Another exhibition in the Wenxing Building, The History of Chinese Currency, presents the evolving history of money in China, from the earliest cowries, metallic currency during the Qin and Tang dynasties, and the world's earliest paper currency used by Chinese ancient people in the Song Dynasty, to the latest digital renminbi.
