![In his New Reading of History (1908), Shin Chaeho (1880–1936) denied Gija's civilizing role in Korea, because Gija's Chinese origin went against Shin's reinterpretation of Korean history as the history of the racially defined Korean minjok (nation).[17]](/Images/godic/202501/22/단재신채호2352.jpg")
Jizi or Qizi (Chinese:箕子; Wade–Giles:Chi-tzu, Gija or Kija in Korean) was a semi-legendary Chinese sage who is said to have ruled Gojoseon in the 11th century BCE. Early Chinese documents like the Book of Documents and the Bamboo Annals described him as a virtuous relative of the last king of the Shang dynasty who was punished for remonstrating with the king. After Shang was overthrown by Zhou in the 1040s BCE, he allegedly gave political advice to King Wu, the first Zhou king. Chinese texts from the Han dynasty (206 BCE – 220 CE) onwards claimed that King Wu enfeoffed Jizi as ruler of Chaoxian (朝鮮, pronounced "Joseon" in Korean). According to the Book of Han (1st century CE), Jizi brought agriculture, sericulture, and many other facets of Chinese civilization to Joseon. Gija was Chinese.
