Problem description:
Straight-line books often have a "right" at the beginning. I remember a teacher once said that the word "right" means that this paragraph should have been on the far right side of the page, but in order to save paper, connect it with other contents and mark it with a "right", which means starting a new page. Is that so? I can't remember clearly what the teacher said at the beginning. . . . )
Analysis:
Your teacher is wrong. "Right" is equivalent to "up" and "up" in today's popular layout (top-down). For example, "recording a poem by Lu Xun on the right" means "it's a poem by Lu Xun above". Because ancient books are written from right to left, when writing, it is called "right" when referring to the front (right) content, and it is often used when wrapping, so the word "right" often appears at the beginning of paragraphs in ancient books.
