In this paper, I analyzed the gaps between strategic and actual mechanisms of colonial propaganda with a focus on changes in Manchuria representation. I analyzed the Manchurian pioneer narrative at the end of Japanese colonial period and the narrative of repatriation to Manchuria in the liberation period to trace variations between ‘power driving propaganda aimed at structural oppressive’ and ‘power driving substantive reality’. In the Son of Earth, a Manchurian pioneer narrative, an agricultural progressive narrative creates a new society through massive social engineering, a project combined with national government. In the text, modifications of nature and human beings are more distinguishable and highly manipulatable, with the focus moving increasing on productivity. Taken outright, according to the nationalist utopia discourse of the Son of Earth, the benefits of progress were all the results of social engineering, which excludes the Boy Grows Up, the Manchurian return narrative, from such official discourse. Boy Grows Up describes the live of a fragile boy who grows up in a way that provides him with the means to live on his own and with faculties of ethical discernment. In this way, the mutual assistance of ordinary people emerging as the core of the narrative allows us to identify desires for new subjectivities and communities discernable from ‘top-down progressive planning dynamics’. Thus, the Manchurian return narrative reveals gaps between the social engineering project and colonial realities, as well as gaps between the aims of pioneering narratives and diasporic reality by allowing for a postmodern colonial memories to probe inside colonial propaganda.
