《旧唐书·本纪·卷二十》
三月初一，朱全忠带着军队回到汴州，上奏朝廷说： 河中节度使每年上交税盐三千车，现在由我代管盐池二处，请允许我加二千车，每年上交五千车税盐。
三月癸未朔，全忠引军归汴，奏： 河中节度使岁贡课盐三千车，臣今代领池场，请加二千车，岁贡五千车。
On the first of March, Zhu Quanzhong led his army back to Bianzhou and reported to the imperial court that the Jiedushi of Hezhong sent 3,000 carts of taxable salt annually. Now that I am in charge of the two salt lakes, I ask to add 2,000 carts and send 5,000 carts of taxable salt annually.
