Originating from natural science, Complex Dynamic Systems theory was brought into metaphor research by Cameron, leading to new trend in analyzing metaphor in discourse. Systematic metaphor, with a topic focus, spans across several discourse events and expresses relevant semantic meanings. It has been applied to investigate the semantic systemacity of contextual metaphors and is also the theoretical basis of this study. It was found that the diversity of systematic metaphor in terms of semantic types, mapping, and interactive relations facilitates the interpretation of metaphor use. This will also enhance a contextual, dynamic, interactive, and introspective analytical perspective.
