The exclusion and bullying targeting minority groups--including sexual minorities, individuals with disabilities, and orphans--have become observable social phenomena in Chinese campus settings. This review examines, from a social psychological perspective, how the herd effect operates within physical campus environments to trigger, amplify, and consolidate prejudice and discrimination held by majority groups toward minority students. Adopting a literature review methodology, this paper synthesizes Asch's conformity experiments, behaviorist theory, Freudian individual unconscious, Jungian collective unconscious, and empirical studies on school bullying and peer conformity published over the past two decades. The central argument proposes a "three-tiered ladder" through which the herd effect function: first, linguistic stigmatization transforms neutral identity labels such as "gay" and" Tang"(a colloquial abbreviation for Down Syndrome in Chinese, used similarly to offensive slurs like "mong" in English) into tools of humiliation; second, social isolation dismantles the victim's support network; and third, peer pressure escalates into physical violence and property damage. This mechanism is significantly amplified within the Chinese collectivist educational context, where the physical inseparability of fixed-class systems extends conformity pressure from temporary behavior into chronic survival anxiety.
