Based on the “double evidence method”, this paper first demonstrates the relationship between Guicang (歸藏) of the Wangjiatai Qin Bamboo Slips and the classic version of Guicang (歸藏). What is more, this paper classifies and supplements the missing names according to the handed down documents; it also proves that the place named ‘Tang (唐)’ in the hexagram of “Xiao Chen made a divination on escaping to Tang (小臣卜逃唐)” in Guicang of the Qin bamboo slips is related to the place named ‘Tangqiu (湯丘)’ of “Shangtang in Tangqiu (湯處於湯丘)” in Tsinghua Bamboo Manuscripts. The special relationship between ‘Zhonghui (仲虺)’ and ‘Yiyin (伊尹)’ plus his evaluation of Xiaochen’s escape is also reinterpreted.
