Psychology comes from Greek, that is, psychology comes from Greek "soul" psychology and "thinking" logos, while the original Greek is soul: ψ υ χ? , research: λ? γ ο, so the psychological symbol is ψ.

The word psychology comes from Greek, which means the science of the soul. Soul also means qi or breathing in Greek, because ancient people thought that life depended on breathing, and when breathing stopped, life ended. With the development of science, the research object of psychology has changed from soul to mind.
