Zhu Yuanzhang hated corrupt officials the most, but Song Tingyu, the magistrate of Peixian County, was a "giant corrupt". He sells official positions and earns tens of thousands of taels per year; he buys shares in private workshops and shares dividends; he even dares to sell the "Royal System" sign. However, under his rule, Peixian County did not pick up items on the road, did not close its doors at night, and the people were prosperous. It was called a paradise. When Zhu Yuanzhang couldn't bear it anymore and was about to skin him and make him into grass, the people in the county jointly signed a letter: "Master Song is greedy, but he is a good official! If you want to kill him, you must get through us first!" Zhu Yuanzhang looked at the people kneeling on the ground and fell into deep thought.
