"This book fills [a] void by looking at Chinese diaspora in multiple geographic regions and countries ... with regard to the learning of the host language and English, as a lingua franca, while also learning and/or maintaining Chinese language and culture as a heritage language. … [It] gives readers an opportunity to compare and contrast the varied, data-driven studies and ethnographic accounts that represent the rich, yet complex intersection of sociocultural, multilinguistic and psycho-emotional perspectives." Jun Liu, Vice Provost for Global Affairs and Professor of Linguistics, Stony Brook University, USA, from the Foreword"This volume present[s] a great variety of contexts and different challenges, issues and experiences of different kinds of CHLs in different parts of the world…. [and] provide[s] us with some important pointers about what future work needs to be done." Angel M. Y. Lin, Professor of English Language and Literacy Education, University of Hong Kong, from the Afterword
