Leaf 17, last three lines: Ku Hou Qie (The original text reads "Ruo Shi Qie", which is an error; all other editions also contain this error. It is now corrected to "Ku Hou Qie" based on the original text. According to a search in *Yu Pian*, the character "Kou" (Cǎo Kūn, a type of reed) originally has the pronunciation "Ku Hou Qie". This indicates that previous corrections were not arbitrary, so we follow the original.)

Leaf 18, line 2: Mu Shi (Male Pig), Mu Shu (Male Rat) (In the original, both instances of "Mu" were mistakenly written as "Zhuang"; this is now corrected.) Line 10: Jin [damaged] Bu Wu (According to the original, the character represented by [damaged] is worn out, with traces visible at the bottom resembling the character "Shan" (Good). Both the Xue edition and Zhang edition read "Zhi" (Of), which is suspected to be incorrect.)

Leaf 20, note for the last ten lines: Qu Zi Ran Han (The character "Han" (Sweat) should be "Zhi" (Juice).)

Leaf 23, line 1: [damaged] Shen (The original is damaged. Based on the sequence of medicinal ingredients, it should be "Xuan Shen" (Scrophulariae Radix).) Last nine lines: [damaged] [damaged] [damaged] [damaged] (The original is damaged and cannot be verified; neither the Xue edition nor the Gu edition contains this. The Zhang edition reads "Yan Xi Yong" (Grind into fine powder for use).) Last ten lines: [damaged] [damaged] ([damaged] [damaged] [damaged] [damaged] [damaged] [damaged] The original is damaged. In the Xue and Zhang editions, "[damaged] [damaged]" is read as "Tang Mo" (Decoction residue), "[damaged] [damaged] [damaged]" as "Tong Shang Er" (Same as above, two parts), and "[damaged] [damaged] [damaged]" as "Zhong Li Lian". Note that the characters "Li Lian" are erroneous.)

Leaf 24, line 5: Hei Gao Wen (The character "Gao" (Ointment) should be "Gu" (Bone).)

Regarding the section on "Methods of Processing Medicines" from Leaf 20 to Leaf 23, these four leaves in the Song edition have one blank space above the list of medicinal ingredients in the upper row. The current engraving erroneously aligns them to the left margin and combines them with the diagnostic text.

Engraved in the Guiwei year of Daoguang by the Shi Li Ju of the Huang family in Wumen, calligraphy by Shi Nanjin of the same county.

Among the collectors in the prefecture, Zhu Huanwen You was someone I still had the opportunity to meet; his household possessed many books. Due to old age, most were dispersed. Among the final lot sold was Pang Anchang's *Shanghan Zongbing Lun* (General Treatise on Cold Damage Diseases), offered alongside other works. The owner did not recognize it as a Song edition, nor did the book dealers who purchased it know it was a Song edition. I placed it in a bookstore, where a knowledgeable person recognized it and exchanged it for five taels of silver (Qingfu). Since then, those of us who enjoy collecting have competed to purchase copies. This book first came to the home of Gu Baochong at Xiaodushudui. Later, Yuan Shou of Wuyanlou learned of it, and I also became aware of it. Because Yuan Shou negotiated the exchange first, it came into his possession. Baochong saw the book first and thus copied a duplicate. I have not seen Baochong's copy, but I have seen a handwritten copy by his friend, Mr. Shi Shaogu. Shaogu was teaching children calligraphy at Baochong's house at the time, so he borrowed and copied it. After copying, the original returned to Yuan Shou, and I commissioned craftsmen to make a facsimile copy from him. In total, there is one Song edition, and regarding the Song-facsimile copies, there are three: those by Baochong, Shaogu, and myself. Later, I exchanged my facsimile copy for the Song edition with Yuan Shou, and the book became part of the collection in Baishong Yichan (Hundred Song Editions Studio). In recent years, due to financial constraints, I donated it to Yi Yun Shushe. Unexpectedly, Yuan Shou's facsimile copy also eventually found its way to Yi Yun after his death. Thus, both the engraved and manuscript copies are now owned by others, while I possess nothing. During the winter when I was engraving Hong's *Jiyan Fang* (Collected Verified Prescriptions), I suddenly had a dream. Someone said to me, "Why not reprint Pang's *Shanghan*?" Waking up, I found this strange, so I discussed it with Yi Yun, hoping to borrow the manuscript copy for printing. However, Yi Yun refused to lend the facsimile copy for publication but agreed to lend the Song edition for collation. Fortunately, Daoxiang, the son of Shaogu, willingly donated his ancestor's handwritten work to the printers. Consequently, I compared the Song edition with the facsimile copy and realized the significant value of Shaogu's copy. The book consists of three volumes and thirty-three leaves. Only Shaogu's facsimile copy contains this specific portion; my version lacks it entirely. It is likely that after Shaogu copied it, Baochong began his copy but accidentally omitted it during transcription. From then on, the Song edition lacked this leaf, and subsequent facsimile copies also lost it. If I had not reprinted it, one would not know that the Song edition lacked this leaf; if Shaogu had not made his facsimile copy, one would not know that the Song edition originally contained it. The弊 (drawbacks) of books being disassembled and transmitted through copying are such, and this must serve as a warning. Regarding Volume 5, Leaf 15, the Song edition is missing this leaf. Only the manuscript copy from the Xue Xingtian family possesses it, but the handwriting and layout differ significantly from the original, and the source is unknown. Later, I saw that Baochong's copy also included this leaf, which he stated was supplemented from Wang Yutai's movable type edition. For my current reprint, I supplement it based on the Xue edition and collate it with the Gu edition, preserving differences. The Song edition also contains errors. I further borrowed manuscript copies from the collections of Zhang Shitang, Xue Xingtian, and Gu Rongan. Although it is unknown if they share a common source, any differences in characters are marked. Where appropriate, the main text is modified to conform; where uncertain, collation notes are retained for reference. My friend, Mr. Zhang An, who is well-versed in medical principles, assisted in collating and determining dozens of corrections. The responsibility for proofreading and initial drafting fell to my eldest grandson, Mei Li. Since Wang Yutai's movable type edition was printed, no new editions have appeared. Even the Wang edition, passed down through generations, consisted of only two hundred copies, making it extremely rare in circulation. My nephew once owned a copy, which was lent to a friend and subsequently burned, leaving me regretful that I could not collate it. Friends all longed to see this book and were eager to view it, so I ordered craftsmen to print it. As for the profundity of this book, former friends of Anchang, Lords Su (Dongpo) and Huang (Tingjian), had already explained it in detail. There is no need to solicit additional remarks from contemporary renowned scholars who are also proficient in medicine.
