Jinwushu Grain Station, also known as Suihua Sifangtai, is an important marginal part of Acheng Jin Dynasty ruins community. Its geographical location is in Sifangtai Town, Suihua, Heilongjiang Province, and it is the site of the military grain storage base of A Jin Dynasty. Sifangtai Town is located in the hinterland of the Longjiang River in the northland, beside the Nuo Min River. It is the largest market town under the jurisdiction of Beilin District of Suihua City and an important commodity distribution center in the north of Suihua City. Named after a square earth mountain in China, it is said that it is the point of Jin Wushu (the statement that Jin Wushu points to the platform has been denied by experts). Ruins of the site can be seen faintly in Daikin history. According to Suihua County Records, brick arches and clay pots were found in the southwest of Tutai in the 1970s. In addition, when working in the field, the rusty arrow clusters were picked up in the field.
