The Ming Dynasty directly reflected feudal oppression and exploitation, and few ballads praising peasant uprisings have been preserved. In the minds of feudal literati, folk songs, which were regarded as "one of the best" in the Ming Dynasty, did not include such ballads. But today, it seems that this kind of ballads are the most cherished part of the folk songs of the Ming Dynasty. They were produced in the fierce class struggle, reflected the main contradictions of society, and expressed the will and feelings of the people. There is such a folk song in Li Kaixian's "Yixiao San": Seizing the mud swallow's mouth, whittling the iron needle, scraping the golden Buddha's face to search carefully, and finding something in nothing. Quail Kun chewing americium bareng stem? Rengan admits repeatedly? 猓? Rice carbuncle drum relegation posthumous title? Halt? Bone board Ren? Rate?! Pungent satire and ruthless ridicule, insatiable nature and vicious means of exploitation. The brutal and brutal modern bureaucracy: one case leads to ten cases, and one case spreads ten miles away. A little ink on the case, a thousand drops of blood among the people. It effectively exposes the demands of the ruling class and some ballads directly reflect that the poor are willing to be whipped and the rich are sucking the marrow. ——"Old Collection of Yuan Xiangqi" The innocent people are being persecuted, factory security agents are rampant everywhere, and the darkness and terror of society can be imagined from this. It is this kind of class oppression and exploitation that will inevitably lead to the intensification of class contradictions and the continuous uprisings and resistance of the people. When peasant uprisings broke out on a large scale in the late Ming Dynasty, folk songs became a clarion call for battle, inspiring the people to fight. For example: Seeking promotion in the morning and harmony in the evening. It is difficult for poor people to make a living these days. Open the door early to pay homage to King Chuang. Everyone, big or small, will be happy. ——"The Northern Strategy of the Ming Dynasty" Eat his mother, live with his mother, and there will be king Chuang if you don't eat enough, you won't be on duty, and you won't pay for food. ——"Sui Kou Chronicles" Jin Jiangshan, Yin Jiangshan, the king of the country will not accept donations. ——"History of Ming Dynasty: Biography of Li Zicheng" They all expressed the people's enthusiastic support and love for the peasant uprising army with clear class sentiments, and washed away the slander of the ruling class against the uprising army. At the same time, these ballads also widely publicized the political ideas of the insurrectionary army and played a positive role in uniting the broad masses of people to fight against each other.
