Extended information

Business was prosperous in the Song Dynasty, and the popular currencies were copper coins and silver. During the Taizong period, 800,000 coins were minted every year. By the sixth year of Shenzong Xining's reign, the number had reached more than six million. Due to the import of goods, a large amount of copper coins and silver were outflowed from the Song Dynasty, resulting in a shortage of hard currency.

During the Huizong period, Jiaozi was renamed Qianyin and the circulation area was expanded. In the Southern Song Dynasty, it was changed to the government-run "Huizi" in 1160 (the 30th year of Shaoxing, Emperor Gaozong). The main huizi include Southeast Huizi (also called Xingzai Huizi), Hubei Huizi and Lianghuai Huizi. However, in order to prevent copper coins from flowing northward, the Song Dynasty government stipulated that only iron coins could still be used at the border with Jin.
