China Nantong Abacus Museum
The city of Nantong, situated at the north bank of the Yangtze river’s estuary, not only houses China’s oldest museum (the Nantong Museum, founded by Zhang Qian in 1905) but also some of its weirdest. China Nantong Abacus Museum, located by the Haohe River, offers a permanent exhibition covering 6000 square meters, making it the world’s largest museum dedicated to the history of the abacus.
