Du Lingyang (Chinese: 杜陵陽; 321 – 7 April 341[1]), formally Empress Chenggong (成恭皇后) was an empress of the Jin dynasty (266–420) of China.
[3] Some historians believe that her name was simply Du Ling, and that imperial archivists mistakenly attached the character "yang" to her name later.
Du Lingyang was a daughter of Du Yi (杜乂), a mid-level official and the hereditary Marquis of Dangyang, a grandson of the general Du Yu, who contributed much to Emperor Wu of Jin's conquest of Eastern Wu.
Du Lingyang was famed for her beauty and virtues, and Emperor Cheng made her his empress on 17 March 336,[4][2] when both of them were 15.
After her death, her name was tabooed (meaning that other important people or places should not share her name) to honour her, and thus the name of the county Lingyang (headquarter in modern Southern Lingyang town, Qingyang, Anhui) was changed to Guangyang.
