How it's used
Focuses on a decline in performance or skill level compared to a previous state. It is frequently used in academic or professional contexts to highlight that someone is not keeping pace with their own past achievements or the standards of others. Unlike simply being bad at something, it implies a negative change from a higher level.
Examples
Have you regressed recently?
His Chinese grades have regressed significantly.

Common phrases

obvious regression
Common mistake
Avoid using it to describe physical movement backward, as that is better expressed by 後退. It is strictly for abstract concepts like ability, grades, or quality.
