17.126

殷延政（亦審知子。延曦湎淫虐政。數貽書諫之。曦怒遣杜建崇舉兵攻政。為政敗之。乃立建州。改國號殷。改年天德。止三年）雷氏曰（延政號殷建州三年）。

Yin: Yanzheng (also a son of Shenzhi. Because Yanxi indulged in licentiousness and cruel governance, [Yanzheng] sent him letters of admonition several times. Xi was enraged and dispatched Du Jianchong to raise troops and attack Zheng, but Zheng defeated him. He then established himself in Jianzhou, changed the state title to Yin, and changed the reign title to Tiande. It lasted only three years). Master Lei says: "Yanzheng, styled Yin, held Jianzhou for three years."
