The Book of Changes, Ten Volumes

國朝程良玉撰。良玉字元如，歙縣人。是書所論，皆以錢代蓍之法。自序稱五歲喪明，究心卜筮，初作筮類五十篇，康熙己卯適楚，遇枯匏老人得其秘旨，因增定為九十章。然皆術家常論，無他妙旨，至家宅章以六爻兼斷六親榮枯得喪，如兄弟旺則劫財，父母旺則克子，官爻旺則災病，其說謬固難通，所論鬼神諸星兩章，穿鑿支離，尤無理解，婚姻章內不根五行生剋，不究用神衰旺，惟據卦名之美惡而論，則更乖謬矣。

This book was written by Cheng Liangyu of the present dynasty. His name is Yuanru, from Xixian county. The discussions in this book are all about the method of using coins instead of yarrow stalks for divination. In his preface, he said that he became blind at the age of five and devoted himself to the study of divination. Initially, he composed fifty chapters of "Shi Le" (Divination Categories). In the Ji Mao year of the Kangxi era, he went to the area of Chu and met an old man named Ku Pao, from whom he received the secret teachings, and thus expanded his work into ninety chapters. However, the content he discussed were common remarks among diviners, with no profound insights. As for the chapter on "Family House," it uses all six lines of the hexagram along with the six relations to determine the prosperity or decline of each element, for example, if siblings are strong, they will steal wealth; if parents are strong, they will harm children; if officials are strong, there will be illness or misfortune. Such statements are absurd and hard to understand. The two chapters discussing ghosts and spirits and various stars and malevolent influences are full of forced interpretations and are especially unreasonable. The chapter on "Marriage" does not rely on the generation and overcoming relationships of the five phases, nor does it examine the decline or strength of the useful god, but instead judges based solely on the quality of the hexagram name, which is even more absurd. (Note: This passage is a summary written by the editors of the Siku Quanshu, appended at the end of the book, not the original text by Cheng Liangyu.)
