This Chinese-language volume offers a comprehensive introduction to graphology, the study of handwriting as a window into personality and mental processes. Drawing on both historical perspectives and contemporary research, the author examines the principles behind character analysis, the methodological tools used by practitioners, and the cultural contexts that shape interpretive frameworks. Readers are guided through practical techniques for evaluating stroke patterns, pressure, spacing, and other stylistic elements, while also considering the scientific debates surrounding the discipline’s validity. Illustrated examples and case studies illustrate how handwriting can reflect emotional states, cognitive habits, and even potential health indicators. Aimed at scholars, students, and enthusiasts of psychological inquiry, the book balances theoretical discussion with hands‑on guidance, making it a valuable reference for anyone interested in the intersection of psychology and written expression.
