Mainland China and Taiwan have a homogenous macroculture, but a heterogenous microculture. To understand the acculturation of students from mainland China to Taiwan, the present study applies Berry's (1997) two-dimensional model of acculturation, together with the concept of cultural types as its analytical framework, using focus group interviews to analyze different directions of acculturation among students from mainland China in Taiwan. The results show that regarding personal values, due to Taiwan's restrictions on students from mainland China and the fact that they must eventually return to their place of origin, the acculturation of students from mainland China mainly takes the "separation/segregation" mode. Regarding peer selection, due to differences between individuals in their interpersonal choices, they may adopt "separation/segregation" or "integration" modes. Regarding the period of residence in Taiwan, as students from mainland China spend longer in Taiwan, they tend more towards "integration." However, when teachers show greater contempt for the culture of mainland China, the acculturation of students from mainland China tends toward the "separation/segregation" mode.
