In the hierarchical system of nobility in Yu Country, Imperial Brothers and Imperial Princes were all enfeoffed with a fiefdom as Princes;
The son of the Crown Prince was a Commandery Prince;
The son of a Prince, if the heir, was termed Heir Prince. Other sons were Commandery Dukes, while those granted special favors were enfeoffed as Commandery Princes;
Those who inherited the title of Commandery Prince or Heir Prince were enfeoffed as Dukes of the State.
Prince Changxiang, Li Chenghe, was the second son of the previous Emperor's third younger brother and originally held the title of Commandery Duke. Because he had once indirectly saved Emperor Yu, Li Shun, during his youth, he was promoted by one rank and enfeoffed as a Commandery Prince.
This Prince Changxiang, Li Chenghe, generally resided in Xingning Square and had no previous connection with Li Ang.
