Romance of the Three Kingdoms
In the Novel, Guan Suo is the third son of Guan Yu. He doesn't appear until Zhuge Liang begins his campaign against the Nanman. He explains that "After the fall of Jingzhou, I was hidden by the Bao family from where I wanted to go to the River Lands to ask the First Ruler for a revenge against my father. But I fell in illness, which was long and severe, and I only just recovered. I was then travelling towards Chengdu to meet with the Latter Ruler, when I met the army in the south expedition. I know that vengance has been taken upon the murderers of my father. And now I want to present myself to the Prime Minister."

Zhuge Liang sent word of his arrival to the court and gave Guan Suo a post as Van Leader. He made several contributions in the southern campaign, but was not referred to in the novel again after the surrender of Meng Huo.
