This text explores the evolution of China’s ACGN (Anime, Comic, Games, and Novel) culture from a niche hobby into a dominant mainstream economic force for Generation Z. The author highlights how cutting-edge technology, such as AI-generated imagery and motion synthesis, is being integrated into fan creative spaces. A central focus is placed on Bilibili, a platform that transitioned from an unofficial fan site to a major corporation by bridging the gap between user-generated content and copyright legality. By establishing systems like "Bilibili Huahuo," the platform allows creators to collaborate with major brands such as KFC, turning fan tributes into legitimate marketing tools. Ultimately, the source argues that the "otaku economy" has become an essential professional industry where technology and business interests align with youth subcultures.
