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 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. Cao Cao was made governor of Dunqiu County, following his assignment as Captain of the Northern District of Luoyang.
