Guangxu Emperor
Prince Duan was a cousin of the Guangxu Emperor because the emperor's biological father, Prince Chun, was the seventh brother of Prince Dun, Prince Duan's biological father. Prince Duan also had an additional layer of familial ties with the Guangxu Emperor: His wife, Jingfang of the Yehenara clan, was the third daughter of Guixiang (桂祥), Empress Dowager Cixi's younger brother. Guixiang's second daughter, Jingfen, was the Empress Consort of the Guangxu Emperor.
