Expressing "all at once" with "yixiazi"
一下子 (yīxiàzi) can be used as an adverb, meaning "all at once." Because it inherently encompasses a sense of "completion," it's typically going to be followed by a 了 (le) later in the sentence.

Used as "All at Once"
一下子 (yīxiàzi) is a very informal expression to describe how fast things happened. It usually touches upon sudden or severe changes in a very short amount of time. Although 一下子 (yīxiàzi) is already quite informal, in colloquial Chinese 一下 (yīxià) can also be used to express the same thing.
Structure
Subj. + 一下子 + Predicate + 了
Examples
- 天气 一下子 变 冷 了 。The weather suddenly got cold.
- 他 一下子 吃 了 三 碗 米饭 。He ate three bowls of rice all at once.
- 她 下楼 的时候 一下子 摔倒 了 。As she went down the stairs, she suddenly fell.

Used as "Quickly" and "Naturally"
一下子 (yīxiàzi), followed with 就 (jiù), usually implies that things happened very quickly, naturally, and easily. Again, 一下 (yīxià) can also be used instead of 一下子 (yīxiàzi).
Structure
Subj. + 一下子 + 就 + Predicate + 了
