This book is mainly divided into two parts: the study of fuzzy linguistics and the study of rhetoric. The content of this book mainly consists of the papers I have published from my early research to recent years (2012-2023) related to fuzzy linguistics and rhetoric. The research on fuzzy linguistics includes the study of the concept of fuzziness and fuzzy language, while the study of rhetoric can be further divided into two major parts: the study of poetic rhetoric and the study of Buddhist parables.
