将盐的收入用于漕运雇工，从长江、淮河至东渭桥，大抵一万斛盐雇工费七千缗，自淮河以北，沿路设置巡院，挑选能力强的官吏主事，不烦劳州县就能完成漕运事务。
以盐为漕佣，自江、淮至渭桥，率万斛佣七千缗，自淮以北，列置巡院，择能吏主之，不烦州县而集事。
The salt revenue was used to employ workers for water transportation. From the Yangtze River and Huaihe River to Dongwei Bridge, about 10,000 bushels of salt cost 7,000 guan. Patrol courtyards were set up along the way north of the Huaihe River, and capable officials were selected to be in charge of the affairs, so that the water transportation could be completed without bothering the prefectures and counties.
