The monogatari and monogatari novels are both genre of Japanese novels. The main difference lies in the literary form and theme. Monogatari was a form of expression for the literary genre of "monogatari". Monogatari was a narrative method in ancient Japanese legends that emphasized the environment in which the story took place and the emotional experience of the characters. It used nature, monsters, history, legends, and other main topics, often using symbolism and mysticism to convey the author's thoughts and emotions with unique artistic expression. The masterpieces of the monogatari genre included The Tale of Genji and The Story of the Purple Hairpin. The novel of Wu Ai emphasized lamenting and sympathizing with the fate of the characters, focusing on describing the inner world and living conditions of the characters. The main theme was the life and fate of ordinary people, often using realism and tragicism to reveal the dark side of society and life, expressing the pain, loneliness, helplessness and despair of the characters. The representative works of the mourning style include The Four Great Continents and The Peony Pavilion. The monogatari novel and the monogatari novel are both important representatives of the Japanese novel genre. They are different in literary form and theme, but they both focus on expressing the emotions and inner world of the characters, revealing the value and meaning of society and life.
