This study adopted a social-ecological model as a framework to provide a more complete description of Yucheng in order to understand its effects on affected individuals, communities, and society. At first, recent studies on Yucheng victim's health effects  was updated. Long-term follow-up studies of Yucheng cohort have revealed the adverse health effects exerted on victims and their children. Subsequently, this study uses the disaster ecology model as a conceptual framework to review Yucheng. The movements of Yucheng victims and their supporters have constituted a primary actor for promoting the personal and legal rights of Yucheng victims. Finally, this study discusses how to improve future studies to effectively assist victims in their recovery from this incident.
