Bundling in the fan circle means that when the peripherals are transferred, all PB, cards, signatures, stickers and other peripherals are packed together and taken away. Fan circle, the abbreviation of fan circle in Internet terms, is mostly organized by celebrity management companies to lock in the fans of their stars. As the fan base expands, the idol economy continues to develop, giving rise to various methods such as buying peripherals (derivative products) for idols, renting advertising space for publicity, voting, and conducting charity activities. As of now, the fan circle, an entertainment community formed spontaneously by star-chasing fans, has gradually developed into an organized and professional interest circle.
