Weichang Manchu and Mongol Autonomous County

Weichang Manchu and Mongol Autonomous County is a Manchu and Mongol autonomous county located in far northeastern Hebei province, China. It lies under the administration of Chengde City, and is the northernmost county of the province, bordering Inner Mongolia to the north. In terms of area, it is the largest county of Hebei, occupying an area of 9058 km2, though, as it is located in mountainous terrain, it is rather sparsely populated,, housing 520,000 people.

The area has been historically home to Manchu soldiers, and the local dialect of Mandarin is similar to that of Beijing, though there is some Northeastern influence.

History
The area of the county was originally grazing grounds for Mongol tribes. In the early Qing Dynasty, the Auqan, Kharchin and Onnigud Mongols gave these lands as a gift to the Kangxi Emperor, who then created the Mulan Hunting Grounds in Weichang. Thereafter, it became hunting ground for the Qing royal family, Eight Banners aristocrats and Mongols.
