How it's used

Emphasizes the duration of an entire human lifespan, often used to express disbelief or to set a long-term expectation. It carries a stronger, more personal weight than just saying 成世. It frequently appears in negative constructions to highlight an extreme lack of experience or a long-standing habit.
