Prince Zhuang

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.

The first bearer of the title was Šose (1629–1655), the fifth son of Hong Taiji, the second ruler of the Qing dynasty.

The peerage was renamed to "Prince Zhuang of the First Rank" when it was passed down to Šose's eldest son, Boguoduo (博果鐸; 1650–1723).

During the reign of the Qianlong Emperor, the peerage was granted "iron-cap" status, which meant that the subsequent bearers of the title would start as a qinwang (first-rank prince) by default.

The title "Prince Zhuang of the First Rank" was also awarded in 1653 by the Shunzhi Emperor as a posthumous title to Šurhaci (1564–1611), a younger brother of Nurhaci, the founder of the Qing dynasty.
