The China Water Transport Museum fits Huai'an particularly well, because the city sits in the long history of the Grand Canal and inland shipping. Exhibits cover boats, canal administration, trade routes, and the way water transport shaped towns across eastern China.
It is most interesting when read as local context rather than a generic transport museum. Huai'an's historic role is easy to miss on a quick visit; this museum helps connect the city to the larger canal system that moved grain, officials, soldiers, and goods for centuries.
