Duke Xian of Jin
In 665 BC, the twelfth year of the reign of Duke Xian of Jin, Li Ji gave birth to 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 two officials persuaded Duke Xian of Jin to let princes Shensheng, Chong'er and Yiwu leave the capital, Jiang (絳). The officials told the duke that the northern Rong tribes (戎族) and Di tribes (狄族) frequently attacked Jin such that the princes were needed to defend their territory. Duke Xian then sent Shensheng to defend Quwo (曲沃), modern Quwo County in Shanxi. Duke Xian also sent Chong'er to defend the city of Pu (蒲), northwest of modern Xi County in Shanxi, and Yiwu to Erqu (二屈), modern Ji County in Shanxi.
