This paper discusses the reversion of the Kaiyuan Yuguan Statute made by Dr. Lei Wen, who is one of the research team members worked on the Tiansheng Statutes reversion program. On one hand, this paper argues that the copy-clerks of Tiansheng Statues in the Ming Dynasty made some mistakes, and brought Lei's some misunderstanding to the Kaiyuan Yuguan Statute. On the other hand, the author adopts the view that the 23th article of Song Statues in Tiansheng Yuguan Statutes is a derivative article from the Kaiyuan Yuguan Statute, and it should be kept as one article of Tang statues.
