Abstract: Affected by the new crown pneumonia epidemic,colleges and universities adopt a closed management model of "no entry unless necessary",strictly control risk points,ensure campus safety and stability,and put forward new requirements for the work of college student party branches.A series of practical explorations in the closed-loop management of the temporary party branch of a college volunteer station for the Beijing Winter Olympics and Paralympics is a typical case of student party branch education during the period of closed management of colleges and universities under the background of the epidemic.It plays an important role in maintaining campus harmony and stability.Serving students' growth and becoming talents,and solidly carrying out ideological construction have provided valuable experience on key issues.
