Taking the change of location of the capital of Changzhou prefecture and administrative area of the Jingnan county in Tang dynasty as examples, this study points out that researchers should make use of historical documents from multiple perspectives in locating counties in the Middle Ages. We find that the position of Jingnan county in Tang dynasty is at the Taihe dam of Zhangjia dam, in Gaosheng town of Dazu county, which was called Jingnan dam and 50 miles west of Dazu county, other than Longshui town or Sanxi town in Dazu counry. The capital of Changzhou prefecture was firstly set in Changyuan county in 758, and then to Rongchang county in 769, and eventually in Jingnan county in 892. We also find that in order to ensure the reliability of research, one must make use of local historical memory, actual geographical situation and cultural relics to correct historical documents, because historical researches are prone to four types of inaccuracies, namely the sensibility of mileage calculation, the rigidity of azimuth coordinates, the fuzziness of azimuth direction and the obvious simplification and derivation in geographical cognition of historical documents.
