Mid-length novels usually referred to novels with a narrative length of more than one million words or even more than two million words. A mid-length novel usually had a complicated plot, rich characters, a broad background, and a profound theme. The creation of a novel required sufficient time and energy, and the author must have a high literary quality and creative ability. At the same time, the novel also needed to have enough depth and breadth to fully express the theme and meaning of the novel. Medium-length novels generally needed to go through repeated conception, revision, and creation to complete a good work. In the process of writing, the author should pay attention to the details, plot and character image so that readers can better understand and feel the theme and meaning of the novel. In short, novels are an important part of literature, with unique charm and artistic value.
