With the rapid development of Teaching Chinese as a Foreign Language (TCFL), improving teaching quality requires integrating advanced pedagogical concepts. Multimodal teaching, which employs various symbolic modes to engage students’ multiple senses, is a highly effective approach. Introducing multimodal theory into TCFL education can enhance teaching efficiency and improve students’ communication skills. This paper applies multimodal theory to TCFL, using the elementary Chinese comprehensive course “My Family” as a case study to propose a detailed teaching design, followed by evaluation and reflection. The aim of this teaching design is to deepen the understanding of multimodal theory and provide additional reference for the TCFL.
