The author of "Zhan Guo Ce" has not yet been verified: it is generally deemed, after Zhang Xincheng, that the book was not written by a single author at one time. It is thought to have been composed by Su Qin and his peers before being obtained by Liu Xiang. Unlike most of the pre-Qin classics, the authenticity of "Zhan Guo Ce", along with the "Shijing", "Mozi", "Yulingzi" and "Gongsun Longzi" had never been questioned since the Western Han period. The earliest to assert the texts were apocryphal scriptures was perhaps the compiler of the Annotated Catalogue of the "Siku Quanshu", but he provided no warrant for it. In 1931, Luo Genze put forward an argument that the book was composed by Kuai Tong () in his two papers based on six conclusions which he drew, a contemporary of Han Xin. Although this argument had been seconded by Jin Dejian (1932) and Zu Zhugeng (1937), but by 1939 it was refuted by Zhang Xincheng.
