Su Wen and Ling Shu are two independent works, and the two titles (including Needle Sutra and Nine Volumes) have been used separately, which have been recorded in the official history bibliographies of past dynasties. However, it has long been called Huangdi Neijing. This is Huangfu Mi in Jin Dynasty, who only combined the nine volumes of Su Wen and Nine Volumes (hereinafter referred to as Needle Sutra and Lingshu) into one, and the number of volumes was the same as that of Huangdi Neijing (18), that is, it was considered Huangdi Neijing, which caused these two books to lose their due historical position for a long time.
Whether Su Wen and Ling Shu are authentic versions of Huangdi Neijing has been disputed in past dynasties. Especially in the 1990s, people made a lot of textual research on it, among which Professor Zhao Mingshan's textual research was the most comprehensive.
Zhao believes that "at present, we can only take the handed down Ling Shu as the object of investigation, and combine historical records and cultural relics to judge whether it is Huangdi Neijing, as well as its writing process and age." Zhao made textual research from social background, science and technology, language, historical records, works and cultural relics. Finally, it is considered that "through the above quotation and argumentation, we can see that Su Wen and Lingshu have preserved a large number of thoughts and materials of ancient medical classics in the pre-Qin period, and also collected the theories of different medical schools. The writing years of different chapters will come first and then arrive. After long-term accumulation, one or several people will finally compile and compile the nine volumes of Su Wen. "
Zhao also compared the number of medical classics with the number of classics, and thought that there were as many as 162 articles in Lingshu, which was definitely more than 18 volumes in Huangdi Neijing. It is entirely possible for the collator to compile the contents of Huangdi Neijing and even the works of Bian Que School, Bian Que Neijing and Bian Que Waijing into Su Wen and Ling Shu, but he changed the names of Bian Que and others. According to textual research, Liu Cheng believes that these two books do have the contents of Bian Que School.
Regarding whether Huangdi Neijing can exist alone, Zhao quoted Liao Yuqun's query. Liao thinks that "there are 36 books of traditional Chinese medicine in Han Dynasty, with 868 volumes, including medical classics, prescriptions, houses and immortals", except the Huangdi Neijing 18 volume called by modern people. Why is this book so well preserved? Liu Chengzhong quoted Yu Zihan and others as saying: "The medical classics of Fang Jilue were unknown to Zhang Zhongjing in the last years of the Eastern Han Dynasty and to Wang Shuhe and Huangfu Mi in the Western Jin Dynasty, which clearly shows that the medical classics of Fang Jilue died in the war in the last years of follwed or the last years of the Eastern Han Dynasty. "Based on this, the author believes that the original Huangdi Neijing can survive alone in the war.
Based on the above analysis, we can think that Su Wen and Ling Shu are two masterpieces of traditional Chinese medicine in the Warring States, Qin and Han Dynasties, and they are a comprehensive summary of medical achievements in past dynasties. Their origins include seven medical classics headed by Huangdi Neijing. In the past two thousand years, China medicine has been developing along the road of Su Wen and Ling Shu. Su Wen and Ling Shu are the earliest medical classics handed down in China, which is also the historical position of these two books. This understanding did not damage the image and reputation of Huangdi Neijing. Why should we maintain and adhere to the empty name of Huangdi Neijing (there is no real thing)? Ten Medical Classics, edited by Yan Jirun, is an independent medical classic with Su Wen and Ling Shu. The first series of TCM books edited by Professor Shi Qi, written by Chen Nong, is named after "Medical Classics" instead of "Internal Classic", which shows that there are already leaders. Therefore, the author suggests to restore Su Wen and Ling Shu's historical position as soon as possible.
