Abstract
The academic community generally believes that Zhang Yichao(张议潮)regained Suzhou(肃州)and Ganzhou(甘州)in the third year of Dazhong Reign while this paper argues that this view could not be established.The time for Zhang Yichao to recover Suzhou and Ganzhou should be between July of the tenth to twelfth year of Dazhong Reign.Some scholars believe that Shangbibi(尚婢婢)formed an alliance with Zhang Yichao or even attached to Yichao.However,through the route selection of the Guiyi Army's(归义军)entry in the fifth year of Dazhong Reign and some Dunhuang documents,it is reflected in the Guiyi Army's hostile to the Shang Bibi and other prefectures.We believe that the relationship between Shang and Guiyi Army is not harmonious.
