The fox spirit who seduced the last king of the Shang dynasty is Daji. In later Chinese legends, she is portrayed as a malevolent fox spirit who takes the form of the king’s consort.
Historically framed tradition identifies Daji as the favorite consort of Di Xin, also called King Zhou of Shang. Early records describe her as a human woman and blame her influence for the king’s extravagance, harsh rule, and neglect of state affairs. The Shang dynasty fell to King Wu of Zhou around the eleventh century BCE.
The fox-spirit element developed later, appearing by at least the Han period and becoming especially prominent in medieval and Ming storytelling. In Fengshen Yanyi, a thousand-year-old nine-tailed fox kills the real Daji and possesses her body before entering Di Xin’s court.
That distinction is often flattened in quiz questions: Daji can mean the historical-style consort, the legendary possessed woman, or the fox spirit herself. In the standard mythological version, however, Daji is the canonical answer. Nie Xiaoqian belongs to a different supernatural tale, while Bai Suzhen is the White Snake.
