[A new textual criticism on block-printed edition of Zhenjiu Dacheng in the Ming dynasty]

It has always been considered that Zhenjiu Dacheng (Compendium of Acupuncture and Moxibustion) printed by ZHAO Wenbing is the earliest version. In comparative study, it is found that there are two versions in the Ming dynasty, one is the original, stored in the Library of China Academy of Sciences and another one is the revision, stored in the Library of Tianjin University of TCM, Zhejiang Provincial Library and the Library of China Academy of Chinese Medical Sciences. The last item, Chengjiang (CV 24) in the Acupoint Indication of Conception Vessel in volume 7 is included in the revised edition, but not covered in the original one, which is the difference between the two versions. Both of the versions were in the Ming dynasty, rather than the block-printed one in the Qing dynasty.
