The “Complete Party Newspaper” is not only a key concept of the CCP’s publicity history, but also a discourse practice. Reviewing the concept by discourse analysis, we found that from the text aspect, “Complete Party Newspaper” was a mixture of Lenist party newspaper theory and local related ideological resources in China. From the perspective of discourse practice,the discourse of “Complete Party Newspaper” realized its own strengthening and reproduction by a series of intertextual discourses in the process of revision of Liberation Daily. From the perspective of social culture, the revision of Liberation Daily with the goal of "Complete Party Newspaper" was part of the Yan'an Rectifcation Movement. The revised party newspaper further promoted the development of the Yan'an Rectification Movement and finally established Mao Zedong's power of speech and cultural hegemony within the CCP.
