Wang Shenzhi died in 925. His biological son
Wang Yanhan took over the realm and, in 926, declared himself the King of Min, effectively declaring independence from Later Liang's successor state
Later Tang. It was said that he did not value his relationships with brothers and, shortly after taking over from Wang Shenzhi, sent a younger brother,
Wang Yanjun, out of the capital Fu Prefecture (福州, in modern
Fuzhou,
Fujian) to be the prefect of Quan Prefecture (泉州, in modern
Quanzhou,
Fujian). He subsequently issued orders to both Wang Yanjun and Wang Yanbing, ordering them to find beautiful women to serve in his palace. Both Wang Yanjun and Wang Yanbing wrote back in rebuke, thus causing tension between them and him. Around the new year 927, Wang Yanjun and Wang Yanbing decided to jointly attack him. Heading down the
Min River from Jian, Wang Yanbing reached Fu first, and defeated Wang Yanhan's general Chen Tao (). Chen committed suicide, and the city fell. Claiming that Wang Yanhan and his wife
Lady Cui had murdered Wang Shenzhi by poison, he had Wang Yanhan publicly executed. Wang Yanjun arrived the next day, and Wang Yanbing welcomed him into the city and supported him as the acting military governor of Weiwu Circuit (威武, headquartered at Fu Prefecture, i.e., the Min realm). (Thus,
de jure, Min thus stopped being independent by this point and reverted to be a vassal of Later Tang, but was still
de facto independent.) == During Wang Yanjun's rule ==
