Prince Qin of the Second Rank (å¤é¡çÂÂ) was a Qing dynasty princely peerage. The peerage was created in 1684 for Yunduan, Nurhaci's great-grandson and son of Prince An of the Second Rank Yolo. As Prince Qin of the Second Rank peerage was not given iron-cap status, each successive bearer of the title would hold diminished ranks vis-a-vis his predecessor.
