A New Comment on Yi Yin,the Wise Prime Minister of Early Shang Dynasty

About Yi-Yin's study is stilled in wrong areas,because of many reasons.Firstly,many instruction datum all considered that Yi-Yin was a slave of You-Shen shi who was good at cooking and used dainty as a metaphor to say politics,thus he was thought highly by Cheng Tang.Some scholars think that Yi-Yin was not a slave,but was a sorcerer or was a leader of religion,who helped Tang to build Sang.This saying is popular nowadays,however,according with Yi-Yin's political behaviors,there was not any evidences to testify Yi-Yin was a leader of religion or a sorcerer,therefore,it is not a reliable saying.Secondly,there were two sayings that were equated,these sayings were lack of choice and judgement.One saying was that Yi-Yin putted Tai-Jia at Tong Gong,three years ago,Tai-Jia came back and became a good king.Another saying was that Yi-Yin seizured the power,sever years ago,Tai-Jia came back and killed Yi-Yin.Afterward,some scholars pointed out and corrected,but the degree of demonstration was not enough,so the influence was weak.This text considered that Yi-Yin was a sage chancellor of Xia dynasty,who had political wisdom and had rich political experience.He left Xia to Shang dynasty,which was a choice between good king and sage chancellor and was the necessary opportunity of history.The text also considered that the evidence of saying about Tai-Jia killed Yi-Yin was not enough,only Yi-Yin taught Tai-Jia was right.The text overruled the saying of Yi-Yin was a religious leader.
