Consider using a style for citations. I imagine you're hoping for a left indent, and using a red box just to draw our attention to the examples?

Hi engine. Thanks for the reply. Sorry for my poor English. So I should use a style? how exactly am I supposed to do that? Is there like a template for it? Because 90% of the books and academic papers I've seen have the very same style, that's why I thought it must be an already-there option in the Word.
