Discourse anaphora is to observe the discourse characteristics of anaphora from the perspective of discourse. Character anaphora is the central element of generating and understanding narrative text, and its understanding directly affects the reader's (listener) understanding of the text. This paper uses natural narratives published in recent newspapers and media as the corpus to explore the three forms of noun anaphora, pronoun anaphora and zero anaphora commonly used in character anaphora, analyze their differences in use and explore the selection mechanism of anaphora forms.
