At his prime, he and his ally Li Maozhen the military governor of Fengxiang Circuit (headquartered in modern Baoji, Shaanxi) have a stranglehold on the court of then-reigning Emperor Zhaozong, and are able to put two former chancellors that they dislike — Li Xi and Wei Zhaodu — to death over Emperor Zhaozong's objections.

However, Li Keyong the military governor of Hedong Circuit (headquartered in modern Taiyuan, Shanxi) then attack them and defeat Wang.

Wang flees and is killed in flight by his own subordinates.
