Guohua Abacus Museum

Guohua Abacus Museum It's a fascinating place. The owner used to work in an abacus factory and began collecting old and unusual versions of this ancient calculator. The museum has an abacus used by China's great statesman, Zhou En Lai, a very old porcelain one dug up while excavating foundations for a new sky-scraper in Shanghai, and others ranging from the very small to the biggest functioning abacus in the world.
