With the implementation of the national "urbanization" strategy, the citizenization of migrant workers has become an important part of China's urbanization process. The citizenization of migrant workers not only relies on the institutional reform to promote the exogenous citizenization, but also depends on the dissemination and cultivation of core socialism values, and it transforms traditional migrant workers into real urban citizens. Therefore, it is particularly urgent to strengthen the dissemination of core socialist values to the migrant workers, and it is necessary to systematically optimize the four elements of dissemination subject, dissemination object, dissemination medium and dissemination environment.
