In recent years

Internet communication technology has undergone a qualitative leap

and news communication is no longer used exclusively by traditional mainstream media and professional reporters

the microphone of communication is in the hands of everyone

and the diversification of communication subjects brings about the complication of communication behaviour. In the process of communication

the audience are lost in the mass of information

and fragments of true and false information are intermingled and flooded. In the media space

emotions have become more important than facts

leading to frequent lack of facts and truths in news communication activities. Emotional venting and opinion interpretation are popular

and the post-truth age follows. After entering the post-truth era

the authenticity of news faces frequent rumours

news reversal become normal

and the media's failure to trust the people. This will cause the loss of online public opinion

the decline of media morality

the loss of public groups

and the loss of government credibility. These undoubtedly challenge the meaning of journalism professionalism.The methodological basis of the dissertation is based on the study of the literature

the application of general scientific methods (method of analysis

as well as the study of news cases.
