Showcased during an abacus-themed exhibition held in the Chinese city of Taiyuan, Shanxi Province, this large pavilion model is made from 668 different-size abacuses. Used as a calculating tool centuries before the adoption of the written numeral system, the abacus is a big part of Asian culture, and is still widely use by merchants and clerks around Asia and Africa. Apart from the impressive abacus pavilion, visitors at the exhibition could admire over 100 abacuses, from the simplest to more complex versions.
