Susan Sontag argues that illness is the internal spiritual status that becomes a language spoken through the body, and is therefore a form of self-expression. There have been plenty of studies of Eileen Chang's (1920-1995) novels, and the discussion of narratives on illnesses in her works is not new. Cao Qiqiao, the Madwoman in the Attic depicted as a patient of tuberculosis with symptoms of hysteria, anorexia and uterine diseases, has long been a focus of recent scholarship. These are certainly common illnesses found in modern Chinese literature. The present essay, however, is an attempt to discuss Chang's writing on illnesses that have not yet been studied. Hence, the present research focuses on illnesses such as tuberculosis in The Withering Flower, cholera and constipation in The Red Rose and the White Rose, and anorexia and dyspareunia in Little Union. It explores three types of morbid bodies in Chang's novels: exhausted and ugly bodies; confined and self-imprisoned bodies; and internally injured and self-abandoned bodies; and discusses their significance as well as their aesthetic functions. The description of the body is essential in the discussion of narratives of illnesses because by means of its formidable power illness functions in implying or indirectly depicting the protagonist's changes in physical and psychological condition as well as her life dilemmas. Furthermore, the research explores the connection between certain encounters and certain diseases. Making use of historical sources, the analysis of texts may become more in-depth; we see that the morbid bodies in Chang's novels by no means exist in isolation but are imbedded in a contextual picture of history, society, and gender
