Wang Yanzheng
The first reference to Wang Yanzheng in historical sources was in 931, when another older brother, Wang Yanjun, then ruling but carrying only the title of Prince of Min as a vassal of Later Tang, had defeated and executed their adoptive brother, Wang Yanbing, who had controlled the Jian Prefecture region and had tried to seize control of the Min state from Wang Yanjun. After Wang Yanbing's death, Wang Yanjun sent Wang Yanzheng to Jian to try to comfort the people, and he later commissioned Wang Yanzheng as the prefect of Jian, a post that Wang Yanzheng then appeared to remain at for the next several years.
