How it's used
This is a formal conjunction that is primarily used in written Cantonese or during structured presentations. In casual spoken conversation, native speakers almost always prefer using 仲有 or 同時 instead to keep the flow natural. Using it in everyday chat can make you sound like you are reading from a news report or a textbook.
Examples
He is eating, and at the same time he is watching TV.
The government needs to improve the economy, and at the same time pay attention to people's livelihoods.

Common mistake
Learners often overuse this in casual speech where it sounds overly stiff and unnatural. It is not a direct replacement for the simple conjunction 同 or the adverb 同時 when describing basic daily activities.
