(Korean: “long life”), wooden or stone pole carved with a human face and placed at the entrance (and sometimes to the north, south, east, and west) of a Korean village or temple to frighten away evil spirits. Among rice-growing peasants, it is believed to be a guardian (guardian spirit) deity who can dispel evil and cure disease. It may also serve as a signpost showing distances or indicating boundaries.

The typical changsŭng is about 2 m (6 feet) tall, with a red face in which eyes and teeth are prominent. The face may be male or female, and changsŭng are sometimes set in pairs. A male head wears a crown and surmounts an inscription reading “Great General over the Land” (Ch'ŏnhataejangkun); beneath a female face appears the title “Female General Under the Earth” (Chihayŏjangkun).

Similar to the changsŭng in spiritual significance, the somewhat taller sotdae, usually surmounted by a carved crane or duck, may also be erected before a tomb or a house to commemorate the holder of a civil-service position during the Chosŏn (Yi) dynasty (1392–1910).
