Introduction: sound bites won't work: case studies of 15-year free education in Greater China

This special issue collects six interesting case studies on the so-called 15-year free education in four Chinese societies including Hong Kong, Macau, Mainland China, and Taiwan. The selected works analyze the target education policies based on the theoretical framework of 3A2S - affordability, accessibility, accountability, sustainability, and social justice. Together, they provide a multifaceted account of the merits and limitations of the 15-year free education policies implemented in Greater China. The authors examine the education policies in their respective socioeconomic contexts and aim to suggest new research agenda for early childhood education in these Greater Chinese societies.
