从“双线文学”理论出发，五四先驱的文学革新主张已受到了古代“基层”通俗小说的成功经验的启迪。古代通俗小说首先以“言文合一”的语体特色，为五四先驱提供了作家应该“怎么写”的有益借鉴。其次是推动五四文坛树立了以小说为文学正宗之一的新观念，从而使小说成了改良人生的利器。最后在创作的思想寄托等问题上，也给了五四先驱以作家应该“写什么”的积极影响。 Proceeding from the theory of “two lines of literature,” the pioneer of literature in the May Fourth Movement has been inspired by the successful experience of ancient “grassroots” popular novels. The ancient popular novels first provided the writer with the “how to write” useful reference for the May 4th Pioneers through the stylistic features of “unity of speech and text.” Second is to promote the May Fourth literary world to establish a novel as one of the literary authenticity of the new concept, so that the novel has become a tool to improve life. Finally, on the issues such as the pinning of the creative thoughts, it also gave the positive influence of May Fourth pioneers on what the writers should “write.”
