How does Saul Bellow's creation reflect the combination of realism and modernism?

To put it simply, on the one hand, he pays attention to the deconstruction of modern life by modernist novels, so he consciously applies modernist creative skills such as stream of consciousness to the structure of novels; On the other hand, he fully absorbed the excellent tradition of realistic works in language and content, and paid attention to vivid and meticulous description in narrative writers, so the characters and small events depicted were vivid and vivid. That is, skill structure modernism and skeleton modernism; But the flesh and blood filled in this skeleton, every description, every event and every character in the structure are all completed by realistic means.
