Abstract: The "circle layering" phenomenon in the online world, as a new trend of youth digital interaction, reflects profound underlying logic. It is characterized by self-organized circle formation, implicit authority-driven operation, symbolic and emotional discourse expression, and the coexistence of interwoven interaction and conflict. This phenomenon provides young people with emotional belonging and value orientation, while also fostering cognitive development, emotional resonance, and social participation. At the same time, it presents challenges for mainstream values in guiding youth, making value guidance within online "circle layering" increasingly complex. Addressing the significant influence of this phenomenon on the value formation of young people and actively exploring guidance strategies—namely "entering circles, breaking circles, integrating circles, and purifying circles"—is essential for improving the effectiveness of online ideological and political education and advancing the mission of moral cultivation. It also plays a vital role in mitigating online ideological risks and consolidating social value consensus.
