王处直
However, most of Wang Chuzhi's staff members were apprehensive about inducing a Khitan incursion. Further, Wang Du, who was then Wang Chuzhi's deputy military governor and who was considered his heir, was fearful of being displaced by Wang Yu. Wang Du and the secretary He Zhaoxun () therefore plotted to arrest Wang Chuzhi. They acted after a feast that Wang Chuzhi held for Zhang's emissary to Yiwu, seizing Wang Chuzhi and put him and his wife and concubines under house arrest. Wang Du thereafter slaughtered all of Wang Chuzhi's male biological descendants at Ding Prefecture, as well as Wang Chuzhi's close associates. He claimed the title of acting military governor and reported what occurred to Li Cunxu. Li Cunxu thereafter approved of his takeover from Wang Chuzhi. (Wang Chuzhi's younger son Wang Wei () did escape and flee to Khitan territory, and Wang Wei would subsequently serve under Khitan's Emperor Taizu and his son Emperor Taizong.)
