The integration of non-local students into their host environments and their ability to develop meaningful local relationships are concerns for researchers, educators, and policymakers. Given the increased diversity of higher educational settings, a deeper understanding of these topics can help residential halls better accommodate students from various cultures, improve students' residential experiences, and enhance their relationships with their peers. Research on these issues has focused mainly on Western universities; this study aims to explore the acculturation dynamics of residential education through focus-group interviews with 14 Mainland Chinese undergraduates living in residential halls in Hong Kong. The findings reveal that although the residential experience can engender interpersonal conflict, it can also foster intercultural interaction, help build a sense of belonging, and create the conditions for overcoming barriers and difficulties. The findings indicate that future programmes can improve adjustment outcomes in residential halls by creating a more welcoming environment for non-local students.
