big ships and the river.

Yes, the Chinease people did use bigger ships on the rivers. Some of the big ships were used on the big project like when they were digging the Wild Geese Cannel. This cannel would bring the troops from the Yellow River. So which would mean that they needed the big ships to get men to the cannel, also for the work they did building the dam's and cannels. so i geuss this should answer the question!
