As the source of literature, of course, it is the life world. The world mainly refers to the social life or social reality reflected by literary activities. There is imitation theory in history;
The formal factor of literature is the text, because the text has a materialized appearance and a visualized result. Works mainly refer to the difference between the literary world and the real world, highlighting the difference between the literary world and the real world;
The factors of production are writers, because words are created by writers. The author mainly refers to literature, but also the author's performance activities. There are "poems expressing ambition" and romanticism in history;
