A few months ago, Zheng Xiang left his residence in disguise without informing anyone, choosing to wander alone through the town's farmers market and inspect whether the policies about the minimum prices for the farmers' produce were being implemented properly or not.
As the one supervising the area under his rule and responsible for sending reports to the Main Palace, Zheng Xiang wanted to ensure that the policies were being implemented correctly and that there was no corruption ongoing among the officers in charge of monitoring the execution of state policies in the area.
During his undercover inspection, Zheng Xiang discovered a widespread market monopoly. Despite the state increasing the minimum prices for farmers' produce, most merchants continued to buy items at the same low prices as before, which were significantly lower compared to the high quality of the goods that they were purchasing from the farmers.
