Shanghu is a former city of China, located in the Jiangsu region. It is recorded as a historical settlement rather than a present-day urban centre, and it is distinct from other places that share or resemble its name.
Details of its founding, administration, and eventual decline are not well documented in readily available sources. What is established is its status as a former city in Jiangsu, placing it within one of China's oldest and most densely settled regions along the lower Yangtze and the eastern seaboard.
Because surviving information is limited, Shanghu is best understood as a historical place name rather than a current destination. Travellers and researchers seeking it should consult specialised local histories and gazetteers of Jiangsu for further detail.
