Doubts concerning Confucius' authorship of the Wings were expressed by Ouyang Xiu (1007-1072) and Sima Guang (1019-1086) during the Northern Song dynasty. They were further consolidated by Yao Jiheng [zh] (1647-1715) and Kang Youwei (1858-1927) of the Qing dynasty. The 20th-century sinologists provide argumentation for rejection of the traditional creed.^[1]
