岁月已逝往昔容颜岁月不改往昔面貌
[suì yuè yĭ shì wăng xī róng yán suì yuè bù găi wăng xī miàn mào]
This translates to 'The Years Have Passed But The Appearance Remains the Same.' It implies how despite the passage of time and changing circumstances, the essence or memory of something precious remains intact and unaltered.
