The Memoirs of Lady Hyegyeong, or Hanjungnok, was written by Lady Hyegyeong and recounted her ill-fated life first as Crown Princess, consort of Prince Sado, then his widow when he was executed, and later the mother of King Jeongjo. This collection of memoirs also contained considerable information about the rule of King Yeongjo, father of Prince Sado, and provided the basis of the ninth episode of the 500 Years of Joseon Dynasty.
