The outbreak of COVID-19 made the H Street day workers group and some Hubei labor workers become W temporary shelters. In order to make these people get rid of the emergency and return to the society as soon as possible，the local civil administration department introduced the professional service from social work talents to participate into the relief work of the resettlement site. Through participatory observation and qualitative analysis，this study finds that the causes of the plight of the recipients are sudden，multiple and complex. The service team has explored the servicing pattern of social work’s intervention into emergencies through triple paths，such as promoting the integration and utilization of resources through the construction of social support network，promoting the implementation of case management through dynamic regulation of practical objectives，and using social work’s professional quality to stimulate endogenous power. On this basis，this paper also analyzed the effectiveness and limitations of this service pattern.
