水運 refers to the transportation of goods and people via water routes, such as rivers, lakes, and oceans. This method of transport has been used for centuries and is often more efficient for moving large quantities of cargo over long distances compared to land transport. In many regions, 水運 plays a crucial role in trade and commerce. Major cities often develop around ports, where ships can load and unload goods. This system supports economic growth and connects different cultures, making it an essential aspect of global trade networks.
