If the person and the subject were consistent, it would make it easier for the readers to understand and resonate with the article, enhancing the legibility and emotional expression of the article. For example, the use of " he " and " she " could make the article more intimate and trustworthy, and at the same time, make it easier for readers to resonate with emotions. In addition, using the same person and subject can also make the article more coherent and consistent, making the story more smooth and natural.
