《三国志·吴书·贺全吕周钟离传》
其时丹杨、吴、会稽的山民再次作乱为寇，攻陷三郡所辖县城，孙权分析三郡的险要地域另置东安郡，让全琮兼任郡太守。
是时丹杨、吴、会山民复为寇贼，攻没属县，权分三郡险地为东安郡，琮领太守。
At that time, the mountain people of Danyang, Wu, and Kuaiji rebelled again and became bandits, capturing the county towns under the jurisdiction of the three counties. Sun Quan analyzed the dangerous areas of the three counties and placed Dong'an County, and let Quan Cong concurrently serve as the prefect of the county.
