Shin Chaeho
Shin Chaeho said that Gija Joseon (323 BC-194 BC) refers to the putative period of Beonjoseon, one of the Three Confederate States of Gojoseon, after Gihu (기후, 箕詡) became the king of Beonjoseon. Chinese traditional accounts indicate that Gihu's ancestor, Gija, was the same person as Jizi (both written as 箕子 in Hanzi/Hanja).
