Brazil's mainstream media has a large audience and high social trust. Their frequency of reporting on relevant issues in China，the choice of topics and their language organization have largely influenced the acknowledgement of the Brazilian people about China，as well as the shaping of Brazilian society's feelings toward China and the development of the China-Brazil relations. Taking into account the characteristics of various forms of media，the difficulty of data accessibility and analyzability and the representativeness of media，this essay chooses four mainstream media in Brazil as the research object and builds a China-related coverage database based on official tweets published by the Brazilian mainstream media. With the aid of technical means such as corpus software，this paper analyzes the main features of the coverage on China by Brazilian media in 2017 parting from variants like the reporting frequency，theme distribution，popularity distribution and language organization. In order to further promote China-Brazil media exchanges and show a “more authentic and lively” China in Brazil，there also have been put forward two suggestions：continue to support the Chinese media to go out and continue to support the Brazilian media to come to China；make full use of new media and technologies to promote non-governmental exchanges between China and Brazil.
