The significance of such relevance lies in that the literature and art has gone through two stages of development, or two types. One type of art is influenced by both the classical realistic art of the Western Europe and the socialist realism of the former Soviet Union. Though the historical and realistic themes covered by such type of art are revolutionary and highly consistent with the ideology of the ruling Communist Party of China, the artistic language and style are stamped with the academism features, which was represented in the fine arts seventeen years before the Cultural Revolution.
这种相关的重要性在于:在毛泽东时代,文学艺术经历了两个发展阶段,或者说两种类型,一种是受西欧的古典写实艺术和前苏联的社会主义现实主义影响的艺术,尽管这种艺术表达的历史和现实的题材是革命的,与执政后的中国共产党的意识形态高度一致,但在艺术语言和风格上,却具有较强的学院特征。
