Prince Cheng of the Second Rank

Prince Cheng of the Second Rank, or simply Prince Cheng, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Cheng 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 Yunzhi (1677–1732), the third son of the Kangxi Emperor. In 1698, Yunzhi was granted the title "Prince Cheng of the Second Rank" by his father. The title was passed down over eight generations and held by eight persons.
