Shangyi is a county in the northwest of Hebei province, China. It is administered by Zhangjiakou City and lies on the province's northern border, adjoining Inner Mongolia to both the north and the west.
Its position on the boundary between Hebei and Inner Mongolia places it in the transitional zone between the North China Plain and the grasslands and uplands to the north. The county seat is the town of Shangyi, from which the county takes its name.
Note that the source material describes Shangyi County in Hebei rather than a city in Shaanxi; no verified details about a Shaanxi locality of this name are available here, so only the Hebei county's established basics are given.
