Using Deleuze and Guattari's concept of rhizome, this study examines the key measures of the Kindergarten Education Scheme introduced by the Hong Kong government in 2017 after a large‐scale advocacy movement. It argues that these measures have expanded the power of the neoliberal imaginary through producing an enhanced market apparatus and an apolitical teaching profession. The neoliberal expansion reflects the manifestation of different kinds of rhizomatic connections to reterritorialise the field. This study calls for the rethinking of teacher educators’ ethical responsibility in addressing the complexity of teacher work frequently neglected by policy and the policy/practice divide in teacher education.
