Abstract: In the initial narrative,Shatuo’s eastward migration to Tang Dynasty was an ordinary surrender.Shatuo belongs to the described,highlighting the achievements of the Tang Dynasty’s monarchs and ministers in the Yuanhe period,and there is no figure of Zhuye Zhiyi’s(“朱邪执宜”) suitability.It can be seen from the historical activities of Zhuye Zhiyi from the Yuanhe period to the Dahe period that he gradually grew into the highest leader of Shatuo and was paid attention to by the Tang Court.With the rise of Shatuo,Zhuye Zhiyi’s historical image,from a passive participant in major historical events,has gradually evolved into a pioneer in parallel with Li Guochang and Li Keyong.After entering the Central Plains,Shatuo reiterated the history of eastward migration to the Tang Dynasty in the Tang Yizu Chronicle.Although there were many mistakes and omissions,Zhuye’s insistence on recording nothing to Shatuo’s eastward migration to the Tang Dynasty was formed.As a result,Shatuo has a set of logical self-consistent and complete narrative history,which enhances his own legitimacy.The history of Shatuo’s restatement and the process of restatement have become a part of history and have historical value.The study of Shatuo’s eastward migration to the Tang Dynasty can more clearly and truly explore the historical process of Shatuo’s shaping its own image and enhancing its own legitimacy.
