When Mr. CHEN, Yin-Que studied abroad in Europe, he put all his efforts to study languages. In addition to knowingly use more than twenty different languages, he also absorbed the advanced thinking in European historiography at the end of the 19(superscript th) and beginning of the 20(superscript th) century For a further step, Mr. CHEN, Yin-Que even integrated such advanced thinking in European historiography into our traditional Chinese history and created his unique thinking and manners to interpret historiography. Besides, in terms of history of the Wei, Jim, and Six Dynasties texts and the history of the Sui and Tang Dynasties, he not only had superior knowledge in those histories but also pursued historical facts and detached truth in the basis of the entire nationality's culture He always can detect big issues from tiny points and discover things that others were not able to see. This article illustrated Chen's points of view in three areas-his academic studies, his thinking on historiography and his manners in interpreting history-to uncover the achievement that CHEN, Yin-Que, scholar of no equal of his time, had accomplished in the field of historiography.
