Second person perspective: Compared to the first person perspective, the readers have a deeper understanding of the plot and characters of the story, but they may feel more constrained and lack a sense of direct participation. The second person could also better express the author's emotions and thoughts, increasing the literary appeal and depth of thinking. Third-person perspective: Able to present the story more objectively and reduce the emotional interference of the reader, making the story more calm and objective.
