Zheng Chouyu's "Mistake" can be considered a poem about boudoir resentment. Boudoir resentment is a theme often expressed in ancient Chinese poetry, and there are many famous chapters. For example, Liu Yuxi's "New makeup should face the Zhulou, and the spring scenery is locked in the courtyard."; Wen Tingyun's "Thousands of sails in the past are nothing, the slanting light is long, the water is long, and the heart is broken by Bai Pingzhou"; Ouyang Xiu's "How deep is the courtyard? Willow There is a pile of smoke, and the curtains are countless.” We can find the shadow of this poem in the artistic conceptions created by previous generations. Zheng Chouyu's "Error" is only about 90 characters long, but it has become "the swan song of modern lyric poetry". In addition to beautiful words and deep connotations, it also continues the tradition of boudoir poetry in the past, implicitly and lingeringly describing the lingering entanglement of a woman waiting in her boudoir. The image of a delicate and helpless woman is deeply rooted in the hearts of the people, and has won the favor and sympathy of readers.
