"Chinese" is an ambiguous term, depending on whether it is taken to describe a political, linguistic, or cultural entity. While the term has often been considered to represent a politically and culturally homogeneous national identity in recent decades, this article aims to challenge this notion by examining the characteristics and practices of nationalistic education in Hong Kong since 1945. It explores how national identity has been interpreted by different Chinese states over time through different educational policies and practices. Focusing on the evolution of nationalistic education in three phases, this article presents a detailed account and analyses different nationalist narratives over six decades. It describes how different political forces define themselves and come to terms with what are often dual or competing national identities. Historical examples illustrate the challenges in policies and practices of nationalistic education.
