Due to the perspective of "Ziyi" described in The Bamboo Slips of the Warring States Collected by the Shanghai Museum (2) was compared with other versions (Guodinben and the Legend of Liji); therefore the sequence of related Letters was explained. However, the researcher focused on the additional remarks as well as textual annotation and interpretation and certain results were achieved from the analysis of scholars' narrations. The aim of this research is to supplement and propose personal viewpoints in text interpretation and reading for "Ziyi" with regard to Letter 13's "伓=(不悖bi bei)" character, Letter 16's "□(詭gui)" character and Letter 17's "蔽(畢bi)" character.
