  Besides the Guodian bamboo texts, the Mawangdui silk manuscripts, the Beida Laozi and the received text of Wang Bi and Heshanggong, there is an “ancient version” (guben) edited by the early Tang scholar Fu Yi (fl. 600). Reportedly, this version was recovered from a tomb in 574 C.E., whose occupant was a consort of the Chu general Xiang Yu (d. 202 B.C.E.), the rival of Liu Bang before the latter emerged victorious and founded the Han dynasty. A later redaction of the “ancient version” was made by Fan Yingyuan in the Song dynasty. There are some differences, but these two can be regarded as having stemmed from the same textual tradition.
