Dear China: Emigrant Letters and Remittances, 1820-1980 is an economics work studying “qiaopi” (emigrant letters accompanied by a family remittance) and the origins, structure, features and operations of qiaopi trade. The author introduces how such institutionalized and cross-national mechanism helped sustain families separated by distance. Qiaopi, culturally valuable and worthy of study, has witnessed the emigration and entrepreneurship history of overseas Chinese as well as their contribution to the socio-economic development of the sending regions and the motherland. The excellent, detailed analysis and fact-based research make the book a benchmark for future qiaopi study.
