Philosophical and Religious Roots: In Daoism and Buddhism, the universe is often divided into different realms. 凡人 are the inhabitants of the mortal realm (凡间 fánjiān), living lives of struggle, desire, and eventual death. They are distinct from 仙人 (xiānrén), the deathless immortals who have transcended these worldly constraints. This dichotomy is central to countless myths, legends, and religious teachings that explore the path from the mortal to the divine.
The “Muggle” of Chinese Fantasy: For a modern Western comparison, 凡人 functions very much like the term “Muggle” in the Harry Potter series. It describes someone without special powers or knowledge, living a normal life, completely unaware of the larger, more magical world operating alongside them. In the popular Chinese fantasy genres of Xianxia (仙侠, “Immortal Heroes”) and Wuxia (武侠, “Martial Heroes”), the story almost invariably begins with a 凡人 protagonist who, through luck, tragedy, or sheer willpower, embarks on a journey of “cultivation” (修仙 xiūxiān) to become powerful, or even immortal. The appeal of these stories lies in the ultimate underdog fantasy: the journey of an ordinary mortal to godhood. The famous novel and animation series “A Record of a Mortal's Journey to Immortality” is titled 《凡人修仙传》.
A Statement of Humility: Culturally, there is value placed on humility. Referring to oneself as a 凡人 is a way to manage expectations and acknowledge one's own limitations. It's a statement that one is subject to the same flaws, emotions, and frailties as everyone else, in contrast to a sage or a hero.
