Abstract: Freedom of speech and right of reputation are the basic rights for citizens, because of the mutual relationship of rights and different value-orientation between the two, conflicts often occur in practice. We should further perfect constitutional prescription, define the scope of freedom of speech, regulate freedom of speech in criminal and civil law, strengthen operability, differentiate the right of reputation between public figures and ordinary people, and strengthen the inspection of legality of commercial speech to better the current conflict solving mechanism between freedom of speech and right of reputation.
