This is the author's first attempt to use first-person subjective direct quotations to describe the inner activities of characters. It is a classic work of stream-of-consciousness novels. It is also a question on the so-called "objective authenticity". What the "spots on the wall" are is meaningless. What is really meaningful is people's subjective consciousness activities. He touched on the issue of the eternal continuation of life after the death of an individual, the opposition between nature and mechanical reality, the conflict between the spirit of literary innovation and outdated norms, and the issue of women's resistance to the male-centered system and male concepts.
