Translated as 'What was once is the past, what remains now is the present.' This phrase signifies the passage of time and change—how what seemed permanent before has changed with time, emphasizing on living in the present.
