[Study on the author and its edition circulation of Ao shi shang han jin jing lu (Ao's Records of Golden Mirror on Cold Pathogenic Diseases)]

Based on Ao's original work, Du Qingbi compiled Ao shi shang han jin jing lu (Ao's Records of Golden Mirror on Cold Pathogenic Diseases) . Though someone claimed that Ao shi shang han jin jing lu was an expert of Confucian classics, Ao Jiweng in the Yuan dynasty, unfortunately, no records reveal that he had been related to medicine, and it needs further investigation. It was seldom known since the completion of Ao shi shang han jin jing lu. Thanks to Xue Ji' of the Ming Dynasty who blockprinted this work twice and then it began to circulate. In addition to its circulation as a monograph, it was attached to other medical works as appendix as another significant form for circulation, mostly attached to Gu jin yi tong da quan (A Complete Medical Book, Ancient and Modern) and Zheng zhi zhun sheng (Standards for Syndromes and Treatment) . It was transmitted to Japanand Vietnam and was especially famous in Japan. Currently, scores of versions of Ao shi shang han jin jing lu exists in Japan. On the basis of Ao shi shang han jin jing lu, new works on tongue diagnostics did appear, such as Shang han guan she xin fa (Mastering Tongue Diagnostics in Cold Pathogenic Disease) and Shang han she jian (Lingual Mirror for Cold Pathogenic Disease) , thus further pushing the transmission of tongue diagnostics.
