The court ordered the casting of Ganfeng Quanbao money to replace Kaiyuan Bao Tong. This time, we not only made a lot of money, but also revised the monetary system and even changed the name of the currency. In order to ensure the circulation of new currency, Tang Gaozong also banned private casting, and offenders were sentenced to death. However, after the new money came out, the merchants refused to use it and could not circulate at all. The following year, I had to write to abolish this large sum of money and tell the world that Kaiyuan Bao Tong was a "law for all generations" and would not carry out monetary reform in the future. After the circulation of Ganfeng Quanbao is prohibited, it still has the function of storing value and can be exchanged.
