A woman presents a Bagua (the Eight Diagrams) abacus of the Ming Dynasty (1368-1644) in Huizhou County, east China's Anhui Province July 17, 2006. This abacus can be used for both calculation and entertainment. A special calculating tool in ancient China, the abacus has gradually faded away from people's life at a time when computers prevailed. In Huizhou, however,abacuses can still be found almost everywhere.See also instrumental abacus, windows abacus, ring abacus and decoration abacus
