Jiamusi was first named Giyamusiduring the Kangxi period by the Nanai people. The word Giyamusi originally means Inn in Manchu Language. Because of the harsh climate and short growing season, the region of today's Jiamusi City was largely uncultivated . Since the Qing government opened Manchuria for farming in order to oppose the conquest of Russia, Jiamusi developed as a small trading post under the name Dongxingzhen.
