Canal construction began in separate regional sections long before later dynasties connected and reorganized the network. Read the canal as infrastructure that supported grain transport, administration and urban growth, not as one project completed in a single reign. Channels were rerouted, repaired or abandoned as rivers and political priorities changed. Pair a canal museum with a surviving urban waterway to connect chronology with physical evidence. Avoid undated length claims because sources may describe different periods and components. Continue planning with the Hangzhou destination guide.
