Definition

In the past; previously; formerly.

colloquialtime

How it's used

Carries a nostalgic or reflective tone that feels more grounded and less formal than the standard written term 過去. It is primarily used by older generations to describe states or habits that have since changed. While perfectly understandable to younger speakers, it is rarely part of their active vocabulary.

Examples

This place used to be a piece of wasteland.
Did you live in Sham Shui Po in the past?

Common phrases

back in those days

Common mistake

Do not confuse this with 舊時, which is more commonly used in modern speech to refer to the 'old days' or 'former times'. Using 舊底 in casual conversation might make you sound like you are mimicking an older relative or speaking in a slightly dated style.
