 This practice was initiated in 1162 by Shizong to fund his wars, and stopped three years later when war was over.His successor Zhanzong used the same method to raise military funds in 1197 and one year later to raise money to fight famine in the Western Capital.The same practice was used again in 1207 (to fight the Song and more famine) as well as under the reigns of emperors Weishao (r. 1209–1213) and Xuanzong (r. 1213–1224) to fight the Mongols.
