The best version of "Zhouyi", as far as I know, there are four Song Dynasty editions;
(1) "Zhouyi Notes" by Wei Wangbi and Jinhan Kangbo, in the library of the Minister of Fuzhou in the Song Dynasty Engraved edition.
(2) "Book of Changes" by Wang Bi of Wei and Han Kang of Jin, printed by Jianyang of Song Dynasty. According to the appraisal of Mr. Zhao Wanli, the style of Jianyang's book is beautiful, the characters are almost thin gold, and the writing has more advantages than other books. Except for the Fuzhou version of the Song version of "The Book of Changes" handed down from generation to generation, this should be regarded as the best version.
(3) "Zhengyi Zhengyi" by Kong Yingda of Tang Dynasty, a supervisory edition of the Southern Song Dynasty, which is called the Shanshu edition of "Zhouyi" by edition scholars. Because it is a single version of the classics, annotations, and commentaries before they were combined, it is the most precious. It was originally collected by the Xu family in Linqing, Shandong Province. value.
(4) Commentary on the Book of Changes by Wang Bi of Wei, Kang Bo of Jin and Han Dynasty, and Shu by Kong Yingda of Tang Dynasty. The revised version was engraved by the Tea and Salt Department of Liangche East Road in Song Dynasty and sent to Song and Yuan Dynasties. This is the first edition of the Zhouyi that contains the classics, annotations, and chapters. It is known as the Yuezhou edition, and is also known as the eight-line annotation edition. It has been included in the third volume of Guyi Series.
