余華《兄弟》自問世以來譭譽各半，卻仍然在國際間有著舉足輕重的地位。此次小說背景以兄弟倆人的成長歷程作為主軸，融合文革與改革開放兩個時代，訴說人性和亂世的動盪不安。本文以身體為切入，迎合余華中世紀背景的借鏡，利用身體現象學深入在學界一直以來所談及《兄弟》的身體書寫，將身體的天性和慾望補足倫理顛覆的低下書寫，讓身體不僅看作器官的呈現與暗示。更從身體感延續天性的轉變，並結合身體與社會世界的作用，提出精神的壓抑與解放，以社會─身體─世界的三種形式，呼應《兄弟》的身體敘述與社會時代的關係。

Since the publication of Yu Hua's "Brothers", the reputation has been divided, but it still has a pivotal position in the world. The background of this novel is based on the growth history of the two brothers as the main axis, integrating the two eras of the Cultural Revolution and reform and opening up, telling the turbulence of human nature and troubled times. This article takes the body as the cut-in and caters to Yu Hua’s medieval background. It uses body phenomenology to go deep into the body writing of "Brothers" that has been talked about in the academic world. The presentation and suggestion of organs. It also continues the transformation of nature from the physical sense, and combines the role of the body and the social world to propose the repression and liberation of the spirit. The three forms of society-body-world echo the relationship between the body narrative of "Brothers" and the social age.
