First of all, Guangzhou has a larger water area and a longer coastline than Shanghai, which is more suitable for water traffic activities. Secondly, Guangzhou has more ports and ships than Shanghai, which can meet more water transport needs. Finally, Guangzhou has more advanced water transport facilities, which can meet the water transport demand more effectively.
In short, from the current point of view, Guangzhou's water transport capacity is much better than that of Shanghai, which can better meet the water transport demand. However, with the development of the times, Shanghai is also actively improving its water transport capacity, striving to improve port facilities, improve port management, and speed up the loading and unloading of ships to better meet the water transport demand. I hope that Shanghai's water transport capacity can also reach the level of Guangzhou in the future.
