Abstract: The Manzhou Shilu ( Chronological Records of Manchu) is an official book that records the origin of the Manchu ancestors and Nurhaci's deeds.This article discusses the origin of the precursor of the Manzhou Shilu———the Taizu Shilu Zhantu and its relationship with the Taizu Shilu.It clarifies that the Taizu Shilu Zhantu is not Manzhou Shilu and demonstrates that the first six of the eighty-three pictures were drawn during the Qianlong reign. Furthermore, the eight volumes of the Shilu mentioned in a poem composed by Emperor Qianlong actually referred to the Taizu Shilu Zhantu, not to Manzhou Shilu as the previous scholars argued．Given the above evidence，this article argues that the Manzhou Shilu is a forged book and that Emperor Qianlong himself took a role in the forgery process. This article also discusses the motivation of the forgery and the historical value of the Manchou Shilu．
