[2][3][4][5][6][7] The members of the Cheongju Han clan claim descent from the sage Jizi (or Kija), who was a noble from the Shang dynasty, and rode his white horse and set a nation in "The Farthest East".

They were the descendants of Urang (友諒), the son of King Jun, the last monarch of the Gija period, during the ancient Gojoseon Kingdom.

The Cheongju Han clan is well known for the many female members who produced most royal consorts including most six queens.

They had produced six queens, five princesses consort, three royal concubines, 315 scholars, 12 Sangshin, 14 Gongshin, and 1 Daejejak throughout the Joseon dynasty.

[citation needed] A member of this clan was Queen Insu, wife of Crown Prince Uigyeong, and the first female author in Korean history, who wrote Naehun, a Confucian morality guidebook for women.
