Along with the Zeng state and a band of Quanrong nomads he attacked the Western Zhou capital at Haojing.
You was killed in the assault whereupon the Marquesses of Shen and Zeng, together with Duke Wen of Xu (許文公), enthroned Ji Yijiu as king of Zhou and relocated the capital to Luoyi.
According to the Zuo Zhuan: The Xinian Annals (繫年) of the recently unearthed Tsinghua Bamboo Slips gives his posthumous name as King Hui of Xie (攜惠王) and records him as a younger brother of King You of Zhou.
[4] Tang dynasty (618–907 CE) scholar Kong Yingda noted that the Bamboo Annals contained the words "Han, Duke of Guo, enthroned Yuchen at Xie" inferring that Xie was a place name.
The New Book of Tang links Xie with Feng (豐), Qi (岐) and Li (驪) as parts of the ancient province known as Yong Province (雍州), thus adding weight to the theory that Xie was a location.
