In the wave of globalization, the trend of internationalization and globalization of higher education has become more and more obvious, and the study abroad experience of college graduates has become an important driving force for their personal development. Returnees from colleges and universities are an important link between China and the international community, and the increasing number of returnees from colleges and universities also signifies the strengthening of the national image and cultural soft power. China’s policy of supporting college and university students to study abroad has provided convenient conditions for students with academic pursuits. During the period of studying abroad, the group's needs for improving their disciplinary literacy and technical ability have been greatly satisfied, but in the face of the complex foreign environment, it is also particularly important to effectively guide the ideological and political education work of college returnees. Combined with the wave of digitization, it is imperative to use new media to strengthen the ideological education of returned overseas students in colleges and universities and improve their ideological and political literacy.
