The hypothesis put forward by Wei Zhengtong and Xu Fuguan, that Xunzi had never read the Mencius, is questionable. This paper seeks to prove that there are matching passages shared between the Xunzi and the Mencius. By the same token, this paper further examines the relationship between the “Xing e” chapter found in the Xunzi and the “Xing shan” chapter which was lost from the extant version of the Mencius. The author also tries to prove that the “Xing e” chapter was written by Xunzi’s followers or disciples instead of Xunzi himself.
