The use of flashbacks at the beginning of an article was usually used to attract the attention of the readers and arouse their interest. Through flashbacks, readers could first understand the background, plot, and main characters of the story, so as to better understand the theme and content of the article. The expression of flashback can also make the structure of the article more compact and the layout of the article more reasonable. For example, when describing an unexpected event, using flashbacks could allow the reader to understand the occurrence and development of the event more quickly and better understand the main purpose of the article. It was important to note that when using flashbacks, the rhythm and suspense should be used reasonably so that the readers would not feel too depressed and boring.
