This article uses the theory of "critical geopolitics" or "postmodern geopolitics" to analyze the official movies of "Me and My Motherland," which was released on China's National Day. The purpose is to explore how the film constitutes a geopolitical storyline, and how it forms a cognitive map of Mainland China in the popular imagination and forms a specific geopolitical imagining, which further demonstrates a national identity. Without anyone as the film's main character, the study found that the film's storyline is closer to the popular imagination and national identity. Furthermore, it tallies with the geopolitical storyline of Xi Jinping's "Chinese Dream".
