 (1644–1911). The primary purpose of the cáoyùn was tax collection, since grain was a major payment method accepted by the imperial administration. The system also played a secondary role as a distribution network for army provisions whilst management of shipbuilding and tariffs also fell within its ambit.

Every year, regulations fixed the total amount of tax payable by the entire country in grain via the Cáoyùn system at 29.5 million bushels.

 whilst 8.2 million bushels were used to supply Beijing.

From 1415 onwards, imperial regulations stated that the Cáoyùn system should use only the country’s canal network thereafter all seaborne transportation stopped.
This situation remained virtually unchanged until the beginning of the 19th century and as a result, during both the Ming and Qing Dynasties, the volume of Cáoyùn grain transported via the Grand Canal far exceeded that of the preceding Yuan Dynasty.

During the Ming Dynasty the usage pattern of the Cáoyùn system went through three successive phases. At first the "zhiyun" (支运) variant evolved as grain tax transportation switched from the sea to the country’s canal and river network. At Huai’an, Xuzhou

 and other locations, warehouses were established to store taxes paid in grain and delivered by the local population. This was then shipped north to provision the army once every quarter. Storage became unnecessary with the advent of the "duiyun" (兑运) form where taxes paid by the common people were partly used to directly pay the transportation fees for army supplies on the journey north. During the third stage known as "changyun" (长运) or "Gaidui" (改兌), the army took responsibility for the movement of grain from south of the Yangtze River.

According to Ming Dynasty scholar Qiu Jun (邱濬): “Use of the river and canal network saved 30–40% of costs compared to road transportation whereas the savings achieved using sea-borne transport were 70%–80%.”
