Abstract

The received version of the Zhouyi (also called Yi, the Book of Changes) is inconsistent with the version revised by Wang Bi, who adopted Fei Zhi's ancient-character (also called Zhuan shu) version of the Eastern Han Dynasty.  Drawing reference from the bamboo slips manuscript Zhouyi , we can see that the content of the received version is generally similar to the bamboo slips one, doubtlessly demonstraing that the recieved version belongs to the Zhouyi , in ancient characters and the Mawangdui silk manuscript should belong to then the new-character (of the Han Dynasty) (also called Li shu) version transmitted by Tian He in the beginning of the Western Han (206BC-25AD).  There are two reasons for this conclusion.  One is that, the time when the silk manuscript was transcribed should be during or before the reign of Emporer Wen (r. 179-163BC) and can be basically limited to the over 20 years from the reigns of Emperor Gao (r. 206-194BC) to Queen Lu (r. 187-179BC), conforming to the historical records that the transmission of he Yi hexagrams' name are evidently affected by the interpretations of the names in the Orderly Sequences of the Hexagrams (Xu Gua), being similar to Tian He's academic style.  The text of the new-character Zhouyi transmitted by Tian He includes two aspects of "new connotations" and "ancient connotations", the former involved in "virtues" and "benevolence & righteousness", the latter in divinations.  The correlation between the arrangement of the hexagrams' order by Jing Fang and that in the silk manuscript, the large number of Confucious' remarks on Yin-yang, five elements, and divination in the Commentaries of Yi copied on silk unearthed reflect that the silk manuscript Zhouyi was probably a transcription from the text of "ancient connotations' handed down by Zhou Wangsu, one of Tian He's disciples.
