Jiaqing Emperor's sons

Qing-dynasty Chinese emperor (1782–1850)

Miankai (綿愷; 6 August 1795 – 18 January 1838), was a prince of the Qing Dynasty. He was the third son of the Jiaqing Emperor and was made the first holder of Prince Dun of the First Rank peerage. He was the elder brother of Mianxin born by the same consort, Empress Xiaoherui.

Mianxin (綿忻; 9 March 1805 – 27 September 1828) was Qing dynasty imperial prince as the fourth son of the Jiaqing Emperor. Mianxin was made the first holder of the Prince Rui of the First Rank title in 1819. In contrary to existing iron-cap Prince Rui of the First Rank peerage, the first character in the title was translated into Manchu as "sabingga". The peerage was not extinct as Mianxin had a legitimate male heir and the peerage was not granted perpetual inheritability, which meant that his successors would hold diminished ranks.

Mianyu (綿愉; 8 March 1814 – 9 January 1866) was Qing dynasty imperial prince as the fifth son of the Jiaqing Emperor and the first holder of the Prince Hui of the first rank title. As Prince Hui of the First Rank peerage was not granted iron-cap status, each successive bearer of the title would hold diminished rank vis-a-vis his predecessor.
