Wang Su (195–256),[5] courtesy name Ziyong, was an official and Confucian scholar of the state of Cao Wei during the Three Kingdoms period of China.
When Guanqiu Jian started a rebellion in Shouchun, Wang Su advised Sima Shi to lower the rebels' morale by treating their families with respect.
[6] Wang Su's daughter, Wang Yuanji, married Sima Zhao and gave birth to Sima Yan, the first emperor of the Jin dynasty, in 236.
Wang Su inherited the title and marquisate of Marquis of Lanling (蘭陵侯) from his father.
Scholars long suspected it was a forgery by Wang Su,[5] but a book discovered in 1977 from the Shuanggudui tomb (sealed in 165 BCE), entitled Ru Jia Zhe Yan (儒家者言, Sayings of the Ru School), contains very similar content to the Kongzi Jiayu.
