The Inland-water transportation Yamen was divided into two systems, the dock division and the ship transportation Division. The highest-ranking official was the transport Commissioner, a rank four official. There were nearly a thousand people in and out of the water transportation Yamen.
"Water transportation is the most profitable of all the Yamen in the Imperial court. In the 20th year of yuanjing, the Imperial court once promoted the sale of officials, all of which were related to the water transportation." As Governor Zhang led the way, he said in a deep voice,
"In the 22nd year of yuanjing, the policy of selling official titles was jointly banned by the Duke of Wei and chief advisor Wang. But in just two years, the number of worms that came in to make up the numbers was outrageous. To this day, there's still a group of people who are in high positions."
