The Study on Zhang Xuecheng (1738-1801) was very active since the Japanese sinologist Naito Torajiro and the Chinese scholar Hu shi wrote the monograph respectively in 1920 and 1922 on the life of Zhang Xuecheng (in the form of chronological biography). Zhang Xuecheng has really made contribution and has exercised influence upon the later Chinese scholars in different academic fields, especially in the field of historiography, in the field of local gazette (fangzhi) and in the field of bibliography. However, researchers have quite different opinions as well as diverse judgments on Zhang’s contribution and influence in regard of the above mentioned fields. The article aims at: To discuss and analyze the different opinions and judgments of the different researchers; to pass a judgment myself on the contribution and influence of Zhang Xuecheng regarding the three above mentioned fields.
