Prince Rui (created 1819)

Prince Rui of the First Rank (Manchu: ᡥᠣᡧᠣᡳᠰᠠᠪᡳᠩᡤᠠᠴᡳᠨ ᠸᠠᠩ; hošoi sabingga cin wang), 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.

The title was passed down over three generations and held by four persons.

Zaiyi (1856–1922), the third in the Prince Rui line
Zaixun (1885–1949), the fourth in the Prince Rui line
