The origin of Korean petroglyphs was investigated mainly in Inner Mongolia and Liaoning provinces, China, but there was no research in the Heilongjiang Province area, so we looked at the “海林市 群力” Petroglyphs in the Heilongjiang Province. These petroglyphs feature drawings of deer and ships. There are various views in Chinese academia about the time of the production of the petroglyph, from the perspective of prehistoric times to Eupru(挹婁) or Okjeo(沃沮), Malgal(靺鞨) and Balhae(渤海). In addition to revealing the origin of rock art on the Korean Peninsula made during the Neolithic and Bronze Age, Okjeo(沃沮), Eupru(挹婁) and Balhae(渤海) in the historical era are also closely related to the Korean people, so more attention should be paid to the research on the origin of Korean history.
