Features: This book is compiled and revised in a relatively complete and systematic form, incorporating a series of papers I published from 1958 to 1969 on the history of the Five Hu and Northern Dynasties. During the revision process, both the titles and content of the papers were adjusted compared to the original versions, with several being significantly shortened. Additionally, new chapters were added to clarify the relationships between different sections and chapters. However, these revisions were kept technically focused to avoid affecting the overall theme of the book. By examining the articles written over these ten years, one can see that the content covers various periods and stages of the five Northern Dynasties' history, with most of the focus on political history. The title might be more appropriately "The Political History of the Five Hu and Northern Dynasties." However, this title was not chosen because my own academic interests in driving this research are closely connected to the formation of the Sui and Tang empires.
