怡亲王
When the Kangxi Emperor died in 1722, Yinzhen succeeded to the throne as the Yongzheng Emperor. In the same year, Yinxiang was granted the title "Prince Yi of the First Rank" (怡親王); this Prince Yi peerage was one of the Qing dynasty's 12 "iron-cap" princely peerages. His personal name was also changed to "Yunxiang" (允祥) to avoid naming taboo because the Chinese character for "Yin" (胤) in "Yinxiang" is the same as the one in the Yongzheng Emperor's personal name "Yinzhen" (胤禛).
