Based on the demand for the "textbook integration" reform in Singapore's Chinese language education, this study focuses on the transition dilemmas between primary and secondary Chinese teaching. Through a four-year two-round progressive action research, it explores the role and sustainable development mechanism of cross-stage Teacher Professional Learning Communities. Targeting 28 Chinese teachers from 6 primary and 6 secondary schools in Singapore's S School Cluster, it adopts a mixed research method centred on action research, supplemented by questionnaires, interviews, and case studies, with practices centred on three teaching modules: Life Board/Life Space, Written Interaction, and Oral Interaction. The study finds that the PLC promotes the implementation of teaching integration through a "foundation-laying + in-depth optimization" model, fosters teachers' multi-dimensional professional development, and constructs a sustainable mechanism featuring "integration as the goal, a three-level echelon as the organization, diversified activities as the carrier, and culture, resources, and systems as the three-dimensional support". The research enriches the teacher professional development theory in the context of second language teaching and provides a replicable practical paradigm for the transition of Chinese language education between primary and secondary schools in Singapore.
