How it's used
This idiom is a formal expression often used in professional or serious contexts to explain why someone cannot intervene in a situation. It implies a physical or jurisdictional distance that makes assistance impossible, rather than a lack of willingness to help. While it is a four-character idiom, it is frequently integrated into spoken Cantonese sentences with particles like 呀 or 㗎 to soften the tone.
Examples
I want to help you, but it's really beyond my reach.
So much is happening over there, how can we possibly be unable to reach them?

Common mistake
Learners often mistake this for a general term for being busy or lazy. It specifically requires a sense of distance or external constraint that prevents action, not just a personal lack of time or resources.
