Oeyeondo Dangje is a traditional ritual held on the isolated island of the west coast, which is held on February 15 of the lunar calendar every year.

Oeyeon-do Dangje can be seen as a typical example of folk beliefs on the coast of South Chungcheong Province, including a number of symbolic elements of traditional culture, and various sacrificial rites such as Dangje, Pung-eohje, and Jeonhaeng General's Sadangje are held, including ritual procedures and pungmul sounds with unique characteristics of the island area. These rituals are more popular because they have procedures for offering non-stated offerings, including tribute, cultivation, and shamanistic tales, without the introduction of Confucian texts.

The rite was held three times a year before the 1970s, but was later reduced to Jeongwolje Shrine in 1987 due to the voluntary will of the residents, but the ritual was held in accordance with the tradition.

With such diverse intangible cultural heritage elements, Oeyeon-do is an important religious material that represents the island area of South Chungcheong Province and shows the differentiation of mountain gods and human gods amid changes in religious needs in terms of Korean folk beliefs, so 이므로span class='onmouseover='onmouseover='up2 (2060)' is onmouse.
