Zhao Yi had an insight into the trend of Chinese history when he was doing research on Chinese historiography,and explicated his thought of "Tang-Song Historiography Transition ",that is,from the Tang Dynasty to the Song Dynasty,the types of historical records changed from rhythmical prose characterized by parallelism and ornateness to ancient prose,and the method of historical compilation changed from copying raw materials to innovational compilation,and the authors of historical books changed from single author to official historians who compiled historical records separately.Influenced by Zhao Yi ’s thought,Naito Konan advanced his own theory of "Tang-Song Historiography Transition ".Through a study of his views,evidences,logic,train of thought and its formulation,we can learn that he carried on and developed Zhao Yi’s thoughts and took the point further.Its reason is that Naito Konan’s idea,style of research and his academic view and nature agreed with those of Zhao Yi’s.
