Most of current research seems to proceed from a homogeneous conception of the Chinese ethnic minority in North America and Europe. The present paper focuses on ethnic Chinese migrant children living in Northern Ireland whose parents come from Mainland China and Hong Kong, respectively, and examines their intra-ethnic and inter-generational experiences based on in-depth interviews and participant observations. The purpose is to identify and explain both historical dynamics and intra-ethnic diversities within these Chinese children's accounts. The research employs culturally grounded versions of explanations, argumentations, narratives, `habitus', etc. as analytical tools. The research discovers the changes in and differences between these two Chinese sub-groups in views and values on self-concept, norms, country of origin, host society and life-style choices.
