During the Yan'an period, the educational function of the CCP’s press developed to a mature stage, which was particularly shown in the fact that the educational function was greatly enhanced vis-à-vis the propaganda and organizational functions and became an extremely important function. Hu Qiaomu’s Newspapers are Textbooks written in early 1943 provided a vivid historical grounding for this. This article explores the specific connotations, logical foundations, theoretical significance, and the relationship between the educational function and other press functions of the CCP during the Yan’an period.As an extension of the central metaphor “Newspapers as Textbooks”, the elements in the “education” domain and the “journalism” domain naturally formed a mapping relationship, constructing a conceptual framework around the educational function of the press, including the role and characteristics of the party newspaper and the responsibilities and ethics of newspaper workers.It provides a powerful interpretation for the redesign of party newspaper.Concepts such as “the party nature and people’s nature of newspapers,” “propaganda,” “organization,” “CCP characteristic journalism,” and “learning for education” constituted a network of meanings that help understand the connotations and positioning of the press's educational function, making it an important part of the CCP’s party press theory.
