In the seventh year of Hongwu, Zhu Yuanzhang paid a private visit to Fengyang incognito. He wanted to find out the truth about the "people's deprivation of life" mentioned in the memorial, but he was stopped and collected "tolls", and encountered the county magistrate Zhao Heng who was arrogant and loved money as much as his life. From misunderstanding him as a corrupt and cruel official, to witnessing the people of Fengyang living and working in peace and contentment and the rise of new-style workshops, Zhu Yuanzhang saw the true face of this "corrupt official" clearly through repeated reversals, and also planted the seeds of reforming officialdom.
