Zhou Shan is an invented character of Romance of the Three Kingdoms, and Chinese Wikipedia states plainly that no such person existed in history. Wikidata and Chinese Wikipedia both name him Zhou Shan, so the title is unchanged.[1][2]
In the novel
According to the Chinese Wikipedia article, he followed Sun Ce from childhood and, after Sun Ce's death, followed Sun Quan as one of his household generals. When Liu Bei entered western Shu, Zhou Shan was ordered to Jingzhou to bring Lady Sun, Sun Shangxiang, back to Wu. On the way he was intercepted by Zhang Fei and Zhao Yun and killed by Zhang Fei. The article cites chapter 61 of the novel, in which Zhao Yun cuts off the river crossing to recover Adou and Sun Quan sends a letter to turn back Cao Cao.[2]
What Wikidata records
Wikidata lists his occupation as military officer, his allegiance as the Sun Quan of the novel, his manner of death as homicide, his killer as the Zhang Fei of the novel, his place of death as the novel's Jingzhou, and the setting as the novel's country of Han.[1]
