What major does graphology belong to?

At present, there is no formal definition in China, and it is a marginal discipline. Graphology does not belong to calligraphy or psychology, because the tasks are different. Graphology is the study of handwriting, and it is the study of traces of writing. It can be used to analyze personality and psychology, and it can also be used to identify whether it is the same writing. Graphology is the study of handwriting, not just psychology. So it is not accurate to say that it is psychology.
