The provincial system originated from the platform of Wei and Jin Dynasties, when it was a temporary institution for the central government to handle military affairs. The rulers once set up a station in Shangshu province on the border. After the Mongols entered the Central Plains, they imitated the Jin Dynasty system and set up Shangshu Province, which governed a large area of counties in Lufu, and evolved into the highest local political authority. In the middle of Yuan Shizu, Shangshu Province was merged into Zhongshu Province, and the local organization was renamed Zhongshu Province.
