“Sagi” Joseon Dynasty before “Nihon Shoki”

We are accustomed to hearing that Korea is the backwaters of China; but that is not the case in this study. According to 21st century theories, Korean civilization predates China by 300 years in terms of written records and by more than 1,000 years in terms of artifacts. We also know the national power of Korea, founded by the Koreans, who were the first people in Eurasia to cultivate rice and five other crops and create the Red Mountain culture from the Han Dynasty War; especially the Taeko of the Right King, who led 5,000 horses and more than 10,000 soldiers to visit the Han Emperor for a meeting. It was a gift from King Liao. Despite this, the Nihon Shoki records that Empress Kagome conquered Silla and transformed Baekje and Goguryeo into a kingdom 200 years later; and Japan claims that Nihonbu existed based on this tradition. The purpose of this paper is to demonstrate the independent logic of the ancient Joseon Dynasty in refuting these Japanese claims.
