Yu Nu's poems are full of controversy and arouse widespread attention. One of the reasons is that his poems abound in all kinds of unpleasant morbid body images. This study attempts to make analyses and interpretations that the bodies with illnesses and disabilities in Yu Nu's poems are different from those in the classical period, when the appearances of bodies were decided by destiny. The bodies with wounds and illnesses embody the modern people's overwork. In order to retrieve the sovereignty over the bodies, people have to transform their bodies into useless ones, the deformed ones that do not conform to the social expectation. However, the deformed bodies become the spectacles attracting viewers in the modern society. Last, a large number of pregnant women and stillbirths in Yu Nu's poems represent the body foreignization of modern people as well as the urban feelings of isolation, loneliness, and coldness. Through these analyses, we can see the poetic characteristics of Yu Nu, the Chinese avant-garde poet.
