Prince Rui (瑞)
Prince Rui of the First Rank, or simply Prince Rui, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Rui peerage was not awarded "iron-cap" status, this meant that each successive bearer of the title would normally start off with a title downgraded by one rank vis-à-vis that held by his predecessor. However, the title would generally not be downgraded to any lower than a feng'en fuguo gong except under special circumstances.
The first bearer of the title was Mianxin (綿忻; 1805–1828), the Jiaqing Emperor's fourth son, who was made "Prince Rui of the First Rank" in 1819. It was briefly renamed to Prince Duan of the Second Rank (Prince Duan) between 1894 and 1900 when Zaiyi inherited the title. The title was passed down over three generations and held by four persons.
