Jizi
Jizi, Qizi, or Kizi (Chinese: 箕子; Wade–Giles: Chi-tzu), called in Korean Kija (Korean: 기자; RR: Gija), was a semi-legendary Chinese sage who is said to have ruled Kija Chosŏn 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.
