Zhang Binglin
On par with Mencius, Zisi is attacked by Xunzi in his famous "Against Twelve Masters" chapter. The target of Xunzi's attack is the Wuxing teaching. According to Zhang Binglin (1868-1936), Zisi attempted combining Confucian teaching with the principles of numerology. Li Xueqin suggests that it was done under influence of the text presently constituting the "Great Plan" (Hongfan) chapter of the "Shangshu".
