The allegorical couplets in the late Qing Dynasty and the early Republic of China, based on the traditional Chinese allegorical tradition, combined with the vernacular movement, have undergone different degrees of new changes in phonology, sentence patterns, techniques and other aspects. The liberalization of tone and tone rules, the vernacular use of sentence patterns and vocabulary, and the humorous use of rhetorical techniques in the late Qing Dynasty and the early Republic of China have made the allegorical couplet conform to the concept of “the integration of language and writing” at the dual levels of “form” and “spirit”, becoming a practical style of “I write what I want to say”. The allegorical couplets of the late Qing Dynasty and the early Republic of China most directly and truly reflect the aspirations of the people, serving as a powerful “combat weapon”, in the midst of laughter and abuse, to analyze the dark and tragic reality.
