Abstract: We think the character “YI” is a mistake of the character “隋” in Hengfang Stele of Han Dynasty,“褘隋” has the same pronunciation as “委蛇”,which is in MaoshiGaoyang.According to Yuan Xingzong,Lishi holds that the character “褘隋” comes from Han Shi Neizhuan;Han Shi did not disappear in the reign of emperor Xiaozong of Song Dynasty.Those,who think that Han Shi disappeared after the Five Dynasties or between the Zhenghe and Jianyan or had disappeared for a long time in the Song Dynasty,are all wrong.

Key words: YI, Hengfang Stele
