肥皂泡中蹉跎了岁月
[féi zào pào zhōng cuō tuó le suì yuè]
Translating to 'Wasting Time in Soap Bubbles,' this implies living a life filled with empty promises or fleeting moments of joy which eventually disappear, much like how soap bubbles burst quickly. It reflects a sense of nostalgia and regret for lost time.
