What are the social reasons for the prevalence of satirical poems in Kuomintang-controlled areas?

In the 1940s, satirical poems prevailed in Kuomintang-controlled areas, and many poets wrote such poems. On the eve of the total collapse of the Chiang family dynasty, all kinds of contradictions were exposed, and the ugly and ridiculous face of the ruling class could no longer be concealed. This is the social reason for the popularity of satirical poems. At that time, among the people in the Kuomintang-ruled areas, there were already many rather spicy satirical songs. For example, a folk song in Baoji sings: half-irresponsible, not telling the truth, being shameless on both sides, ignoring the Three People's Principles, holding endless meetings everywhere, not asking about the six laws, not being afraid of eight rounds of mahjong, not wanting to pursue a career in the future, having a lot of part-time jobs in the Fifth Academy, not feeling seven emotions, not obeying the three religions, constantly holding department stores and being reviled by everyone. This is the people's mockery of the corruption and darkness of the reactionary regime. A ballad satirizing Chongqing Kuomintang officials said, "Being late for work, making jokes, sorting out drawers and grinding ink, writing private letters and reading newspapers ..." It was already a bit like Ma Fantuo's ballad.
