韓遂
In 211, Han Sui and Ma Chao drew up armies against Cao Cao in response to a suspected invasion of their lands. Cities throughout Hongnong and Fengyi commanderies rose in support, while Hedong Commandery remained firmly loyal, despite adjacency to the rebels. When Cao Cao marched west to confront them, his army was fed entirely by grain from Hedong, and after defeating Han Sui and Ma Chao there were still in excess of 4,000 hectolitres of grain left over. Cao Cao increased Du Ji's salary after this.
