He asked a second time and on receiving a positive response he made Li Ji his main wife, replacing Qi Jiang.
[1] In 665 BCE, the twelfth year of the reign of Duke Xian, Li Ji gave birth to Prince Xiqi.
Since Li Ji wanted her son to be the crown prince, she bribed two of Duke Xian's most trusted officials, Liang Wu (梁五) and Dongguan Biwu (東關嬖五).
The officials told the duke that the northern Rong and Di tribes frequently attacked Jin such that the princes were needed to defend their territory.
Moreover, Li Ji suggested that Shensheng bring back some of the sacrificial meat and wine and offer it to his father as tribute.
Discovering the poison in the food, Duke Xian sent men to Quwo to arrest Shensheng and kill his teacher Du Yuankuan (杜原款).
Chong'er escaped to the Di tribe, where his mother came from, with some of his loyal subjects: Zhao Cui, Hu Yan (狐偃), Jia Tuo (賈佗), Xian Zhen (先軫),[3] and Jie Zhitui.
After the death of Duke Xian on the ninth month of 651 BCE, Li Ji placed the 15-year-old Crown Prince Xiqi on the throne and made Xun Xi the chancellor to help him in government affairs.
