There are two extant versions of Fu ke cai zhen (Collected Essentials of Women Disease) nowadays, namely, Yang Jichun's hand-copied version, and block-printed version of Direntang Sanctum. The former one was formally sorted out by Prof. Wang Yaoting of the Changchun College of TCM and published in 1988 in the Jilin Journal of TCM in serial form. Though Yang's version was completed later than the block-printed one, however, it can be found by careful comparison that it was not copied after the block-printed edition, but probably written from the draft of the author himself.
