This is a Chinese name; the family name is Guan.
Guan Jing (died 199), Shiqi (士起), was a military general serving under the warlord Gongsun Zan during the late Han Dynasty period of Chinese history. In 199, Gongsun Zan, being hopelessly besieged in the Battle of Yijing by Yuan Shao's army, committed suicide by self-immolation. Knowing this, Guan Jing nobly rushed into the army of Yuan Shao and died, following his lord's fate.
