Prince Rui (created 1636)

It was also one of the 12 "iron-cap" princely peerages in the Qing dynasty, which meant that the title could be passed down without being downgraded.

He was awarded the title in 1636 by his half-brother, Hong Taiji, who succeeded their father to the Later Jin throne and who later established the Qing dynasty.

After Dorgon's death, the Shunzhi Emperor abolished the Prince Rui peerage.

In 1778, the Qianlong Emperor not only restored the Prince Rui peerage, but also granted it "iron-cap" status.

Chunying (died 1800), a sixth-generation descendant of Dorgon's younger brother, Dodo, was selected to inherit the Prince Rui title.
