晋献公
In the winter of 655 BC, the 22nd year of his reign, the State of Guo was conquered by Jin. The Duke of Yu was given a part of the women and treasures sacked from Guo. Li Ke was then granted permission to station the Jin army outside the Yu capital to rest. After a few days, the Duke of Yu was suddenly informed that Duke Xian of Jin was outside the city wall of the Yu capital. The Duke of Yu quickly went out to greet him and Duke Xian of Jin invited the Duke of Yu to the Ji Mountain (箕山) to hunt. In an ostentatious display, perhaps still under the influence of the beloved planted at his court by Duke Xian, the Duke of Yu brought the entire military force stationed in the capital to the hunt in the Ji Mountain.
