Di Xin obliged King Wen of Zhou to stay in You (that is, today’s Henan) for almost seven years, during which King Wen of Zhou’s eldest son, Bo Yi Kao, came to the capital of Shang, Zhaoge (today’s Hebi, Henan) and ask for Di Xin’s mercy. The fox spirit fell in love with the handsome young man, and requested Di Xin to permit Bo to teach her play the guqin.

Taking advantage of the guqin lessons, Daji ensnared Bo with her splendour. Bo, however, refused Daji for any liaisons, and called her a shameless woman. The irate Daji made a complaint to her husband that Bo had bullied her. Gnashing his teeth, Di Xin killed Bo and minced him into paste, cooked it into congee and served to King Wen of Zhou.

King Wen of Zhou knew divination, and, by means of the Eight Diagrams, he realised the congee was made from his beloved son. Suppressing the great pain and sadness in his heart, King Wen of Zhou ate up the congee and determined to avenge his dead son.
