Before the Silla code of rites(祀典) maintenance period, it is possible that the Shamanism ritual held in the Chuam(湫巖) area would have undergone changes to become the open rates of the Confucianism North Sea Place of Worship(祭場). There were remnants of the uncommon sea god, The Dragon of the Sea(海龍神), who is the subject of the North Sea Coastal Rites, in the Chuam region, including sacred cows(神牛). This custom was passed down through a local rite in which the villagers(洞民) of Chuam Village ritual enshrine ichthyosaurs(魚龍), the ‘golmaegieossijono’ at the altar known as ‘songhwangsan(城隍山)’.
Specially, it is focused on Donghaesa(東海祠), which was in Chuam during the Joseon Dynasty. The state could only give an East Sea location the name ‘Donghaesa’ for its shrine. The place name of Biryesan(非禮山) is also thought to have been created by defining the shamanic ritual of the ancient Chuam area as ‘be impolite(非禮)’ an obscene shrine(淫祀). It is believed that the union of Biryesan and the altar to the local deity led to the name ‘songhwangsan’ being given to the Chuam altar. Furthermore, calling Chuam a ‘mountain’ makes sense in light of a variety of situations and traditions.
