Abstract: One's body is the gathering place of ideographic symbols and the body communicates with the self and the outside world through various symbols. In this sense, the body symbol plays an important role——carrying and conveying the subjective and objective meaning of human beings.Kafka's writing world consists of a variety of body signs, such as voice, posture, expression in one's eyes, facial expression and action. These body signs reflect their profound significance in a unique way. In the interweaving of continuous changing body symbols and their context, the author and the reader are trying to deduce the possible meaning conveyed by the semiotic text. This paper is an exploration of the multiple meanings of body signs written by Kafka, hoping to further think and extend the Kafka's world of signs.
