What is the reason for the change of Russian artistic concept?

Under the guidance of this concept, the artists of the "roving exhibition school" have created many excellent paintings that pursue the story and emphasize the social education function of art, but at the same time, it inevitably brings some disadvantages that art is attached to literature. At the beginning of the 20th century, around 1907, the limitation of literariness on painting art was abandoned, and artistic creation was required to return to the main body. The artistic concept of "pure painting" was quickly accepted by many Russian artists, especially young artists. The popularity of this new artistic concept is closely related to the artistic activities of "Blue Rose" society, the exhibition and publicity held by golden fleece magazine, and the introduction of French post-impressionist painting and fauvism painting.
