Guo Jia
Guo Jia fell ill after departing from Liucheng (柳城; in present-day Chaoyang County, Liaoning) following Cao Cao's victory at the Battle of White Wolf Mountain in 207. He was 38 years old (by East Asian age reckoning) at that time and he died not long later. Cao Cao was very grieved by Guo Jia's death. He told Xun You, "All of you are around the same age as me; only Fengxiao was the youngest. I planned to entrust him with responsibilities before my death, but it's destined that he would die at such a young age."
