王延鈞
Wang was said to be distant from his brothers, and shortly after he took over control of the state, sent his younger brother Wang Yanjun out of the capital Fu Prefecture to be the prefect of Quan Prefecture (泉州, in modern Quanzhou, Fujian). Further, he was gathering many women among his people to fill his palace. Both Wang Yanjun and an adoptive brother, Wang Yanbing, who was then the prefect of Jian Prefecture (建州, in modern Nanping, Fujian), both advised him against it, but he refused to listen, causing friction between him and both of those brothers. Around the new year 927, Wang Yanbing and Wang Yanjun jointly attacked Fu Prefecture. Wang Yanbing arrived first and defeated Wang Yanhan's general Chen Tao (), causing Chen to commit suicide. That night, Wang Yanbing took his soldiers, scaled the walls of the city, and entered, capturing Wang Yanhan. Wang Yanbing publicly accused Wang Yanhan of crimes, including murdering their father Wang Shenzhi along with Lady Cui, and executed him. When Wang Yanjun arrived shortly later, Wang Yanbing supported him to be the new acting military governor of Weiwu.
