Wang Du
Also in 928, Wang Du, who had been concerned about an imperial government takeover of his circuit, partly because An had begun to reimpose imperial laws on Yiwu whereas Yiwu had acted independently previously, tried to assassinate the imperial general Wang Yanqiu, whose army was then stationed near Yiwu's capital Ding Prefecture () in anticipation of a potential Khitan attack. Emperor Mingzong declared a general campaign against Wang Du, with Wang Yanqiu in command. In 929, Wang Yanqiu was able to capture Ding Prefecture, despite Wang Du's being aided by the Khitan general Tunei (); Wang Du committed suicide, allowing the imperial government to take over Yiwu.
