Songs that directly reflected feudal oppression and exploitation and praised peasant uprisings in Ming Dynasty were rarely preserved. In the eyes of feudal literati, folk songs, as "unique skills" in Ming Dynasty, did not include such ballads. But today, this kind of ballad seems to be the most cherished part of Ming folk songs. They arise from fierce class struggle, reflect the main contradictions in society and express the will and feelings of the people. There is such a folk song in Li Kaixian's Laughter: Grab the mud swallow's mouth, sharpen the iron needle, scrape the face of the golden Buddha and look for it carefully, and find something in nothingness. Quail chewing stick? Do you recognize it again and again? What happened? Stop? Armament? Rate? ! Bitter satire and ruthless ridicule, insatiable nature and vicious exploitation means. The cruelty of officialdom: one case leads to ten cases, and one case flies ten miles. A little ink on the case, thousands of blood. It effectively exposed the ruling class's demand for punishment, and some ballads directly reflected that the poor in the Ming Dynasty provided whips and absorbed bone marrow. -"Xiangxiang Laoji Yuanxiang" Innocent people are persecuted, factories and health agencies are rampant everywhere, and the darkness and horror of society can be imagined. It is this class oppression and exploitation that will inevitably lead to the intensification of class contradictions and the continuous uprising and resistance of the people. When the peasant uprising rose on a large scale in the late Ming Dynasty, folk songs became the horn of fighting and inspired the struggle of the broad masses of people. For example, seeking promotion in the morning and harmony in the evening. Recently, it was difficult for the poor to find jobs, so they opened the door early to worship the king and made them all happy. -"Ming Ji Bei lue" eats his mother, loves his mother, eats endlessly, and does not eat it. -"Sui Kou Ji Lue" Jin Jiangshan, Yin Jiangshan and Jiangshan do not accept donations. -"Biography of Li Zicheng in the Ming Dynasty" They all devoted themselves to the enthusiastic support and love of the broad masses of the people for the peasant insurgents with distinct class feelings, and washed away the slander of the ruling class on the insurgents. At the same time, these songs also widely publicized the political opinions of the insurgents and played a positive role in uniting the broad masses of the people in their struggle.
