曹宫 / Cao Gong (Western Han)

Overview

曹宫 / Cao Gong enters the wiki through Hanji 571 as the palace woman whose newborn son by 汉成帝 becomes the core case behind the later Chengdi heir-killing accusation. The source presents her through 谢光’s investigative report rather than through an independent biography.

Current Profile

Cao Gong is described as Cao Xiao’s daughter, formerly attached to the central palace, and as a woman who had taught the Shijing to 赵飞燕. In the reported case, she becomes pregnant after contact with Han Chengdi in 12 BCE and gives birth to a boy that October.

Her significance lies in how quickly childbirth becomes secrecy and coercion. Chengdi’s note orders Cao Gong, the infant, and six attendants confined while forbidding inquiry into the child’s sex or father. A later order delivers pills to Cao Gong; before taking them, she says the Zhao sisters want to monopolize power and stresses that the child is male and resembles 汉元帝. She then dies, while the infant is removed later and disappears from the record.

Key Characteristics

• Western Han palace woman whose reported son becomes central to the Chengdi heir-killing accusation.
• Connected to Zhao Feiyan through palace literary instruction before the later accusation field.
• Source-scoped mother of a boy said to be Chengdi’s son.
• Victim of confinement and forced death in the reported edict chain.
• Speaker whose dying statement frames the case as Zhao-sister power suppression.
• Evidence node rather than proven full biography; her story is mediated by Xie Guang’s later report.

Evidence

• Palace identity: Hanji 571 says Cao Gong was Cao Xiao’s daughter, belonged to the central palace, and taught the Shijing to Zhao Feiyan.
• Pregnancy and birth: Hanji 571 says she became pregnant after Chengdi had relations with her and gave birth to a boy in October 12 BCE.
• Secret confinement: Hanji 571 says Chengdi’s handwritten note had Cao Gong, the infant, and six attendants jailed while suppressing questions about the infant.
• Forced poisoning: Hanji 571 says Cao Gong took pills delivered with an imperial note and died.
• Dying accusation: Hanji 571 says she accused the Zhao sisters of wanting to dominate the realm and emphasized the child’s male sex and resemblance to Emperor Yuan.

Qualifications

The source does not reconstruct Cao Gong’s whole life, her own political network, the full text of the documents, or the infant’s final fate. Because the episode itself stops before the final answer, Cao Gong’s case should be used as evidence for the reported suppression chain, not as independent proof of every later interpretation.
