Once upon a time, Hwanung, the god Hwanin`s son, wanted to go down to the human world. Hwanin noticed that and let Hwanung go down to the human world with three amulets. Hwanung went to the Sindansu in Mount Taebaek, with his 3,000 followers. He managed the human world`s agriculture, morals, and 363 other fields of societal work. All these things went well.
