What novel tells the story of a god doctor who sells fruit and an old man who divines?

The novel is to be "said" in the "small". Judging from the development of novels, both in the east and the west, most novels in the traditional sense are mainly "talking", while modernist novels have begun to consciously move toward "small".

This "small" is the detail, the inner part, and the deeper place. Modern novels get rid of the commonness in many narratives and find unusual differences from small things.
