Core Viewpoint - The rise of the "doomsday rebirth" genre on platforms like Douyin reflects contemporary societal anxieties and desires, serving as a form of escapism for individuals facing uncertainty in 2025 [1][3][20]. Group 1: Characteristics of the "Doomsday Rebirth" Genre - The genre emphasizes survival over complexity, focusing on the simple notion of "staying alive" rather than exploring moral dilemmas or human nature [5][22]. - Unlike traditional Western doomsday narratives that highlight protagonists' combat skills, the Douyin version prioritizes luck, intelligence, and supernatural abilities, featuring ordinary individuals who gain foresight about impending disasters [9][10]. - The narrative often includes practical survival strategies, such as exploiting financial systems to gather resources before the apocalypse [10][12].
