Shamanist 'Changsung' poles
Changsung are usually a pair of wooden poles traditionally erected at the entrance of Korean villages, and their role is that of guardian deity of the villagers. Inscribed on the male poles are the Chinese ideographs, Ch'onha Taejanggun (great general under heaven), and their role is to protect all people passing on the roadways in and out of the village. The female Changsung is indicated by the five Chinese ideographs meaning "female general underground". She is the female deity who governs the conception and birth of children. Her vigilant care of children put villager parents at ease and this is why she was worshiped with attention, and still is in remote villages around the peninsula.
