王審知
When Wang Shenzhi fell ill in summer 925, he had Wang Yanhan take over the affairs of the state. When Wang Shenzhi died later in 925, Wang Yanhan took over the state, but initially did not declare any regal titles, but instead only the title of acting military governor of Weiwu. (A rumor at that time — later claimed to be true by Wang Yanhan's adoptive brother Wang Yanbing — was that Wang Shenzhi was poisoned by Wang Yanhan's wife Lady Cui, but it cannot be known whether the rumor was true.)
