Stimulated by the times, they opposed Wang Xue's empty talk about mind and nature in the late Ming Dynasty and put forward the idea of "combining Confucian classics without promoting Neo-Confucianism" in an attempt to awaken people's hearts and revive the nation through Confucian classics and history. Gu advocated that "everything is not based on the Six Classics, and everything is not people-oriented" (Book with People). Huang Zongxi said: "The beauty and evil of literature are divorced from reality." This began to change the style of study in the late Ming Dynasty. Later, Yan Requ, Hu Weiwei and others raised the banner of Sinology and attacked Song Studies. These have had a far-reaching impact on the style of study in the Qing Dynasty, and also played an important role in the literary theory and creation in the Qing Dynasty. The retro tendency in poetry and even novels and operas in the Qing Dynasty is related to this style of study.
