用法说明	Use 'once' to refer to something happening a single time in the past. It's neutral and often used in storytelling. It wouldn't be appropriate in highly formal writing.	Use 'simultaneously' to describe two or more actions happening at the same time. It works well in both spoken and written contexts but may sound overly formal in casual conversation.
