The author went to the University of Hong Kong Library twice to transcribe and study A Record of Findings Pertaining to Juyan Bamboo Slip Files in the collection. This article will now publish the contents of "Collections of the Sino-Swedish Expedition to be taken to Sweden for study", "Interpretation Manuscript Note" (shi wen qian) and other parts, introduce the historical value of this batch of original archives, and correct the omissions of previous studies. This article also compiles all the unearthed materials about the Kara Khoto site in the text of Preliminary Draft of Juyan Bamboo Slips (Han jian shi wen chu gao). Sort out and analyze, and then study the numbering of Juyan Bamboo Slips, including many "non-Han relics", "non-Han bamboo slips" and other items left over from the Song and Yuan dynasties. In addition, using the name, shape, and package number of the artifacts unearthed in Kara Khoto as supporting evidence, it can be used to supplement the information on the excavation site in the appendix of the newly published Juyan Bamboo Slips.
