This panda is inspired by the Jiaozi from the Song Dynasty, commemorating China's earliest paper money and one of the world's first forms of currency. In the early Northern Song Dynasty, Jiaozi was invented in Sichuan to address the challenges of heavy paper currency, which was not conducive to circulation and exchange. This initiative marked the creation of the world's first paper money, Jiaozi, which became the official currency of the state, showcasing the innovative spirit of Chengdu's economic agents and their exploration of trade convenience. It is a tribute to ancient economic wisdom.
