During the Xuanhe reign of Emperor Huizong, Zhou Decong, the warehouse supervisor in charge of the water and land transfer of grain, discovered that 500,000 dendrobium grains shipped to Yanjing were stuck in his warehouse and could not get out. The northbound land route was cut off by bandits, the warehouse was full, and the grain began to rot. The military order for urging grain said "those who delay will be killed."
A small official from the eighth rank must find a way to send food to the north within forty days, facing the blockade of his superiors, the corruption of the dock, the interception of bandits, and the urging of the empire.
