The COVID-19 pandemic has led to a sharp deterioration of Chinese international students' social and psychological environment. Social isolation, public media opinion, school blockades, and social unrest have brought huge psychological impacts to Chinese students. Moreover, the education sector has unaddressed the difficulties and worries faced by Chinese students considering learning overseas during the pandemic. Chinese students are prone to homesickness and loneliness since they spend much time alone living and studying abroad in a completely foreign cultural setting. In addition, in the context of COVID-19. In the psychological response, many international students follow the social isolation policy, take classes at home, and reduce travel. Physical isolation and reduction of social interaction aggravate psychological loneliness. Against this background, from the viewpoint of actor networks, this study investigates the network of issues and challenges encountered by Chinese students who desire to go abroad for academic learning. The findings suggest that Chinese international students have heightened psychological anxiety during Covid-19 and are worried about their future development. Therefore, future research should combine large-scale questionnaire surveys, detailed behavioral experiments, in-depth case analysis, and effective online intervention to explore theoretical models and intervention plans for overseas students' mental health to improve Chinese students' mental health: cultural adaptation and stress resilience of groups.
