Chinese modern geography is the production of the interactions between West and China. George B. Cressey is a non-negligible western geographer in Chinese modern geography, who established Geology and Geography Department in Shanghai College, and trained some Chinese geologists and geographers; whose abroad and in-depth fieldworks corrected many errors in Chinese geographic texts; whose Chinese geographic research and works sharpened the understanding of Chinese geography, and promulgated Chinese geographic knowledge. At the same time, Cressey's frequent and extensive intercourses with Chinese geographic scholars promoted more modernization and internationalization of Chinese geography. Moreover, Cressey's activities, to some extent, also reflected the track of Chinese modern geography.
