Yoto

Yoto was a Qing dynasty imperial prince and Nurhaci's grandson. Yoto became the first bearer of the Prince Keqin peerage as Prince Cheng of the First Rank. He was demoted two ranks for committing a grave offence and posthumously granted a title of Prince Keqin of the Second Rank. After his death, the peerage was twice renamed until 1778, when the peerage was granted iron-cap status, which meant that each successive bearer of the title would hold undiminished title vis-a-vis his predecessor.
