The rhythm and distribution of the audience's attention is the basis of the story structure. The story structure is a kind of design for the audience's attention.

The integrity of the story structure is the artist's promise and fulfillment of the audience's attention.

The English writer Sidney of the Renaissance mentioned in his famous treatise "A Defence of Poetry" that the king of Troy sent his young son and a large treasure to King Celes because of the war. A few years later, the king of Troy died, and King Seles killed the child in order to covet the great treasure. As it happened, the child's mother found her son's body, and she quickly took revenge with a stratagem. Obviously, Sidney's story is the subject of a tragedy by Euripides. Sidney said, "Where would one of our tragic writers start writing this play? It starts with sending children. So he sailed across the sea into Seles, and so on for an unknown number of years, and went for an unknown number of places. But where did Euripides start? It all started with the discovery of the body. "Euripides takes a tight, dramatic structure. Euripides tries to focus the viewer's attention on the most interesting episodes, and in this story, the child's mother avenges her son is clearly the best passage. The long prehistory, since it is not enough to attract the audience, let them be explained as a recount.

Attention to the substance or direction contained also prescribes different ways in which the play is structured. Psychology believes that attention is not a purely independent mental process, but contains mental activities such as perception, emotion, and understanding, or in other words, it is a common feature of these mental activities. Therefore, when attention is focused on different mental activities, the way in which it is structured will vary accordingly. The requirement that drama uniformly implement a certain "optimal" structure is completely contrary to the richness of people's mental processes.

The relationship between the audience's attention and the story structure determines that the screenwriters and directors of all mature dramas, movies, and TV series must be masters of storytelling. Their ability to tell a story is the foundation for coherence with other artistic abilities. With narrative ability, other abilities can be activated; lacks narrative ability, and other abilities can't be raised, becoming a loose bead and broken jade without stringing. Narrative ability is the ability to tell a story, that is, the ability to create a plot and structure based on predictions of the audience's attention. Without this psychological basis, it is impossible to truly understand the origin of the story, plot, and structure of a work of art.

In Poetics, Aristotle puts the importance of plot and structure ahead of many artistic factors. But to this day, the most lacking artistic ability of Chinese artists is the ability to tell stories.
