《新唐书·列传·卷九十七》
王智兴从此搜刮钱财，交结权贵幸臣来沽名钓誉，开支不够，开始在泗口收税来帮助军费开支。
智兴由是揫索财赂，交权幸以贾虚名，用度不足，始税泗口以佐军须。
From then on, Wang Zhixing collected money, associated with powerful and favoured courtiers to sell his name and earn a reputation and, due to insufficient funds, he began to collect taxes at Sikou to supplement the military costs.
