Abstract: Microblog,as one of the most famous new media, has become more and more popular among postgraduates. But most of the universities nowadays haven’t realized the positive influence of microblog in the ideological and political education of postgraduates. The traditional ideological and political education system used is outdated and unable to meet the needs of current postgraduates. In order to make good use of microblog, we provide corresponding solutions as to expand the moral education online, to create friendly network environment and to build up a high-level online ideological and political educational team according to the characteristics of postgraduates using microblogs and the current situation of ideological and political education of postgraduates.
