Short Interval with 不一会儿 in Chinese
不一会儿
不一会儿 means that only a short interval passes before an event occurs or finishes. It can frame the predicate inside a clause or connect a preceding situation to a prompt following event. 就 commonly reinforces the quick succession but is not mechanically required in every context. The phrase describes duration, not negation.

不一会儿 means that only a short interval passes before an event occurs or finishes. It can frame the predicate inside a clause or connect a preceding situation to a prompt following event. 就 commonly reinforces the quick succession but is not mechanically required in every context. The phrase describes duration, not negation. Keep the model 不一会儿 + (就) + Predicate / Clause，不一会儿 + Clause visible while you compare each sentence.
我不一会儿就做完了作业。
I finished the homework in a short while.
Choose the right context
Say that an event occurs after a brief wait. Describe completing an action in a short time. Link one situation to a quickly following event.
我们到了车站，不一会儿，车就来了。
We reached the stop, and before long the bus came.
Respect the boundary
Do not split the fixed phrase with another word. Do not interpret 不 as ordinary sentential negation. Do not place 就 after the completed predicate it modifies.
我不就一会儿做完了作业。
(I not then one while finished the homework.)
Repair the pattern
The fixed phrase is split: 不一会儿 is a fixed time phrase and cannot be split by 就. 就 trails the completed predicate: When used, 就 precedes the predicate that presents the promptly following event.
我不一会儿就做完了作业。
Use the repaired structure without changing the intended meaning.

08 / QUESTIONS
Short Interval with 不一会儿 Questions

No. The whole fixed phrase means before long or in a short while.
Must it always take 就?
No. 就 is frequent when emphasizing prompt succession, but punctuation and context also license uses without it.
