Qingfeng County

Qingfeng County is a county located in the northeast of Henan province, bordering the provinces of Hebei to the northwest and Shandong to the east. It is under the administration of the prefecture-level city of Puyang. In the Han dynasty, Dunqiu County (simplified Chinese: 顿丘; traditional Chinese: 頓丘) was located somewhere near this area, possibly to the southwest of the modern day county. At the time, it was a part of Dong Commandery (simplified Chinese: 东郡; traditional Chinese: 東郡). Cao Cao was made governor of Dunqiu County, following his assignment as Captain of the Northern District (北都尉) of Luoyang (the capital at that time).
