(Chinese: “realized man”), in Taoism, a god or deified mortal; the term has been the official title of the head of the Cheng-i Taoist sect since the late 13th century.

The Taoist sage Chuang-tzu (Zhuangzi) used the term chen-jen, along with shen-jen (“spiritualized man”), chih-jen (“perfected man”), and sheng-jen (“sage”), to refer to the Taoist ideal man who had achieved immortality and was immune to earthly desires and dangers. The term hsien (“immortal”) was used by other philosophers somewhat synonymously.
