Origins
Multiple Origin Theories
Several theories concern the origin of the Zhen surname: one connects it with the occupation of divination, another traces it to one of Baekje's eight major surnames, and another holds that it developed after an original surname was omitted from a personal name. A theory of surname concealment or change also exists, but has not been confirmed.

Research Notes
“Zhen Ji” Was Not an Original Surname
The “Zhen Ji” mentioned in Biographies of Exemplary Women was a title bestowed by the King of Wu on a Chu woman praised for her chastity and righteousness, rather than her original surname.
