Abstract
Based on the latest coronavirus corpus of the English corpus collection list (English-corpora), this paper aims to do the data mining of the China-related reports reported by the media of the United States, Canada, Britain, and Australia in public health emergencies. It tries to analyze how the English world media construct China's national image on the basis of the theory of evidentiality. It is found that the national media in the English world media report on China's national image show a dynamic process of "concern-worry-stigmatization-dumping." The western media made the construction of China's national image by subjective reports, objective but negative media discourse, and "double standards."
